It provides a tough and attractive finish for tennis courts, basketball courts, etc. It is suitable for internal and external sports floors. It is an easy to apply water-based coating with excellent water resistance.
Surface preparation
New concrete should be left for at least 21 days to cure before coating.
The moisture content of the concrete surface should be checked and ensured to be below 6% when measured with a reliable moisture meter, such as the Sovereign Moisture Meter.
The surface to be coated must be clean and free from all loose extraneous materials such as loose paint, dust, etc.
If fungus or algae is present, first treat with Berger Fungicidal Wash and leave for 24 hours.
Then, thoroughly rinse and wash or scrape away all the fungus.
If grease is present, clean using a mild detergent or solvent and rinse thoroughly to ensure complete removal of the grease, detergent and solvent.
Apply a suitable sealer coat such as Berger Plastaseal or Berger Water-Based Sealer prior to application of this product.
For overcoating over old coatings, high pressure water cleaning should be performed to remove all loose or flaking coatings and ensure the remaining coatings are tightly adherent.
Flexographic, Gravure and Sheet Fed Offset Printing
Flexography (Flexo) printing uses a raised-image printing plate. Photopolymer, or rubber, plates are used to transfer the print image. Conventional liquid or sheet photopolymer plates are used for line art. Laser-imaged, direct-to-plates (DTP) are used for all four-color process, all duotone, and most halftone images. As the plate cylinder rotates, it comes in contact with an anilox, or ink roller, which inks the raised portion of the printing plate. The plate then transfers the ink to the web, or paper. The anilox roll is laser-engraved with thousands of recessed cells that fill up with ink. The doctor blade controls the ink transfer to the plate. The doctor blade wipes off all ink except what is in the cells of the anilox roll. Compared to offset printing, this method offers significantly more ink transfer. (Refer to diagram below)Get more news about Flexographic Flat Printer,you can vist our website!
There is "gain," or growth, of Flexo images. For example, if the image area is a process/halftone with a 2% dot in the art/plate (typically the minimum for Flexo), it will print between 9-12% dot on coated papers and 12-15% dot on uncoated papers. This gain occurs for several reasons: As mentioned, the amount of ink transferred increases the image dot size. The contact pressure to transfer from anilox to plate to paper also increases the image dot size.
The substrates needed to ensure efficient machineability of roll paper into bags are not as smooth as those in offset printing. A rougher sheet can increase the size of the image dot because it requires more plate pressure to print. In addition, more ink is absorbed in a rougher paper. There also is more inherent machine movement in Flexo than in offset printing, so registration is not as tight and larger traps between colors are required.
Flexo can maintain resolution levels of 65-110 line on uncoated papers (such as Kraft and white) and 110-133 line on coated papers (claycoat).Gravure prints from a "cut-in," or recessed, surface. An engraved metal printing cylinder is used to transfer the printed image to the paper. As the gravure image cylinder rotates in the ink pan, the engraved cells of the image are filled with ink. The doctor blade controls and meters the ink by wiping the excess from cylinder surface, leaving ink only within engraved cells. The gravure cylinder then comes in contact with the paper substrate, transferring the printed image with the help of the rubber impression cylinder, which pulls the ink from the engraved cells. (Refer to the diagram below.)
There is "gain," or growth, in gravure printing. For example, if the image area is a process/halftone with a 3% dot in the art/cylinder (typically the minimum for gravure), it will print between 5-7% dot. Gravure is excellent for printing strong metallic inks.
Gravure prints on rolls of the same claycoat paper as Flexo and therefore has many of the same characteristics. However, gravure offers tighter registration that requires minimal traps and can maintain resolution levels of 150-175 line.
Shipping times and costs from United States of America to France
France is a European country with a bit of everything. Hear the name and people don’t know what to think of first. There’s the wine and cheese, the cosmopolitan cities, the countryside villages, the snowy mountains, the Mediterranean beaches, the list goes on and on. It’s not surprising that France is one of the most popular tourist destinations in the world. Of course, the icing on the French cake is Paris, Europe’s most fashionable city and home to some of the most iconic buildings in the world. If you’re thinking of moving to France, you’re bound to find somewhere that suits you.Get more news about France Shipping,you can vist our website!
When moving internationally, there are two main shipping options available: sea and air. Sending your belongings by plane is faster but comparatively expensive, while using a container ship is slower and cheaper. At MoveHub, we recommend that you choose ocean shipping as it’s much better value for money and you can fit more in a shipping container. It just requires a bit of advanced planning. You also need to choose between a Full Container Load (FCL) and a Less than Full Container Load (LCL), which is based on how much stuff you’re bringing. Most of our suppliers will provide you with a full door-to-door shipping service, but it’s best to check with them before you agree on any terms.
France is well served by big, experienced shipping ports all along its coastlines. The largest French port is Marseille-Fos, which sits on the Mediterranean coast and deals with most of the containers heading into southern France. At the other end of the country is Le Havre, France’s second largest port and one of the main entry points for northern-bound cargo. Other big ports include Dunkirk, Brest and Nantes. Believe it or not, there are also some pretty major inbound ports, such as the Port of Paris and the Port of Lyon. So, you can rest assured that France has more than enough ports.
If you want to get your container through French customs without any major hiccups, it’s wise to meet all their requirements. Most importantly, you need to declare all the items that you’re bringing into France by creating an inventory. Make sure you are clear and specific so that the customs officials know what is supposed to be inside each box. It’s also very important that you get your hands on a Certificate of Change of Residence from the French Consulate. This is proof that you’ve lived outside France for the past 12 months and it will help you avoid paying any duty on your goods. Don’t worry, your shipping company will help you with the French customs process. See below to see which items are prohibited at the French border.

If you've always just bought whichever extension cord happens to be sitting on the shelf at your local hardware store, you're missing out on cords that are safer, more durable, and more flexible than the ones most commonly available at brick-and-mortar retailers. After spending more than 40 hours researching over 55 different extension cords, talking with two safety experts, and testing 12 of the most promising for flexibility-some even in zero-degree temps-we recommend the U.S. Wire & Cable 50 FT. Extreme All-Weather Extension Cord. For a more stylish indoor option, we like the Cordinate Décor Extension Cord with 3 Grounded Outlets.Get more news about Extension Cord,you can vist our website!
The U.S. Wire & Cable 50 FT. Extreme All-Weather Extension Cord offers an excellent combination of functionality and usability. The thick, 12-gauge wires inside are rated to handle up to 15 amps-as much as most residential breakers will allow-making it safe to use with most tools and equipment. It's also the most flexible cord we've ever used, so it's as easy to work with in the height of summer heat as it is the depths of a near-zero-degree winter. The outlet end has a small LED that lights up when the cord is live. If you're going to own only one extension cord, the 50-foot version is versatile enough to maneuver across a two-car garage, run between two rooms indoors, or stretch deep into a yard or driveway. We've seen it priced anywhere between $50 and $75, which may induce some serious sticker shock, but it's a reasonable price for a high-quality extension cord that can survive even the harshest conditions and has a lifetime warranty.
If the U.S. Wire & Cable isn't available, we also like the Southwire 1638SW0061 Polar/Solar Supreme Extension Cord. It has all the same characteristics of our top pick but is a little stiffer, making it a bit trickier to coil up at the end of the day.
Another very similar option is the Clear Power CP10091 50 ft TPE Rubber Heavy Duty Extension Cord, which proved easy to handle. It's a little stiffer than our main pick but otherwise offers the same powering capabilities, and it has a locking switch at the plug end that prevents whatever you're plugging into it from disconnecting accidentally. It's a decent feature, but we have suspicions about the mechanism's long-term durability. Also, there are enough other ways to secure the plugged connection of an extension cord that we don't think this is necessary.
If you live in a warmer climate and don't need a cord that's flexible through the cold depths of winter, we also like the Iron Forge Tools 12/3 SJTW Heavy Duty Yellow Outdoor Extension Cord. It has the same power rating as our other picks, but the cable sheath is made of a different material (the kind most hardware store cords are made of), so it's stiffer in general and won't be as loose in colder temperatures. In our testing it sat flat on the ground, but it's harder to spool than our other picks.
If you need an indoor cord just to plug in a lamp or phone charger, the 10-foot Cordinate Décor Extension Cord with 3 Grounded Outlets is the best choice. Unlike many inexpensive cords for indoor use, the Cordinate has a third prong for grounding, which provides extra protection against electrical shorts and shocks. Plus, it has a flat plug that's less likely to be bumped out of the socket by furniture, pets, or people; half-plugged cords and damaged wiring can increase the risk of fire. Some other indoor cords share these characteristics, but what really sets the Cordinate apart is that it's available in a wide array of colors. Cords like these aren't meant to be used outdoors or with high-power tools and equipment-they're intended only for low-power use around the home or office.

If you're slowly starting to build your home theater system, the first thing you probably picked out was a pair of speakers. This is only the beginning, though. Whether your setup is for movies, music, games, or all of the above, a powered subwoofer is one of the key components of a complete audio system.Get more news about fashion subwoofer speaker,you can vist our website!
In the words of Meghan Trainor, a subwoofer is all about that bass. It's the speaker that delivers the lower frequencies - specifically 20-200 Hz - that a traditional two-channel or surround sound setup can't reproduce on its own. These low frequencies come from instruments such as the kick drum, bass guitar, and pipe organ, as well as movie sound effects like explosions.
While you may hear the bass from your bookshelf or floorstanding speakers, a subwoofer allows you to feel the sound. Listening to bass-heavy music like hip hop or EDM or watching a full-throttle action flick without a subwoofer leaves a lot to be desired. Plus, you're not experiencing the song or movie the way the artist or director intended.
You might be asking yourself: I don't listen to rap or watch action movies, so why do I need one?
Sure, a subwoofer is a bass-thumping juggernaut, but that's only scratching the surface. A great subwoofer helps take away the heavy lifting from your loudspeakers, improving your overall system.
The dynamics are more compelling, the soundstage widens, and the stereo imaging becomes more accurate. Even if you prefer spinning folk records and watching dialogue-driven indie dramas, a subwoofer helps produce a more vibrant, all-encompassing sound.Honestly, you can place your subwoofer anywhere. But since all rooms are constructed differently, the results are going to vary. If you're serious about getting optimal bass performance from your subwoofer, there may be some trial and error involved.
We get it. Not everyone has a dedicated home theater or listening room with the flexibility to place your subwoofer anywhere. Most likely, your system is located in your living room, which means décor, furniture, and other things are competing for floor space. You might have to rearrange some stuff, but it's worth it to find the "sweet spot."
Along with placement, acoustic treatment is another factor to consider if you want to get the most out of a subwoofer. You can have the best subwoofer on the planet, but when it's in an acoustically poor room, expect subpar bass performance. Acoustic panels, diffusers, and bass traps are all excellent ways to improve your room's acoustics. Plus, many modern A/V receivers come equipped with room correction technology such as Audyssey and AccuEQ. It calibrates each speaker to create a more harmonious home theater experience.Placement can also be determined by whether you've opted for a down-firing or front-firing subwoofer. While there's no discernible difference between how each option sounds, there are certain factors you need to evaluate depending on the space you're looking to fill, specifically whether you're placing the sub in a home or an apartment.
How to Select a Coin Cell Battery Holder for Maximum Shock and Vibration
Lithium coin cells like the CR2032 have found their way into a multitude of portable electronics applications, many of which will require battery replacement. To be end-user friendly, designers must ensure coin cells are mounted in battery holders that make battery replacement simple and fast. At the same time, the battery holder must have a robust design that maintains good connection to the cell even in the presence of shock and vibration. Cell holders must also offer safe retention of the cell and protect against inadvertent short circuits.Get more news about Cerall Battery Box,you can vist our website!
On the manufacturing side, the cell mounts must be designed for automated pick-and-place production with a clear separation of connections. Cell mounting designs should be available with either surface or through-hole mounting.
This article looks at the concept behind these battery holders, reviews their unique features and benefits, and reviews design considerations when selecting coin cell battery holders. It then introduces and shows how to apply the Snap Dragon series of coin cell holders from Memory Protection Devices (MPD) that use a non-conducting, snap-in cover to address designers’ concerns.
To address these design requirements, MPD introduced the Snap Dragon series, a whole new category of cell holders. These greatly increase the reliability of open-top coin cell holders through the use of a locking, snap-on cover that prevents shock, vibration, and drops from dislodging the cell or causing intermittent connections. To meet the user-friendly requirement, the cover can still be removed in a “snap”, allowing for quick and easy battery replacement.
For manufacturing, the device’s liquid crystal polymer (LCP) base is tolerant of high-temperature reflow soldering processes. The snap-in cover is not only designed for ease of use, its use of polypropylene material means it is strong and flexible enough to allow multiple battery replacements over time. Even with these features, the Snap Dragon holders keep a very low profile, typically adding only 1 millimeter (mm) to the coin cell battery above the pc board.
Taking a closer look, the Snap Dragon coin cell battery holders use a two-piece design consisting of a snap-on battery retainer and a mating base, which together hold the cell (Figure 1).
While some high-reliability cell holders can make user battery installation and replacement difficult or impossible, the Snap Dragon cell holder is designed to offer an easy and intuitive process. The Snap Dragon design is patent pending and is the newest addition to MPD’s portfolio of battery holder technologies.
Snap Dragon coin cell holders are available in two different sizes to fit BR/CR2032 and BR/CR1225 cells in either horizontal or vertical orientation. They can be supplied with either tabs for surface mount technology (SMT) soldering or pins for through-hole mounting on a printed circuit board. These cells offer up to approximately 220 milliamp-hours (mAh) of power and are quite small, making them perfect for circuits with low power requirements in handheld portable devices (Figure 2).
Do Kids Need E-Mountain Bikes?
Rarely has a piece of test gear caused so much controversy in our household. Ski boots, bikes, fly rods, camp showers—all manner of gear lands on my doorstep for review, and my husband and ten-year-old daughter greet every item with curiosity. But unboxing the Woom UP 6 ($3,749), an e-mountain bike for kids, triggered emotions ranging from anger to elation.To get more news about rad rover 5, you can visit magicyclebike.com official website.
My daughter, Simone, the bike’s intended tester, cooed over the gleaming blue finish on the UP’s aluminum frame, the 90-millimeter air fork, the Schwalbe Rocket Ron tires on 26-inch wheels, and the Fazua motor–battery unit that boosts pedal strokes with up to 250 watts of power.To get more news about waterproof bag for bike, you can visit magicyclebike.com official website.
My husband, Ben, was less enthusiastic. He hates it when speedier e-bikers buzz past us on paved bike paths and uphill stretches of singletrack around our home in Steamboat Springs, Colorado. “I don’t want her becoming one of those assholes,” he muttered.To get more news about tektro aries, you can visit magicyclebike.com official website.
Safety is another consideration. Commuter e-bikes have become increasingly popular among our local tweens and teens, who fit onto the smallest adult frames from companies such as Haibike, Pedego, and Trek. Fitted with panniers and racks, e-bikes let kids pedal themselves to lacrosse practice or violin lessons. But they’ve also elicited concern: Isn’t it dangerous to hand out motors to people with undeveloped prefrontal cortexes? Around Steamboat, it’s become common to see kids zooming their motorized cycles down the middle of the street or crowding several of their helmetless friends onto the handlebars and top tubes.Now brands are starting to manufacture kids’ e-mountain bikes. Haibike makes the child-size Sduro HardFour ($2,710), with 24-inch wheels. Commencal sells the Meta HT 24 Power ($3,000). And this month, the Austrian kids brand Woom launched its e-mountain-bike models in the U.S. The UP 5 ($3,599) has 24-inch wheels and fits seven-to-eleven-year-olds; the UP 6 ($3,749) features 26-inch wheels and fits ten-to-fourteen-year-olds.
Despite our obvious apprehension, I was intrigued by the idea of an e-mountain bike for Simone. Her dad and I have always invested in top-quality kids’ bikes in an attempt to help our daughter love mountain biking as much as we do. Wanting to increase her chance of success on the trails and minimize any undue suffering, we’ve sought out the most lightweight builds (most kids’ bikes are way too heavy for them to pedal for any real distance) and we’ve insisted on models with geometries and components optimized for children’s proportions. Why not extend that continuum of optimization to e-mountain bikes, I reasoned, given their potential to boost my child’s pedaling power?
To be sure, Simone’s first ride around the neighborhood on the Woom UP 6 made her giddy with elation. “It exhilarates so fast!” she hooted, mistaking exhilarates for accelerates. I didn’t correct her, because she was right on both counts.
The UP 6 lets riders choose from three levels of pedal assistance, adjustable by pressing buttons located on the top tube. Colored lights indicate the three modes, with blue for the least motor support (100 watts), green for medium (200 watts), and pink for the most powerful (250 watts). Even in blue mode, she reached cruising speed over flat terrain within just two or three effortless pedal cranks.UP’s factory settings turn off the motor’s pedal assist once the rider has reached 12 miles per hour (well under the 20-mile-per-hour limit for Class 1 e-bikes). That makes it easier for her to get started from a stop, or to ride uphill, but it doesn’t make her fast overall—not on pavement, at least. I can still keep up with her and even leave her behind on my cruiser bike. She’s just speedier off the line.
On dirt, though, the UP zooms her way out ahead of me. Our first off-road ride with the UP 6 was at an e-bike-friendly singletrack network in the nearby town of Oak Creek. Our uphill route included a mix of steep dirt paths and two-track lanes that showcased the bike’s advantages. Simone pedaled easily up the hills, stopping now and then to wait for me as I crawled along in my granny gear. “I feel like a show-off,” she fretted.
“Are you using the blue setting?” I asked. “No, the pink,” she admitted. “I can’t help it. It’s so fun, not feeling out of breath!” The motor support had already turned her into an addict. But at least she was a happy addict: on her regular bike, she would’ve been complaining about the effort or settling into grim resolution.Weighing 37 pounds, the UP 6 is heavier than many kids’ mountain bikes (Simone’s Trailcraft Pineridge 24 weighs 23 pounds). But as an e-bike, it’s quite light, compared with the 41-pound Commencal Meta HT 24 and the 44-pound Haibike HardFour. That’s because UP takes many of its build cues from Woom’s nonelectric frames, which feature feathery aluminum and typically rank among the lightest available options for each rider size.
Even so, Simone actually enjoyed the UP’s heft once we stopped climbing and tipped our bikes downhill onto rock-studded singletrack. There the bike felt more stable than her lightweight rig. “I don’t feel like I’m getting bucked around as much,” she reported. We’d adjusted the 90-millimeter air fork to her preferred settings for compression and rebound damping, and the suspension did an admirable job of soaking up both slow- and high-speed hits.
The Promax hydraulic disc brakes (with a 160-millimeter rotor on the front and 140-millimeter rear) let her modulate her speed on steep descents and rock rolls that required precise braking to avoid skidding out. The grips, saddle, and pedals are all sized down for smaller riders, so they felt comfortable for her. And the SRAM NX1 drivetrain and trigger shifter earned her approval for responsiveness.
