Sodium metasilicate pentahydrate enhances the suspension of removed soils such as grease and dirt deposits and prevents reaccumulation. For this reason, it's commonly used in manufacturing high-efficiency in soaps, detergents, and metal cleaners. It is extensively used in the manufacturing of Detergents, Silica Gel, Card-board, Paper, Textiles, Paints, Adhesives, Pottery, Sanitary-ware, Refractories, Foundry and Wood Processing Industries because of it's very good binding, adhesive, bleaching and sizing properties respectively.

Glycolic acid is a colorless, odorless liquid and the smallest I±-hydroxy acid (AHA). It is used to manufacture adhesives, dye, print, medicines, and crease-proof textiles. Glycolic Acid is also used in leather dyeing, as a tanning agent, in detergents, welding agent, adhesives, plastics, oil well acidification, electroplating, copper pickling, printed wire board flux, soldering products, etching lithographic plates, iron chelating, chemical milling, metal cleaning and demulsifier. Glycolic acid is often included into emulsion polymers, solvents and additives for ink and paint in order to improve flow properties and impart gloss. It is used in surface treatment products that increase the coefficient of friction on tile flooring. It is the active ingredient in household cleaning products like Pine-Sol. Glycolic acid is an outstanding choice for a broad range of cleaning applications due to its dual functional groups, hydroxyl (OH) and carboxyl (COOH). The dual functionality enables exceptional cleaning performance for mineral and hard water scales.

pu wheels for skate board 80*44 PU Wheels custom logo pu pulley for skateboard Product: PU wheels/pulley for skate board, 80*44mm, 78A, black, Customized Why there are thousands of types of wheels? The wheels have specific features of hardness, size, shape...and color, printing... When choosing materials, it should be considered to be suitable for different ground roads, such as floor roads, cement roads, asphalt roads and so on. No matter what road you slide on, the wheel must be flexible, wear-resistant, and moderate in hardness. It must also ensure that the wheel has enough friction coefficient on the road surface. The first is hardness, and the skateboard wheel is usually a polished polyurethane. The proportion of polyurethane in the wheel is different, and the hardness of the wheel is also different. A wheel with a hardness of 85A(A refers to hardness) is relatively soft and suitable for rough pavement taxiing. The sound is minimal when taxiing. It is a good choice for friends who like to go shopping. However, the 85A wheel is relatively non-wearable because it is soft, and it is easy to break the interval layer when doing things such as side skid brakes. In general, today's skaters use 97A-103A wheels. This kind of hardness wheel is suitable for smooth marble and relatively flat roads, as well as U pools, platforms and other props. Wheels such as 85A at smooth leveling are also soundless. But in rough places and on the U pool, there will be a huge rumble(this sound often makes the racer boil). The transparent or translucent wheel does not use 103A. It is too hard and will burst. It is best to use only props made of all WOOD materials. Followed by the diameter, the 38-40 mm wheel is now used by very few people. This wheel starts and accelerates quickly, but the stamina is small, and it is only suitable for very flat roads. It is characterized by a fairly flexible movement. Friends who like small movements can try. And the rebound, the rebound of the wheel is very important. Although there are no parameters to refer to. However, the stronger the rebound, the stronger the ability to overcome obstacles. If you don't know how well your wheels bounce back, you can do a little experiment. Remove the bearings in the wheel, you throw the wheel hard on the ground, rebound the high wheel, the wheel will bounce to the ceiling, the bottom rebound wheel, will only jump on the ground two times. On the smooth ground, perhaps, the two wheels can run as fast, but in the slightest rough road, the advantage of high-rebounding wheels can be immediately demonstrated. Our main products are long board wheels, skateboard wheels, shock absorbers and skateboard accessories and some other products. And we also have a plastic injection plant to produce some skate board accessories, such as the core of pulley. For more information, please click here.
pu wheels for skate board 83*44 customized pu pulley for skate board Product: PU wheels/pulley for skate board, 83*44mm, 78A, yellow, Customized Why there are thousands of types of wheels? The wheels have specific features of hardness, size, shape...and color, printing... Skateboards wheel, 4 units for one set, are made of polyurethane. Wheels have different diameters, shapes and hardness. Small wheels start fast, but lack of stamina, suitable for skills; large wheels can easily glide on less flat ground. Skateboards are also very particular. In addition to bearing accuracy (such as ABEC1, ABEC3, ABEC5, ABEC7, etc.) has an impact on speed, it depends on the performance of the wheel. Good abrasion resistance, good bounce, When choosing materials, it should be considered to be suitable for different ground roads, such as floor roads, cement roads, asphalt roads and so on. No matter what road you slide on, the wheel must be flexible, wear-resistant, and moderate in hardness. It must also ensure that the wheel has enough friction coefficient on the road surface. Followed by the diameter, the 38-40 mm wheel is now used by very few people. This wheel starts and accelerates quickly, but the stamina is small, and it is only suitable for very flat roads. It is characterized by a fairly flexible movement. Friends who like small movements can try. The 45mm -50mm wheel is the most suitable wheel for the road type. 52-60mm wheels are more suitable for use on props. Because the action on the props requires strong power, the flat action hopes that the lighter the board is, and the weight on the props can sometimes bring more inertia and impact, making you taller and farther. In the wild, you can use more than 60mm of cross-country wheels. Professional mountain skateboards use large rubber wheels. And the rebound, the rebound of the wheel is very important. Although there are no parameters to refer to. However, the stronger the rebound, the stronger the ability to overcome obstacles. If you don't know how well your wheels bounce back, you can do a little experiment. Remove the bearings in the wheel, you throw the wheel hard on the ground, rebound the high wheel, the wheel will bounce to the ceiling, the bottom rebound wheel, will only jump on the ground two times.
