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. 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.
CemMate 100 Grinding type cement grinding aid Description CemMate 100 is a kind of grinding type cement grinding aid. By the use of CemMate 100, without the new investment and change of existing cement grinding process equipment, it can be realized that: - Mill output is increased; - Energy cost is reduced. Scope of the application Suitable for grinding of any kinds of cement, slag powder, steel slag powder and limestone powder. Property Appearance Brown liquid Specific gravity 1.16±0.05 PH value 9±1 Insoluble matter â?¤ 0.01% CemMate 100 is non-toxic, non corrosive, non flammable, non explosive. Technical characteristic - Increasing mill output. This product can effectively remove the electrostatic agglomeration due to grinding, reduce the agglomeration between cement particles, and the agglomeration between particles and pound mills. The mill output can be increased by 10ï½?20%. For the grinding of slag powder or steel slag powder, the mill output can be increased by ï½?10%. - Reducing energy consumption. The electricity used in the production of per ton of cement can be saved by 6ï½?10 kw/h. - Others. There is no corrosive effect on grinding equipment and concrete reinforcement. Basically, it does not affect cement setting time and water consumption of standard consistency. Cement strength can be increased slightly. It has no adverse effect on the work performance, mechanical properties, deformation performance and durability of concrete. Dosage The dosage of CemMate 100 is related to the physical properties of materials to be grinded. The recommended dosage is 300 grams / tons of materials to be grinded (0.03% of cement weight). Usage method In order to achieve the most stable using effect, CemMate 100 shall be accurately added by an adjustable liquid metering pump that matches the type and output of the mill. The liquid metering pump must be calibrated before use. CemMate 100 can be added to the belt conveyor or the front of the mill. Technical service Professional engineers can combine the details of the cement plant to make experiment and recommend the mill parameters to the cement plant. CemMate 100 is one kind of cement grinding aid. According to the condition and demand of cement plant, professional engineers can design the most suitable cement grinding aid for many kinds of cement from cement plants to adjust cement performance, such as: setting time, water requirement of normal consistency, fluidity, adaptability of cement concrete, etc. Package 200 L/drum, intermediate bulk container. Storage CemMate 100 should be stored indoors or in the shade. Avoid freezing. If it is frozen, melt it slowly before use. After long term placement, it should be stirred or shaken before use. The validity period is one year. We provide free sample for mini mill test and technical support throughout the whole application process. We look forward to the cooperation with the agent worldwide.
