EPE pearl cotton applicator is a coating machine developed for the large-area coating of hot melt on pearl cotton (aspp, EVA ) (especially some hand-operated sheets), easy to use, and very efficient. high. EPE EPE particularly suitable for further processing industry (assembly, assembly, lamination, bonding, complex), depending on the design of the glue on the adhesive material and product demand, glue thickness can be adjusted. It is characterized by full Closed, not easy to leak glue, easy to clean the glue; roller bearing plug-in design, long life, low failure, in the state of glue melting can be repaired without stopping, does not affect production; completely solve the temperature overshoot phenomenon, not yellow plastic, with shovel High temperature resistance does not drop the coating, it does not change color and black for many years; more importantly, it is evenly coated, high in efficiency, and can reduce a lot of manual investment.
Low carbon USS flat washers, typically used with Grade 8 or hardened steel bolting, are used under bolt heads or nuts to increase the bearing surface area, or to offer protection so that the nut or bolt can be rotated without distortion of the bearing surface. Flat washers are also used to give tightness to a joint, to prevent leakage, and especially to distribute pressure under the head of a bolt or nut. Dimensional specifications are governed by ASME B18.21.1. USS (United States Standard) flat washers have a larger outer diameter than SAE (Society of Automotive Engineers) flat washers, and can be utilized in nearly any application. ASTM F844 covers the standard specifications for unhardened steel flat washers for general use. Available in zinc plated finish. Zinc plating sacrifices itself, corroding before the base material, offering added corrosion resistance.
