The so-called hydraulic hose refers to the high-pressure hose with steel wire braiding or steel wire winding structure. It has particularly harsh requirements on the type and index of the rubber material used, especially the inner hose. So whether reclaimed rubber can be used in the production of hydraulic hose as a new raw material to reduce the cost of various rubber products instead of raw rubber, what kinds of reclaimed rubber can better reduce the production cost of hydraulic hose while ensuring the quality and service life of hydraulic hose products?

1, "touch" texture is delicate, whether the particles are uniform. At present, there are mainly white, gray and green colors on the market. Under normal circumstances, recycled plastics cannot be white, so consumers often think that white is good. In fact, this view is rather one-sided. With the update of technology, color is not the standard to distinguish the quality of PP pipe. The quality of the tube cannot solve the problem. Touch it, and the rough particles are likely to be mixed with other impurities.

What should be paid attention to when using pp pipe construction? As a kind of special plastic pipe, because of its perfect performance, it is mostly used in building cold and hot water discharge and switching system in life. So what should we pay attention to in the process of using pp pipe?

PP pipes should be stacked horizontally on the flat ground, bending pipes should be avoided, stacking height should not exceed 1.5m, pipe fittings should be stacked layer by layer, should not be stacked too high. PP pipes and fittings shall be placed in well-ventilated warehouses or simple sheds, and shall not be stored in the open air to prevent direct sunlight. Pay attention to fire safety and the distance from heat source shall not be less than 1m. Pipes and fittings shall be handled with care to avoid oil pollution. Violent impact is strictly prohibited. It is strictly prohibited to touch, throw, drop, roll and drag with sharp objects.

EPDM rubber has excellent high and low temperature resistance and aging resistance, and can maintain good service performance for a long time under specified low temperature conditions when it is used to produce cold-resistant hose. EPDM reclaimed rubber is an ideal substitute material for EPDM rubber. When it is used with EPDM rubber to produce cold-resistant hose, the purpose of ensuring quality and reducing cost can be achieved through reasonable formula design. So what should be paid attention to when designing the formula of rubber hose using EPDM/reclaimed rubber to produce cold resistant rubber hose?
