Product features:
Internal glue: polyurethane and butyl rubber are used as the main raw materials and special reinforcing agents are added. The color of the finished product is yellow and transparent. It has the characteristics of high wear resistance, high toughness, high pressure resistance and so on. The wear resistance index is 2-3 times that of ordinary sandblasting rubber hose. In the same industry, enjoy the reputation of "wear-resistant king".
Enhanced layer
The sand blasting rubber hose is made of high quality rubbing cloth as the reinforcing layer, with good flexibility and strong bearing capacity.
Steel wire hose blasting using special copper hose braided, work under pressure is 3-4 times the hose cloth, with a high degree of resistance, flex resistance advantages.
Scope of use:
The products are mainly used in all kinds of tunnel engineering, well, tunnel, cavern, slope shotcrete, and have extensive application fields in the fields of hydropower, mining, military and defense.
