Wear resistant sand blasting hose is a kind of material conveying pipe. Common black, sub yellow or transparent; Most of them are wrapped by external rubber packing belt, and steel wire is often used between internal and external rubber to apply to negative pressure working condition. It is mainly used for the transportation of particles, gravel, cement, quicksand, concrete, gypsum and other fluid containing solid particles. Dalian sandblasting process introduces the wear-resistant rubber hose of sandblasting gun barrel, which is suitable for all kinds of tunnel engineering, shaft and tunnel, cavern and other engineering operations. For common materials, wear-resistant materials are usually used for the inner and outer rubber of sand blasting pipe, mostly NBR (acrylonitrile butadiene copolymer), SBR (oil filled styrene butadiene rubber), or para rubber (clover rubber) with better performance of imported hose. The sand blasting pipe is generally divided into light sand blasting pipe and heavy sand blasting pipe according to the working conditions and the loss degree of material particles to the conveying medium. The spiral steel wire will make it suitable for the negative pressure environment. It is usually used in environments such as ship sand blasting and quicksand operation; The common inner rubber is made of wear-resistant NBR (natural rubber) material, and the outer rubber is wrapped with composite rubber.
