Wear resistant hose Has many uses, Abrasion resistant sand blasting hose It is mainly used to transport some sharp and sharp solids, such as river sand, cement ash, quartz sand, sand blasting machine steel shot for rust removal, etc. Wear resistant hose can also be used for river dredging, sand taking, etc Sandblasting hose What are the characteristics of wear-resistant hose? And ordinary wear-resistant hose and wear-resistant Sand blasting hose price What's the difference?

Wear resistant rubber hose is a special kind of rubber hose, which is also the general name of various rubber hoses with wear resistance. Wear resistant sand blasting hose is a kind of wear resistant rubber hose, which is mainly used to spray quartz sand, steel shot and other materials, and is connected with sand blasting machine to handle ship rust removal and other industries. We all know that the quartz sand particles are very small, and the edges and corners are very sharp, which requires a large flow rate of quartz sand and steel shot. This requires that the wear resistance of wear-resistant hose or wear-resistant sandblasting hose must be very good to meet the requirements. So how to achieve the wear-resistant sandblasting hose? Now let's talk about the characteristics of wear-resistant sand blasting hose.

Structure of wear-resistant sand blasting hose

It is mainly composed of an inner rubber layer made of polyurethane or butyl rubber, a steel wire braid or fiber reinforced layer, and an outer rubber layer made of UV resistant and anti-aging butadiene styrene rubber. The composition of the structure is the same as that of acid and alkali resistant hose and steam hose, as long as the materials are different. The connection method can adopt the characteristics of hammering the wear-resistant sand blasting hose of Yuwang wear-resistant hose

1、 High wear resistance,. It is made of polyurethane or butyl rubber through vulcanization. The abrasion rate shall not be greater than 0.2g/m2. The service life is more than three times that of similar products.

2、 High pressure resistance and good flexibility. The steel wire braid reinforcement layer or cord fiber reinforcement layer can withstand the working pressure of 6 MPa, and the large burst pressure can reach more than 12 MPa. The wear-resistant sand blasting hose has high strength and good flexibility, which can adapt to the harsh environment such as tunnel, high temperature and high wear.

Wear resistant hose Abrasion resistant sand blasting hose Technical indicators of

1. The tensile strength of the inner rubber layer is greater than 10 MPa, and the tensile strength of the outer rubber layer is greater than 6 MPa

2. The tensile elongation is more than 320%. The higher the rubber content of the inner and outer rubber of the wear-resistant sandblasting hose, the greater the tensile elongation, which indicates that the quality of the wear-resistant hose is better

3. The tensile change rate shall not be greater than 25% under the test condition of 70 ℃/72h in hot air

4. The adhesion strength between layers KN/M is not less than 3.05, and the wear rate is not more than 0.2g/m2
