Core Sandblast Rubber Hose

Description

Structure:

1. Inner Tube: The inner part of a sandblasting hose is typically made from high-quality, abrasion-resistant rubber that can withstand the high-speed impact of abrasive particles such as sand, steel shot, or grit. The material must be tough to reduce wear and tear.
2. Reinforcement: Around the inner tube, there are layers of fabric or metal reinforcements that provide the strength needed to resist kinking and to withstand the high pressure generated during the blasting process. These reinforcements are often made of materials like nylon, polyester, or steel wire.
3. Outer Cover: The outer layer of the hose is also made of rubber, but with additional properties to resist weathering, ozone, and other environmental factors. It also protects the reinforcement layers from damage.Abrasion Resistance Coefficient:
   • The abrasion resistance coefficient is a measure of the material’s ability to withstand wear. In sandblasting hoses, this is usually rated according to international standards or the manufacturer’s specifications.
   • The coefficient is determined by tests such as the DIN (Deutsche Industrie Norm) abrasion test, which measures the volume loss of the material after a certain number of cycles against an abrasive medium.
   • The lower the volume loss, the higher the abrasion resistance coefficient and the longer the hose will last.
