Flexible rubber joint processing technology and requirements

Flexible rubber joint processing technology and requirements
The bendable rubber joint round ball is composed of a rubber tube through the inner viscose, raising layer with double-scraped acrylic cord fabric, and the outer rubber layer redeemed. Small diameter round ball contains stainless steel wire structure reinforcement to enhance its high pressure resistance actual effect. Because the inner layer of rubber is directly touching with the pipeline commodity circulation material, so the flexural rubber joint design scheme is very high requirements for the inner layer of rubber, are applicable to a very demanding range of locations. There is a good adaptability to transport substances, such as oil pipeline hose provisions of solubility resistance, chemical plant hose provisions of corrosion resistance, fine sand hose provisions of abrasion resistance, food hose provisions ~, no smell. First of all, the inner layer of rubber hose needs to have a good density, especially for transporting gas and high pressure hose. The next requirement is that the inner layer of rubber hose has good adaptability to the transported substances, such as oil pipeline hose, chemical plant hose, chemical plant hose, sand hose, sand hose, food hose, food hose, and odorless.
Flexible rubber joints have a certain elasticity, flexibility, temperature resistance. Flexible rubber joint processing process requirements, flexible rubber joint and other components vulcanization rate pairing, that is, close to the outer rubber, but a little slower than the inner layer of rubber. After the viscose also has to be integrated into the production processability requirements, such as semi-finished products processed with sufficient stiffness, small expansion and contraction, press out, die-casting surface finish, easy to form. Flexible rubber joint product formulation key point rubber type selection with natural rubber and nitrile rubber-based, or natural rubber, nitrile rubber, rubber and with; can also be used rubber and plastic products blended, while the application of the appropriate amount of recycled rubber. Industrial areas have bendable rubber joints, the general rate of rubber content is 25-30 percent. Than the vulcanization management system generally uses sulfur and vulcanization accelerator traditional vulcanization management system. The dose of sulfur is 1.5~2.5 parts, and the vulcanization accelerator is better with thiazoles and their sulfonamides.
