The production process of high pressure rubber hose is introduced:
- Use the mixer to mix the inner layer of rubber, a middle layer of rubber, and the outer layer of rubber according to the formula; use the extruder to extrude the inner layer of tubing, wrapped in the coated with a release agent on the soft or hardcore (liquid nitrogen freezing method can also be used without the core).
- The calender was pressed into the middle layer of the rubber sheet, plus the isolation agent was rolled and cut into the required width according to the process requirements.
- Wind or weave copper-plated steel wire or copper-plated steel wire rope on the winding machine or braiding machine with the inner layer of oil pipe containing the core, and at the same time, synchronize the middle layer of rubber sheet with the winding machine or braiding machine to be wound between each two layers of copper-plated steel wire or copper-plated steel wire rope, and tie up at the beginning and at the end of the twisted steel wire (some early winding machines need to pre-stress the copper-plated steel wire for the pre-stressing and sizing treatment).
- Wrap the outer layer of rubber again on the extruder, and then wrap the lead or cloth vulcanized protective layer.
- Vulcanization by means of a vulcanizing tank or salt bath.
- After removing the vulcanized protective layer, pull out the core, buckle on the pipe joints, sampling pressure test.
In short, the manufacture of high pressure rubber hoses using a variety of equipment, raw materials, and complex production processes. However, in recent years plastic or thermoplastic elastomer as the main raw material of high pressure rubber hose production process can be appropriately simplified, but the high price of raw materials, still mainly rubber raw materials.
