These details need attention when mixing high pressure hoses
 
    The use of high-pressure hoses is becoming more and more widespread, so do you know what problems you need to pay attention to when using high-pressure hoses? Let us ask the professional and technical personnel of high-pressure hose manufacturers to analyze it for us:
    1. Use a kneader to mix the inner, middle and outer layers of the high-pressure hose according to the formula. Use an extruder to extrude the inner tubing and cover it with a soft or hard core coated with a release agent. (The liquid nitrogen freezing method can also be used without a core)
    2. The calender is pressed into a high-pressure rubber tube middle-layer rubber sheet, which is rolled up with a release agent and cut into a specified width according to the process requirements.
    3. Wrap the inner tubing containing the core on the winding machine or braiding machine with copper-plated steel wire or copper-plated steel wire rope. At the same time, the middle-layer rubber sheet is wound around the two layers of copper-plated steel wire or copper-plated steel wire simultaneously , The winding wire is tied at the beginning and end (some early winding machines need to pre-stress the copper-plated steel wire in advance)
    4. Cover the extruder with an outer layer of rubber again, and then wrap the lead or cloth vulcanization protective layer and vulcanize it through a vulcanization tank or a salt bath.
    5. Remove the vulcanization protective layer later, withdraw the tube core, crimp the upper tube joint, and sample the sample for inspection.
