      Rubber clip cloth

      release time:2023-04-21publisher:

      What is rubber clip cloth?

      Rubber clip cloth is also a kind of rubber diaphragm, its structure is a kind of high wear-resistant oil seal used in shield mechanical cylinder. The difference between it and ordinary oil seals is that one layer or multiple layers of canvas are sandwiched between the rubber components of oil seals, which greatly improves the wear resistance of oil seals. Usually through molding production, the rubber and cloth surface is pressed together, so that the production of the diaphragm has stronger tear resistance, to extend the service life of the characteristics. Rubber diaphragm as an indispensable part of the pump valve industry accessories.


      Characteristics of rubber clip cloth

      1. Can develop a variety of large, small, thick, thin cloth diaphragm.

      2 clip cloth compressive intensity, according to the demand, the use of suitable adhesive, cloth bonding forming.

      3. Rubber material includes NBR, EPDM, FDA, CR, NR, SILICONE, FKM, etc.

      4. Fiber cloth, nylon, Dacron, cotton canvas, stretchable cloth with a variety of warp and weft yarns.

      5. Uniform thickness and good flatness, flatness tolerance can reach ± 0.015mm.

      6. Rubber cloth gasket has good fuel resistance and oil resistance.

      7. Rubber cloth gasket has excellent vibration and fatigue resistance.

      8. The rubber clip cloth has good endurance, including 0.3mm products, which can withstand pressure up to 10kg.


      Classification of rubber clip cloth

      1, according to the structure is also divided into pure rubber type and clip fabric (cloth) type.


      2, according to the shape is divided into round type, square type, plane stamping type.


      3, according to the material can be divided into natural glue NR, nitrile glue NBR, silicone VQM, ternary glue EPDM, fluorine glue FPM/VITTON, etc.


      4, the use of environment can be divided into water resistance, oil resistance, acid and alkali resistance, toluene/propane resistance, natural gas, oil/gasoline (ethanol gasoline) and other solvents.



      Rubber clip cloth in the production of things to pay attention to

      1. Key technology

      Rubber clip cloth can be divided into full clip cloth seals and partial clip cloth seals, different types of clip cloth seals have certain differences in the way of loading. The manufacture of adhesive cloth products is particularly important, which mainly includes the manufacture of adhesive cloth dipping, coating or rubbing, adhesive cloth rubbing and sandwiching semi-finished products.

      2. Rubber clip cloth rubbing preparation

      During preparation, cylindric equipment is generally used. The recycled rubber mix is mixed into a solvent and then stirred into a thick semi-fluid paste in the equipment. Rubber rubbing is recommended in the equipment containing high precision roller, scraping plate, rubber plate drying device, usually the distance between the roller and the scraper is controlled between 0.3-0.4mm, to the thickness of rubber. In the process of adhesive preparation, it is necessary to use a thickness meter to check the thickness of adhesive cloth in time.

      3. Vulcanization of rubber clip cloth

      The rubber clip cloth is generally carried out in the plate vulcanizing machine or injection vulcanizing machine, and the choice of molding, injection pressing or injection molding is more common. When rubber clip cloth produces full clip cloth seals, the preformed parts can be vulcanized directly; The vulcanization molding of some clip sealing parts prepared by recycled rubber is generally done in the upper mold with rubber fiber preforming parts, the lower mold with rubber fiber forming parts, and then loaded with rubber billet after vulcanization. The vulcanization molding of the reclaimed rubber sealing parts can also be carried out in the injection vulcanization machine, and the automatic operation of the mold closing, vacuuming and opening is realized. When necessary, the second stage vulcanization is needed. The rubber clip cloth needs to be trimmed after it is made, and the whole clip cloth seal can be washed away by a punch. There is no need to trim the flangeless structure part of some cloth seals, and the rubber part needs to be trimmed by cutting method.
