Description
Technical field
The present invention relates to the preparation process of water-band, particularly relate to the preparation process for fire-extinguisher water hose, F16L11 classification can be belonged to according to IPC international classifiation table.
Background technique
Fire-extinguisher water hose is used to the flexible pipe transporting the anti-flaming liquid such as high pressure water or foam.Traditional fire-extinguisher water hose is generally the braid that plastic flat fiber, synthetic fiber or yarn, flax braided fabric etc. are formed by weaving according to longitude and latitude is that main body realizes the withstand voltage framework main of water-band, but braid has space cannot stop moisture to spill, then at braid internal layer lining material to realize water-proof performance.In addition, in order to protect braid not frayed, some fire-extinguisher water hoses also at the additional one deck of organization level skin as the external coating of wear resistant resin material, this external coating has also been held concurrently withstand voltage with effect that is against leakage.Lining material mainly chooses the material meeting high pressure resistant, oil resistant, the feature such as corrosion-resistant, lightweight, soft.Lining material can be rubber, latex, plastic-coated, polyurethane etc.Choosing of external coating is based on weatherability and wear resistance, can use neoprene, acrylic rubber, chlorosulfonation rubber, lactoprene etc., also uses PVC＝polyvinyl chloride resin.
The manufacture method of existing fire-extinguisher water hose mainly contains 2 kinds: the first is that lining material, braid and external coating are combined into water-band wall, and then overlap joint forms water-band pipeline.The second directly plastic flat fiber, synthetic fiber or yarn, flax braided fabric solid is compiled into water-band pipe, then the internal lining pipe manufactured and outer cladding pipe coated with adhesive is inserted in bonding and fixedly forms.First method manufacture is simple, but anti-leakage and resistance to pressure limited.Second method manufacture is relatively difficult, but anti-leakage and resistance to pressure are all higher.
The fire-extinguisher water hose of existing natural rubber liner has mature production technology, the advantage that with low cost, ductility is good, but still comes with some shortcomings: insufficient strength, and wear resistance is not good, and oil resistant, shortcoming that corrosion resistance is inadequate.In addition, the sulfuration of the elastometric lining of the fire-extinguisher water hose of the elastometric lining of the 2nd kind of manufacturing process carries out after being inserted in braid, not convenient in operation, and degree of cure is also unfavorable for controlling.
