PVC Lay Flat Hose for Pump Delivery
PVC Lay Flat Hose is made of polyvinyl chloride resin and stabilizer and lubricant. After extrusion, it is first developed and applied for plastic pipes. The PVC Lay Flat Hose has strong corrosion resistance, easy adhesion, low price and hard texture. But because of PVC monomer and additives exudation, it is only suitable for the water supply system with a temperature of less than 45 C. Plastic pipes are used for drainage, waste water, chemicals, heating fluids and coolants, food, ultra pure liquids, mud, gas, compressed air and vacuum systems.
PVC Lay Flat Hose, PVC resin as raw material, is a polar amorphous polymer. Its density is 1.380 g/cm3 and glass transition temperature is 87 C, so it has poor thermal stability and is not easy to process. Can not directly use, must be modified by mixing, adding additives and fillers can be used, and related additives and filler types and different grades, which determines the performance and requirements of PVC materials are not the same, we usually called PVC tube formula strictly speaking, PVC is a modified formula, and PVC can be used only after modification. This class is usually classified as polymer modified material. The modification of polymer materials is mainly focused on the high performance of general plastics, the transformation of single component materials to multi component materials and composites (alloys, blending and compounding), giving the materials functionalization, optimizing performance and price. The modified methods mainly include chemical modification, filling modification, reinforced modification, blending modification and nano composite modification. The basic principle of modification is to give the material a function or improve some performance by adding additives. Therefore, the high level of PVC formula technology determines the high technology and production capacity of a factory.
In general, PVC should be modified to granulate first, and after the formation of particles by screw extruder, the plasticization is more sufficient and the processing is easier, especially the process is the injection product. The screw extruder is one of the most important equipments in plastic molding. It is used for solid conveying, compaction, melting, shearing and mixing extrusion of plastics through external power transmission and heat transfer of external heating elements. Screw extruders play an important role no matter as plasticizing and granulating machines, or molding machines. Strictly speaking, there are special requirements for PVC Lay Flat Hose, PVC modified formula is customized according to customer requirements. There are also copolymerization in the PVC production process, such as vinyl chloride copolymers, PVC blends, and chlorinated PVC.
