Description
Technical Field
The invention relates to a UPVC winding pipe, in particular to a UPVC double-plastic lining reinforced winding pipe and a production process thereof.
Background
The UPVC winding pipe is introduced from abroad to equipment production from around 2000 years in China, and production equipment is developed by domestic equipment manufacturers in the same year. The UPVC winding pipe widely used in the current market is divided into two types:
the PVC pipe is formed by spirally winding strips extruded by PVC formula materials (secondary winding molding is needed), the PVC pipe has larger market share, and a large amount of calcium powder (talcum powder) is added into the formula in the production process of each manufacturer for reducing material cost, increasing rigidity and improving strengthAt the same timeIncrease the weight of the product and the brittleness of the product, however, the productTo is coming toThe weight is reduced, thereby the structure of the product is thinned, the comprehensive quality of the product is reduced, the service performance and the service life are reducedThe recycling cycle period of the waste plastics is shortened, and the surrounding environment is polluted;
another type is in PVCWinding ofOn the outer wall of the pipeThen, the product is processedThe rigidity is enhanced by winding and solidifying the glass fiber reinforced plastic with a certain thickness (three times of winding, solidifying and molding are needed), the market share ratio is small, the method has the defects of complex process, heavy pipe material and high cost, the glass fiber reinforced plastic can generate pungent smell in the solidifying process, the two materials are bonded together and are difficult to regenerate and recycle in the future, and the environmental pollution is easily caused.
PP, a thermoplastic resin made by polymerizing propylene. The pipe material is divided into three types of isotactic polypropylene (isotatic polypropylene), atactic polypropylene (atactic polypropylene) and syndiotactic polypropylene (syndiotactic polypropylene) according to the arrangement position of a methyl group, and compared with a metal material used as a lining material of a UPVC (unplasticized polyvinyl chloride) winding pipe, the pipe material made of the PP material is lighter in weight, more excellent in corrosion resistance and longer in service life.
The advantages of the PP material compared to the PVC material are as follows:
1) the density of PP is 0.89-0.91 g/cm3The density of the PVC is 1.38-1.50 g/cm3Therefore, under the same volume, the weight of the PP is only equal to 60 percent of that of the PVC, so that the PP material has the advantages of light weight and capability of saving the material consumption;
2) the elastic modulus of PP is 0.8-10Gpa, the elastic modulus of PVC is 3.14-3.92Gpa, and the higher the elastic modulus is, the higher the rigidity is, the PP can obtain rigidity which is at least 2 times higher than that of PVC, so that the weight can be reduced, and the rigidity of the product can be improved;
3) PP has a longer bending fatigue life (durability) than PVC;
4) PP is more resistant to high temperatures than PVC;
5) the PP hollow pipe can be modified and utilized by adopting a renewable resource material, and the market unit price is slightly lower than that of a UPVC formula material.
