Description
Technical field
The present invention relates to a kind of water tap, especially relate to double-layer plastic water channel assembly of a kind of water tap and preparation method thereof.
Background technique
Heat-proof polythene (PE-RT) resin by the exploitation of Tao Shi (DOW) chemical company, began to be applied to the production of pipeline the earliest before more than 20 year.Heat-proof polythene (PE-RT) resin is the polymer that is got by modification by copolymerization by octene and ethene, optimized position and the density of octene copolymer monomer on main chain by Molecular Structure Design, thereby make the PE-RT material keep the good low-temperature resistant and shock resistant performance of conventional polyethylene, give the hydrostatic intensity of PE-RT material excellence simultaneously.The PE-RT material does not need complicated crosslinking process, but has therefore kept the heat sealability of hypocrystalline TPO, can adopt connecting of all welding technique.Tao Shi (DOW) chemical company researchs and develops out PE-RT DOWLEX*2388DOW of new generation by U.S. NSF authentication.Being applied in the drinking-water aspect finishes safe.
The advantage of PE-RT tubing is as follows:
1) density is little, light weight.
2) health can not polluted the medium of being carried.
3) internal surface is smooth, non-scaling, breed bacteria not, can Secure Application in fields such as potable water conveyings.Non-scaling, hydraulic characteristic is good.
4) chemically stable has good corrosion resistance to general acid-base material, and chemical resistance is good, non-corrosive, and long service life is 70 ℃ in operating temperature, pressure is under the 0.4MPa condition, can use safely more than 50 years.
5) thermal conductivity is little, and surperficial condensation is few.
6) hydrostatic intensity height has excellent internal pressure-resistant level.
7) need not crosslinked, can fusion weld, connect reliable quick.
8) Green Product, recyclable utilization again.
At present, domestic just with PE-RT material tubing, also do not use it for the report of water tap water channel assembly.
At present, water tap water channel assembly mainly adopts metallic copper, plastics (interpolation glass fibre) material, these materials have been grown and will have been produced pollution to water quality service time, can slowly be dissolved in water quality as the lead in the copper, and the fiber in the plastics also can be dissolved in the water water quality is produced the contamination hazard health, unfriendly to environment simultaneously, and the PE-RT material obtains U.S. NSF authentication, reaches 50 years working life, is a kind of ep-type material.
Altogether molding and forming is multiple polymers to be injected in succession the technology in the mould in the molding and forming course of working.Polymer should make and contact with each other and do not flow into each other.The composite material that obtains can be that lasting maybe might separating is used for regeneration.
Chinese patent CN2846938 discloses a kind of composite structure water tap that uses metal and plastic or other material, comprise a body and a clad, this body engages institute by a plurality of metal assemblies such as a cold water road, a hot water road, a water outlet and a valve chamber and constitutes, one end of this cold water road, this hot water road and this water outlet is communicated with this valve chamber, the other end of this cold water road, this hot water road and this water outlet forms the opening that makes current logical at this composite structure water tap respectively, first metal parts at least in this cold water road, this hot water road, this water outlet and this valve chamber; After body engagement is finished the plastic packets coating is coated on body exterior, makes the composite structure water tap.
Chinese patent CN201651500U discloses a kind of composite water faucet subject, described tap main body comprises that inner lead, obturator and shell form, inner lead has water inlet and osculum, end at water inlet and osculum is equipped with threaded insert, described obturator is that cement or lime or gypsum are made, and described shell is that plastic materials is made.The tap main body structure is divided into three layers, comprises inner lead, obturator and shell, three layers are adopted three secondary mould manufacturings, and it is raw material that inner lead adopts plastics, through injection mould molding and forming, inner wall smooths such as water inlet, osculum; It is raw material that obturator adopts cement or gypsum or lime, through watering the injection molding form; Shell adopts plastics, by molding and forming.Whole tap main body has been saved a large amount of copper materials, reduces cost, and benefit is very remarkable; Improve processing conditions such as existing founding, sand removal, polishing, overcome workshop and environmental pollution, improve workers ' health, have obvious improvement, case surface is handled easily, helps vacuum coating.
