PVC RESIN MO UEA
PVC RESIN MO UIGA,
PVC Uaea Fa'atasi, PVC Cable Raw Material, PVC mo uaea eletise, PVC resin mo le insulation uaea,
PVC ona e lelei le tino, vailaau, eletise, afi retardant faatinoga, i le 1930s ma le 40s, na amata ona faaaoga e tagata ese le PVC malu e pei o mea insulation mo uaea, o le atinae ma le faaaogaina o mea uaea PVC i lo tatou atunuu na amata i le 1950s.Faʻatasi ai ma le faʻaleleia atili o le gaosiga o le PVC resin, plasticizer ma mea faʻapipiʻi faʻapisinisi ma le faʻalauiloaina ma le faʻaogaina o ituaiga fou, o loʻo i ai i le pisinisi uaea se oso maualuga.
I le 21st seneturi, faatasi ai ma le faʻalauteleina o le faʻalauiloaina o le siosiomaga o tagata ma le gauai atu o tagata i lo latou lava soifua maloloina, o mataupu tau le siosiomaga ua avea ma taulaiga o tagata soifua.Le tele o atunuu, itulagi ma faʻalapotopotoga ua faʻatulagaina tulaga maʻoti ma tulafono faatonutonu e faʻatapulaʻa ai le faʻaogaina o mea leaga, aemaise lava tulafono RolS ma REACH.Vaʻavaʻai mo auala fou ma faiga fou, faʻaleleia le faʻaogaina o punaoa, faʻafetaui i manaʻoga o tulafono ma tulafono faatonutonu mo le puipuiga o le siosiomaga, puipuiga o le siosiomaga o mea PVC cable na tulaʻi mai i le taimi nei, ma vave ona avea ma se tasi o autu o le atinaʻeina o mea faʻapipiʻi PVC. .
O le faʻateleina o suiga ma le faʻalauteleina o le maketi o manaʻoga mo uaea ma uaea (ua taʻua o le uaea), faʻapea foʻi ma le suʻesuʻeina loloto o faʻaopoopoga fou eseese (e pei o mea faʻapipiʻi mumu, faʻafefe asu), faʻalauteleina le faʻalauiloaina ma le faʻaogaina o mea fou. tekinolosi, mea fou ma oloa fou o mea PVC.I le tele o mea faʻaola (e pei o le palasitika, paʻu) faʻaaogaina i totonu o pisinisi uaea, o le aofaʻi o mea faʻapipiʻi PVC o le mea muamua lea i totonu o lo tatou atunuu.
O le thermoplastic high-molecular polymer na faia e le polymerization taofia o le vinyl chloride monomer.Ole fua ole mole :- (CH2 – CHCl) n – (N: tikeri o le polymerization, N= 590 ~ 1500).O le mea sili ona fa'aaogaina i le gaosiga o palasitika.E lelei le mautu kemikolo, corrosion tetee ma vai tetee.
