pvc resin mo paipa, PVC resin mo talaaga,
O le Polyvinyl chloride (PVC) o le amataga lea o peroxides ma azo fa'afefiloi i le vinyl chloride monomer (VCM).Pe i lalo o le gaioiga o le malamalama ma le vevela e tusa ai ma le faiga o le free radical polymerization polymerization polymer.Vinyl chloride homopolymer ma vinyl chloride copolymer e taʻua o le vinyl chloride resin.
O le PVC sa masani ona avea ma palasitika sili ona tele i le lalolagi ma sa faʻaaogaina lautele.E faʻaaogaina lautele i mea faufale, oloa gaosi oloa, mea e manaʻomia i aso taʻitasi, paʻu fola, piliki fola, paʻu faʻapitoa, paipa, uaea ma uaea, afifiina ata, fagu, mea faʻafefe, mea faʻamaufaʻailoga, fiber ma isi.O lona faʻaoga autu o PVC faʻamatalaga, paipa PVC, ata tifaga PVC, PVCPVC mea faigata ma ipu, PVC oloa vaivai lautele, mea faʻapipiʻi PVC, laupapa laupapa PVC ma fola, oloa faʻatau PVC, oloa faʻapipiʻi PVC, oloa foam PVC, pepa manino PVC, ma isi. .
PVC faʻatasi ai ma mea faʻainisinia sili ona lelei, vailaʻau vailaʻau e pei o le teteʻe atu i le acid ma le alkali corrosion, natura mai le faʻaumatiaina e le tagata lava ia o le afi, faʻaitiitia le vevela faʻafefe, faʻasao vevela leo faʻaitiitia leo, oloa o le puipuiga o le siosiomaga, e mafai ona avea ma foliga lelei, e pei o le suiga faaletino ma vailaau ua avea o se mea taua o le fale lanu meamata, maketi fausia inisinia, i le afe, e pei ona iloa ma iloa e le toatele o tagata.I le taimi nei, o le vaega o zhongtai o le muamua, le tolu pito i luga o le lalolagi i totonu o le fale gaosi oloa PVC, ua fausia le fua o le gaosiga faaletausaga o le 2.3 miliona tone o le polyvinyl chloride (PVC) resin, faʻamalosia malosi le faʻaogaina o le PVC oloa maualuga i mea uma. savali o le olaga, o le atinaʻe lanu meamata a le atunuu ma le itu tuʻuina atu e faʻatino ma faʻataunuʻuina le toe fuataʻiga, o se atinaʻe soifua maloloina umi foʻi o le matafaioi a le alamanuia ma le amo.O lenei pepa o loʻo faʻaalia ai le PVC mai itu e lima, e pei o le folasaga, faʻavasegaina, faʻasologa faʻasologa, suiga ma le faʻaogaina.
