Aiga Taua - Lelei e faʻaoga mo lima i luga o galuega a le fale e pei o le fufuluina o ipu, faʻamamā, tausia o se tagata matua, teu fugalaau ma isi mea.
Puipuiga Lima Umi - Mea maualuga ma le Suavai o le PVC ma mamanu fuga i luga o le lima faʻalautele o nei totigilima
Polyvinyl chloride (PVC) o le initiator o le vinyl chloride monomer (VCM) i peroxyide, azo tuufaatasiga, etc.Po i lalo o le gaioiga o le malamalama ma le vevela e tusa ai ma le free radical polymerization reaction mechanism of polymer.The homopolymer of vinyl chloride ma le copolymer o vinyl chloride ua ta'ua vinyl chloride resins.
PVC mo le fausaga amorphous o le paʻepaʻe paʻepaʻe, tikeri lala e laʻititi, vavalalata 1.4, vevela suiga tioata o 77 ~ 90℃, 170℃pe na amata ona pala, leaga le mautu i le vevela ma le malamalama, i le silia ma le 100℃po o le la mo se taimi umi, o le a decompose ma maua ai le hydrogen chloride, ma atili ai le catalytic decomposition otometi, mafua ai le discoloration, meatotino faaletino ma masini pa'u vave foi, I le faatinoga, e tatau ona faaopoopo stabilizers e faaleleia le mautu vevela ma le malamalama.
O le mamafa mole mole o le PVC gaosia e ala i pisinisi e masani lava i le va o le 50,000 ~ 110,000, faʻatasi ai ma polydispersity tele, ma faʻateleina le mamafa o le mole ma le faʻaitiitia o le vevela polymerization; Leai se mea faʻafefeteina tumau, 80 ~ 85℃e faamalulu, 130℃i tulaga viscoelastic, 160 ~ 180℃e suia i le tulaga tafe viscous; E iai mea faʻainisinia lelei, malosi faʻamalosi e uiga i le 60MPa, malosi malosi o le 5 ~ 10kJ / m2; Lelei mea dielectric.
PVC faʻaaogaina e avea ma gaosiga sili ona tele a le lalolagi o palasitika faʻamoemoe lautele, faʻaaogaina lautele. E faʻaaogaina lautele i mea faufale, oloa gaosi oloa, mea e manaʻomia i aso uma, paʻu fola, fola o le fale, paʻu paʻu, paipa, uaea ma uaea, afifiina ata, fagu. , mea faʻafefe, mea faʻamaufaʻailoga, fiber ma isi.
