Bohlokoa ba Lapeng - E loketse ho sebelisoa bakeng sa mesebetsi ea lelapa joalo ka ho hlatsoa lijana, ho hloekisa, ho hlokomela batho ba tsofetseng, ho hlophisa lipalesa le tse ling.
Tšireletso ea Sleeve e Melelele - Lisebelisoa tsa PVC tsa boleng bo holimo le tse sa keneleng metsi tse nang le mohlala oa lipalesa karolong e atolositsoeng ea letsoho la liatlana tsena.
Polyvinyl chloride (PVC) ke initiator ea vinyl chloride monomer (VCM) ka peroxide, azo metsoako, joalo-joalo Kapa tlas'a ketso ea leseli le mocheso ho ea ka free radical polymerization reaction mechanism of polymer.The homopolymer of vinyl chloride and the copolymer tsa vinyl chloride li bitsoa vinyl chloride resin.
PVC bakeng sa sebopeho sa amorphous sa phofo e tšoeu, degree ea branched e nyane, letsoalo le lekanyelitsoeng 1.4, mocheso oa phetoho oa khalase oa 77 ~ 90℃, 170℃kapa hoo ho ile ha qala ho bola, ho se tsitse ha mocheso le khanya, ka nako e fetang 100℃kapa letsatsi ka nako e telele, le tla bola le ho hlahisa hydrogen chloride, 'me ka ho eketsehileng jarolla ka ho iketsa catalytic decomposition, bakang discoloration, thepa ea' mele le mechine le tsona li ile tsa oa ka potlako,Ka ts'ebetso, li-stabilizer li tlameha ho ekeletsoa ho ntlafatsa botsitso ba mocheso le leseli.
Boima ba limolek'hule tsa PVC tse hlahisoang ke indasteri hangata li ka ba 50,000 ~ 110,000, ka polydispersity e kholo, 'me boima ba molek'hule bo eketseha ka ho fokotseha ha mocheso oa polymerization; Ha ho ntlha e tsitsitseng ea ho qhibiliha, 80 ~ 85℃ho nolofatsa, 130℃ho boemo ba viscoelastic, 160 ~ 180℃ho fetoha boemo ba phallo ea viscous; E na le thepa e ntle ea mochini, e matla e ka bang 60MPa, matla a tšusumetso a 5 ~ 10kJ/m2; Thepa e ntle haholo ea dielectric.
PVC e kile ea e-ba tlhahiso e kholo ka ho fetisisa lefatšeng ea lipolasetiki tsa morero o akaretsang, tse sebelisoang haholo.E sebelisoa haholo ho thepa ea mohaho, lihlahisoa tsa indasteri, litlhoko tsa letsatsi le letsatsi, letlalo la fatše, tile ea fatše, letlalo la maiketsetso, phala, terata le cable, filimi ea ho paka, botlolo. , thepa e phophomang, thepa ea ho tiisa, fiber joalo-joalo.
