Chlorinated polyethylene (CPE) ke thepa ea polymer e tletseng, ponahalo ea phofo e tšoeu, e se nang chefo le e sa latsoeheng, e nang le khanyetso e ntle ea boemo ba leholimo, khanyetso ea ozone, khanyetso ea lik'hemik'hale le ho tsofala ha botsofali, e nang le ho hanyetsa oli e ntle, ho thibela lelakabe le mebala.Matla a matle (a ntse a tenyetseha ho -30 ℃), a lumellana hantle le lisebelisoa tse ling tsa polymer, mocheso o phahameng oa ho bola, ho bola ha HCl, HCl e ka susumetsa karabelo ea dechlorination ea CPE.
Lebitso la Molao: Polyethylene ea Chlorinated, Kgutsufatso: CPE, Chlorinated polyethylene ke ntho e entsoeng ka polymer e lokisitsoeng ho tloha polyethylene e phahameng ea "high density" (HDPE) ka chlorination substitution reaction.Ho ea ka sebopeho le ts'ebeliso e fapaneng, polyethylene ea chlorinated e ka aroloa ka resin chlorinated polyethylene (CPE) le mofuta oa elastic chlorinated polyethylene (CM) mekhahlelo e 'meli.Ntle le ho sebelisoa feela, li-resin tsa thermoplastic li ka boela tsa kopanngoa le polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS esita le polyurethane (PU).Indastering ea rabara, CPE e ka sebelisoa e le rabara e khethehileng ea boleng bo phahameng, ea boleng bo phahameng, hape e ka kopanngoa le rabara ea ethylene propylene (EPR), rabara ea butyl (IIR), rabara ea nitrile butadiene (NBR), chlorosulfonated polyethylene ( CSM) le liraba tse ling.
Setšoantšo sa CPE
1, CPE ke mofuta oa rabara e tletseng, e na le botsofali bo botle ba mocheso o thibelang oksijene, botsofali ba ozone, acid le alkali resistance, lik'hemik'hale.
2, khanyetso ea oli ea CPE e tloaelehile, 'me ho hanyetsa oli ea ASTM 1 le oli ea ASTM 2 e ntle haholo, e lekanang le NBR;Khanyetso e ntle ho ASTM 3 oli, e betere ho feta CR, mme e bapisoa le CSM.
3, CPE e na le chlorine, e na le ts'ebetso e ntle haholo e thibelang lelakabe, 'me e na le litšobotsi tse thibelang ho rotha ha mollo.Thepa e thibelang lelakabe e nang le ts'ebetso e ntle e thibelang lelakabe le theko e tlase e ka fumanoa ka karolo e nepahetseng ea sehlaseli sa antimone, parafine e chlorine le Al(OH)3.
4. CPE ha e na chefo, ha e na litšepe tse boima le li-PAH, 'me e finyella litlhoko tsa tikoloho ka botlalo.
5, CPE e na le ts'ebetso e phahameng ea ho tlatsa, e ka itokisetsa ho fihlela litlhoko tse fapaneng tse fapaneng tsa ts'ebetso ea sehlahisoa.CPE e na le ts'ebetso e ntle ea ts'ebetso le viscosity ea Mooney e fumaneha ka mefuta e fapaneng ea limaraka lipakeng tsa 50-100.
