Bophelong ba rona, CPE le PVC li sebelisoa haholo le ho feta.Polyethylene ea chlorinated ke ntho e entsoeng ka polymer e nang le ponahalo ea phofo e tšoeu, e se nang chefo ebile e sa latsoehe, 'me e na le khanyetso e ntle ea boemo ba leholimo, khanyetso ea ozone, khanyetso ea lik'hemik'hale le botsofali.Ts'ebetso, e nang le khanyetso e ntle ea oli, ho lieha ha lelakabe le thepa ea mebala.Matla a matle (a ntse a fetoha habonolo ho -30 ° C), ho lumellana hantle le lisebelisoa tse ling tsa polymer, le mocheso o phahameng oa ho bola.Polyethylene ea chlorinated ke ntho e entsoeng ka polymer e entsoeng ka polyethylene e phahameng haholo (HDPE) ka karabelo ea sebaka sa chlorination.Ho latela meaho le ts'ebeliso e fapaneng, polyethylene e hloekisitsoeng e ka aroloa ka mekhahlelo e 'meli: resin-mofuta oa chlorinated polyethylene (CPE) le elastomer-type chlorinated polyethylene (CM).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 sebelisoa le rabara ea ethylene-propylene (EPR), rabara ea butyl (IIR), rabara ea nitrile (NBR), chlorosulfonated polyethylene ( CSM), joalo-joalo Metsoako e meng ea rabara e sebelisoa.
Lilemong tsa bo-1960, k'hamphani ea German Hoechst e ile ea qala ka katleho ho hlahisa le ho hlokomela tlhahiso ea indasteri.naha ea heso e ile ea qala ho hlahisa polyethylene ea chlorinated ho elella bofelong ba lilemo tsa bo-1970."Aqueous Phase Suspension Synthesis of CPE Technology" e qalile ka katleho ke Anhui Chemical Industry Research Institute, 'me lisebelisoa tsa tlhahiso ea 500-1000t / a tse nang le litekanyo tse fapaneng li hahiloe Wuhu, Anhui, Taicang, Jiangsu, le Weifang, Shandong. .
Ho hanyetsa oli ea CPE ke karolelano, eo ho eona ho hanyetsang ASTM No. 1 oli le ASTM No. 2 oli e ntle haholo, e lekanang le NBR;ho hanyetsa ASTM No. 3 oli e ntle haholo, e molemo ho feta CR, e lekanang le CSM.
CPE e na le chlorine, e nang le thepa e ntle ea ho thibela malakabe 'me e na le litšobotsi tsa ho chesa le ho thibela ho rotha.E ka kopanngoa le antimony-based flame retardant, parafine e chlorine, le Al(OH) 3 ka tekanyo e nepahetseng ho fumana thepa e thibelang malakabe e nang le ts'ebetso e babatsehang e thibelang lelakabe le theko e tlaase.
CPE ha e na chefo, ha e na litšepe tse boima le PAHS, 'me e kopana ka botlalo le litlhoko tsa ts'ireletso ea tikoloho.
CPE e na le ts'ebetso e phahameng ea ho tlatsa mme e ka etsoa lihlahisoa tse fihlelang litlhoko tse fapaneng tsa ts'ebetso.CPE e na le ts'ebetso e ntle, viscosity ea Mooney (ML121 1+4) e pakeng tsa 50-100, 'me ho na le limaraka tse ngata tseo u ka khethang ho tsona.
