Empilweni yethu, i-CPE ne-PVC ziyasetshenziswa kabanzi. I-polyethylene ene-chlorine iyinto ye-polymer egcwele enokubukeka kwempuphu emhlophe, ayinabo ubuthi futhi ayinambitheki, futhi inokumelana okuhle nesimo sezulu, ukumelana ne-ozone, ukumelana namakhemikhali kanye nokumelana nokuguga. Ukusebenza kahle, inokumelana okuhle kwamafutha, ukubambezeleka komlilo kanye nezakhiwo zombala. Ukuqina okuhle (kusaguquguquka ku--30°C), ukuhambisana okuhle nezinye izinto ze-polymer, kanye nokushisa okuphezulu kokubola. I-polyethylene ene-chlorine iyinto ye-polymer eyenziwe nge-polyethylene ene-high-density (HDPE) ngokusebenzisa ukusabela kokushintsha kwe-chlorination. Ngokwezakhiwo ezahlukene kanye nokusetshenziswa, i-polyethylene ene-chlorine ingahlukaniswa ngezigaba ezimbili: i-polyethylene ene-chlorine (CPE) ye-resin-type kanye ne-polyethylene ene-chlorine (CM) ye-elastomer-type. Ngaphezu kokusetshenziswa yodwa, ama-resin e-thermoplastic angaxutshwa ne-polyvinyl chloride (PVC), i-polyethylene (PE), i-polypropylene (PP), i-polystyrene (PS), i-ABS ngisho ne-polyurethane (PU). Embonini yerabha, i-CPE ingasetshenziswa njengerabha ekhethekile esebenza kahle kakhulu, esezingeni eliphezulu, futhi ingasetshenziswa nerabha ye-ethylene-propylene (EPR), irabha ye-butyl (IIR), irabha ye-nitrile (NBR), i-polyethylene ye-chlorosulfonated (CSM), njll. Kusetshenziswa ezinye izingxube zerabha.
Ngawo-1960, inkampani yaseJalimane iHoechst yaqala ukuthuthukisa ngempumelelo futhi yathola umkhiqizo wezimboni. Izwe lami laqala ukuthuthukisa i-polyethylene ene-chlorine ngasekupheleni kwawo-1970. I-"Aqueous Phase Suspension Synthesis of CPE Technology" yaqala ukuthuthukiswa ngempumelelo yi-Anhui Chemical Industry Research Institute, futhi amadivayisi okukhiqiza angama-500-1000t/a anezikali ezahlukene akhiwe eWuhu, e-Anhui, eTaicang, eJiangsu, naseWeifang, eShandong.
Ukumelana kukawoyela kwe-CPE kujwayelekile, phakathi kwalokho ukumelana kukawoyela we-ASTM No. 1 kanye nowoyela we-ASTM No. 2 kuhle kakhulu, okulingana ne-NBR; ukumelana kukawoyela we-ASTM No. 3 kuhle kakhulu, kungcono kune-CR, okulingana ne-CSM.
I-CPE iqukethe i-chlorine, enezakhiwo ezinhle kakhulu zokuvimbela ilangabi futhi inezici zokusha kanye nokulwa nokuconsa. Ingahlanganiswa ne-antimony-based flame retardant, i-chlorine paraffin, kanye ne-Al(OH)3 ngesilinganiso esifanele ukuthola into evimbela ilangabi enokusebenza okuhle kakhulu kokuvimbela ilangabi kanye nezindleko eziphansi.
I-CPE ayinabo ubuthi, ayinazo izinsimbi ezisindayo kanye ne-PAHS, futhi ihlangabezana ngokugcwele nezidingo zokuvikela imvelo.
I-CPE inokusebenza okuphezulu kokugcwalisa futhi ingenziwa imikhiqizo ehlangabezana nezidingo zokusebenza ezahlukahlukene. I-CPE inokusebenza kahle, i-Mooney viscosity (ML121 1+4) iphakathi kuka-50-100, futhi kunezinhlobo eziningi ongakhetha kuzo.
