Ezimpilweni zethu, i-CPE ne-PVC zisetshenziswa kabanzi. I-Chlorinated polyethylene iyi-saturated polymer material ebukeka njengempushana emhlophe, ayinabo ubuthi futhi ayinambitheki, futhi inokumelana nesimo sezulu esihle kakhulu, ukumelana ne-ozone, ukumelana namakhemikhali kanye nokumelana nokuguga. Ukusebenza, nokumelana nowoyela okuhle, ukuncipha komlilo kanye nezakhiwo zombala. Ukuqina okuhle (kusaguquguquka ku -30°C), ukuhambisana kahle nezinye izinto ze-polymer, nezinga lokushisa eliphezulu lokubola. I-Chlorinated polyethylene i-polymer material eyenziwe nge-high-density polyethylene (HDPE) ngokusebenzisa ukusabela kokushintshwa kwe-chlorination. Ngokwezakhiwo ezihlukene kanye nokusetshenziswa, i-polyethylene e-chlorinated ingahlukaniswa ngezigaba ezimbili: i-resin-type chlorinated polyethylene (CPE) kanye ne-elastomer-type chlorinated polyethylene (CM). Ngaphezu kokusetshenziswa yedwa, ama-thermoplastic resins angabuye ahlanganiswe ne-polyvinyl chloride (PVC), i-polyethylene (PE), i-polypropylene (PP), i-polystyrene (PS), i-ABS kanye ne-polyurethane (PU). Embonini yenjoloba, i-CPE ingasetshenziswa njengenjoloba ekhethekile esezingeni eliphezulu, esezingeni eliphakeme, futhi ingasetshenziswa nerabha ye-ethylene-propylene (EPR), irabha ye-butyl (IIR), irabha ye-nitrile (NBR), i-chlorosulfonated polyethylene ( CSM), njll. Okunye ukuxutshwa kwenjoloba kuyasetshenziswa.
Ngawo-1960, inkampani yaseJalimane i-Hoechst yaqala yathuthukisa futhi yaqaphela ukukhiqizwa kwezimboni. izwe lami laqala ukuthuthukisa i-polyethylene ene-chlorine ngasekupheleni kwawo-1970. I-"Aqueous Phase Suspension Synthesis of CPE Technology" yasungulwa ngempumelelo yi-Anhui Chemical Industry Research Institute, futhi kwakhiwe imishini yokukhiqiza engu-500-1000t/a enezikali ezihlukene eWuhu, Anhui, Taicang, Jiangsu, naseWeifang, eShandong. .
Ukumelana kwamafutha kwe-CPE kuyisilinganiso, phakathi kwalokho ukumelana nowoyela we-ASTM No. 1 kanye namafutha e-ASTM No. 2 kuhle kakhulu, okulingana ne-NBR; ukumelana nowoyela we-ASTM No. 3 kuhle kakhulu, kungcono kune-CR, okulingana ne-CSM.
I-CPE iqukethe i-chlorine, enezici ezinhle kakhulu zokunqanda amalangabi futhi enezici zokuvutha nokulwa nokuconsa. Ingahlanganiswa ne-antimony-based flame retardant, upharafini okloriniwe, kanye ne-Al(OH)3 ngokwesilinganiso esifanele ukuze kutholwe into ebamba ilangabi esebenza kahle kakhulu ebamba ilangabi kanye nezindleko eziphansi.
I-CPE ayinabo ubuthi, ayinazo izinsimbi ezisindayo kanye ne-PAHS, futhi ihlangabezana ngokugcwele nezimfuneko zokuvikelwa kwemvelo.
I-CPE inokusebenza kokugcwalisa okuphezulu futhi ingenziwa ibe yimikhiqizo ehlangabezana nezidingo ezahlukahlukene zokusebenza. I-CPE inokucutshungulwa okuhle, i-Mooney viscosity (ML121 1+4) iphakathi kuka-50-100, futhi kunamabanga amaningi ongakhetha kuwo.
