I-Chlorinated polyethylene (CPE) iyi-polymer egcwele, ukubonakala kwempushana emhlophe, engenabuthi futhi ayinambitheki, inokumelana nesimo sezulu esihle kakhulu, ukumelana ne-ozone, ukumelana namakhemikhali nokumelana nokuguga, ukumelana nowoyela okuhle, ukunqanda ilangabi kanye nezakhiwo zombala.Ukuqina okuhle (kusaguquguquka ku -30℃), kunokuhambisana kahle nezinye izinto ze-polymer, izinga lokushisa eliphezulu lokubola, ukubola kwe-HCl, i-HCl ingakwazi ukugqugquzela ukusabela kwe-dechlorination ye-CPE.
Igama Elisemthethweni: I-Chlorinated Polyethylene, Isifinyezo: I-CPE, I-Chlorinated polyethylene iyimpahla ye-polymer elungiselelwe kusuka ku-high density polyethylene (HDPE) ngokusabela kokushintshwa kwe-chlorination.Ngokwesakhiwo esihlukile nokusetshenziswa, i-polyethylene e-chlorinated ingahlukaniswa ibe yi-resin chlorinated polyethylene (CPE) kanye nohlobo lokunwebeka lwe-chlorinated polyethylene (CM) izigaba ezimbili.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 njengerabha ekhethekile esezingeni eliphezulu, esezingeni eliphezulu, futhi ingahlanganiswa nerabha ye-ethylene propylene (EPR), irabha ye-butyl (IIR), irabha ye-nitrile butadiene (NBR), i-chlorosulfonated polyethylene ( CSM) namanye amarabha.
Isici se-CPE
I-1, i-CPE iwuhlobo lwerabha egcwele, inokumelana okuhle kakhulu nokushisa komoya-mpilo ukuguga, ukuguga kwe-ozone, ukumelana ne-asidi ne-alkali, izakhiwo zamakhemikhali.
2, ukumelana nowoyela kwe-CPE kujwayelekile, futhi ukumelana nowoyela we-ASTM 1 kanye namafutha e-ASTM 2 kuhle kakhulu, okulingana ne-NBR;Ukumelana okuhle kakhulu kuwoyela we-ASTM 3, okungcono kune-CR, futhi kuqhathaniswa ne-CSM.
I-3, i-CPE iqukethe i-chlorine, inokusebenza okuhle kakhulu kwe-flame retardant, futhi inezici zokulwa nokuvuza.Izinto ezibushela ilangabi ezisebenza kahle ekubambeni ilangabi kanye nezindleko eziphansi zingatholwa ngenani elifanele le-antimony flame retardant, upharafini one-chlorinated kanye ne-Al(OH)3.
4. I-CPE ayinabo ubuthi, ayinazo izinsimbi ezisindayo nama-PAH, futhi ihlangabezana ngokugcwele nezidingo zemvelo.
I-5, i-CPE inokusebenza okuphezulu kokugcwalisa, ingalungiselelwa ukuhlangabezana nezidingo ezihlukahlukene zokusebenza ezahlukene zomkhiqizo.I-CPE inokusebenza okuhle kokucubungula futhi i-Mooney viscosity itholakala kumabanga ahlukahlukene phakathi kuka-50-100.
