Chlorinated polyethylene (CPE) bụ ihe polymer juru eju, ọdịdị nke ntụ ntụ na-acha ọcha, nke na-adịghị egbu egbu na nke na-enweghị ụtọ, nke nwere oke ihu igwe dị mma, nguzogide ozone, nguzogide kemịkalụ na nguzogide ịka nká, nwere ezigbo mmanu mmanu, ire ọkụ na agba agba.Ezi ike (ka na-agbanwe na -30 ℃), nwere ezigbo ndakọrịta na ihe ndị ọzọ polymer, elu decomposition okpomọkụ, decomposition nke HCl, HCl nwere ike catalyze dechlorination mmeghachi omume nke CPE.
Aha Offical: Chlorinated Polyethylene, Abbreviation: CPE, Chlorinated polyethylene bụ ihe polymer a kwadebere site na nnukwu njupụta polyethylene (HDPE) site na mmeghachi omume nnọchi chlorination.Dị ka usoro na ojiji dị iche iche si dị, enwere ike kewaa polyethylene chlorinated gaa na resin chlorinated polyethylene (CPE) na ụdị elastic chlorinated polyethylene (CM) ụzọ abụọ.Na mgbakwunye na iji naanị ya, a pụkwara ịgwakọta resin thermoplastic na polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS na ọbụna polyurethane (PU).N'ime ụlọ ọrụ rọba, enwere ike iji CPE mee ihe dị ka ihe na-arụ ọrụ dị elu, rọba pụrụ iche dị elu, ma nwee ike jikọta ya na ethylene propylene roba (EPR), butyl rubber (IIR), nitrile butadiene roba (NBR), chlorosulfonated polyethylene ( CSM) na rubbers ndị ọzọ.
Njirimara CPE
1, CPE bụ ụdị rọba juputara, nwere ezigbo okpomọkụ na-eguzogide oxygen ịka nká, ozone ịka nká, acid na alkali eguzogide, chemical Njirimara.
2, mmanụ na-eguzogide CPE bụ n'ozuzu, na iguzogide mmanụ ASTM 1 na mmanụ ASTM 2 dị mma, nke kwekọrọ na NBR;Nnukwu iguzogide mmanụ ASTM 3, dị mma karịa CR, yana atụnyere CSM.
3, CPE nwere chlorine, nwere ezigbo ọkụ retardant arụmọrụ, na nwere combustion mgbochi ntapu àgwà.Enwere ike nweta ihe na-eme ka ire ọkụ na-arụ ọrụ nke ọma yana ọnụ ala dị ala site na nha kwesịrị ekwesị nke antimony flame retardant, chlorinated paraffin na Al(OH)3.
4. CPE adịghị egbu egbu, enweghị ọla dị arọ na PAH, ma na-ezute ihe ndị chọrọ gburugburu ebe obibi.
5, CPE nwere arụmọrụ njuputa dị elu, enwere ike ịdị njikere izute ụdị ọrụ dị iche iche chọrọ nke ngwaahịa ahụ.CPE nwere ezigbo nhazi arụmọrụ yana Mooney viscosity dị na ọkwa dị iche iche n'etiti 50-100.
