Ndị na-emepụta CPE Polyethylene a kpụchara akpụcha
Onye nchịkọta akụkọ nke onye na-emepụta ihe na-egbochi ịka nká ga-egosi gị okwu mmalite dị mkpa gbasara onye na-emepụta ihe na-eme ka polyethylene dị ọcha. Polyethylene dị ọcha (CPE) bụ ngwaahịa a na-eji eme ihe na kemịkalụ. Ọtụtụ mmadụ amaghị maka vinyl chloride chloride. Ghọta, okwu Bekee nke polyethylene dị ọcha bụ: CPE ma ọ bụ cm, polyethylene dị ọcha (CPE) bụ ihe polymer jupụtara, ọdịdị ya bụ ntụ ọcha, ọ naghị egbu egbu ma na-enweghị ụtọ, nwere ezigbo iguzogide ihu igwe, iguzogide ozone, iguzogide kemịkalụ na iguzogide ịka nká, ezigbo iguzogide mmanụ, mbelata ire ọkụ na ihe nchebe ìhè. Ezi ike (ka na-agbanwe agbanwe na -30°C), ezigbo ndakọrịta na ihe ndị ọzọ na-eme ka polima dị ọcha, okpomọkụ dị elu nke mmebi, mmebi nke HCl, HCl nwere ike ime ka mmeghachi omume dechlorination nke CPE ka mma.
Polyethylene Chlorinated (HDPE) bụ ihe e ji polyethylene dị elu (HDPE) mee site na iji chlorine. Dịka usoro na ojiji dị iche iche si dị, enwere ike kewaa polyethylene chlorinated n'ime resin chlorinated polyethylene (CPE) na elastic chlorinated polyethylene (CM). Na mgbakwunye na resin thermoplastic nke enwere ike iji naanị ya, enwere ike ịgwakọta ha na polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS resin na ọbụna polyurethane (PU). N'ime ụlọ ọrụ roba, enwere ike iji CPE dị ka roba pụrụ iche dị elu, nke nwere arụmọrụ dị elu, enwere ike iji ya na roba ethylene-propylene (EPR), roba butyl (IIR), roba nitrile (NBR), polyethylene chlorosulfonated (CSM) Jiri ya na ihe ndị ọzọ dị na roba.
Àgwà nke Polyethylene Chlorined
1) CPE anaghị egbu egbu, ọ nweghị ọla dị arọ na polycyclic aromatic hydrocarbons, ọ na-emezukwa ihe achọrọ maka nchekwa gburugburu ebe obibi.
2) CPE nwere ezigbo iguzogide mmanụ, ọkachasị mmanụ ASTM1 na ASTM2, nke yiri NBR; ezigbo iguzogide mmanụ ASTM3, ka mma karịa CR ma yie CSM.
3) CPE nwere arụmọrụ dị elu nke na-ejupụta ihe, enwere ike ime ya ka ọ bụrụ ngwaahịa ndị na-emezu ihe dị iche iche achọrọ maka arụmọrụ. CPE nwere ike ịrụ ọrụ nke ọma ma dị na viscosity Mooney (ML1211+4) site na ọkwa 50 ruo 100.
4) CPE bụ roba jupụtara nke nwere ezigbo mgbochi oxidative ịka nká, mgbochi ozone ịka nká, iguzogide acid na alkali yana ihe ndị metụtara kemịkalụ.
5) CPE nwere ihe ndị dị na chlorine, nwere ezigbo ihe ndị na-egbochi ire ọkụ, ma nwee ihe ndị na-egbochi ire ọkụ. A na-eji ihe na-egbochi ire ọkụ nke dabeere na antimony, paraffin a chlorine na Al(OH)3 ọnụ n'ókè kwesịrị ekwesị iji nweta ihe na-egbochi ire ọkụ nke nwere ezigbo arụmọrụ na-egbochi ire ọkụ na ọnụ ala dị ala.
