Ndị na-emepụta CPE Polyethylene Chlorinated
Onye nchịkọta akụkọ nke onye na-emepụta ihe na-emepụta ihe na-eme ka ịka nká ga-ewebata gị taa okwu mmeghe dị mkpa gbasara onye na-emepụta chlorinated polyethylene cpe. Chlorinated polyethylene (CPE) bụ ngwaahịa a na-eji na-emepụta kemịkal. Ọtụtụ ndị mmadụ amaghị maka vinyl chloride chloride. Ghọta, mkpirisi Bekee nke polyethylene chlorinated bụ: CPE ma ọ bụ cm, chlorinated polyethylene (CPE) bụ ihe polymer jupụtara, ọdịdị ya bụ ntụ ntụ ọcha, adịghị egbu egbu na enweghị ụtọ, nke nwere oke ihu igwe, nguzogide ozone, nguzogide kemịkalụ na mgbochi ịka nká. , mma mmanu mmanu mmanu, ire retardancy na ìhè-shielding Njirimara. Ịdị ike dị mma (ka na-agbanwe agbanwe na -30 ° C), ezigbo ndakọrịta na ihe ndị ọzọ polymer, okpomọkụ dị elu, decomposition nke HCl, HCl nwere ike ime ka mmeghachi omume dechlorination nke CPE kwụsị.
Chlorinated polyethylene (HDPE) bụ ihe polymer mere site na nnukwu njupụta polyethylene (HDPE) site na chlorination. Dịka usoro na ojiji dị iche iche si dị, enwere ike kewaa polyethylene chlorinated ka ọ bụrụ polyethylene chlorinated resin (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), resin 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 iji ethylene-propylene roba (EPR), butyl rubber (IIR), nitrile rubber (NBR), chlorosulfonated polyethylene ( CSM) Jiri ya na ogige rọba ndị ọzọ.
Njirimara nke chlorinated Polyethylene
1) CPE adịghị egbu egbu, enweghị ọla dị arọ na polycyclic aromatic hydrocarbons, ma na-ezute ihe nchebe gburugburu ebe obibi.
2) CPE nwere mmanu mmanu mmanu, karịsịa ASTM1 na ASTM2 mmanụ, tụnyere NBR; ezigbo iguzogide mmanụ ASTM3, dị mma karịa CR ma tụnyere CSM.
3) CPE nwere arụmọrụ njuputa dị elu ma nwee ike mee ka ọ bụrụ ngwaahịa na-emezu ihe dị iche iche chọrọ. CPE nwere ezigbo igwe ma dị na Mooney viscosity (ML1211+4) akara ule sitere na 50 ruo 100.
4) CPE bụ rọba juputara na ịka nká nke ọma, ịka nká nke ozone, acid na alkali resistance na chemical Njirimara.
5) CPE nwere ihe chlorine, nwere ezigbo ihe na-egbochi ire ọkụ, ma nwee njirimara nke mgbochi ntapu ọkụ. A na-eji ihe mgbochi ọkụ nke dabeere na antimony, chlorinated paraffin na Al (OH) 3 ọnụ n'ụzọ kwesịrị ekwesị iji nweta ihe na-eme ka ọkụ na-eme ka ọkụ na-arụ ọrụ nke ọma na ọnụ ala dị ala.
