1. Polyethylene ifite chlorine, izwi kandi nka CPE mu Cyongereza, ni ubwoko bwa polyethylene. Polyethylene ifite chlorine (CPE) ni ibikoresho biboneka binyuze mu gusimbuza atome za hydrogène kuri polyethylene ifite ubucucike bwinshi (HDPE) hamwe na atome za chlorine. CPE igaragara nk'ifu yera, idahumanya kandi nta mpumuro igira.
2. Polyethylene ifite chlorine ikozwe muri polyethylene ifite umuvuduko muto HDPE ifite ubushobozi bwo kurwanya ubushyuhe bwinshi n'ubushyuhe bwinshi kurusha polyethylene ifite chlorine ikozwe muri polyethylene ifite umuvuduko mwinshi. Muri rusange, polyethylene ifite ubucucike bwa 0.93-0.96g/cm3, uburemere busanzwe bwa molekile 50000 kugeza 250000, n'ikimenyetso cyo gushonga kiri hagati ya 0.01 na 2.0g/10min ni byo bikunze gukoreshwa mu gukora polyethylene ifite chlorine. Igipimo cya chlorine ya polyethylene ifite chlorine bigira ingaruka zikomeye ku miterere yayo. Iyo chlorine iri munsi ya 15%, iba ipulasitiki; Iyo chlorine iri hagati ya 16-24%, iba irastomer ya thermoplastic; elastomer nk'iy'umukara ifite chlorine iri hagati ya 25-48%; Iyo chlorine iri hagati ya 49-58%, iba irastomer ikomeye isa n'uruhu; Iyo chlorine igeze kuri 73%, iba irashya. Klorini igera kuri 27% muri polyethylene ifite umuvuduko mwinshi bikuraho burundu kristali, mu gihe klorini igera kuri 30% muri polyethylene ifite umuvuduko muto ifite kristali nyinshi bikuraho burundu crystalize. Nk'icyuma gikoresha icyuma gishyushya, chlorize iri hagati ya 30-40%. Kuri ubu, chlorize iri hagati ya 25-45% na chlorize. Iyo chlorize yiyongera, chlorize iri hagati ya peteroli, umwuka uhumeka, n'umuriro ugabanuka birarushaho kuba byiza; Iyo chlorize igabanutse, imikorere yayo irushaho gukomera, ubwihangane, n'ubushobozi bwo gukanda burushaho kuba bwiza.
2. Ibiranga CPE ya Chlorine Polyethylene
1) CPE ni umupira wuzuye ufite ubushobozi bwo kurwanya ubushyuhe n'umwuka wa ogisijeni, urwanya gusaza kwa ozone, urwanya aside na alkali, hamwe n'imiterere y'imiti.
2) CPE ifite ubushobozi bwo guhangana n'amavuta neza, ifite ubushobozi bwo guhangana n'amavuta ya ASTM 1 na ASTM 2, ingana na NBR; ifite ubushobozi bwo guhangana n'amavuta ya ASTM No. 3, irusha CR kandi ingana na CSM.
3) CPE irimo chlorine, ifite ubushobozi bwiza bwo kudatwika umuriro kandi ifite ubushobozi bwo kurwanya gushyuha no kugabanya amazi. Ishobora guhuzwa n'ibidatwika umuriro bishingiye kuri antimoni, parafini ifite chlorine, na Al (OH) 3 mu rugero rukwiye kugira ngo haboneke ibikoresho bidatwika umuriro bifite ubushobozi bwiza bwo kudatwika umuriro kandi bihendutse.
4) CPE ntabwo ari uburozi, nta byuma biremereye na PAH, kandi yujuje ibisabwa ku bidukikije.
5) CPE ifite ubushobozi bwo kuzuza neza kandi ishobora gukora ibicuruzwa byujuje ibisabwa bitandukanye. CPE ifite ubushobozi bwo gutunganya neza, kandi hari amanota menshi yo guhitamo afite ubukana bwa Mooney buri hagati ya 50-100.
