Mubuzima bwacu, CPE na PVC birakoreshwa cyane. Chlorine polyethylene ni polymer yuzuye ibintu byuzuye ifu yera, idafite uburozi kandi itaryoshye, kandi ifite ibihe byiza byo guhangana nikirere, kurwanya ozone, kurwanya imiti no kurwanya gusaza. Imikorere, hamwe namavuta meza yo kurwanya, flame retardancy hamwe nibiranga amabara. Gukomera kwiza (biracyahinduka kuri -30 ° C), guhuza neza nibindi bikoresho bya polymer, hamwe nubushyuhe bukabije. Chlorine polyethylene ni ibikoresho bya polymer bikozwe muri polyethylene yuzuye (HDPE) binyuze muburyo bwo gusimbuza chlorine. Ukurikije imiterere n'imikoreshereze itandukanye, polyethylene ya chlorine irashobora kugabanywamo ibyiciro bibiri: ubwoko bwa resin yo mu bwoko bwa chlorine polyethylene (CPE) hamwe na elastomer yo mu bwoko bwa chlorine polyethylene (CM). Usibye gukoreshwa wenyine, resinoplastique ishobora kandi kuvangwa na polyvinyl chloride (PVC), polyethylene (PE), polypropilene (PP), polystirene (PS), ABS ndetse na polyurethane (PU). Mu nganda za reberi, CPE irashobora gukoreshwa nkibikoresho byo mu rwego rwo hejuru, bifite ubuziranenge bwo mu rwego rwo hejuru, kandi birashobora no gukoreshwa na reberi ya Ethylene-propylene (EPR), butyl rubber (IIR), reberi ya nitrile (NBR), polyethylene ya chlorosulfone ( CSM), nibindi bindi bivanga bya reberi birakoreshwa.
Mu myaka ya za 1960, isosiyete yo mu Budage Hoechst yabanje guteza imbere no kumenya umusaruro w’inganda. igihugu cyanjye cyatangiye guteza imbere chlorine polyethylene mu mpera za za 70. "Aqueous Phase Suspension Synthesis of CPE Technology" yatunganijwe bwa mbere n’ikigo cy’ubushakashatsi bw’inganda za Anhui, kandi ibikoresho by’ibicuruzwa bya 500-1000t / a bifite umunzani bitandukanye byubatswe i Wuhu, Anhui, Taicang, Jiangsu, na Weifang, Shandong .
Kurwanya amavuta ya CPE ni impuzandengo, muri yo kurwanya amavuta ya ASTM No 1 na ASTM No 2 amavuta ni meza, ahwanye na NBR; kurwanya amavuta ya ASTM No 3 nibyiza, biruta CR, bihwanye na CSM.
CPE irimo chlorine, ifite ibintu byiza bya flame retardant kandi ifite ibiranga gutwika no kurwanya ibitonyanga. Irashobora guhuzwa hamwe na antimoni ishingiye kuri flame retardant, paraffine ya chlorine, na Al (OH) 3 mukigereranyo gikwiye kugirango ibone ibikoresho-bigabanya umuriro hamwe nibikorwa byiza bya flame-retardant kandi bihendutse.
CPE ntabwo ari uburozi, ntabwo irimo ibyuma biremereye na PAHS, kandi yujuje byuzuye ibisabwa byo kurengera ibidukikije.
CPE ifite imikorere yuzuye kandi irashobora gukorwa mubicuruzwa byujuje ibisabwa bitandukanye. CPE ifite imikorere myiza, Mooney viscosity (ML121 1 + 4) iri hagati ya 50-100, kandi hariho amanota menshi yo guhitamo.
