Kubomi bethu, iCPE kunye nePVC zisetyenziswa kakhulu kwaye zisetyenziswa ngokubanzi. I-Chlorinated polyethylene yimathiriyeli egcweleyo yepolymer enembonakalo yomgubo omhlophe, ayinayo ityhefu kwaye ayinancasa, kwaye inokumelana nemozulu ebalaseleyo, ukumelana ne-ozone, ukuxhathisa imichiza kunye nokungagugi. Ukusebenza, kunye nokuchasana kweoli okulungileyo, ukungabikho komlilo kunye neempawu zombala. Ukuqina okulungileyo (kusaguquguquka kwi -30 ° C), ukuhambelana kakuhle nezinye izinto zepolymer, kunye nobushushu obuphezulu bokubola. I-Chlorinated polyethylene yimathiriyeli ye-polymer eyenziwe kwi-high-density polyethylene (HDPE) ngokusebenzisa i-chlorination substitution reaction. Ngokwezakhiwo ezahlukeneyo kunye nokusetyenziswa, i-polyethylene ene-chlorine inokwahlulwa ibe ngamacandelo amabini: i-resin-type chlorinated polyethylene (CPE) kunye ne-elastomer-type chlorinated polyethylene (CM). Ukongeza ekusebenziseni yodwa, i-thermoplastic resins inokudityaniswa ne-polyvinyl chloride (PVC), i-polyethylene (PE), i-polypropylene (PP), i-polystyrene (PS), i-ABS kunye ne-polyurethane (PU). Kwishishini le-rubber, i-CPE ingasetyenziselwa njengomgangatho ophezulu, umgangatho ophezulu werabha ekhethekileyo, kwaye ingasetyenziselwa irabha ye-ethylene-propylene (EPR), irabha ye-butyl (IIR), i-nitrile rubber (NBR), i-chlorosulfonated polyethylene ( CSM), njl. Ezinye iingxube zerabha ziyasetyenziswa.
Ngeminyaka yoo-1960, inkampani yaseJamani iHoechst yaqala yaphuhlisa ngempumelelo kwaye yaqonda imveliso yoshishino. ilizwe lam laqala ukuphuhlisa ipolyethylene eneklorini ekupheleni kweminyaka yoo-1970. "I-Aqueous Phase Suspension Synthesis ye-CPE Technology" yaphuhliswa ngempumelelo yi-Anhui Chemical Industry Research Institute, kunye nezixhobo zokuvelisa i-500-1000t / a kunye nezikali ezahlukeneyo zakhiwe eWuhu, Anhui, Taicang, Jiangsu, kunye ne-Weifang, eShandong. .
Ukuxhatshazwa kweoli ye-CPE yi-avareji, phakathi kwayo ukuchasana ne-ASTM No. 1 yeoli kunye ne-ASTM No. ukuchasana ne-ASTM No. 3 yeoli igqwesileyo, ingcono kune-CR, elingana ne-CSM.
I-CPE iqulethe i-chlorine, eneempawu ezintle zokunqanda ilangatye kwaye ineempawu zokutshisa kunye nokuchasana nokuvuza. Inokudityaniswa ne-antimony-based flame retardant, iparafini eneklorini, kunye ne-Al(OH) 3 ngokomlinganiselo ofanelekileyo wokufumana izinto ezinqanda amadangatye kunye nokusebenza okugqwesileyo komlilo kunye neendleko eziphantsi.
I-CPE ayinayo ityhefu, ayiqulathanga isinyithi esinzima kunye ne-PAHS, kwaye ihlangabezana ngokupheleleyo neemfuno zokusingqongileyo.
I-CPE inokusebenza kokuzaliswa okuphezulu kwaye inokwenziwa kwiimveliso ezihlangabezana neemfuno ezahlukeneyo zokusebenza. I-CPE inokuqhubekeka kakuhle, i-Mooney viscosity (ML121 1+4) iphakathi kwe-50-100, kwaye kukho amabakala amaninzi onokukhetha kuwo.
