I-Chlorinated polyethylene (CPE) yimathiriyeli yepolymer egcweleyo, ukubonakala komgubo omhlophe, ongeyotyhefu kwaye ongenancasa, kunye nokumelana nemozulu ebalaseleyo, ukuxhathisa kwe-ozone, ukuxhathisa imichiza kunye nokuguga, kunye nokuxhathisa okulungileyo kweoli, i-flame retardant kunye neempawu zombala.Ukuqina okuhle (kusenokuguquka ku -30 ℃), kuhambelana kakuhle nezinye izixhobo zepolymer, ubushushu obuphezulu bokubola, ukubola kweHCl, iHCl inokwenza i-dechlorination reaction yeCPE.
Igama elisemthethweni: I-Chlorinated Polyethylene, Ufinyezo: I-CPE, I-Chlorinated i-polyethylene yimathiriyeli ye-polymer elungiswe ukusuka kwi-polyethylene ephezulu yoxinaniso (i-HDPE) nge-chlorination substitution reaction.Ngokwesakhiwo esahlukileyo kunye nokusetyenziswa, i-polyethylene ene-chlorine inokwahlulwa ibe yi-resin chlorinated polyethylene (CPE) kunye nohlobo lwe-elastic chlorinated polyethylene (CM) iindidi ezimbini.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 njenge-rubber ephezulu, umgangatho ophezulu werabha ekhethekileyo, kwaye ingaxutywa kunye ne-ethylene propylene rubber (EPR), irabha ye-butyl (IIR), irabha ye-nitrile butadiene (NBR), i-chlorosulfonated polyethylene ( CSM) kunye nezinye iirubha.
Iimpawu zeCPE
I-1, i-CPE luhlobo lwerabha ehluthisiweyo, inokumelana nobushushu obugqwesileyo be-oksijini ukuguga, ukuguga kwe-ozone, ukuxhathisa kwe-asidi kunye ne-alkali, iipropati zeekhemikhali.
I-2, ukuchasana kweoli ye-CPE ngokuqhelekileyo, kunye nokuchasana kwe-ASTM 1 ioli kunye ne-ASTM 2 ioli ihle kakhulu, ilingana ne-NBR;Ukuchasana okugqwesileyo kwi-ASTM 3 yeoli, ingcono kune-CR, kwaye inokuthelekiswa ne-CSM.
I-3, i-CPE iqulethe i-chlorine, inomsebenzi ogqwesileyo we-flame retardant, kwaye ineempawu zokutsha zokuchasana nokuvuza.Isixhobo sokubuyiswa komlilo kunye nokusebenza kakuhle kwe-flame retardant kunye neendleko eziphantsi zinokufunyanwa ngomlinganiselo ofanelekileyo we-antimony flame retardant, iparafini ekloriniwe kunye ne-Al(OH)3.
4. I-CPE ayinayo ityhefu, ayinayo isinyithi esinzima kunye nee-PAH, kwaye ihlangabezana ngokupheleleyo neemfuno zokusingqongileyo.
I-5, i-CPE inokusebenza okuphezulu kokuzaliswa, inokulungiswa ukuhlangabezana neemfuno ezahlukeneyo zokusebenza kwemveliso.I-CPE inomsebenzi omhle wokucubungula kunye ne-Mooney viscosity ifumaneka kwiindidi ezahlukeneyo zamabakala phakathi kwe-50-100.
