Abavelisi be-CPE ye-Chlorinated Polyethylene
Umhleli womenzi wearhente yokulwa nokwaluphala uza kwazisa namhlanje intshayelelo efanelekileyo malunga nomenzi we-cpe ene-chlorine e-polyethylene. I-chlorinated polyethylene (CPE) yimveliso esetyenziswa kwimveliso yeekhemikhali. Abantu abaninzi abazi nge-vinyl chloride chloride. Qonda, isifinyezo sesiNgesi se-chlorine polyethylene yi: CPE okanye cm, i-chlorined polyethylene (CPE) yinto ye-polymer egcweleyo, imbonakalo yayo yi-white powder, ayinatyhefu kwaye ayinancasa, inokumelana okuhle kwemozulu, ukumelana ne-ozone, ukumelana neekhemikhali kunye nokumelana nokwaluphala, ukumelana neoyile elungileyo, ukubambezeleka komlilo kunye neempawu zokukhusela ukukhanya. Ukuqina okuhle (kusaguquguquka kwi--30°C), ukuhambelana okuhle nezinye izinto ze-polymer, ubushushu obuphezulu bokubola, ukubola kwe-HCl, i-HCl inokunyusa ukusabela kwe-dechlorination ye-CPE.
I-polyethylene ekhlorini (HDPE) yinto eyenziwe nge-polymer eyenziwe nge-polyethylene ephezulu (HDPE) ngokuyikhlorini. Ngokwezakhiwo ezahlukeneyo kunye nokusetyenziswa, i-polyethylene ekhlorini inokwahlulwa ibe yi-resin chlorinated polyethylene (CPE) kunye ne-elastic chlorinated polyethylene (CM). Ukongeza kwii-thermoplastic resins ezinokusetyenziswa zodwa, zinokuxutywa ne-polyvinyl chloride (PVC), i-polyethylene (PE), i-polypropylene (PP), i-polystyrene (PS), i-ABS resin kunye ne-polyurethane (PU). Kwishishini lerabha, i-CPE ingasetyenziswa njengerabha ekhethekileyo esebenza kakuhle, ekumgangatho ophezulu, kwaye ingasetyenziswa nerabha ye-ethylene-propylene (EPR), irabha ye-butyl (IIR), irabha ye-nitrile (NBR), i-polyethylene ye-chlorosulfonated (CSM). Sebenzisa nezinye iikhompawundi zerabha.
Iimpawu zeChlorinated Polyethylene
1) I-CPE ayinabungozi, ayinazo iintsimbi ezinzima kunye nee-polycyclic aromatic hydrocarbons, kwaye ihlangabezana ngokupheleleyo neemfuno zokhuseleko lokusingqongileyo.
2) I-CPE inokumelana kakuhle neoyile, ngakumbi ii-oyile ze-ASTM1 kunye ne-ASTM2, ezifana ne-NBR; ukumelana okuhle neoyile ze-ASTM3, kungcono kune-CR kwaye kufana ne-CSM.
3) I-CPE inomgangatho ophezulu wokuzalisa kwaye ingenziwa iimveliso ezihlangabezana neemfuno ezahlukeneyo zokusebenza. I-CPE inomatshini osebenza kakuhle kwaye ifumaneka kwiindidi ze-Mooney viscosity (ML1211+4) ukusuka kuma-50 ukuya kwi-100.
4) I-CPE yirabha egcweleyo ene-anti-oxidative aging ebalaseleyo, i-anti-ozone aging, i-asidi kunye ne-alkali resistance kunye neempawu zeekhemikhali.
5) I-CPE iqulethe izinto ze-chlorine, ineempawu ezibalaseleyo zokungatshisi ilangatye, kwaye ineempawu zokutsha okuchasene nokuvuza. I-antimony-based flame retardant, i-chlorinated paraffin kunye ne-Al(OH)3 zisetyenziswa kunye ngokulinganayo ukuze kufunyanwe izinto ezithintela ilangatye ezisebenza kakuhle kwaye zibiza kancinci.
