I-Chlorinated Polyethylene CPE Abavelisi
Umhleli womvelisi we-agent anti-aging uya kukwazisa namhlanje isingeniso esifanelekileyo malunga nomvelisi we-polyethylene cpe ene-chlorine. I-Chlorinated polyethylene (CPE) yimveliso esetyenziselwa ukuveliswa kweekhemikhali. Abantu abaninzi abazi malunga ne-vinyl chloride chloride. Qonda, isishunqulelo IsiNgesi polyethylene chlorine yile: CPE okanye cm, chlorinated polyethylene (CPE) i polyethylene saturated, inkangeleko ngumgubo omhlophe, non-yityhefu kunye incasa, kunye nokumelana nemozulu ebalaseleyo, ukumelana ozone, ukumelana imichiza kunye Ukuguga ukumelana. , ukuchasana kakuhle kweoli, ukunqandwa komlilo kunye neempawu zokukhusela ukukhanya. Ukuqina okulungileyo (kusaguquguquka kwi -30 ° C), ukuhambelana kakuhle nezinye izinto zepolymer, ubushushu obuphezulu bokubola, ukubola kweHCl, i-HCl inokubangela ukusabela kwe-dechlorination ye-CPE.
I-Chlorinated polyethylene (i-HDPE) i-polymer material eyenziwe kwi-polyethylene ephezulu (HDPE) nge-chlorination. Ngokwezakhiwo ezahlukeneyo kunye nokusetyenziswa, i-polyethylene ene-chlorine inokwahlulwa ibe yi-resin chlorinated polyethylene (CPE) kunye ne-elastic chlorinated polyethylene (CM). Ukongeza kwii-resin ze-thermoplastic ezinokuthi zisetyenziswe zodwa, ziyakwazi ukuxutywa kunye ne-polyvinyl chloride (PVC), i-polyethylene (PE), i-polypropylene (PP), i-polystyrene (PS), i-resin ye-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) Sebenzisa kunye nezinye iikhompawundi zerabha.
Iipropati ze-Chlorinated Polyethylene
I-1) i-CPE ayinayo ityhefu, ayinazo isinyithi esinzima kunye ne-polycyclic aromatics hydrocarbons, kwaye ihlangabezana ngokupheleleyo neemfuno zokusingqongileyo.
2) I-CPE inokumelana neoli egqwesileyo, ngakumbi i-ASTM1 kunye ne-ASTM2 ioli, efaniswa ne-NBR; ukumelana okugqwesileyo kwi-ASTM3 yeoli, engcono kune-CR kwaye inokuthelekiswa ne-CSM.
I-3) I-CPE inokusebenza okuphezulu kokuzaliswa kwaye inokwenziwa kwiimveliso ezihlangabezana neemfuno ezahlukeneyo zokusebenza. I-CPE inobuchule obugqwesileyo kwaye ifumaneka kwi-Mooney viscosity (ML1211+4) amabakala ukusuka kwi-50 ukuya kwi-100.
I-4) I-CPE i-rubber egcweleyo kunye nokuguga okugqwesileyo kwe-anti-oxidative, ukuguga kwe-anti-ozone, ukuxhathisa kwe-asidi kunye ne-alkali kunye neepropati zeekhemikhali.
I-5) I-CPE iqulethe izinto zeklorini, ineempawu ezintle zokunqanda ilangatye, kwaye ineempawu zokutshisa i-anti-drip. I-antimony-based retardant flame retardant, iparafini ekloriniwe kunye ne-Al(OH)3 zisetyenziswa kunye ngokomlinganiselo ofanelekileyo ukuze kufumaneke imathiriyeli yokunqanda amadangatye kunye nokusebenza kakuhle kwedangatye kunye nexabiso eliphantsi.
