Roj Hmab CPE yog cov roj hmab hluavtaws tshwj xeeb uas muaj kev ua tau zoo, kev kub-tiv taus oxygen-ozone laus, thiab cov nplaim hluav taws zoo. Feem ntau siv nyob rau hauv: hlau thiab cables (cables rau thee mines, xov hlau teev nyob rau hauv UL thiab VDE qauv), hydraulic hoses, automotive hoses, tapes, roj hmab los xij, PVC profile yeeb nkab hloov kho, cov khoom sib nqus, ABS hloov, thiab lwm yam.
Ntawm lawv, daim ntawv thov feem ntau muaj cov haujlwm hauv qab no:
1. Txhim kho lub tshuab filling
CPE yog ib hom roj hmab uas tsis yog-tus kheej txhawb zog, thiab nws xav tau kev txhawb zog kom ua tiav lub zog zoo dua. Nws lub zog filling system zoo ib yam li cov roj hmab dav dav. Tus neeg sawv cev txhawb nqa feem ntau yog carbon dub thiab dawb carbon dub. Dawb carbon dub tuaj yeem txhim kho nws cov kua muag tiv thaiv, thiab tuaj yeem tsim cov txheej txheem meta-methyl dawb los txhim kho nws cov nplaum rau lub pob txha. . CPE muaj cov khoom ua haujlwm siab, thiab lub tshuab filling feem ntau suav nrog calcium carbonate, talcum hmoov, av nplaum thiab lwm yam.
2. Plasticizing system
Ester plasticizers yog cov plasticizers feem ntau siv rau CPE, xws li dioctyl phthalate (DOP) thiab dioctyl adipate (DOA). Lawv solubility tsis nyob ze rau cov CM thiab lawv compatibility yog zoo. DOA thiab DOS yog siv nyob rau hauv cov roj hmab tebchaw los muab lawv zoo heev txias kuj.
3. Kev tiv thaiv ruaj khov
Thaum CPE yog cua sov los yog vulcanized (tsis yog-peroxide vulcanization system), hydrogen chloride yuav raug tso tawm. Yog li ntawd, stabilizers nrog acid absorption yuav tsum tau siv nyob rau hauv lub formulation, xws li calcium stearate, barium stearate, tribasic lead sulfate los yog Magnesium oxide.
