Qee qhov teeb meem hais txog chlorinated polyethylene:

Chlorinated polyethylene (CPE) yog cov khoom siv polymer saturated nrog cov hmoov dawb, tsis muaj tshuaj lom thiab tsis muaj ntxhiab. Nws muaj cov huab cua zoo heev, ozone tsis kam, tshuaj tiv thaiv, thiab kev laus ua haujlwm, nrog rau cov roj zoo, nplaim hluav taws kub, thiab xim xim. Zoo toughness (tseem saj zawg zog ntawm -30 ℃), zoo compatibility nrog rau lwm cov ntaub ntawv polymer, siab decomposition kub, decomposition ua HCL, uas muaj peev xwm catalyze lub dechlorination cov tshuaj tiv thaiv ntawm CPE.

Txoj kev aqueous ntawm chlorinated polyethylene feem ntau yog siv, uas muaj cov nqi tsim khoom tsawg thiab tsis muaj kuab paug. Lwm txoj kev yog txoj kev ncua kev kawm, uas yog tus paub tab. Cov khoom siv hauv tsev tuaj yeem dhau mus rau theem nrab txoj kev loj hlob thiab daim ntawv thov nrog kev loj hlob sai, thiab kev ziab kom qhuav sai. Nws yog feem ntau siv nyob rau hauv cia tank thiab steel qauv los txhim kho kev tsim kho kev ruaj ntseg.

Cov qauv hauv tsev chlorinated polyethylene (CPE) feem ntau raug txheeb xyuas los ntawm cov lej xws li 135A, 140B, thiab lwm yam. Thawj tus lej 1 thiab 2 sawv cev rau qhov seem crystallinity (TAC tus nqi), 1 sawv cev rau TAC tus nqi ntawm 0 thiab 10%, 2 sawv cev rau TAC tus nqi> 10%, tus lej thib ob thiab tus lej thib peb sawv cev rau cov ntsiab lus chlorine, piv txwv li, 35 sawv cev rau cov ntsiab lus chlorine ntawm 35%, thiab tus lej kawg yog tsab ntawv ABC, uas yog siv los qhia qhov hnyav molecular ntawm cov khoom siv raw PE. A yog qhov loj tshaj plaws thiab C yog qhov tsawg tshaj plaws.

Kev cuam tshuam ntawm qhov hnyav molecular: Chlorinated polyethylene (CPE) muaj qhov hnyav tshaj plaws molecular thiab siab melting viscosity hauv nws cov khoom A-hom. Nws viscosity phim PVC zoo tshaj plaws thiab nws muaj qhov zoo tshaj plaws dispersion nyhuv hauv PVC, tsim ib qho zoo tagnrho network xws li daim ntawv dispersion. Yog li ntawd, CPE cov khoom siv A-hom feem ntau yog xaiv los ua tus hloov kho rau PVC.

Feem ntau yog siv rau: hlau thiab cable (coal mine cables, xov hlau teev nyob rau hauv UL thiab VDE cov qauv), hydraulic hose, tsheb hose, daim kab xev, roj hmab phaj, PVC profile yeeb nkab hloov, cov khoom sib nqus, ABS hloov, thiab hais txog. Tshwj xeeb tshaj yog txoj kev loj hlob ntawm cov hlau thiab cable kev lag luam thiab lub tsheb qhov chaw tsim kev lag luam tau tsav qhov kev thov rau roj hmab raws li CPE noj. Roj hmab raws li CPE yog cov roj hmab hluavtaws tshwj xeeb uas muaj kev ua tau zoo tshaj plaws, tiv thaiv tshav kub rau oxygen thiab ozone laus, thiab nplaim hluav taws zoo heev.

Cov yam ntxwv cuam tshuam rau lub thermal decomposition kub ntawm CPE

Cov khoom ntawm CPE nws tus kheej muaj feem xyuam rau nws cov ntsiab lus chlorine. Yog tias cov ntsiab lus chlorine siab, nws yooj yim dua rau decompose;

Nws muaj feem xyuam rau purity. Kev tshem tawm tsis txaus ntawm cov pib, catalysts, acids, bases, thiab lwm yam ntxiv thaum lub sij hawm polymerization txheej txheem, los yog nqus dej thaum lub sij hawm cia thiab tsheb thauj mus los, yuav txo tau cov stability ntawm lub polymer. Cov tshuaj no tuaj yeem ua rau cov tshuaj tiv thaiv molecular ion degradation, thiab CPE muaj ntau cov khoom hnyav molecular xws li Cl2 thiab HCl, uas tuaj yeem ua kom lub thermal decomposition ntawm cov resin;
