Qee qhov teeb meem hais txog chlorinated polyethylene:

Chlorinated polyethylene (CPE) yog cov khoom siv polymer uas muaj cov hmoov dawb zoo li hmoov, tsis muaj tshuaj lom thiab tsis muaj ntxhiab. Nws muaj kev tiv thaiv huab cua zoo heev, tiv thaiv ozone, tiv thaiv tshuaj lom neeg, thiab tiv thaiv kev laus, nrog rau kev tiv thaiv roj, hluav taws kub, thiab xim zoo. Zoo toughness (tseem yoog tau ntawm -30 ℃), sib raug zoo nrog lwm cov ntaub ntawv polymer, qhov kub siab decomposition, decomposition tsim HCL, uas tuaj yeem ua rau CPE dechlorination reaction.

Feem ntau siv cov txheej txheem dej ntawm chlorinated polyethylene, uas muaj cov nqi tsim khoom tsawg thiab tsis muaj kuab paug. Lwm txoj hauv kev yog txoj kev ncua, uas yog qhov paub tab. Cov hauv tsev tuaj yeem dhau los ua kev txhim kho thib ob thiab daim ntawv thov nrog kev txhim kho sai, thiab qhov ceev ziab yog ceev. Nws feem ntau siv rau hauv cov thoob dej cia khoom thiab cov qauv hlau los txhim kho kev nyab xeeb ntawm kev tsim kho.

Cov qauv chlorinated polyethylene (CPE) hauv tsev feem ntau yog txheeb xyuas los ntawm cov lej xws li 135A, 140B, thiab lwm yam. Cov lej thawj zaug 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 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 me tshaj plaws.

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

Feem ntau siv rau: hlau thiab cable (cov hlau hauv av thee, cov hlau teev tseg hauv UL thiab VDE tus qauv), hydraulic hose, tsheb hose, daim kab xev, roj hmab phaj, PVC profile yeeb nkab hloov kho, cov ntaub ntawv sib nqus, ABS hloov kho, thiab lwm yam. Tshwj xeeb tshaj yog kev txhim kho ntawm kev lag luam hlau thiab cable thiab kev lag luam tsim khoom siv tsheb tau tsav qhov kev thov rau roj hmab raws li CPE noj. Roj hmab raws li CPE yog cov roj hmab tshwj xeeb nrog kev ua tau zoo heev, tiv taus cua sov rau oxygen thiab ozone laus, thiab zoo heev nplaim taws retardant.

Cov yam tseem ceeb uas cuam tshuam rau qhov kub ntawm CPE thaum lub sijhawm tawg ua kub

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

Nws muaj feem cuam tshuam nrog kev huv. Kev tshem tawm tsis txaus ntawm cov initiators, catalysts, acids, bases, thiab lwm yam ntxiv thaum lub sijhawm polymerization, lossis kev nqus dej thaum lub sijhawm khaws cia thiab kev thauj mus los, tuaj yeem txo qhov kev ruaj khov ntawm cov polymer. Cov tshuaj no tuaj yeem ua rau muaj kev puas tsuaj ntawm cov tshuaj molecular ion, thiab CPE muaj cov tshuaj molecular qis dua xws li Cl2 thiab HCl, uas tuaj yeem ua kom cov thermal decomposition ntawm cov resin sai dua;
