Kev siv tshuab ua cov chlorinated polyethylene

Cov txheej txheem ua cov chlorinated polyethylene (CPE) feem ntau suav nrog cov txheej txheem ethylene chlorination thiab cov txheej txheem ethylene plasticization. Cov hauv qab no yog cov kauj ruam tshwj xeeb ntawm ob txoj hauv kev no:
Cov txheej txheem chlorination ethylene
1. Kev npaj cov catalyst: Npaj cov tshuaj txhuas chloride siv cov txheej txheem daws teeb meem lossis cov txheej txheem nag lossis daus.
2. Kev siv ethylene chlorine: Cov roj ethylene, cov roj chlorine, thiab cov catalyst raug xa mus rau hauv lub pej thuam chlorination. Los ntawm qhov muaj cov catalyst, cov roj ethylene raug tshuaj chlorination los tsim cov ethylene chloride.
3. Kev Ntxuav: Ntxuav cov vinyl chloride uas tsim tawm kom tshem tawm cov khoom tsis huv.
4. Kev Sib Sau Ua Ke: Cov vinyl chloride uas tau ntxuav lawm raug ntxiv rau hauv lub tshuab polymerization reactor, nrog rau cov initiators, regulators, thiab lwm yam additives, kom dhau los ntawm cov tshuaj polymerization reaction thiab tsim cov chlorinated polyethylene resin.
5. Kev ziab thiab zom: Qhuav thiab zom cov tshuaj polyethylene uas tau polymerized chlorinated kom tau cov tshuaj polyethylene hmoov.
Cov txheej txheem ethylene plasticization
Cov txheej txheem ethylene plasticization yog raws li cov txheej txheem ethylene chlorination, uas txhim kho qhov yooj ywm thiab kev ua haujlwm ntawm chlorinated polyethylene los ntawm kev ntxiv cov plasticizers.
Cov txheej txheem tsim cov polyethylene chlorinated kuj suav nrog txoj kev yaj, txoj kev khov kho, thiab txoj kev ncua. Ntawm lawv, txoj kev ncua yog muab faib ua txoj kev theem dej thiab txoj kev ncua hydrochloric acid theem. Txoj kev ncua hydrochloric acid chlorination tam sim no yog txoj kev tsim khoom siab tshaj plaws hauv ntiaj teb, uas muaj cov yam ntxwv ntawm cov txheej txheem tsim nyog thiab tsim nyog rau kev tsim khoom loj.
Cov teb thov ntawm chlorinated polyethylene
Chlorinated polyethylene, ua ib yam thermoplastic uas muaj ntau yam kev siv, muaj ntau yam kev siv. Nws tuaj yeem siv los ua cov kav dej, cov xov hlau thiab cov cables, cov plag tsev, cov khoom siv dai kom zoo nkauj, thiab lwm yam. Tsis tas li ntawd, chlorinated polyethylene kuj siv dav hauv cov teb xws li roj av, kev lag luam sib zog, kev lag luam tshuaj lom neeg, electroplating, luam ntawv thiab zas xim, cov khoom siv hauv tsev, kev tsav dav hlau, zaub mov, kev ua ntawv, kev ywg dej rau kev ua liaj ua teb, metallurgy, kev tsim nkoj, cov khoom siv hluav taws xob, textiles, thiab lwm yam.
Hauv kev xaus, cov txheej txheem ua cov polyethylene chlorinated feem ntau suav nrog cov txheej txheem ethylene chlorination thiab cov txheej txheem ethylene plasticization, nrog rau ntau txoj kev sib xyaw xws li txoj kev yaj, txoj kev khov kho, thiab txoj kev ncua. Cov txheej txheem no tau ua rau chlorinated polyethylene ua cov khoom siv ua tau zoo thiab siv dav.
