Wasu matsaloli game da polyethylene chlorinated:

Chlorinated polyethylene (CPE) cikakken kayan polymer ne tare da bayyanar farin foda, mara guba da wari. Yana da kyakkyawan juriya na yanayi, juriya na ozone, juriya na sinadarai, da juriya na tsufa, da kuma juriya mai kyau, jinkirin harshen wuta, da kaddarorin canza launi. Kyakkyawan tauri (har yanzu m a -30 ℃), dacewa mai kyau tare da sauran kayan polymer, babban zafin jiki na bazuwa, bazuwar yana haifar da HCL, wanda zai iya haifar da halayen dechlorination na CPE.

Ana amfani da hanyar ruwa mai ruwa na chlorinated polyethylene, wanda ke da ƙarancin farashin samarwa da ƙazanta mara kyau. Wata hanyar ita ce hanyar dakatarwa, wacce ta balaga. Na gida na iya samun ci gaba na biyu da aikace-aikace tare da saurin ci gaba, kuma saurin bushewa yana da sauri. An fi amfani da shi a cikin tankunan ajiya da tsarin ƙarfe don inganta amincin ginin.

Samfurin chlorinated polyethylene (CPE) gabaɗaya ana gano su ta lambobi kamar 135A, 140B, da sauransu. Lambobin farko 1 da 2 suna wakiltar ragowar crystallinity (ƙimar TAC), 1 yana wakiltar ƙimar TAC tsakanin 0 da 10%, 2 yana wakiltar TAC darajar> 10%, lambobi na biyu da na uku suna wakiltar abun ciki na chlorine, alal misali, 35 yana wakiltar abun ciki na chlorine na 35%, kuma lambobi na ƙarshe shine harafin ABC, wanda ake amfani dashi don nuna nauyin kwayoyin halitta na PE. A shine mafi girma kuma C shine mafi ƙanƙanta.

Tasirin nauyin kwayoyin halitta: Chlorinated polyethylene (CPE) yana da mafi girman nauyin kwayoyin halitta da babban danko mai narkewa a cikin kayan sa na A-type. Dankonta yayi daidai da PVC mafi kyau kuma yana da mafi kyawun tasirin watsawa a cikin PVC, yana samar da ingantaccen hanyar sadarwa kamar nau'in watsawa. Saboda haka, nau'in nau'in CPE na A-nau'in ana zabar gabaɗaya azaman mai gyara ga PVC.

Yafi amfani da: waya da na USB (cibi mine igiyoyi, wayoyi da aka kayyade a UL da VDE matsayin), na'ura mai aiki da karfin ruwa tiyo, abin hawa tiyo, tef, roba farantin, PVC profile bututu gyara, Magnetic kayan, ABS gyara, da sauransu. Musamman ci gaban masana'antar waya da na USB da masana'antar kera motoci ya haifar da buƙatar amfani da CPE na roba. Rubber tushen CPE shine roba na roba na musamman tare da ingantaccen aiki mai mahimmanci, juriya ga iskar oxygen da tsufa na ozone, da kyakkyawan jinkirin harshen wuta.

Abubuwan da ke shafar yanayin zafin thermal bazuwar CPE

Kaddarorin CPE kanta suna da alaƙa da abun ciki na chlorine. Idan abun ciki na chlorine yana da yawa, yana da sauƙi don bazuwa;

Yana da alaƙa da tsarki. Rashin isasshen cirewa na masu farawa, masu haɓakawa, acid, tushe, da dai sauransu da aka ƙara yayin aikin polymerization, ko shayar da ruwa a lokacin ajiya da sufuri, na iya rage kwanciyar hankali na polymer. Wadannan abubuwa zasu iya haifar da halayen lalata kwayoyin halitta, kuma CPE ya ƙunshi ƙarin ƙananan nauyin kwayoyin halitta kamar Cl2 da HCl, wanda zai iya hanzarta bazuwar thermal na resin;
