CPE (Chlorinated Polyethylene), ua ib qho kev hloov pauv, feem ntau yog siv rau hauv cov xov hlau thiab cov cables los txhim kho kev ua tau zoo ntawm cov ntaub ntawv thiab ua tiav cov ntawv thov tseem ceeb. Nws cov haujlwm tseem ceeb tau pom nyob rau hauv cov hauv qab no:
1. Kev txhim kho kev ua tau zoo tseem ceeb
1. Kev tiv thaiv kub thiab kev ntseeg siab zoo dua
Qhov kub ua haujlwm ntev ntawm CPE hloov kho cov cables tuaj yeem ncav cuag 90 ℃ (cov mis zoo tuaj yeem ncav cuag 105 ℃), siab dua qhov txwv siab tshaj plaws ntawm 60-65 ℃ ntawm cov khoom siv roj hmab ib txwm muaj, thaum txhim kho kev laus cua sov thiab kev ua haujlwm tiv thaiv ozone. Nws cov qauv molecular saturated muab kev tiv thaiv huab cua zoo heev thiab hloov kho rau cov chaw sab nraum zoov nyuaj.
2. Tiv thaiv hluav taws thiab txhim kho kev nyab xeeb
Cov tshuaj chlorine uas muaj cov atoms ua rau CPE muaj peev xwm tiv taus hluav taws, ua tau raws li cov qauv kev nyab xeeb xws li UL-94, tshwj xeeb tshaj yog rau cov xwm txheej muaj kev pheej hmoo siab xws li cov xov hlau mining. Nws tsim cov pa luam yeeb tsawg thaum lub sijhawm hlawv thiab tsis tso cov pa roj lom heev.
3. Kev ua haujlwm zoo dua qub
Ntxiv CPE tuaj yeem ua kom lub zog cuam tshuam ntawm cov ntaub thaiv cable (lub zog cuam tshuam nce 3-4 zaug tom qab ntxiv 8-10 feem ntawm CPE rau PVC cov ntaub ntawv hauv paus), thiab txhim kho kev tiv thaiv roj, kev tiv thaiv flexural, thiab kev tiv thaiv hnav, ua rau lub neej ua haujlwm ntev dua.
Cov txheej txheem thiab cov nqi zoo dua
1. Kev ua kom yooj yim hloov kho
Qhov kub ntawm CPE sib tov yog dav (50-160 ℃), nrog rau cov menyuam tsis lo thiab cov yam ntxwv tsis kub hnyiab, ua rau kev ua haujlwm ntau ntxiv zoo dua. Cov roj hmab sib xyaw tseem siv tau ruaj khov tom qab khaws cia rau hauv chav sov li 1-2 xyoos.
2. Kev siv nyiaj tsim nyog
Cov khoom ntim zoo (muaj peev xwm haum rau cov hmoov av ntau xws li calcium carbonate) txo cov gel kom qis dua 25% thaum tswj cov khoom siv lub cev thiab ua kom cov nqi tsim khoom zoo dua.
Cov xwm txheej thov tshwj xeeb
Kev tiv thaiv txheej rwb thaiv tsev: CPE tsis ua rau lub hauv paus tooj liab paug thaum siv ua txheej rwb thaiv tsev qis-voltage, ua kom muaj kev ruaj khov ntawm kev ua hluav taws xob.
Xim thiab Kev Tiv Thaiv Ib puag ncig: Xim dawb txhawb nqa xim ci, hloov cov roj hmab ntuj / roj hmab chloroprene daj; Tsis txhob ua kom cov kuab tshuaj lom heev thaum lub sijhawm tsim khoom.
Cov xov hlau tshwj xeeb: Cov xwm txheej xav tau ntau xws li cov xov hlau hauv qhov av thee, cov xov hlau nqa, thiab cov xov hlau tshuab vuam vam khom lawv cov khoom sib xyaw ua ke ntawm kev tiv taus roj, kev tiv taus cua sov, thiab kev tiv taus hluav taws.
