Cov txiaj ntsig ntawm kev siv cov polyethylene chlorinated hauv cov cables online

1. Txhim kho qib kev txawj ntse ntawm cov khoom siv cable
Cov thev naus laus zis CPE muaj kev ua tau zoo tag nrho, tiv taus hluav taws kub thiab roj, tiv taus kev laus ntawm cua sov, tiv taus ozone, tiv taus huab cua, thiab ua haujlwm zoo hauv kev sib tov. Nws yuav luag tsis kub hnyiab thiab khaws cia ntev yam tsis muaj kev puas tsuaj, ua rau nws yog cov khoom siv cable zoo.
Qhov kub ua haujlwm ntev ntawm CPE yog 90 ℃, thiab ntev li ntev tau cov mis tsim nyog, nws qhov kub ua haujlwm siab tshaj plaws tuaj yeem ncav cuag 105 ℃. Daim ntawv thov ntawm CPE tuaj yeem ua rau qib tsim cov roj hmab cables los ntawm 65 ℃ mus rau qib ntawm 75-90 ℃ lossis txawm tias 105 ℃ hauv cov tebchaws tsim kho txawv teb chaws. CPE nplaum nws tus kheej yog dawb li daus, yog li txawm tias nws siv ua rwb thaiv tsev lossis sheath, nws tuaj yeem ua rau cov khoom muaj yeeb yuj raws li tus neeg siv xav tau. Txawm li cas los xij, cov khoom ib txwm muaj xws li roj hmab ntuj, styrene butadiene roj hmab, chloroprene roj hmab, thiab nitrile roj hmab nyuaj rau tsim cov xim dawb huv lossis zoo nkauj vim lawv daj. Tsis tas li ntawd, cov roj hmab chloroprene feem ntau siv thiab chlorosulfonated polyethylene roj hmab muaj teeb meem nyuaj rau daws teeb meem xws li monomer thiab cov kuab tshuaj lom, volatilization, thiab lwm yam thaum lub sijhawm tsim khoom. Hauv kev khaws cia, kev thauj mus los, thiab kev tsim cov cable, teeb meem xws li scorching thiab roller sticking feem ntau tshwm sim. Rau CPE, cov teeb meem mob taub hau no yuav luag tsis muaj. Lwm qhov tseem ceeb uas yuav tsum nco ntsoov yog tias thaum siv chlorine rau kev rwb thaiv tsev qis-voltage, nws yuav tsis ua rau lub hauv paus tooj liab qias neeg, uas tsis muaj qhov tsis ntseeg tias yuav txhim kho qib ntawm cov thev naus laus zis cable.
2. Kev hloov pauv tau yooj yim, tus nqi qis, thiab kev ua tau nyiaj ntau
Tom qab raug extruded los ntawm roj hmab extruder, CPE sib xyaw roj hmab tuaj yeem raug thermally crosslinked ntawm qhov kub siab lossis crosslinked los ntawm electron irradiation ntawm chav tsev kub. Txawm li cas los xij, cov roj hmab chloroprene ib txwm tsis tuaj yeem raug crosslinked los ntawm electron irradiation, thiab cov roj hmab styrene butadiene ib txwm tsis haum rau irradiation crosslinking.
3. Kev kho cov qauv ntawm cov khoom siv cable yog qhov zoo
Raws li cov xov hlau thiab cov cables uas muaj zog tsawg, lawv feem ntau muab faib ua ob pawg raws li lawv siv: cov xov hlau siv hauv kev tsim kho thiab cov xov hlau rau cov khoom siv hluav taws xob. Vim nws muaj ntau yam zoo uas cov roj hmab hluavtaws tsis muaj, CPE tuaj yeem siv dav hauv kev tsim cov xov hlau hluav taws xob hauv tsev thiab lwm cov xov hlau rau cov khoom siv hluav taws xob.
