Cov hauv qab no yog cov txheej txheem los txhim kho cov nplaim hluav taws xob ntawm PVC insulated saj zawg zog cables:
1. Ua kom zoo dua cov khoom siv PVC
Ntxiv nplaim retardants: Qhov no yog ib txoj hauv kev tseem ceeb los txhim kho cov nplaim hluav taws xob ntawm PVC insulated saj zawg zog cables. Cov nplaim hluav taws tsis zoo xws li txhuas hydroxide thiab magnesium hydroxide nqus cov cua sov ntau thaum lawv tawg los ntawm tshav kub, txo qhov kub thiab txias, thiab tso dej vapor mus rau dilute cov roj combustible. Qhov sib xyaw tsim nyog ntawm ntau cov nplaim hluav taws tuaj yeem ua rau muaj kev sib koom ua ke thiab ua kom zoo dua cov nplaim hluav taws kub ua haujlwm.
Siv PVC resin nrog cov ntsiab lus chlorine siab: Cov tshuaj chlorine nws tus kheej yog nplaim taws. Ua kom cov ntsiab lus chlorine hauv PVC resin tuaj yeem txhim kho cov nplaim hluav taws xob muaj peev xwm ntawm cov khoom siv. Txawm li cas los xij, qhov no yuav tsum tau ua yam tsis muaj kev cuam tshuam rau qhov yooj thiab lwm yam khoom ntawm lub cable.
2. Txhim kho cov txheej txheem ntau lawm
Kev ua kom zoo ntawm cov txheej txheem sib xyaw: Thaum lub sij hawm tsim khoom, nws yog ib qho tseem ceeb kom ntseeg tau tias cov nplaim hluav taws xob sib npaug sib xyaw nrog PVC cob thiab lwm yam khoom ntxiv. Siv cov khoom siv high-speed high-speed mixers thiab cov khoom siv hauv tsev thiab lwm yam khoom siv, tswj xyuas qhov tsis sib xws xws li lub sijhawm sib xyaw, qhov kub thiab txias, kom cov nplaim hluav taws kub hnyiab tau sib npaug hauv PVC matrix los xyuas kom meej tias txhua feem tuaj yeem ua lub luag haujlwm ntawm nplaim taws.
Extrusion txheej txheem hloov: tsim nyog kho qhov tsis xws li extrusion kub, siab thiab ceev. Qhov tsim nyog extrusion kub tuaj yeem ua tiav cov khoom yas tsis muaj decomposition, kom ntseeg tau qhov zoo thiab nplaim hluav taws kub ntawm PVC rwb thaiv tsev txheej. Nyob rau tib lub sijhawm, ruaj khov extrusion siab thiab ceev tuaj yeem zam qhov cuam tshuam ntawm rwb thaiv tsev los ntawm kev ntxhov siab hauv zos tsis sib xws thiab ua rau cov nplaim hluav taws kub hnyiab tau faib rau hauv cov txheej txheem rwb thaiv tsev.
3. Ntxiv nplaim retardant tiv thaiv txheej
Nyob rau hauv cov qauv tsim ntawm lub cable, nws muaj peev xwm txiav txim siab ntxiv ib txheej ntawm cov ntaub ntawv sheath nrog cov nplaim hluav taws kub retardancy sab nraum PVC rwb thaiv tsev txheej. Piv txwv li, cov khoom siv polyolefin nrog cov nplaim hluav taws zoo los yog cov khoom siv roj hmab nrog cov nplaim hluav taws tshwj xeeb ntxiv yog siv los ua cov txheej txheem sab nrauv, uas ua haujlwm ua ke nrog PVC rwb thaiv tsev txheej los txhim kho cov nplaim hluav taws xob tag nrho ntawm cov cable. Nyob rau hauv txoj kev no, txawm hais tias PVC rwb thaiv tsev txheej yog ignited nyob rau hauv huab cua txias, lub txheej sheath kuj yuav tiv thaiv kom txhob kis tau tus kab mob.
4. Txhim khu kev soj ntsuam thiab tswj kom zoo
Tsim kom muaj kev soj ntsuam nruj nruj kom kuaj cov nplaim hluav taws kub nyhiab ntawm cov khoom siv raw kom paub tseeb tias txhua pawg ntawm PVC resin, nplaim hluav taws kub, thiab lwm yam ua tau raws li qhov yuav tsum tau ua. Thaum lub sij hawm tsim cov txheej txheem, coj mus kuaj thiab kuaj ib nrab thiab tiav cov cables, thiab ntsuas cov nplaim hluav taws xob ntawm cov cables los ntawm kev ntsuas oxygen ntsuas, ntsuas hluav taws xob ntsug thiab lwm txoj hauv kev. Rau cov khoom uas tsis ua raws li cov qauv, kho cov txheej txheem lossis hloov cov ntaub ntawv raw hauv lub sijhawm kom ntseeg tau tias cov nplaim hluav taws xob ntawm lub Hoobkas cables ua tau raws li cov qauv.
