PVC hnab looj tesyog cov hnab looj tes nyias ua los ntawm kev sib xyaw polyvinyl chloride paste resin, plasticizer, stabilizer thiab viscosity-txo tus neeg saib xyuas rau hauv cov yas paste resin, uas yog impregnated, qhuav thiab plasticized los ntawm cov txheej txheem.
Cov yam ntxwv ntawm cov hnab looj tes PVC
PVC hnab looj tesyog ua los ntawm polyvinyl chloride los ntawm cov txheej txheem tshwj xeeb.Cov hnab looj tes tsis muaj allergen, tsis muaj hmoov, tsis muaj plua plav, tsis muaj ionic cov ntsiab lus, tsis muaj plasticizers, esters, silicone roj thiab lwm yam khoom, nrog rau cov tshuaj muaj zog tiv thaiv, zoo saj zawg zog thiab kov, yooj yim thiab xis hnav, nrog tiv thaiv. Cov khoom zoo li qub, thiab tuaj yeem siv rau hauv qhov chaw tsis muaj plua plav.
Nta: 1. Resistant rau qaug zog acids thiab alkalis;2. Cov ntsiab lus ionic tsawg;3. Zoo yoog raws thiab kov;4. Haum rau cov txheej txheem ntau lawm xws li semiconductors, kua muaju thiab hard disks.
PVC hnab looj tes siv ntau yam
1, Cov khoom siv PVC zoo.2 、 Siv dav rau ob txhais tes, dov ntug dab teg qhib.3 、 Cov txheej txheem tom qab kev kho mob tshwj xeeb, tsis muaj qhov khaus tawv nqaij, ua xua tshwm sim.4, Tsawg plua plav tiam thiab cov ntsiab lus ionic, lub tshuab nqus plua plav-dawb ntim.5, Muaj feem xyuam rau kev ntxuav chav tsev / chav huv / huv rhiav / semiconductor, hard disk manufacturing, precision optics, optical electronics, LCD / DVD kua siv lead ua, tshuaj lom neeg, precision instruments, PCB luam ntawv thiab lwm yam lag luam.PVC hnab looj tes yog dav siv rau kev tiv thaiv kev ua haujlwm thiab kev tu cev hauv tsev hauv kev tshuaj xyuas kev noj qab haus huv, kev lag luam khoom noj, tshuaj lom neeg kev lag luam, kev lag luam hluav taws xob, kev lag luam tshuaj, kev lag luam xim thiab txheej, luam ntawv thiab dyeing kev lag luam, kev ua liaj ua teb, hav zoov, tsiaj txhu thiab lwm yam lag luam.

Ntxiv txhua yam ntawm raw cov ntaub ntawv hauv kev faib ua feem, do ib zaug kom defoam thiab cia nws sawv ntsug, lim, do ob zaug thiab nqus defoam.
PVC hnab looj tes ntau lawm txheej txheem
Tom qab lim, nqus thiab sawv, qhov sib tov yog pumped rau hauv lub impregnation tank ntawm cov kab ntau lawm.Raws li kev tsim khoom ib txwm muaj, tes pwm ntawm txoj kab tuaj yeem nkag mus rau hauv lub tank impregnation, thiab cov pwm pwm nrog emulsion txuas tuaj tawm ntawm lub tank impregnation tig, tig tsis tu ncua thaum lub peb hlis ntuj kom cov emulsion ntawm tes pwm tsis zoo. , thiab ua kom cov emulsion ntau dhau los.Cov kua dej ntws rov qab mus rau lub tank impregnation los ntawm lub tank sau.Tom qab tso cov emulsion ntau dhau lawm, tes pwm txav nrog cov kab ntau lawm rau hauv qhov cub, qhov cub kub tswj ntawm 230-250 degrees Celsius thiab emulsion ntawm tes kov yog siav thiab tsim nyob rau hauv cov xwm txheej no.Cov tes pwm los ntawm qhov cub yog txias txias, di ncauj dov thiab hmoov, thiab ces cov hnab looj tes yog manually tshem tawm ntawm tes pwm, uas txav mus rau lub impregnation tank.Cov hnab looj tes PVC unloaded yog hmoov thiab tom qab ntawd khaws cia ua cov khoom tiav.
