Thoob Ntiaj Teb - Premier PVC Paste Resin: Cov Polymer Tshwj Xeeb rau Kev Siv Ntau Yam
Cov Khoom Siv Lub Cev thiab Tshuaj
Qhov tsos thiab kev sib xws: Hauv nws lub xeev ib txwm muaj, PVC Paste Resin zoo li du, homogeneous paste nrog cov qauv creamy. Qhov loj me ntawm PVC hauv cov paste yog qhov zoo heev, feem ntau yog nyob rau hauv ntau ntawm 0.1 - 2 microns, uas pab txhawb rau nws cov dej ntws zoo heev thiab muaj peev xwm yooj yim thov lossis pwm rau hauv ntau yam duab.
Qhov nplaum: Qhov viscosity ntawm PVC Paste Resin tuaj yeem hloov kho tau meej los ntawm kev hloov pauv hom thiab qhov ntau ntawm cov yas siv, nrog rau lwm yam khoom ntxiv. Cov nplaum viscosity qis dua yog qhov zoo tagnrho rau cov ntawv thov uas xav tau kev ua haujlwm siab, xws li dip molding, thaum cov nplaum viscosity siab dua yog qhov tsim nyog rau cov txheej txheem xws li slush molding lossis casting.
Kev coj cwj pwm yas: Thaum cua sov, cov tshuaj plasticizer hauv PVC Paste Resin nkag mus rau hauv cov khoom PVC, ua rau lawv o thiab sib xyaw ua ke, ua rau cov khoom khov kho, yoog tau, lossis nruj nyob ntawm cov qauv. Cov txheej txheem plasticization no tuaj yeem thim rov qab rau qee qhov, tso cai rau kev rov ua dua yog tias tsim nyog.
Kev Ruaj Ntseg Tshuaj: Zoo ib yam li lwm cov khoom PVC, PVC Paste Resin ua rau pom kev tiv taus ntau yam tshuaj, suav nrog cov kua qaub, alkalis, thiab ntau cov kuab tshuaj. Txawm li cas los xij, nws cov tshuaj tiv taus tuaj yeem txhim kho lossis hloov kho ntxiv los ntawm kev ntxiv cov tshuaj stabilizers thiab cov khoom ntxiv.
Cov Cheeb Tsam Thov
Kev Siv Txheej thiab Txheej: Siv dav rau kev txheej ntau yam khoom siv xws li hlau, ntoo, thiab ntaub. Hauv kev lag luam tsheb, nws siv rau lub tsheb chassis thiab cov khoom hauv qab lub cev kom tiv thaiv kev xeb thiab rwb thaiv suab. Rau cov rooj tog thiab cov khoom siv hluav taws xob, PVC Paste Resin - cov txheej txheem ua los ntawm PVC muab qhov ruaj khov, zoo nkauj uas tiv taus khawb thiab xim av.
Kev Tsim Khoom Ua Si: Ib yam khoom siv uas nyiam siv hauv kev tsim cov khoom ua si vim nws muaj kev nyab xeeb, yoog tau yooj yim, thiab yooj yim rau kev pwm. Nws siv tau los tsim cov khoom ua si mos mos, cov duab ua yeeb yam, thiab lwm yam khoom ua si nrog cov duab ntxaws ntxaws thiab cov xim ci ntsa iab. Qhov me me ntawm cov resin ua kom muaj qhov chaw du, ua rau cov khoom ua si muaj kev nyab xeeb rau cov menyuam yaus tuav.
Kev Lag Luam Khau: Siv rau hauv kev tsim cov khau hauv qab, cov khoom siv sab saud, thiab lwm yam khoom. Cov ntaub ntawv khau ua los ntawm PVC Paste Resin paub txog lawv qhov yooj ywm, ruaj khov, thiab tiv taus kev hnav thiab rhuav. Lawv tuaj yeem hloov kho tau yooj yim kom tau raws li cov qauv tsim sib txawv, muab ntau yam xim thiab cov qauv.
Cov Khoom Siv Kho Mob: Siv rau hauv kev tsim cov khoom siv kho mob, xws li cov hnab looj tes pov tseg, cov tes ntsuas ntshav siab, thiab qee hom raj. Nws qhov biocompatibility tuaj yeem txhim kho los ntawm kev tsim thiab ua kom raug, kom ntseeg tau tias nws ua tau raws li cov qauv kev nyab xeeb thiab kev huv huv uas xav tau hauv kev kho mob.
Cov Txheej Txheem Npaj
Kev sib xyaw ua ke ntawm emulsion: Qhov no yog ib qho ntawm cov txheej txheem siv rau kev tsim cov PVC Paste Resin. Vinyl chloride monomers raug faib rau hauv dej nrog rau emulsifiers thiab initiators. Cov polymer particles uas tshwm sim yog me me thiab sib xws, uas yog qhov zoo rau kev ua tiav cov nplaum du. Tom qab polymerization, cov emulsion feem ntau yog ua tiav kom tshem tawm cov emulsifier thiab lwm yam impurities, thiab tom qab ntawd sib xyaw nrog plasticizers thiab lwm yam additives los tsim cov nplaum kawg.
Kev sib xyaw ua ke ntawm pawg: Hauv cov txheej txheem polymerization loj, vinyl chloride monomers raug polymerized tsis muaj cov kuab tshuaj, ua rau cov khoom PVC muaj qhov huv siab. Cov polymer tom qab ntawd raug zom ua cov khoom me me thiab sib xyaw nrog cov plasticizers thiab lwm yam khoom los tsim cov tshuaj nplaum. Txoj kev no tuaj yeem tsim cov PVC Paste Resin nrog cov khoom zoo heev, tab sis nws xav tau cov khoom siv ua haujlwm nyuaj dua thiab kev tswj hwm cov txheej txheem nruj.
Kev Hloov Kho Polymerization Suspension: Qee cov chaw tsim khoom siv cov txheej txheem polymerization suspension hloov kho los tsim cov PVC Paste Resin. Los ntawm kev kho cov xwm txheej polymerization thiab hom cov neeg sawv cev suspension, lawv tuaj yeem tswj qhov loj me thiab cov duab ntawm cov khoom PVC kom tau txais cov khoom nplaum xav tau. Txoj kev no muab kev sib npaug ntawm cov khoom zoo thiab tus nqi tsim khoom.
Cov kev ceev faj
Cov Cai Khaws Cia: Cov tshuaj pleev PVC yuav tsum khaws cia rau qhov chaw txias thiab qhuav kom deb ntawm tshav ntuj ncaj qha thiab qhov chaw kub. Kev raug rau qhov kub siab tuaj yeem ua rau cov tshuaj yas ua kom qhuav lossis cov tshuaj yas ua kom sai sai, cuam tshuam rau nws qhov zoo thiab kev ua tau zoo. Nws tseem ceeb heev kom khaws cov thawv cia kom nruj kom tiv thaiv cov dej noo thiab cua nkag, uas tuaj yeem ua rau cov tshuaj yas puas tsuaj.
Kev Nyab Xeeb Hauv Kev Tuav: Thaum lub sijhawm ua haujlwm, yuav tsum ceev faj kom tsis txhob raug rau daim tawv nqaij thiab qhov muag. Cov tshuaj plasticizers thiab lwm yam khoom ntxiv hauv cov tshuaj nplaum yuav ua rau khaus lossis ua xua rau qee tus neeg. Cov neeg ua haujlwm yuav tsum hnav cov khoom siv tiv thaiv tus kheej, xws li hnab looj tes thiab tsom iav kev nyab xeeb. Yog tias muaj kev sib cuag tsis raug, qhov chaw raug mob yuav tsum tau ntxuav tam sim ntawd nrog dej ntau, thiab yuav tsum nrhiav kev kho mob yog tias tsim nyog.
Cov Kev Xav Txog Kev Ua Haujlwm: Thaum ua cov PVC Paste Resin, kev tswj qhov kub thiab txias kom zoo yog qhov tseem ceeb heev. Kev kub dhau tuaj yeem ua rau PVC lwj thiab tso cov pa phem tawm, xws li hydrogen chloride. Yuav tsum muaj cua nkag kom txaus hauv thaj chaw ua cov khoom kom ntseeg tau tias cov neeg ua haujlwm muaj kev nyab xeeb thiab tiv thaiv kev sib sau ua ke ntawm cov pa lom. Tsis tas li ntawd, kev siv cov tshuaj stabilizers thiab cov khoom pab ua cov khoom siv tuaj yeem pab txhim kho kev ruaj khov thermal thiab kev ua haujlwm ntawm cov khoom siv paste.
