Muaj nuj nqi thiab siv polyvinyl cawv
Kev haus dej cawv yog ib qho tseem ceeb ntawm cov khoom siv mis nyuj muaj siv hauv cov khoom siv roj polyvinyl, cov roj av, cov hnab nplaum, thiab lwm yam}
1, Vinylon Raw Khoom
Cov roj hmab roj hmab muaj peev xwm tsim los ntawm polyvinyl cawv tom qab ua kom tawg, thiab tom qab ntawd los ntawm kev kho cov ris tsho, ntaub, ntses cuab tam {}}}
2. warp sizing
. pva raws li slurry muaj cov nplaum zoo nkauj thiab kev ua yeeb yaj kiab zoo nkauj, txhawb nqa kev ua yeeb yaj kiab, txhawb nqa kev ua yeeb yam zoo nkauj thiab ua yeeb yaj kiab zoo nkauj ntaub tshuab {{. Zoo nkauj} Thiab cov ntaub zoo nkaus li nkaws thiab muag heev, tsis txhob ntxhib {}
b, polyvinyl cawv yog dej-soluble polymer tebchaw, sib xyaw, sizing, desizing yooj yim.
3.} kua nplaum
{. Cov kua roj ntsha polyvinyl muaj rau cov ntaub ntawv kev nyab xeeb thiab cov ntaub ntawv, thiab lwm yam kua nplaum}}} kraft ntawv hnab siv rau ntim cov khoom hnyav xws li MAAs, nplej, thiab lwm yam}}} ua cov nplaum {6.
b, Polyurea Resin thiab Phenolico resin hloov los ntawm polyvinyl cawv tuaj yeem siv ua cov nplaum rau laminates {}}
c, polyvinyl cawv aqueous tov (los ntawm kev ntxiv cov fillers uas tsim nyog, ntxiv siv rau hauv kev npaj cov adhesives .
D, hauv qab catalyylas condensates nrog formaldehyde, xws li siv lub zog, cov nplaum, cov iav kev nyab xeeb, cov iav kev nyab xeeb, kev nyab xeeb iav interlayers thiab lwm yam Teb .
e, polyvinyl cawv yog ib qho zoo heev tiv thaiv thiab tsis sib xws ntawm vinulsion (cov kua nplaum uas yog qhov tseem ceeb hauv kev tsim khoom dawb .
4, Kev Ua Ntawv
Ib qho kev haus dej cawv, cov yeeb yaj kiab uas tuaj yeem txhim kho cov ntawv sau ua yeeb yam, cov duab kos duab, roj tsis kam thiab tshuaj lom neeg ua haujlwm ntawm cov ntawv.
B, cov xim xim: tuaj yeem txhim kho cov ntawv dawb thiab cov ntawv ci ntsa iab yog qhov zoo, qoj xim, txhim kho ntawv.
c, sab hauv sizing sizen tus neeg sawv cev: thaum ua cov ntawv, pulp, kom cov ntawv uas tau muaj zog .
5, Polyvinyl Cawv Zaj Duab Xis
Zaj duab xis ua los ntawm cov khoom lag luam zoo, muaj cov tshuaj tiv thaiv zoo, cov roj av muaj txiaj ntsig zoo, yog li nws tau siv cov tshuaj}} Ib qho me me yog siv rau Optics thiab lwm yam {{2 2}}
Yog pva cob muaj tshuaj lom
Kws Tshuaj Zos Polyvinylinyl Cawv, tsis muaj kev phom sij rau tib neeg lub cev, tsis muaj kev phom sij rau tib neeg lub cev, nws yog cov khaub ncaws zoo, nws yog cov tshuaj lom neeg muaj zog, nws yog cov yeeb yaj kiab zoo nkauj, nws yog cov dej cawv zoo nkauj, nws yog cov tshuaj lom tej yam tseem siv tau siv .
Nws txoj kev nyab xeeb tuaj yeem pom hauv cov khoom siv rau cov qauv siv lub ntsej muag, thiab muaj cov yeeb yaj kiab uas muaj kev nyab xeeb, thiab yog cov yeeb yaj kiab kev nyab xeeb hauv cov tshuaj pleev ib ce.
