Chaw Tsim Khoom Zoo Nqe PVB (Polyvinyl Butyral Resin) CAS: 63148-65-2

piav qhia luv luv:

Polyvinyl Butyral Resin (PVB) yog ib yam khoom uas raug polyvinyl cawv thiab butadhyde cog rau hauv qab acid catalytic. Vim tias PVB molecules muaj cov ceg ntev, lawv muaj qhov mos zoo, qhov kub ntawm iav qis, lub zog ncab siab thiab lub zog tiv thaiv kev cuam tshuam. PVB muaj kev pom tseeb zoo heev, solubility zoo, thiab tiv taus lub teeb zoo, tiv taus dej, tiv taus kub, tiv taus txias, thiab tsim zaj duab xis. Nws muaj cov pab pawg ua haujlwm uas tuaj yeem ua ntau yam kev tshuaj tiv thaiv xws li acetylene-based saponification reactions, vinegarization ntawm hydroxyl, thiab sulfonic acidization. Nws muaj kev sib txuas siab nrog iav, hlau (tshwj xeeb tshaj yog txhuas) thiab lwm yam khoom siv. Yog li ntawd, nws tau siv dav hauv kev tsim cov iav kev nyab xeeb, cov nplaum, cov ntawv paj ceramic, cov ntawv txhuas ntawv ci, cov ntaub ntawv hluav taws xob, cov khoom siv iav txhawb nqa, cov neeg sawv cev kho ntaub, thiab lwm yam, thiab dhau los ua cov khoom siv hluavtaws tseem ceeb.

Cov ntawv thov ntawm PVB

1. Cov zaj duab xis nyias siv los ua cov khoom siv sandwich rau cov iav muaj kev nyab xeeb. Cov iav muaj kev nyab xeeb zoo thiab muaj lub zog cuam tshuam siab. Nws yog siv dav hauv kev lag luam dav hlau thiab tsheb.
2. Nws yog siv los tsim cov hlau hauv qab thiab xim txias nrog kev nplaum zoo thiab dej tsis kam nrog kev nplaum zoo thiab dej tsis kam.
3. Nws yog siv los tsim cov ntawv paj yeeb yaj kiab ci ntsa iab, uas tuaj yeem hloov cov ntawv paj ceramic. Kev lag luam resin yog siv los tsim cov yas crusher rau cov hlau tsis yog ferrous xws li hlau thiab txhuas, uas tuaj yeem phim rau hauv ntau yam nplaum. Nws yog dav siv rau kev sib txuas ntawm ntoo, ceramic, hlau, yas, tawv, txheej ntawm cov ntaub ntawv siab.
4. Siv los ua cov tshuaj kho ntaub thiab lub raj mis gauze. Kev lag luam zaub mov siv los ua cov khoom ntim khoom lom.
5. Kev lag luam ua ntawv siv los ua cov tshuaj kho ntawv. Tsis tas li ntawd, nws tuaj yeem siv los tsim cov khoom tiv thaiv kev ntsws, cov tshuaj tawv thiab lwm yam khoom siv tsis pub dej nkag.
6. Nws siv tau rau qhov mos ntawm kev lag luam luam ntawv, kev luam ntawv concave, kev luam ntawv convex, kev luam ntawv silk net, kev hloov pauv cua sov, vim tias nws yaj hauv cawv thiab tsis muaj tshuaj lom, lub foob tsis nyob hauv qhov tsw, uas siv tau rau hauv kev lag luam zaub mov uas rhiab rau qhov tsw hauv kev lag luam zaub mov. Xws li tshuaj yej / luam yeeb. Vim tias cov resin yog cedic hom, nws muaj kev nplaum zoo heev rau ntawm qhov chaw ntawm lub iav nrog lub zog yin ion, uas yog qhov tshwj xeeb tshaj yog rau kev kho kom zoo nkauj iav phaj luam ntawv silk.
