Daim ntawv thov PVA
1. Textile Warp sizing tus neeg saib xyuas
Kev tiv thaiv txheej rau ntuj fiber ntau thiab hluavtaws fiber ntau ua ntej weaving hauv kev lag luam textile. Nws pab ua kom lub zog tensile ntawm cov xov paj, txo tus nqi tawg.
2.Textile / Npuag xov chemicals
Textile tiav chemicals siv nyob rau hauv kev ua, muab textile ntau zog, anti-wrinkle, anti-shrinking, los yog lwm yam khoom tshwj xeeb.
3. Kua nplaum
PVA kua nplaum, raws li cov khoom tseem ceeb hauv dej-raws li cov nplaum, xws li cov kua nplaum dawb thiab cov kua nplaum ntoo. Nws ua raws li kev tiv thaiv colloid, muab cov yeeb yaj kiab zoo heev - tsim cov khoom, muaj zog adhesion rau cov porous nto xws li ntawv, ntoo, thiab ntaub, thiab zoo tiv taus roj thiab cov kuab tshuaj.
4. Ntawv kev lag luam
PVA tau siv los ua tus neeg saib xyuas qhov chaw los txhim kho daim ntawv lub zog, txhim kho cov roj thiab crease kuj. Kuj muab ib tug du nto uas absorbs number case tusyees. Ntxiv mus, PVA yog siv los ua cov ntawv khi rau hauv cov xim pleev xim, nrog rau kev khi pigments, txhim kho gloss thiab ci, thiab ua kom nruj.
5. Plywood woodworking kev lag luam
Polyvinyl Cawv tuaj yeem yog tus de- tus cwj pwm tus neeg sawv cev ntawm cov thermosetting resin feem ntau yog siv los ua tus neeg sawv cev khi xws li carbamide, formaldehyde resin thiab melamine, rau plywood, board khoom thiab ntoo ua.
6. PVAc, PVC, PS
Stabilizer rau emulsion, tiv thaiv colloids.PVA yog siv los tiv thaiv colloid rau polymerisation ntawm PVAC. Tiv thaiv cov khoom polymer los ntawm coalescing (ua ke ua ke) thaum lub sij hawm polymerization. Thiab siv nyob rau hauv ncua kev kawm ntawv polymerization (xws li, rau PVC) disperse monomer droplets nyob rau hauv dej.
7. Kev tsim kho kev lag luam
Cement additives, thiab molding adhesives. Nws txhim kho cov cement adhesion, fluidity thiab qeeb lub cement nto kom qhuav lub sij hawm, txhim kho lawv kev ua haujlwm, tiv thaiv kev tawg.
8. Raw khoom rau PVA daim txhuam cev thiab sib tsoo discs sanding ntawv
Raw khoom rau PVA daim txhuam cev thiab sib tsoo discs sanding ntawv. PVA ua haujlwm raws li cov qauv matrix thiab cov khoom siv absorbent. Nws muab sponge cov duab thiab resilience, thaum nws hydrophilic xwm enables sai sai nqus dej thiab tuav.
9. Cov khoom ntim khoom
Dej soluble films, ntxhua khaub ncaws pods zaj duab xis. PVA muaj dej txias solubility thiab siab barrier zog. Nws yog dav siv nyob rau hauv cov khaub ncaws ntxhua khaub ncaws / lub tshuab ntxhua khaub ncaws ntxhua khaub ncaws, ntxhua khaub ncaws ntxhua khaub ncaws, tshuaj ua liaj ua teb ntim paj ntaub rov qab zaj duab xis, chav tsev - koob ntim.
10. Kev lag luam luam ntawv
Kev tshuaj ntsuam luam ntawv photosensitive films (Photographic phaj photosensitive zaj duab xis), thiab zinc phaj priniting photosensitive films.
