PVA
Lag luam wholesale PVA Polyvinyl cawv
Cov khoom muag
Polyvinyl cawv (PVA) yog cov dej-soluble polymer uas feem ntau yog dawb hauv flake, flocculent, los yog hmoov.
Qhov thib ob, cov yam ntxwv ntawm cov khoom
Cov dej solubility zoo heev: nws tuaj yeem yaj hauv dej ntawm qhov sib txawv ntawm qhov kub thiab txias los tsim cov tshuaj pob tshab.
Zoo adhesion: muaj kev sib raug zoo ntawm ntau yam ntaub ntawv.
Kev tsim cov yeeb yaj kiab zoo heev: Cov yeeb yaj kiab tsim muaj lub zog siab thiab yoog raws.
Solvent resistance: Rau qee qhov, nws tuaj yeem tiv taus qhov yaig ntawm cov kuab tshuaj ntau.
Biocompatibility: Tus txheeb ze tsis muaj tshuaj lom thiab tus phooj ywg rau tib neeg lub cev thiab ib puag ncig.
khoom siv
Kev lag luam textile
Siv los ua warp sizing khoom los txhim kho lub zog thiab hnav tsis kam ntawm yarns.

Kev kho mob teb
Cov khoom siv raw ntawm cov tshuaj capsule, cov khoom pabcuam ntawm cov tshuaj ophthalmic.
Cov txheej txheem ntau lawm
Nws yog feem ntau npaj los ntawm alcoholysis ntawm polyvinyl acetate.
Kev lag luam zeem muag
Nrog rau qhov kev thov ntau ntxiv rau cov ntaub ntawv ua tau zoo hauv ntau qhov kev lag luam, kev lag luam kev cia siab rau PVA yog dav. Tsav los ntawm kev kho dua tshiab ntawm kev lag luam ib txwm muaj xws li textiles thiab papermaking, nrog rau kev txhim kho ntawm cov chaw tshiab xws li biomedicine thiab cov khoom siv hluav taws xob, nws cov kev xav tau ntawm kev lag luam yuav tsum tau nce ntxiv.
siv ceev faj
Tsis txhob ya raws thiab kub siab thaum khaws cia.
Thaum dissolving, qhov kub thiab nplawm ceev yuav tsum tau tswj xyuas kom txaus dissolution thiab kev ua tau zoo tsis cuam tshuam.
Xaiv cov qauv tsim nyog thiab cov lus qhia tshwj xeeb raws li kev thov sib txawv.
Piv txwv li, hauv kev lag luam textile, PVA nrog cov viscosity thiab alcoholysis degree yuav tsum tau xaiv raws li cov khoom thiab cov txheej txheem ntawm cov xov paj; Nyob rau hauv daim ntawv thov ntawm adhesives, kev tsim thiab kev siv ntawm PVA yuav tsum tau kho raws li qhov zoo ntawm cov nplaum.
Txhawm rau ua kom tiav, Polyvinyl cawv ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw nrog nws cov khoom tshwj xeeb, muab kev txhawb nqa zoo rau kev txhim kho cov kev lag luam muaj feem xyuam.
