Polyvinyl cawv CAS: 25213-24-5

Cawv polyvinyl (PVA) siv dav hauv ntau yam lag luam vim nws cov yam ntxwv zoo kawg. Hauv kev lag luam nplaum, nws ua haujlwm ua cov khoom tseem ceeb hauv ntau yam qauv, muab cov khoom sib txuas zoo hauv cov ntawv thov xws li cov kua nplaum ntoo mus rau cov ntawv nplaum. Nws cov dej-soluble thiab cov peev xwm tsim zaj duab xis ua rau nws tsis tseem ceeb hauv kev tsim cov khoom ntim dej-soluble, hnab ntxhua khaub ncaws, thiab cov neeg sawv cev ntsuas textile, muab cov kev daws teeb meem rau cov kev xav tau ntim khoom zoo rau ib puag ncig thiab yaj tau. Hauv kev lag luam textile, PVA siv dav ua tus neeg sawv cev ntsuas warp los txhim kho cov txheej txheem weaving, muab lub zog thiab kev ywj pheej rau cov xov paj. Tsis tas li ntawd, nws ua haujlwm ua tus tiv thaiv colloid hauv kev tsim cov vinyl acetate-based copolymers thiab ua tus binder hauv kev luam ntawv xim. Tsis tas li ntawd, PVA ua lub luag haujlwm tseem ceeb hauv kev lag luam ntawv, qhov twg nws siv ua tus neeg sawv cev ntsuas qhov chaw los txhim kho daim ntawv lub zog, luam ntawv, thiab nqus kua mem. Cov lag luam tshuaj thiab zaub mov siv PVA hauv kev tsim cov tshuaj ntsiav, ua tus neeg sawv cev txheej rau cov ntsiav tshuaj, thiab hauv kev tsim cov yeeb yaj kiab noj tau rau cov ntim khoom noj. Nws qhov biocompatibility thiab tsis muaj tshuaj lom kuj ua rau PVA yog ib qho khoom siv muaj txiaj ntsig zoo hauv kev siv kho mob, suav nrog ua ib feem ntawm cov ntaub qhwv qhov txhab, cov txheej txheem xa tshuaj, thiab cov ntaub so ntswg engineering scaffolds. Zuag qhia tag nrho, ntau yam kev siv ntawm PVA qhia txog nws qhov tseem ceeb ua ib qho polymer ntau yam hauv ntau yam kev lag luam thiab kev lag luam.
