Lus Qhia Txog
Polyvinyl alcohol (PVA) yog koj tawm ntawv hais tawm thiab muaj tebchaw rau hwm nyob rau hauv lub tsis noj ntau ntawm. Yog muaj tebchaw qhov sawv, film npawb, oil resistance, surface activity, gas barrier, wear resistance, thiab cov kev pab ib tug. PVA yog muaj txog kev caij lus yam ntawd polyols thiab muaj txog kev tshem los ntawm, kawg li yog muaj tebchaw qab nyob thiab muaj ib tug qhia ntawm cov synthetic materials. Cov txoj kev muaj yog li thiab cov kev pab ntau ntawm li cas PVA yog muaj ib tug polymer organic chemical raw material tej sib.
Cov Industrial Chain
Rau hauv lub upstream ntawm PVA yog muaj ib tug basic chemical raw material tej sib, muaj rau hauv coal, acetic acid, vinyl acetate, thiab cov kev. Lub downstream yog muaj tebchaw thiab muaj tawm ntawm thiab muaj tawm ntawm PVA fibers, adhesives, textile pulp, PVB, thiab cov kev. Terminal requirements muaj tebchaw thiab muaj tawm ntawm synthetic fibers, building adhesives, white latex, glass intermediate films, biodegradable PVA films, thiab cov kev.
