4. Zida Zomangira:

a.Zogulitsa za Gypsum:

PVA imawonjezedwa kuzinthu zopangidwa ndi gypsum monga zophatikizira, ma pulasitala, ndi zomatira pakhoma.Imawongolera magwiridwe antchito, kumamatira, komanso kukana kwa ma gypsum formulations.

b.Zogulitsa Simenti:

Zowonjezera za PVA zimagwiritsidwa ntchito pazida za simenti monga matope, ma renders, ndi zomatira matailosi kuti apititse patsogolo kugwira ntchito, kumamatira, komanso kulimba.Amathandizira kusungirako madzi, kukana kwamadzi, komanso mphamvu zama bond pakumanga.

5. Zosamalira Munthu:

a.Zodzoladzola:

Zochokera ku PVA zimagwiritsidwa ntchito mu zodzoladzola ndi zinthu zosamalira anthu monga ma gels okometsera tsitsi, mafuta opaka, ndi mafuta odzola.Amakhala ngati thickeners, opanga mafilimu, ndi okhazikika, kupereka mawonekedwe, mamasukidwe akayendedwe, ndi kukhazikika kwa mapangidwe.

b.Contact Lens Solutions:

PVA imagwiritsidwa ntchito munjira zolumikizirana ndi mandala ngati mafuta opaka mafuta komanso kunyowetsa.Zimathandiza kusunga chinyezi ndi chitonthozo pamwamba pa ma lens, kuchepetsa mikangano ndi kukwiya panthawi yovala.

6. Ntchito Zamankhwala:

a.Zopaka Pamapiritsi:

Zovala zopangidwa ndi PVA zimagwiritsidwa ntchito popanga mapiritsi amankhwala kuti apereke zinthu za enteric, zokhazikika, kapena zochedwa kutulutsa.Amateteza zinthu zomwe zimagwira ntchito kuti zisawonongeke, zimayang'anira kutulutsidwa kwa mankhwala, ndikuwongolera kutsatira kwa odwala.

b.Zothandizira:

Zochokera ku PVA zimagwiritsidwa ntchito ngati zowonjezera m'mapangidwe amankhwala pomanga, kupasuka, ndi kukhuthala.Amawonjezera mphamvu ya piritsi, kukhazikika, ndi bioavailability mumitundu yolimba ya mlingo.

Pomaliza:

Polyvinyl Alcohol (PVA) ndi polima wosunthika womwe umagwiritsidwa ntchito mosiyanasiyana pakupanga zomatira ndi zomatira, komanso m'mafakitale ena osiyanasiyana monga nsalu, mapepala, kulongedza, zomangamanga, chisamaliro chamunthu, ndi mankhwala.Makhalidwe ake apadera, kuphatikiza kusungunuka kwamadzi, kumamatira, kupanga mafilimu, ndi biocompatibility, zimapangitsa kuti zikhale zofunikira pakugwiritsa ntchito mosiyanasiyana m'magawo osiyanasiyana.Zotsatira zake, PVA ikupitilizabe kukhala chinthu chogwiritsidwa ntchito kwambiri komanso chofunikira kwambiri pamafakitale ambiri ndi ogula.
