ʻO ka waiʻona polyvinyl (PVA) Wanwei
ʻO ka waiʻona polyvinyl (PVA) he polymer hiki ke hoʻohaumia ʻole i ka wai, maʻamau keʻokeʻo a i ʻole ka melemele liʻiliʻi, flake, granular a pauda paʻa.ʻO kāna hana ma waena o ka plastic a me ka rubber.Loaʻa iā ia ka adhesion maikaʻi, ka hiki ke hana kiʻiʻoniʻoni, ka insulation, ka pale ʻana i ka aila, ke kūpaʻa abrasion a me ka waiwai pale kinoea, etc.
Hoohana Huahana
ʻO ka polyvinyl alcohol (PVA) he ākea ka hoʻohana ʻana.
I ka ʻoihana textile, hoʻohana ʻia ia e like me ka warp slurry, ka mea hoʻopau lole lole, a me nā mea hoʻopili o nā lole i ulana ʻole ʻia.
I ka ʻoihana kūkulu, hoʻohana ʻia ia e like me nā mea hoʻohui sima, hoʻoheheʻe ʻia i ka pā pā, a me nā glues hale.
I ka ʻoihana kemika, hoʻohana ʻia ka semulsion stabilizer a me nā dispersants.
I ka ʻoihana hana pepa, hoʻohana ʻia ia e like me nā mea hoʻopili.
I ka hoʻohui, hiki ke hoʻohana ʻia i ka ʻoihana cosmetic, mahiʻai, ʻoihana lāʻau lapaʻau, etc.
