ʻAʻona Polyvinyl

ʻO ka wehewehe pōkole:

ʻO ka waiʻona Polyvinyl kahi mea hoʻohuihui, ʻo ke ʻano kemika ʻo [C2H4O]n, ʻo ke ʻano he flake keʻokeʻo, flocculent a i ʻole pauka paʻa, ʻaʻohe ʻala. Hiki ke hoʻoheheʻe ʻia i ka wai (ma luna o 95 ℃), hiki ke hoʻoheheʻe ʻia i ka dimethyl sulfoxide, insoluble i ka ʻaila, kerosene, ka aila mea kanu, benzene, toluene, dichloroethane, carbon tetrachloride, acetone, ethyl acetate, methanol, ethylene glycol, etc. He mea nui ka polyvinyl alcohol. mea hoʻohana kemika i hoʻohana ʻia i ka hana ʻana i nā polyvinyl acetals, nā paipu a me nā vinylans, nā mea lapaʻau lole, nā emulsifiers, nā uhi pepa, nā adhesives, glues, etc.
