I-Polyvinyl Alcohol Umfanekiso obonakalisiweyo

Utywala bePolyvinyl

Inkcazelo emfutshane:

I-Polyvinyl alcohol yi-organic compound, i-chemical formula yi [C2H4O]n, inkangeleko yiflake emhlophe, i-flocculent okanye umgubo oqinileyo, ongenavumba. Inyibilika emanzini (ngaphezu kwe-95℃), inyibilika kancinane kwi dimethyl sulfoxide, ayinyibiliki kwipetroli, kwikerosene, kwioli yemifuno, benzene, toluene, dichloroethane, carbon tetrachloride, acetone, ethyl acetate, methanol, ethylene glycol, njl. Imichiza ekrwada yezinto ezisetyenziswa ekwenzeni ii-acetal zepolyvinyl, imibhobho enganyangekiyo kwipetroli kunye neevinyl, iiarhente zonyango lwelaphu, ii-emulsifiers, iingubo zephepha, izinto zokuncamathelisa, iglu, njl.
