Pombe ya polyvinyl (PVA) Wanwei

Maelezo Fupi:

Pombe ya polyvinyl ni mchanganyiko wa kikaboni na fomula ya kemikali ya [C2H4O] n.muonekano wake ni flake nyeupe, flocculent au unga imara na dufu.Mumunyifu katika maji, mumunyifu kidogo katika dimethyl sulfoxide, hakuna katika petroli, mafuta ya taa, mafuta ya mboga, benzini, toluini, dikloroethane, tetrakloridi kaboni, asetoni, ethyl acetate, methanoli, ethilini glikoli, nk. Pombe ya polyvinyl ni malighafi muhimu ya kemikali, ambayo hutumika kutengeneza asetali ya polyvinyl, bomba linalokinza petroli na vinylon, wakala wa matibabu ya kitambaa, emulsifier, mipako ya karatasi, wambiso, gundi, nk.
