Saib xyuas
biomass polyvinyl cawv (pva) yog cov tsis muaj tshuaj lom, tsis muaj ntxhiab thiab yooj yim degradable dej-soluble polymer ua los ntawm yas acetate los ntawm polymerization thiab alcoholysis. pva aqueous tov muaj zoo zaj duab xis-tsim, adhesion, emulsification. Cov zaj duab xis tsim tau zoo heev adhesion, hnyav kuj, kev sib txhuam tsis kam thiab oxygen barrier zog, thiab muaj ob qho tib si hydrophilic thiab hydrophobic functional pawg, yog li nws muaj interfacial kev ua si, thiab yuav siv tau raws li ib tug tiv thaiv colloid thaum lub sij hawm polymer emulsification thiab suspension polymerization.
