Qhov txawv yog solubility thiab miscibility. Polyvinylpyrrolidone yog ib tug polymer ntawm vinylpyrrolidone nrog sib txawv molecular luj. Nws yooj yim soluble hauv dej thiab tsis dhau electrolysis. Nws cov tshuaj aqueous yog miscible nrog cellulose series daws. Nws tuaj yeem raug tov nrog nonionic, anionic lossis cationic Cheebtsam xws li salicylic acid. PVPK series cov khoom lag luam tuaj yeem daws tau los ntawm kev ntxiv ntsev ntau, thiab K90 yooj yim dua los kho dua K17. Solubility ntawm PVP nyob rau hauv cov organic solvents sib txawv heev.
PVPK series tuaj yeem yaj hauv cov kuab tshuaj no kom tau txais cov tshuaj uas muaj tsawg kawg yog 10% PVP. Cia ruaj khov Thaum tus nqi pH ntawm cov tshuaj aqueous siab dua 6, nws yuav nce thaum khaws cia ntawm qhov kub siab dua. Acidified tov (concentration tsawg dua 30%) muaj ib tug nyiam agglomerate thaum lub sij hawm cia, uas yuav tiv thaiv tau los ntawm kev ntxiv stabilizers. Nws tsis pom zoo kom siv OH lossis NH2 stabilizers.
Daim ntawv thov: Suspending tus neeg saib xyuas, dispersing tus neeg sawv cev, emulsifier Ntxiv PVPK rau dej-soluble suspending tus neeg saib xyuas, dispersing tus neeg sawv cev, ib tug emulsifier yuav ua rau kom stability. PVP tuaj yeem tsim cov txheej nyias nyias ntawm cov khoom colloid, uas tuaj yeem zam nws cov condensation. Kev tsim cov yas Hauv kev tsim cov khoom siv yas polymers, PVPK tau ntxiv los ua kev tiv thaiv colloid thiab polymerization stabilizer. Adhesives PVPK 90 thiab K 85 yog cov thickeners thiab thickeners rau sodium stearate adhesives. PVPK sib txawv tuaj yeem sib xyaw kom tau txais cov viscosity haum. Nyob rau hauv cov nplaum dispersion, PVP K kuj yog siv los tiv thaiv colloid thiab thickener. PVP K kuj tseem siv los ua cov kua nplaum ntub dej rau kev sib khi cov nyiaj thiab lub hnab ntawv vim tias PVP yog soluble hauv dej.
