* Ukuvinjelwa kokudayi kokuhlanza usebenzisa i-PVP K15, K17 & K30 kanye / noma umkhiqizo wayo oketshezi kumbaleki oyinkimbinkimbi.
* Ukwehliswa kukadayi wezindwangu nokulawulwa kwezinga lesiteleka ngokuhlanganiswa nokusakazeka nge-PVP K30 kanye / noma umkhiqizo wayo oketshezi.
* Izisetshenziswa zokuwasha lapho i-PVP K30 ivimbela ukubekwa kabusha kwenhlabathi.
* I-Emulsion polymerization lapho i-PVP K30 kanye noma i-latex product product stabilizer yayo, esebenza njenge-colloid evikelayo, isiza ukusatshalaliswa kabusha kohlelo lokusebenza 'lokuphuka' kwe -latex.
* Ukuhlakazeka kusetshenziswa i-PVPK30 & K90 kanye / noma umkhiqizo wayo ketshezi wedayi engabonakali nezinhlelo zokubhala ezincike kumbala.
* Ukwenziwa kolwelwesi lwe-fiber olungenalutho lapho i-PVP K90 ne-K30 kanye / noma umkhiqizo wayo oketshezi udala ize noma iziphi izizinda ze-hydrophilic ezingxenyeni zepolysulfone.
* Kumafayili afakwa usimende, lapho i-PVP K30 ne-K90 kanye noma imikhiqizo yayo engamanzi igcina njengama-ejenti wokulawula uketshezi.
* Kumapuleti e-lithographic asebenzisa uyinki we-hydrophobic, lapho i-PVPK15 inikeza khona ukuthuthukiswa kwendawo engeyona eye -image.
* I-PVP K80, i-K85 ne-K90 kanye / noma imikhiqizo yayo ewuketshezi ezintweni zokubambelela ezisuselwa ku-stearate zezicelo zobuciko nobuciko.
* Ku-fiber glass sizing, usebenzisa i-PVP K30 & K90 kanye / noma imikhiqizo yayo yefilimu eyenza isenzo ukukhuthaza ukunamathela kwe-polyivnylacetate.
* Njengezibopho ze-ceramic ezivuthayo, zisebenzisa i-PVP K30 & K90 kanye / noma umkhiqizo wayo oketshezi ukukhulisa amandla aluhlaza.
* I-PVP K15, K17, K30, K60 & K90 kanye / noma imikhiqizo yayo ewuketshezi esetshenziswa kwezolimo njenge-binder kanye ne-complexation agent yokuvikela isivuno, ifilimu eyiPrimary eyake yenziwa ekwelashweni kwembewu nokumbozwa.
