I-Polyvinylpyrrolidone
IPolyvinylpyrollidone (PVP) Imikhiqizo yebanga lobuchwepheshe ikhona njengefomu lesisombululo sempuphu namanzi, futhi inikezwa ngobubanzi besisindo samangqamuzana, incibilika kalula emanzini, otshwaleni nakwamanye ama-solvents angokwemvelo. ukuzinza kwamakhemikhali, abukho ubuthi. Amapharamitha Wobuchwepheshe Osemqoka: Umkhiqizo PVP K15P PVP K17 PVP K25 PVP K30 PVP K90 PVP K30L PVP K85L PVP K90L Ukubukeka kwempuphu emhlophe noma emhlophe engenambala engenambala ku-yellowis ... -
IVinylpyrrolidone / iVinyl Acetate
I-VP / VA Copolymers inezabelo ezahlukahlukene ze-vinylpyrrolidone ku-acetate ye-vinyl futhi itholakala njengempuphu emhlophe noma izixazululo ezicacile ezisobala emanzini, i-ethanol ne-isopropanol.Yakha amafilimu anzima, acwebezelayo, aguquguqukayo, asuswayo, futhi asuswa ngama-oxygen amafilimu ahambisana nengilazi, amapulasitiki nezinsimbi, lezi zakhiwo, ezihambisana namandla okulawula i-hydrophilicity yazo ngokwakhiwa kwe-monomer, ziholela ekusetshenzisweni kwayo kwezimboni. Amapharamitha Wobuchwepheshe Osemqoka: Umkhiqizo PVP / VA 64 Powder PV ... -
PVPP
I-PVPP iyi-PVP exhumene, iyi-hygroscopic, ayincibiliki emanzini nawo wonke amanye ama-solvent ajwayelekile, kepha ivuvukala ngokushesha ku-solutbition enamanzi ngaphandle kwe-gel. Amapharamitha Wobuchwepheshe Osemqoka: Umkhiqizo i-PVPP (One Way) I-PVPP (Yenza kabusha) Ukubukeka Okumhlophe kube mhlophe, i-hygroscopic, i-powder egeleza mahhala Ukuncibilika Okungenakunyakaziswa emanzini namanye ama-solvent ajwayelekile. Iphunga elimisiwe lokumiswa, i-Typical Nitrogen 11.0-12.8% 11.0-12.8% Izinsimbi ezisindayo (NjengoPb) 10ppm max. 10ppm ubuningi. Hola 2 ppm max. 2 ppm max ...
