IPolyvinylpyrrolidone
Polyvinylpyrollidone (PVP) Iimveliso zeBanga lobuGcisa zikhona njengomgubo nefom yesisombululo samanzi, kwaye zinikezelwa kuluhlu olubanzi lobunzima beemolekyuli, zinyibilika ngokulula emanzini, etywaleni nakwezinye izinyibilikisi zendalo. uzinzo lwekhemikhali, akukho netyhefu. Iiparameter zobuchwephesha eziphambili: Imveliso PVP K15P PVP K17 PVP K25 PVP K30 PVP K90 PVP K30L PVP K85L PVP K90L Inkangeleko emhlophe okanye emhlophe umgubo ongenambala ongenambala u-yellowis ... -
IVinylpyrrolidone / IVinyl Acetate
I-VP / VA Copolymers zinemilinganiselo eyahlukeneyo ye-vinylpyrrolidone ukuya kwi-acetate ye-vinyl kwaye ifumaneka njengempuphu emhlophe okanye izisombululo ezicace gca emanzini, i-ethanol kunye ne-isopropanol. kunye nesinyithi, ezi propati, kunye nokukwazi ukulawula i-hydrophilicity yazo ngokubunjwa kwe-monomer, zikhokelela ekusebenziseni kwayo ngokubanzi kwimizi-mveliso. Iiparamitha zoBugcisa eziPhambili: Imveliso PVP / VA 64 Powder PV ... -
PVPP
I-PVPP yi-PVP enqamlezileyo, iyi-hygroscopic, engenakunyibilika emanzini kunye nazo zonke ezinye izinyibilikisi eziqhelekileyo, kodwa iyadumba ngokukhawuleza kwisinyibilikisi esinamanzi ngaphandle kwejeli. Iiparamitha zoBugcisa eziPhambili: Imveliso ye-PVPP (iNdlela enye) I-PVPP (iphinda ihlaziyeke) Inkangeleko emhlophe ukuya kumhlophe, i-hygroscopic, umgubo ohamba ngokukhululekileyo Umnyibilikisi ongenakunyibilika emanzini kunye nezinye izinyibilikisi eziqhelekileyo. Ivumba lokumiswa kwetyhefu, i-Nitrogen Eqhelekileyo 11.0-12.8% 11.0-12.8% Isinyithi esinzima (njenge-Pb) 10ppm max. Ubukhulu be-10ppm. Khokela 2 ppm max. 2 ppm ubuninzi ...
