Ukucoceka okuphezulu 99% PVP / Polyvinylpyrrolidone
IiNkcazo zeeMveliso
I-PVP (i-polyvinylpyrrolidone) i-polymer e-soluble yamanzi kunye neempawu zokwenza ifilimu. Isetyenziswa kakhulu kwezamayeza (umz. iplasma volume expander okanye contact lens). Ubunzima bemolekyuli yi-K-90 (111.14 g/mol)
Iingenelo
- Iarhente yokutyebisa esebenzayo kunye nefilimu yangaphambili yeejeli zeenwele, izitshizi zeenwele kunye nomgubo oncamathelayo kunye neegel
- Inqanaba lokusetyenziswa lilinganiselwe kuphela yi-viscosity
- I-pH ezinzileyo kakhulu, i-non-ionic kwaye ayinambala
- Eyona nto ingcono xa idityaniswe ne-carbomer okanye ezinye i-thickeners ukunika ukuqina okuqinileyo kwiijeli zeenwele
- Isebenza njenge-disperant ye-titanium dioxide kunye ne-organic pigments
Sebenzisa
Inqanaba lokusetyenziswa okuqhelekileyo 1-40%, malunga ne-4-7% kwiigels zeenwele. Yongeza kwisigaba samanzi sokuqulunqwa, i-hydrate kwaye udibanise kakuhle. Ukusetyenziswa kwangaphandle kuphela.
Usetyenziso
Iimveliso zokunakekelwa kweenwele, iigels ezenza ifilimu enamathelayo, izithambiso zombala.
