Polyvinylpyrrolidone k30/ PVP K-30 cas 84057-81-8
1) I-PVP ikhona njengomgubo omhlophe, omhlophe omhlophe okanye isisombululo esimanzi.
2) Iyakwazi ukunyibilika emanzini kunye neentlobo ezahlukeneyo ze-solvents eziphilayo.
3) Ine-hygroscopicity elungileyo, isakhono sokwenza ifilimu, isakhono esinzima kunye nokuhambelana kwe-physiology.
Amachiza:
IPovidone K30 yinto entsha kunye negqwesileyo yokuncedisa amayeza. Isetyenziswa ikakhulu njengesibophelelo kwithebhulethi, umncedisi wokunyibilika wenaliti, umncedisi wokuqukuqela we-capsule, i-dipersant yeyeza elingamanzi kunye ne-stain, i-stabilizer ye-enzyme kunye neyeza elibuthathaka lobushushu, i-coprecipitant yamachiza anganyibiliki kakuhle, i-lubricator kunye nomncedisi we-antitoxic weyeza lamehlo. I-PVP isebenza njengabancedisi kumachiza angaphezu kwekhulu.
Izithambiso:
I-PVP-K30 ingasetyenziswa njenge-ejenti yokwenza ifilimu, i-viscosity-enhancement agent, i-lubricator kunye ne-adhesive. Ziyinxalenye ephambili yezitshizi zeenwele, imousse, iigels kunye neloshini kunye nesisombululo, ireagent yokufa kweenwele kunye neshampu kwiimveliso zokhathalelo lweenwele. Zingasetyenziswa njengomncedisi kwiimveliso zokhathalelo lwesikhumba, izithambiso zamehlo, i-lipstick, i-deodorant, i-sunscreen kunye ne-dentifrice.
Ezinye izinto eziluncedo:
I-K30 ikwasetyenziswa njengomncedisi. Njenge-disperant kwigraphene kunye ne-carbon nanotubes. Njenge-ejenti eyenza i-pore ye-ultrafiltration membrane, enye intsimi efana nePeyinti kunye neNgqungquthela, iiPlastiki kunye ne-Resin, i-Adhesives, i-Glass Fiber, ifilimu, i-Ink, i-Detergent, i-Tabulating, i-Lapstile Dying kunye noShicilelo, njl.
