Kodi Polyvinylpyrrolidone PVP Series PVP K12 K15 K17 K25 K30 K60 K90 ndi chiyani?

Ufa kapena madzi oyeretsedwa, osungunuka m'madzi, mowa, amine ndi ma hydrocarbons a halogenated, osasungunuka mu acetone, ether, ndi zina zotero. Ali ndi kusungunuka kwabwino kwambiri, kuyanjana ndi zamoyo, kusagwira bwino ntchito kwa thupi, kupanga filimu, kuteteza nembanemba komanso kuthekera kophatikiza mitundu yosiyanasiyana ya mankhwala achilengedwe ndi osapangidwa. Ndi yokhazikika ku asidi, mchere ndi kutentha, kotero imagwiritsidwa ntchito mosiyanasiyana.

Kugwiritsa ntchito

Polyvinylpyrrolidone imagwiritsidwa ntchito kwambiri m'munda wa zamankhwala ndipo ndi imodzi mwa zinthu zitatu zatsopano zogwiritsira ntchito mankhwala zomwe zimalimbikitsidwa padziko lonse lapansi. Ma glue omwe amagwiritsidwa ntchito kwambiri ndi mapiritsi ndi granules. Ingagwiritsidwenso ntchito ngati chothandizira kuyenda kwa makapisozi, kuchotsa poizoni m'thupi ndi mafuta opaka m'maso, chosungunulira pamodzi jakisoni, chosungunulira madzi okonzekera, komanso chokhazikika cha ma enzyme ndi mankhwala omwe amakhudzidwa ndi kutentha. Povidone ikhozanso kupangidwa ndi mankhwala ophera tizilombo toyambitsa matenda a iodine povidone iodine (PVP-I). Mu ma contact lens, PVP imagwiritsidwa ntchito ngati gawo la ma contact lens kuti awonjezere hydrophilicity yawo. PVP ingagwiritsidwenso ntchito ngati cryogenic preservative mu mankhwala.
