nkhani

Polyvinylpyrrolidone (PVP)，cas number 9003-39-8，pvp ndi polima yopanda ionic yomwe ndi mankhwala abwino kwambiri, ophunziridwa bwino komanso ophunziridwa kwambiri pakati pa ma polima a N-vinyl amide. Yakula kukhala magulu a non-ionic, cationic, anion 3, industrial grade, pharmaceutical grade, food grade 3 specifications, relative molecular mass kuyambira zikwizikwi mpaka zoposa miliyoni imodzi ya homopolymer, copolymer ndi crosslinked polymer series products, ndipo ndi makhalidwe ake apadera kwambiri yakhala ikugwiritsidwa ntchito kwambiri.

Kugwiritsa ntchito PVP n'kofala kwambiri, tikuda nkhawa ndi chitetezo cha kugwiritsa ntchito mankhwala, zotsatirazi kuti zikupatseni nkhani mwatsatanetsatane za nkhani zingapo zomwe tikuda nkhawa nazo kwambiri.

Kodi polyvinylpyrrolidone ndi yoopsa?

Polyvinylpyrrolidone ndi mankhwala opangidwa ndi polymer omwe si a ionic, omwe amagwiritsidwa ntchito kwambiri mu mankhwala, chakudya, zodzoladzola ndi zinthu zina, chitetezo chake chimakhala chokwera, ngati awonjezeredwa motsatira miyezo yoyenera, malinga ndi kuchuluka kwa nthawi yogwiritsidwa ntchito, atagwiritsidwa ntchito sadzabweretsa mavuto m'thupi la munthu, palibe vuto lililonse m'thupi la munthu. Muzochitika wamba, polyvinylpyrrolidone si yovulaza thupi la munthu ngati iwonjezeredwa motsatira miyezo yoyenera yowonjezera, koma ngati ipitirira muyezo wachitetezo, ikhoza kukhala yovulaza.

PVPIli ndi mphamvu yabwino kwambiri ya thupi, siigwira ntchito mu kagayidwe ka thupi la munthu, imagwirizana kwambiri ndi zinthu zina, ndipo kwenikweni siimayambitsa kuyabwa pakhungu la munthu, maso ndi nembanemba ya mucous. Chifukwa chake, ingagwiritsidwe ntchito ngati guluu, chotsukira poizoni komanso chosungunulira m'munda wamankhwala. PVP yokha ilibe mphamvu ya khansa, ndipo imatha kupanga zinthu zosakanikirana ndi mankhwala a polyphenol monga tannins. Ingagwiritsidwe ntchito ngati chotsukira komanso chokhazikika cha mowa ndi madzi, ndipo m'munda wa zodzoladzola, ingagwiritsidwenso ntchito pazinthu zosamalira khungu monga zoteteza ku dzuwa, zomwe zingathandize kunyowetsa ndi kudzola. Bola ngati zikugwirizana ndi miyezo yoyenera yadziko lonse kuwonjezera zinthu zokhudzana ndi PVP, chitetezo chachikulu, palibe zotsatira zoyipa zodziwika bwino pa thupi la munthu.

Polyvinylpyrrolidone ingagwiritsidwenso ntchito ngati milomo, mithunzi ya maso, mascara ndi zina zokongoletsa, kuchepetsa utoto ndi zina mwa zinthu zomwe zimapangitsa kuti khungu lizipsa komanso poizoni, kirimu wometa wokhala ndi polyethylpyrrolidone ukhoza kupangitsa kuti ndevu zifewetse komanso kuti mafuta azigwira ntchito bwino, kuwonjezera polyethylpyrrolidone muzopangira utoto wa tsitsi kumatha kusintha mtundu, ndikuwonjezera kulimba kwa utoto. Kuwonjezera polyvinylpyrrolidone ku mankhwala otsukira mano kumatha kuletsa mapangidwe a tartar ndi miyala.

Kodi polyvinylpyrrolidone ndi yotetezeka pakhungu?

Popeza PVP ili ndi poizoni wochepa kwambiri komanso ili ndi vuto lalikulu la thupi, ilibe kuyabwa pakhungu ndi maso, imagwiritsidwa ntchito m'njira zosiyanasiyana mu zodzoladzola. Ntchito ya polyvinylpyrrolidone mu chigoba cha nkhope: kufulumizitsa kulowa kwa zosakaniza, chothandizira kusunga tsitsi, kuchepetsa kuyabwa kwa mankhwala, komanso chitetezo chabwino cha chakudya. Polyethylpyrrolidone ili ndi mphamvu yabwino pakhungu, imapanga filimu yosabisala pakhungu, imagwira ntchito yonyowetsa ngati emollient, ikawonjezera polyethylpyrrolidone ku chigoba, kumverera kwa mafuta kudzachepa, kufewa ndi kusalala kudzakhala bwino, polyethylpyrrolidone imatha kufulumizitsa kulowa kwa zosakaniza za chigoba ndikuwonjezera nthawi yokhalamo kwa zosakaniza.

Kodi polyvinylpyrrolidone ndi yabwino kwa tsitsi?

Polyvinylpyrrolidone monga zodzoladzola zopangira, ndikofunikira kugwiritsa ntchito ngati chothandizira kusunga tsitsi, ili ndi zinthu zambiri zabwino kwambiri, ndi chinthu chofunikira kwambiri popanga tsitsi lopaka, kirimu wa tsitsi, mousse, polyethylpyrrolidone ili ndi mawonekedwe abwino opangira filimu, imatha kupanga filimu yowonekera bwino, imakhala ndi mphamvu yabwino, yosavuta kusungunuka ndi madzi, palibe kuyabwa, palibe ziwengo, ndipo imateteza tsitsi bwino. Ndi chothandizira kukonza komanso chothandizira kupanga filimu pazinthu zosamalira tsitsi monga mousse ndi gel ya tsitsi. Polyvinylpyrrolidone imalumikizidwa ku tsitsi kuti ipange filimu yosaoneka, kukonza kalembedwe ka tsitsi, kulipangitsa kukhala lolimba, kukhala lowala komanso losapanda fumbi. Tsitsi likasambitsidwa, limatha kupesedwa ndikupangidwanso. Likasagwiritsidwa ntchito, limatha kutsukidwa ndi shampu.

Zomwe zili pamwambapa zikunena za ngatiPVPNdi otetezeka, ndikukhulupirira kuti nkhaniyi ingakuthandizeni. Ndife akatswiri opanga ma pvp omwe akhala akugwira ntchito yopanga kwa zaka zoposa 10. Ngati muli ndi mafunso, chonde titumizireni uthenga.
