Carboxymethyl Cellulose In Cosmetics - Polyanionic cellulose (PAC) – Yeyuan Detail:

Polyanionic cellulose (PAC) ke motsoako oa ether o qhibilihang ka metsing o lokisitsoeng ke phetoho ea lik'hemik'hale ea cellulose ea tlhaho. Ke ether ea bohlokoa e qhibilihang ka metsing ea cellulose. Hangata e sebelisoa e le letsoai la sodium 'me e sebelisoa haholo ha ho chekoa oli, haholo-holo liliba tsa metsi a letsoai le ho chekoa ha oli kantle ho leoatle.

1. Mesebetsi ea PAC le CMC lebaleng la oli ke e latelang:
- Seretse se nang le PAC le CMC se ka etsa hore lebota la seliba le be tšesaane le kaka e thata ea sefene e nang le matla a tlase le ho fokotsa tahlehelo ea metsi;
- Ka mor'a ho kenya PAC le CMC seretseng, mochine oa ho cheka o ka fumana matla a tlaase a ho kuta, a etsa hore seretse se be bonolo ho lokolla khase e phuthetsoeng ka ho sona, 'me ka potlako e lahle litšila ka mokoting oa seretse;
- Joalo ka liphahlo tse ling tse emisitsoeng, seretse sa ho cheka se na le nako e itseng ea ho ba teng, e ka tsitsang le ho atolosoa ka ho eketsa PAC le CMC.
2. PAC le CMC li na le ts'ebetso e latelang e babatsehang ts'ebelisong ea sebaka sa oli:
- Boemo bo phahameng ba ho kenya sebaka, ho lumellana hantle ha ho kenya sebaka, viscosity e phahameng le tekanyo e tlaase, ho ntlafatsa ka katleho ts'ebetso ea litšebeletso tsa seretse;
- Ho hanyetsa mongobo hantle, ho hanyetsa letsoai le ho hanyetsa alkali, ho loketse metsi a hloekileng, metsi a leoatle le seretse se nang le metsi a tletseng metsi;
- Kaka ea seretse e entsoeng ke ea boleng bo botle le e tsitsitseng, e ka khonang ho tsitsisa sebopeho sa mobu o bonolo le ho thibela ho putlama ha lerako la shaft;
- E loketse litsamaiso tsa seretse tse nang le taolo e thata e tiileng ea litaba le mefuta e mengata e fapaneng.
3. Litšobotsi tsa ts'ebeliso ea PAC le CMC ho cheka oli:
- E na le bokhoni bo phahameng ba ho laola tahlehelo ea metsi, haholo-holo se fokotsang tahlehelo ea metsi. Ka tekanyo e tlaase, e ka laola tahlehelo ea metsi ka tekanyo e phahameng ntle le ho ama thepa e meng ea seretse;
- E na le ho hanyetsa mocheso o motle le ho hanyetsa letsoai ka ho fetisisa. E ntse e ka ba le bokhoni bo botle ba ho fokotsa tahlehelo ea metsi le rheology e itseng tlas'a motsoako o itseng oa letsoai. The viscosity e batla e sa fetohe ka mor'a ho qhibiliha metsing a letsoai. E loketse ka ho khetheha bakeng sa ho cheka lebōpong la leoatle le liliba tse tebileng;
- E ka laola hantle rheology ea seretse mme e na le thixotropy e ntle. E loketse seretse sefe kapa sefe se nang le metsi ka metsing a hloekileng, metsi a leoatle le brine e tletseng metsi;
- Ho feta moo, PAC e sebelisoa e le mokelikeli o samenteng ho thibela mokelikeli ho kena ka masobeng le ho robeha;
- Mokelikeli oa mochini oa sefa o lokiselitsoeng ka PAC o na le khanyetso e ntle ho 2% ea tharollo ea KCl (e tlameha ho ekeletsoa ha ho lokisoa mokelikeli oa mochine oa khatiso), ho qhibiliha hantle, ho sebelisoa ha bonolo, ho ka lokisoa sebakeng sa marang-rang, lebelo la ho etsa li-gel le matla a matla a ho jara lehlabathe. Ha e sebelisoa ka sebopeho se tlase sa permeability, phello ea eona ea khatiso ea filthara e ntle haholo.
