Hc (hydroxeeyyl cellulolose) le hydroxypropypropypropy Lisebelisoa tsena e se e le lisebelisoa tsa bohlokoa tse sebetsang ka lebaka la thepa ea tsona e ikhethang ea 'mele le ea lik'hemik'hale.
1. Hec (hydroxethyl cellulolose)
1.1 Sebopeho sa mantlha le thepa
Hec ke polymer ea se nang moea e qhibilihang ea metsi e fumanoeng ke ho fetoloa ha lik'hemik'hale tsa celluulose ea tlhaho. Sebopeho sa eona sa mantlha ke kenyelletso ea hydroxethyl Strautuens on the β-D-Glucose Skeleton ea Cellulose. Ka lebaka la hydrophphilicity ea sehlopha sa hydroxethl se hlaha, Hec o na le thepa e ntle le e tona e khabisitsoeng ka metsing.
Hec o bonts'a hodhesion e ntle, ho theha filimi le lubrinition le makhopho le Alkali ebile e na le biocondomatic hantle. Botho bona bo e etsa eneckener e sebetsang haholo, e hlohlelletsang le moemeli ea etsang lifilimi se tsamaeang le lifilimi. Ntle le moo, tharollo ea Hec e na le thixotta eaxottapy, e ka bonts'a pono e phahameng tlasa matla a tlase, 'me viscosity e theoha ka potlako tlasa sesole se phahameng. Tšobotsi ena e etsa hore e be le boleng ba bohlokoa kalafong e fapaneng ea mokelikeli.
1.2 Ts'ebetso ea boitokiso
Hec e itokisetsa haholo ho etsa qeto ea hore na ho chesoa ke conly conly. Hangata thepa e tala e sebelisoang e kenyelletsa mehloli ea nonyana e kang k'hothone le lehong e amohelang khomo ea ethylene kamora ho amohela hydroxethyl cellulose. Nakong ea maikutlo ohle, taolo ea maemo a ho etsa (boleng ba PH le nako ea PH) e na le tšusumetso ea bohlokoa ho degree ea sebaka sena.
Mekha ea kopo ea 1.3
Hec e sebelisoa haholo ka thepa ea moaho, makhapetla, lik'hemik'hale tsa letsatsi le letsatsi, bongaka le lijo. Sebakeng sa moaho, Hec e sebelisoa ka bongata Sertan le Gypsimo e le boloi bo sebetsang le ba hlolloang ho ntlafatsa ts'ehetso ea eona le e thibelang. Indastering ea Coatiking, Hec e ka sebelisoa e le Morifier ea thipa le Rheology bakeng sa likariki tse thehiloeng metsing ho ntlafatsa khokahano le boreleli ba likokoana-hloko. Lik'hemik'heise tsa letsatsi le letsatsi tse kang shampoo le senitizer ea letsoho le matsoho, Hec e sebelisoa e le thipa le mongobo ho fa sehlahisoa le botsitso. Ntle le moo, indastering ea meriana le ea lijo, HC e sebelisoa e le mokhoa oa matlapa, filimi e kileng ea sebetsa bakeng sa lijo, le lehloeo la lijo tse ntle le chefo e tlase.
2. Hpmc (hydroxypropypropyl methylcell)
2.1 Sebopeho sa mantlha le thepa
HPMC ke e se nang leeme e fumanoeng ka ho hlahisa hydroxypropyl le mekhoa ea metho skeleton. Hoa tšoana le ka HC, HPMC e na le solo e ntle ea metsi, e meholo, filimi e theha thepa le senoelo. Ka lebaka la lihlopha tsa Methoy le hydropyl
Visicosity ea tharollo ea HPMC e angoa haholo ke mocheso. Ka lebaka la mocheso o itseng, incosture ea tharollo ea HPMC e fokotseha ka mocheso o ntseng o eketseha. Ntle le moo, HPMC e boetse e na le thepa e ntle ea lihlahare. Ha mocheso oa tharollo o feta boleng bo itseng, gel e tla thehoa. Thepa ena e na le boleng bo khethehileng ba kopo libakeng tsa lijo le meriana.
2.2 Ts'ebetso ea Boitokiso
Ho hlophisoa ha HPMC le tšoana le HC, 'me le boetse le etsoa ho fihlela karabelo ea malinyane a cellulose. Hangata, karabelo ea celllyulose le methyl chloride ea alkaline ea alkaline ho hlahisa li-hydroxypropyl le methong. Thepa ea hpmc (joalo ka viscosion, mocheso le gel) o ka laoloa hantle ka ho fetola maemo a nkang sebaka.
2.3 LITLHAKISO TSA BOTSOANG
HPMC e na le lits'ebetso tse fapaneng tsa lits'ebetso tsa lits'ebetso tsa lits'ebeletso, meriana, lijo le lik'hemik'hale tsa letsatsi le letsatsi. Lisebelisoa tsa moaho, HPMC e sebelisoa haholo ka har'a lihlahisoa tsa sere sa samer le tsa gypsum e le thipa, ea ho boloka metsi le mokhoa oa ho ntlafatsa ts'ebetso ea kaho le mokhoa oa ho ntlafatsa ts'ebetso ea kaho le ho tšoarella ha thepa. Tšimong ea bongaka, HPMC e sebelisoa e le moemeli oa tokiso ea matlapa, o ka laolang sekhahla sa lithethefatsi le ho ntlafatsa botsitso ba lithethefatsi. Indastering ea lijo, HPMC e sebelisoa haholo joalo ka thipa le emumolier ka thepa e halikiloeng, lihlahisoa tsa lebese le liishene ho ntlafatsa sebopeho le tatso ea lihlahisoa. Ntle le moo, HPMC e boetse e sebelisoa haholo ka lik'hemik'hale tsa letsatsi le letsatsi tse kang shampoo, setsebi sa kelello, se hloekisang thepa ea librication.
E le Dielbodase ea Bohlokoa ea Bohlokoa, Hec le HPmc ba bapala karolo ea bohlokoa indastering e ngata. Hec e sebelisoa haholo ho ea kaho, likomiti tsa letsatsi le letsatsi le tsa bongaka ka lebaka la ho etsa menoana e ntle, ho etsa biocondomatic. Ka lehlakoreng le leng, HPMC, e bapala karolo ea bohlokoa ho ea khoebong ea bongaka le ea lijo ka lebaka la thepa ea eona e ikhethang ea likopo. Ka tsoelo-pele ea theknoloji, ts'ebetso ea tokiso le likarolo tsa lits'ebetso tsa lisebelisoa tsena tse peli li tla tsoela pele ho hola, ho tlisa menyetla ea indasteri e amanang le.
