Tšebeliso ea li-cellulose ethers indastering ea ho roala

Liaparo esale e le karolo ea bohlokoa ea liindasteri tse fapaneng, ho tloha ho tsa kaho le tsa likoloi ho ea ho liphutheloana le thepa ea ka tlung. Lipente li sebeletsa merero e mengata e kang mokhabiso, tšireletso, ho hanyetsa kutu le ho boloka. Ha tlhoko ea liphahlo tsa boleng bo holimo, tse tšoarellang le tse bolokang tikoloho e ntse e hola, ts'ebeliso ea li-cellulose ethers indastering ea ho roala e eketsehile.

Li-cellulose ethers ke sehlopha sa li-polymers tse hlahisoang ke phetoho ea lik'hemik'hale tsa cellulose, polymer ea tlhaho e fumanoang marakong a lisele tsa semela. Phetoho ea selulose e lebisa ho thehoeng ha cellulose ethers, e nang le thepa e kang ho qhibiliha ha metsi, viscosity le bokhoni ba ho etsa filimi.

E 'ngoe ea melemo e ka sehloohong ea li-cellulose ethers ke bokhoni ba tsona ba ho sebetsa e le li-thickeners ho li-coating formulations. Ba phetha karolo ea bohlokoa ho finyella viscosity e hlokahalang, ho netefatsa tšebeliso e nepahetseng ea ho roala le ho etsoa ha filimi. Ho phaella moo, ba fana ka thepa e ntlafetseng ea rheological ho liphahlo, tse kang ho laola phallo e ntle le thepa ea boemo.

Ntle le thepa e teteaneng, li-cellulose ethers li fana ka melemo e meng e mengata ho li-coating formulations. Ka mohlala, ba ka ntlafatsa ho khomarela ha liphahlo ho li-substrates, ba ntlafatsa ho thibela metsi ho koahela, 'me ba eketsa nako e telele le ho fetoha ha lifilimi tsa ho roala. Ho phaella moo, li na le monko o fokolang, chefo e tlaase, 'me li lumellana le mefuta e sa tšoaneng ea lisebelisoa tse tala tsa ho roala, ho akarelletsa le li-pigment, li-extensions le li-resin.

Li-cellulose ethers li sebelisoa haholo indastering ea ho roala bakeng sa mefuta e mengata ea tšebeliso, ho kenyelletsa le liaparo tsa meralo, liaparo tsa lehong, liaparo tsa indasteri le li-inks tsa khatiso. Ka liphahlo tsa meralo, li sebelisetsoa ho fihlela ho hanyetsa sag ho hlokahalang, brushability le thepa ea boemo bo holimo. Ho feta moo, li eketsa ho hanyetsa metsi ha liphahlo tsena, tse bohlokoa haholo lits'ebetsong tsa kantle. Lirapeng tsa mapolanka, li fana ka ho khomarela le ho feto-fetoha ho hlokahalang bakeng sa ho pepeseha ka ntle hape li thusa ho sireletsa khahlanong le mahlaseli a kotsi a UV. Liaparo tsa indasteri, li-cellulose ethers li ntlafatsa ho hanyetsa ha li-abrasion tsa liaparo, ho li etsa tse loketseng ho sebelisoa mechine e boima, liphaephe le lisebelisoa. Ka li-inks tsa khatiso, li sebetsa e le li-modifiers tsa viscosity, li ntlafatsa phetisetso ea enke le boleng ba khatiso.

O mong oa melemo e meng ea bohlokoa ea li-cellulose ethers ke botsoalle ba tsona ba tikoloho. Li ka nchafatsoa hape li ka senyeha, 'me li etsa hore e be thepa e tala e tšoarellang. Ho feta moo, li na le tšusumetso e fokolang tikolohong le bophelong ba batho hobane ha li chefo ebile ha li hlahise lihlahisoa tse kotsi nakong ea tlhahiso, tšebeliso kapa ho lahla.

Li-cellulose ethers li fetohile lisebelisoa tsa bohlokoa indastering ea ho roala, e sebeletsa merero e fapaneng e kenyeletsang ho teteka, ho hanyetsa metsi le ho khomarela. Thepa ea eona e babatsehang ea rheological, ho lumellana le lisebelisoa tse ling tsa ho roala le ho tšoarella ho etsa hore e be khetho e khahlehang bakeng sa bahlahisi ba ho roala. Ka bohlokoa bo ntseng bo eketseha ba botsitso le botsoalle ba tikoloho, li-cellulose ethers li kanna tsa ba tsa bohlokoa le ho feta indastering ea liphahlo nakong e tlang.
