Hydroxyethylcellulose (HEC) ke polymer e feto-fetohang e sebelisoang haholo liindastering tse fapaneng, haholo lipenteng le lirapeng.
1. Selelekela sa Hydroxyethyl Cellulose (HEC)
Tlhaloso le sebopeho
Hydroxyethyl cellulose ke polima e qhibilihang ka metsing e sa sebeliseng metsi e fumanoang ka ho fetola lik'hemik'hale tsa selulose.Sebopeho sa eona sa lik'hemik'hale se na le likarolo tse pheta-phetoang tsa tsoekere tse hokahantsoeng hammoho, tse nang le lihlopha tsa hydroxyethyl tse hoketsoeng ho tse ling tsa lihlopha tsa hydroxyl ho li-glucose.
sebopeho
Ho qhibiliha ha Metsi: E 'ngoe ea lintho tse ka sehloohong tsa HEC ke ho qhibiliha ha metsi ka tsela e babatsehang, e leng ho etsang hore ho be bonolo ho kenyelletsa metsoako ea metsi.
Thickener: HEC e sebetsa e le motenya o sebetsang hantle, o fana ka taolo ea viscosity lits'ebetsong tse fapaneng.
Lintho tsa ho etsa lifilimi: HEC e na le bokhoni ba ho etsa lifilimi bo thusang ho nts'etsopele ea lifilimi tse khomarelang le tse tšoarellang.
Botsitso: E bonts'a botsitso holim'a mefuta e mengata ea pH le mocheso.
2.Karolo ea HEC ho li-coating formulations
Thickening le rheology taolo
HEC e sebelisoa haholo e le motenya ka har'a litlolo tse thehiloeng metsing.E fana ka viscosity ho pente, e amang phallo ea eona le thepa ea boemo bo holimo.Boitšoaro ba rheological ba liphahlo bo bohlokoa bakeng sa ho sebelisoa habonolo le ho theha liphahlo tse tšoanang.
Ntlafatsa botsitso ba pente
Ho eketsoa ha HEC ho matlafatsa botsitso ba litlolo tsa ho roala ka ho thibela ho tsitsa kapa ho thella.Sena se bohlokoa haholo bakeng sa litlolo tse nang le mebala e mengata ea 'mala, moo ho boloka kabo e lekanang ho ka bang thata.
Sebopeho sa filimi le ho khomarela
HEC e thusa ts'ebetsong ea ho etsa filimi ea ho roala.Polymer e omella ho etsa filimi e khomarelang e fanang ka ho khomarela libakeng tse sa tšoaneng.Sena se bohlokoa bakeng sa ho tšoarella le ho phela nako e telele ha bokaholimo bo pentiloeng.
Ho boloka metsi
Lipenteng tsa ka ntle, HEC e thusa ho boloka metsi le ho thibela pente ho omella kapele.Sena se bohlokoa ho lumella pente hore e theohe hantle le ho qoba mathata a kang matshwao a borashe kapa lirolara.
3. Kopo ea HEC mekhoeng ea ho roala
Mehaho ea Mehaho
HEC e sebelisoa haholo liphahlo tsa meralo, ho kenyelletsa le marako a kahare le kantle.E fana ka taolo ea viscosity, botsitso le bokhoni ba ho etsa lifilimi, e leng se etsang hore e be motsoako oa bohlokoa ho pente ea lebota le li-primer formulations.
liaparo tsa lehong
Liaparong tsa lehong, HEC e thusa ho hlahisa likhahla tse hlakileng le matheba a lehong.E thusa ho fihlela viscosity e hlokahalang bakeng sa ts'ebeliso e bonolo holim'a mapolanka, ho netefatsa hore esita le tšireletso le qetello e boreleli.
Liaparo tsa indasteri
HEC e ka sebelisoa mefuteng e sa tšoaneng ea liindasteri, tse kang liaparo tsa tšepe le tse sireletsang.Lintho tsa eona tsa ho etsa lifilimi le ho khomarela li thusa ho etsa liphahlo tse sa hleng le tse tšoarellang nako e telele.
Enke ea ho hatisa
Ho feto-fetoha ha maemo a HEC ho fetela ho li-inks tsa khatiso, moo e ka sebelisoang e le motenya le ho thusa ho ntlafatsa botsitso ba enke ka kakaretso.Sena se bohlokoa ho fihlela boleng ba khatiso bo tsitsitseng.
Hydroxyethylcellulose e bapala karolo ea bohlokoa indastering ea ho penta le ea ho roala, e fana ka melemo e mengata e kenyelletsang ho tenya, botsitso, ho etsa lifilimi le ho boloka metsi.Ho feto-fetoha ha eona ho etsa hore e be motsoako oa bohlokoa mefuteng e fapaneng ea liphahlo, ho tloha ho tsa meralo ho ea ho liaparo tsa indasteri.Ha thekenoloji e ntse e tsoela pele, tlhokahalo ea li-polymers tse sebetsang hantle le tse ngata tse kang HEC e ka 'na ea eketseha, e leng ho tsamaisang boqapi bo eketsehileng lefapheng la lipente le liphahlo.
