Thepa le ts'ebeliso ea hydroxethyl celdoulose (hec)

1. Thepa ea hydroxethyl cellulosese
Hydroxethyl Cellulose Sebopeho sa eona se entsoe ka likarolo tsa glucose tse amanang le maqhama a β-1,4-glycsidic. Lihlopheng tsa hydroxethyl (-ch2chHohh) li kenngoa limolek'hule tsa hydrowexeyl, tse kopanyang lihlopha tsa hydroyl tsa celdroyl lihlekehlekeng tsa lik'hemik'hale. Ka lebaka la phetoho ena, Hec o na le thepa e ngata e fapaneng le cellulose ea pele.

LITLHAKISO TSA 'Mele
Ponahalo: Hangata hec hangata ke phofo ea amorphous e tšoeu e nang le phofo e ntle.
SELLE: Hec e ea lieha habonolo metsing, haholo metsing a batang, a etsa tharollo ea viscous. Sena se bakoa ke ho tlala hydrojene pakeng tsa sehlopha sa hydroythl le limolek'hule tsa metsi, tse nolofalletsang HC li hasana ka matla metsing.
Viscosity: Tharollo ea Hcc ka metsing e bonts'a liketsahalo tse phahameng, 'me pono e amana haufi le boima ba limok'hule le khatello ea maikutlo. Ka kakaretso, pono ea Hec e eketseha ka keketseho ea boima ba moleng.
Ho tsilatsila mocheso: Hec ho na le botsitso bo botle ba mafura mme ba khona ho boloka sekoli se tiileng ka mocheso o itseng. Ka kakaretso, Hec o khona ho mamella mocheso o phahameng, empa ts'ebetso ea ona e tla fokotseha kamora ho feta mocheso o itseng.

Li-commituri tsa lik'hemik'hale
Ts'ebetso ea pele: Sehlopha sa Hydroyll ho Hec Molek'hule ke hydrophilic, e lumellang hore e thehe tharollo e tsitsitseng ea metsi le ho ntlafatsa tšebetso e ka tlase.
Ho nepahala: Ka ho fetola maemo a hau a ho arabela, boima ba moleng, ancel, vission le thepa e 'ngoe ea hec e ka fetoloa ho fihlela litlhoko tse fapaneng tsa ho sebetsa.
PH botsitso: Hec e tsitsitse tikolohong e sa nke lehlakore kapa e fokolang, empa e ka ama maemo a matla a acidic kapa a alkaline.

2. Lipere tsa hydroxethyl cellulosese
Ka lebaka la thepa ea eona e mengata e ntle ea hec e sebelisoang haholo masimong a fapaneng. Mesebetsi e ka sehloohong e kenyelletsa likarolo tse latelang:

Indasteri ea kaho ea khoebo ea kaho, hec e sebelisoa e le molaoli ea ho atisa ho eketsoa, ​​haholoholo ka samenteeng, li-gypsis, likhakanyo le lihlahisoa tse ling. Hec a ka ntlafatsa phetoho e feto-fetohang, phokotso le ts'ebetso ea lisebelisoa tsena. Ntle le moo, hec e ka ntlafatsa ho boloka metsi a sere, ho holisa nako ea ho haha, ho holisa le qoba ho lula kapele. Ka lebaka la thepa ea eona e tobileng, hec e khona ho ntlafatsa tšireletso le ho ba le kamano ea boqapi ba meralo.

Liikela tsa lik'hemik'hale tsa letsatsi le letsatsi tsa lik'hemik'hale tsa letsatsi le letsatsi tsa lik'hemik'hale, Hec li sebelisoa haholo tlhahisong ea litheolelo, li-shampoos, gels gels, litlolo tse hlahang le lihlahisoa tse ling. Karolo ea mantlha ea Hec Lihlahisoang tsena e joalo ka sehlōne, moemeli ea emisang, emmolifier le hlokana. Hec a ka thusa limpho tse bolokang pono e loketseng, fana ka maikutlo a matle a ho sebelisoa, le ho ntlafatsa tsitsipano ea sehlahisoa. Ntle le moo, hec e ka ntlafatsa leloko la Rheology ea litsie ho netefatsa lintho tse tšoanang le katleho nakong ea ts'ebeliso ea tsona.

Indasteri ea lijo Hec e sebelisoa e le bolotsana, e hlohlelletsang le emulifier indastering ea lijo, haholo-holo indastering ea lijo, haholo lijong tse kang ice cream, lero, li aparetse likhohlano le liaparo tsa motho. Hobane Hec o na le alloudity ea metsi a metsi, e ka ntlafatsa tatso le sebopeho sa lijo, e eketsa maemo, ho ntlafatsa phallo ea lijo, le ho holisa bophelo ba lijo.

Liiporiti tsa pharmacecticatical indastering ea meriana, Hec e sebelisoa haholo e le motho ea tsamaisang thepa, emulifier, khomare le thickener bakeng sa lithethefatsi. E sebelisoa ho pheha lithethefatsi tsa molomo, li-gelts, marotholi a mahlo, hec li ka laola sekhahla sa lithethefatsi, li netefatsa semelo sa lithethefatsi, le ho ntlafatsa phano ea lithethefatsi.

Phepelo ea temo Hec e sebelisoa haholo temong e le moemeli oa ts'ireletso ea semela, a emolsite emulfied le manyolo bolokolohi. E ka ntlafatsa ho lahla lintho tse sa laoloeng ke tšitiso ho mela le ho ntlafatsa ho halefisoa ke meriana e bolaeang likokonyana. Ka nako e ts'oanang, hec e ka ntlafatsa botsitso ba manyolo, ba fokotsa tahlehelo ea manyolo mobung, mme o ntlafatsa katleho ea manyolo.

Indasteri ea Petroleum e bapala karolo ea bohlokoa indastering ea Petrolium, haholo-holo ka lik'hemik'hale tsa oli tsa oli. E sebelisoa e le bolo ea thipa, e emisang le seliba. Hec a ka eketsa pono ea ho noha le ho ntlafatsa matla a lino tse nkileng metsi, e le hore a ka nka mekhabiso e hlahisoang nakong ea ho cheka. Ka nako e ts'oanang, hec e ka thibela ho loha ka liliba lilibeng tsa oli le tsa khase nakong ea ho chechisa ho netefatsa tsoelo-pele ea ts'ebetso.

Hydroxethyl cellulosese (Hec) ke thepa ea polymer e qhibilihileng ka metsi e nang le ts'ebetso e ntle haholo. Matlafatso ea eona e ikhethang, botsitso le alloubility ea metsi a mangata li ka etsa hore e sebelisoa haholo indastering e ngata e kang kaho, lijo-thollo, temo, temo. Ka nts'etsopele ea theknoloji, ts'ebetso ea tlhahiso le taolo ea ts'ebetso ea Hec e tla tsoela pele ho ntlafatsa, le tebello ea eona ea ho etsa kopo e tla ba e pharaletseng.
