Hydroxethyl cellulose

Hydroxeeyl cellulouse: Kakaretso
Hydroxethyl celdlouseyey Ka lebaka la thepa ea eona e khethollang, e leng Hec e se e sebelisetsoe indasteri e seng ea bohlokoa, ho kenyelletsa merafo, litlolo, lipere le kaho.

Synthesis ea hydroxethyl celluloulose
Ho hlahisoa ha Hec ho kenyelletsa hore e ntlafalitsoe ea cellulose. Ts'ebetso ena e qala ka cellulose e tšoaroang ka sodium hydroxide ho hlahisa alkali cellulose. Ebe u kenngoa ka sekoli hona joale, se fella ka sebopeho sa hydroxethyl celdoulose. Karabelo e ka emeloa tjena:

Cellulolose-aa + nch2ch2o → cellulose-och2chhh

Degree of DS DS e bua ka palo ea li-hydroxyl molek'huleng ea selefouno e neng e nkeloa sebaka sa methapo ea lilemaneng ea Ethylene ka glucose yuniti ea glucose ea cellelose. Paramente ena e susumetsa sello, se utloang le thepa e 'ngoe e sebetsang ea Hec.

Hec o na le thepa e mengata e ikhethang:

SELLE: Hec e qhibiliha metsing a chesang le a batang, a etsang hore e qaqhele likopo tse fapaneng. E ka theha tharollo e hlakileng, e boima e tsitsitseng ka bongata bo boholo.

Ke pono: Ke pono ea tharollo ea hec e itšetlehileng ka boima ba eona ba limoele le mahloriso. Hec a khona ho hlahisa li-viscosion tse fapaneng, ho li etsa tse sebetsang lits'ebetsong tse hlokang litšobotsi tse khethehileng tsa phallo.

Bokhoni ba ho etsa lifilimi: Hec a ka theha lifilimi tse feto-fetohang, tse hlakileng. Thepa ena e na le thuso e khethehileng ho bakoang le litlolo.

Moemeli oa Thickening: Hec ke moemeli ea atlehang ea toackening, o fana ka botsitso le botsitso ho liforomo.

Bokhopo: Hec e tsitsitse ebile e hanyetsoa ke litšila ka leseli, mocheso le likokoana-hloko tse telele tsa likopo tse fapaneng.

Likopo tsa Hydroxethyl celluloulose
Ka lebaka la thepa ea hae e ikhethang, Hec e fumana likopi masimong a mangata:

Meriana: indastering ea meriana, hec e sebelisoa e le moetsi oa chelete, oa pele le moea o matla le metso e matlaleng. E thusa ho lokolloa ha lithethefatsi tse laoloang le ho ntlafatsa bongoana le botsitso ba liforomo.

Li-cosmetics: Hec e sebelisoa litlhophisong tsa tlhokomelo ea motho joalo ka shampoos, loution le litlolo. E fana ka pono e lakatsehang, e ntlafatsa maikutlo a sehlahisoa, mme o tiisa emulsions.

Li-peta le lipuisano: indastering ea penta, Hec e sebetsa e le boloi, se hlolla le moemeli oa ho boloka metsi. E ntlafatsa thepa ea kopo ea pente, ho thibela ho ja, 'me u hlahise ho theha baesekopo.

Kaho: Hec e sebelisoa ka lisebelisoa tsa kaho joaloka samente le samente. E ntlafatsa ho tsoelapele, boloka metsing le ho boloka metsi, ho ntlafatsa ts'ebetso le ho tšoarella ha lisebelisoa tsena.

Indasteri ea lijo: Le hoja a ka sebelisoa e le ntho e tloaelehileng, ea hec e ka sebelisoa e le thipa le e hlonepha lihlahisoa tse itseng tsa lijo, e netefatsa sebopeho se boreleli le se sa lumellaneng.

Indasteri ea maxile: hec e sebelisoa e le moemeli oa ho soasoa indastering ea likhahla, o fana ka matla le botsitso ho yaran nakong ea ho loha.

Tšitiso ea Ts'ireletso le Tikoloho
Hec o ile a nkuoa e sireletsehile bakeng sa lits'ebetso tse fapaneng tsa litsing tse fapaneng, haholo-holo lisopo le litlolo, moo e kileng ea lekanngoa le chefo le ho teneha. Ha se ntho e nang le chefo, e se nang khalefo, le hypoauallergenininininininininiki, e etsa hore e be loketseng tšebeliso ea lihlahisoa kapa e kentsoeng.

Ho tloha ntlheng ea tikoloho, hec e sebetsa hantle 'me e tsoa ho lisebelisoa tse ncha tse nchafalitsoeng (cellulose). Tlhahiso ea eona le ts'ebeliso e amana le tšusumetso e tlase ea tikoloho. Leha ho le joalo, joalo ka lik'hemik'hale tsohle, ho sebetsana le ho sebetsa ka nepo ho hlokahala ho fokotsa likotsi leha e le life tse ka bang tikoloho.

Hydroxethyl Cellulosese ke Polymer ea feto-fetohang le ea bohlokoa e nang le lits'ebetso tse fapaneng tse amanang le indastering e fapaneng. Mekhoa ea eona e ikhethang, joalo ka soudibaulity ea metsi, taolo ea liphio, bokhoni ba lifono le botsitso, e etsa hore e be ea bohlokoa ho pharing ho tloha phamaneng ho ea ho phaello. Morero oa Hec o hlasimolohileng cellulose o emela tšebeliso e sebetsang ea lisebelisoa tsa tlhaho, e kenya letsoho ho tsitsiseng. Ka profilfete e matla ea polokeho le phello e fokolang ea tikoloho, hec e ntse e le motsoako oa bohlokoa lipapatsong tse fapaneng tsa khoebo le tsa indasteri.
