Methylcellulose (MC) ke motsoako oa bohlokoa oa selulose o qhibilihang ka metsing, o sebelisoang haholo mekhoeng e sa tšoaneng ea indasteri, e sebetsa e le motenya, emulsifier, stabilizer, filimi ea pele le lubricant. E fumanoa ka phetoho ea lik'hemik'hale ea selulose, e na le thepa e ikhethang ea 'mele le ea lik'hemik'hale,' me e ka phetha karolo ea bohlokoa likarolong tse fapaneng tsa indasteri, haholo-holo lihlahisoa tsa mohaho, liaparo, lijo, meriana le liindasteri tsa litlolo.
1. Lintho tsa motheo tsa methylcellulose
Methylcellulose ke phofo e se nang 'mala, e sa latsoeheng, e se nang monko kapa granule e monyang metsi a matla le ho qhibiliha hantle. Sehlopha sa methoxy (-OCH₃) se hlahisoa ka sebopeho sa eona sa limolek'hule. Phetoho ena e e fa lintho tse ling tseo cellulose ea tlhaho e se nang tsona, ho kenyelletsa:
Solubility: Methylcellulose e qhibiliha habonolo metsing a batang ho etsa tharollo e hlakileng ea colloidal, empa ha e qhibilihe metsing a chesang, e bontšang litšobotsi tsa thermogel. Thepa ena ea thermogel e etsa hore e be le phello e teteaneng mochesong o itseng le ho boloka botsitso bo botle ba morphological mocheso o phahameng.
Biocompatibility: Kaha methylcellulose e tsoa ho selulose ea tlhaho, ha e na chefo, ha e halefise ebile e ka senyeha habonolo, kahoo e na le botsoalle ba tikoloho.
Ho tiisa le botsitso: Methylcellulose e ka eketsa viscosity ea tharollo ka katleho 'me ea bapala karolo e teteaneng. E boetse e na le botsitso bo botle, bo ka thusang lisebelisoa tse ling ka foromo hore li arolelanoe ka ho lekana le ho li thibela ho lula kapa ho arohana.
2. Tšebeliso ea methylcellulose indastering ea kaho
Ka indasteri ea kaho, methylcellulose e sebelisoa haholo linthong tse kang seretse sa samente, putty powder le lihlahisoa tsa gypsum. Mesebetsi ea eona ea mantlha e kenyelletsa:
Thickener: Ka seretse sa samente, methylcellulose e eketsa viscosity, e ntlafatsa ts'ebetso le ts'ebetso ea seretse, e nolofatsa ho hahoa, 'me e ka thibela ka katleho ho phalla ha metsi le stratification. E etsa hore seretse se be le mokelikeli haholoanyane le mokhoa oa ho haha o be bonolo.
Moemeli oa ho boloka metsi: Methylcellulose e na le thepa e ntle ea ho boloka metsi, e ka liehisang tahlehelo ea metsi ka seretseng le ho lelefatsa nako ea hydration ea samente, kahoo e ntlafatsa phello ea kaho le matla. Maemong a leholimo a omileng, methylcellulose e ka fokotsa mouoane oa metsi le ho thibela ho phatloha ha seretse.
Anti-sagging: E ka ntlafatsa bokhoni ba seretse se khahlanong le ho sisinyeha, haholo-holo kahong e otlolohileng, ho qoba tahlehelo ea thepa le ho netefatsa botenya bo sa fetoheng ba ho koahela.
3. Tšebeliso ea methylcellulose ka ho roala le ho khomarela
Methylcellulose e sebelisoa haholo ka ho roala le likhomaretsi e le motenya le stabilizer, e ka ntlafatsang haholo ts'ebetso ea lihlahisoa tsena.
Taolo e teteaneng le ea rheological: Ha ho etsoa litlolo, methylcellulose e ntlafatsa ho phalla ha eona le ho ata ha eona ka ho eketsa viscosity ea ho roala. Ho teteka ha ho roala ho ke ke ha thibela feela ho senya le ho phalla, empa hape ho etsa hore seaparo sa seaparo se be se tsitsitseng le se tsitsitseng, ho ntlafatsa phello ea kaho. Nakong ea ts'ebetso ea ho omisa ea ho roala, e boetse e phetha karolo ea ho thibela pula ea lisebelisoa le ho phunyeha ha ho roala.
Lintho tsa ho etsa lifilimi: Methylcellulose e ka fana ka thepa e ntle ea ho etsa filimi ea ho roala, e etsa hore seaparo se be thata le se sa senyeheng, 'me se be le metsi a itseng a hanyetsanang le boemo ba leholimo. E ka boela ea ntlafatsa sekhomaretsi sa pele le matla a tlamahano a sekhomaretsi.
4. Tšebeliso ea methylcellulose indastering ea lijo
Methylcellulose, e le tlatsetso ea lijo, e na le tšireletseho e ntle le botsitso 'me hangata e sebelisetsoa ho matlafatsa lijo, ho tsitsisa le ho emulsification. E ka ntlafatsa tatso, sebopeho le ponahalo ea lijo, ha e ntse e eketsa nako ea bophelo ba lijo.
Thickener le stabilizer: Lijong tse kang jelly, pudding, tranelate, sopho le soso, methylcellulose e ka sebetsa e le setenya ho etsa hore lijo li be le ponahalo le boreleli. E ka theha viscous colloid ka metsing, ea thibela stratification le pula ea metsoako ea lijo, 'me ea ntlafatsa botsitso ba sehlahisoa.
Moemeli oa mafura: Thermal gelation property ea methylcellulose e e fa tatso e kang ea mafura mochesong o tlaase, 'me e ka sebelisoa e le sebaka sa mafura lijong tse nang le lik'halori tse tlaase. E ka fokotsa mafura ntle le ho ama tatso, e thusa baetsi ba lijo ho hlahisa lihlahisoa tse phetseng hantle.
Ho boloka metsi: Lijong tse halikiloeng, methylcellulose e ka ntlafatsa matla a ho boloka metsi a hlama, e thibela ho phunyeha ho bakoang ke ho fetoha mouoane oa metsi, le ho ntlafatsa sebopeho le bonolo ba sehlahisoa.
5. Tšebeliso ea methylcellulose meriana le litlolo
Methylcellulose e sebelisoa haholo meriana le litlolo ka lebaka la ho se be chefo le ho lumellana ha eona hantle.
Kopo ho Meriana: Litokisetsong tsa meriana, methylcellulose e ka sebelisoa e le binder, filimi ea pele le e senyang matlapa ho etsa bonnete ba hore ho lokolloa le ho kenngoa ha lithethefatsi ka katleho. Meriana ea metsi, e ka sebelisoa e le ntho e emisang le e teteaneng ho thibela ho na ha lintho tse sebetsang.
Tšebeliso ho litlolo: Litlolong, methylcellulose e sebelisoa e le setepi le se tsitsitseng ho thusa lihlahisoa tse kang litlolo, litlolo, le li-shampoo ho boloka sebopeho se loketseng le botsitso. E ka thibela oli le metsi stratification le ho fana ka lihlahisoa lubrication le moisturizing liphello.
6. Kopo liindastering tse ling
Methylcellulose e boetse e phetha karolo ea bohlokoa liindastering tse ling. Ka mohlala, indastering ea ho etsa pampiri, methylcellulose e sebelisoa e le fiber dispersant ho ntlafatsa ho tšoana ha makhasi; indastering ea ceramic, e sebelisoa e le setlamo ho thusa ho kopanya phofo ea ceramic nakong ea ho bopa; indastering ea ho cheka oli, methylcellulose e sebelisoa e le seretse le setlolo bakeng sa ho cheka seretse ho ntlafatsa ts'ebetso ea ho cheka le botsitso.
Methylcellulose e ka bapala karolo ea bohlokoa masimong a mangata a indasteri ka sebopeho sa eona se ikhethang sa lik'hemik'hale le thepa ea 'mele. Botenya ba eona, ho boloka metsi, ho tsitsisa le ho etsa lifilimi ho etsa hore e be khetho e nepahetseng bakeng sa ho ntlafatsa libopeho tsa indasteri. Ebang ke thepa ea mohaho, liaparo, lijo, kapa meriana, litlolo le masimo a mang, methylcellulose e tlisitse lintlafatso tse kholo le ntlafatso ho lihlahisoa ka ts'ebetso ea eona e babatsehang. Nakong e tlang, ka tsoelo-pele e tsoelang pele ea theknoloji ea indasteri, menyetla ea ts'ebeliso ea methyl cellulose e tla ba e pharaletseng.
