Na methylcellulose ke ea maiketsetso kapa ea tlhaho?

Methylcelluloseke motsoako oa maiketsetso o tsoang ho cellulose, e leng polymer ea tlhaho e fumanoang maboteng a sele ea limela. Le hoja e tsoa mohloling oa tlhaho, mokhoa oa ho theha methylcellulose o kenyelletsa liphetoho tsa lik'hemik'hale, e leng se etsang hore e be ntho ea maiketsetso. Motsoako ona o sebelisoa hangata liindastering tse fapaneng ka lebaka la thepa ea oona e ikhethang le lits'ebetso tse feto-fetohang.

Cellulose, karolo ea mantlha ea mabota a sele ea limela, ke polysaccharide e nang le li-unit tsa glucose tse hokahaneng hammoho. E fana ka tšehetso ea sebopeho ho limela 'me ke e' ngoe ea metsoako e mengata ea lintho tse phelang Lefatšeng. Cellulose e ka ntšoa mehloling ea limela tse kang lehong, k'hothone, hemp le lisebelisoa tse ling tse nang le likhoele.

Ho hlahisa methylcellulose, cellulose e feta letotong la diketso tsa dikhemikhale. Tshebetso ena hangata e kenyeletsa ho phekola cellulose ka tharollo ya alkaline, e latelwe ke esterification ka methyl chloride kapa methyl sulfate. Diketso tsena di hlahisa dihlopha tsa methyl (-CH3) mokokotlong wa cellulose, e leng se fellang ka methylcellulose.

Ho eketsoa ha lihlopha tsa methyl ho fetola thepa ea 'mele le ea lik'hemik'hale ea cellulose, ho fana ka litšobotsi tse ncha motsoakong oa methylcellulose o hlahang. E 'ngoe ea liphetoho tse kholo ke ho eketseha ha ho qhibiliha ha metsi ha ho bapisoa le cellulose e sa fetoloang. Methylcellulose e bontša thepa e ikhethang ea rheological, e etsang litharollo tse hlabang ha li qhibiliha ka metsing. Boitšoaro bona bo etsa hore e be ea bohlokoa lits'ebetsong tse fapaneng tsa indasteri le tsa khoebo.

Methylcellulose e sebelisoa haholo indastering ea lijo e le setefatsi, se tsitsitseng le se kopanyang. E thusa ho rarahana le ho tsitsisa ha lihlahisoa tse ngata tsa lijo, ho kenyeletsoa lisoso, sopho, ice cream le lintho tse entsoeng ka bohobe. Ho feta moo, hangata e sebelisoa mefuteng ea meriana e le setlama tlhahisong ea matlapa le e le sesebelisoa sa ho fetola viscosity li-cream le li-ointments tse sebelisoang ka tlung.

Kahong le thepa ea kaho,methylcellulosee sebetsa e le motsoako oa bohlokoa ka har'a li-mortar tse omileng tse kopantsoeng, moo e sebetsang e le sesebelisoa sa ho boloka metsi le ho ntlafatsa ho sebetsa. Bokhoni ba eona ba ho etsa li-suspension tse tsitsitseng, tse ts'oanang bo e etsa hore e be ea bohlokoa likhomaretsing tsa tile tsa ceramic, plaster le lihlahisoa tse tiisang samente.

Methylcellulose e sebelisoa tlhahisong ea lihlahisoa tsa tlhokomelo ea botho tse kang li-shampoo, litlolo le litlolo. Matla a eona a ho etsa filimi le bokhoni ba ho etsa li-gel tse bonaletsang li etsa hore e lokele mekhoa e fapaneng.

Leha e entsoe ka cellulose, methylcellulose e ntse e boloka tse ling tsa litšobotsi tse sireletsang tikoloho tse amanang le selelekela sa eona sa tlhaho. E ka bola tlas'a maemo a itseng 'me e nkoa e sireletsehile bakeng sa tšebeliso lijong le meriana ha e etsoa ho latela maemo a taolo.

methylcelluloseke motsoako oa maiketsetso o tsoang ho cellulose, e leng polymer ea tlhaho e fumanoang limela. Ka phetoho ea lik'hemik'hale, cellulose e fetoloa methylcellulose, e nang le thepa e ikhethang e thusang liindastering tse fapaneng, ho kenyeletsoa lijo, meriana, kaho le tlhokomelo ea botho. Ho sa tsotellehe tšimoloho ea eona ea maiketsetso, methylcellulose e boloka litšobotsi tse ling tse mosa tikolohong 'me e amoheloa haholo ka lebaka la polokeho ea eona le ho tenyetseha ha eona.
