Ingabe i-methylcellulose yokwenziwa noma yemvelo?

I-methylcelluloseiyinhlanganisela yokwenziwa etholakala ku-cellulose, i-polymer yemvelo etholakala ezindongeni zamangqamuzana ezitshalo. Nakuba ivela emthonjeni wemvelo, inqubo yokudala i-methylcellulose ihilela ukuguqulwa kwamakhemikhali, okwenza kube into yokwenziwa. Le nhlanganisela isetshenziswa kakhulu ezimbonini ezahlukahlukene ngenxa yezakhiwo zayo ezihlukile kanye nezicelo eziguquguqukayo.

I-Cellulose, ingxenye eyinhloko yezindonga zamangqamuzana ezitshalo, iyi-polysaccharide ehlanganisa amayunithi e-glucose ahlanganiswe ndawonye. Inikeza ukusekelwa kwesakhiwo ezitshalweni futhi ingenye yezinto eziphilayo ezitholakala ngobuningi eMhlabeni. I-Cellulose ingakhishwa emithonjeni yezitshalo njengokhuni, ukotini, i-hemp, nezinye izinto ze-fibrous.

Ukukhiqiza i-methylcellulose, i-cellulose ibhekana nochungechunge lokusabela kwamakhemikhali. Inqubo ngokuvamile ihilela ukwelapha i-cellulose ngesisombululo se-alkaline, okulandelwa i-esterification nge-methyl chloride noma i-methyl sulfate. Lokhu kusabela kwethula amaqembu e-methyl (-CH3) kumgogodla we-cellulose, okuholela ku-methylcellulose.

Ukwengezwa kwamaqembu e-methyl kushintsha izakhiwo ezingokomzimba nezamakhemikhali ze-cellulose, kunikeza izici ezintsha kunhlanganisela ye-methylcellulose ewumphumela. Olunye lwezinguquko eziphawulekayo ukwanda kokuncibilika kwamanzi uma kuqhathaniswa ne-cellulose engashintshiwe. I-Methylcellulose ibonisa izakhiwo eziyingqayizivele ze-rheological, zakha izixazululo ze-viscous lapho zichithwa emanzini. Lokhu kuziphatha kukwenza kube wusizo ezinhlelweni ezahlukene zezimboni nezohwebo.

I-Methylcellulose ithola ukusetshenziswa okubanzi embonini yokudla njenge-thickener, stabilizer, kanye ne-emulsifier. Inomthelela ekwakhiweni nasekufaneni kwemikhiqizo eminingi yokudla, okuhlanganisa amasoso, amasobho, ama-ayisikhilimu, nezinto zokubhaka. Ukwengeza, ivamise ukusetshenziswa ekwenziweni kwemithi njengesihlanganisi ekukhiqizweni kwamathebulethi nanjengesishintshi se-viscosity kokhilimu besihloko namafutha okugcoba.

Ezokwakha kanye nezinto zokwakha,i-methylcelluloseisebenza njengesithako esiyisihluthulelo osikeni bengxube eyomile, lapho isebenza khona njenge-ejenti yokugcina amanzi futhi ithuthukisa ukusebenza. Ikhono layo lokwenza ukumiswa okuzinzile, okufanayo kuyenza ibe wusizo ezintweni ezinamathelayo zamathayela e-ceramic, ukhonkolo, nemikhiqizo kasimende.

I-methylcellulose isetshenziswa ekukhiqizeni imikhiqizo yokunakekelwa komuntu siqu njengama-shampoos, ama-lotions, nezimonyo. Izakhiwo zayo zokwenza ifilimu kanye nekhono lokudala amajeli asobala ayenza ifanele ukwakheka okuhlukahlukene.

Naphezu kokwenziwa ku-cellulose, i-methylcellulose igcina ezinye izici ezihambisana nemvelo ezihlobene nesandulela sayo semvelo. Iyakwazi ukubola ngaphansi kwezimo ezithile futhi ibhekwa njengephephile ukuze isetshenziswe ekudleni nasezinhlelweni zemithi lapho kukhiqizwa ngokuvumelana nezindinganiso zokulawula.

i-methylcelluloseiyinhlanganisela yokwenziwa etholakala ku-cellulose, i-polymer yemvelo etholakala ezitshalweni. Ngokuguqulwa kwamakhemikhali, i-cellulose iguqulwa ibe i-methylcellulose, ebonisa izakhiwo eziyingqayizivele eziwusizo ezinhlobonhlobo zezimboni, kuhlanganise nokudla, imithi, ukwakhiwa, nokunakekelwa komuntu siqu. Naphezu komsuka wayo wokwenziwa, i-methylcellulose ilondoloza ezinye izimfanelo ezivumelana nemvelo futhi yamukelwa kabanzi ngenxa yokuphepha nokuhlukahluka kwayo.
