Ngaba i-methylcellulose yenziwe okanye yendalo?

I-methylcellulosei-synthetic compound ephuma kwi-cellulose, i-polymer yendalo efumaneka kwiindonga zeeseli zezityalo. Nangona ivela kumthombo wendalo, inkqubo yokudala i-methylcellulose ibandakanya ukuguqulwa kweekhemikhali, okwenza kube yinto yokwenziwa. Le khompawundi iqhele ukusetyenziswa kumashishini ahlukeneyo ngenxa yeempawu zayo ezizodwa kunye nezicelo eziguquguqukayo.

I-Cellulose, inxalenye ephambili yeendonga zeeseli zesityalo, yi-polysaccharide equka iiyunithi ze-glucose ezidityanisiweyo. Ibonelela ngenkxaso yesakhiwo kwizityalo kwaye yenye yezona zinto zininzi kakhulu kwi-organic compounds eMhlabeni. I-cellulose inokukhutshwa kwimithombo yezityalo ezifana neenkuni, umqhaphu, i-hemp, kunye nezinye izinto ze-fibrous.

Ukuvelisa i-methylcellulose, i-cellulose ifumana uchungechunge lwee-chemical reactions. Inkqubo ibandakanya ukunyanga i-cellulose ngesisombululo se-alkaline, elandelwa yi-esterification nge-methyl chloride okanye i-methyl sulfate. Ezi mpendulo zazisa amaqela e-methyl (-CH3) kwi-cellulose backbone, ekhokelela kwi-methylcellulose.

Ukongezwa kwamaqela e-methyl kuguqula iipropati ezibonakalayo kunye neekhemikhali zeselulosi, ukunika iimpawu ezintsha kwisiphumo se-methylcellulose compound. Olunye lolona tshintsho lubalulekileyo kukunyibilika kwamanzi xa kuthelekiswa neselulosi engalungiswanga. I-Methylcellulose ibonisa iimpawu ezikhethekileyo ze-rheological, zenza izisombululo ze-viscous xa zichithwa emanzini. Oku kuziphatha kwenza ukuba kuxabiseke kwizicelo ezahlukeneyo zeshishini kunye nezorhwebo.

I-Methylcellulose ifumana ukusetyenziswa okubanzi kwishishini lokutya njenge-thickener, stabilizer, kunye ne-emulsifier. Inegalelo kukwakheka nokungaguquguquki kwezinto ezininzi zokutya, kuquka iisosi, iisuphu, iiayisi khrim, kunye nezinto zokubhaka. Ukongeza, iqhele ukusetyenzwa kuqulunqo lwamayeza njengesibophelelo kwimveliso yethebhulethi kwaye njengesilungisi se-viscosity kwiikhrimu ze-topical kunye namafutha.

Kwizinto zokwakha nezokwakha,i-methylcelluloseisebenza njengesithako esiphambili kumxube owomileyo womxube, apho usebenza njenge-arhente yokugcina amanzi kunye nokuphucula ukusebenza. Ukukwazi kwayo ukwenza ukumiswa okuzinzileyo, okufanayo kuyenza ixabiseke kwi-ceramic tile adhesives, i-plaster, kunye neemveliso zesamente.

I-methylcellulose isetyenziselwa ukuveliswa kweemveliso zokhathalelo lomntu ezifana neshampu, iilotion, kunye nezinto zokuthambisa. Iimpawu zayo zokwenza ifilimu kunye nokukwazi ukudala iigels ezicacileyo zenza ukuba zilungele ukuqulunqwa okuhlukeneyo.

Ngaphandle kokuba yenziwe kwi-cellulose, i-methylcellulose igcina ezinye zeempawu ezihambelana nokusingqongileyo ezinxulumene ne-precursor yayo yendalo. I-biodegradable phantsi kweemeko ezithile kwaye ithathwa njengekhuselekile ukusetyenziswa ekutyeni nakwi-pharmaceutical applications xa yenziwe ngokwemigangatho yolawulo.

i-methylcelluloseyikhompawundi yokwenziwa evela kwi-cellulose, i-polymer yendalo efumaneka kwizityalo. Ngokuguqulwa kweekhemikhali, i-cellulose iguqulwa ibe yi-methylcellulose, ebonisa iipropati ezikhethekileyo eziluncedo kumashishini amaninzi, kuquka ukutya, amayeza, ukwakhiwa kunye nokunyamekela komntu. Nangona imvelaphi yayo yokwenziwa, i-methylcellulose igcina iimpawu ezithile eco-friendly kwaye yamkelwa ngokubanzi ngenxa yokhuseleko nokusetyenziswa kwezinto ezininzi.
