Ingabe i-methyl cellulose i-cellulose ether?

Isingeniso ku-Cellulose Teshers:
I-cellulose ingenye yezindlela eziningi eziningi ze-organic emhlabeni, ezitholakala ezindongeni zeseli zezitshalo. Kuyinto e-polysaccharide ehlanganiswe ukuphinda ama-glucose amayunithi axhumeke ndawonye ngu-β (1 → 4) amabhondi e-glycosidic. I-Cellulose Afers iyinzuzo ye-cellulose, lapho i-hydroxyls yamaqembu athile noma ngaphezulu (-OH) ifakwe esikhundleni ngamaqembu ether (-OM). Lokhu kufakazelwa okuguqula izakhiwo zomzimba nezamakhemikhali ze-cellulose, okwenza kube lula ukuthola izinhlelo ezahlukahlukene zezimboni.

Methyl cellulose: incazelo nesakhiwo:
I-Methyl celtuleose iyi-cellulose ether etholakala ku-cellulose ngokusebenzisa ukufaka amaqembu ama-hydroxyl nge-methdyl (-ch3) amaqembu ether. Lokhu kufakazelwa kwemiphumela ku-polymer nge-solubity ethuthukisiwe emanzini namanye ama-sol sol solsose aqhathaniswa ne-cellulose yendabuko. Izinga lokufaka esikhundleni (DS) lisho inani elijwayelekile lamaqembu e-hydroxyl athathelwe indawo amaqembu we-methyl ether ngeyunithi ye-glucose ku-cellulose chain futhi anqume izakhiwo ze-methyl cellulose.

Isakhiwo samakhemikhali se-methyl cellulose singahluka ngokuya ngezinga lokufakwa esikhundleni kanye nokusatshalaliswa kwamaqembu we-methyl ether ngase-cellulose. Ngokuvamile, ama-methylll cellulose molecule angama-polymers aqondile anamaketanga aguqukayo, avumele ukuba akha izixazululo ngezakhiwo eziyingqayizivele zembobo.

Inqubo Yokukhiqiza:
I-methyl cellulose ikhiqizwa ngokujwayelekile ngokusabela kokusheshisa kwe-cellulose nge-methyl chloride noma i-methyl sulfate phambi kwama-alkaline catalysts. Ukuphendula kubandakanya ukufaka esikhundleni samaqembu ama-hydroxyl namaqembu we-methyl ether, okuholela ekwakhekeni kwe-methyl cellulose. Izinga lokufaka esikhundleni semali lingalawulwa ngokulungisa izimo zokuphendula ezifana nokushisa, isikhathi sokuphendula, kanye nesilinganiso se-cellulose ku-methylating ejenti.

Ngemuva kwe-synthesis, umkhiqizo uhlukanisa izinyathelo zokuhlanzwa ukuze ususe ukungcola kanye nemikhiqizo. Lokhu kungafaka ukugeza, ukuthokozisa, kanye nokomisa izinqubo ukuthola i-methyl cellulose powllose noma ama-granule.

Izakhiwo ze-methyl cellulose:
I-methyl cellulose ibonisa izakhiwo ezimbalwa ezihlukile ezenza zilungele izinhlelo eziningi zokusebenzisa:

I-Solubity yamanzi: I-methyl cellulose iyanyibilika emanzini abandayo, yakha izixazululo ezicacile, ezibonakalayo. I-solubity ingathuthukiswa futhi ngokwandisa izinga lokufaka esikhundleni.

Ukuqina okushisayo: I-Methyl cellulose iqinile, igcina izakhiwo zayo ngobubanzi bokushisa. Le mpahla yenza ukuthi ilungele izinhlelo zokusebenza ezidinga ukumelana nokushisa.

Ukwakheka kwamafilimu: I-methyl cellulose ingakha amafilimu aguqukayo, amafilimu asobala lapho aphonswa kwisixazululo. Lawa mafilimu anezakhiwo ezinhle zokuvimba futhi athole izicelo ezitsheni nasezintweni ezifakwayo.

Ukuqina kanye noGalelling: I-methyl celtulose isebenza njenge-ejenti yokuqina ezixazululweni zamanzi, ukukhulisa ukubonana nokuthuthukisa ukuthungwa. Ingakha futhi ama-gels aguqukayo ashelelayo ekugxilweni okuphezulu, okuwusizo ekudleni kokudla kanye nokwenziwa kwemithi.

Umsebenzi ongaphezulu

Izicelo ze-methyl cellulose:
I-methyl celtulose ithola izinhlelo ezisakazekile ezinhlotsheni ezahlukahlukene ngenxa yezindawo zayo eziguquguqukayo:

Imboni yokudla: Embonini yokudla, i-methyl cellulose isetshenziswa njenge-ejenti yokuqina, i-Stabilizer, ne-emulsifier emikhiqizweni efana nososo, ukugqoka, ama-dessert, nezinto zokubhaka nezinto zokubhaka. Kuthuthukisa ukuthungwa, kuthuthukisa umlomo, futhi kunikeze ukuqina okuxakile.

IMITHETHO: I-methyl cellulose isetshenziswa kabanzi ekwakhiweni kwemithi njenge-binder, ukuqhekeka, ne-ejenti yokukhishwa okuqhubekayo kumathebulethi kanye nama-caplule. Ingasetshenziswa futhi ekwakhiweni kwe-topical okufana nama-gels, okhilimu, kanye namafutha okugcoba kwawo kanye nezakhiwo ze-mucoadhesive.

Ukwakhiwa: I-methyl cellulose isetshenziswa ezintweni zokwakha ezifana nodaka, udaka, kanye namathayela anamathela njenge-ejenti yokuqina kanye nokugcinwa kwamanzi. Kuthuthukisa ukusebenziseka, ukunamathela, nokuvimbela ukugcwala kwezingxube ezimanzi.

Izimonyo: Ezimonyo kanye nemikhiqizo yokunakekelwa komuntu siqu, i-methyl cellulose isetshenziswa ekwakhiweni okufana nokhilimu, ama-lotion, ama-shampoos kanye namazinyo njengomuntu omkhulu, i-stabilizer kanye ne-ejenti eyakha ifilimu. Inikeza ukulawulwa kwe-viscosity, kuthuthukisa ukuthungwa, futhi kuthuthukise ukusebenza komkhiqizo.

Izicelo zezimboni: I-Methyl Cellulose iqashwa kwizicelo ezahlukahlukene zezimboni ezinjengokuphrinta kwendwangu, ukumboza amaphepha, kanye nokwakhiwa kwamaphethini ngokuqina kwayo, okubophayo kanye nezakhiwo ezenziwe ngefilimu.

Umthelela Wezemvelo:
Ngenkathi i-methyl cellulose icatshangelwa ngokuvamile ukuze isetshenziswe ekudleni, emikhakheni, kanye nezinye izinhlelo zokusebenza, umthelela wayo wezemvelo kufanele ubhekwe ngokucophelela. I-Cellulose Tashers iyi-vioderhradable polymers etholakala kwizinsizakusebenza ezivuselelekayo, ibenze banobungane bemvelo ngokuqhathaniswa nama-polymers okwenziwa. Kodwa-ke, inqubo yokukhiqiza ingahle ifake ukusetshenziswa kwamakhemikhali namandla, kufaka isandla ekungcoleni kwemvelo kanye nokuphuma kwegesi abamba ukushisa.

Kwenziwa imizamo yokuthuthukisa ukuqina kokukhiqizwa kwe-cellulose ether ngokusetshenziswa kwemizila eluhlaza okotshani, imithombo yamandla evuselelekayo, nokuphinda usebenzise kabusha ngemikhiqizo. Ngokwengeziwe, ukulahlwa kwemikhiqizo equkethe ama-methyllulose-aqukethe izinto kufanele kulawulwe ngokuzibophezela ukunciphisa ukungcoliswa kwemvelo.

I-methyl celtulose iyi-cellulose ether enezakhiwo ezihlukile ezenza zibalulekile kuzo zonke izimboni ezahlukahlukene. I-solubility yayo yamanzi, ukuqina okushisayo, ukuqina, kanye nezakhiwo ezenziwe ngefilimu zikulungele ukusetshenziswa kwezicelo ezahlukahlukene, kubandakanya nokudla, amakhambi, izimonyo kanye nokwakha. Ngenkathi i-methyl celtule Sekukonke, i-methyl celtulose idlala indima ebalulekile kubuchwepheshe besimanje kanye nempilo yansuku zonke, okufaka isandla ekuthuthukisweni kwemikhiqizo nezixazululo ezintsha.
