Gukoresha methyl selulose mubiryo

Cellulose ni polymer karemano cyane muri kamere. Ni umurongo wa polymer wuzuye uhujwe na D-glucose ukoresheje β- (1-4) glycosidic. Urwego rwa polymerisation ya selile rushobora kugera ku 18.000, naho uburemere bwa molekile bukagera kuri miliyoni nyinshi.

Cellulose irashobora kubyazwa umusaruro wibiti cyangwa ipamba, nayo ubwayo ntishobora gushonga mumazi, ariko ikomezwa na alkali, igashyirwa hamwe na methylene chloride na okiside ya propylene, ikogejwe namazi, hanyuma ikuma kugirango ibone amazi ya methyl selulose (MC) na hydroxypropyl methylcellulose (HPMC), ni ukuvuga mikorobe na hydroxypropoxy ikoreshwa mugusimbuza amatsinda ya hydroxyl kumyanya ya C2, C3 na C6 ya glucose kugirango ikore ethers ya selile.

Methyl selulose ni impumuro nziza, yera kugeza yuzuye ifu yera yera igaragara, kandi pH yumuti iri hagati ya 5-8.

Uburyo bwa metoxylile ya methylcellulose ikoreshwa nkinyongera yibiribwa mubusanzwe buri hagati ya 25% na 33%, urwego rujyanye no gusimburwa ni 17-2.2, naho urwego rwo hejuru rwo gusimbuza ruri hagati ya 0-3.

Nkongeweho ibiryo, vitamine ya hydroxypropyl methylcellulose ikunze kuba hagati ya 19% na 30%, naho hydroxypropoxyl ikunze kuba hagati ya 3% na 12%.

Ibiranga gutunganya

gel

Methylcellulose/ Hydroxypropylmethylcellulose ifite imiti igabanya ubukana.

Methyl selulose / hydroxypropyl methyl selulose igomba gushonga mumazi akonje cyangwa mumazi asanzwe. Iyo igisubizo cyamazi gishyushye, ubukonje buzakomeza kugabanuka, kandi gelation izabaho mugihe igeze kubushyuhe runaka. Muri iki gihe, methyl selulose / hydroxypropyl methyl selulose Igisubizo kiboneye cya propyl methylcellulose cyatangiye guhinduka amata yera y’amata yera, kandi ububobere bugaragara bwiyongereye vuba.

Ubu bushyuhe bwitwa ubushyuhe bwo gutangiza ubushyuhe bwa gel. Mugihe gel ikonje, ibigaragara bigaragara neza bigabanuka vuba. Ubwanyuma, umurongo wijimye iyo gukonjesha bihuye nubushuhe bwambere bwo gushyushya viscosity curve, gel ihinduka igisubizo, igisubizo gihinduka gel iyo gishyushye, kandi inzira yo gusubira mubisubizo nyuma yo gukonja irahinduka kandi igasubirwamo.

Hydroxypropyl methylcellulose ifite ubushyuhe bwinshi bwo gutangira ubushyuhe burenze methylcellulose n'imbaraga za gel nkeya.

Pimikorere

1. Ibikoresho byo gukora firime

Filime zakozwe na methylcellulose / hydroxypropylmethylcellulose cyangwa firime zirimo byombi birashobora gukumira neza kwimuka kwamavuta no gutakaza amazi, bityo bigatuma umutekano uhagaze neza.

2. Kwimura imitungo

Methylcellulose / Hydroxypropylmethylcellulose irashobora kugabanya ubukana bwubutaka no kugabanya ibinure byamavuta kugirango emulisiyo ihamye.

3. Kugenzura igihombo cyamazi

Methylcellulose / Hydroxypropylmethylcellulose irashobora kugenzura neza iyimuka ry’ibiribwa biva mu bukonje bikagera ku bushyuhe busanzwe, kandi birashobora kugabanya ibyangiritse, korohereza urubura hamwe n’imihindagurikire y’ibiribwa biterwa na firigo.

4. Imikorere ifatika

Methylcellulose / Hydroxypropylmethylcellulose ikoreshwa muburyo bugaragara kugirango iteze imbere imbaraga nziza zogukomeza mugukomeza kugenzura neza no kurekura uburyohe.

5. Gutinda gukora hydration

Gukoresha methylcellulose / hydroxypropylmethylcellulose birashobora kugabanya ububobere bwo kuvoma ibiryo mugihe cyo gutunganya amashyuza, bityo bikazamura neza umusaruro. Kugabanya ibyuka nibikoresho byangiza, byihutisha ibihe byinzira, bizamura imikorere yubushyuhe, kandi bigabanya gushinga amafaranga.

6. Gukora neza

Methylcellulose / Hydroxypropylmethylcellulose irashobora gukoreshwa ifatanije na krahisi kugirango itange ingaruka zifatika, zishobora kongera cyane ubukonje ndetse no kurwego rwo hasi cyane.

7. Igisubizo gihamye mugihe cya acide na alcool

Methylcellulose / Hydroxypropylmethylcellulose ibisubizo birahagaze kugeza kuri pH 3 kandi bifite umutekano muke mubisubizo birimo inzoga.

Gukoresha methyl selulose mubiryo

Methyl selulose ni ubwoko bwa selile ya ionic selile iterwa no gukoresha selile naturel nkibikoresho fatizo no gusimbuza amatsinda ya hydroxyl kumurongo wa anhidrous glucose muri selile hamwe nitsinda ryimikorere. Ifite kubika amazi, kubyimba, emulisile, gukora firime, guhuza n'imihindagurikire yagutse ya pH nibikorwa byubuso nibindi bikorwa.

Ikiranga umwihariko wacyo ni gelasiyo ihindagurika cyane, ni ukuvuga igisubizo cyayo cyamazi ikora gel iyo ishyushye, igasubira mubisubizo iyo ikonje. Ikoreshwa cyane mubiribwa bitetse, ibiryo bikaranze, desert, isosi, isupu, ibinyobwa, na essence. na bombo.

Geli ya super muri methyl selulose ifite imbaraga za gel inshuro zirenze eshatu iy'ubushyuhe bwa methyl selulose isanzwe, kandi ifite imiterere ikomeye ikomeye yo gufatira hamwe, gufata amazi no kubika imiterere.

Iremera ibiryo byahinduwe kugirango bigumane ibyifuzwa bifatika hamwe numunwa wumutobe haba mugihe ndetse no mugihe kinini nyuma yo gushyuha. Ubusanzwe porogaramu ni ibiryo bikonje byihuse, ibikomoka ku bimera, inyama zasubiwemo, amafi n’ibikomoka ku nyanja hamwe na sosiso zifite amavuta make.
