Ikoreshwa ryinshi rya Hydroxypropyl Methyl Cellulose

Hydroxypropyl methyl selulose, yitwa (HPMC): hydroxypropyl methyl selulose (HPMC) ni ifu yera itagira impumuro nziza, itaryoshye, idafite uburozi, hariho ubwoko bubiri bwihuse kandi butahita, ako kanya, Iyo buhuye namazi akonje, bwihuse ikwirakwira ikabura mu mazi.Muri iki gihe, amazi ntagira ubwiza.Nyuma yiminota igera kuri 2, ubwiza bwamazi bwiyongera, bugakora colloid ibonerana.Ubwoko butari ako kanya: Irashobora gukoreshwa gusa mubicuruzwa byifu byumye nka puderi ya pome na sima ya sima.Ntishobora gukoreshwa mumazi ya kole no gusiga irangi, kandi hazabaho guhuzagurika.

A. Imiterere yumubiri nubumara

1. Kugaragara: Ifu yera cyangwa yera-yera, impumuro nziza kandi itaryoshye.

2. Ingano y'ibice: igipimo cya pass ya 100 mesh irenze 98.5%;igipimo cya pass ya 80 mesh irenze 100%.

3. Ubushyuhe bwa Carbone: 280-300 ° C.

4. Ubucucike bugaragara: 0.25-0.70g / (mubisanzwe hafi 0.5g /), uburemere bwihariye 1.26-1.31.

5. Ubushyuhe bwo guhindura ibara: 190-200 ° C.

6. Ubushyuhe bwo hejuru: 20% igisubizo cyamazi ni 42-56dyn / cm.

7. Gukemura: Gushonga mumazi hamwe na solge zimwe na zimwe, nka Ethanol / amazi, propanol / amazi, dichloroethane, nibindi muburyo bukwiye.Igisubizo cyamazi gifite ibikorwa byubuso, gukorera mu mucyo no gukora neza.Ibicuruzwa bifite ibisobanuro bitandukanye bifite ubushyuhe butandukanye bwa gelation, aribwo mutungo wa HPMC.Gukemura biratandukanye nubwiza, uko ubukonje bugenda bugabanuka, niko bigenda byiyongera, ibisobanuro bitandukanye bya HPMC bifite itandukaniro mubikorwa, kandi iseswa rya HPMC mumazi ntabwo bigira ingaruka kubiciro bya pH.

8. Hamwe no kugabanuka kwibirimo, imikorere ya gel ya HPMC iriyongera, amazi yo kugabanuka aragabanuka, kandi ibikorwa byo hejuru nabyo biragabanuka.

Hydroxypropyl methylcellulose imikorere:

• Irashobora kubyimba minisiteri ivanze vuba kuburyo ifite ubwiza butose kandi ikarinda gutandukana.(kubyimba)

• Kubika amazi nacyo kiranga ikintu cyingenzi kiranga, gifasha kugumana ubwinshi bwamazi yubusa muri minisiteri, kugirango ibikoresho bya simaitike bigire igihe kinini cyo kuvoma nyuma yo gukoreshwa.(kubika amazi)

• Ifite ibintu byinjira mu kirere, bishobora kwinjiza umwuka mwiza kandi mwiza wo kunoza imikorere ya minisiteri.

B. Ibyiza bya hydroxypropyl methylcellulose mubijyanye nibikoresho byubaka

imikorere:

1. Biroroshye kuvanga na formula yumye.

2. Ifite ibiranga gukwirakwiza amazi akonje.

3. Hagarika ibice bikomeye, bigatuma imvange yoroshye kandi imwe.

kuvanga:

1. Amata yumye arimo selulose ether arashobora kuvangwa byoroshye namazi.

2. Wihutire kubona ibyifuzo byifuzwa.

3. Iseswa rya selile ether irihuta kandi idafite ibibyimba.

kubaka:

1. Kunoza amavuta na plastike kugirango wongere imashini kandi wubake ibicuruzwa byoroshye kandi byihuse.

2. Kongera ibiranga gufata amazi no kongera igihe cyakazi.

3. Ifasha gukumira urujya n'uruza rwa minisiteri, minisiteri na tile.Ongera igihe cyo gukonjesha no kunoza imikorere.

4. Kunoza imbaraga zo guhuza amatafari.

5. Kongera imbaraga zo kurwanya kugabanuka no kurwanya imbaraga za minisiteri hamwe nu kibaho cyuzuza.

6. Kunoza ikirere kiri muri minisiteri, kugabanya cyane amahirwe yo guturika.

7. Irashobora kongera imbaraga zo guhagarikwa kwamazi ya tile.

8. Koresha hamwe na Max starch ether, ingaruka nibyiza!

C. Gukoresha hydroxypropyl methylcellulose mumwanya wubwubatsi

Amazi adashobora kwihanganira inkuta zimbere ninyuma:

1. Kubika amazi meza, bishobora kongera igihe cyo kubaka no kunoza imikorere.Amavuta menshi atuma kubaka byoroha kandi byoroshye.Itanga amande meza ndetse nuburyo bwimiterere yoroheje.

2. Ubukonje bukabije, muri rusange inkoni 100.000 kugeza 150.000, bituma putty ifata neza kurukuta.
