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-ifu, impumuro nziza kandi itaryoshye.

2. Ingano ya Particle: igipimo cyatsinze mesh 100 kirenze 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 bwubuso: 20% igisubizo cyamazi ni 42-56dyn / cm.

7. 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.

9.

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. Ifu yumye ivanze irimo selile ether irashobora 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 kugabanya kugabanuka no kurwanya imbaraga za minisiteri hamwe nudupapuro twuzuza.

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

7. Irashobora kongera imbaraga zo guhagarara 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 bwinshi, muri rusange inkoni 100.000 kugeza 150.000, bituma putty ifata neza kurukuta.

3. Kunoza kugabanuka kugabanuka no guhangana, kunoza ubwiza bwubuso.

Igipimo cyerekana: 0.3 ~ 0.4% kurukuta rwimbere; 0.4 ~ 0.5% kurukuta rwinyuma;

Urukuta rwo hanze

1. Kongera imbaraga zifatika hejuru yurukuta, no kongera amazi, kugirango imbaraga za minisiteri zishobore kunozwa.

2. Kunoza amavuta na plastike kugirango utezimbere ubwubatsi. Irashobora gukoreshwa hamwe na Shenglu marike ya krahisi ether kugirango ishimangire minisiteri, yoroshye kubaka, igatwara igihe kandi igateza imbere-gukora neza.

3. Kugenzura iyinjira ryumwuka, bityo ukureho uduce duto duto twa coating hanyuma ugire ubuso bwiza.

Gypsumu yamashanyarazi nibicuruzwa bya plaster

1. Gutyo, kunoza imikorere.

2. Kubika amazi menshi, kongera igihe cyakazi cya minisiteri, no gutanga ingufu za mashini iyo zikomeye.

3. Mugucunga uburinganire bwa minisiteri kugirango habeho igipimo cyiza cyo hejuru.

Isima ishingiye kuri sima na minisiteri yububiko

1.

2. Kubika amazi menshi, kongera igihe cyakazi cya minisiteri, kunoza imikorere, no gufasha minisiteri gukora imbaraga za mashini mugihe cyagenwe.

3. Hamwe no kubika amazi yihariye, birakwiriye cyane kubumba amatafari yo kwinjiza amazi menshi.

Umwanya wuzuye wuzuza

1. Kubika amazi meza, bishobora kongera igihe cyo gukonja no kunoza imikorere. Amavuta menshi atuma kubaka byoroha kandi byoroshye.

2. Kunoza kugabanuka kugabanuka no guhangana, kunoza ubwiza bwubuso.

3. Tanga uburyo bworoshye kandi bumwe, kandi utume ubuso buhuza bukomera.

Amatafari

1. Kora ibintu byumye bivanze byoroshye kuvanga nta kubyimba, bityo uzigame igihe cyakazi. Kandi utume ubwubatsi bwihuta kandi bunoze, bushobora kunoza imikorere no kugabanya ibiciro.

2. Mu kongera igihe cyo gukonjesha, imikorere ya tiling iratera imbere.

3. Tanga ingaruka nziza zifatika, hamwe na skid irwanya cyane.

kwigereranya ibikoresho byo hasi

1. Tanga ibishishwa kandi birashobora gukoreshwa nkimfashanyo yo kurwanya imyanda.

2. Kongera amazi no kuvomerera, bityo bikazamura imikorere yo gutunganya ubutaka.

3. Kugenzura gufata amazi, bityo bikagabanya cyane gucika no kugabanuka.

Amazi ashingiye kumazi no gukuraho amarangi

1. Kongera igihe cyubuzima bwo kubuza ibimera gutura. Guhuza neza nibindi bice hamwe nibinyabuzima bihamye.

2. Irashonga vuba idafite ibibyimba, ifasha koroshya inzira yo kuvanga.

3. Gutanga amazi meza, harimo kumeneka hasi no kuringaniza neza, bishobora gutuma ubuso bwiza burangira kandi bikarinda irangi rihagaze.

4.

Ikibaho cya beto

1. Kongera ubushobozi bwibicuruzwa biva hanze, hamwe nimbaraga nyinshi zo guhuza hamwe namavuta.

2. Kunoza imbaraga zitose hamwe no gufatisha urupapuro nyuma yo gukuramo.
