1. Hariho ubwoko bwinshi bwa hydroxypropyl methylcellulose HPMC, kandi ni irihe tandukaniro riri hagati yimikoreshereze yabo?
Igisubizo: Hydroxypropyl methylcellulose HPMC irashobora kugabanwa muburyo bwubwoko nubwoko bushushe. Ibicuruzwa byubwoko bukwirakwira vuba mumazi akonje bikabura mumazi. Muri iki gihe, amazi ntagira ubwiza, kubera ko HPMC ikwirakwizwa mu mazi gusa, nta gushonga nyabyo. Nyuma yiminota igera kuri 2, ubwiza bwamazi bwiyongereye buhoro buhoro, bikora colloid ibonerana. Ibicuruzwa bishushe, iyo uhuye namazi akonje, birashobora gukwirakwira vuba mumazi ashyushye bikabura mumazi ashyushye. Iyo ubushyuhe bugabanutse ku bushyuhe runaka, ubukonje bugaragara buhoro buhoro kugeza igihe habaye ibibyimba bisobanutse neza. Ubwoko bushyushye burashobora gukoreshwa gusa mubifu ya pome na minisiteri. Muri kole y'amazi no gusiga irangi, ibintu byo guhuzagurika bizabaho kandi ntibishobora gukoreshwa. Ubwoko bwakanya bufite intera yagutse ya porogaramu. Irashobora gukoreshwa mubifu ya poro na minisiteri, kimwe no mumavuta ya kole hamwe n irangi, nta kubuza.
2. Niyihe ntego nyamukuru ya hydroxypropyl methylcellulose (HPMC)?
Igisubizo: HPMC ikoreshwa cyane mubikoresho byubaka, gutwikira, ibisigazwa byubukorikori, ububumbyi, ubuvuzi, ibiryo, imyenda, ubuhinzi, kwisiga, itabi nizindi nganda. HPMC irashobora kugabanywamo: urwego rwubwubatsi, urwego rwibiryo hamwe nu rwego rwa farumasi ukurikije intego. Kugeza ubu, ibyinshi mubicuruzwa byo murugo ni urwego rwubwubatsi. Mu cyiciro cyubwubatsi, ingano yifu ya putty nini cyane, hafi 90% ikoreshwa mubifu ya putty, naho ibindi bikoreshwa mumasima ya sima na kole.
3. Ni ubuhe buryo bwo gushonga bwa hydroxypropyl methylcellulose HPMC?
Igisubizo: Uburyo bwo gushonga amazi ashyushye: Kubera ko HPMC idashonga mumazi ashyushye, HPMC irashobora gukwirakwizwa kimwe mumazi ashyushye mugihe cyambere, hanyuma igashonga vuba iyo ikonje. Uburyo bubiri busanzwe busobanurwa gutya:
1), ongeramo 1/3 cyangwa 2/3 by'amazi asabwa muri kontineri, hanyuma ubishyuhe kugeza kuri 70 ° C, ukurikije uburyo bwa 1), ukwirakwiza HPMC, utegure amazi ashyushye; hanyuma ongeramo amazi asigaye mumazi ashyushye Muri slurry, imvange yarakonje nyuma yo gukurura.
Uburyo bwo kuvanga ifu: Vanga ifu ya HPMC ninshi mubindi bintu byifu yifu, vanga neza na mixer, hanyuma ushyiremo amazi kugirango ushonga, hanyuma HPMC irashobora gushonga muriki gihe idakomatanye, kuko muri HPMC harimo bike gusa agace gato. Ifu izahita ishonga ihuye namazi. —— Ubu buryo bukoreshwa nifu ya putty nabakora minisiteri. [Hydroxypropyl methylcellulose (HPMC) ikoreshwa nkibintu byabyimbye kandi bigumana amazi muri minisiteri yifu.
2), shyira amazi asabwa muri kontineri, hanyuma ubishyuhe kugeza kuri 70 ℃. Hydroxypropyl methylcellulose yongeweho buhoro buhoro hamwe no gukurura buhoro, mu ikubitiro HPMC ireremba hejuru y’amazi, hanyuma buhoro buhoro ikora ibibyimba, bikonjeshwa no gukurura.
4. Nigute dushobora gusuzuma ubuziranenge bwa hydroxypropyl methylcellulose (HPMC) byoroshye kandi byihuse?
Igisubizo: (1) Imbaraga rukuruzi: nini nini nini, uburemere nibyiza. binini, mubisanzwe kubera
. Nyamara, ibyinshi mubicuruzwa byiza bifite umweru mwiza.
(3) Ubwiza: Ubwiza bwa HPMC muri rusange ni mesh 80 na mesh 100, naho mesh 120 ni mike. Hafi ya HPMC ikorerwa muri Hebei ni mesh 80. Nibyiza, nibyiza muri rusange.
. Iyo hejuru yohereza, nibyiza, byerekana ko hari ibintu bike bidashonga muri. Ubucucike bwa reaction ya vertical muri rusange nibyiza, kandi nibya reaction ya horizontal ni bibi, ariko ntidushobora kuvuga ko ubwiza bwa reaction ya vertical iruta iya reaction ya horizontal, kandi hariho ibintu byinshi byerekana ubwiza bwibicuruzwa. Hydroxypropyl ibiyirimo ni ndende, kandi hydroxypropyl irimo, amazi meza ni meza.
5. Ni ibihe bimenyetso nyamukuru bya tekinike ya hydroxypropyl methylcellulose (HPMC)?
Igisubizo: Hydroxypropyl ibirimo hamwe nubwiza, abakoresha benshi bita kuri ibi bipimo byombi. Iyo hydroxypropyl iri hejuru, niko gufata amazi neza. Viscous, gufata amazi, ugereranije (aho
6. Ni ubuhe buryo bukwiye bwa hydroxypropyl methylcellulose (HPMC)?
Igisubizo: Ifu yuzuye muri rusange ni 100.000 Yuan, kandi minisiteri irasaba cyane, kandi biroroshye gukoresha 150.000. Byongeye kandi, uruhare runini rwa HPMC ni ukugumana amazi, hagakurikiraho kubyimba. Mu ifu ya putty, mugihe cyose gufata amazi ari byiza kandi ubwiza buri hasi (70.000-80,000), birashoboka. Byumvikane ko, niba ibishishwa biri hejuru, kugereranya amazi ni byiza. Iyo ibishishwa birenga 100.000, ingaruka zo kwifata mu gufata amazi Ntabwo ari nyinshi. Byose) nabyo nibyiza, kandi viscosity ni ndende, kandi nibyiza gukoresha mumabuye ya sima.
7. Ni ibihe bikoresho by'ibanze bya hydroxypropyl methylcellulose (HPMC)?
Igisubizo: Ibikoresho nyamukuru bya hydroxypropyl methylcellulose (HPMC): ipamba itunganijwe, methyl chloride, okiside ya propylene, ibindi bikoresho fatizo birimo flake alkali, aside, toluene, isopropanol, nibindi.
