Nibihe bibazo bisanzwe bya hydroxypropyl methylcellse?

1. Ni ubuhe buryo bukoreshwa na hydroxyproppopyl methylcellse (HPMC)?

HydroxyPropyl Methycellsellse yakoreshejwe cyane mu bikoresho by'ubwubatsi, ibisohokaga, ubuvuzi, ubuvuzi, ibiryo, kwisiga, itabi n'izindi ngamba. HydroxyPropyl Methylcellse irashobora kugabanywamo urwego rwubwubatsi, amanota yibiribwa hamwe nicyiciro cya farumasi ukurikije ibyifuzo byayo. Kugeza ubu, ibyinshi mu bicuruzwa byo mu rugo ni urwego rwo kubaka. Mu rwego rwo kubaka, ifu ya Prowty ikoreshwa mu mubare munini, hafi 90% ikoreshwa kuri Prowder ifu, kandi ahasigaye hakoreshwa kuri sima na kole.

2. Hariho ubwoko bwinshi bwa hydroxypropyl methylcellse (HPMC), kandi ni irihe tandukaniro rifite?

HPMC irashobora kugabanywamo ubwoko bwa ako kanya nuburyo bushyushye. Ibicuruzwa byubwoko ako kanya ukwirakwiza vuba mugihe bahuye namazi akonje kandi bazimira mumazi. Muri iki gihe, amazi adafite ubuyobe kuko HPMC yatatanye gusa mumazi gusa nta guseswa nyabyo. Nyuma yiminota 2, visosity yamahoro yiyongera buhoro buhoro, gukora virusi iboneye. Ibicuruzwa bishyushye, iyo byujuje amazi akonje, birashobora gutatana vuba mumazi ashyushye kandi ukabura mumazi ashyushye. Iyo ubushyuhe bugabanutse ku bushyuhe runaka, viscosity igaragara buhoro kugeza igihe ikora virusi iterana. Ubwoko bushyushye buke burashobora gukoreshwa gusa muri pattle ifu na minisiteri. Mu mazi no gusiga irangi, hazabaho ibintu byinjizamo ibintu kandi ntibishobora gukoreshwa. Ubwoko bwihuse bufite uburyo bwagutse bwa porogaramu. Irashobora gukoreshwa mubukonje na minisiteri, kimwe na kole yamazi kandi irangi, nta binyuranye.

3. Ni ubuhe buryo bwo kuvugurura bwa hydroxypropyl methylcellse (HPMC)?

Uburyo bushyushye bwamazi: Kubera ko HPMC idashonga mumazi ashyushye, HPMC irashobora gutatana rimwe mumazi ashyushye mugihe cyambere, hanyuma ahita ashonga vuba iyo akonje. Uburyo bubiri busanzwe busobanurwa kuburyo bukurikira:

1) Shira umubare ukenewe wamazi ashyushye muri kontineri no gushyuha kugeza kuri 70 ° C. HydroxyPropyl Methycellse yongeyeho buhoro buhoro itinda cyane, mu ntangiriro hpmc yareremba hejuru y'amazi, hanyuma igacekwa buhoro buhoro ihagarikwa.

2) Ongeraho 1/3 cyangwa 2/3 by'amazi asabwa muri kontineri, kandi uhambire kugeza kuri 70 ° C, ukurikije uburyo bwa 1), gutatanya hpmc kugirango utegure amazi ashyushye; Noneho ongeramo umubare usigaye wamazi akonje kumazi ashyushye, imvange yarakonje nyuma yo gukangura.

Uburyo bwo kuvanga powder: Kuvanga ifu ya HPMC hamwe nizindi mboro yifu, ivange neza hamwe na inval, hanyuma wongereho amazi yo gushonga, kuko hariho HPMC ntoya ishonga, kuko hari HPMC ntoya ifumbire, mugihe cyo guhura namazi. - Ifu ya fatride hamwe nababikora bakoresha ubu buryo. .

4. Nigute nakura ireme rya hydroxyproppopyl methylcellse (HPMC) byoroshye kandi byimazeyo?

. Ariko, ibicuruzwa byinshi byiza bifite channene nziza.

. Impeta nziza, muri rusange ivuga, ibyiza.

. Isumbabyose ikomatanya, ibyiza, byerekana ko hari amakosa make muri yo. Urungano rwabakira ruhagaritse muri rusange ni rwiza, kandi ubw'abakira batambitse muri horizontal, ariko ntibisobanura ko ubwiza bwabakiriye bukabije buruta abakira bitambitse, kandi ubuziranenge bwibicuruzwa bugenwa nibintu byinshi.

(4) Imbaraga zihariye: nini nini nini, nziza cyane. Umwihariko ni kinini, muri rusange kubera ko ibikubiye mu itsinda rya hydroxyPropyle ari hejuru, kandi ibikubiye mu itsinda rya hydroxyPropyl ni ndende, ihohoterwa ry'amazi rimeze neza.

5. Ni ubuhe buryo bwa hydroxypropyl methylcellse (HPMC) mu ifu ya Putty?

Umubare wa HPMC ukoreshwa mubikorwa bifatika biratandukanye bitewe nikirere, ubushyuhe, ubuziranenge bwa Calcium yibanze, formula yifu ya protyite na "ubuziranenge busabwa nabakiriya". Muri rusange, hagati ya kg 4 na 5 kg. Kurugero: Byinshi muri powder ifu muri Beijing ni 5 kg; Ibyinshi muri powder iko muri Guizhou ni 5 kg mu cyi na 4,5 kg mu gihe cy'itumba; Ingano ya Prowder i Yunnan ni ntoya, muri rusange 3 kg kugeza 4 kg, nibindi

6. Ni ubuhe buryo bukwiye bwa hydroxyproppopyl methylcellse (HPMC)?

Prowder ifu ihagije kuri Yuan 100.000, kandi ibisabwa kuri minisiteri biri hejuru, kandi 150.000 Yuan irasabwa kugirango ikoreshwe byoroshye. Byongeye kandi, imikorere yingenzi ya HPMC ni ifungwa ry'amazi, ikurikirwa no kubyimba. Muri ifu ya Putty, igihe cyose ihohoterwa rishingiye ku mazi ari ryiza kandi ko bigaragara ko ari hasi (70.000-80.000), birashoboka. Birumvikana ko hejuru cyane viscosiya, gusubizwa amazi meza. Iyo visosity irenze 100.000, urubyiruko ruzagira ingaruka ku kugumana amazi. Ntabwo akiri byinshi.

7. Nibihe bipimo nyamukuru bya tekiniki bya HydroxyPropyl Methylcellse (HPMC)?

HydroxyPropyl Ibirimo no mu rubyiruko, abakoresha benshi bahangayikishijwe n'ibi bipimo byombi. Abafite hydroxyroproppopyl muri rusange bafite isuku myiza. Umwe ufite ubushyuhe bwinshi afite igumana ryamazi, ugereranije (ntabwo rwose), kandi Umwe ufite ubutwari bwo hejuru akoreshwa neza muri sima.

8. Nibihe bikoresho nyamukuru bya hydroxyproppopyl methylcellse (HPMC)?

Ibikoresho nyamukuru bya hydroxypropyl methylcellse (HPMC): Ipamba yatunganijwe, umuswa wa methic, aside, aside, aside, Isopropanol, nibindi

9. Niyihe mikorere nyamukuru yo gusaba HPMC mubutaka bwa Putty, kandi bibaho byakozwe na shimi?

Muri Prowder ifu, HPMC igira uruhare rutatu yo kubyimba, kugumana amazi no kubaka. Kwinginga: Ubugari burashobora kwiyongera guhagarika no gukomeza umwambaro hejuru no hasi, no kurwanya kunyeganyega. Ihagarikwa ry'amazi: Kora ifu ya LIPTY yumye buhoro, kandi ifashe akajagari iz kwitwara munsi y'ibikorwa by'amazi. Kubaka: Ubugari bufite ingaruka zo gusiga, ishobora gutuma ifu ya LETY igira kubaka neza. HPMC ntabwo yitabira imiti iyo ari yo yose, ahubwo igira uruhare runini gusa. Ongeraho amazi kuri powder ifu hanyuma uyishyire kurukuta ni reaction yimiti, kuko ibintu bishya byashizweho. Niba ukuye ifu ya putty kurukuta kuva kurukuta, uyitoke mu ifu, kandi urongera ukoreshe, ntabwo bizakora kuko ibintu bishya (na calcium) byashizweho.). Ibice byingenzi bya Ifu ya Ash Calcium ni: imvange ya CA (OH) 2, Calcium Carbo3 yakozwe, mugihe HPMC yaguye gusa, mugihe cya HPMC gusa, ifasha amazi meza Calcium, kandi ntabwo yitabira reaction yose ubwayo.

10. HPMC ni selile itari ionic ether, none itari iconic niyihe?

Mu masezerano ya Layman, ntabwo ari ions ni ibintu bidakora ionize mumazi. Ionation ivuga inzira aho hatangwamo amashanyarazi yitandukanije na ™ iyoni ishobora kugenda muburyo bwihariye (nk'amazi, inzoga). Kurugero, sodium chloride (nacl), umunyu turya burimunsi, turasenyutse mumazi na ON +) ni ions yuzuye na chloride iny. Nukuvuga, igihe HPMC yashyizwe mumazi, ntabwo izatandukanya ions, ariko ibaho muburyo bwa molekile.
