Isubusi nkeya HPMC: HPMC 400 ikoreshwa cyane muguhitamo minisiteri yo kwishyira hamwe, ariko muri rusange zitumizwa mu mahanga.
Impamvu: Ibyatsi ni bike, nubwo kugumana amazi ari bibi, ariko urwego ni rwiza, kandi ubucucike bwa mirtar ni bwinshi.
Hagati no hasi cyane:hydroxypropyl methylcellseHPMC 20000-40000 ikoreshwa cyane cyane mugutangana, igent, anti-gutontoma, inkelasiyo yubushyuhe ihuza minisiteri, nibindi.
Impamvu: ibikorwa byiza, kongerera amazi, gutandukana kwinshi.
1. Niyihe ntego nyamukuru ya hydroxypropyl methylcellse (HPMC)?
- HPMC ikoreshwa cyane mu bikoresho byo kubaka, ku nkoni, ibisohokaga sinzome, ubuvuzi, ubuvuzi, ibiryo, kwisiga, itabi, itabi n'izindi nganda. HPMC irashobora kugabanywamo muri: Icyiciro cyo kubaka, amanota yibiribwa hamwe nicyiciro cya farumasi ukurikije intego. Kugeza ubu, ibyinshi mu bicuruzwa byo mu rugo ni urwego rwo kubaka. Mu rwego rwo kubaka, umubare w'ifu ya prowy ni munini, 90% ukoreshwa mu ifu ya prowder, kandi ahasigaye hakoreshwa kuri sima na kole.
2. Hariho ubwoko bwinshi bwa hydroxypropyl methylcellse (HPMC), kandi ni irihe tandukaniro mu gukoresha?
- Amafaranga: HPMC irashobora kugabanywamo ubwoko bwihuse hamwe nubwoko bushyushye. Ibicuruzwa byubwoko ako kanya byatatanye vuba mumazi akonje kandi uzimire mumazi. Muri iki gihe, amazi adafite ubuyobe, kuko HPMC yatatanye gusa mumazi kandi nta gusenywa nyabyo. Nyuma yiminota 2, viscolity yamazi yiyongereye buhoro buhoro, ikora virusi ya Transcous Colloid. Ibicuruzwa bishonga ubushyuhe, mugihe uhuye namazi akonje, birashobora gutatana vuba mumazi ashyushye, ukabura mumazi ashyushye. Iyo ubushyuhe bugabanutse ku bushyuhe runaka (ibicuruzwa byikigo byacu ni dogere 65), vinosity iragaragara buhoro kugeza igihe ikora virusi iboneye. Ubwoko bushyushye buke burashobora gukoreshwa gusa muri pattle ifu na minisiteri. Mu mazi na paund, ibintu bihurira ibintu bizabaho kandi ntibishobora gukoreshwa. Ubwoko bwihuse bufite uburyo bwagutse bwa porogaramu. Irashobora gukoreshwa mubukonje na minisiteri, kimwe no muri kole yamazi kandi irangi, nta binyuranye.
3. Ni ubuhe buryo bwo kuvugurura bwa hydroxypropyl methylcellse (HPMC)?
- Uburyo bwo kuvugurura amazi ashyushye: Kubera ko HPMC idashonga mumazi ashyushye, HPMC irashobora gutatanya mumazi ashyushye mugihe cyambere, hanyuma ashongeshe cyane iyo akonje. Uburyo bubiri busanzwe busobanurwa kuburyo bukurikira:
1) Shyira umubare ukenewe wamazi ashyushye muri kontineri no gushyuha kugeza kuri 70 ° C. HydroxyPropyl Methylcellse yongeyeho buhoro buhoro hamwe no gukangura buhoro, HPMC yareremba hejuru y'amazi, hanyuma igacekwa buhoro buhoro ihagarikwa.
2) Noneho ongeraho umubare usigaye wamazi akonje kumazi ashyushye mumazi, uruvange rwarakonje nyuma yo gukangura.
Uburyo bwo kuvanga powder: Kuvanga ifu ya HPMC hamwe nizindi mboga, ivange neza hamwe na mixeer, hanyuma wongere amazi kugirango ushongesheje, kuko hari HPMC ntoya muri buri inguni nto. Ifu izashonga ako kanya guhura namazi. - Uburyo bukoreshwa na PANT PATDER ifu hamwe nabakora umuryango. . ]
4. Nigute nakura ireme rya hydroxyproppopyl methylcellse (HPMC) byoroshye kandi byimazeyo?
- Ariko, ibicuruzwa byinshi byiza bifite channene nziza. . Byinshi muri HPMC yakorewe muri Hebei ni mesh 80. Ibyiza byiza, nibyiza. . Isumbabyose yoherezwa, ibyiza, byerekana ko hari ibintu bidasubirwaho muri byo. Ibijyanye na reactique ya reaction ni byiza, kandi reacttor itambitse cyane, ariko ntishobora kuvugwa ko ireme rya reactique riruta iy'umuyoboro utambitse, kandi haribintu byinshi byerekana ibicuruzwa. (4) Imbaraga zihariye: nini nini nini, nziza cyane. Uburemere bwihariye ni bunini, muri rusange kubera ko hydroxyPropylepyle iri hejuru, kandi hydroxyPropyl ibirimo ni hejuru, ihohoterwa ry'amazi ni ryiza.
5. Ingano ya hydroxypropyl methylcellse (HPMC) mubutaka bwa Putty?
- Amafaranga: Umubare wa HPMC ukoreshwa mubikorwa bifatika biratandukanye bitewe nikirere, ubushyuhe, ubwiza bwa Holcium yaho, formulaire ya power powder hamwe nabakiriya ". Muri rusange, ni hagati ya kg 4 na 5 kg. Kurugero, ibyinshi mu ifu ya Putty muri Beijing ni 5 kg; Ibyinshi muri powder iko muri Guizhou ni 5 kg mu cyi na 4,5 kg mu gihe cy'itumba;
6. Ni ubuhe buryo bukwiye bwa hydroxyproppopyl methylcellse (HPMC)?
--SANZWE: Poitt Powder muri rusange 100.000 Yuan, kandi minisiteri irasaba cyane, kandi biroroshye gukoresha saa 150.000. Byongeye kandi, uruhare runini rwa HPMC ni ugumana amazi, gukurikirwa no kubyimba. Mu ifu ya Putty, igihe cyose ihohoterwa rishingiye ku mazi ari ryiza kandi ko urusyo ari hasi (70.000-80.000), birashoboka. Birumvikana ko urusyo ari hejuru, kandi ihohoterwa rishinzwe gusuhuza amazi ni ryiza. Iyo visosity irenze 100.000, ingaruka zo gusuku kuri gereza yo kugumana amazi ntabwo ari nyinshi.
7. Nibihe bipimo nyamukuru bya tekiniki bya HydroxyPropyl Methylcellse (HPMC)?
--SANGR: HydroxyPropyl Ibirimo no kureba, abakoresha benshi bita kuri ibi bipimo byombi. Isumbuye ya hydroxyPropyle, ni byiza kugumana amazi. Ubu buryo bwo hejuru, kugumana amazi, ugereranije (aho kuba byuzuye) neza, kandi birakabije, gutsindwa cyane, gukoresha neza minisiteri.
8. Nibihe bikoresho nyamukuru bya hydroxyproppopyl methylcellse (HPMC)?
- A: Ibikoresho nyamukuru bya hydroxypropyl methylcellus (HPMC): Ipamba yatunganijwe, aside oxide, aside, toluene, isopropanol, nibindi
9. Ni uruhe ruhare nyamukuru rwa HPMC mu buryo bwo gusaba ifu ya Putty, kandi hari chimie?
- HPMC: HPMC ifite imirimo itatu yo kubyimba, kugumana amazi no kubaka ifu ya Putty. Kwinginga: Ubugari bushobora kwiyongera guhagarika, komeza umwerureko kandi uhamye, kandi urwanye ubwoba. Kugumana amazi: kora ifu ya putty yumye buhoro, kandi ifashe reaction ya calcium ya Ash munsi yigikorwa cyamazi. Kubaka: Ubugari bufite ingaruka zo gusiga, ishobora gutuma ifu ya LIPTY igira ibikorwa byiza. HPMC ntabwo yitabira imiti iyo ari yo yose kandi igira uruhare rufasha. Ongeraho amazi kuri powder ifu hanyuma uyishyire kurukuta ni reaction yimiti. Kubera gushinga ibintu bishya, fata ifu ya Putty kurukuta ku rukuta, uyasya mu ifu, hanyuma ukoreshe. Ntabwo izakora, kuko ibintu bishya (karubone ya calcium) byashizweho. ) hejuru. Ibice byingenzi bya Ifu ya Ash Calcium ni: imvange ya CA (OH) 2, CAO na CAO + H2O = HO2 = Caco3 ↓ + Calcium ya H2O Mu mazi no mu kirere munsi y'ibikorwa bya CO2, Calcium Carbote yakozwe, mu gihe HPMC igumana amazi gusa kandi igafasha realic ya Ash calcium ya Ash, kandi ntabwo yitabira reaction yonyine.
10. Hpmc ntabwo ari selile ya selile, none niki kitari icic?
- Igisubizo: Mu magambo ya Palaman, ntabwo ari ions ni ibintu bidakora ionize mumazi. Ioosiyo bivuga inzira ya electrolyte itandukanijwe na Eon-yishyurwa kubuntu muburyo bwihariye (nk'amazi, inzoga). Kurugero, sodium chloride (nacl), umunyu uriga buri munsi, shoza mumazi yimuka ya sodium yigenga. Ni ukuvuga, igihe HPMC yashyizwe mumazi, ntabwo itandukanya ions, ariko ibaho muburyo bwa molekile.
