1. Ni ubuhe buryo bukoreshwa na hydroxyproppopyl methylcellse (HPMC)?
HPMC ikoreshwa cyane mu bikoresho by'ubwubatsi, amatwi, ibisohokaga sinzoma, ubuvuzi, ubuvuzi, ibiryo, ubuhinzi, kwisiga, itabi n'izindi nganda. HPMC irashobora kugabanywamo urwego rwubwubatsi, amanota yibiribwa hamwe nicyiciro cya farumasi ukurikije intego. Kugeza ubu, ibyinshi mu bicuruzwa byo mu rugo ni urwego rwo kubaka. Mu rwego rwo kubaka, ifu ya Protyite ikoreshwa mu mubare munini, hafi 90% ikoreshwa mu ifu ya Prowder, kandi ibisigaye bikoreshwa muri sirvar.
2. Nuwuhe mpumuro ya hydroxypropyl methylcellse (HPMC)?
HPMC yakozwe nuburyo bworoshye bukoresha toluene na isopropanol nkuko bitanga. Niba gukaraba atari byiza cyane, hazabaho impumuro zisigaye.
3. Ni ubuhe buryo bwo kuvugurura bwa hydroxypropyl methylcellse (HPMC)?
Uburyo bushyushye bwamazi: Kubera ko HPMC idashonga mumazi ashyushye, HPMC irashobora gutatanya amazi ashyushye mugihe cyambere, hanyuma arasa 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) 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.
. HPMC nyinshi zakozwe muri Hebei ni mesh 80. Impeta nziza, muri rusange ivuga, ibyiza.
. Umucyo wohererezanya, ibyiza, byerekana ko hari ibicucu bitarenze. . 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 irihe tandukaniro riri hagati yubwoko bukonje-amazi ako kanya hamwe nuburyo bushyushye bwa hydroxypropyl methylcellse mubikorwa byumusaruro?
Ubwoko bwihuse bwa HPMC buvurwa neza na glegoxal, kandi ikwirakwizwa vuba mumazi akonje, ariko ntabwo rwose ishonga. Gusa birashonga mugihe ubukuru bwiyongera. Ubwoko bwihuse ntibufite ubuvuzi bugaragara hamwe na glegox. Niba umubare wa Glyoxal ari munini, gutatanya bizahita byihuta, ariko viscosity iziyongera buhoro, kandi niba amafaranga ari nto, ibinyuranye nabyo bizaba ukuri.
6. Ni ubuhe buryo bukwiye bwa hydroxyproppopyl methylcellse (HPMC)?
Powett ifu muri rusange yubura 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 gusby, abantu benshi bahangayikishijwe nibi 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.
Ongeraho amazi kuri powder ifu hanyuma uyishyire kurukuta ni reaction yimiti, kuko ibintu bishya byashizweho. Niba ukuye ifu ya Putty kurukuta kuva kurukuta, kuyitontobo mu ifu, kandi ukongera kuyikoresha, ntabwo bizakora kuko ibintu bishya (Calcium Carbonate) yashizweho. ).
Ibice byingenzi bya Ifu ya Ash Calcium ni: imvange ya ca (Oh) 2, Caito na Calci3 yakozwe mu mazi, mugihe cya HPMC 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.
11. Ubushyuhe bwa GEL ni ubuhe bushyuhe bwa hydroxypropyl methylcellse bijyanye?
Ubushyuhe bwa GEL bwa HPMC bufitanye isano nuburyo bwabwo, butoya ibirimo, hejuru yubushyuhe bwa gel.
12. Hari umubano uri hagati yigitonyanga cya prowder ifu na HPMC?
Ifu yo gutakaza ifu ya Prowty ifitanye isano ahanini nubwiza bwa calcium ya Ash, kandi ntaho ihuriye na HPMC. Ibirimo byo hasi bya calcium calcium hamwe nigipimo kidakwiye cya cao na ca (oh) 2 mumibura yijimye bizatera igihombo cya powder. Niba bifite aho bihuriye na HPMC, niba HPMC ifite agafungo k'amazi mazi, izanakaza igihombo cy'ifu.
13. Ni irihe tandukaniro riri hagati yubwoko bukonje-amazi ako kanya hamwe nuburyo bushyushye bwa hydroxypropyl methylcellse mubikorwa byumusaruro?
Ubwoko bwihuse bwa HPMC buvurwa neza na glegoxal, kandi ikwirakwizwa vuba mumazi akonje, ariko ntabwo rwose ishonga. Gusa birashonga mugihe ubukuru bwiyongera. Ubwoko bwihuse ntibufite ubuvuzi bugaragara hamwe na glegox. Niba umubare wa Glyoxal ari munini, gutatanya bizahita byihuta, ariko viscosity iziyongera buhoro, kandi niba amafaranga ari nto, ibinyuranye nabyo bizaba ukuri.
