Kugeza ubu, ubwiza bwa hydroxypropyl methylcellulose yo mu gihugu buratandukanye cyane, kandi igiciro kiratandukanye cyane, bigatuma abakiriya bahitamo neza.HPMC yahinduwe yisosiyete imwe yamahanga nigisubizo cyimyaka myinshi yubushakashatsi.Kwiyongera kubintu bya tronc birashobora kunoza imikorere yubwubatsi no kunoza imikorere.Nibyo, bizagira ingaruka kubindi bintu, ariko mubisanzwe nukuvuga neza;Intego yonyine yo kongeramo ibindi bikoresho ni ukugabanya ibiciro, bigatuma kugabanuka cyane kwamazi, guhuriza hamwe nibindi bintu byibicuruzwa, bikavamo ibibazo byinshi byubwubatsi.
Hariho itandukaniro rikurikira hagati ya HPMC yera na HPMC yasambanijwe:
1. HPMC isukuye igaragara neza kandi ifite ubwinshi buke, kuva kuri 0.3-0.4g / ml;gusambana HPMC ifite flux nziza kandi ikumva iremereye, bigaragara ko itandukanye nibicuruzwa nyabyo mubigaragara.
2. Igisubizo cyamazi ya HPMC kirasobanutse, kohereza urumuri rwinshi, nigipimo cyo gufata amazi ≥ 97%;gusambana HPMC igisubizo cyamazi ni ibicu, kandi igipimo cyo gufata amazi kiragoye kugera kuri 80%.
3. HPMC itanduye ntigomba kunuka ammonia, ibinyamisogwe n'inzoga;gusambana HPMC irashobora guhumurirwa muburyo bwose, nubwo itaryoshye, izumva iremereye.
4. Ifu ya HPMC isukuye ni fibrous munsi ya microscope cyangwa ikirahure kinini;HPMC yasambanijwe irashobora kugaragara nkibintu bya granulaire cyangwa kristu munsi ya microscope cyangwa ikirahure kinini.
Uburebure budashobora kurenga 200.000?
Impuguke n’intiti nyinshi zo mu gihugu zasohoye impapuro zemeza ko umusaruro wa HPMC ugabanywa n’umutekano w’ibikoresho byo mu rugo no gufunga kashe, uburyo bwihuse n’umusaruro muke, kandi inganda zisanzwe ntizishobora gutanga ibicuruzwa bifite ubwiza burenga 200.000.Mu mpeshyi, ntibishoboka no gukora ibicuruzwa bifite ubwiza burenga 80.000.Bizera ko ibyo bita ibicuruzwa 200.000 bigomba kuba ibicuruzwa byimpimbano.
Impuguke zimpaka ntabwo zifite ishingiro.Ukurikije uko umusaruro wabanjirijwe mu gihugu, imyanzuro yavuzwe haruguru irashobora rwose gufatwa.
Urufunguzo rwo kongera ubwiza bwa HPMC nugufunga cyane reaktor hamwe nigitutu cyinshi kimwe nibikoresho fatizo byiza.Umuyaga mwinshi urinda kwangirika kwa selile na ogisijeni, kandi imiterere yumuvuduko ukabije utera kwinjirira muri etherification yinjira muri selile kandi ikemeza ko ibicuruzwa bihuje.
Icyerekezo cyibanze cya 200000cps hydroxypropyl methylcellulose:
2% igisubizo cyamazi viscosity 200000cps
Ibicuruzwa byera ≥98%
Uburyo bwa Methoxy 19-24%
Hydroxypropoxy ibirimo: 4-12%
200000cps hydroxypropyl methylcellulose ibiranga:
1. Kubika amazi meza hamwe no kubyibuha kugirango habeho amazi meza.
2. Imbaraga zihuza cyane ningaruka zikomeye zo kwinjiza umwuka, kubuza neza kugabanuka no guturika.
3. Gutinda kurekura ubushyuhe bwa hydrata ya sima, gutinza igihe cyagenwe, no kugenzura igihe gikora cya sima.
4. Kunoza amazi ya pompe ya pompe, kunoza rheologiya, no gukumira amacakubiri no kuva amaraso.
5. Ibicuruzwa bidasanzwe, bigamije kubaka ubushyuhe bwo hejuru bwubushyuhe mu cyi, kugirango habeho amazi meza ya shitingi nta gusiba.
Bitewe no kugenzura isoko ridahwitse, irushanwa mu nganda za minisiteri riragenda rikomera.Mu rwego rwo guhaza isoko, abacuruzi bamwe bavanze ibintu byinshi bihendutse kugirango babone etherulose ihendutse.Hano, umwanditsi ategetswe kwibutsa abakiriya kudakurikirana buhumyi ibiciro biri hasi, kugirango badashukwa Gushukwa, biganisha ku mpanuka zubwubatsi, kandi amaherezo igihombo kiruta inyungu.
Uburyo busanzwe bwo gusambana nuburyo bwo kumenya:
.
Uburyo bwo kumenyekanisha: Bitewe nibiranga amide, ubu bwoko bwa selile ether igisubizo akenshi bugira ibintu bifatika, ariko ether nziza ya selile ntishobora kugaragara nkumugozi nyuma yo guseswa, igisubizo ni nka jelly, ibyo bita gukomera ariko bitajyanye.
(2) Ongeramo ibinyamisogwe kuri selile ether.Ibinyamisogwe muri rusange ntibishobora gushonga mumazi, kandi igisubizo akenshi gifite itumanaho rike.
Uburyo bwo kumenyekanisha: Kureka selile ya ether igisubizo hamwe na iyode, niba ibara rihindutse ubururu, birashobora gufatwa ko krahisi yongeyeho.
(3) Ongeramo ifu ya alcool ya polyvinyl.Nkuko twese tubizi, igiciro cyisoko ryifu ya polyvinyl inzoga nka 2488 na 1788 akenshi usanga ari munsi ugereranije na selile ya selile, kandi kuvanga ifu yinzoga ya polyvinyl bishobora kugabanya ikiguzi cya selile.
Uburyo bwo Kumenyekanisha: Ubu bwoko bwa selile ether akenshi ni granular kandi yuzuye.Gucika vuba n'amazi, hitamo igisubizo ukoresheje inkoni yikirahure, hazabaho ibintu bigaragara byumugozi.
Incamake: Bitewe nuburyo bwihariye hamwe nitsinda ryayo, kubika amazi ya selile ya selile ntibishobora gusimburwa nibindi bintu.Ntakibazo cyuzuza ubwoko ki, mugihe cyose kivanze kubwinshi, kubika amazi bizagabanuka cyane.Ingano ya HPMC ifite ubukonje busanzwe bwa 10W muri minisiteri isanzwe ni 0.15 ~ 0.2 and, naho igipimo cyo gufata amazi ni> 88%.Kuva amaraso birakomeye.Kubwibyo, igipimo cyo gufata amazi nicyo kimenyetso cyingenzi cyo gupima ubuziranenge bwa HPMC, cyaba cyiza cyangwa kibi, igihe cyose cyongewe kuri minisiteri, bizagaragara neza iyo urebye.
