1. Ubushyuhe bwamazi
Ukurikije umurongo wo kurekura ubushyuhe bwa hydration mugihe, inzira ya hydrata ya sima isanzwe igabanyijemo ibyiciro bitanu, aribyo, igihe cyambere cyo gutangira (0 ~ 15min), igihe cyo kwinjiza (15min ~ 4h), igihe cyo kwihuta no gushiraho (4h ~ 8h), kwihuta no gukomera (8h ~ 24h), nigihe cyo gukira (1d ~ 28d).
Ibisubizo by'ibizamini byerekana ko mugihe cyambere cyo kwinjiza (ni ukuvuga igihe cyambere cyo gutanga amazi), mugihe umubare wa HEMC ari 0.1% ugereranije na sima yubusa, impinga ya exothermic pex ya slurry iratera imbere kandi impinga iriyongera cyane. Iyo umubare waHEMCyiyongera Kuri Iyo iri hejuru ya 0.3%, impinga ya mbere ya exothermic peak ya slurry iratinda, kandi agaciro kimpanuka gahoro gahoro gahoro gahoro hamwe no kwiyongera kwa HEMC; HEMC biragaragara ko izadindiza igihe cyo kwinjiza nigihe cyo kwihuta cya sima ya sima, kandi nibirimo byinshi, igihe kinini cyo kwinjiza, niko igihe cyihuta cyihuta, kandi ntoya ntoya; ihinduka ryibintu bya selile nta ngaruka zigaragara ku burebure bwigihe cyo kwihuta nigihe cyigihe cyo gutuza kwa sima, nkuko bigaragara ku gishushanyo cya 3 (a) Herekanwe ko ether ya selulose ishobora kandi kugabanya ubushyuhe bwa hydrata ya paste ya sima mugihe cyamasaha 72, ariko mugihe ubushyuhe bwa hydrata burenze amasaha 36, ihinduka ryibintu bya selile ya selile.
Igishushanyo.3 Itandukanyirizo ryubushyuhe bwo gusohora ubushyuhe bwa sima paste hamwe nibintu bitandukanye bya selile ya selile (HEMC)
2. M.imiterere ya echanical：
Mu kwiga ubwoko bubiri bwa selile ya selile ifite viscosities ya 60000Pa · s na 100000Pa · s, byagaragaye ko imbaraga zo gukomeretsa za minisiteri yahinduwe ivanze na methyl selulose ether yagabanutse buhoro buhoro hamwe niyongera ryibirimo. Imbaraga zo guhonyora za minisiteri yahinduwe ivanze na 100000Pa · s viscosity hydroxypropyl methyl selulose ether yiyongera mbere hanyuma ikagabanuka niyongera ryibirimo (nkuko bigaragara ku gishushanyo 4). Irerekana ko kwinjiza methyl selulose ether bizagabanya cyane imbaraga zo gukomeretsa za sima. Umubare munini ni, imbaraga zizaba nto; ntoya ya viscosity, niko ingaruka nyinshi ziterwa no gutakaza imbaraga za minisiteri yo kwikuramo; hydroxypropyl methyl selulose ether Iyo dosiye iri munsi ya 0.1%, imbaraga zo kwikuramo za minisiteri zirashobora kwiyongera muburyo bukwiye. Iyo dosiye irenze 0.1%, imbaraga zo kwikuramo za minisiteri zizagabanuka hamwe no kwiyongera kwa dosiye, bityo dosiye igomba kugenzurwa kuri 0.1%.
Igishushanyo.4 3d, 7d na 28d imbaraga zo kwikuramo MC1, MC2 na MC3 zahinduwe na sima ya sima
.
3. C.igihe：
Mugupima igihe cyagenwe cya hydroxypropyl methylcellulose ether hamwe nubukonje bwa 100000Pa · s muburyo butandukanye bwa paste ya sima, byagaragaye ko hamwe no kwiyongera kwa dosiye ya HPMC, igihe cyambere cyo kugena nigihe cyo gushyiraho sima ya sima cyongerewe igihe. Iyo kwibandaho ari 1%, igihe cyambere cyo gushiraho kigera kuminota 510, naho igihe cyanyuma cyo gushiraho kigera kuminota 850. Ugereranije nicyitegererezo cyubusa, igihe cyambere cyo gushiraho cyongerewe niminota 210, naho igihe cyo gushiraho cyongerewe iminota 470 (nkuko bigaragara ku gishushanyo 5). Yaba HPMC ifite viscosity ya 50000Pa s, 100000Pa s cyangwa 200000Pa s, irashobora gutinza igenamigambi rya sima, ariko ugereranije na ether eshatu za selile, igihe cyo gutangira nigihe cyo gushiraho cyongerewe igihe cyo kwiyongera, nkuko bigaragara ku gishushanyo cya 6 cyerekanwe. Ni ukubera ko selile ya selile yamamaye hejuru yubutaka bwa sima, ikabuza amazi guhura nuduce twa sima, bityo bikadindiza amazi ya sima. Ninini cyane ya selulose ether, niko umubyimba wa adsorption hejuru yubutaka bwa sima, kandi ningaruka zikomeye zo kudindiza.
Igishushanyo.5 Ingaruka za selile ya ether mugushiraho igihe cya minisiteri
Igishushanyo.6 Ingaruka zijimye zitandukanye za HPMC mugihe cyo gushiraho paste ya sima
(MC-5 (50000Pa · s), MC-10 (100000Pa · s) na MC-20 (200000Pa · s))
Methyl selulose ether na hydroxypropyl methyl selulose ether bizongerera cyane igihe cyo gushiraho sima ya sima, ishobora kwemeza ko sima ya sima ifite umwanya uhagije namazi yo gufata reaction, kandi bigakemura ikibazo cyimbaraga nke nicyiciro cya nyuma cya sima nyuma yo gukomera. ikibazo.
4. Kubika amazi:
Ingaruka yibigize selulose ether mukubika amazi yarizwe. Byagaragaye ko hamwe no kwiyongera kwibintu bya selile ya selile, igipimo cyo gufata amazi ya minisiteri cyiyongera, kandi iyo ibigize selile ya selile irenze 0,6%, igipimo cyo gufata amazi gikunda kuba gihamye. Ariko, iyo ugereranije ubwoko butatu bwa ethers ya selile (HPMC hamwe nubwiza bwa 50000Pa s (MC-5), 100000Pa s (MC-10) na 200000Pa s (MC-20)), ingaruka zijimye ku gufata amazi ziratandukanye. Isano iri hagati yo gufata amazi ni: MC-5.
