Cellulose yo kubaka ninyongera ikoreshwa cyane mubikorwa byubwubatsi. Cellulose yo kubaka ikoreshwa cyane cyane mumashanyarazi yumye. Kwiyongera kwa selile ya ether iri hasi cyane, ariko irashobora kunoza cyane imikorere ya minisiteri itose kandi ikagira ingaruka kumyubakire ya minisiteri. Imikorere igomba kwitabwaho mugukoresha. Nibihe bintu bifatika bya selile yubaka, kandi niyihe nzira yo kubaka selile yo kubaka? Niba utazi byinshi kumiterere nuburyo bwo kubaka selile yokubaka, reka turebere hamwe.
Nibihe bintu bifatika bya selile yo kubaka:
1. Kugaragara: ifu yera cyangwa itari yera.
2. Ingano y'ibice; igipimo cyatsinze mesh 100 kirenze 98.5%; igipimo cya pass ya 80 mesh irenze 100%.
3. Ubushyuhe bwa Carbone: 280-300 ° C.
4. Ubucucike bugaragara: 0.25-0.70 / cm3 (mubisanzwe hafi 0.5g / cm3), uburemere bwihariye 1.26-1.31.
5. Ubushyuhe bwo guhindura ibara: 190-200 ° C.
6. Ubushyuhe bwo hejuru: 2% igisubizo cyamazi ni 42-56dyn / cm.
7. Gushonga mumazi hamwe na solve zimwe, nkigipimo gikwiye cya Ethanol / amazi, propanol / amazi, trichloroethane, nibindi. Ibisubizo byamazi birakora hejuru. Gukorera mu mucyo mwinshi, imikorere ihamye, ibisobanuro bitandukanye byibicuruzwa bifite ubushyuhe butandukanye bwa gel, guhinduka gukemuka hamwe nubwiza, uko ubukonje bugenda bugabanuka, niko bigenda byiyongera, ibisobanuro bitandukanye bya HPMC bifite itandukaniro mubikorwa, kandi iseswa rya HPMC mumazi ntabwo bigira ingaruka na pH agaciro.
8. Hamwe no kugabanya ibirimo vitamine, ingingo ya gel iriyongera, amazi ya HPMC aragabanuka, kandi ibikorwa byo hejuru nabyo biragabanuka.

Ni ubuhe buryo bwo kubaka selile yo kubaka:
1. urukuta bityo uzamure imbaraga zo guhuza urukuta nurubaho rwa polystirene.
2.
3. Manika umurongo werekana: Kumanika insinga zicyuma zerekana ibyuma kumpande nini (imfuruka zo hanze, imfuruka zimbere) zinkuta zinyuma yinyubako nahandi hantu hakenewe, hanyuma umanike imirongo itambitse kumwanya ukwiye kuri buri igorofa kugirango ugenzure uburebure nuburinganire bwa ikibaho cya polystirene.
4.
5. Shyiramo umwenda wa gride washenywe: Ahantu hose hagaragara kuruhande rwikibaho cya polystirene (nko guhuza kwaguka, guhuza amazu yo guturamo, guhuza ubushyuhe hamwe nizindi suture kumpande zombi, inzugi nidirishya) bigomba kuvurwa nigitambaro cya gride. .
6. Ikibaho cya polystirene gifatika: Menya ko gukata ari perpendicular hejuru yubuyobozi. Ingano itandukanijwe igomba kuba yujuje ibyangombwa bisabwa, kandi ingingo zubuyobozi bwa polystirene ntizigomba gusigara kumpande enye zumuryango nidirishya.
7. Gushiraho inanga: umubare w'inyanja urenze 2 kuri metero kare (wiyongereye kugera kuri 4 ku nyubako ndende).
8.
Mu bwoko bwa selile ikoreshwa mu bwubatsi, ether ya selile ikoreshwa na hydroxypropyl methylcellulose mu ifu yumye yumye ni hydroxypropyl methylcellulose ether. Hydroxypropyl methylcellulose igira uruhare runini mu gufata amazi, kubyimba no kunoza imikorere yubwubatsi bwa poro yumye.
