Ibibazo byo gukoresha methyl selulose

Methyl selulose ni impfunyapfunyo ya sodium carboxymethyl selulose. Ikoreshwa cyane cyane mubiribwa, ubwubatsi, imiti, ubukorikori, bateri, ubucukuzi bw'amabuye y'agaciro, gutwikira, gukora impapuro, gukaraba, amenyo ya miti ya buri munsi, gucapa imyenda no gusiga irangi, gucukura amavuta, nibindi mumurima. Igikorwa nyamukuru nugukora nkibibyibushye, bigumana amazi, binder, lubricant, agent uhagarika, emulsifier, umutwaro wibinyabuzima, materix ya tablet, nibindi. Ni gute methyl selulose yagereranywa mugihe ikoreshwa?

1. Methylcellulose ubwayo ni ifu yumye yumye, idashobora gukoreshwa munganda. Igomba gushonga mumazi mbere kugirango ikore kole ibonerana neza mbere yuko ishobora kuvangwa na minisiteri hanyuma igakoreshwa muburyo bumwe bwo kuvura, nko gushiraho amabati.

2. Ni ikihe kigereranyo cya methyl selulose? Ifu: amazi agomba gutunganyirizwa icyarimwe ukurikije igipimo cya 1: 150-200, hanyuma akayungurura ibihimbano, mugihe wongeyeho ifu yumye ya PMC mugihe ukurura, kandi irashobora gukoreshwa nyuma yisaha 1.

3. Niba methyl selulose ikoreshwa muburyo bwo kuvura neza, igipimo cya kole gikeneye gukurikira → kole: sima = 1: 2.

4. Niba methyl selulose ikoreshwa nka sima ya sima kugirango irwanye, igipimo cya kole kigomba gukurikizwa → kole: sima: umucanga = 1: 3: 6.

Tugomba kwitondera ibibazo bimwe na bimwe mugihe dukoresha methyl selulose:

1. Mbere yo gukoresha methyl selulose kumugaragaro, ugomba kubanza kureba ibisobanuro na moderi. Moderi zitandukanye zikoresha uburyo butandukanye: iyo pH> 10 cyangwa <5, ubwiza bwa kole buri hasi. Imikorere niyo ihamye cyane iyo pH = 7, kandi ubukonje buzamuka vuba mugihe ubushyuhe buri munsi ya 20 ° C; iyo ubushyuhe buri hejuru ya 80 ° C, colloid izatandukana nyuma yo gushyuha igihe kirekire, ariko ubukonje buzagabanuka cyane.

2. Methyl selulose irashobora gutegurwa namazi akonje cyangwa amazi ashyushye ukurikije igipimo cyagenwe. Mugihe witegura, ugomba kongeramo amazi mugihe ukangura. Wibuke kongeramo amazi yose hamwe nifu ya PMC icyarimwe. Birakwiye ko tumenya ko urwego shingiro rugomba guhuzwa rugomba gusukurwa hakiri kare, kandi umwanda, irangi ryamavuta, hamwe nuburinganire bigomba gukemurwa mugihe gikwiye.
