Nigute ushobora guhitamo hydroxypropyl methylcellulose kubwimbere ninyuma yo hanze

Nigute ushobora guhitamo neza HPMC

1. Ukurikije icyitegererezo: Ukurikije formulaire zitandukanye za putties zitandukanye, moderi ya viscosity ya hydroxypropyl methylcellulose na methylcellulose nayo iratandukanye.Bakoreshwa kuva 40.000 kugeza 100.000.Muri icyo gihe, fibre yibimera ntishobora gusimbuza uruhare rwabandi bahuza, kongeraho selile ether ntabwo bivuze ko ibigize izindi binderi bishobora kugabanuka.

2. Ukeneye amazi akonje akwirakwiza selulose ether: Ether ya Cellulose (harimo hydroxypropyl methylcellulose na methylcellulose) ni surfactant ifite ubukonje bwinshi nyuma yo guseswa.Ninimpamvu yiyi miterere ko niba ether ya selile isanzwe yongewe mumazi, byoroshye gukora umupira, kandi hanze yumupira washyizwe mumuti mwinshi cyane, kandi imbere urapfunyitse, kandi biragoye kugirango amazi yinjire, bivamo gushonga nabi..Ether ya selile yakozwe na selile (ishobora gutinza guseswa) ntabwo izaba imeze gutya, kandi irashobora gukwirakwizwa neza mumazi akonje (gutinda gushonga, hanyuma buhoro buhoro nyuma yo gutatana).Nibyiza guhitamo kumva itandukaniro ryavuzwe haruguru.

1. Kubintu byumye bivanze byimbere hamwe nurukuta rwinyuma rushyizwe hejuru, kubera ko selile ya selile yatatanye neza mubikoresho mugihe cyo kuvanga byumye, ntihazabaho agglomeration.Kubwibyo, birasabwa gukoresha ubwoko busanzwe (ubwoko bwo gukwirakwiza amazi adakonje), kubera ko igipimo cyo gusesa cyubwoko busanzwe cyihuta kuruta icyogukwirakwiza amazi akonje, bigabanya igihe cyo gutegereza kuvanga ibishishwa byubaka.

2. Kugirango hategurwe ibishishwa bishonga mu buryo butaziguye ether ya selile (harimo hydroxypropyl methylcellulose na methylcellulose) mumazi ikayivanga nibindi bikoresho, birasabwa gukoresha ubwoko bukwirakwiza amazi akonje ubwoko bwa selile ether.Ether ivura hejuru ya selile irashobora gukwirakwizwa neza mumazi akonje kandi igashonga (irashobora gutinda guseswa)
