bituma iba polymer y'ingenzi mu nganda zigezweho.

1. Ethyl Cellulose (EC) ni iki?

1.1 Ibisobanuro bya Ethyl Cellulose

Ethyl Cellulose (EC) ni ether ya selulosi ikorwa binyuze mu gusimbuza amatsinda ya hydroxyl muri selulosi karemano n'amatsinda ya ethyl binyuze mu buryo bwo guhindura imiti.

Gusimbuza ethyl biha selulose imiterere mishya:

• Uburyo bwo gushonga neza kw'ibinyabutabire bikomoka ku bimera
• Kugabanuka k'ubuhanga bwo kumenya amazi
• Ubushobozi bwiza bwo gukora filime

4. Uburyo bwo gukora Ethyl Cellulose

Gukora ethyl cellulose muri rusange bikubiyemo intambwe nyinshi:

Intambwe ya 1: Gutegura selulosi

Selulose ifite isuku nyinshi itoranywa nk'ibikoresho fatizo.

Amasoko arimo:

• Igitambaro cy'ipamba
• Ifu y'ibiti

Intambwe ya 2: Guhindura alkali

Selulosi ikorana n'ibinyabutabire bya alkaline kugira ngo ikore amatsinda ya hydroxyl.

Intambwe ya 3: Guhindura imiterere y'amazi

Selulosi ikorana n'ibintu bihindura imiterere y'umubiri kugira ngo ishyiremo amatsinda ya ethyl.

Intambwe ya 4: Gusukura

Icyo gicuruzwa cyogejwe kandi kigasukurwa.

Intambwe ya 5: Kumisha no gusya

Ifu ya nyuma ya EC irakorwa.

• Imitako y'imiti
• Imiti ikoreshwa mu kugenzura ikoreshwa
• Udupfukanto tw'ibiribwa
• Wino yo gucapa
• Amarangi yo mu nganda

Ikibazo cya 4: Kuki Ethyl Cellulose ikoreshwa mu binini bya farumasi?

Kubera ko EC itanga filime nziza kandi ikagenzura igipimo cyo gusohora imiti.

Q5: Ni iki gitandukanya Ethyl Cellulose na HPMC?

HPMC irashonga mu mazi kandi ikoreshwa cyane nk'umuti ugabanya ubushyuhe kandi ugabanya ubushyuhe, mu gihe EC idapfa amazi kandi ikoreshwa cyane cyane mu mafirime yo kurinda no kurekura ubushyuhe mu gihe kirekire.

Ethyl Cellulose (EC) ni ubwoko bwa cellulose bukora neza cyane bufite imiterere yihariye irimo:

• Gukora filime neza cyane
