Ethers ya Cellulose niki kandi kuki ikoreshwa?
Ether ya selile ni polymer zishonga mumazi ikozwe muri selile, igice cyingenzi cyimiterere yibimera. Hariho ubwoko butandukanye bwa selile ethers, buri kimwe gifite imiterere yihariye ituma biba byiza kubikorwa bitandukanye.
Ibyiciro bya tekinike ya selile ya selile ikoreshwa mubintu byose uhereye kumiti yimiti no kwisiga kugeza mubwubatsi no gukora imyenda. Mubyongeyeho, bikoreshwa nkibiryo byongera ibiryo hamwe nibyimbye mumarangi no gutwikira.
Ubwoko bwa selile
Ubwoko butatu bukunze kugaragara kuri ether ya selile ni hydroxypropylmethylcellulose (HPMC), methylhydroxyethylcellulose (MHEC).
Bitewe nuburyo bwinshi, HPMC nubwoko bukoreshwa cyane bwa selile ether. Iraboneka mubyiciro bitandukanye bifite uburemere butandukanye bwa molekuline, impamyabumenyi yo gusimbuza hamwe na viscosities. HPMC irashobora gukoreshwa mubisubizo bya acide na alkaline, bigatuma biba byiza mubikorwa byinshi.
MHEC isa na HPMC ariko ifite hydroxypropyl yo hasi. Ugereranije na HPMC, ubushyuhe bwa gelation ya MHEC mubusanzwe burenga 80 ° C, bitewe nibiri mumatsinda hamwe nuburyo bwo gukora. MHEC isanzwe ikoreshwa nkibyimbye, binder, emulsion stabilisateur cyangwa firime yahoze.
Ether ya selulose ifite byinshi ikoreshwa kubera imiterere yihariye. Bimwe mubisanzwe bikoreshwa muri selile ya selile harimo:
Inkoko: Ethers ya selile irashobora gukoreshwa nkibibyibushye kumavuta, amavuta, imiti ya peteroli, ibiryo, amavuta yo kwisiga, hamwe na farumasi.
Binders: Ethers ya selile irashobora gukoreshwa nka binders muri tablet cyangwa granules. Batezimbere compressibilité yifu mugihe bagikomeza ibintu byiza bitemba.
Imisemburo ya Emulsion: Ethers ya selile irashobora guhagarika emulisiyo ikumira coescence cyangwa flocculation yibitonyanga bitatanye. Ibi bituma biba byiza gukoreshwa muri polimeri ya emulsiya nka irangi rya latex cyangwa ibifatika.
Abakora firime: Ether ya selile irashobora gukoreshwa mugukora firime cyangwa gutwikira hejuru. Bakunze gukoreshwa mubikorwa byubwubatsi nka tile cyangwa wallpaper. Filime zakozwe muri selile ya selile isanzwe igaragara kandi yoroheje, hamwe nubushyuhe bwiza.
