Waa maxay Ethers Cellulose iyo sababta loo isticmaalo?

Ethers-ka Cellulose waa polymers-biyo-milmi leh oo laga sameeyay cellulose, oo ah qaybta ugu muhiimsan ee dhismaha dhirta. Waxaa jira dhowr nooc oo ethers cellulose ah, mid kasta oo leh sifooyin gaar ah oo ka dhigaya kuwo ku habboon codsiyada kala duwan.

Darajooyinka farsamada ee ether-ka cellulose waxaa loo isticmaalaa wax kasta laga bilaabo dawooyinka iyo waxyaalaha la isku qurxiyo ilaa dhismaha iyo wax soo saarka dharka. Intaa waxaa dheer, waxaa loo isticmaalaa sida cuntada lagu daro iyo dhumucyada rinjiga iyo dahaarka.

Noocyada ethers cellulose

Saddexda nooc ee ugu caansan ethers-ka cellulose waa hydroxypropylmethylcellulose (HPMC), methylhydroxyethylcellulose (MHEC).

Kala duwanaanshaheeda awgeed, HPMC waa nooca ugu badan ee loo isticmaalo ether-ka cellulose. Waxaa lagu heli karaa darajooyin kala duwan oo leh miisaanyo unugyo kala duwan, darajo beddelka iyo viscosities. HPMC waxaa loo isticmaali karaa xalalka acidic iyo alkaline labadaba, taasoo ka dhigaysa mid ku habboon codsiyo kala duwan.

MHEC waxay la mid tahay HPMC laakiin waxay leedahay wax ka kooban hydroxypropyl hoose. Marka la barbar dhigo HPMC, heerkulka gelation ee MHEC inta badan waa ka sarreeyaa 80 ° C, taas oo ku xidhan waxa kooxda iyo habka wax soo saarka. MHEC waxaa caadi ahaan loo isticmaalaa sida dhumuclaha, binder, emulsion stabilizer ama filim hore.

Ether-ka Cellulose waxay leeyihiin adeegsi badan sababtoo ah sifooyinkooda gaarka ah. Qaar ka mid ah isticmaalka caadiga ah ee ether-ka cellulose waxaa ka mid ah:

Dhumucyada: Ether-ka Cellulose waxa loo isticmaali karaa dhumucyo ahaan saliidaha, xabagta, kiimikooyinka goobta saliidda, cuntada, waxyaalaha la isku qurxiyo, iyo dawooyinka.

Xirayaasha: Ether-ka Cellulose waxa loo isticmaali karaa sida xidheyaasha kiniinka ama granules. Waxay hagaajiyaan isku-buufinta budada iyagoo wali ilaalinaya sifooyinka socodka wanaagsan.

Emulsion Stabilizers: Ethers Cellulose waxay xasilin karaan emulsions iyaga oo ka hortagaya isku-dhafka ama qulqulka dhibcaha wajiga kala firdhiyey. Tani waxay ka dhigeysaa mid ku habboon in loo isticmaalo polymers-ka emulsion sida rinjiyada cinjirka ama koollada.

Filimkii hore: ether-ka Cellulose waxa loo isticmaali karaa in lagu sameeyo filimo ama dahaaryo dusha sare ah. Inta badan waxaa loo isticmaalaa codsiyada dhismaha sida xabagta ama dhejiska gidaarka. Filimada laga sameeyay ether-ka cellulose sida caadiga ah waa kuwo hufan oo dabacsan, oo leh caabbinta qoyaanka wanaagsan.
