Eter-ka cellulose

Cellulose ethers waa qoys ka kooban polysaccharides kuwaas oo ka soo jeeda cellulose, polymer-ka ugu badan ee dabiiciga ah ee dhulka. Waa kuwo biyaha lagu milma waxayna leeyihiin codsiyo kala duwan oo kala duwan oo laga helo warshadaha kala duwan, oo ay ku jiraan cuntada, daawooyinka, qurxinta, iyo dhismaha. Maqaalkan, waxaan ka wada hadli doonaa sifooyinka, wax soo saarka, iyo codsiyada ethers cellulose si faahfaahsan.

Guryaha Ethers Cellulose

Ether-yada Cellulose waxay leeyihiin waxyaabo isku dhafan oo gaar ah oo ka dhigaya kuwo aad waxtar u leh codsiyada kala duwan. Qaar ka mid ah sifooyinka muhiimka ah ee ethers cellulose waxaa ka mid ah:

Biyo Solubility: Ether-ka Cellulose waa kuwo aad u biyo-milmi kara, taas oo u sahlaysa in loo isticmaalo hababka aqueous. Hantidani waxay sidoo kale ka dhigtaa dhumucyada iyo xasiliyeyaasha waxtarka leh ee cuntada iyo qaababka daawooyinka.

Guryaha Samaynta Filimada: Ether-yada Cellulose waxay samayn karaan filimo cad, dabacsan, iyo xoog leh marka ay ku milmaan biyaha. Hantidani waxay faa'iido u leedahay soo saarista dahaarka, dhejiska, iyo filimada.

Degganaanshaha Kiimikada: Ether-ka Cellulose waa kiimiko ahaan deggan oo adkaysi u leh xaalufka microbial, taas oo ka dhigaysa inay ku habboon yihiin isticmaalka codsiyada warshadaha kala duwan.

Sunta Aan ahayn: Ether-ka Cellulose waa kuwo aan sun ahayn oo badbaado u leh isticmaalka cuntada, daawooyinka, iyo alaabta daryeelka shakhsi ahaaneed.

Wax soo saarka Ethers Cellulose

Ether-ka Cellulose waxaa lagu soo saaraa iyadoo wax laga beddelayo cellulose iyada oo loo marayo falcelin kiimikaad oo leh kooxo kala duwan oo shaqeynaya. Noocyada ugu caansan ee ether-ka cellulose waxaa ka mid ah:

Methylcellulose (MC): Methylcellulose waxaa lagu soo saaraa iyada oo ka falcelinaysa cellulose leh methyl chloride iyo sodium hydroxide. Waxaa si weyn loogu isticmaalaa sidii dhumuc iyo xasiliye ahaan cuntada iyo qaababka daawooyinka.

Hydroxypropyl Cellulose (HPC): Hydroxypropyl cellulose waxa lagu soo saaraa iyada oo ka falcelinaysa cellulose leh propylene oxide iyo hydrochloric acid. Waxa loo istcimaalaa sida xidhe, emulsifier, iyo dhumucweyn xagga cuntada, daawooyinka, iyo alaabta daryeelka shakhsi ahaaneed.

Ethylcellulose (EC): Ethylcellulose waxaa lagu soo saaraa iyada oo ka falcelinaysa cellulose leh ethyl chloride iyo sodium hydroxide. Waxaa loo istcimaalaa sidii binder, filim-hore, iyo wakiilka dahaarka ee warshadaha daryeelka dawooyinka iyo kuwa gaarka ah.

Carboxymethyl Cellulose (CMC): Carboxymethyl cellulose waxa lagu soo saaraa iyada oo ka falcelinaysa cellulose leh chloroacetic acid iyo sodium hydroxide. Waxa loo isticmaalaa sidii dhumuc, xasiliye, iyo emulsifier gudaha cuntada, dawooyinka, iyo warshadaha daryeelka shakhsi ahaaneed.

Hydroxyethyl Cellulose (HEC): Hydroxyethyl cellulose waxaa lagu soo saaraa iyada oo ka falcelinaysa cellulose leh ethylene oxide iyo sodium hydroxide. Waxa loo isticmaalaa sidii dhumuc, xasiliye, iyo emulsifier gudaha cuntada, dawooyinka, iyo warshadaha daryeelka shakhsi ahaaneed.

Codsiyada Ethers Cellulose

Ether-yada Cellulose waxay leeyihiin codsiyo kala duwan oo kala duwan oo laga helo warshadaha kala duwan, oo ay ku jiraan:

Warshadaha Cuntada: Ether-ka Cellulose waxaa si weyn loogu isticmaalaa dhumucyada, xasiliyayaal, iyo emulsifiers ee habaynta cuntada. Waxaa loo isticmaalaa alaabada sida jalaatada, suugada, dhaymada, iyo alaabta la dubay.

Warshadaha Dawaynta: Ether-ka Cellulose waxa loo isticmaalaa xidhiyaal ahaan, kala daadsanaan, iyo dahaar ka samaysan hababka dawooyinka. Waxaa loo isticmaalaa kiniinno, kaabsal, iyo qaabab kale oo adag.

Warshadaha Daryeelka Shakhsi ahaaneed: Ether-ka Cellulose waxa loo isticmaalaa dhumucyada, xasiliyayaal, iyo emulsifiers ee alaabta daryeelka shakhsi ahaaneed sida shaambada, kiriimyada, iyo kiriimyada.

Warshadaha Dhismaha: Ether-ka Cellulose waxa loo isticmaalaa sida wakiilada biyaha haynta, dhumucyada, iyo xidhayaasha qalabka dhismaha sida sibidhka, hoobiye.
