Waa maxay etherka Cellulose?

Ethers-ka Cellulose waa qoys ka kooban polymers-ka biyaha-milmi kara ama biyaha-kala-saaran oo laga soo qaatay cellulose, polymer-ka dabiiciga ah ee laga helo gidaarada unugyada dhirta.Alaabooyinkaan waxaa lagu soo saaraa kiimiko ahaan wax ka beddelka kooxaha hydroxyl ee cellulose, taasoo keentay noocyo kala duwan oo ether cellulose ah oo leh sifooyin kala duwan.Ethers Cellulose waxay ka helaan isticmaalka ballaaran ee warshado kala duwan sababtoo ah isku darka gaarka ah ee guryaha, oo ay ku jiraan milanka biyaha, awoodda dhumucda, kartida filim samaynta, iyo xasiloonida.

Noocyada muhiimka ah ee ether-ka cellulose waxaa ka mid ah:

1. Methyl Cellulose (MC):
   • Methyl cellulose waxaa lagu helaa iyadoo lagu soo bandhigo kooxaha methyl kooxaha hydroxyl ee cellulose.Waxaa caadi ahaan loo isticmaalaa sidii wax dhumucdiyeed iyo jelling codsiyo kala duwan, oo ay ku jiraan cuntada, daawooyinka, iyo qalabka dhismaha.
2. Hydroxyethyl Cellulose (HEC):
   • Hydroxyethyl cellulose waxaa lagu soo saaraa iyadoo la soo bandhigayo kooxaha hydroxyethyl ee cellulose.Waxaa si weyn loogu isticmaalaa dhumuc ahaan, rheology wax ka beddelka, iyo xasilinta alaabada sida isqurxinta, alaabta daryeelka shakhsi ahaaneed, iyo dawooyinka.
3. Hydroxypropyl Methyl Cellulose (HPMC):
   • Hydroxypropyl methyl cellulose waa ether cellulose ah oo la beddelay, oo ka kooban labada hydroxypropyl iyo methyl.Waxaa loo isticmaalaa qalabka dhismaha, daawooyinka, alaabta cuntada, iyo codsiyada warshadaha kala duwan ee ay dhumucdiisuna, haynta biyaha, iyo guryaha-samaynta filimada.
4. Ethyl Cellulose (EC):
   • Ethyl cellulose waxaa lagu soo bandhigaa kooxaha ethyl ee cellulose.Waxaa lagu yaqaanaa dabeecadeeda biyaha-aan-milmi karin waxaana caadi ahaan loo isticmaalaa sidii wakiilka filim-samaynta, gaar ahaan warshadaha dawooyinka iyo dahaadhka.
5. Carboxymethyl Cellulose (CMC):
   • Carboxymethyl cellulose waxaa lagu helaa iyadoo lagu soo bandhigo kooxaha karboxymethyl ee cellulose.Waxaa si weyn loogu isticmaalaa sida wakiilka dhumuc, xasiliye, iyo wakiilka biyaha haynta ee alaabta cuntada, daawooyinka, iyo codsiyada warshadaha.
6. Hydroxypropyl Cellulose (HPC):
   • Hydroxypropyl cellulose waxaa lagu soo saaraa iyadoo lagu soo bandhigo kooxaha hydroxypropyl ee cellulose.Waxaa caadi ahaan loo isticmaalaa warshadaha dawooyinka sida xidhe, wakiilka filim samaynta, iyo dhumucyada qaabaynta kiniinka.

Ether-ka Cellulose waxaa lagu qiimeeyaa awooda ay u leeyihiin inay wax ka bedelaan sifooyinka rheological iyo farsamada ee qaababka kala duwan.Codsigoodu wuxuu gaarayaa warshado kala duwan, oo ay ku jiraan:

• Dhisidda: Hoobiyeyaasha, xabagta, iyo dahaarka si kor loogu qaado haynta biyaha, shaqaynta, iyo ku dhegsiga
• Daawooyinka: Dahaarka kiniinka, xidhayaasha, iyo qaabaynta sii-daynta joogtada ah.
• Cuntada iyo Cabbitaannada: Kuwa dhumucsada, xasiliyayaal, iyo kuwa beddesha baruurta.
• Waxyaabaha la isku qurxiyo iyo Daryeelka Shakhsi ahaaneed: Kareemada, labeennada, shaambooyinka, iyo alaabada kale ee dhumucdooda iyo xasilinta.

Nooca gaarka ah ee eter cellulose ee la doortay waxay kuxirantahay sifooyinka la rabo codsi gaar ah.Kala-duwanaanta ethers-ka cellulose waxay ka dhigtaa kuwo qiimo leh oo kala duwan oo badeecado ah, oo gacan ka geysanaya hagaajinta tayada, xasiloonida, iyo waxqabadka.
