Noocyada etherka cellulose
Ethers Cellulose waa koox kala duwan oo ka-soo-baxa ah oo la helay iyadoo kiimiko ahaan wax looga beddelayo cellulose dabiiciga ah, oo ah qaybta ugu muhiimsan ee derbiyada unugyada dhirta. Nooca gaarka ah ee ether-ka cellulose waxaa lagu go'aamiyaa dabeecadda wax ka beddelka kiimikaad ee lagu soo bandhigay laf dhabarta cellulose. Waa kuwan qaar ka mid ah noocyada caadiga ah ee ether-ka cellulose, mid kastaa wuxuu leeyahay sifooyin gaar ah iyo codsiyo:
- Methyl Cellulose (MC):
- Beddelka Kiimikada: Horudhaca kooxaha methyl ee lafta dhabarka cellulose.
- Guryaha iyo Codsiyada:
- Biyo-milmi kara.
- Loo isticmaalo agabka dhismaha (hoobiyeyaasha, xabagta), alaabta cuntada, iyo dawooyinka (dahaadhka kiniinka).
- Hydroxyethyl Cellulose (HEC):
- Beddelka Kiimikada: Horudhaca kooxaha hydroxyethyl ee lafta dhabarka cellulose.
- Guryaha iyo Codsiyada:
- Biyo aad u sarreeya.
- Caadi ahaan loo isticmaalo waxyaabaha la isku qurxiyo, alaabta daryeelka shakhsi ahaaneed, rinjiga, iyo daawooyinka.
- Hydroxypropyl Methyl Cellulose (HPMC):
- Beddelka Kiimikada: Horudhaca kooxaha hydroxypropyl iyo methyl ee lafta dhabarka cellulose.
- Guryaha iyo Codsiyada:
- Biyo-milmi kara.
- Si ballaaran loo isticmaalo agabka dhismaha (hoobiye, dahaarka), daawooyinka, iyo alaabta cuntada.
- Carboxymethyl Cellulose (CMC):
- Beddelka Kiimikada: Horudhaca kooxaha karboksymethyl ee lafta dhabarka cellulose.
- Guryaha iyo Codsiyada:
- Biyo-milmi kara.
- Loo isticmaalo sidii dhumuc iyo dejiye ahaan badeecadaha cuntada, dawooyinka, dunta, iyo dareeraha qodista.
- Hydroxypropyl Cellulose (HPC):
- Beddelka Kiimikada: Horudhaca kooxaha hydroxypropyl ee lafta dhabarka cellulose.
- Guryaha iyo Codsiyada:
- Biyo-milmi kara.
- Caadi ahaan loo isticmaalo dawooyinka sida binder, wakiilka filim samaynta, iyo dhumuclaha.
- Ethyl Cellulose (EC):
- Beddelka Kiimikada: Horudhaca kooxaha ethyl ee lafta dhabarka cellulose.
- Guryaha iyo Codsiyada:
- Biyo-ma-milmi kara.
- Loo isticmaalo dahaarka, filimada, iyo hababka dawooyinka la sii daayo ee la xakameeyey.
- Hydroxyethyl Methyl Cellulose (HEMC):
- Beddelka Kiimikada: Horudhaca kooxaha hydroxyethyl iyo methyl ee lafta dhabarka cellulose.
- Guryaha iyo Codsiyada:
- Biyo-milmi kara.
- Caadi ahaan loo isticmaalo qalabka dhismaha (hoobiye, grouts), rinji, iyo waxyaalaha la isku qurxiyo.
Noocyadan ether-ka cellulose waxaa lagu doortaa iyadoo lagu saleynayo hantidooda gaarka ah iyo shaqeyntooda looga baahan yahay codsiyo kala duwan. Wax ka beddelka kiimikooyinka ayaa go'aamiya milanka, viscosity, iyo sifooyinka waxqabadka kale ee ether kasta oo cellulose, iyaga oo ka dhigaya wax lagu daro warshadaha sida dhismaha, daawooyinka, cuntada, qurxinta, iyo in ka badan.
