Waa maxay noocyada ether cellulose?

Ethers Cellulose waa koox kala duwan oo polymers ah oo ka soo jeeda cellulose, polysaccharide dabiiciga ah oo laga helo dhirta.Waxaa si aad ah looga isticmaalaa warshado kala duwan, oo ay ku jiraan dhismaha, daawooyinka, cuntada, qurxinta, iyo daryeelka shakhsi ahaaneed, sababtoo ah hantidooda gaarka ah iyo wax-qabadkooda.Waa kuwan qaar ka mid ah noocyada ugu caansan ee ether cellulose:

1. Methyl Cellulose (MC):
   • Methyl cellulose waxaa lagu soo saaraa iyadoo lagu daaweynayo cellulose leh methyl chloride si loogu soo bandhigo kooxaha methyl lafta dhabarka cellulose.
   • Waxay ku milmaysaa biyo qabow waxayna samaysaa xalal cad oo muuqda.
   • MC waxa loo isticmaalaa dhumuc weyn, xidhe, iyo xasiliye codsiyo balaadhan oo kala duwan, oo ay ku jiraan agabka dhismaha (tusaale, hoobiye-cement-ku-salaysan, balastarrada gypsum-ku-salaysan), badeecooyinka cuntada, dawooyinka, iyo alaabta daryeelka shakhsi ahaaneed.
2. Hydroxyethyl Cellulose (HEC):
   • Hydroxyethyl cellulose waxa lagu farsameeyaa iyada oo ka falcelinaysa cellulose leh ethylene oxide si ay u soo bandhigto kooxaha hydroxyethyl ee laf dhabarta cellulose.
   • Waxay ku milmi kartaa biyo qabow waxayna samaysaa xalal cad oo muuqda oo leh sifooyin biyo celin ah oo aad u fiican.
   • HEC waxaa caadi ahaan loo isticmaalaa sidii dhumuc, beddele rheology, iyo wakiilka samaynta filimada ee rinjiga, xabagta, alaabta daryeelka shakhsi ahaaneed, iyo daawooyinka.
3. Hydroxypropyl Methyl Cellulose (HPMC):
   • Hydroxypropyl methyl cellulose waxa lagu soo saaraa iyada oo la soo bandhigayo hydroxypropyl iyo methyl kooxaha laf dhabarta cellulose.
   • Waxay soo bandhigaysaa sifooyin la mid ah methyl cellulose iyo hydroxyethyl cellulose labadaba, oo ay ku jiraan milanka biyaha, kartida samaynta filimada, iyo xajinta biyaha.
   • HPMC waxa si weyn loogu isticmaalaa agabka dhismaha (tusaale, xabag-xabagta, wax-soo-saarka sibidhka ku salaysan, iskudhisyada is-beddelka), iyo sidoo kale daawooyinka, alaabta cuntada, iyo alaabta daryeelka shakhsi ahaaneed.
4. Carboxymethyl Cellulose (CMC):
   • Carboxymethyl cellulose waxaa laga soo qaatay cellulose iyadoo lagu daaweeyay sodium hydroxide iyo monochloroacetic acid si loo soo bandhigo kooxaha karboxymethyl.
   • Waxay ku milmi kartaa biyaha waxayna samaysaa xalal cad oo viscous leh oo leh dhumuc aad u wanaagsan, xasilin, iyo sifooyin biyo celin ah.
   • CMC waxa caadi ahaan loo isticmaalaa dhumucdiye, xidhe, iyo rheology wax ka beddelka alaabta cuntada, dawooyinka, dunta, waraaqaha, iyo qalabka dhismaha qaarkood.
5. Ethyl Cellulose (EC):
   • Ethyl cellulose waxaa la soo saaraa iyada oo ka falcelinaysa cellulose leh ethyl chloride si ay u soo bandhigto kooxaha ethyl ee laf dhabarta cellulose.
   • Waa mid aan lagu milmi karin biyaha laakiin waxay ku milmi kartaa dareeraha organic sida ethanol iyo chloroform.
   • EC waxaa caadi ahaan loo isticmaalaa sidii wakiilka filim samaynta, xidhidhka, iyo walxaha dahaarka ee daawooyinka, alaabta cuntada, waxyaalaha la isku qurxiyo, iyo codsiyada warshadaha.

Kuwani waa qaar ka mid ah noocyada ugu badan ee loo isticmaalo ether cellulose, mid kastaa wuxuu bixiyaa sifooyin gaar ah iyo faa'iidooyin codsiyada kala duwan.Ethers kale oo khaas ah ayaa laga yaabaa inay jiraan, oo ku habboon shuruudaha gaarka ah ee warshadaha kala duwan.
