Qaab-dhismeedka Kiimikada iyo Soo-saareha Eter-ka Cellulose
Eter-ka cellulosewaa qoys ka mid ah polymers-ka biyaha ku milma oo ka soo jeeda cellulose, polymer dabiici ah oo laga helo gidaarada unugyada dhirta. Qaab dhismeedka kiimikada ee ethers cellulose waxaa lagu gaaraa iyada oo loo marayo isbeddelka kiimikaad ee cellulose iyada oo la soo bandhigayo kooxo kala duwan oo ether ah. Ether-yada cellulose-ka caadiga ah waxaa ka mid ah Hydroxyethyl Cellulose (HEC), Hydroxypropyl Methylcellulose (HPMC), Methyl Cellulose (MC), Carboxymethyl Cellulose (CMC), iyo kuwo kale. Qaab dhismeedka kiimikada ee ethers cellulose waa sida soo socota:
- Hydroxyethyl Cellulose (HEC):
- Kooxaha Hydroxyethyl waxaa lagu soo bandhigaa qaab-dhismeedka cellulose.
- Qaab dhismeedka Kiimikada: [Cellulose] - [O-CH2-CH2-OH]
- Hydroxypropyl Methylcellulose (HPMC):
- Hydroxypropyl iyo kooxaha methyl waxaa lagu soo bandhigaa qaab-dhismeedka cellulose.
- Qaabdhismeedka Kiimikada: [Cellulose] - [O-CH2-CHOH-CH3] iyo [O-CH3]
- Methyl Cellulose (MC):
- Kooxaha Methyl waxaa lagu soo bandhigaa qaab-dhismeedka cellulose.
- Qaab dhismeedka Kiimikada: [Cellulose] - [O-CH3]
- Carboxymethyl Cellulose (CMC):
- Kooxaha Carboxymethyl waxaa lagu soo bandhigaa qaab dhismeedka cellulose.
- Qaab dhismeedka Kiimikada: [Cellulose] - [O-CH2-COOH]
Qaab dhismeedka kiimikada saxda ah wuu kala duwanaan karaa iyadoo ku saleysan heerka beddelka (DS) iyo arrimo kale oo la xiriira habka wax soo saarka. Soo bandhigida kooxahan ether-ka ayaa siinaya sifooyin gaar ah ether kasta oo cellulose ah, sida milanka biyaha, awoodda dhumucda, kartida samaynta filimada, iyo in ka badan.
Soo-saareyaasha ether-ka cellulose waxaa ka mid ah shirkado caalami ah iyo kuwo heer gobol ah. Qaar ka mid ah soosaarayaasha caanka ah ee warshadaha ethers cellulose waxaa ka mid ah:
- Kiimikada Kima:
- Kima Chemical waa shirkad kiimiko ah oo eter cellulose ah oo caalami ah oo soo saarta alaabooyin kiimiko oo kala duwan, oo ay ku jiraan ether-ka cellulose.
- Shin-Etsu:
- Shin-Etsu, oo fadhigeedu yahay Japan, ayaa caan ku ah soo saarista alaabada kiimikaad ee kala duwan, oo ay ku jiraan kuwa laga soo saaro cellulose.
- Ashland Inc.
- Ashland waa shirkad caalami ah oo kiimikooyinka takhasuska leh oo soo saarta ethers cellulose ka mid ah alaabada kale.
- CP Kelco:
- CP Kelco waa soo saaraha caalamiga ah ee hormuudka ka ah hydrocolloids takhasuska leh, oo ay ku jiraan ethers cellulose.
- AkzoNobel:
- AkzoNobel waa shirkad caalami ah oo soo saarta kiimikooyin gaar ah oo kala duwan, oo ay ku jiraan ethers cellulose.
- Nouryon (oo hore u ahaan jiray AkzoNobel Kiimikooyinka Takhasuska leh):
- Nuryon waa soo saaraha ugu weyn ee kiimikooyinka gaarka ah, waxayna sii waddaa dhaxalka kiimikooyinka gaarka ah ee AkzoNobel.
Shirkadahani waxay si weyn uga dhex muuqdaan suuqa ethers-ka cellulose waxayna bixiyaan darajooyin kala duwan iyo kala duwanaansho si ay u daboolaan baahiyaha warshadeed iyo kuwa ganacsi ee kala duwan. Marka la isticmaalayo cellulose ethers, waxaa muhiim ah in la tixraaco dukumentiga alaabta gaarka ah ee uu bixiyo soo saaraha si aad u hesho macluumaad faahfaahsan oo ku saabsan guryaha, heerarka isticmaalka ee lagu taliyay, iyo faahfaahin kale oo farsamo.
