Ubani umkhiqizi we-hydroxyethylcellulose?

IHydroxyethylcellulose (HEC) iyi-polymer yokwenziwa esetshenziswa ezimbonini ezahlukahlukene ngezinhloso ezahlukahlukene. Kuyi-polymer engeyona i-ionic, encibilika emanzini etholakala ku-cellulose, futhi isetshenziswa njenge-ejenti yokuqina, i-emulsifier, i-stabilizer, ne-ejenti elengayo.

I-HEC ikhiqizwa izinkampani ezihlukahlukene, okuhlanganisa i-Dow Chemical, i-BASF, i-Ashland, i-AkzoNobel, ne-Clariant. I-Dow Chemical ingomunye wabakhiqizi abakhulu be-HEC, futhi ikhiqiza amamaki ahlukahlukene e-HEC, okuhlanganisa ne-Dowfax ne-Natrosol brand. I-BASF ikhiqiza uhlobo lwe-Cellosize lwe-HEC, kanti i-Ashland ikhiqiza uhlobo lwe-Aqualon. I-AkzoNobel ikhiqiza uhlobo lwe-Aqualon ne-Aquasol ye-HEC, kanti i-Clariant ikhiqiza uhlobo lwe-Mowiol.

Ngayinye yalezi zinkampani ikhiqiza amamaki ahlukahlukene we-HEC, ahluke ngokwesisindo samangqamuzana, i-viscosity, nezinye izakhiwo. Isisindo samangqamuzana e-HEC singasuka ku-100,000 siye ku-1,000,000, futhi i-viscosity ingaba kusuka ku-1 kuya ku-10,000 cps. Amabanga e-HEC akhiqizwa yinkampani ngayinye nawo ayahluka ngokuya ngokuncibilika kwawo, ukuzinza, nokuhambisana nezinye izithako.

Ngaphezu kwabakhiqizi abakhulu be-HEC, kukhona nenani lezinkampani ezincane ezikhiqiza i-HEC. Lezi zinkampani zifaka i-Lubrizol, kanyeI-Kima Chemical. Ngayinye yalezi zinkampani ikhiqiza amamaki ahlukahlukene e-HEC, ahluka ngokwezakhiwo zawo.

Sekukonke, kunezinhlobonhlobo zezinkampani ezikhiqiza i-HEC, futhi inkampani ngayinye ikhiqiza amamaki ahlukahlukene we-HEC. Amabanga e-HEC akhiqizwa yinkampani ngayinye ayahluka ngokwesisindo samangqamuzana, i-viscosity, ukuncibilika, ukuzinza, nokuhambisana nezinye izithako.
