Ngubani umenzi we-hydroxyethylcellulose?

IHydroxyethylcellulose (HEC) yipolymer eyenziweyo esetyenziswa kumashishini ahlukeneyo ngeenjongo ezahlukeneyo.I-non-ionic, i-polymer e-soluble yamanzi ephuma kwi-cellulose, kwaye isetyenziswe njenge-agent agent, i-emulsifier, i-stabilizer, kunye ne-arhente yokumisa.

I-HEC yenziwa ziinkampani ezahlukeneyo, kubandakanya iDow Chemical, BASF, Ashland, AkzoNobel, kunye neClariant.I-Dow Chemical ingomnye wabenzi abakhulu be-HEC, kwaye ivelisa iindidi ezahlukeneyo ze-HEC, kuquka i-Dowfax kunye ne-Natrosol brand.I-BASF ivelisa uphawu lwe-Cellosize lwe-HEC, ngelixa i-Ashland ivelisa uphawu lwe-Aqualon.I-AkzoNobel ivelisa i-Aqualon kunye ne-Aquasol brand ye-HEC, kwaye i-Clariant ivelisa i-brand ye-Mowiol.

Nganye kwezi nkampani zivelisa iindidi ezahlukeneyo ze-HEC, ezihluke ngokwemilinganiselo ye-molecular weight, viscosity, kunye nezinye iipropati.Ubunzima be-molecular HEC bunokuvela kwi-100,000 ukuya kwi-1,000,000, kwaye i-viscosity inokuvela kwi-1 ukuya kwi-10,000 cps.Amabakala e-HEC aveliswe yinkampani nganye nawo ayahluka ngokwemiqathango yokunyibilika kwawo, ukuzinza, kunye nokuhambelana nezinye izithako.

Ukongeza kubavelisi abakhulu be-HEC, kukho nenani leenkampani ezincinci ezivelisa i-HEC.Ezi nkampani ziquka iLubrizol, kunyeKima Chemical.Nganye kwezi nkampani zivelisa iindidi ezahlukeneyo ze-HEC, ezahlukileyo ngokweempawu zazo.

Ngokubanzi, kukho iindidi zeenkampani ezivelisa i-HEC, kwaye inkampani nganye ivelisa iindidi ezahlukeneyo ze-HEC.Amabakala e-HEC aveliswe yinkampani nganye ayahluka ngokobunzima bemolekyuli, i-viscosity, i-solubility, ukuzinza, kunye nokuhambelana nezinye izithako.
