Leej twg yog cov chaw tsim khoom ntawm hydroxyethylcellulose?

Hydroxyethylcellulose (HEC) yog ib qho hluavtaws polymer uas siv rau hauv ntau yam kev lag luam rau ntau lub hom phiaj. Nws yog non-ionic, dej-soluble polymer uas yog muab los ntawm cellulose, thiab yog siv los ua ib tug thickening agent, emulsifier, stabilizer, thiab suspending agent.

HEC yog tsim los ntawm ntau lub tuam txhab, suav nrog Dow Chemical, BASF, Ashland, AkzoNobel, thiab Clariant. Dow Chemical yog ib lub tuam txhab loj tshaj plaws ntawm HEC, thiab tsim ntau hom HEC, suav nrog Dowfax thiab Natrosol hom. BASF tsim cov Cellosize hom HEC, thaum Ashland tsim Aqualon hom. AkzoNobel tsim cov Aqualon thiab Aquasol hom HEC, thiab Clariant tsim cov hom Mowiol.

Txhua lub tuam txhab tsim tawm ntau qib ntawm HEC, uas txawv ntawm qhov hnyav molecular, viscosity, thiab lwm yam khoom. Qhov hnyav molecular ntawm HEC tuaj yeem nyob ntawm 100,000 txog 1,000,000, thiab cov viscosity tuaj yeem nyob ntawm 1 txog 10,000 cps. Cov qib ntawm HEC tsim los ntawm txhua lub tuam txhab kuj sib txawv raws li lawv cov solubility, stability, thiab compatibility nrog rau lwm cov khoom xyaw.

Ntxiv rau cov tuam txhab loj ntawm HEC, kuj tseem muaj cov tuam txhab me me uas tsim HEC. Cov tuam txhab no suav nrog Lubrizol, thiabKima Tshuaj. Txhua lub tuam txhab tsim tawm ntau qib ntawm HEC, uas txawv ntawm lawv cov khoom.

Zuag qhia tag nrho, muaj ntau lub tuam txhab tsim HEC, thiab txhua lub tuam txhab tsim ntau hom HEC. Cov qib ntawm HEC tsim los ntawm txhua lub tuam txhab sib txawv raws li lawv qhov hnyav molecular, viscosity, solubility, stability, thiab compatibility nrog lwm cov khoom xyaw.
