Ethylene glycol (EG), tseem hu ua mono ethylene glycol (MEG), yog dav siv nyob rau hauv antifreeze, coolants, heat-hloov kua, polyester fiber, PET ntau lawm, thiab tshuaj manufacturing. Rau cov neeg yuav khoom, qhov sib txawv ntawm 99%, 99.5%, thiab 99.9% ethylene glycol tsis yog txiav txim los ntawm kev soj ntsuam ib leeg. Dej, diethylene glycol (DEG), aldehydes, hlau, acidity, xim, thiab lwm yam impurities kuj muaj feem xyuam rau seb EG cov khoom ua tau raws li ib daim ntawv thov lossis tus qauv.
Yam twg Ethylene Glycol Purity Koj Yuav Tsum Yuav?
Rau feem ntau cov ntawv thov kev lag luam, 99% ethylene glycol tej zaum yuav txaus, thaum polyester thiab PET ntau lawm feem ntau xav tau siab dua -purity EG nrog nruj impurity txwv.
99% ethylene glycol: Feem ntau siv los tiv thaiv khov, ua kom txias, cua sov- hloov cov kua dej, thiab cov ntawv thov kev lag luam.
99.5% ethylene glycol: Haum rau cov ntawv thov uas xav tau kev soj ntsuam siab dua, tab sis tus nqi 99.5% ib leeg tsis txhais cov qib kev lag luam tshwj xeeb.
99.9% ethylene glycol: Feem ntau siv rau qhov yuav tsum tau tswj nruj dua ntawm impurities, suav nrog polyester thiab PET ntau lawm.
Rau kev yuav khoom ntau, cov neeg yuav khoom yuav tsum sib piv cov ethylene glycol specification thiab COA, tsis yog xaiv ib yam khoom los ntawm nws cov purity tshaj tawm.
99% vs 99.5% vs 99.9% Ethylene Glycol
Qhov sib txawv tseem ceeb ntawm 99%, 99.5%, thiab 99.9% ethylene glycol yog qhov xav tau ntawm EG kev soj ntsuam thiab, nyob ntawm qib, kev tswj nruj dua ntawm impurities.
