Txij li thaum pib, peb lub tuam txhab feem ntau suav tias cov khoom zoo yog lub neej ntawm lub tuam txhab, txhim kho cov thev naus laus zis tsim khoom tas li, txhim kho cov khoom zoo heev thiab txhim kho lub tuam txhab kev tswj hwm zoo heev, ua raws li tus qauv hauv tebchaws ISO 9001: 2000 rau kev txo nqi loj 99% 96% Purity CAS No. 64-17-5 Kev lag luam qib Anhydrous Ethanol rau tshuaj tua kab mob, Peb tsom mus rau kev tsim tus kheej lub npe thiab ua ke nrog ntau lub sijhawm paub dhau los thiab cov khoom siv zoo tshaj plaws. Peb cov khoom koj tsim nyog muaj.
Txij li thaum pib, peb lub tuam txhab feem ntau suav tias cov khoom zoo yog lub neej ntawm lub tuam txhab, txhim kho cov thev naus laus zis tsim khoom tas li, txhim kho cov khoom zoo heev thiab txhim kho lub tuam txhab kev tswj hwm zoo heev, ua raws li tus qauv hauv tebchaws ISO 9001: 2000 rau, Peb tau tsim kev sib raug zoo ntev, ruaj khov thiab zoo nrog ntau lub tuam txhab tsim khoom thiab cov khw muag khoom thoob ntiaj teb. Tam sim no, peb tau tos ntsoov rau kev koom tes ntau dua nrog cov neeg siv khoom txawv teb chaws raws li kev sib pab. Thov koj xav tiv tauj peb kom paub meej ntxiv.

Cov Qauv rau Kev Lag Luam Ethanol
Qhov tsos thiab ntxhiab tsw
Cov khoom yuav tsum meej thiab pob tshab tsis muaj qhov tsis huv uas pom tseeb; nws yuav tsum tsis muaj ntxhiab tsw txawv, tsis muaj ntxhiab tsw khaus, lossis lwm yam ntxhiab tsw txawv.
Cov Cim Qhia Txog Lub Cev Thiab Tshuaj
Cov Khoom Muaj Ethanol: Feem pua ​​ntawm ethanol (C₂H₅OH) yuav tsum yog ≥ 95.0% (rau qib siab), ≥ 95.0% (rau qib ib), thiab ≥ 93.0% (rau qib tsim nyog).
Qhov Ceev (ntawm 20°C, g/cm³): Qhov Ceev yog 0.789–0.791 (qib zoo tshaj), 0.789–0.792 (qib ib), thiab 0.789–0.793 (qib tsim nyog).
Cov dej noo: Feem pua ​​ntawm cov dej noo yuav tsum yog ≤ 0.5% (qib zoo tshaj), ≤ 0.5% (qib ib), thiab ≤ 1.0% (qib tsim nyog).
Qhov Acidity (xam ua acetic acid, g/L): Qhov Acidity yuav tsum yog ≤ 0.05 (qib zoo tshaj), ≤ 0.10 (qib ib), thiab ≤ 0.20 (qib tsim nyog).
Cov Khoom seem tsis hloov pauv: Feem pua ​​ntawm cov khoom seem tsis hloov pauv yuav tsum yog ≤ 0.002% (qib siab), ≤ 0.002% (qib ib), thiab ≤ 0.005% (qib tsim nyog).
Cov Hlau Hnyav (xam ua Pb, mg/L): Cov hlau hnyav yuav tsum yog ≤ 1 mg/L (qib zoo tshaj), ≤ 1 mg/L (qib ib), thiab ≤ 2 mg/L (qib tsim nyog).
Kev Ntsuas Potassium Permanganate (min): Lub sijhawm sim yuav tsum yog ≥ 30 feeb (qib siab), ≥ 20 feeb (qib ib), thiab ≥ 10 feeb (qib tsim nyog).
Cov qauv no ua kom ntseeg tau tias cov cawv ethanol hauv kev lag luam zoo thiab muaj kev nyab xeeb thaum siv rau hauv ntau qhov chaw lag luam sib txawv. Cov lag luam sib txawv kuj tseem yuav muab cov qauv ntxaws ntxaws ntxiv raws li lawv tus kheej xav tau.
