Cov Qauv rau Kev Lag Luam Ethanol
Qhov tsos thiab ntxhiab tsw
Cov khoom yuav tsum ntshiab thiab pob tshab, tsis muaj cov khoom qias neeg uas pom tseeb. Nws yuav tsum tsis muaj ntxhiab tsw txawv txawv, tsis muaj ntxhiab tsw qab, lossis lwm yam ntxhiab tsw txawv txawv.
Cov Cim Qhia Txog Lub Cev thiab Tshuaj
Cov ntsiab lus ntawm Ethanol (C₂H₅OH, feem pua ​​ntawm pawg): ≥ 95.0% (qib zoo tshaj), ≥ 95.0% (qib ib), ≥ 93.0% (qib tsim nyog).
Qhov Ceev ntawm Ethanol (20°C, g/cm³): 0.789–0.791 (qib zoo tshaj), 0.789–0.792 (qib ib), 0.789–0.793 (qib tsim nyog).
Ethanol Cov dej ntsiab lus (feem pua): ≤ 0.5% (qib zoo tshaj), ≤ 0.5% (qib thawj), ≤ 1.0% (qib tsim nyog).
Ethanol Acidity (xam raws li acetic acid, g/L): ≤ 0.05 (qib zoo tshaj), ≤ 0.10 (qib thawj), ≤ 0.20 (qib tsim nyog).
Cov khoom tsis hloov pauv (feem pua ​​loj): ≤ 0.002% (qib siab), ≤ 0.002% (qib thawj), ≤ 0.005% (qib tsim nyog).
Ethanol Cov hlau hnyav (xam ua Pb, mg/L): ≤ 1 mg/L (qib siab), ≤ 1 mg/L (qib ib), ≤ 2 mg/L (qib tsim nyog).
Lub sijhawm sim tshuaj potassium permanganate (min): > 30 feeb (qib siab), ≥ 20 feeb (qib ib), ≥ 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 hauv ntau yam kev siv hauv kev lag luam. Cov lag luam sib txawv tuaj yeem tsim cov qauv tshwj xeeb thiab ntxaws ntxaws ntxiv raws li lawv cov kev xav tau.

Shandong Pulisi Chemical Co., Ltd. | Ethanol (Ethyl Alcohol)
Ethanol los ntawm Shandong Pulisi Chemical muaj cov yam ntxwv huv siab (95%, 96%, 99.9%), zoo ruaj khov, ISO9001 / SGS / BV tau ntawv pov thawj, thiab kev sib tw nqi ntau.
Nrog 20+ xyoo ntawm kev paub txog kev xa khoom tawm, cov chaw khaws khoom loj hauv chaw nres nkoj, kev xa khoom sai, thiab kev koom tes ntev nrog cov tuam txhab lag luam thoob ntiaj teb, peb muab cov kev daws teeb meem txhim khu kev qha rau cov neeg yuav khoom lag luam, tshuaj, thiab khoom noj khoom haus ethanol thoob ntiaj teb.
