What is the moisture content stipulated in the new fuel oil standard?

October 22, 2020

Moisture: Years of experience with resistant fuels have shown that in many cases the acid value of the oil in operation is increased due to the hydrolysis of the oil, so the new oil standard is & LT;
600 mg/L.
The moisture standard of the operating oil is 1000 mg/L.
Moisture content: test according to GB/T 7600 method.
Water will not only lead to the hydrolytic degradation of phosphate ester resistant fuel, increase of acid value, cause the corrosion of system components, but also affect the lubrication characteristics of the oil.
If the water content of the phosphate anti-fuel exceeds the standard, the cause should be identified quickly and effective treatment measures should be taken.
SH103 trace moisture tester (produced by Shandong Shengtai Instrument Co., LTD.) adopts The principle of Karl F. Coulomb titration and adopts microcomputer automatic control. Compared with similar products at home and abroad, SH103 trace moisture tester has the advantages of high sensitivity, fast electrolysis speed, short balance time, accurate deduction of blank, accurate and reliable analysis results, etc.
