A:Product Introduction:
DSHD-3554 Petroleum Wax Oil Content Tester is designed and made as per the National Standard of People's Republic
of China GB/T3554"Test Methods for Oil Content of Petroleum Wax".
DSHD-3554 Petroleum Wax Oil Content Testeris suitable to determine the oil content of petroleum wax, the congealing point of which is higher than 30°C and the oil content of which is not more than 15%.
Specific operation is as follows: Solve sample in the methyl ethyl ketone and cool it to -32°C to separate wax out. Filter it and evaporate methyl
ethyl ketone in the filtering liquid. Weigh the residue and calculate the oil content in the wax.
DSHD-3554 Petroleum Wax Oil Content Tester is worth noting that For some wax having oil content
higher than 5%, if the oil could not be completed dissolved in the methyl ethyl ketone, please don't use
this instrument.
