Pour point depressant refers to chemicals that can reduce the freezing point of lubricating oil. It is generally a polymer organic compound. Many varieties of pour point depressant are the same as oil and gas development.
The varieties commonly used in lubricating oil are alkyl naphthalene, polymethacrylate, polya-olefin and so on.
Among them, polya-olefin (code T803) is a new light color pour point depressant developed in the 1970s.
Using soft wax cracking olefin as raw material, after proper refining, the polymerization was carried out in the presence of Ziegler-Natta catalyst, the molecular weight was adjusted with H2, and the catalyst was removed with esterification water after treatment.
Freezing point (freezing point) refers to the high temperature at which the liquid level does not move when the oil is cooled under specified conditions, expressed in ℃.
Same number of carbon atoms:
(1) n-alkane >
Aromatics with long side chains >
Naphthene & gt;
Isoalkanes.
(2) the diesel water content exceeds the standard, and the freezing point will also be significantly higher.
The determination of freezing point was carried out according to GB/T 510-1983 (1991) "Determination of freezing point of petroleum products".
Suitable for the determination of dark petroleum products and lubricating oil solidification point.
The SH113E1 automatic freezing point tester is based on the national standard GB/T510 "petroleum product freezing point determination method" according to the use of contemporary advanced technology, set mechanical, optical, electronic and computer technology in one, can automatically complete the freezing point test of petroleum products, the instrument uses photoelectric detection technology, glass tube automatic tilt method,
Imported compressor refrigeration system to ensure that the required depth of refrigeration.
