Automatic measuring solution for freezing point of pour point depressant
Pour point depressant refers to the chemical can reduce the freezing point of lubricating oil, generally is a polymer organic compound, many varieties and oil and gas using pour point depressant. Lubricating oil commonly used varieties are alkyl naphthalene, poly methacrylate, poly A - olefin. Among them, polya-olefin (code name T803) is a new light color pour point depressant developed in 1970. The olefin of soft wax cracking was used as raw material, after being properly refined, it was polymerized in the presence of Ziegler-Natta catalyst, the molecular weight was adjusted by H2, and the catalyst was removed by esterification water after treatment.
Freezing point (freezing point) refers to the oil under specified conditions, cooling to the liquid level does not move when the high temperature, expressed in ℃. Have the same number of carbon atoms:
(1) N-alkanes & GT; Aromatics with long side chains & GT; Naphthene & gt; Isomeric alkanes.
(2) Diesel oil water content exceeds the standard, freezing point will be significantly higher.
The freezing point is determined according to GB/T 510-1983 (1991) "Petroleum Products freezing point Determination Method". Suitable for measuring freezing point of dark petroleum products and lubricating oil. And SH113E1 automatic freezing point tester is based on the national standard GB/T510 "petroleum products freezing point determination method", the use of modern advanced technology, set of mechanical, optical, electronic and computer technology in one, can automatically complete the freezing point test of petroleum products, this instrument uses photoelectric detection technology, glass tube automatic tilt method, Imported compressor refrigeration system to ensure the required refrigeration depth.
