Description
Technical field
The present invention relates to a kind of method of testing of oil property, especially for the method for test MARINE MEDIUM SPEED ENGINE OIL black mud dispersive property.
Background technology
Along with updating of engine technology, the installation of anti-buffing ring or the peace and quiet ring of piston, oil consumption reduces, and generally is low to moderate 0.2～0.4g/kWh, and the repairing cycle prolongs greatly.Recycling for a long time in the process of oil product; scurrying into crankcase because of fuel has strengthened the influence that oil product causes; the heavy fuel that uses of ship use intermediate speed engine particularly; has higher asphalt content; in use bituminous matter is difficult to dissolved and disperses; partly form black mud thereby caused the ship use intermediate speed machine to appear at crankcase, tappet etc., produce phenomenons such as greasy filth increases, also will influence the normal operation of engine when serious through regular meeting.Therefore, the oil product that requires to be used for the ship use intermediate speed engine must possess good high-temperature detergent-dispersant performance energy, and particularly the black mud dispersibility that fuel oil medium pitch matter is caused will be got well, and could prolong the drain period effectively.The method that in the process for preparation of oil product, does not also have at present mud dispersive property in the lab investigation oil product, black mud dispersive property in the oil formula adjuvant can only aboard ship carry out, the means that shortage is tested in the laboratory can not be evaluated the composition of adjuvant in the process for preparation and the adjustment of content.
By looking into new discovery, do not see both at home and abroad and adopt the evaluation report of crankcase test method detersive black mud dispersive property.
Summary of the invention
The object of the present invention is to provide a kind of method of testing of MARINE MEDIUM SPEED ENGINE OIL black mud dispersive property, be implemented in the black mud dispersive property of measuring oil product in the laboratory, method is simple, and test result and practical application situation are approaching.
