The physical and chemical properties of grease mainly refer to the appearance and consistency of the grease, the corrosion of metals and the compatibility with synthetic rubber.
Testing the appearance of the grease can make a preliminary distinction between various types of grease and preliminary judgement on the quality of the grease;
Testing the consistency of the grease can judge the softness and hardness of the grease, preliminary understanding of the ability of the anti-drying agent of the white grease to squeeze and shear, and can reflect the difficulty of the grease to flow under external forces;
The determination of the corrosiveness of grease is to examine whether the grease has a corrosive effect on the metal;
Determination of the compatibility and swelling of grease with synthetic rubber, the compatibility of rubber with rubber parts can be evaluated according to the changes in volume and hardness of synthetic rubber before and after the test;
By measuring the contact resistance value of the grease, the influence of the grease on the change in the contact resistance can be evaluated.
The analysis and evaluation methods are: visual inspection method of appearance evaluation, GB / T269 "Measurement Method for Grease and Petroleum Cone Penetration" Hecheng Special Grease, GB / T7326 "Grease Test Method for Copper Copper Sheet Grease", SH / T0331 "Grease Corrosion Test Method ", SH / T0429" Measurement of Compatibility of Grease and Synthetic Rubber "Fok Special Oil Method, SH / T0691" Method of Determining Swelling Property of Lubricants for Synthetic Rubber "and SH / T0596" Method of Determining Contact Resistance of Grease "
