Problems solved by technology

[0005] However, these various manganese phosphate crystal nuclei used as surface modifiers have disadvantages, that is, the particle size of manganese phosphate is too large, and it is easy to agglomerate over time, and its shape is powder, which is inconvenient to use.

preparation example Construction

[0031] The preparation method of the dispersion is as follows: there is no special limitation on the preparation method for dispersing the manganese phosphate in the aqueous medium to form the aqueous dispersion. A better method is to mix the manganese phosphate in the dispersion medium such as water or organic solvent, and then Prepared by wet pulverization in the presence of additives.

[0032]When preparing an aqueous dispersion of manganese phosphate, it is more appropriate in the process to mix manganese phosphate in an aqueous medium for wet pulverization when preparing the dispersion, or wet grinding in a dispersion medium other than the aqueous medium. After pulverization, solvent replacement was performed again to prepare a solution.

[0033] Usually, the blending amount of manganese phosphate in the dispersion is 0.5 to 50%. If it is less than 0.5%, the content of manganese phosphate is too small, and the effect of the surface conditioner obtained with this dispersio...

Abstract

The invention provides a surface adjusting agent containing manganese phosphate. The surface adjusting agent containing the manganese phosphate comprises the following components of, by weight, 0.4-5parts of the manganese phosphate, 80-100 parts of a solvent, 2-10 parts of a dispersing agent, 0.5-3 parts of a neutralizer and 0.5-2 parts of a thickening agent; and the average particle size of themanganese phosphate in the surface adjusting agent containing the manganese phosphate is 2 microns or below, D90 is 1.5 microns or below, and the PH value is 3-9. According to the surface adjusting agent containing the manganese phosphate, the stability is excellent, brushing is not needed after chemical conversion treatment of the iron and steel wear-resistant manganese phosphate, and the excellent treatability is realized.

Description

technical field [0001] The invention relates to the technical field of surface regulators, in particular, the invention relates to a surface regulator containing manganese phosphate. Background technique [0002] The main moving parts inside the refrigerator compressor, such as the crankshaft, piston, and outer bearings, have to work reciprocatingly under numerous high-temperature motions. In addition to ensuring the machining accuracy, it is also necessary to degrease the surface of the parts, adjust the surface, and use manganese phosphate chemistry. Converted and brushed, it helps to enhance the abrasion resistance of the outer surface and enhances the oil absorption of refrigeration oil. [0003] The purpose of the surface conditioning treatment is to rapidly, uniformly, and densely form a film of manganese phosphate crystals on the steel surface in the manganese phosphate-based chemical conversion treatment that is the next step. Usually, the iron and steel material is...
