Embodiment Construction

[0022] The invention proposes that the separator adopts an aluminum-silicon alloy material, and the surface of the separator is coated with a phosphating film after phosphating treatment. The aluminum-silicon alloy material of the separator contains 17-32% Si, 5-10% Cu, 2-5% Zn, 0.6-2% Mn, 1-2% Mg, 0.7-1.5% Fe, 0.1% RE, and the remainder All are Al. Compared with the general aluminum alloy composition, the aluminum-silicon alloy material composition of the separator eliminates the addition of heavy metal antimony. Although heavy metal elements can increase the hardness and strength of the alloy, the element is poisonous and expensive. The removal of heavy metal elements can reduce it on the one hand. Cost, on the other hand, can reduce the harm to the environment and the human body, making the material more environmentally friendly. Preferably, the content of Zn and Mg in the aluminum-silicon alloy material of the separator is increased, which effectively promotes the formatio...

Abstract

The invention discloses an aluminum silicon alloy partition plate, a phosphating treatment method and a compressor. The partition plate adopts an an aluminum silicon alloy material, and the partitionplate is coated with a phosphating film after the surface of the partition plate is subjected to phosphating treatment. The wear resistance of the partition plate can be significantly improved, the requirement on the wear resistance of the partition plate under the unlimited working condition of the compressor is met, and the process cost of the partition plate is lower.

Description

Technical field [0001] The invention relates to the technical field of compressors, in particular to aluminum-silicon alloy separators, phosphating treatment methods and compressors. Background technique [0002] Compared with cast iron, conventional aluminum alloys are weaker in strength, hardness and wear resistance, and generally cannot be directly applied to the diaphragm of the compressor. The existing solution is to passivate, oxidize or phosphatize aluminum alloy separators to improve the strength and wear resistance of the separators. Although the cost of phosphating treatment is much lower than that of passivation treatment and oxidation treatment, and the phosphating film formed after phosphating treatment has better wear resistance, passivation treatment and oxidation treatment are used most in actual production, and phosphating treatment is very Rare, the main reason is that aluminum is mainly used in conventional aluminum alloys, and other alloying elements are gene...
