Corrosion resistant aluminum alloy passivator

Release date:2017-01-23 11:21 Source:http://www.zhiyuhg.com Click:

Corrosion-resistant aluminum alloy passivation agents are: ordinary trivalent chromium passivation agent, high temperature aluminum alloy passivation agent and corrosion-free chromium-free passivation of three.

Ordinary trivalent chromium passivator, the corrosion resistance of the film is a neutral salt spray time can basically reach more than 100 hours, up to 360 hours or more, when used to require clean and clean, with 10-15% Liquid, soak for 3-4 minutes; temperature-resistant trivalent chromium passivating agent, can be used for passivation, after high temperature conditions after the process, in order to ensure that the passivation film is not due to heat and crack design. The baking temperature must reach more than 150 degrees, can generate a stable passivation film. Heating 280 degrees, time 20-35 seconds in the case of its bare film resistant to neutral salt spray time can reach more than 48 hours. Corrosion-resistant chromium-free passivation agent, is dedicated to die-casting aluminum alloy environment-friendly passivation agent, film color for the character, bare metal salt spray up to 48-200H, the specific corrosion resistance and material properties are great Correlation.

Chromium-free passivation agent, in the production of practical applications is very wide, its performance is also quite superior.
