Phosphating at room temperature has entered the era of all-weather, slag-free, high-speed and free-adjustable color film. After years of efforts, our company has launched a new generation of high-performance room temperature fast phosphating agent BY-838, which does not contain heavy metal salts in normal phosphating. class.
Room temperature phosphating has entered the era of all-weather, all-slag-free, high-speed and free-form color film. After years of efforts, our company has launched a new generation of high-performance room temperature fast phosphating agent BY-808. The appearance of the film is gray to gray.
Zinc-calcium phosphating is a phosphating solution that was used in large scale in the late 1970s and in the early 1990s.
There are many types of chemical conversion coatings of aluminum and its alloys, of which are typically chromate
Our company is easy to discolor, black, and tarnished during direct cleaning and transportation of copper
This product is a trivalent chromium treatment product for treating the surface of aluminum and its alloys.
In view of the shortcomings of the spray-molding and dip-forming bonding force after galvanizing parts, our company developed the BY-243 zinc alloy treatment agent to effectively compensate for this defect.
For chemical oxidation of aluminum and its alloys, the oxide film on the surface of the workpiece is colorless and transparent.
BY-200 treatment agent is a weak acid metal descaling agent, which is more suitable for chemical cleaning before steel coating.
To reduce production costs and improve the stability of the agent, BY-915 is usually used at higher temperatures (55-70 ° C) and at more dilute concentrations.
Phosphating solution liquid is preferably heated with cold water and then heated
