The agent is a light yellow homogeneous solution with a variety of promoting components. Used in combination with the normal low temperature phosphating series,
In general, zinc phosphating for spraying contains heavy metal zinc ions, phosphates, nitrites, etc., and in phosphating, water washing water also dissolves substances that can harm the environment and the human body.
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.
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
