Purification of heat treatment of various special salt
Heat treatment salt
Executive JB/T9202-2004 Standard
I take full advantage of the province's rich resources of the
coastal salt, after purification copied to produce high purity and
low impurities, heating the workpiece when the non-corrosive
high-quality salt, heat treatment salt in full compliance with
technical standards. My company have chloride dam, sodium chloride, potassium chloride,
as well as nitrates, carbonates and other kinds of salt, the user
can choose according to need.
First, salts and technical conditions:
