system or hot-water system which use media like industrial water, pure water, glycol, etc.
Corrosion inhibitor SHQ-302 is composed of nitrites, molybdate, corrosion inhibitors
and scale inhibitors.SHQ-302 is mainly used for closed-circuit water system as prevention
rust and corrosion on steel and similar materials.
Corrosion inhibitor SHQ-303 use phosphate as main agent, assistant with cathode
protection, It is applied as pre-filming agents or corrosion inhibitors for open recycling
cooling water system.
Corrosion-inhibit upgrading agent SHQ-501B can be used together with organic
alkaline water treatment agents such as corrosion inhibitor of SHQ-501, this product is
suitable for application in cold state operation, low cycles of concentration operation and
various low-hardness complementary water. With the advantage of quick filming and film
repairing effect as well as thin and dense protectively filming, SHQ-501B offers good
functions for pre-filming, chemical cleaning and low alkalinity operation.
