TH-503 is built with organophosphine and polycarboxylic
acid. It has advantages of high efficiency of scale & corrosion
inhibition and good temperature tolerance.
TH-503 can be used
in water treatment of low pressure boiler. Boilers include radiator,
steam, locomotive, etc. This product can also be used as scale
and corrosion inhibitor in situation of desalination plant,
distillation and bus water tank.
Usage:
Add 200g per ton water of this product into
boiler make-up water. During operation, blow-off every hour,
5-10 second each time. If the boiler has heavy scale, increase
the quantity, and frequently blow-off. After 10-20 days'
continuous operation, stop the boiler, open the handhole,
remove the visible scale deposit to prevent conduit blockage,
then, the boiler may turn into normal operation again.
TH-503 would be better if the condense index of boiler water was
controlled within 10. Other parameters may refer to related
regulations (boiler water pH10-12, for example). pH value
should not be lower than 7.
The material of medicate tank should be
in plastic, concrete tank should be pretreated by anticorrosion
method, otherwise, it will be eroded by the medicine, and
the hardness will be increased much high.
Total hardness of boiler make-up water should
be lower than 200mg/L. Once too high hardness is countered,
lime or other methods should be used to lower it .
Package and Storage:
25kg in plastic barrel. Storage in room
shady and dry place for one year.
Safety Protection:
Though no toxic, this product is acidic
and corrosive, once contacted with skin, flush with water.
