TH-503 Scale and Corrosion Inhibitor for Boiler
Properties of Scale and Corrosion Inhibitor:
TH-503 is built with organophosphine and polycarboxylic acid. TH-503 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 of Scale and Corrosion Inhibitor:
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, TH-503 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 TH-503 .
Package and Storage of Scale and Corrosion Inhibitor:
25kg in plastic barrel. Storage in room shady and dry place for one year.
Safety Protection of Scale and Corrosion Inhibitor:
Though no toxic, this product is acidic and corrosive, once contacted with
skin, flush with water.
