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.
