The three main raw materials for Belclene 640 production are phosphorous acid, ammonium chloride, and formaldehyde.
The first two are added into the reactor and heated and stirred until dissolved completely.
Then, formaldehyde will be dropwise.
Phosphorus acid can be from the hydrolysis of PCl3 or the production of other chemicals.
If chlorine content needs to be lower than the normal specs, the steam-heating time will be extended.
Belclene 640 has excellent chelation.
Belclene 640s threshold inhibition is low and chemical stability is high.
Belclene 640 is an excellent antiscalant and chelating agent to most metal ions like Ca, Ba, Mg, Fe and Pb, especially Calcium Carbonate (CaCO3).
In the water system, Belclene 640 is difficult to hydrolyze and can distort the lattice.
In a higher concentrated system, Belclene 640 is also a good corrosion inhibitor.
Belclene 640 is used in industrial circulating cool water system of thermal power plant and oil refinery plant.
Belclene 640 can decrease scale formation and inhibit the corrosion of metal equipment and pipeline.
Belclene 640 can be used as a chelating agent in woven and dyeing industries and as a metal surface treatment agent.
Usually, Belclene 640 is compounded with organophosphorus acid/salt, polycarboxylic acid/salt.
Belclene 640 solid as crystal powder can also be supplied for cold areas, particularly in water.
Belclene 640 is easy to dissolve.
Belclene 640 is suitable for usage in winter and freezing districts.
Because of Belclene 640s high purity, it can be used in woven & dyeing industries and as a metal surface treatment agent.
Belclene 640 is usually used together with organophosphorus acid, polycarboxylic acid, and salt to built all organic alkaline water treatment chemicals.
Belclene 640 is broadly applied in recirculated cooling water systems for the power station, oil field, and central air-conditioning, etc.
Belclene 640 is also used in the woven and dyeing industry.
As an antiscalant and chelating agent, the recommended dosage is 1-20mg/L.
This will increase to 20-60mg/L is used as a corrosion inhibitor.
