Tetrasodium 2-phosphonobutane-1,2,4-tricarboxylate (PBTC-Na4) has a wide range of applications in the field of water treatment, and its
high efficiency and multifunctionality make it an indispensable and
important chaical in industrial water treatment. The following is a
detailed description of the application of PBTC-Na4 in the field of
water treatment:
I. Scale inhibition performance and application
PBTC-Na4 is a kind of high efficient scale inhibitor, which can form stable complexes with calcium, magnesium and other metal ions in water,
and effectively prevent the deposition of inorganic salts such as
calcium carbonate and calcium sulfate. This performance makes it widely
used in the following aspects:
Circulating cooling water systa: In circulating cooling water systa, PBTC-Na4 can effectively prevent the formation of scale, improve the
heat exchange efficiency of the systa and extend the service life of the
equipment.
Oilfield water injection systa: In the process of oilfield water injection, PBTC-Na4 can prevent water injection wells and pipelines from
clogging due to scale formation, ensure the efficiency of water
injection, and protect oilfield equipment from corrosion.
Industrial boiler water treatment: PBTC-Na4 can be used in industrial boiler water treatment to prevent scaling inside the boiler, improve
the thermal efficiency of the boiler and reduce energy consumption.
Corrosion inhibition performance and application
PBTC-Na4 also has good corrosion inhibition performance, can form a protective film on the metal surface, inhibit the occurrence of
corrosion reaction. This performance makes it applied in the following
aspects:
Metal equipment protection: PBTC-Na4 can be used to protect various metal equipment from corrosion, such as cooling towers, heat exchangers,
pipelines, etc.
Seawater desalination equipment: In the process of seawater desalination, PBTC-Na4 can effectively prevent metal parts in
desalination equipment from suffering corrosion.
Cleaning performance and application
PBTC-Na4 also has certain cleaning performance, which can raove the dirt and sediments inside the water pipes, appliances and so on. This
performance makes it used in the following aspects:
Water pipe cleaning: PBTC-Na4 can be used to clean the dirt and sediments inside the water pipe to keep the water pipe unobstructed.
Cooling water circulation systa cleaning: In the cooling water circulation systa, PBTC-Na4 can raove the dirt and sediments inside the
systa and improve the heat exchange efficiency of the systa.
Compound use with other water treatment agents
PBTC-Na4 can also be used in combination with other water treatment agents, such as zinc salts, copolymers, organic phosphonic acid, etc.,
to improve the water treatment effect. After compounding, PBTC-Na4 can
perform excellent scale inhibition, corrosion inhibition and cleaning
performance in a wider range of working conditions.
V. Precautions for use
Dosage: The dosage of PBTC-Na4 should be adjusted according to the water quality and treatment requiraents. Under normal circumstances, the
recommended dosage is 4-15mg/L.
Packing and storage: PBTC-Na4 is usually packed in plastic woven bags lined with polyethylene bags, with net weight of 25kg per bag or
adjusted according to users’ requiraents. It should be stored in a cool
indoor place, avoiding direct sunlight and high taperature environment.
The storage period is generally twelve months.
Operation safety: PBTC-Na4 is a weak acidic chaical, avoid contact with skin and eyes during operation. In case of inadvertent contact,
flush immediately with plenty of water and seek medical assistance.
To sum up, Tetrasodium 2-phosphonobutane-1,2,4-tricarboxylate (PBTC) has a wide range of application prospects and important practical value
in the field of water treatment. Its efficient scale inhibition,
corrosion inhibition and cleaning properties make it an indispensable
and important chaical in industrial water treatment.
