Scale and corrosion inhibitor Para B9305

Scale and corrosion inhibitor “B 9305” is a specially selected balanced composition of organic polymers and dispersants based on organic polyphosphonates and is designed to prevent salt precipitation and protect against corrosion of heat exchange equipment and communications in water circulation systems through cooling towers and for corrosion protection of black and non-ferrous metals. In some cases, this inhibitor is applicable in steam-condensate systems. 

Scale and corrosion inhibitor “B 9305” is produced in two grades A and B in accordance with the current specifications TU 2482-003-17423242-2008 with amendments. one.

Used in services

Protection of equipment of water circulation systems

Application

Inhibitor “B 9305” is constantly dosed into the water circulation system using a dosing pump. Dosing can be done directly from product drums or from working plastic containers. For ease of dosing, the reagent can be pre-diluted with water. It is considered more efficient to supply the reagent to make-up water. If the inhibitor is used in conjunction with a biocide, then it is applied after the biocide. Inhibitor “B 9305” is effective at evaporation rates up to 5.

Dosage

The dosage of the inhibitor “B 9305” depends mainly on the hardness of the water. As a general recommendation, we give the following dosages:

10-15 ppm with calcium hardness up to 2 meq; 15-25 ppm with water hardness up to 5 meq.; 25-50 ppm at water hardness 5-10 meq. Dosages and hardness values ​​are given for make-up water. In the initial application of the inhibitor, loading doses of approximately 50-100 ppm for 1-3 days are recommended to form a protective film.
