Power plants demineralized water tank is the steel roundness container,its body material usually is carbon steel,mainly used for storing the
demineralized water which prepared by the demineralizing equipment in power plant’s chemical workshop.During the storage of water,the water quality
shall not be polluted.Outlet water quality needs to achieve the chemical supervision guideline of water vapor in thermal power plant,the rules of the
DL/T561-95.But as a result of corrosion phenomenon,the water quality of storing demineralized water usually can not meet the above criteria.Therefore in
the process of production,we often adopt the method of making anti corrosion resistant protective coating,to prevent appearing the corrosion phenomena
in the demineralized water tank.

After many years’working together with a number of construction units,power plants and research institutions,Xiangyang City Hundred Shield Coating
Material Co.,Ltd developed and perfected a set of effective anti corrosion resistant protective coating production technology,have gained good reputation
among the power plants.They choose the materials of BD407 anti chemical corrosion resistant coating and BD408 high temperature flakes corrosion
resistant coating from Xiangyang City Hundred Shield Coating Material Co.,Ltd’s exclusive research & development and production.

The construction technology:
First clean up the demineralized water from water tank,and dry it by airing.Do the sand blasting treatment for the water tank inner wall,outer wall (sand blasting
effect is the best,but if you don’t have sand blasting conditions,you can do the polishing with angle grinder).Until to appear a fresh metal base.

Clean it by cleaning agent(you can choose acetone,ethyl acetate,alcohol etc.) and dry it by the airing,can also blow-dry with hot wind.Weld joint welding slag
and other sharp protrusion need to burnish to be flat and level.

According to the specified ratio,make the A and B two components of BD407 anti chemical corrosion resistant coating mix uniformly,and blade coating on the
surface of water tank base material,generally uses the method of criss cross to brush coating one time for horizontal and vertical,the coating should be compacted,avoid appearing the holes.

After the BD407 anti corrosion chemical resistant coating initial curing,make the BD408 high temperature flakes corrosion resistant coating mix uniformly
according to the specified ratio,then blade coating on the surface of BD407 anti corrosion resistant coatings,the coating should be compacted along one direction.

After the BD408 high temperature flakes anti corrosion resistant coating initial curing,make the A and B two components of BD407 anti chemical corrosion
resistant coating mix uniformly according to the specified ratio,and blade coating on the surface of BD408 high temperature flakes corrosion resistant coating,
the coating should be compacted,avoid appearing the holes.It can be put into using after placing it for 48 hours at room temperature.

Using this technology which recommended by xiangyang Hundred Shield Coating Material Co.,Ltd to be preparation of anti corrosion resistant protective coating
can effectively prevent the demineralized water tank appearing corrosion phenomenon,It can repair the demineralized water tank which has already appeared
corrosion phenomenon,and prolong its working life.
