Method of application

 

Used in metal substrate surface

1. Polished inner surface of cast iron pipe or steel container

Polish inner surface of cast iron pipe or steel vessel，and clean up all all the debris. There should be no more than 50% of the lining of the inner tube of metal protruding tumor thickness, etc.
2．Sandblast  inner surface of Cast iron pipe or steel container
　All interior surfaces sandblasted to reach GB / T Sa 1/2 8923 level (near white level)
3．Cast iron pipe or steel container linings
   ①After heated to 70 ℃，hang the cast iron pipe or steel container l on the turntable
　 ②The groups A and B of epoxy ceramic coating are heated to 70 ℃in a state of agitation
　 ③Tubes or containers are rotate on the turntable, then using a spraying machine , 1: 1 ratio of epoxy ceramic coating should be sprayed to the surface of the tube or the container which is maintaining 65 ℃~ 70 ℃, and the inner liner should be reach to a specified thickness in the contract after once cured.
　 ④Tube or container on the turntable continues to rotate, 50 ℃~ 65 ℃hot air from the stove should be blow into pipe or container, until the surface of the lining completely cured, it should be switched into health oven maintaining at least above 20 ℃in 24hs, then, the liner fully cured.

For concrete substrate surface

Concrete substrate subject to at least 28 days of the Nature Conservancy. After completely dry, remove surface dust and dirt and then use this product for coating.

Construction environmental conditions: substrate temperature should be above the dew point 3 ℃, relative humidity less than 85%, and it is not suitable for construction when outdoor temperature is below 5 ℃. Indoor heating measures can be taken without compromising security, such as preheating surface or dried with hot air ventilation and so on.

 

Precautions

1.  When used for drinking water container and the pipe wall, it should be taken to ensure that the required time is to enough, so that the coating can completely cured.

2.  Before officially putting into use, it should be rinsed at least 2 to 3 times with clean water, and then rinsed twice with adequate drinking water.
