Plastic Electroplating-Corrosion Resistance Test of Coatings
Huizhou City Boluo Tenglong Technology Co., Ltd. wholeheartedly serves you! Mainly engaged in plastic water electroplating processing, accompanying plastic injection molding processing, mold processing and so on!
The corrosion resistance test methods of the coating include outdoor exposure corrosion test and artificial accelerated corrosion test. Outdoor exposure tests are particularly useful for identifying the properties of coatings and plating processes used outdoors, and the test results can often be used as the basis for formulating thickness standards. The artificial accelerated corrosion test is mainly used to speed up the identification of the quality of the plating layer. However, any accelerated corrosion test cannot characterize and replace the actual corrosion environment and corrosion state of the coating, and the test results are relative.
Artificial accelerated corrosion test methods include neutral salt spray test, acetic acid salt spray test, copper accelerated acetic acid salt spray test, corrosion paste corrosion test, electrolytic corrosion test, sulfur dioxide corrosion test, hydrogen sulfide corrosion test, moisture test, etc.
