Sodium Tungstate Compound Corrosion Inhibitor Copper Protection
Sodium tungstate is an inorganic inhibitor. It has many advantages, such as low toxicity, no harm to environment, human body and crops, and no microorganism breeding. However, sodium tungstate has its unavoidable defects. First of all, the effect of single sodium tungstate is limited, and it needs to be used to enhance the effect, at the same time, sodium tungstate is more expensive and impractical to use. Therefore, more enterprises are using sodium tungstate and cheaper chemicals to make sodium tungstate composite corrosion inhibitor to realize the function of protecting metal. Polyaspartic acid (PASP) is a newly found environmental friendly water treatment agent. It has excellent scale inhibition, dispersion and good biodegradability, after polyaspartic acid used efficiently, stably microorganisms, fungi degradation of the final product harmless to the environment, is a very desirable water treating agent. What is the effect of combining sodium tungstate with pol...
