Kekai molybdenum disk low toxicity , low pollution levels of environmental pollution , is a novel application of more Water treatment agent . In order to obtain a better release effect , molybdenium often with polyphosphates, grapesSugar, salt , zinc , BTA complex to use , so not only can reduce copper molybdenum make Dosage, but also improve corrosion effect , the amount of the complex molybdates by 200 ~ 500mg / LDecreased to 4 ~ 6mg / L. Molybdate film process, dissolved oxygen must be present, withou mCalcium ( or other divalent metal ion
s ) .
Molybdenum carbide has a high melting point and hardness, good thermal stability and mechanical stability, and excellent corrosion resistance and other characteristics. Molybdenum is a silvery white refractory metal, a melting point of 2615 ℃, density of 10.2 g / cm 3, the expansion coefficient is small, a special tube is almost the same coefficient of expansion of the glass. Molybdenum stable at room temperature is higher than 600 ℃, rapidly oxidized.
