An environment friendly and controlled release malfunction water treatment glass agent has been synthesized.Low materials for synthesized are extensive existed and safety in nature such as silicon and boron which have corrosion inhibition properties for steel and iron in water.This glass also has good active antibacteria through adding silver oxide,so it can be used as a good corrosion inhibitor,disinfection agent for multifunction water treatment agent when it controlled release in water.We research its co...
