pretreatment filming agent
Molecular formula :
MW :
CAS :

nature : Pretreatment of the water treatment process, in the pre-formed metal surface protection film of a category of chemicals. If Sodium Hexametaphosphate plus zinc, such as sodium tripolyphosphate. The purpose of the pre-film is the use of chemicals in the early stage of corrosion inhibition and improve pharmaceutical dosage levels; In normal operation the addition of a small amount of corrosion inhibitor can maintain and repair the protective film, pharmaceutical and cost savings.
