环保型气相防锈剂的研制
Preparation of environment-friendly vapor phase inhibitor
摘要
Abstract
Being safe,non-toxic,environmental protection is the development trend of vapor phase inhibitor.In order to update and replace the vapor phase inhibitor with sodium nitrite as the main component in China,the environmental protection inhibi-tor is prepared.The corrosion inhibition of sodium benzoate,1 H-benzotriazole,hexamethylenetetramine,and cyclohexylamine carbonate is studied by static suspension method and dynamic salt spray test.The static antirust screening experiments are car-ried out with a single component and multi component.The effect of sodium benzoate,hexamethylenetetramine,1 H-benzotri-azoleand cyclohexylamine carbonate on corrosion behavior of Q235 steel sheet is studied in 5%(mass fraction)NaCl atmosphere. The experimental results show that the preferred formula of m(sodium benzoate):m(hexamethylenetetramine):m(1 H-benzotriazole):m(cyclohexylamine carbonate)is 5:2:2:1.The antirust effect of the formula is verified by the neutral salt spray test,and the sample remains bright and rustless after 1 5 d when it is used in the form of antirust film.This vapor phase inhibitor is safe and efficient with low toxicity and environmental protection,and it has synergistic effect,so it can be used for replacing the vapor phase inhibitor with sodium nitrite as the main component.关键词
