3. spray: with spray gun the Dacroment Zinc Based Comples Coatings dissolution homogeneity prepared is sprayed on each position, concurrent flow structure chiller core surface;
4. toast: temperature controlling range is toasted between 200 ~ 300 degree, 10 ~ 15 minutes time;
5. secondary spraying: the Dacroment zinc-base prepared met coating solution with spray gun and again to uniformly spray at each position, concurrent flow structure chiller core surface one time;
6. secondary baking, Dacroment technique baking temperature is in 250 ~ 350 scopes, and 20 ~ 40 minutes time, Dacroment Zinc Based Comples Coatings solution chemistry is reacted completely, and coating is firm;
7. adopt air blast to carry out cooling, dry.
Described step 3., 5. in adopt the coating procedure of Dacroment all to carry out in indoor.
In step bake process 4., temperature controls between 230 ~ 280 degree; In step secondary baking process 6., temperature controls between 280 ~ 320 degree.
Adopt the present invention of technique scheme, adopt the surperficial Dacroment processing method after improving, make anticorrosion grade reach 10/5vsA level.Test that its effect is shown in " modification salt fog test method ".
