2. adopt mechanical ball blast method to clean: the diameter range of the shot that shot-blasting machine uses is 0.1-0.6mm, then uses the compressed air dedusting; Part temperature after the ball blast dedusting is removed concurrent flow structure condenser core surface impurity when being down to 20 ℃, and is removed each position burr up to 60 ℃ of left and right;
3. spraying: the Dacroment Zinc Based Comples Coatings solution for preparing is uniformly sprayed at each position, concurrent flow structure chiller core surface with spray gun;
4. baking: temperature controlling range is toasted between 200 ~ 300 degree, 10 ~ 15 minutes time;
5. secondary spraying: with spray gun, the Dacroment zinc-base for preparing is met coating solution and again uniformly spray at each position, concurrent flow structure chiller core surface one time;
6. secondary baking, Dacroment technique baking temperature in 250 ~ 350 scopes, 20 ~ 40 minutes time, Dacroment Zinc Based Comples Coatings solution chemistry is reacted completely, coating is firm;
7. adopt air blast to carry out cooling, dry.
Described step 3., 5. the middle coating procedure of Dacroment that adopts all carries out indoor.
In step bake process 4., temperature is controlled between 230～280 degree; In step secondary baking process 6., temperature is controlled between 280～320 degree.
Adopt the present invention of technique scheme, adopt the surperficial Dacroment processing method after improving, make anticorrosion grade reach the 10/5vsA level.Its effect is seen " modification salt fog test method " test.
