1) the construction conditions. (1) construction site requirements. Now some construction units in the coating, the coating area open operation, affected by the atmospheric environment, cannot clean, dry and has been well cleaning on the surface of the coating and coating was flying dust, sand the surface of the grains of sand, water, grease, weld spatter or other dirt adhere to the above, affect the quality of paint film. Think in terms of cycle of life and value engineering, derusting and painting shall be carried out within the closed workshop, in order to protect the process quality. (2) the construction of the general requirements in 5 ~ 38 ℃ environment temperature, low temperature coating of the curing reaction stops, too high requires extensive use of diluent, affect the quality of paint film. Site should set the thermometer, according to the manufacturer to provide the product using the guidelines operating temperature conditions. (3) it is important to pay special attention to the relative humidity should be < 85%, steel temperature above the dew point temperature, in order to prevent the grassroots and dewing phenomenon before coating. Within 4 h after coating must not get wet in the rain, prevent moisture kept adding electrochemical reaction.
2) construction method. High-pressure airless spraying method has high power, the advantages of less paint loss, a thick coating, should choose as far as possible. Construction according to the top-down, outside, after the first difficult before they are easy, crisscrossed process for coating. The traditional roller coating, coating, by contrast, backward technology, quality control is difficult, should reduce use.
