对于防腐涂料的施工,涂料品质是影响防腐效果的一个重要因素。环氧富锌漆、环氧云铁中层漆、氯化橡胶面漆的主要特性和主要理化性能如表2、表3所示。从表2和表3可以看出,这些涂料可以满足防腐施工对涂料性能的要求。
涂装方法主要有:手工刷涂、辊涂、喷涂等。对于面积较小的基体表面,尤其是细圆柱状或球形的基体,采用喷涂施工时,涂料的流挂现象一般比较严重,这主要与试件形状及稀释剂的添加量有关;而且对细圆柱形或球形表面,采用喷涂施工时,涂料浪费很严重,一般用刷涂方法施工。
For the construction of anti-corrosion coatings, coating quality is an important factor affecting the corrosion protection effect. The main characteristics of the epoxy zinc rich paint, epoxy micaceous iron oxide intermediate paint, chlorinated rubber topcoat and main physicochemical properties as shown in Table 3, table 2. From table 2 and table 3 can be seen that these coatings can meet the requirements of the anti-corrosion construction of coatings performance.
Coating method is mainly: manual brush, roller coating, spraying, etc.. For the base surface, especially thin cylindrical or spherical surface, the flow of coatings is more serious, which is related to the shape of the specimen and the amount of diluent.
