1、涂层颜色检查和外观检查

1. Coating color inspection and appearance inspection

确定集装箱房屋的油漆颜色和外观，需要采用目视的方法，将漆膜的颜色和外观与标准色板和标准样品进行对比，进行观察和评价。油漆和施工前应检查油漆的颜色，涂在试板上的油漆干燥后，颜色应与设计中规定的颜色相匹配。检查通常与标准的颜色代码进行比较。漆膜外观应均匀、致密、富有光泽。

To determine the paint color and appearance of container houses, it is necessary to use visual methods to compare the color and appearance of the paint film with the standard color palette and standard samples for observation and evaluation. Before painting and construction, the color of the paint should be checked. After the paint applied to the test panel is dry, the color should match the color specified in the design. Inspection is usually compared to standard color codes. The appearance of the paint film should be uniform, dense, and glossy.

2、漆膜柔韧性测试

2. Paint film flexibility test

通过在不同直径的轴杆上弯曲样品板并在不损坏涂层的情况下表示较小轴杆的直径来测量容器外壳涂层的柔韧性。涂膜柔韧性是指涂膜弯曲后附着在涂膜上的涂膜的综合性能，与涂膜的拉伸强度、拉伸强度、厚度和附着力有关。

Measure the flexibility of the container shell coating by bending the sample plate on different diameter shaft rods and representing the diameter of the smaller shaft rods without damaging the coating. Coating flexibility refers to the comprehensive performance of the coating film attached to the coating film after bending, which is related to the tensile strength, tensile strength, thickness, and adhesion of the coating film.

3、涂膜光泽度的测定

3. Determination of glossiness of coatings

当光线照射到物体表面时，反射的光线的表现就是光泽。样品的光泽度表示为在相同条件下，在给定入射角下，样品表面的镜面光量与标准样品表面的镜面光量之比的百分比。

When light shines on the surface of an object, the reflection of light is known as gloss. The glossiness of a sample is expressed as the percentage of the specular light on the surface of the sample to the specular light on the surface of the standard sample at a given incident angle under the same conditions.

4、涂膜耐水性测试

4. Coating water resistance test

涂膜的耐水性是通过将涂膜浸入水或沸水中来测试的，它表示经过一定时间后涂膜的表面变化。耐水性是指涂膜浸入水中时发生的物理化学反应的性能变化。漆膜的耐水性是检验漆膜质量的一项重要项目，因为许多涂料长期在水中、地下或潮湿环境中使用。即使在水中长期不使用，若产生气泡、失去光泽、变色，或掉入水中，涂膜仍可恢复原状，但涂膜质量也变坏了。受其影响，保护性能降低。

The water resistance of the coating is tested by immersing the coating in water or boiling water, which represents the surface changes of the coating after a certain period of time. Water resistance refers to the performance changes of the physical and chemical reactions that occur when the coating is immersed in water. The water resistance of paint film is an important item for testing the quality of paint film, as many coatings are used in water, underground, or humid environments for a long time. Even if not used in water for a long time, if bubbles, loss of gloss, discoloration, or falling into water occur, the coating can still be restored to its original state, but the quality of the coating also deteriorates. Affected by it, the protection performance decreases.

5、涂膜耐热性测试

5. Coating heat resistance test

涂膜的耐热性是指通过在空气烘箱或高温炉中加热涂膜，使其表面发生合理变化或达到预定温度和时间后的现象。各种集装箱房屋涂料都有使用温度范围，温度过高或过低都会影响涂料质量，特别是在高温条件下使用的涂料需要检查耐热性，防止施工后使用。发生剥落、起泡、开裂、变色，使涂膜的保护性能丧失或变差。

The heat resistance of a coating refers to the phenomenon of heating the coating in an air oven or high-temperature furnace to cause reasonable surface changes or reach a predetermined temperature and time. All types of container house coatings have a temperature range for use, and temperatures that are too high or too low can affect the quality of the coatings. Especially for coatings used under high temperature conditions, heat resistance needs to be checked to prevent use after construction. Peeling, bubbling, cracking, and discoloration occur, resulting in the loss or deterioration of the protective performance of the coating.
