济南集装箱房怎么检验漆膜?来源:http://www.jnpkjzx.com   时间:2022-03-16
购买济南集装箱房时,我们要注意外面的漆膜,集装箱房的漆膜质量影响使用寿命,那么如何检查漆膜呢?
When purchasing Jinan container room, we should pay attention to the paint film outside. The quality of the paint film of the container room affects the service life, so how to check the paint film?
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 the container house, it is necessary to use the visual method to compare the color and appearance of the paint film with the standard color plate and standard sample for observation and evaluation. Before painting and construction, the color of the paint shall be checked. After the paint applied on the test plate is dry, the color shall match the color specified in the design. The check is usually compared with the standard color code. The appearance of the paint film shall be uniform, dense and shiny.
2、漆膜柔韧性测试
2. 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。
The flexibility of the container shell coating is measured by bending the sample plate on shaft rods of different diameters and representing the diameter of the smaller shaft rod without damaging the coating. Film flexibility refers to the comprehensive performance of the film attached to the film after bending, which is related to the tensile strength, tensile strength, thickness and adhesion of the film.
3、涂膜光泽度的测定
3. Determination of film gloss
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 reflected light is glossy. The gloss of the sample is expressed as the percentage of the ratio of the amount of mirror light on the sample surface to the amount of mirror light on the standard sample surface under the same conditions and at a given incident angle.
4、涂膜耐水性测试
4. Water resistance test of coating
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 film is tested by immersing the film in water or boiling water, which indicates the surface change of the film after a certain time. Water resistance refers to the performance change of physical and chemical reaction when the film is immersed in water. The water resistance of paint film is an important item to test the quality of paint film, because many coatings are used in water, underground or humid environment for a long time. Even if it is not used in water for a long time, if there are bubbles, loss of luster, discoloration, or falling into water, the film can still be restored to its original state, but the film quality is also deteriorated. Affected by it, the protection performance is reduced.
5、涂膜耐热性测试
5. Film 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。
The heat resistance of the film refers to the phenomenon that the surface of the film changes reasonably or reaches the predetermined temperature and time by heating the film in an air oven or high-temperature furnace.
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。
All kinds of coatings for container houses have a range of application temperature. Too high or too low temperature will affect the coating quality, especially the coatings used under high temperature conditions need to check the heat resistance to prevent use after construction. Peeling, blistering, cracking and discoloration occur, resulting in the loss or deterioration of the protective performance of the film.
