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、涂層顏色檢查和外觀檢查

1. Coating color inspection and appearance inspection

確定集裝箱房屋的油漆顏色和外觀，需要采用目視的方法，將漆膜的顏色和外觀與標(biāo)準(zhǔn)色板和標(biāo)準(zhǔn)樣品進(jìn)行對(duì)比，進(jìn)行觀察和評(píng)價(jià)。油漆和施工前應(yīng)檢查油漆的顏色，涂在試板上的油漆干燥后，顏色應(yīng)與設(shè)計(jì)中規(guī)定的顏色相匹配。檢查通常與標(biāo)準(zhǔn)的顏色代碼進(jìn)行比較。漆膜外觀應(yīng)均勻、致密、富有光澤。

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、漆膜柔韌性測(cè)試

2. Film flexibility test

通過(guò)在不同直徑的軸桿上彎曲樣品板并在不損壞涂層的情況下表示較小軸桿的直徑來(lái)測(cè)量容器外殼涂層的柔韌性。涂膜柔韌性是指涂膜彎曲后附著在涂膜上的涂膜的綜合性能，與涂膜的拉伸強(qiáng)度、拉伸強(qiáng)度、厚度和附著力有關(guān)。

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、涂膜光澤度的測(cè)定

3. Determination of film gloss

當(dāng)光線照射到物體表面時(shí)，反射的光線的表現(xiàn)就是光澤。樣品的光澤度表示為在相同條件下，在給定入射角下，樣品表面的鏡面光量與標(biāo)準(zhǔn)樣品表面的鏡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、涂膜耐水性測(cè)試

4. Water resistance test of coating

涂膜的耐水性是通過(guò)將涂膜浸入水或沸水中來(lái)測(cè)試的，它表示經(jīng)過(guò)一定時(shí)間后涂膜的表面變化。耐水性是指涂膜浸入水中時(shí)發(fā)生的物理化學(xué)反應(yīng)的性能變化。漆膜的耐水性是檢驗(yàn)漆膜質(zhì)量的一項(xiàng)重要項(xiàng)目，因?yàn)樵S多涂料長(zhǎng)期在水中、地下或潮濕環(huán)境中使用。即使在水中長(zhǎng)期不使用，若產(chǎn)生氣泡、失去光澤、變色，或掉入水中，涂膜仍可恢復(fù)原狀，但涂膜質(zhì)量也變壞了。受其影響，保護(hù)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、涂膜耐熱性測(cè)試

5. Film heat resistance test

涂膜的耐熱性是指通過(guò)在空氣烘箱或高溫爐中加熱涂膜，使其表面發(fā)生合理變化或達(dá)到預(yù)定溫度和時(shí)間后的現(xiàn)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.

各種集裝箱房屋涂料都有使用溫度范圍，溫度過(guò)高或過(guò)低都會(huì)影響涂料質(zhì)量，特別是在高溫條件下使用的涂料需要檢查耐熱性，防止施工后使用。發(fā)生剝落、起泡、開(kāi)裂、變色，使涂膜的保護(hù)性能喪失或變差。

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.
