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 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、漆膜柔韌性測(cè)試

2. Paint film flexibility test

通過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)。

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、涂膜光澤度的測(cè)定

3. Determination of glossiness of coatings

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 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、涂膜耐水性測(cè)試

4. Coating water resistance test

涂膜的耐水性是通過將涂膜浸入水或沸水中來(lái)測(cè)試的，它表示經(jīng)過一定時(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 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、涂膜耐熱性測(cè)試

5. Coating heat resistance test

涂膜的耐熱性是指通過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。各種集裝箱房屋涂料都有使用溫度范圍，溫度過高或過低都會(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、開裂、變色，使涂膜的保護(hù)性能喪失或變差。

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.
