鋁卷的顏色多種多樣，但有時廠家染出來的顏色達不到理想的效果，嚴重影響使用效果。那么哪些因素會影響卷材的染色呢？它的儲存環境又是怎樣的呢？
The color of aluminum coil is various, but sometimes the color dyed by the manufacturer can not reach the ideal effect, which seriously affects the use effect. So what factors will affect the dyeing of coiled materials? What is its storage environment?
1.氧化膜。氧化膜是指卷材薄膜層的厚度、孔隙率、透明度等。其中，薄膜層的厚度應保持在10um以上。
1. oxide film. Oxide film refers to the thickness, porosity, transparency, etc. of the coil film layer. The thickness of the film layer shall be kept above 10um.
2、染液的溫度。鋁卷的染色分為冷染和熱染兩種。冷染在生產中使用時間長，染色均勻度控制較好；而熱染時間較短，顏色較難控制。它的溫度約為40-60°C。溫度過高會降低染色的吸附，容易造成卷材表面起霜。
2. Temperature of dye solution. The dyeing of aluminum coil can be divided into cold dyeing and hot dyeing. Cold dyeing takes a long time in production and the dyeing uniformity is well controlled; However, the heat dyeing time is short and the color is difficult to control. Its temperature is about 40-60 ° C. Too high temperature will reduce the adsorption of dyeing, which is easy to cause frost on the surface of coiled material.
3、原材料。在染色過程中，高純鋁、鋁鎂、鋁錳合金經過陽極氧化處理后，染色效果非常好，可以染成各種顏色；對于重硅或重銅的線圈，在染色過程中，只能染成深色、黑色等比較單調的顏色。
3. Raw materials. In the dyeing process, high-purity aluminum, aluminum magnesium and aluminum manganese alloys can be dyed into various colors after anodic oxidation treatment; For heavy silicon or heavy copper coils, only dark, black and other monotonous colors can be dyed in the dyeing process.

4、染液濃縮。鋁卷的濃度與染色有關系。如果染淺色，濃度可以低一些，深色的濃度要高一些。
4. Dye concentrate. The concentration of aluminum coil is related to dyeing. If you dye light colors, the concentration can be lower, and the concentration of dark colors should be higher.
一般來說，顏色較淺的為0.1-0.39g/L，顏色較淺的為1g/L，顏色較深的為3-5g/L，顏色較濃的為10-15g/L。為加強染色的吸附性，可采用低濃度的顏色進行延染，使染料分子更均勻地滲入氧化膜的孔隙深處，使染出的顏色更加和諧、牢固.
Generally speaking, the lighter color is 0.1-0.39g/l, the lighter color is 1g/l, the darker color is 3-5g/l, and the thicker color is 10-15g/l. In order to strengthen the adsorption of dyeing, the low concentration color can be used for extended dyeing, so that the dye molecules can penetrate into the pores of the oxide film more evenly, and the dyed color is more harmonious and firm
儲存環境應確保空氣流通和干燥，不可以將其放置于潮濕的環境中。這主要是因為該產品屬于有色金屬，與水汽接觸后會發生氧化還原反應，會在表面形成斑點，進而導致卷材表面受損。因此，對于卷材的存儲而言，干燥的環境是非常必要的。
The storage environment shall ensure air circulation and dryness, and shall not be placed in a humid environment. This is mainly because the product is a non-ferrous metal, which will undergo oxidation-reduction reaction after contacting with water vapor, which will form spots on the surface, resulting in damage to the coil surface. Therefore, a dry environment is very necessary for the storage of coiled materials.
外包裝盒的密閉性。鋁卷在出廠之前，廠家會在其外邊套上一層塑料薄膜，膜內放置防潮的干燥劑，然后再包上一層包裝盒，以防止物流運輸過程中因為水分或雨天而導致卷材發生氧化。因此，對于該產品而言，如果不適用的話，我們是不建議打開包裝的，如果發現包裝發生破損也要立刻進行修復，以防對產品造成損壞。一般來說，在外包裝不受損的前提下，該產品是可以長期放置的。
Tightness of outer packing box. Before leaving the factory, the manufacturer will put a layer of plastic film on the outside of the aluminum coil, put moisture-proof desiccant in the film, and then wrap a layer of packaging box to prevent the coil from oxidation due to moisture or rain during logistics and transportation. Therefore, for this product, if it is not applicable, we do not recommend opening the package. If the package is found damaged, it should be repaired immediately to prevent damage to the product. Generally speaking, the product can be stored for a long time on the premise that the outer packaging is not damaged.
鋁卷生產廠家要您注意，鋁卷在打開外包裝使用后如果沒用完的話，一定要將剩下的卷材再放回原包裝中，按照之前的方法進行重新包裝，并將其放置于干燥通風的地方，以保證剩下的產品不被氧化，在下次使用時依然可以呈現出良好的使用效果。
The aluminum coil manufacturer should pay attention to that if the aluminum coil is not used up after opening the outer packaging, the remaining coil must be put back into the original packaging, repackaged according to the previous method, and placed in a dry and ventilated place to ensure that the remaining products are not oxidized and can still show a good use effect in the next use.
