铝卷的颜色多种多样，但有时厂家染出来的颜色达不到理想的效果，严重影响使用效果。那么哪些因素会影响卷材的染色呢？它的储存环境又是怎样的呢？
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层的厚度、孔隙率、透明度等。其中，薄膜层的厚度应保持在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、染液的温度。铝卷的染色分为冷染和热染两种。冷染在生产中使用时间长，染色均匀度控制较好；而热染时间较短，颜色较难控制。它的温度约为40-60°C。温度过高会降低染色的吸附，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。在染色过程中，高纯铝、铝镁、铝锰合金经过阳极氧化处理后，染色效果非常好，可以染成各种颜色；对于重硅或重铜的线圈，在染色过程中，只能染成深色、黑色等比较单调的颜色。
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、染液浓缩。铝卷的浓度与染色有关系。如果染浅色，浓度可以低一些，深色的浓度要高一些。
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.
一般来说，颜色较浅的为0.1-0.39g/L，颜色较浅的为1g/L，颜色较深的为3-5g/L，颜色较浓的为10-15g/L。为加强染色的吸附性，可采用低浓度的颜色进行延染，使染料分子更均匀地渗入氧化膜的孔隙深处，使染出的颜色更加和谐、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
储存环境应确保空气流通和干燥，不可以将其放置于潮湿的环境中。这主要是因为该产品属于有色金属，与水汽接触后会发生氧化还原反应，会在表面形成斑点，进而导致卷材表面受损。因此，对于卷材的存储而言，干燥的环境是非常必要的。
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.
外包装盒的密闭性。铝卷在出厂之前，厂家会在其外边套上一层塑料薄膜，膜内放置防潮的干燥剂，然后再包上一层包装盒，以防止物流运输过程中因为水分或雨天而导致卷材发生氧化。因此，对于该产品而言，如果不适用的话，我们是不建议打开包装的，如果发现包装发生破损也要立刻进行修复，以防对产品造成损坏。一般来说，在外包装不受损的前提下，该产品是可以长期放置的。
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.
铝卷生产厂家要您注意，铝卷在打开外包装使用后如果没用完的话，一定要将剩下的卷材再放回原包装中，按照之前的方法进行重新包装，并将其放置于干燥通风的地方，以保证剩下的产品不被氧化，在下次使用时依然可以呈现出良好的使用效果。
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.
