氧化铝彩钢板存在色差几个原因

1材料氧化时,处理效果受成分、含量、浓度、温度、处理时间等因素影响,会产生不同的产品效果;
2在产品的封闭着色过程中,原料预处理生产中存在的色差增加了样品匹配、配色和配色的难度;

三。不同批次原材料铝板的金属元素含量和材质不一致,在着色处理中经过多次调整和样品评定,很难达到与样品相同的效果。
从以上因素可以看出,造成色差的因素很多,如原材料、处理液、处理时间、处理温度等,由于色差问题,一些下游客户不敢使用阳极氧化铝板。尽管它在性能上有很多优势,但人们对它仍心存疑虑。
为解决这一问题,应在设备上投入连续辊对辊阳极氧化项目;在原材料方面,应与我国两大热轧生产基地SWA和中铝建立合作伙伴关系,确保原材料质地的一致性和产品的稳定性。线圈生产设备能保证整个线圈产品的成分、含量、浓度、温度、加工时间的一致性,从而有效控制产品的色差范围,保证产品质地的一致性。
以上就是铝板色产生的原因。造成氧化铝板色差的因素很多,如原材料、处理液、处理时间、处理温度等,氧化铝板的色差是不可避免的,也是阳极氧化铝板的一个特点。但是,每个企业都会规定一个色差范围,范围内的产品都是正常产品。

1. When the material is oxidized, the treatment effect is affected by the composition, content, concentration, temperature, treatment time and other factors, which will lead to different product effects;

2. In the closed coloring process of products, the color difference existing in the production of material pretreatment increases the difficulty of sample matching, color matching and color matching;
3. The metal element content and material texture of different batches of raw material aluminum plate can not be consistent, and it is difficult to achieve the same effect as the sample after many adjustments and sample evaluation in coloring treatment.
From the above factors, we can see that there are many factors causing color difference, such as raw materials, treatment liquid, treatment time, treatment temperature, etc. Because of the color difference problem, some downstream customers dare not use anodized aluminum plate. Even though it has many advantages in performance, people still have doubts about it.
In order to solve this problem, continuous roll to roll anodizing project should be put into production on the equipment; in terms of raw materials, cooperative partnership should be established with China's two major hot rolling production bases, namely, SWA and Chinalco, to ensure the consistency of raw material texture and product stability. The coil production equipment can ensure the consistency of the composition, content, concentration, temperature and processing time of the whole coil product, so as to effectively control the color difference range of the product and ensure the consistency of the product texture.
The above is the reason why there is color difference in aluminum oxide plate. There are many factors causing color difference in aluminum oxide plate, such as raw materials, treatment solution, treatment time, treatment temperature, etc. The color difference of aluminum oxide plate is unavoidable, and it is also a characteristic of anodized aluminum plate. However, every enterprise will regulate a range of color difference, and the products within the range are normal products.
