提及彩涂铝卷，很多的人的印象就是表面多样的颜色，的确，众多的颜色为材料的使用增添了众多的砝码，同时也为客户提供了众多的使用选择余地，增加了材料的装饰性性能。
Referring to colored aluminum rolls, many people's impression is that the surface of a variety of colors, indeed, a large number of colors for the use of materials to add a lot of weight, but also to provide customers with a large number of options for use, increased the decorative properties of materials.
是外观，彩涂铝卷一改普通铝卷表面单一的颜色，涂层工艺的定义为彩涂铝卷增加了众多的使用筹码，更多的颜色被很好的诠释在铝卷材料的表面，不仅很好的装饰了使用环境，同时也变相的保护了彩涂铝卷。原理很简单，彩涂铝卷表面特殊的涂层的加入提升了材料的防锈防腐蚀性能，因为涂层也是一层特殊的保护隔绝，避免了空气中的水和氧气直接和金属层进行接触，产生化学反应。这一点彩涂铝卷厂家也是普通铝卷达不到的使用性能。
First of all, the appearance of color-coated aluminum coil changed to a single color on the surface of ordinary aluminum coil. The definition of coating technology is that color-coated aluminum coil adds a lot of usage chips. More colors are interpreted on the surface of aluminum coil materials. It not only decorates the use environment well, but also protects the color-coated aluminum coil in disguise. The principle is very simple. The special coating on the surface of color coated aluminum coil improves the anti-rust and anti-corrosion performance of the material, because the coating is also a special layer of protection and isolation, avoiding the direct contact of water and oxygen in the air with the metal layer, resulting in chemical reactions. This color coated aluminum roll manufacturer is also not commonly used for ordinary aluminum rolls.
其次是表面处理工艺上，相比普通铝卷，彩涂铝卷的表面处理工艺有了极大的提升，涂层特殊的适配性能让金属层和涂层有了更好的兼容性，涂层的刷涂变相的弥补了金属层表面的不足，同时在厚度处理工艺上彩涂铝卷也进行了了充分的优化，质量相比普通的铝卷有了进一步的缩小。
Secondly, the surface treatment process, compared with ordinary aluminum coil, color coated aluminum coil surface treatment process has been greatly improved. The special coating adaptability makes the metal layer and coating have better compatibility. The coating brush phase change makes up for the shortcomings of the metal layer surface, while the thickness treatment process of color coated aluminum coil is also carried out. With the full optimization, the quality of aluminum coil has been further reduced.
在使用性能上彩涂铝卷和普通铝卷之间的区别还是有一定的差异的，相比一般的铝卷材料，彩涂铝卷的可加工性更加的出众，同时在使用的过程中也更加的容易弯曲，带来巨大的使用便利。同时在环境适应能力上，彩涂铝卷的耐候性耐高温性也有了很大程度的提升，材料的强度以及耐刮性能都有了极大程度的改变。这些提升点都是由于彩涂铝卷基于普通铝卷上的设计以及独特工艺的使用。

There are still some differences between color-coated aluminum coil and ordinary aluminum coil in use performance. Compared with ordinary aluminum coil material, color-coated aluminum coil has more outstanding machinability, and it is easier to bend in the process of use, bringing enormous convenience. At the same time, the weatherability and high temperature resistance of color coated aluminum coils have been greatly improved, and the strength and scratch resistance of the materials have been greatly changed. These lifting points are due to the design of the coloured aluminum coil based on the ordinary aluminum coil and the use of unique technology.
综上所述，彩涂铝卷和普通铝卷的区别有很多，从运用的角度来说，彩涂铝卷明显的偏向特殊化，而普通铝卷则显得更加的大众化。当然，彩涂铝卷在很好的继承了铝材料优势的同时，也很好的在材料的制作成本上进行了优化，所以消费者可以放心的购买。
To sum up, there are many differences between color coated aluminum coil and ordinary aluminum coil. From the perspective of application, color coated aluminum coil is obviously biased towards specialization, while ordinary aluminum coil is more popular. Of course, color coated aluminum coil in a very good inheritance of the advantages of aluminum materials at the same time, but also very good in the material production cost optimization, so consumers can rest assured to buy.
每家的厨房里都有烟道，同时烟道也有主副之分，主烟道贯穿整个楼体，而副烟道是相对的。一般家里的油烟会先到副烟道里，然后再通过隔板上的孔进入主烟道，这样可保证每户的油烟是隔离开来的。而如果将副烟道直接连接主烟道，就会由于压力过低而导致倒烟或串烟现象。
Each kitchen has a flue, and the flue also has the main and secondary points, the main flue throughout the building, and the secondary flue is relative. Generally, the lampblack in the household goes into the sub-flue first, and then enters the main flue through the holes in the partition, so as to ensure that the lampblack in each household is isolated. If the auxiliary flue is directly connected to the main flue, the pressure will be too low and lead to backflue or smoke string phenomenon.
