下面来说一下温控箱机箱机柜表面处理工艺 2.去氧化膜 一般来说温控箱机箱机柜机外壳表面通过自然形成的氧化膜一般都不均匀且是非连续薄膜，当我们对温控箱机箱机柜的表面进行涂装时必须提前对其进行彻底的清除处理，对于压铸件来说可使用硝酸来对表面进行氧化膜处理。去除氧化膜后我们还需用清水进行进一步处理。1.碱洗 在温控箱机箱机柜制作成型后并没有真正的完工我们还需对其进行碱洗为什么要对其进行碱洗呢 其实目的就是为了除去温控箱机箱机柜表面沾附的油污那么我们经常会用那些碱洗液配方进行组合呢 一般我们会采用Na2CO3、Na3PO4、Na2SiO3和添加剂组成。碱洗完还需用清水进行擦洗目的是擦除碱液残迹物。 3.化学转化 进行完前面的几步后我们还需要对其进行化学转化处理对其处理的目的是使温控箱机箱机柜表面形成密而均匀的连续薄膜，这一步的工艺处理其实就相当于对钢铁件表面进行的磷化处理工艺，但它也有所不同，一般使用的溶液不同。温控箱机箱机柜的电子外壳的转化膜以铬酸/盐酸、磷酸/盐酸和氟氢酸为基础，转化膜质量通常为215g/m2，转化膜形成后必须用清水清洗然后用热风干燥以增强膜层的硬度。
The general high quality chassis machine cabinet sheet metal processing less varnish, electroplating treatment, cheap material difference in the chassis of the chassis generally do grill, electroplating treatment, the purpose of doing this is to cover up its selection of poor material problems, and may also increase the thickness of the sheet. Not only is the cabinet cabinet surface treated, but the good heat dissipation is also very important for the cabinet.
In the vehicle environment, if the mechanical dynamic performance of the cabinet can not meet the corresponding index in the vehicle environment, it is easy to make the equipment failure and failure comprehensive in the bad environment, and let us know the specialized sheet metal of the chassis cabinet. In the process of the fixed ring is to better play a solid role in the process of transportation, and in the design to make the system more coordinated installation. We all know that the face tree skin temperature control box cabinet machine cabinet products to the appearance of the beautiful appearance, which means that the appearance is very important. For the temperature control cabinet, cabinet cabinet products, how to maintain the overall beauty of the cabinet of the temperature control cabinet. In fact, if we want to ensure that the overall temperature of the cabinet can last for a long time, we need to do more work on the surface treatment technology of the cabinet.
Selection of cabinet cabinet
The quality of the cabinet of the chassis is directly affected by the quality of the manufacturing process. The edge of the steel plate of the cabinet of the machine cabinet will not spread the edge, the sharp mouth, the burr and so on, and the naked corner is handled by the folded edge, and it is not easy to scratch the loader's hand. The positioning of each slot is also very precise, and it will not be embarrassed to install or misfit parts.
1, look at the function: the first consideration should be safety.
2, look at the steel plate, the steel plate must be thick. If you knock with your fingers, you can feel which thick and thin.
3, look at the spray paint, a qualified cabinet cabinet, all the steel needs to spray paint, and spray paint must be average, so as to good rust, dustproof and so on.
4, look at glass, glass must be a bit thicker, but also pay attention to whether there are cracks around the glass, if there is a crack, it means that there are hidden dangers, and to pay attention to whether it is difficult.
5, look at the layout of the structure. Generally speaking, the baffle should be more, and there are cooling holes. Some iron sheets used for fixing cables must be wrapped to prevent damage to cables. The side wall fans should be installed on the rear wall of the cabinet, because most of the heat generated at the rear part of the cabinet.
6, see the accessories, because the installation includes network cables, telecommunications cables and power cables, the need to buy a hook belt or a belt with teeth to effectively fix the cable in the cabinet. If the cabinet is equipped with cable management module, the cable can be fixed directly in the vertical installation rail.
7, look at the heat dissipation, estimate how big the heat of your device is, generally speaking, there are two to four fans at the top of the cabinet, and the fans are much better. There are also some screws and nuts for fixing the rack. It does not cause inconvenience due to insufficient fittings due to future expansion.
Nursing after forming the cabinet of the chassis
Generally speaking, there are two to four fans on the top of the chassis, and the side wall fans should be installed in the rear wall of the chassis. Why do they do this because the rear of the equipment will produce a large amount of heat to discharge the heat in time so that the side wall fan is installed in the rear wall of the chassis. Surface treatment and heat dissipation are especially important for cabinet cases. These two kinds of performance will be better for the distribution box. After each product is formed, we need to deal with it effectively, such as appearance and so on. The distribution cabinet is the same, so what do you need to do after the cabinet is formed? First of all, we need to deal with the surface. Only with proper surface treatment can we extend his life and improve his performance. Spraying and electroplating are the most commonly used methods for surface treatment of chassis. Its function is to prevent rust and antistatic, and to form a protective film at the same time. When it is not the cabinet cabinet possessive surface must be spray and electroplating. However, the radiator of the cabinet can not be separated from the fan, and the configuration of the fan can be considered by the amount of heat you put into the device.
Why is there a lot of fixed rings in the sheet metal processing of chassis cabinet?
Generally, there are many fixed rings in the process of sheet metal processing for chassis cabinet. These fixed rings play a lot of roles. Then we will find out why the design of the fixed ring power distribution system in the machine cabinet of the cabinet should follow the design of the reliability design as the core, the design of the machine cabinet system, the principle of full coordination and seamless coordination with the distribution system, and the convenience of installation at the same time.
How to deal with the surface of the cabinet cabinet of the temperature control box
After many years of experience in the cabinet production line of the thermostat box, I have summed up some experiences for reference.
