Coated Aluminum Coil Process Before Spraying
The colored aluminum rolls are a kind of aluminum coil, and there are several points that need to be paid attention to in the construction of colored aluminum rolls.
1. Temperature: when using a colored aluminum coil, it must be used under normal temperature. The temperature should not be too cold or too hot.
2. Wear and tear: check to see if there is any abrasion on the surface of the colored aluminum rolls.
3. Seal: it must be sealed to prevent water leakage in the rain.
The above points are the precautions of using colored aluminum rolls. If you want to ensure the quality of the project, you must strictly follow the above contents.
Painted aluminum rolls are popular with consumers because of their high quality products. The surface is exquisite and high-quality, but because of the different USES, the demand will be noticed when applied. So, what are the use of color aluminum rolls?
1. Temperature: if the application is to be put into use, the temperature should not be too hot or too cold under normal temperature. If it is the roof, the height should not be less than 10 degrees.
2. Check: before the device, check in time to ensure that the material on the roof has no appearance of wear and tear to ensure the normal application and ensure the life of the application under normal circumstances. At the same time, it is necessary to check whether the painted aluminum rolls are unvarnished, such as unvarnished, to determine the cause and adopt measures to continue processing.
Three, bolt head: the bolt head of fixed color aluminum coil should be sealed with water-proof material, so as to avoid rain into rust.
According to the specific circumstances, such as plant conditions, workpiece material, workpiece surface condition, production batch, quality requirement of choose painted aluminum coil coating pretreatment process, the following detailed introduce for you.
The commonly used equipment used in the pretreatment of color coated aluminum coil is spray type combined cleaning machine, which can be used for the process of oil, phosphating, passivation, cleaning and other processes by means of jet mechanical force and chemical action. There are mainly pre-degreasing, degreasing, washable I, acid wash, water wash II, neutralization, water wash III, table tuning, phosphating, washing IV, and passivation. Before the product is processed, the whole product is immersed in the surface treatment, and there are already many manufacturers of color coated aluminum. There are two kinds of manual control and automatic control. It is more advanced to adopt PLC program automatic control, can realize automatic transfer between the process.
