Colored aluminum roll for sale Haomei

Colored aluminum rolls for sale give rich colors to aluminum strips through paint coating, and have good gloss and smoothness, as well as superior texture and feel, and colored aluminum roll can also increase the sense of layering and three-dimensionality. It can protect objects exposed to the atmosphere and attacked by ultraviolet radiation, wind, rain, frost and snow; due to temperature difference, freeze-thaw cycles, corrosive gases and microorganisms, the coating can play a protective role.

Colored aluminum coils are widely used in many places, and its production process is also more complicated and strict, especially in coating. To ensure its coating effect, it is necessary to ensure that the following aspects meet certain requirements. raw materials. Coatings and aluminum rolls are the factors that most affect the coating quality in the coating process. Due to the color difference between batches of coatings, the fineness of the coatings is not enough and the coating rate is not high, and the coatings and solvents are poorly matched, delamination, etc. It directly affects the coating effect and produces defects. The unevenness of the colored aluminum roll substrate, the uneven film thickness, and the poor edge deflection also directly affect the product quality and overall use. Therefore, when selecting raw materials, it should be strictly controlled. equipment. The coating line requires the coating equipment to be in good condition, the coating equipment needs to run smoothly, there should be no horizontal and vertical jitter, and the coating roller needs to be finely ground. The lateral runout of all rollers of the coating machine must be controlled within the allowable range, otherwise it will seriously affect the coating surface quality process. The coating process is closely related to the quality of the coating, and it is required to control the relative line speed ratio of the coating roller, the paint roller, the metering roller and the substrate within a certain range. It is necessary to set a certain viscosity range for the coating according to different systems and the film thickness of the coating product to ensure the smooth progress of the coating and promote the improvement of product quality.

To ensure that the above standards are met, high-quality colored aluminum rolls can be produced, in order to meet the requirements of the majority of users, and the enterprise can be competitive.
