Why roller coating aluminum with the better paint performance than spray coating aluminum?




For the color coating aluminum coil/sheet,the roller coating way has the following advantages over spraying:


1)Roller coating has a fast coating speed and high productivity, with a maximum speed of 244m/min, while spraying is limited by the uniformity of the spray and drying time, which is relatively slow.


2)Roller coating does not produce paint mist in the coating process, there is no paint mist splash, making the coating efficiency close to 100%, while spraying produces paint mist, which pollutes the environment and requires a longer drying time.


3)Roller coating adapts to low-viscosity and high-viscosity coatings, and can be applied to a variety of film thicknesses ranging from 3-5 μm to 300-500 μm, whereas spraying is relatively less adaptable to the viscosity of coatings.


4) The coating effect of roller coating is uniform and the thickness can be controlled accurately, while the effect of spraying is affected by a variety of factors, such as the uniformity of the spray, the drying time of the paint, etc., and it is difficult to ensure the stability of the coating effect.


5)Roller coating equipment costs less, usually at a price of about tens of thousands of yuan, while a sprayer needs at least more than 100,000 yuan to buy.


In summary, roller coating compared to spraying has the advantages of fast coating speed, high efficiency, good adaptability, environmental protection, etc. In order to meet the premise of the use of the same paint, it is recommended to use roller coating.
