In the laboratory coating, the coating of different samples often needs to cooperate with different conditions to better complete the coating and achieve a good coating effect. The one with high viscosity needs to be scraped slowly and use a scraper, while the one with low viscosity has particularly good leveling, so it needs to speed up and control its excessive flow, which will affect the coating effect.
Therefore, for samples with low viscosity and good leveling, it is often necessary to have a laboratory automatic coating machine with a drying function to accelerate the drying of the coating film and avoid excessive leveling from affecting the uniformity of the coating film. Commonly, the coating film is dried by heating the bottom plate. So is there any other way to dry the coating film more quickly?
The answer must be yes, and this is what I have learned recently. Nitrogen is used to accelerate the drying of the coating film, which can be dried faster than the bottom plate.
Let's spread nitrogen first. Nitrogen is an inert, colorless, odorless gas, and an inert gas that will not oxidize and corrode electrical components that require a gas source. Familiar with it is nitrogen drying. Do inert to preserve material, use in dry box or glove bag. For example, the nitrogen-filled Drying Oven is used for baking and heating of high-temperature and easily oxidized products by filling nitrogen; in addition, natural gas pipeline drying also uses nitrogen to absorb moisture and so on.
Therefore, if a nitrogen nozzle is installed on the experimental automatic film coating machine, the effect of drying the coating film can be achieved, and the drying speed is faster than that of the bottom plate. Moreover, nitrogen is a non-polluting gas, which is relatively safe and environmentally friendly. If you are interested in the automatic coating machine for nitrogen drying, you can consult the technical engineers of Beichao.
