Coating device for fogdrop prevention solution and coating method thereof

Abstract

The invention discloses a coating device for a fogdrop prevention solution and a coating method thereof. The coating device for the fogdrop prevention solution comprises a baking oven A, a baking oven B, an upper compression roller, a lower coating roller, an extrusion roller and a liquid tank, wherein a row of infrared emission tubes are mounted at the lower part of the baking oven A; the baking oven A and the baking oven B are arranged side by side; the infrared emission tubes are respectively arranged above and below the baking oven B; the fogdrop prevention solution is accommodated in the liquid tank; the lower coating roller is mounted right above the liquid tank; the lower coating roller is partially immersed into the fogdrop prevention solution; the upper compression roller is mounted right above the lower coating roller; the extrusion roller is mounted on the right side of the lower coating roller; the center of the extrusion roller and the center of the lower coating roller are on the same plane. A fogdrop prevention coating can be completely cured better, the surface tension of condensate water is increased, a water film is formed by the condensate water, the condensate water drains outdoors gradiently, and the adhesive force is high, so that the coating is unlikely to be damaged and can be used for more than ten years in a natural environment.

Description

technical field [0001] The invention relates to the field of plate processing, in particular to an anti-fogging solution coating device and a coating method thereof. Background technique [0002] In the cold winter, due to the certain temperature difference inside and outside the greenhouse and the high humidity in the greenhouse, fog droplets will be generated, and the generated fog droplets will form semicircular convex mirrors to reflect sunlight, which will reduce the light transmittance and cause the greenhouse The internal light is greatly reduced and drips from the top, which affects the growth of plants in the greenhouse, or the leisure, dining, and sightseeing environment in the greenhouse, increases the humidity in the greenhouse, and increases the possibility of pests and diseases. [0003] Anti-fogging is a new application of PC sheet. Its main function is: when there is a temperature difference between indoor and outdoor, condensed water will be generated on th...

[0003] Anti-fogging is a new application of PC sheet. Its main function is: when there is a temperature difference between indoor and outdoor, condensed water will be generated on the inner surface of the sheet, which will drip after gathering. At present, the domestic PC sheet industry promises that all products can achieve anti-fogging function. , but most of them are just a marketing gimmick. Phenomena such as poor anti-fog effect, low adhesion, and short duration have become a common phenomenon. From the perspective of the entire market, no company can use the anti-fog function of PC sheets be truly practical
