Wet curtain
Wet curtains are widely used in greenhouse cooling systems. The wet curtains used in greenhouses are basically paper wet curtains. Paper wet curtains are made of paperboard made of paper pulp with a wet strength agent added to it. They are corrugated and stacked in a certain pattern. They are then bonded with water-resistant glue and cut into shapes. Paper has the advantages of good wet strength, large water-air contact area, stable performance, and easy industrial production. At present, ceramic wet curtains have been developed based on the characteristics of ceramics such as strong water absorption, washability, and resistance to corrosion.
Composition and structure of wet curtain
The wet curtain is mainly composed of polymer water curtain paper. The wet paper curtain is a special product. After special treatment, it has high structural strength, corrosion resistance, and a service life of more than six years. . We can see from the light transmittance of the water curtain paper that it has low resistance and air permeability. This shows that the water curtain paper has excellent air permeability and moisture resistance, which can ensure that water evenly penetrates the entire water curtain wall. The water curtain is made of paper. The three-dimensional space design provides the maximum surface area for evaporation for heat exchange between water and air. It has high water resistance and a large evaporation ratio. The outer frame of the water curtain is made of aluminum alloy or galvanized sheet. The purpose of choosing these two materials It is to prevent rust. The structure of the outer frame is carefully designed. There is a slot for installing the water inlet pipe inside the upper frame. The water inlet pipe can be fixed inside the upper frame. The water inlet is in the middle. The water flows in from the water inlet and then passes through the water inlet pipe. Disperse the water evenly throughout the paper curtain. When installing the outer frame, first place a row of horizontal paper curtains in the upper frame. These horizontal paper curtains play the role of water separation to ensure that the entire paper curtain evenly seeps downwards, and then Arrange the prepared water curtain papers side by side and put them into the connected frame. Put the spliced water curtain papers upright, then drill holes on the four sides of the water curtain and fix it with air nails. In this way, a greenhouse water curtain is made. Completed
