In the summer when non-woven fabrics are used to prevent rain, if the rainfall is large, the rainwater can still seep through the non-woven fabric to the wall of the greenhouse, and the walls of the greenhouse will scour, the rainproof effect will be poor, and the non-woven fabric will be rained. After sun exposure, it will greatly shorten the service life of the nonwoven fabric. So what good method can not only enhance the rainproof effect of non-woven fabrics, but also extend the life of non-woven fabrics? A layer of cement slurry is poured on the non-woven fabric on the back slope of the greenhouse to enhance the anti-rain effect of the non-woven fabric and extend its service life. When the cement slurry is poured on the non-woven fabric, the cement slurry can penetrate into the fine pores of the non-woven fabric, and when it is dried, it can be connected into a sheet to enhance the ability of the non-woven fabric to resist rainwater erosion, and the dried cement can also be in the non-woven fabric. A protective layer is formed on the surface of the cloth to enhance the ability of the nonwoven fabric to resist sunlight. When pouring cement slurry onto a non-woven fabric, it cannot be used when the temperature is high on sunny days. When the temperature is high, moisture in the cement slurry will quickly evaporate, so that cement cannot be connected to the surface of the non-woven fabric, and the solidification strength of the cement Greatly reduced, the use of poor results. However, on cloudy days or in the sunny afternoon, when the sun goes down, the temperature is low, and when the water evaporation rate is small, the moisture in the cement slurry evaporates slowly, so that the cement slurry has enough time to penetrate into the pores of the non-woven fabric and is connected to Tablets, improve the solidification strength of cement, better use.
