What about pvc lay flat hose blockage?


In the application of PVC lay flat hose, sometimes blockage occurs, affecting the application of products, so we need to grasp the causes of blockage, and find out the corresponding solutions. Here we will learn about the relevant information.
The blockage of PVC lay flat hose may be caused by sediment and organic matter in rivers, lakes, pools and other water, or by chemical precipitation blockage of water flow caused by changes in temperature, velocity and pH, some chemicals which are not soluble in water deposit on pipes or drippers. This is that we can use acid flushing method to precipitate calcium carbonate. We can use 0.5%-2% hydrochloric acid solution to input drip irrigation system with 1 meter water head pressure, and the solution stays for 5-15 minutes. When blocked by calcareous clay, it can be washed with sand acid flushing solution.
For PVC lay flat hose blockage, pressure dredging method can also be used to flush drip irrigation system with compressed air or pressure water of 5.05 *105-10.1 *105 Pa, which has good effect on dredging organic matter blockage, but this method is ineffective for carbonate blockage.
