What to do if the layflat hose is blockedWhat to do if the layflat hose is blocked
The water belt is blocked by the following two methods. One is to use the pressure dredging method, which is to use a certain specification of compressed air or pressure water to flush the drip irrigation system. This has a good effect on dredging the clogging of organic matter, but this method is effective. Carbonate blockage is ineffective. If it is carbonate clogging, you need to use acid to flush, which is to use the principle of chemical reaction between acid and alkali. It is recommended to precipitate calcium carbonate first, and then use 0.5% to 2% hydrochloric acid solution. The 1 meter head pressure is input into the drip irrigation system, and the solution stays for 5-15 minutes.
When choosing a hose, we must pay attention to judging the quality of the product and choose a suitable hose to achieve better application effects. The production of the hose should comply with relevant industry regulations. The raw material of the product is 20 large chemical fiber polyester woven by a circular loom. The thickness must be more than 1.5mm, and no deviation is allowed; its pressure must be more than 0.6Mpa and the surface is smooth. It should be flat and free of defects such as wire breakage, warp drawing, warp loosening, internal and external grooves, deplasticizing pores, and impurities in the coating; the wall thickness should be uniform, and the aging agent should be added in line with industry standards.
