Embodiment 1
[0061] The micro-irrigation pipe product of embodiment 1 has a large water permeability and is suitable for plants with high water demand. However, because the pipe wall is thin, the bulk density is small, and the strength is low, in order to shorten the production cycle, the value of L is the best with 2000mm.
Embodiment 2
[0062] Example 2 φ=16mm, H=40mm, L=3000mm, bulk density=400±20kg / m 3
[0063] 1. If image 3 , where φ=16mm, H=40mm, L=3000mm, bulk density=400±20kg / m 3 . Lift the micro-irrigation pipe mold and fasten the screw 7, apply a release agent on the part of the micro-irrigation pipe mold that may contact the foam concrete slurry, first put on the mold pipe 10 and position the nut 11 at one end, and then tighten the other end The nut of the mold pipe 10 is straightened;
[0064] 2. Use high-quality foam concrete foaming agent, use a foaming machine to make foam with a foam diameter of 0.08-0.12mm, and use ordinary Portland cement, 1% polypropylene fiber by mass, and 60% water to make concrete slurry , and mix the foam with concrete slurry to make a dry bulk density of 400±20kg / m 3 foam slurry, and then pour it into the micro-irrigation pipe mold;
[0065] 3. Scraping, under the condition of 20°C, after 6 hours, after the initial setting of the foam concrete slurry, remove the f...
