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...

Abstract

An inorganic micro -irrigation pipe and the mold used and the method of making a micro -irrigation tube with this mold, including the hollow tube, and the tube wall is set with at least one evenly distributed bubble.There is a hole with a diameter of 10 to 600nm between the walls.The tubular production raw materials include fiber, silicate cement and water, and the production materials of the tube body are also added with foaming agents.The ingredients of the foam concrete used in the present invention are close to the soil composition, and the price of the component used is cheap, durable, and water -saving effect can reach the level of trace irrigation and moisturizing.EssenceAt the same time, the water -saving effect is comparable to the trace irrigation head and micro -moisturizing tube, which is 60-80%more than drip irrigation water.

Description

technical field [0001] The invention relates to a water-saving irrigation device, in particular to an inorganic micro-irrigation pipe, a mould, and a method for manufacturing the micro-irrigation pipe with the mould. Background technique [0002] With the continuous growth of the world population, the fresh water resources on the earth are becoming more and more scarce. my country's total water resources are 280 million m 3 , ranking sixth in the world, but my country's population accounts for more than one-fifth of the world's total population, and the distribution of my country's water resources in time and space is still extremely uneven, with more in the south and less in the north. Agricultural irrigation water consumption accounts for more than 60% of the total water consumption of various industries, and it is a veritable major water user. Therefore, water-saving irrigation has developed from flood irrigation, sprinkler irrigation, drip irrigation, and micro-drip ir...
