Problems solved by technology

[0004] During the promotion and application, we found that the double-layer structure made the production process of the micro-moisture tube more complicated, and the production cost increased
At the same time, the composite pipe made of two (layers) of different materials also brings some troubles for future recycling

Embodiment 1

[0033] Production of B-type micro-moisture tube with small water output

[0034] Weigh 400 kilograms of light calcium carbonate with a fineness of 5000 meshes, add 12 kilograms of AEO-7, put it into a high-speed mixer, and stir for 15 minutes. Drop into 588 kilograms of powdered low-density polyethylene again after shutting down, and mix at high speed for 20 minutes. Put the mixed material into the granulator to form filled granules, and set aside.

[0035]Put the filling granules into the pipe making machine, and make B-type micro-moisture pipe through extrusion molding, sizing cooling, drawing and stretching, and surfactant extraction. The outer diameter of the pipe is 16mm, the wall thickness is 1.0mm, and the outer wall is smooth and tidy. Non-porous, similar to normal plastic hose. After the tube is filled with water, the tube wall is wet as a whole and slowly releases water outward. Wherever the pipes are laid, the land there will be gradually moistened with water. A...

[0037] Production of B-type micro-moisture tube with large water output

[0038] Weigh 550 kg of silica filler with a fineness of 3000 mesh, add 17 kg of AEO-7, put it into a high-speed mixer, and stir for 15 minutes. Put into 433 kilograms of powdery low-density polyethylene again after shutting down, and mix at high speed for 20 minutes. Put the mixed material into the granulator to form filled granules, and set aside.

[0039] Put the filling granules into the pipe making machine, and make B-type micro-moisture pipe through extrusion molding, sizing cooling, drawing and stretching, and surfactant extraction. The outer diameter of the pipe is 16mm, the wall thickness is 0.5mm, and the outer wall is smooth and tidy. Non-porous, similar to normal plastic hose. After the tube is filled with water, the tube wall is wet as a whole and slowly releases water outward. Wherever the pipes are laid, the land there will be gradually moistened with water. After testing, the water out...

[0041] Type B micro-running pipe for ground irrigation

[0042] Cut the B-type micro-moisture tubes treated with anti-light aging into tube sections as long as the ridges, and lay one piece on each ridge next to the crops on the ridge. One end of the tube was closed with a plug. One end is connected to the water pipe with a tee, and multiple B-type micro-moisture pipes are connected to the water pipes one by one to form a comb-shaped irrigation network. After the water pipe is connected to the water source, water enters the B-type micro-moisture pipe. The B-type micro-moist tube wall is wet, slowly releases water to the soil, and forms a semicircular wetting body in the soil of the root zone of the crop. The soil moisture content in the wetting body is high, so that the roots in the wetting body can absorb sufficient water. , well irrigated.

[0043] Since the pipes are laid on the ground and are directly exposed to sunlight and air, the evaporation caused by light, heat and...

Abstract

The invention provides a B-type moistube manufactured through a one-step forming method, a manufacturing method of the B-type moistube and application of the B-type moistube. An existing moistube is a novel irrigation water supply device which is manufactured with a functional new material semi-permeable membrane serving as a core material. A huge number of microporous networks are distributed on the semi-permeable membrane, water outlet network points appear on the whole membrane wall after the membrane is filled with water, moisture can be slowly released out of the membrane, the amount of the released water depends on the energy difference of the two sides of the membrane, the larger the energy difference is, the larger the amount of the released water is, and therefore the amount of the released water can be controlled by adjusting pressure in the membrane. According to the B-type moistube for agricultural irrigation, tube bodies formed by the tube wall are equal in diameter, the tube wall is a thick-wall single-layer tube wall, the tube body is the moistube wall which is provided with the capillary network and is produced through once extrusion forming conducted by an extrusion tube making machine and corresponding auxiliary machines and through extraction conducted by an extraction machine. The B-type moistube is used for agricultural water-saving type irrigation.

Description

technical field [0001] The invention relates to a tubular water feeder for agricultural irrigation and a manufacturing method of the tube, which is also an improvement on the previous traditional micro-moisture tube. Background technique [0002] The micro-moisture tube is an irrigation device, and its characteristics are described in detail in many Chinese patents including "micro-moisture" or "solid water" as keywords such as 201010530596.8 and 2011100547503. This product is a new type of irrigation water feeder made of functional new material semi-permeable membrane as the core material. Since a large number of micropore networks are distributed on the semi-permeable membrane wall, after the membrane is filled with water, the membrane wall is a water outlet, which can slowly release water to the outside of the membrane. The amount of released water depends on the energy difference on both sides of the membrane. The greater the difference, the greater the water output, th...
