Nanometer water-saving pipe, water-saving device and manufacturing methods of two

Abstract

The invention discloses a nanometer water-saving pipe. The nanometer water-saving pipe is prepared by performing at least extrusion molding on modified plastic particles by an extruder and performing heating and inflation for expansion, and nanometer-level water-seepage apertures are formed on the wall of the nanometer water-saving pipe. The modified plastic particles comprise the compositions in percent by weight: 40%-60% of polypropylene, 10%-15% of nanometer calcium carbonate, 12%-15% of white carbon black, 1%-5% of a water permeating agent, 5%-15% of mica particles, 2%-10% of an anti-oxidant, 2%-5% of a stabilizer, and 2%-5% of petroleum resin. The above materials are mixed and granulated for forming the modified plastic particles. The manufacturing method of the water-saving pipe comprises: preparing the modified plastic particles, performing extrusion molding, heating, inflating for expansion, and the like. The beneficial effects comprise that the walls of the nanometer water-saving pipe and a corresponding water-saving device have a plurality of nanometer-level water-seepage apertures, so that the nanometer water-saving pipe and the water-saving device can be buried underground for usage, the irrigation problem of crops is effectively solved, and also a large amount of water source is saved; and through controlling water pressure, the water seepage amount is controlled, so that the water content on the ground surface layer is extremely low, the breeding of crop insects is avoided, and the output and the quality of crops are improved.

Description

【Technical field】 [0001] The invention relates to the technical field of agricultural irrigation, in particular to a nanometer water-saving pipe, a nanometer water-saving device and a manufacturing method thereof. 【Background technique】 [0002] Subsurface irrigation is an irrigation method that uses the construction of underground pipelines to irrigate the field cultivation layer, and uses the capillary action in the soil to moisten the soil near the root zone of the crop from the bottom. Underground irrigation includes groundwater infiltration irrigation and underground infiltration irrigation. Among them, the infiltration irrigation technology has the advantages of no damage to the soil structure, low surface water content, less evaporation, basically no loss of water delivery, and uninterrupted water supply for trees, herbs, and food plants during the growth period. Guaranteeing the normal growth of various trees and plants, high water utilization rate, good irrigation e...

AI Technical Summary

Problems solved by technology

Guaranteeing the normal growth of various trees and plants, high water utilization rate, good irrigation effect and other advantages, therefore, is the future development direction of underground irrigation technology; however, infiltration irrigation technology has defects such as complicated construction and great difficulty. , fruit trees, greenhouses, urban green spaces, etc. are all flooded, causing a great waste of water resources. As a result, many new water-saving irrigation technologies have emerged, such as sprinkler irrigation, drip irrigation, micro-spraying, etc. These technologies still belong to above-ground irrigation. , in order for the plants to get sufficient water, the soil at the roots of the plants must be completely moistened, and this part of the water is easily lost or evaporated under the action of the external environment, which will still cause a waste of water resources, and at the same time make the water contain The inorganic salts deposited on the soil surface will harden the ground over time and will not benefit the growth of plants. In addition, the devices used in these irrigation technologies are complicated and troublesome to implement. Water pipes of tens of meters are used for long-distance transmission through water pumps of a certain power. etc. All the pipelines, nozzles, drippers, etc. used must be placed on the ground, which brings a lot of inconvenience in farming and requires frequent maintenance and management

Based on the above problems, people have improved the existing technologies such as drip irrigation and micro-spraying, such as irrigation products with double-layer membrane water-saving pipes with better underground irrigation effects. The double-layer membrane water-saving pipes can be used for underground irrigation, and the water-saving effect is better than Drip irrigation pipes, etc. However, its processing technology is complex and backward, and the quality of the double-layer membrane water-saving pipes produced is difficult to guarantee, and still cannot meet higher demands
