AI Technical Summary

Problems solved by technology

Among them, drip irrigation accounts for 80%. As an important drip pipe in the drip irrigation system, the drip irrigation belt is exposed to the surface and exposed to the sun for a long time. The phenomenon of fracture affects normal irrigation, and it will take a lot of work and time to repair or replace it, especially in Xinjiang where the high temperature continues in summer, and Xinjiang is an intensive large-scale agricultural production, the above problems are particularly prominent
To solve the above problems, it is necessary to increase the amount of additives in the raw materials of the drip irrigation tape, which leads to an increase in production costs, so that the performance and cost of the drip irrigation tape cannot be balanced
Secondly, due to the low tensile strength of the drip irrigation belt, the drip hole size is unstable during use, resulting in uneven flow

Abstract

The present invention relates to a nano material modified drip irrigation band. It is composed of (by weight portion) 60-100 portions of polyethylene resin, 5-40 portions of nano-grade calcium carbonate modification material and 0.01-8 portions of working adjuvant.

Description

technical field [0001] The invention relates to water-saving irrigation equipment, in particular to nano-material modified drip irrigation belts. Background technique [0002] Due to global climate conditions and population growth, the contradiction between global water supply and demand is increasing. my country is a country with severe water shortage. Among the total water consumption, irrigation water accounts for 70%, and irrigation water conservation plays a pivotal role in water conservation. Xinjiang is located in the hinterland of Eurasia, with large temperature difference between day and night, dry climate and little rain, annual precipitation is only 12.2-140mm, the lowest area is only 10mm, water-saving irrigation is particularly important, so a series of sprinkler irrigation, Water-saving equipment such as micro-irrigation and under-film drip irrigation. Among them, drip irrigation accounts for 80%. As an important drip pipe in the drip irrigation system, the d...
