Embodiment 1

[0029] Example 1 A special copper root remover for underground drip irrigation, which consists of the following components in weight percentage (kg / kg): 41.7% injection molding grade high-density polyethylene (HDPE), 20% low-density polyethylene (LDPE), 25% % high-voltage linear low-density polyethylene (LLDPE), 0.3% biological aging inhibitor, 9% copper powder and 4% masterbatch.

[0030] The production method of the special copper root-removing agent for underground drip irrigation comprises the following steps:

[0031] (1) Weigh each component according to the proportion;

[0032] (2) Put injection-grade high-density polyethylene, low-density polyethylene, high-voltage linear low-density polyethylene, biological aging inhibitors, copper powder and color masterbatch into a mixer and mix evenly to obtain a mixture.

[0033] (3) Put the mixture into the barrel, heat and plasticize in the injection molding machine, close the mold, inject, hold the pressure, cool and set ...

Embodiment 2

[0034] Example 2 A special copper root remover for underground drip irrigation, which consists of the following components by weight percentage (kg / kg): 45% injection molding grade high-density polyethylene (HDPE), 20% low-density polyethylene (LDPE), 23.75 % high-voltage linear low-density polyethylene (LLDPE), 0.25% biological aging inhibitor, 8% copper powder and 3% masterbatch.

[0035] The production method of the special copper root-removing agent for underground drip irrigation is the same as Example 1 .

Embodiment 3

[0036] Example 3 A special copper root remover for underground drip irrigation, which consists of the following components in weight percentage (kg / kg): 40% injection molding grade high-density polyethylene (HDPE), 20% low-density polyethylene (LDPE), 25% % high-voltage linear low-density polyethylene (LLDPE), 0.3% biological aging inhibitor, 10% copper powder and 4.7% masterbatch.

[0037] The production method of the special copper root-removing agent for underground drip irrigation is the same as Example 1 .

Abstract

The present invention relates to a special cooper root removing agent for underground drip irrigation. The special cooper root removing agent comprises the following components, by weight, 40-50% of injection molding grade high density polyethylene, 15-20% of low density polyethylene, 18-25% of high pressure linear low density polyethylene, 0.25-0.3% of a biological aging inhibitor, 8-10% of copper powder and 3-5% of color masterbatch. The present invention further discloses a production method for the root removing agent. The finished product has excellent performances of root system intrusion blockage resistance, fungal accumulation blockage resistance, oxidation aging resistance and the like so as to provide far-reaching theoretical guidance and practical significances for promotion of China's underground drip irrigation technology researches and product industrialization developments, especially for containment of ecological environment deterioration in northwest drought areas and effective water source utilization, and achievement of sustainable economic and social development.

Description

technical field [0001] The invention relates to the technical field of underground drip irrigation, in particular to a special copper root-removing agent for underground drip irrigation and a production method thereof. Background technique [0002] Plant root invasion is one of the important reasons for the clogging of underground drip irrigation emitters, which directly affects the normal operation and promotion of the underground drip irrigation system. Many experts at home and abroad have researched and discussed this problem, and put forward some methods and measures to solve this problem, including changing the process to produce special drippers for underground drip irrigation to prevent root invasion. head, but its production process is complicated and the cost is too high, so it has not been widely used. [0003] Scientific research shows that a variety of heavy metals have toxic effects on crops, especially the root system. When the content of heavy metals exceeds ...
