Abstract

The invention provides a microporous permeable pipe and is prepared with the following steps: (1) clean rubber and plastics is separately crushed into powder of 45 to 70mm and 55 to 75 portion of rubber and 20 to 40 portion of plastics are mixed together by weight; (2) the mixture is added with 2 to 4 portion of oil resin, 0.4 to o.6 portion of foaming agent, 0.4 to 0.6 portion of heat stabilizingagent and 0.6 to 1.4 portion of ethylene vinyl acetate copolymer by weight and then is granulated after stirring for 20 to 40min; (3) particle from the step (2) is squeezed and molded. Irregular bending Millipores are distributed on the wall of the realized Millipore soakaway trench from inward to outward. Density is 40 to 110kg / m<3>, thickness of the trench wall is 1.5 to 3mm, working pressure is 0.1 to 0.5kg, water percolating capacity is 1.4 to 4.2kg / min, and water percolating effective length is 40 to 80m. When in work, the microporous permeable pipe of the invention can coordinate the ratio of water, vapor and heat in soil and cannot lead to clotting of soil as well as water loss and soil erosion, moreover, secondary salinization of soil can be inhibited.

Description

【Technical field】 [0001] The invention relates to the field of irrigation and fertilization devices for agriculture and gardens, in particular to a microporous water seepage pipe. 【Background technique】 [0002] my country is seriously short of water resources. According to statistics, my country's per capita water resources are only equivalent to 1 / 4 of the world's per capita water resources. Therefore, various fields of social life, especially the development of water-saving products in the field of agriculture and garden irrigation, have always been widely concerned. [0003] Drip irrigation technology is widely used in my country at present, and generally nylon or PVC pipes are used as water delivery pipes, and holes or incisions are drilled or cut on the pipe wall as water outlets. However, drilling or cutting will destroy the strength of the pipe. When the pipe is squeezed, the opening is easily deformed, which affects the circulation of the liquid in the pipe. Drip ...
