A plastic composite seepage irrigation pipe and its manufacturing method

Abstract

A plastic composite seepage irrigation pipe and its manufacturing method, comprising an inner pipe, the inner pipe is provided with a groove, the groove is provided with a water seepage hole, the outer surface of the inner pipe is wrapped with non-woven fabric, the A foam material layer is arranged on the outside of the non-woven fabric, the groove is arranged on the outer surface of the inner tube, and the groove extends along the length direction of the inner tube. The foam material layer is made of the following components by weight: 15-25 parts of HDPE, 75-85 parts of LLDPE, and 1-2 parts of foaming agent. The method for manufacturing the plastic composite irrigation pipe includes an inner pipe extrusion molding step and a post-processing step, and the post-processing step includes punching holes in the formed inner pipe, and then wrapping a non-woven fabric around the inner pipe ; The inner tube after winding the non-woven fabric is coated with foaming material through an extruder, and the coated inner tube passes through a hot water tank to make the coated material fully foamed, and then the inner tube is cooled. The manufacturing cost is low, the process is simple, and the uniformity of water seepage is good, the anti-blocking ability is strong, and the service life is long.

Description

technical field [0001] The invention relates to the manufacture of a seepage irrigation pipe, in particular to a plastic composite seepage irrigation pipe and a manufacturing method thereof. Background technique [0002] Through the popularization and application of infiltration irrigation pipes in recent years, people have realized the benefits of using infiltration irrigation pipes. The use of infiltration irrigation can reduce soil compaction, increase land air permeability and help plants grow, and use infiltration irrigation to cover the surface of the land with plastic film and save water. The effect is obvious. The infiltration irrigation method saves resources and manpower, and the surface irrigation method needs to lay micro-irrigation materials once a year, which is not conducive to environmental protection by wasting manpower and materials. If the plants that can be planted by the infiltration irrigation method adopt the infiltration irrigation technology, the pro...

Problems solved by technology

During the production process of rubber and plastic irrigation pipes, the rubber has a strong odor. The rubber is water-swellable and easy to age. It is easy to be blocked in long-term use, which seriously affects the use effect of the product and the use length is limited.

The manufacturing equipment of rubber and plastic irrigation pipes is expensive, and the production efficiency of low-priced equipment is low, energy consumption is high, and product quality is not guaranteed.

There is little water seepage in the trace seepage irrigation belt, and the seepage volume is not easy to adjust
