A kind of production method of conductive geotextile

Abstract

The invention relates to a production method, in particular to a method for producing conductive geotextile. The method for producing the conductive geotextile comprises the steps of raw material selection, raw material screening, drying, fusion, spinning, cross air blow cooling, airflow drafting, swinging, net laying, mixed even feeding of metal fibers, carbon fibers and other short fibers, ironing conducted by a hot roller, shaping conducted by a pre-needle machine, reinforcing shaping conducted by a first main needle machine, repair shaping conducted by a second main needle machine, cloth containing conducted by a cloth containing machine, trimming and rolling. The geotextile produced according to the method for producing the conductive geotextile has the protective performance, the isolating performance, the waterproof performance, the filtering performance and the like of traditional geotextile, further has the conductive characteristic and is a good electrode material. According to the method for producing the conductive geotextile, the production technology is stable, control over the thickness of a material is good, the control range of the puncture density is large and is 50 to 500 stitches / cm<2>, the controllable range of the permeability performance of the material is large and is (1.0-9.9)*(10<-1>-10<-3>)cm / s, the strength of the product is high, and the thickness reaches 20mm.

Description

Technical field [0001] The invention relates to a production method, more specifically, to a production method of conductive geotextile. Background technique [0002] Traditional geotextile production lines include filament geotextile production lines, short-filament geotextile production lines, various composite geotextile production lines, etc. The products produced by these geotextile production lines are used in engineering construction to protect, isolate, strengthen, and drain , Filter and other functions, belong to traditional craft products. [0003] At present, with the development of engineering construction in China, higher requirements are put forward for the construction material of geotextile. For example, by applying direct current in the wet soil, it will be found that the water in the soil flows from the anode to the cathode relative to the soil particles.

Problems solved by technology

[0003] At present, with the development of engineering construction in our country, higher requirements are put forward for the construction material of geotextile. For example, by applying direct current in wet soil, it will be found that the water in the soil flows from the anode to the cathode relative to the soil particles. This phenomenon is called electroosmosis. Electroosmosis technology is continuously applied in engineering construction and crop cultivation, such as purifying polluted soil by electrochemical means, electrodynamically transporting nutrients to the soil to promote crop growth, and electroosmosis is accelerating soil consolidation and improving crop growth. Reinforced soil technology has more outstanding advantages. At present, the electrodes used in electroosmosis are all metal electrodes, and metals are used as electrodes. The anode generally has corrosion problems and the cathode is easy to block.
