Embodiment 1

[0028] Weigh 60 g of activated carbon, 8 g of vinyl acetate copolymer, 28 g of polypropylene, and 0.05 g of gold-layer molybdenum. Among them, the vinyl acetate copolymer and polypropylene are powders that pass 60 meshes. Put the activated carbon into the water, add the gold layer molybdenum, so that the metal molybdenum is completely immersed in the activated carbon, remove the water liquid, dry the activated carbon impregnated with the metal molybdenum, mix it with vinyl acetate copolymer and polypropylene powder thoroughly, and heat it. After the temperature is raised to about 100°C, the polymer is softened and bonded, the mixture is filled into the heated mold, and pressure is applied to fully compress the material. After the compressed mold is cooled, the molded material is removed from the mold Unload it. The made permeable filter material is then cut, polished and modified into a product. According to needs, the product can also be drilled or welded with plastic parts.

Embodiment 2

[0030] figure 1 It is an infiltration irrigation head made of permeable filter material. In the figure, a circular groove is drilled in the center of the cylindrical permeable filter material 1, and a plastic joint 2 is welded in the groove to form an infiltration irrigation head.

Embodiment 3

[0032] figure 2 It is a water filter made of permeable filter material. In the figure, the permeable filter material 1 is made into a hollow cylindrical shape, and the upper and lower ends are blocked. A core tube 5 is installed in the cavity 3 of the permeable filter material 1. A number of water outlets 4 are provided on 5, and the core tube 5 is connected with the water inlet 6 at the upper end of the permeable filter material 1. The water enters the core tube 5 from the water inlet 6 and flows into the cavity 3 through the water outlet 4, and is filtered by the permeable filter material 1 to obtain purified water.

Abstract

A percolating filtering material is prepared with active carbon as aggregate 58-73 wt%, copolymer of polyvinyl acetate 8-12 wt% and polypropylene 15-30 wt% as adhesive, and through mixing and hot pressing to form the said material. The material may have metal molybdenum added or not. The percolating filter material of the prsent invention is mainly used as infiltrating irrigation head of farm field infiltrating irrigation system and is not liable to be blocked. The material of the present invention may be used in air filter to eliminate formaldehyde and other harmful gases and in water filter to eliminate As, S, Pb and other harmful matters and 1 nm over solid particles.

Description

1. Technical Field [0001] The invention relates to a material for permeation filtration, in particular to a permeation filtration material made of activated carbon and a polymer binder. The invention also relates to the preparation method and use of the material. 2. Background technology [0002] Most areas of my country, especially the northern areas, suffer from severe water shortages, and irrigation water for farmland is very tight. Therefore, it is necessary to develop water-saving irrigation technologies. Infiltration irrigation, also known as underground irrigation, is an effective water-saving irrigation technology. [0003] In the late 1970s, Wanrong County, Shanxi Province, with the assistance of the Chinese Academy of Sciences, tried the tile tube infiltration irrigation technology, but due to sediment deposition, the tile tube was blocked and the test failed. In the 1990s, the plastic pipe hole infiltration irrigation technology was promoted in Yuncheng, Shanxi Provinc...
