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
One, technical field
The present invention relates to a kind of material that is used for permeation filtration, particularly a kind of permeation filtration material that utilizes active carbon and polymer binder to make.The invention still further relates to this preparation methods and purposes.
Two, background technology
Particularly the northern area lack of water is serious in China most of area, and farmland irrigation water is very nervous, therefore necessary development water-saving irrigation technique.Infiltrating irrigation is referred to as subsurface irrigation again, is a kind of effective water-saving irrigation technique.
At the end of the seventies, the tile infiltration irrigation technology once under the assistance of the Chinese Academy of Sciences, was tested in the Wanrong County, Shanxi Province, but because sedimentation, to tile is stopped up, test is counted out.The nineties, the Yuncheng Prefecture, Shanxi Province has carried out plastic tube again and has pricked hole infiltration irrigation technology popularization, but this technology does not still fundamentally solve blockage problem.
The form of stopping up generally has four kinds, and the one, silt refluxes and deposits, and the silt that deposits in plastic tube not only stops up apopore, and stops up delivery pipe branch and water delivery hollow billet; The 2nd, it is improper to prick the hole instrument, pricks plastics retraction behind the hole; The 3rd, the contaminant filter of irrigation water is unclean, enters the pipeline plug-hole; The 4th, crop fibrous root growth penetrates in the hole and stops up.According to the investigation result statistics, plastic tube is pricked the hole filtration irrigation device and at wheatland 2-3 is installed, and crosses water 6-10 time, and apopore stopped up 11.71-80%, installed 2 years in the cotton field, cross water 4 times, obstruction reaches 35%, in the orchard 4-5 is installed, crosses water 13-15 time, obstruction reaches 18-34%.In these stopped up, sedimentation accounted for 32.7%, and impurity and fibrous root stop up and account for 36.7%, and the plastics retraction accounts for 30.6%.
Because plastic tube is pricked the hole infiltration irrigation technology and is not fundamentally solved blockage problem, makes people produce suspection to the popularization and the use of this technology.
In addition, it is narrower that plastic tube bundle hole filtration irrigation device also exists plastic tube bundle hole pore diameter range, and the hole in different apertures is difficult to strict processing and distinguishes, and can not play compensating action; Hollow billet is difficult to prolong, and maximum installation length only reaches 40-50 rice; Need than the long arm and the person in charge, cost increases, and defectives such as inconvenient, maintenance difficult, life-span weak point are installed.
Three, summary of the invention
The purpose of this invention is to provide a kind of novel permeation filtration material, this material is applied in the infiltrating irrigation system, can solve the blockage problem of infiltrating irrigation system up hill and dale.
This permeation filtration preparation methods is provided, and then is another object of the present invention.
Purpose of the present invention also aims to provide other purposes of this permeation filtration material.
Permeation filtration material of the present invention is that the material by following weight percentage is mixed and made into:
Active carbon 58-73% vinyl acetate co-polymer 8-12%
Polypropylene 15-30% molybdenum 0-0.5%
Wherein, active carbon is as the aggregate of permeation filtration material, and vinyl acetate co-polymer and polypropylene are the adhesives of material, and molybdenum then is to be immersed in the active carbon to use.
The concrete preparation method of permeation filtration material of the present invention is:
At first in the aqueous solution, metal molybdenum is impregnated in the active carbon, again the active carbon drying that is impregnated with molybdenum; Then dry activated carbon and powdery vinyl acetate co-polymer and polypropylene are mixed, afterwards mixture are heated, make vinyl acetate co-polymer and polypropylene fusion after, insert in the mould, compress, at last with after the mold cools down, the demoulding obtains the permeation filtration material of moulding.
Wherein, vinyl acetate co-polymer and polypropylene require to be crushed to the 30-60 order earlier, mix with active carbon again.
The temperature of mixture heating and melting should be controlled between 80-120 ℃, so that the softening bonding of polymer substance gets final product, the too high meeting of temperature is smoldered, and influences product.
According to the difference of mold shape, can make forming shape to the permeation filtration material and use.
The permeation filtration material that the present invention makes promptly can be applied in the infiltrating irrigation system, uses as the infiltrating irrigation head, can also be used to purify air and purification of water quality.
When making the permeation filtration material, can add a spot of metal molybdenum, also can not add molybdenum.The little metal molybdenum that adds can be used to remove airborne formaldehyde, also can increase the micro-molybdenum in the water, increases water quality.
Permeation filtration material of the present invention is made into novel infiltrating irrigation head, is applied in the infiltrating irrigation system, has solved the blockage problem of infiltrating irrigation, and the infiltration irrigation technology large tracts of land is promoted becomes possibility.And filtering material of the present invention is embedded in the soil not water funkly, is not afraid of and macerates, and is not afraid of chemical attack, and long service life is never stopped up.
The infiltrating irrigation head of making of the permeation filtration material can be divided into multiple model by going out flow rate, makes long hollow billet infiltration evenly, and infiltrating irrigation is compensatory good.Infiltrating irrigation head of the present invention also has quick for installation, and dismounting arbitrarily, and is easy to maintenance, adaptable advantage.
Permeation filtration material of the present invention is used for air cleaning, can remove airborne pernicious gas, reaches the purpose that purifies air, and particularly for removing airborne formaldehyde special-effect is arranged.
Permeation filtration material of the present invention is used for purification of water quality, can make reuse of wastewater, particularly removes harmful substances such as arsenic in the water, sulphur, lead.The present invention can also be used to drink water purification.Permeation filtration material of the present invention can filter out the solid particle more than 1 millimicron when purifying waste water.
