Abstract
The invention relates to a metallic filter membrane which can be used in flat filtration, cylinder filtration and folded filtration, etc. Said preparing method uses following materials: nickel, titanium, chrome, stainless steel, molybdenum, cobalt, iron, and copper, etc, that using the powder of one said material or the alloy powder to be mixed with adhesive to be plated on the frameworks (alloy porous base band or spongy base band with same characters of powder) to be sintered. The invention can prepare the filter membrane whose diameter in 0.1 nanometers to 5 micrometers according to the different granularities of powder, with the characters of high-temperature resistance, acid alkali resistance, large flux, small volume, and long service life.
Description
Technical field
The present invention relates to a kind of novel metal filtration film and preparation method thereof.
Background technology
At present, film is divided into organic film and inoranic membrane. and organic film in the market mostly is cellulose acetate film class, polyamide, the polyethers fluorine, the filter membrane of materials such as TPO, it is poor to exist temperature tolerance, mechanical strength is low, be not easy to clean, the life-span is short, repeat usage is low, mostly is disposable.
In recent years, along with membrane separation technique and application and development thereof, service condition to film has proposed more and more higher requirement, the catalysis of many films is reflected requirement and is carried out under hundreds of degree centigrade, and the diffusion barrier that is used for food and biological products also requires to have high-temperature steam, repeatedly cleaning and still can keep the constant characteristic of separation property. inoranic membrane more and more comes into one's own
Inorganic separating film comprises ceramic membrane, micropore glass, metal film and Carbon Molecular Sieve Membrane.Though they have good stable, high temperature resistant, acid and alkali-resistance, anti-erosion, anti-oxidant, advantage such as mechanical strength is high, the aperture is even, the flux area is big, volume is little, reproducibility is strong, but ubiquity thickness is thicker, can not fold, under the situation of same apertures, flux, overall volume is big and manufacturing process is complicated, technical merit requires height, and applicable surface is narrow, price is expensive especially.
Authorizing a kind of application number on State Intellectual Property Office's patent gazette on June 1st, 2005 is 99802139 " giving the method for the foil plated film of being made up of nickel or nickel alloy " patent of invention, its adopts method at sputter layer of metal compound on the vacuum foil when giving the foil plated film, the operating point is by in the constant boundary that remains on regulation, foil is determined, and does thermo-contact with hot cushion.The plated film of foil is even, but coating film thickness is thicker, can not fold, use inconvenience.
Summary of the invention:
In order to overcome the deficiencies in the prior art, the invention provides a kind ofly can fold, high temperature resistant, acid and alkali-resistance, novel metal filtration film that flux is big and preparation method thereof.
The object of the present invention is achieved like this:
The present invention, it is to be coated on according to a certain percentage on certain stephanoporate framework by metal dust and adhesive, makes by high temperature sintering then.
The method for preparing metal filtration film of the present invention, realize according to the following step:
1) metal material with a kind of porous rolls by roller, and for thin porous, thickness is 0.05mm-1mm.
2) with granular metal dust and adhesive in 100: ratio (1-5) (i.e. the adhesive of 100 parts of metal dusts and 1-5 part) evenly stirs, and is coated on the both sides of porous metals.
3) slice, thin piece after will being coated with again is rolled into the sheet metal of 0-5 millimeter.
4) high temperature of the sheet metal that will roll by 100 degrees centigrade-1400 degrees centigrade carries out sintering, makes metal filtration film.
5),, can make the metal filtration film of 0.1 nanometer-5 micron according to the difference of powder size by the method.
Wherein metal dust is to be coated on the foaming nickel with sedimental form, compare with traditional porous sintered metal filter material, the present invention is owing to adopted above-mentioned technology, not only film is thin, collapsible but also volume is little, cost is low, the life-span is long, easy-formation, filtration flux height, pressure drop is less, backwashing period is long, and repercussion effect is better.
