Abstract
The invention relates to a copper filter material, wherein said copper material is distributed with filter micro holes that alternatively arranged; the micro hole is formed by using diluted acid to dissolve the other metals of alloy copper. The invention uses copper as base, without corrosion, with better filter and purification properties, which can filter any water, as the medical waste water, etc. The inventive method is simple.
Description
Technical field
The present invention relates to a kind of preparation method of copper filtering material, copper filtering material is mainly as water purification material.
Background technology
Filtering material has a variety of, and Web materials, orifice plate material, cellular material are arranged, and also has filter paper etc., product material difference, structure difference, and performance is different, especially filtration, purifying property.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of brand-new copper filtering material, advantages of simple, easy to implement.
Copper filtering material of the present invention is distributed with filtering holes on its copper material.
Filtering holes is random and is staggered, and preferably micropore is made other metal stripping wherein through diluted acid by alloyed copper, stays micropore after other metal stripping, forms filtering holes.
Advantages of simple, preparation method easy to implement is as follows:
With copper and other metal bigger than its activity, as zinc, tin, lead, cadmium etc., be mixed and made into alloy, (be brass as ormolu, existing ormolu has 59 bronze medals, 69 bronze medals etc.), signal bronze, Pot metal, copper be every alloy etc., with acid other metal stripping is made then.Other dissolving metal just stays hole and forms filtering holes on copper alloy in acid (diluted acid), filtering holes is fine and closely woven evenly, and is crisscross.
According to metallic element activity command table, elemental copper can not be dissolved by diluted acid, many aqueous solution with hydrochloric acid or sulfuric acid, the volume ratio of acid and water is with 1: (500～1000) are suitable, best 1: (700～900), and the stronger metallic element of activity, all can be dissolved as zinc, tin, lead, chromium etc. by diluted acid.The copper alloy that will contain metal proportionings such as certain zinc, tin, lead, chromium soaks with certain density diluted acid, can be with the activity in the copper alloy stronger dissolving metal, and remaining copper billet with filtering micropore forms copper filtering material.
By the copper alloy that the control different content is formed, can obtain the copper filtering material of different filtering holes.The bigger filtering material of filtering holes can be selected the less copper alloy of copper content for use if desired; The less filtering material of filtering holes can be selected the bigger copper alloy of copper content for use if desired.
Among the present invention, the sour dissolving-out technology of the making of alloy and metal is ripe existing routine techniques, directly uses to get final product, and does not belong to creation of the present invention, repeats no more.
Copper filtering material of the present invention, based on copper, non-corroding, pollution-free, filter, purifying property is good, can be used for filtering the water of different quality, as be used for filtering the bacterium and the virus of medical waste water, or the salinity in the filtering sea, underground water, make pure water etc., also can be used for the filtration of others.Preparation method of the present invention is simple, ingenious, reasonable, implements easily.
