Abstract
The present invention relates to a novel rare earth alloy functional material and is an ideal high efficiency functional material capable of removing various aquatic substances harmful to human bodies. The functional material is usually powdery or fibrous and can be widely used for treating water qualities with different requirements by being made into purifiers of different specifications or in different shapes. The method of the present invention has the advantages of convenient material obtainment and simple process due to the adoption of a smelting atomizing method; the present invention is a novel practical high-technology functional material.
Description
The present invention relates to a kind of alloy functional materials, be specifically related to a kind of rare earth alloy purifying functional-material.
At present, water purification handle materials such as most applied activated carbon, reverse osmosis membrane make a return journey dewater in harmful material, obtain certain effect, but desirable not enough.Along with the high speed development of industry, being on the rise of environmental pollution, the particularly severe contamination of water quality, tap water to the health threat of human body by the common concern of people institute.
U.S. Patent number 4,642,192,5,122,274,5,135,654 and 5,198,118 have disclosed a kind of platina (being called the KDF treatment media), are used for water treatment device, to remove anhydrate middle chlorine and other organism, heavy metal ion, and have elimination and suppress bacterial growth, functions such as balance water quality potential of hydrogen.The mechanism of action of platina in water treatment is the reaction of applying electrode chemistry redox, in electrode chemistry redox processes, zinc is anode, copper is negative electrode, particle and interparticle space are electrolyzer, and the unwanted impurity in the aqueous fluid is just taken on electrolytical role, when aqueous fluid with after platina contacts, promptly can produce micro-current, change the objectionable impurities in the water into harmless composition by electrolytic action.
Purpose of the present invention aims to provide a kind of rare earth alloy purifying functional-material.It can remove toxic substance in the water, heavy metal ion, fluorion, free chlorine, biological pollution material etc., and can prevent the secondary pollution in the water purification equipment.
Above-mentioned purpose of the present invention realizes in the following manner: a kind of rare earth alloy purifying functional-material, contain Zn 30-57%, Cu 28-65%, with be selected from a kind of La, the norium 5-15% of the norium of Ce or La or Ce, the norium of described La contains La 48-50%, Ce28-30%, Pr 1-3%, Nd 10-12%, Sm 3-4%, Eu 2-4%, the norium of Gd 1-3% and Y 1% and described Ce contains Ce 49-51%, La 26-28%, Pr 6-8%, Nd 11-12%, Eu 1-2%, Sm 1-2%, Gd 0.5-1% and Y 0.5-1%.
Purifying functional-material of the present invention can through water atomization or aerosolization method, obtain spherical powder material or irregular plate material by behind Zn, the Cu and rare earth element melting of intermediate frequency furnace with above-mentioned prescription, and its loose density is 1.0-2.0g/cm
3, granularity was 80 orders, yellow-green colour is nonpoisonous and tasteless.Also can be made into villus fiber shape material, to adapt to the requirement of different refining plants.
Advantage of the present invention is tangible, the novel alloy functional materials is except the purification function with above-mentioned platina, also because the chemical property of thulium is very active, form higher redox potential with the pairing of zinc, copper, the objectionable impurities that can more effective removal platina is difficult to remove such as fluorion etc.Simultaneously, the atomic structure of rare earth element has common feature, be that skin has 2 electronics, inferior skin has 8 electronics, their chemical property is all alike, and valency is generally positive 3 valencys, therefore, the alloy functional materials of the present invention that adopts above-mentioned selection component to constitute purifies the role and influence that character has equivalence to it.In addition, alloy of the present invention can adopt outside the copper, zinc of general industry purity, also can adopt the mixture of La and Ce, has reduced cost like this, and has not influenced its purification function.
The present invention is described in further detail below with reference to specific embodiment and application examples, among the embodiment unless stated otherwise outside, all adopt weight percentage.
The present invention adopts the method preparation of melting atomizing, can pass through intermediate frequency furnace, with zinc, copper and rare earth element by the prescription melting after, obtain the spherical powder material or obtain irregular plate material by the water atomization method or through the aerosolization method again, its loose density is 1.0-2.0g/cm
3, granularity was 80 orders, yellow-green colour is nonpoisonous and tasteless.Also can make fiber or fine hair shape material, to adapt to the requirement of different refining plants by melting liquid spray silk.
