Abstract

The present invention relates to an alloy material used for producing nutritional type clean drinking water, which is characterized in that a Cu-Zn-Se ternary alloy is produced by an ordinary method, and a multi-component alloy is formed by adding the elements including Si, Ca, Ae, Sn, Ag, Ti, Ni and Mg to the Cu-Zn-Se ternary alloy. After water passes through the alloy material of the present invention, not only can harmful substances in water be reduced and even removed, but also human body vital trace elements, such as selenium, are formed by dissolving in the clean drinking water; therefore, the drinking water with nutrients and health care value can be obtained by adopting the alloy material of the present invention.

Description

A kind of alloy material that is used for purifying nutritive drinking water

The invention belongs to the alloy material technology, a kind of material that is used for the Cu-Zn-Se ternary alloy of clean tap water for the basis of more specifically saying so.

At present, the material that is used for the tap water cleaning mainly contains activated carbon and ion exchange resin two big classes.Activated carbon relies on the surface adsorption reaction, remove chlorion and niff in the tap water, but can't remove toxic impurities such as lead in the water, mercury, and after filtering certain water gaging, will reach capacity and lose clean filteration, the water treating device of being made by the clean material of activated carbon of general family expenses can only filter 200 usually and promptly reach capacity after adding Cang Shui, for this reason, must change the water treating device fuse one time at about two months.The ion exchangeable resin, ion to be removed in ion in the application resin and the water carries out chemical reaction, and to reduce even to remove unnecessary composition in the water, its effect is more single, and the life-span is also shorter.

United States Patent (USP) 5,833,859; 5,599,454 have invented a kind of material of the clean usefulness of water of Cu-Zn binary alloy.Use this powdered alloy, can be simultaneously remove chlorion in anhydrating and each heavy metal species such as copper, mercury, iron, calcium etc., the more important thing is this metal-powder remove anhydrate in the process of impurity be by the redox chemistry reaction, therefore its life-span is very long, experimental results show that, this metal-powder is used for clean tap water, and its life-span is 10-100 a times of activated carbon.In addition, the Cu-Zn alloy both can be handled normal temps water, also can be used to handle the hot water that surpasses more than 50 ℃, and activated carbon can only be used for handling the tap water below 40 ℃, and range of application is just wide like this; In addition, the Cu-Zn alloy has a small amount of dissolved Zn and Cu ion in water, but they do not have big deleterious effect to human body, and is therefore favourable than other metal alloy.

The objective of the invention is to propose a kind of objectionable impurities that not only can reduce even remove in the water, and can produce alloy material human body beneficial's element.

Realize the main technical scheme of the object of the invention: the employing usual method is produced the material based on the Cu-Zn-Se ternary alloy.

Alloying element of the present invention comprises Cu, Zn, and Se, ternary alloy can be represented by the formula: Cu _x-Zn _y-Se _z, x, y, z is atomic ratio, should satisfy following condition: o＜x＜1; O＜y＜1; O＜z＜0.3; X+y+z=1.

Cu-Zn-Se alloy of the present invention also can add and is selected from Si, Ca, Fe, Al, Sn, Ag, Ti, Ni, a kind of among the Mg.Two or more element, its add-on form the multi-element metal alloy less than 10% of alloying element gross weight sum.

Alloy of the present invention adopts the ordinary method preparation promptly to make ingot casting by vacuum melting, and then uses gas atomization or mechanical means and make and comprise powder, thin slice, particle, the shape of silk screen.

Major advantage of the present invention and effect: with Cu-Zn alloy phase ratio, can reduce in addition remove anhydrate in more detrimental impurity, what is more important is owing to contain selenium in the alloy, solubilized produces the elemental selenium of the nutritious value of human body in clean tap water.Selenium is one of trace element of the definite needed by human of the World Health Organization, a large amount of medical researches both at home and abroad confirm: human body lacks selenium can cause vitals dysfunction, appropriate supplement selenium has prevention and assisting therapy effect preferably to cancer, arteriosclerosis, hypertension, diabetes, liver and pancreas disease, therefore alloy of the present invention is used for clean tap water, can obtain having the tap water of health nutrient effect.

Further specify characteristics of the present invention below by specific examples.

Example 1-5

With Cu, Zn, the Se element is made ingot casting with different atomic ratios by usual method, and then the application gas atomization is prepared into 100 order powder.See Table 1.
