Description
Technical field
The present invention relates to the zinc alloy field, relate in particular to the special-purpose zinc alloy of a kind of bathroom industry.
Background technology
Bathroom industry goods generally adopt pottery or copper as producing material, and both have good smooth effect, the convenient use.Ceramic sanitary ware products machinery intensity is high, and wear resistance, good corrosion resistance are used widely.But ceramic fragility is big, and shock-resistant ability is low, frangible.And along with the people's growth in the living standard, people also more and more pay attention to ecological environmental protection, especially to more paying close attention to our healthy comparatively serious impact of heavy metals factor.Copper is widely used in hot-water heating bathroom and other field as a kind of raw materials for production commonly used.But the bathroom product that general copper material is made contains lead usually; Plumbous effect one heavy metal species, its pollution and harm to environment and human body also exists always, when copper alloy containing lead is used in the sanitaryware; Can in production and use, influence HUMAN HEALTH, cause environmental pollution.In addition, compare with the price of other material copper higherly, as the bathroom material cost is increased with copper.It is big that zinc alloy material has intensity; Toughness is good; Characteristics such as easy coloring have the metal sense and the graceful material of copper simultaneously, and cost have bigger advantage than copper; Development Trend after the production of at present carrying out bathroom product with zinc alloy Alloy instead of Copper material has become, but the present zinc alloy of also not developing the special use of bathroom industry.
Summary of the invention
The objective of the invention is in order to overcome the deficiency of currently available products technology, provide that a kind of ductility is good, intensity is big, the special-purpose zinc alloy of the bathroom industry that foundry goods shrink ratio is little and polishing effect is good.
The present invention realizes through following technical scheme: the special-purpose zinc alloy of a kind of bathroom industry, and it is characterized in that: the weight percent content of described zinc alloy is formed as follows:
Aluminium 3.7-3.8%
Copper 0.002-0.005%
Magnesium 0.03-0.04%
All the other are zinc and other unavoidable impurities, and total impurities is not more than 0.1%.
The special-purpose zinc alloy of a kind of bathroom industry, it is characterized in that: the weight percent content of described zinc alloy is formed as follows:
Aluminium 3.7-3.8%
Copper 0.002-0.005%
Magnesium 0.03-0.04%
And or mishmetal at least a, the content of said titanium is respectively: titanium 0.00025-0.0005%, the weight percent content of described mishmetal are 0.0005-0.00075%.
All the other are zinc and other unavoidable impurities, and total impurities is not more than 0.1%.
The present invention further is improved as: described Zinc material should select for use purity to make raw material greater than 99.995% high purity zinc.
The present invention further is improved as: content by weight percentage in the described impurity: plumbous≤0.003%, iron≤0.03%, cadmium≤0.003%, tin≤0.001%.
A kind of bathroom industry of the present invention special-purpose zinc alloy is to reach the effect of reinforcement through adding alloying elements such as an amount of copper, aluminium, magnesium, titanium, rare earth, and the action effect that adds element is following:
Copper: the effect of copper mainly shows solution strengthening, and the copper solid solution of trace causes lattice distortion in zinc, to the slippage generation obstruction of dislocation, thereby increases hardness of alloy and intensity.Simultaneously, adding suitable copper can improve the wear resistance of alloy and reduce intergranular corrosion.Therefore, the copper content of confirming according to experiment the present invention is 0.002-0.005%.
Aluminium: add the oxidation that Trace Aluminum can reduce zinc in the zinc; Improve the casting surface quality, and suppress the formation of TeZn7 frangible compounds, Trace Aluminum can crystal grain thinning simultaneously; Improve the tensile strength and the plasticity of zinc, the corrosion resistance nature that improves alloy is also had certain effect.Test shows: the mobile peak that when aluminium content 5 %, reaches; Dropped to minimum value at 3.0% o'clock.Shock strength reaches peak at aluminum content 3.5%; Dropped to minimum value at 6% o'clock.Aluminum content surpasses 4.3%, and alloy becomes fragile.Aluminum content is lower than specialized range, causes thin-wall part to fill the type difficulty, and casting postcooling disruptive possibility is arranged.The aluminium content of confirming according to experiment the present invention is 3.7-3.8%.
Magnesium: ratio magnesium is greater than the effect that can play raising at 0.03% o'clock to alloy strength in zinc alloy for magnesium, and magnesium content is greater than 0.08% o'clock, can produce hot-short, toughness descends, mobile decline, does not utilize the completion of draw down operation.Therefore the content of the magnesium confirmed of the present invention is 0.03-0.04%.
Titanium: in zinc alloy, add a spot of titanium, significant feature is a crystal grain thinning, particularly in containing the higher zinc alloy of aluminium, adds a spot of titanium, improves its low-temperature impact toughness thereby can significantly improve crystalline state.The grain refining of zinc alloy also embodies intensity increase and hardness and improves on physical and chemical index, improve the over-all properties of alloy.The addition of titanium of the present invention is 0.00025-0.0005%.
Rare earth: rare earth is the good grain-refining agent of zinc alloy, in zinc alloy, adds the rare earth of trace, but except crystal grain thinning; The deleterious effect of ferro element be can also eliminate, thereby the intensity and the plasticity of zinc alloy, low excessively content of rare earth improved zinc alloy; When less than 0.0000l%, act on extremely small, but when greater than 0.0001% the time; It is not obvious that the continuation of zinc alloy intensity is risen, and increased material cost, so the content of rare earth that the present invention confirms is 0.0005-0.00075%.
Zinc alloy intensity provided by the invention is big, hardness is high, and foundry goods shrink ratio is little, and polishing effect is good, low price, and alternative traditional copper and pottery are used to make fields such as bathroom product.
