Abstract
The invention relates to an exclusive treatment for metal powder, which particularly belongs to a novel copper-based alloy powder and a manufacturing method thereof. The invention adopts the technical scheme that the formula composition includes the following components by the weight percentages: 1% to 15% of bismuth, 0.5% to 10% of tin, 0.3% to 15% of zinc and copper in balancing amount. The invention adopts the manufacturing method that the copper is put into a high-frequency smelting stove at first, then the tin, the bismuth and the zinc are put into the high-frequency smelting stove in sequence after melting, after all the components are melted and evenly mixed, poured into a filter, sprayed through a V-shaped spraying nozzle, pulverized into powder by high-pressure water flow and then dried. The invention has the advantages that because the copper-based alloy powder adopts the bismuth instead of the lead, the metal powder is unleaded, which is innocuous for the human body and pollution-free to the environment; therefore, the metal powder is an environment-friendly copper-based alloy powder.
Description
Technical field
The present invention relates to the special disposal of metal dust, especially belong to a kind of copper-base alloy powder and manufacture method thereof.
Technical background
The copper-base alloy powder of traditional manufacturing bush material is made up of copper, lead, tin, zinc (or phosphorus), owing to contain lead, toxic to human body, environment there is pollution.Regulation in European Union's " some harmful substance is used in restriction in electric, the electronic equipment ", from July 1st, 2006, the new electronics and the electrical equipment that devote market must not contain harmful substances such as lead.Simultaneously; along with people to improving day by day of environmental protection consciousness and self health requirements and popularizing of mechanization traffic, production and daily life instrument; people recognize the pollution to people and environment of refuse that various tool in use produced; people wish that the various parts of institute's tool using all are environmentally friendly machines; therefore, seeking lead in the copper-base alloy powder that a kind of nontoxic constituent element replaces traditional manufacturing bush material, to become development inevitable.
Summary of the invention
The object of the present invention is to provide a kind of copper-base alloy powder and manufacture method thereof of using bismuth, make the copper-base alloy powder of producing not contain harmful compositions such as lead.
The technical solution used in the present invention is that its prescription is formed and comprised bismuth, tin, zinc and copper; It is characterized in that: its prescription composition is by weight percentage: bismuth 1%, tin 0.5%, zinc 0.3%, surplus are copper; Or bismuth 15%, tin 10%, zinc 15%, surplus is a copper.
Its manufacture method is: earlier copper is put into high-frequency melting furnace, after the fusing, put into tin, bismuth, zinc more successively, after all melting and mixing, be poured in the filter bag, through the ejection of V-arrangement nozzle, and be ground into powder by High-Pressure Water, drying gets final product.
Usefulness of the present invention is: because this copper-base alloy powder replaces lead with bismuth, not leaded, to the human body nonhazardous, environmentally safe is a kind of environment-friendly type copper-base alloy powder.
The specific embodiment.
Be specific embodiments of the invention (in the enforcement of concrete scheme, can allow the impurity in the metal to exist) below.
Embodiment 1: copper is cut into pieces, bismuth, tin, zinc are cut into small pieces, get bismuth 3kg, tin 1.5kg, zinc 0.9kg, copper 294.6kg by the weight that its prescription is formed, amount to the material of 300kg.Earlier copper sheet is put in the high-frequency melting furnace, wait fusing after, put into block tin, bismuth piece, spelter successively, after all melting and mixing, be poured in the filter bag, through the ejection of V-arrangement nozzle, and be ground into powder by High-Pressure Water, drying gets final product.
Embodiment 2: copper is cut into pieces, bismuth, tin, zinc are cut into small pieces, get bismuth 45kg, tin 30kg, zinc 45kg, copper 180kg by the weight that its prescription is formed, amount to the material of 300kg.Earlier copper sheet is put in the high-frequency melting furnace, wait fusing after, put into block tin successively, bismuth piece, spelter after all melting and mixing, are poured in the filter bag, through the ejection of V-arrangement nozzle, and are ground into powder by High-Pressure Water, drying gets final product.
Embodiment 3: copper is cut into pieces, bismuth, tin, zinc are cut into small pieces, get bismuth 15kg, tin 15kg, zinc 15kg, copper 255kg by the weight that its prescription is formed, amount to the material of 300kg.Earlier copper sheet is put in the high-frequency melting furnace, wait fusing after, put into block tin successively, bismuth piece, spelter after all melting and mixing, are poured in the filter bag, through the ejection of V-arrangement nozzle, and are ground into powder by High-Pressure Water, drying gets final product.
