Summary of the invention
The objective of the invention is to overcome the deficiency that existing lead anode material exists, a kind of good electric conductivity that has is provided, the lead-aluminum composite anode plate preparation methods of mechanical property has preferably been arranged again.Another object of the present invention is to have solved lead-aluminium two metals interface to each other in conjunction with difficult point on engineering, and providing a kind of energy production to have high conductivity has the method for mechanical property lead-aluminum composite anode plate preferably again.
The present invention realizes by following technical scheme:
It is starting material with pure aluminum plate or aluminium alloy plate, pure lead or pb-ag alloy and copper conducting beam.
Its manufacturing step is: (1) cuts aluminium sheet 1, and its thickness is 0.5-5.0mm, and length is 120-2000mm, and width is 90-1000mm; (2) aluminium sheet 1 is carried out acid etching, remove oxide film, then at aluminium sheet 1 surface plating one deck Zn or Sn or Mg or Sr or Ag; (3) choose pure lead or pb-ag alloy, utilize smelting furnace to melt pure lead or pb-ag alloy; (4) wrap up aluminium sheet around pure lead or pb-ag alloy being cast in equably aluminium sheet 1, the exposed 10-200mm in aluminium sheet upper end forms integument 2, the thickness 3-25mm of every pure lead of aluminium sheet or pb-ag alloy, the both sides of aluminium sheet and bottom are pure lead or pb-ag alloy, and its width is 3-25mm; (5) above-mentioned sheet material is rolled, making the thickness of every pure lead of aluminium sheet or pb-ag alloy is 1.0-5.0mm; (6) copper conducting beam 3 is connected and fixed on aluminium sheet, forms lead-aluminum composite anode plate.
Wherein: the composition of described aluminium sheet is fine aluminium or 1xxx series alloys or 3xxx series alloys or 5xxx series alloys or 6xxx series alloys.Before carrying out acid etching, also can be to uniform distribution perforate 4 in the middle of the aluminium sheet.Described pb-ag alloy is for by weight: silver-colored 0.1-0.5%, all the other are plumbous.
Beneficial effect of the present invention is: aluminium and aluminium alloy have the intensity height, the specific conductivity height, and characteristics such as proportion is little, and price is low, processing characteristics is good have obtained using widely in many industries as structured material and electro-conductive material.Aluminium and plumbous physics and chemical property are completely contradicted, but have complementarity.The present invention combines aluminium, lead material material advantage separately, with aluminium and the lead composition matrix material that matches, can obtain the intensity height, the specific conductivity height, and light specific gravity economizes on electricity, and corrosion resistance to sulfuric acid is good, and structure set material and functional materials are in the type material of one.Lead-compound insoluble anode the plate of aluminium gradient power savings is (compare with traditional lead-calcium-silver anode plate, bath voltage reduces about 180-200mv) significantly, physical strength height (bending strength improves 1 to 2 times), (alleviating about 1/3 than traditional pole plate) in light weight.And its tooling cost and work-ing life are suitable with traditional pole plate.At energy-saving and cost-reducing urgent day by day metallurgy industry, the compound insoluble anode plate of lead-aluminium has great economy at zinc electrolysis and cupric electrolysis field energy-saving and cost-reducing and is worth and realistic meaning.
