Abstract
A method of extruding and manufacturing a sacrificial zinc anode tape, comprises the following steps: 1) heating an extruding cylinder and a mould, the heating temperatures of the extruding cylinder and the mould are 200degree C-300degree C, and 240degree C-400 degree C, respectively;2) heating zinc or zinc alloy as the raw material, the heating temperature is 120degree C-300degree C; 3) inserting an iron core through the heated mould; 4) putting zinc or zinc alloy as the raw material into the extruding cylinder, starting the extruding machine, by extruding, a sacrificial zinc anode tape is formed from semi-product. a sacrificial zinc anode tape by extrusion could have a limitless length. Iron core in the zinc tape couldn't be deformed and extended, and keeps good contact with the base zinc or zinc alloy. Iron core has a small degree of eccentricity which ensures the sacrificial zinc anode tape eroded uniformly. The invention is applicable for cathode protection of boats, mechanical devices in sea and saline water, and pipelines and cables in soil with low electrical resistivity.
Description
Technical field
The present invention relates to a kind of extruding method for making of sacrificial zinc anode belt.
Background technology
The direct and consequential damage that corrosion causes to metallic substance is huge.To each concrete corrosion system, the anti-corrosion measure of employing should be taken all factors into consideration according to physical condition, and wherein galvanic protection is a kind of important method of corrosion control.Zinc that uses in the cathode protection technology and zinc alloy anode, it is good to have a solubility property, the current efficiency height; protect effective, easy to manufacture, lower-price characteristic; be the ideal sacrificial anode material, be widely used in the structures protections such as seawater, fresh water and subterranean pipeline.The cross-sectional shape of zinc anode belt and the iron core at center and be one of critical process of producing.Normally used zinc anode belt adopts foundry engieering production mostly, and anode strap and protected 's contact area is little, has shortcomings such as low temperature brittleness under the lower environment of temperature.
Summary of the invention
The extruding method for making that the purpose of this invention is to provide a kind of quality that improves product and easily processing, a kind of sacrificial zinc anode belt that production efficiency is high
For achieving the above object, the present invention takes following technical scheme: a kind of extruding method for making of sacrificial zinc anode belt comprises the steps:
(1) container and mould are heated, the Heating temperature of container is 200 ℃-300 ℃, and the Heating temperature of mould is 240 ℃-400 ℃;
(2) simultaneously raw material zinc or zinc alloy are heated, Heating temperature is 120 ℃-300 ℃;
(3) in heated mould, penetrate iron core;
(4) raw material zinc after will heating or the zinc alloy container of packing into starts extrusion machine, by extruding, makes blank promptly become sacrificial zinc anode belt through mould.
Inventive point of the present invention is that the manufacture method of sacrificial zinc anode belt is to be improved to extruding method for making by castmethod, and the used extrusion machine of extruding method for making is known equipment.The numerical value of the Heating temperature of the Heating temperature of raw material, the Heating temperature of container, mould etc. is decided according to different raw material particular cases, and raw material is zinc or zinc alloy.
Advantage of the present invention is:
(1) extruding sacrificial zinc anode belt maximum length can reach endless, can require decision length according to reality, makes things convenient for engineering construction.
(2) the iron core degree of eccentricity at extruding sacrificial zinc anode belt center is little, indeformable, is not stretched.Contact good between iron core and the matrix zinc.
(3) adopt extruding method for making, easily processing, production efficiency height.
(4) extruding sacrificial zinc anode belt smooth surface, zero defect.
(5) the extruding sacrificial zinc anode belt has lower ductile-brittle transition temperature, so can use under lower temperature environment.

Embodiment
Embodiment 1
Mould is heated, and Heating temperature is 300 ℃; With the iron core rust cleaning, in heated die, penetrate iron core, mould dress mould.Be 190 ℃ raw material TypeII (II type) the zinc container of packing into then with Heating temperature, the Heating temperature of container is 210 ℃; Start tonnage and be 650 tons extrusion machine, make raw material pass through mould, promptly make extruding A type sacrificial zinc anode belt.
Embodiment 2
Mould is heated, and Heating temperature is 380 ℃; With the iron core rust cleaning, in heated die, penetrate iron core, mould dress mould.Be 240 ℃ raw material TypeII (II type) the zinc container of packing into then with Heating temperature, the Heating temperature of container is 240 ℃; Start tonnage and be 650 tons extrusion machine, make raw material pass through mould, promptly make extruding D type sacrificial zinc anode belt.
Made extruding sacrificial zinc anode belt as shown in Figure 1 and Figure 2, matrix zinc or zinc alloy 1 contact well with intermediary iron core 2, the interface is seamless.Iron core 2 degree of eccentricity are little, and are indeformable, are not stretched.
As shown in Figure 3, extruding sacrificial zinc anode belt maximum length of the present invention can reach endless, can require decision length according to reality, coils into the extruding sacrificial zinc anode belt 3 of web-like, makes things convenient for engineering construction.
In sum, extruding sacrificial zinc anode belt maximum length of the present invention can reach endless, can require decision length according to reality, the convenient use.The iron core at zinc band center is indeformable, is not stretched.Contact good between iron core and matrix zinc or the zinc alloy.The iron core degree of eccentricity at zinc band center is little, guarantees the zinc anode belt corrosion evenly.Ductile-brittle transition temperature is low, can be at normal construction under the low temperature environment.Extruding sacrificial zinc anode belt of the present invention is applicable to the galvanic protection of facility anticorrosive metals such as pipeline in boats and ships, mechanical means and the low-resistivity soil in seawater, the brine media, cable.
