Abstract
A process for continuously preparing coiled foamed metal band features that the electrically deposited metal layer is used to form composite foam (1) all anodes are insoluble ones, and the bath liquid flows cyclically to ensure Ni+The concentration is in the normal range, (2) the plating process is that the first cathode of preplating is dissolved in the plating solution, (2) the plating areas of the first half part are preplated, the band material to be plated passes through the plating tank in a way of bending W up and down, the cathode is on the liquid level of the tank, (2) the second half part is preplatedThe anode is arranged opposite to the upper and lower parts of the strip material to be plated, and the strip material to be plated horizontally passes through the plating tank. The technology has the advantages of improving the production efficiency, ensuring the product quality, having compact structure and small occupied area, and simultaneously saving a series of operation problems related to the anode.
Description
The present invention relates to the manufacturing technology of functional materials, providing a kind of especially is the technology of the producing rolled foamed metal strip continuously of base band with the flex foam.
In the manufacturing technology of foaming metal functional materials, be that the patented technology of core process is used in the majority because of it is economical and practical than other technology with the electro-deposition techniques.The main technique flow process is: porous plastics base band Chemical Pretreatment--conductionization processing--electrodeposit metals coating forms composite foamed body--pyrolysis removes plastic substrate, reduction, thermal treatment--foamed metal strip.Yet there is certain problem in technology in the past, these technology can reduce two kinds of representative modes: the processed porous plastics base band of the first is passed through coating bath, plating bath in a horizontal manner, its shortcoming is that production line continues very longly in the horizontal direction, the longest reach 80 surplus meter (see figure 1); Its two be processed porous plastics band in coating bath, plating bath up and down bending pass through, like a plurality of successive English alphabets " W ", although this kind method larger-diameter deflector roll of employing in back plating district makes thicker composite foamed body coating bend out tiny crack unavoidably; Though compact construction, travelling speed lower (12.7cm/mm), production efficiency is hanged down (see figure 2).All adopt soluble anode in these technology in addition, also have some problems: add the anode enclosure, filling replenishes anode block metal block and maintenance anode, all must shut-down operation, also have a series of problems that the anode sludge brings etc.These problems one are to make to produce to pause, and increase labor service and cost; The 2nd, coating matter is retransmitted given birth to defective, influenced production efficiency and quality product.
The object of the present invention is to provide a kind of technology of producing rolled foamed metal strip continuously, to address the above problem.This technology has concurrently enhances productivity, and guarantees quality product, and compact construction takes up an area of few; Save problem simultaneously about the anodic sequence of operations.
The invention provides a kind of producing rolled foamed metal strip continuously technology, the main technique flow process is: porous plastics base band Chemical Pretreatment--the conductionization processing--and electrodeposit metals coating forms composite foamed body--pyrolysis removes plastic substrate, reduction, thermal treatment--, and foamed metal strip is characterized in that forming composite foamed body technology section at electrodeposit metals coating:
(1) all anodes adopt insoluble anode, and tank liquor circulates, and guarantee Ni
+Concentration is in normal range;
(2) plating process is:
--preplating first negative electrode dissolves in plating bath;
--forebody preplating is the plating district respectively, is plated band and passes through coating bath in " W " mode of bending up and down, and negative electrode is on the tank liquor face;
--each plating district of latter half of thickening plating, anode is opposed up and down at quilt plating band, and is passed through coating bath by plating band level.
Insoluble anode is a DSA quasi-metal oxides electrode, as titanium plating ruthenium yttrium electrode, titanium lead oxide-coated electrode.And nickel plating bath is general, just need circulate, and guarantees Ni
2+Concentration is in normal range, as can being Watt liquid, and nickelous chloride type, two salt type, nickel sulfamic acid root liquid etc., first negative electrode can import plating bath by the titanium band, enters another electrolyzer after being produced by pre-coating bath and carries out electrolysis as anode.The present invention because:
(1) in the electrolysis process section, all anodes adopt insoluble anode, such anode has not only been exempted the numerous and diverse operation and the anode sludge problem thereof of soluble anode, because anode allows current density big, passivation does not take place, the efficient height also, and insoluble anode can be done much smaller than the volume of soluble anode, thereby favourable enhancing productivity makes compact construction, guarantees quality of coating.
(2) in each plating district of the forebody preplating of electrolysis process section, because coating is thinner, it is soft plate band, and easily bending and the coating crackle can not occur is to reduce the integral device floor space, makes compact construction and adopts " W " mode that bends up and down; This partly except that first negative electrode other negative electrode on the tank liquor face.This part length only is level or below 1/3rd of this preplating part.
(3) distinguish in latter half of each plating of thickening plating of electrolysis process section, owing to adopt opposed insoluble anode up and down, be beneficial to the tank liquor circulation and pass anode arrival by the plating band, favourable raising allows current density and production efficiency, this part device height and length are reduced, for horizontal mode in the past partly height and length 1/2nd.
(4) preplating first negative electrode immerses plating bath, eliminated and be exposed on the plating bath face, the resistance and the volts lost of section invalid conductive segment band of that between from the anode to the negative electrode, and just be that this section is very big because of the conductionization membrane resistance, limited the plating current density, allow much bigger current density plating far away, favourable enhancing productivity with the technology of the present invention.
(5) first negative electrodes adopt the titanium band to walk around the rotating roller mode, after the titanium band is produced by pre-coating bath, just entering another electrolyzer carries out electrolysis as anode and deposits to kish on the titanium band cathode surface to remove through the porous plastics mesh, the assurance cathode surface is bright and clean, can not damage the porous plastics base band, avoid influencing quality of coating.
In a word, implement producing rolled foamed metal strip continuously with the technology of the present invention, the production efficiency height, travelling speed can reach per minute more than 1 meter, and quality of coating is reliable.By embodiment in detail the present invention is described in detail below in conjunction with accompanying drawing.
