Description
Technical field
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.
Background technology
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 and removes plastic substrate, reduction, thermal treatment → foamed metal strip.Topic between yet technology in the past exists necessarily, these technology can reduce two kinds of representative modes: the processed conduction bubble foam plastics base band negative electrode of the first passes through coating bath, plating bath in a horizontal manner, its shortcoming is: (1) conduction bubble foam plastic tape negative electrode is extremely soft, very easily distortion, for keeping its level must apply bigger longitudinal stretching tension force, cause this band longitudinal extension distortion in preceding several pre-plating tanks, and the plated film of weakness pulled out crackle, influence quality; (2) production line continues very longly in the horizontal direction, the longest reach 80 surplus meter (see figure 1); Its two be processed conduction bubble foam plastic tape negative electrode in coating bath, plating bath up and down bending pass through, like a plurality of successive English alphabets " W ", although this kind method is adopting larger-diameter roller in the back plating district, unavoidably will be thicker and hard crisp composite foamed body coating is bent and separated out tiny crack; Though compact construction, travelling speed lower (12.7cm/min), production efficiency is hanged down (see figure 2).All adopt soluble anode in these technology in addition, also have some problems: need add the anode enclosure, need often filling to replenish anode metal piece and maintenance anode, and 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, make quality of coating generation defective, influenced production efficiency and quality product.
Summary of the invention
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; Exempt sequence of operations and disadvantageous effect simultaneously about soluble anode.
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 → conductionization processing → electrodeposit metals coating forms composite foamed body → pyrolysis and removes plastic substrate, reduction, thermal treatment → foamed metal strip, it is characterized in that electrodeposit metals coating forms composite foamed body technology section (referring to Fig. 3) on conduction bubble foam plastic tape negative electrode:
(1) plating process is:
--forebody is each plating district of pre-coating bath, and being plated conduction bubble foam plastic strap is negative electrode, passes through coating bath in " W " mode of bending up and down; The conduction bubble foam plastic tape of the pre-coating bath first plating district negative electrode is attached on the conduction titanium belt surface and immerses plating bath with the titanium band; All the other negative electrode conductive rollers are more than the tank liquor face;
--latter half of each plates the district for the thickening coating bath, and anode is opposed up and down by plating negative electrode band, and quilt plating band level is passed through coating bath.
(2) all anodes adopt insoluble anode, and tank liquor circulates, and guarantee Ni
2+Concentration is in normal range;
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 being Watt liquid, nickelous chloride type, two salt type, nickel sulfamic acid tank liquor etc., the pre-coating bath first plating district negative electrode can by conduction bubble foam plastic tape be attached on the conduction titanium belt surface immerse plating bath and make strap electroplating with the titanium band after, enter another electrolyzer after this conduction titanium band is produced by pre-coating bath and carry out electrolysis as anode, the metal that is plating on it is removed in dissolving.The present invention because:
(1) forebody in the electrolysis process section is each plating district of pre-coating bath, by plating conduction bubble foam plastic strap is negative electrode, distinguish by each plating in " W " mode, because coating is thinner, soft by plating negative electrode band, easily bending and the coating crackle can not occur is to reduce the integral device floor space, makes compact construction and adopts " W " mode of bending up and down; This is partly except that the conduction titanium band of the pre-coating bath first plating district negative electrode; Other negative electrode conductive rollers is on the tank liquor face.This part length only is below 1/3rd of horizontal preplating part.
(2) distinguish for the thickening coating bath respectively plates the latter half of of electrolysis process section, plated negative electrode band opposed netted insoluble anode up and down owing to adopt, 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.
(3) the conduction bubble foam plastic tape of the pre-coating bath first plating district negative electrode is attached on the conduction titanium belt surface and immerses plating bath with the titanium band, eliminated and be exposed on the plating bath face, the resistance and the volts lost of that section conductive segment band to be plated, 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.
(4) the conduction titanium band of the pre-coating bath first plating district negative electrode is walked around guide roller, after the titanium band is produced by pre-coating bath, just enter another electrolyzer and carry out electrolysis as anode, deposit to metal on the titanium belt surface to remove through the porous plastics mesh, guarantee that the titanium belt surface is bright and clean, can not damage the porous plastics base band, avoid influencing quality of coating.
(5) 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 its 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.
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.
