Description
Technical field
The invention belongs to the Field of Heat-treatment of nickel foam, and in particular to a kind of tape splicing method of nickel foam.
Background technology
Continuous band-shaped foam method for preparing nickel includes conducting, plating, sintering, finished product four master operations of cutting, wherein
Sintering circuit produces one of critical process for nickel foam, and sintering process control directly affects nickel foam quality.In continuous band-shaped bubble
It must cause general tape splicing material all by 800~1000 DEG C of high-temperature oxydations and reduction treatment in foam nickel sintering circuit production process
Can not it is harsh herein in the case of use；So sintering circuit in process of production need be between human assistance be rolled up after heat treatment
It connects ability performance and realizes continuous production.
Existing volume indirect belt mode is taken after sintering is heat-treated, using auxiliary coarse ribbon (e.g., the cotton of soft surface
Cloth, sponge) be bonded in volume two between realize product connection, this operation takes manually more people assist to complete.
Since sintering heat treatment process needs 800~1000 DEG C of high-temperature process, and it is currently used for connecting between cheap ribbon
Soft material can not all resist oxidation and reduction reaction at these elevated temperatures；And the soft material price that can resist such high temperature is held high
It is expensive.
Using during switching tape splicing operating process between the volume of sintering production several operating personnel is needed to assist ability complete now
Into, and specific purpose tool need be prepared and waited in advance；Since product is just in continuous operation during tape splicing, when being operated to operating personnel
Between all there are certain requirements with proficiency.Because existing operation restrictive condition is more, as gone wrong in a certain respect all in operating process
Product direct losses or continuous flow procedure may be caused to interrupt.
The content of the invention
The technical problem to be solved in the present invention is to provide the tape splicing methods of a kind of good economy performance, time saving and energy saving nickel foam.
Present disclosure includes the following steps：
The marginal portion of nickel foam after unreeling is overlapped, is connected by crimp together, is then heat-treated, finally
Winding；The pressure of the crimping is >=15KgN, and crimping width is 15~25mm.
The aperture of the nickel foam product is 80-130PPI, surface density 150-1000g/m2, 1.0~2.5mm of thickness, hole
Gap rate >=90%.
The view picture thickness of the lap is less than the sum of nickel foam product thicknesses of volume two.
The local thickness of the lap is less than the sum of nickel foam product thicknesses of volume two.
The local shape is circular, square and diamond shape one or more.
Beneficial effects of the present invention are：
1. the tape splicing flow of the present invention is heat-treated first to carry out tape splicing, band is followed by with traditional heat treatment afterwards
Flow is compared, and the present invention carries out tape splicing when unreeling and replacing and switch between product is rolled up, and is avoided another extremely heat treatment fire door and is waited
Tape splicing eliminates the stand-by period of operation, improves work efficiency.
2. the tape splicing mode of the present invention, without aiding in attachment between volume, reduce time and preparation and
Daily auxiliary tool management work reduces workload, and then substantially reduces cost.
