Problems solved by technology
[0003] 1) The elasticity of metal copper is not enough, and the formed composite cylinder is very easy to deform;
[0004] 2) Due to the existence of copper, it is difficult to recycle waste nets;
[0005] 3) The price of copper is also relatively high, and the upward trend is obvious

Embodiment Construction
[0022] see figure 1 , the printing and dyeing of the present invention relates to a five-layer composite metal circular screen, with a nickel layer with a thickness of 20-30 μm as the core layer 1 of the rotary screen, depositing iron or iron-nickel alloy on both sides of the front and back of the core layer 1 as the core layer of the rotary screen The two intermediate layers 2 are deposited with a nickel layer on the surface of the two intermediate layers 2 to form two protective outer layers 3 of the cylinder net, forming a composite network structure. Its preparation method mainly comprises the following process steps:
[0023] 1) Plating core layer
[0024] After the passivation treatment, the mesh mold is used as the cathode and placed in the nickel plating tank. Under the condition of 50-70℃, the first nickel plating is carried out to make a pure nickel single mesh as the core layer;
[0025] 2) offline
[0026] Take out the mesh mold with single mesh from the nickel ...

Abstract
The invention relates to a five-layered composite metal rotary screen for printing and dyeing, and a preparation method thereof. The rotary screen comprises a nickel layer with a thickness of 20 to 30 mum as the core layer (1) of the screen, two intermediate layers (2) formed by depositing iron or iron-nickel alloy on the front or the back sides of the core layer, and two outer protection layers (3) formed by depositing a nickel layer on the surfaces of the two intermediate layers to form a composite screen structure. The manufacture method comprises the following steps: (1) passivating a screen mold to serve as a cathode, disposing in a nickel-plating tank, plating nickel for the first time to obtain a pure-nickel single screen as the core layer; (2) separating the screen; (3) disposing the core layer in an iron or iron-nickel alloy tank, plating iron or iron-nickel alloy to obtain the two intermediate layers, wherein the molar ratio of nickel to iron in the tank is controlled to (5 to 15):1 during plating iron-nickel alloy; and (4) disposing the core layer and the two intermediate layers connected as a whole by plating into a nickel plating tank, plating nickel for the second time to obtain the two outer protection layers. The usage of the composite metal rotary screen can greatly save the use amount of nickel and lower the cost, and the waste screen can be easily recovered and reused.
Description
technical field [0001] The invention relates to a rotary screen for printing and dyeing and a preparation method thereof, in particular to a rotary screen for fabric printing industry and a preparation method thereof. Background technique [0002] Since the invention of the electroplated nickel mesh by Peter Zimer in Austria in 1961 and the introduction of the gluing cylinder by the Stoke Company in the Netherlands in 1963, the improvement of the printed nickel mesh has mainly focused on the improvement of the mesh number and opening ratio, as well as the improvement of the hole shape. Optimized for unfolding. With the improvement of people's living standards, the consumption of calico continues to increase. The widespread use of printed nickel mesh must consume a large amount of nickel resources. As the price of metal nickel continues to rise, the cost of nickel mesh is gradually increasing. Chinese patent (CN1478652) discloses a nickel-copper composite cylinder and a pr...
