Abstract

The invention relates to a mesh comprising metal wires. The mesh is coated with a zinc-nickel coating layer. The zinc-nickel coating layer comprises between 0.01 and 0.1 wt% Ni and is lead free. The invention further relates to a wire coated with such a zinc-nickel coating layer.

Description

Zinc-Nickel coating layer
Invention field
The present invention relates to comprise the manufacture method of the net and this net of Zinc-Nickel coating layer.The invention still further relates to the wire rod that adopts the Zinc-Nickel coating layer plating.
Background of invention
It is generally known in the art that and adopt batch processing method to carry out zinc-plated to steel work in the zinc melt plating bath by goods are immersed in.Plating bath contains usually and is up to 1.5 weight % lead, with the surface tension of avoiding forming scum silica frost and reducing zinc.
But because the legislation cause, many countries ban use of lead.
Summary of the invention
An object of the present invention is to provide net and the method for using unleaded plating bath to make coated mesh is provided with no lead-coat.
Another object of the present invention provides the net of the Zinc-Nickel coating layer that comprises excellent anti-corrosion performance.
Another purpose of the present invention provides the wire rod with Zinc-Nickel coating layer.
A further object of the present invention provides the method for making coated mesh by continuous plating technic.
According to a first aspect of the invention, provide the net that adopts the Zinc-Nickel coating layer plating.This net comprises metal wire.
Zinc-Nickel coating layer contains 0.01-0.1 weight %Ni.More preferably Zinc-Nickel coating layer contains 0.035-0.065 weight %Ni.
This Zinc-Nickel coating layer is unleaded.So-called " unleaded " refers to coating not leaded (inevitably except the trace).
As mentioned above, the general lead that adds in the zinc plating bath is to avoid forming scum silica frost.According to the present invention, being surprisingly found out that can the plating Zinc-Nickel coating layer and need not to add plumbous.
The zinc-nickel plating bath that Zinc-Nickel coating layer preferably adopts continuous solution and coating method that Netcom is crossed in hot dip process (galvanising) technology carries out plating.
In a preferred embodiment, at metal wire and Zinc-Nickel coating layer at the interface, the metal of metal wire and the alloy layer of Zinc-Nickel coating layer have been formed.This alloy layer thickness is 0.1-10 μ m, for example 8 μ m.
Compare with the net that adopts the zinc coating plating, adopt the erosion resistance that improvement is arranged according to the netting gear of Zinc-Nickel coating layer plating of the present invention.
Net can comprise welded mesh, for example comprises many nets at point of crossing place's electric welding wire rod together.Net can also comprise a kind of braiding structure that comprises metal wire.
The sieve aperture of net can be rectangle, square, sexangle or rhombohedral perforate.Net can perhaps can carry out bending or distortion for plane.
Wire rod is steel wire rod or adopt zinc or the steel wire rod of zn alloy coating plating preferably.
Wire cross-section can be circular, ellipse, rectangle or other Any shape.
In a preferred embodiment, wire cross-section is circular, and diameter is 0.1-5mm, as 0.4-1mm.
In a preferred embodiment, net preferably adopted zinc or zn alloy coating plating before adopting the Zinc-Nickel coating layer plating.
The wire rod of net can adopt zinc or zn alloy coating plating before being shaped to net.
Perhaps, the net that comprises metal wire adopts zinc or zn alloy coating plating.
According to a second aspect of the invention, provide the wire rod that adopts nickel zinc coating plating.This wire rod preferably includes steel wire rod.More preferably this wire rod comprises the steel wire rod with zinc or zn alloy coating plating.
According to a further aspect of the invention, provide the method for making coated mesh.
This method comprises the steps:
-net is provided;
-by hot dip process at described online plating Zinc-Nickel coating layer, described Zinc-Nickel coating layer contains 0.01-0.1 weight %Ni, described Zinc-Nickel coating layer is unleaded.
Described method can also comprise the steps: before the described Zinc-Nickel coating layer of plating, at described online plating zinc coating.
Described Zinc-Nickel coating layer adopts continuous solution and coating method plating.
The preferred embodiment of the invention is described
A preferred embodiment comprises a kind of welded mesh with steel wire rod.
Zinc-Nickel coating layer adopts continuous hot-dipping technology plating.The hot dip process plating bath contains 0.048-0.053 weight %Ni.
The dipping time of welded mesh in the hot dipping plating bath is 10 seconds to 5 minutes.
Be plated on online Zinc-Nickel coating layer and contain 0.035-0.065 weight %Ni, and unleaded.
At metal wire and Zinc-Nickel coating layer at the interface, formed the alloy layer of steel and Zinc-Nickel coating layer.Alloy layer thickness is 0.1-10 μ tm.
In order to estimate erosion resistance, the net that adopts the Zinc-Nickel coating layer plating is carried out salt-fog test.Table 1 has been listed the time span when 5% surface covers for Vandyke brown rust (DBR).Shown in the 2nd row is the erosion resistance that adopts the net of Zinc-Nickel coating layer plating; Shown in the 3rd row is the erosion resistance that adopts the net of zinc coating plating.
