Description
[technical field]
The present invention relates to environmental protection Zn-Fe alloying plate technique field, specifically, be a kind of zinc electroplating bath ferroalloy
Change the manufacture method of plate.
[background technology]
Zn-Fe alloying plate is conventionally used to automobile production, has phosphatization good, crystallizes finer and closely woven than pure galvanized sheet,
The characteristics such as weldability is good, resistance to water, good corrosion resistance, and coating is good, but its defect such as alloy-layer
Being easier to efflorescence, form graininess, surface-active is high, oxidizable etc. also limit its at other field should
With.
The methods such as the Cr VI passivation of tradition Zn-Fe alloying plate use or oiling ensure antiseptic property, one
Aspect Cr VI is passivated not environmentally, and antiseptic property is the best, and striated surface easily occurs, affects follow-up
Use.Oiling is only used for automobile industry, can not reach completely as building door slab industry decay resistance
To requiring, and oiling can produce impact to follow-up cleaning and paint performance.Many unfavorable factors limit
Alloying plate is in the application of building door board industry.
Door-plate industry early stage mainly use cold-reduced sheet as base material, for Improving The Quality of Products, in the industry
The use of middle galvanized sheet is the most extensively got up.Use alloying sheet material can make full use of conjunction as base material
Every advantage of aurification sheet material, Improving The Quality of Products.But due to traditional alloying sheet material post processing side
The restriction of formula so that have bigger problem in actual application, limits the expansion application of alloying sheet material.
[summary of the invention]
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of environmental protection Zn-Fe alloying plate
Manufacture method.
It is an object of the invention to be achieved through the following technical solutions:
The manufacture method of a kind of environmental protection Zn-Fe alloying plate, it concretely comprises the following steps: depended on by Zn-Fe alloying plate
