Abstract
The invention provides an efficient corrosion inhibitor for nickel alloy. The efficient corrosion inhibitor for the nickel alloy comprises solute and a solvent, wherein the solvent is water, and the solute comprises sodium persulfate with the concentration being 1-2 mg/L, imidazoline amide with the concentration being 25-30 mg/L, polyaspartic acid with the concentration being 3-5 mg/L, itaconic acid with the concentration being 2-3 mg/L and mercapto-benzothiazole sodium with the concentration being 1-3 mg/L. The efficient corrosion inhibitor for the nickel alloy is prepared according to the corrosion-protection technological requirement of nickel alloy materials and has the special effects of dirt removal, rust removal, and clad layer defect removal on the surfaces of the nickel alloy materials, a firm and compact single-molecule protective film is formed on the surface of the treated nickel alloy, and thus a corrosion inhibition effect is achieved.
Description
Technical field
The present invention relates to anticorrosion technique field, specifically a kind of efficient nickel alloy corrosion inhibiter.
Background technology
In American Society Testing and Materials《Standard definition with regard to corrosion and corrosion test term》In, corrosion inhibiter is " one
When kind is present in environment (medium) with suitable concentration and form, can prevent or slow down chemical substance or severalization of corrosion
Learn the mixture of material." in general, corrosion inhibiter refers to that those are used in the material that protective action is played in metal surface, adds micro
Or this kind of chemical substance can make metal material corrosion rate in the medium substantially decrease up to be zero on a small quantity.Can also protect simultaneously
Hold the original Physical and mechanical properties of metal material constant.Reasonable employment corrosion inhibiter is to prevent metal and its alloy in surrounding medium
The middle effective ways that corrosion occurs.Inhibiter technology is due to having good effect and higher economic benefit, it has also become anti-corrosion
One of most widely used method in erosion technology.Especially in the production and processing of oil product, Chemical cleaning, atmospheric environment, industry
With, in water, machine, instrument manufacture and petrochemical production process, neutralization technology has become one of main anticorrosion means.
The English major name of corrosion inhibiter：anti-corrosive.corrosion inhibitor.It is referred to as corruption
Corrosion inhibitor.Its consumption very little (0.1%～1%), but effect is significant.(boiler feed water, circulation are cold to be mainly used in neutral medium
But water), acid medium (hydrochloric acid descaling, the acid dip solution of plating piece rust cleaning before plating) and gas medium (vapor phase corrosion inhibitor
Agent).Inhibition efficiency is bigger, and the effect of suppression corrosion is better.Sometimes several inhomogeneity corrosion inhibiter of relatively low-dose use cooperatively can
Obtain preferable corrosion mitigating effect, this effect is referred to as cooperative effect；If on the contrary, when dissimilar corrosion inhibiter is used in conjunction with the contrary
Reduce respective inhibition efficiency, then referred to as antagonistic effect.The corrosion mitigating effect of corrosion inhibiter and the pH of its concentration and medium
Value, temperature, flow velocity etc. are closely related, therefore strictly should be selected according to protected object, environmental condition.
