Description
Technical field
The present invention relates to concrete reinforcement inhibiter technical field, particularly a kind of composite concrete reinforcing bar inhibiter with excellent corrosion mitigating effect.
Background technology
In order to suppress corrosion of metal, all kinds of inhibiter is widely used in metal cleaner and metal scale remover.Inhibiter, by its composition, may be summarized to be three classes:
1. passivator: the strong oxidizer being generally mineral-type.Such as, chromic salt, nitrate, molybdate etc.Their effect is exactly make corrosive medium have stronger oxidisability, makes the oxide film that metallic surface keeps complete.Its effect and electrochemical anodic protection play the same tune on different musical instruments.
2. organic inhibitor: comprising restrainer and corrosion inhibiting grease.The pickling of iron and steel is the requisite pretreatment process of many courses of processing, and object is the oxide compound of removing steel surface, but this process must also can make metal itself be corroded.In order to reduce corrosion of metal, inhibiter must be added when pickling.This inhibiter has usually: the toluene thiocarbamide, dipropyl sulfide, diamyl amine, formaldehyde, contraposition thiocresol etc. of ortho position and contraposition.Its mechanism of action is: inhibiter is adsorbed in the surface of iron and steel at large, makes to cause the electrode reaction of corrosion to be subject to resistanceization during pickling iron and steel.Some inhibiter can improve the overvoltage of hydrogen, and the cathodic reaction of reducing hydrogen ions is obstructed; Some inhibiter can make Fe forms be that the reaction of ferrous ion is obstructed, and make anodic polarization.But it is generally acknowledged, inhibiter can slow down the reaction of negative electrode and anode, makes the erosion rate of iron and steel obviously reduce simultaneously.Corrosion inhibiting grease is used for temporarily anticorrosion at transport and duration of storage of metallic substance and product, and it adds a small amount of organic additive primarily of oil, fat or wax etc. and forms.This organic additive is generally polar compound, adsorbable in metallic surface.Its mechanism of action is similar in appearance to restrainer, and difference is, requires that the additive in corrosion inhibiting grease is had an effect under the condition of weakly acidic pH, and restrainer requires to have an effect in acid condition.Organic substance as the additive in corrosion inhibiting grease is generally: the salt etc. of organic amine, zinc naphthenate, the product of various petroleum oxidation, the alkali and alkaline earth metal ions of sulphonated oil.
3. vapour-phase inhibitor: vapour-phase inhibitor is a kind of can volatilization, but lower and its steam of vapour pressure has the material of preservative activity.It is mainly used in important machine parts (as bearing etc.) storage and transportation in anticorrosion.Its anticorrosion mechanism is not fully aware of, main or relevant in the absorption of metallic surface with vapour-phase inhibitor.The most also be use the widest a kind of vapour-phase inhibitor to be nitrous acid bicyclohexane base amine, this is a kind of nontoxic scentless white crystals, and volatilization is comparatively slow, in good sealed package space, and can effective anticorrosion phase one year to steel piece under room temperature.Its shortcoming is, can accelerate the corrosion of some non-ferrous metals as zinc, manganese, cadmium etc., so should be specifically noted that in use in product with or without non-ferrous metal.
Be derived from the various compositions of above-mentioned 3 kinds of inhibiter, carry out combining or arranging in pairs or groups, often have better effect.But inhibition ingredient is confined in mentioned kind, also constrain the development of inhibiter and the raising of corrosion mitigating effect.
