Description
Technical field
The present invention relates to a kind of oil-removing rust-removing agents and the preparation method and application thereof, belong to chemicals technical field.
Background technology
It is a kind of chemical reaction to get rusty, and will be got rusty when the time that iron is put has been grown.Iron gets rusty easily, in addition to the change due to it
Other than property is active, while also there are much relations with external condition.Moisture is one of the substance for making iron get rusty easily.However,
Only water will not make iron get rusty, and only when the oxygen in air is dissolved in water, oxygen reacts in the environment for having water with iron,
The thing of iron oxide can be just generated, here it is iron rust.Iron rust is a kind of substance of brownish red, it is so hard unlike iron, holds very much
Easy to fall off, after one block of iron gets rusty completely, volume can swell 8 times.If iron rust does not remove, this spongiform iron rust is particularly easy to inhale
Moisture is received, iron also just gets rusty faster.Iron is in the Shi Huigeng weights that get rusty, 3 to 5 times about original of weight.
Traditional chemical derusting can be chemically reacted usually using strong acid, acid with iron rust and metal oxide, and generation can
Dissolubility salt, to achieve the purpose that derusting, while derusting, acid again can and underlying metal react and release hydrogen, Hydrogen Energy pair
The oxide skin of iron rust and indissoluble generates pressure, is conducive to the reduction of their peeling and high price iron, accelerates the process of pickling, but pass
There is also apparent defects for the acid solution processing method of system：The generation of a large amount of hydrogen can make steel generate hydrogen embrittlement i.e. in processing procedure
Phenomenon causes the mechanical properties decrease of metal, influences the intensity of steel itself；Acid mist is easily formed simultaneously, influences operating personnel's
Equipment around health and corrosion and environment；The consumption of acid solution is also larger, increases processing cost；This kind of acid can be formed steel
Excessive erosion.In addition the residue largely generated need to be discharged often, not only heavy corrosion industrial pipeline, but also contaminated soil and environment.This
Outside, strong acid is not easy to transport, and there are certain danger.
In order to solve the above problems, it is badly in need of a kind of not having to strong acid, efficient, easy to operate, convenient transportation removing
Oily rust remover.
