Description
Technical field
The present invention relates to chemical attack and electrochemical corrosion protection technology fields, it particularly relates to a kind of water cyclic system
Unite protective agent and its preparation process.
Background technique
Metal material by surrounding medium effect and damage, referred to as metal erosion.The corrosion of metal is the most common corrosion
Form.When corrosion, chemistry or electrochemistry heterogeneous reaction have occurred on the interface of metal, metal is made to be transferred to oxidation (ion) shape
State.This can significantly reduce the mechanical properties such as the intensity, plasticity, toughness of metal material, destroy the geometry of metal component, increase
Abrasion between part deteriorates the physical properties such as electrical and optical, shorten the service life of equipment, or even cause fire, explosion etc.
Catastrophic failure.Corrosion of the metal in nature fresh water can be divided into electrochemical corrosion and chemical attack.
Wherein, the feature of metal electrochemical corrosion in fresh water are as follows:
Fresh water is with neutral in the majority, and corrosion of metal is usually the electrochemical corrosion based on oxygen depolarization in fresh water.Oxygen
Presence be metal erosion in fresh water basic reason.If there is no O in pure water2, steel does not corrode generally, but usual day
Enough oxygen is always dissolved in right water, and superficial water is often by oxygen saturation, so can cause to corrode.Except the very high magnesium of electronegativity exists
Occur outside gas-evolving electrodes in fresh water, most metals are similar with steel, general in fresh water all to occur to be controlled by the diffusion of oxygen
The oxygen depolaxization corrosion of system.
The feature of metal chemical attack in fresh water are as follows:
China's underground water vast in territory differs greatly, and the corrosive ion of different content is contained in the underground water of some areas.
Such as: sulfate, chloride, fluoride etc..In the corrosion characteristics that the effect by water temperature and surrounding medium occurs, such as: fluorination
Object, with the calcium in water, can generate calcirm-fluoride (hydrofluoric acid) when water temperature is raised to 40 degree or more under the action of hydrogen, can to metal and
Glass generates heavy corrosion.
The influence of water temperature:
Dual character is presented in influence of the water temperature to activated state metal corrosion rate in open system, and one side water temperature increases,
The conductivity of water body increases, and water body convection current and diffusion velocity increase, and the anode and cathode resonant speed of metal erosion will all be accelerated, thus
Accelerate the general speed of corrosion process；On the other hand, temperature increases, and oxygen content is reduced in water body, and corrosion rate can be made to reduce.
Therefore, corrosion of metal speed is up to maximum value at a certain temperature, and if iron is in the water for crying out 3%NaC1, water temperature is 80 DEG C
When corrosion rate it is maximum.The temperature of the Natural Waters such as general rivers lakes and marhshes is between 0-30 DEG C, in this temperature range, steel
Corrosion is accelerated with the raising of temperature (when corrosion rate is spread control room, 10 DEG C of water temperature rising, the corrosion rate of steel by water oxygen
It about increases 30%).
The influence of pH value:
For the metals such as aluminium, iron, steel, copper, different metal is in different pH ranges, the pass of corrosion rate and pH value
There is large change in system, and the surface of aluminium changes very little within the scope of pH value 4-6, as pH value < 9, is conducive to the shape of hydroxide film
At, therefore corrosion rate is reduced with the increase of alkalinity；As pH value < 13, film dissolved destruction, corrosion rate is with alkaline increasing
Add and increases；As pH value < 7, film also dissolves, and corrosion rate increased dramatically with the increase of acidity.
The influence of flow velocity:
In the flow velocity lower stage, when flow velocity increases, oxygen is spread to metal surface to be accelerated, and the corrosion rate of steel increases；
When flow velocity increases to a certain extent, the diffusion velocity of oxygen makes steel enter passive state, and corrosion rate sharply declines；And when flow velocity increases to
When bigger numerical value, water is broken the passivation protection layer of metal surface to the impact cutting of metal surface, and impingment corrosion occurs for metal, thus
Corrosion is accelerated again.
For the problems in the relevant technologies, currently no effective solution has been proposed.
