Description
Technical field
The present invention relates to field of metal surface treatment technology, more particularly to one kind for metal material and metal product
The environment-friendly type descaling and derusting anticorrosion liquid that is handled of surface.
Background technique
The descaling and derusting anticorrosion of metal surface is concerned as technical problem always.Water makees the heat exchange dress of cooling medium
Set, in use for some time in system will fouling, and be formed on container or duct wall, as all kinds of heat exchangers pipe in
On wall.The main component of scale is calcium carbonate and magnesium carbonate.Meanwhile metal surface easily generates oxide, that is, metal corruption
Erosion and rust stain.The scale and rust stain of deposition influence heat exchanger effectiveness.For example, fouling will to exchange heat when reaching 0.5mm thickness
Device cooling system cannot normally transmit temperature.When scale is more than 0.8mm thickness or more, it is unsmooth to will lead to waterway circulating, shadow
It rings equipment to work normally, reduces heat transfer efficiency, equipment can be damaged when serious.The method that tradition removes scale is to use strong acid or strong
Alkali cleaning, although this cleaning method can remove scale, the etching of body metal is serious, and pollutes environment.
It is existing more for the cleaning agent kind veriety of equipment scale on the market, mostly using acidic materials and corrosion inhibiter etc.
To dissolve dispersion calcium and magnesium salt scale.But these cleaning agents mostly cleaning effect is bad, after some equipment metal cleanings when shorter
It is interior to get rusty again again；And corrosivity is big, safety is poor, and storing is also inconvenient.These problems are not solved preferably always
Certainly.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of carbene environment-friendly type descaling and derusting anticorrosion antirust liquid and its preparations
Methods and applications.
The present invention is realized by following technical proposal:
A kind of carbene environment-friendly type descaling and derusting anticorrosion antirust liquid and preparation method thereof, it is characterised in that: its component and its matter
Measure percentage are as follows: carbene 1~10%, promotor 0.1~1.0%, dispersing agent, 0.01~1.00%, surplus is deionized water.
Wherein, the carbene is water-soluble carbene sol body, has very strong elecrtonegativity, quickly dissolves dirty stain and net catches calcium
The metal ions function such as magnesium, meanwhile, and be the reductant-oxidant of metal oxide.Have a scale removal rust and antiscale is become rusty special work
With.Its pH value is 0.5~3, electromotive force E is 280~380mv, and granularity ф is 0.3~20nm, and size distribution ψ is D90~D98,
Solutes content is 0.1%~1%.Preferably, pH value be 1.5~2.5, electromotive force E be 300~320mv, granularity ф be 0.3~
5nm, size distribution ψ are D95~D98, and solutes content is 0.3%~0.6%.
Raw material are taken from normal carbon (setting carbon or amorphous carbon) and deionization pure water, unbalanced using carbon molecules
Electronics distribution, be electrochemically reacted in the environment of pure water, the single carbon molecule of generation and more carbon molecules are anti-in redox
Novel substance is obtained in answering, and forms the liquid of carbon sol state.Single carbon and more carbon molecules in carbon sol liquid form not of uniform size
Carbene structural body.Prepared using acoustochemical intervention is carried out while electrochemistry, with three wave bands ultrasound (20KHz, 45KHz,
Environmental parameter 80KHz) makes constantly to produce countless microcosmic (nanoscale hole) subenvironments in solution, this subenvironment is in wink
Between (<0.001S) generate high temperature, (>=5000 DEG C of high pressure；>=100Mpa) energy unit, form the violent expansion in liquid hole
Compress the conversion of cycle alternation energy.H in carbene structural body and water+Ion, OH-Ion in such circumstances, can carry out various knots
Structure and form oxidation reaction obtain above-mentioned high activity carbene.
Wherein, the promotor is fumaric acid, has the function of acidity regulator, anti-oxidant auxiliary agent, promotor etc., has
Strong buffer function can keep solution in pH stability and the etch-proof important function of long-acting descaling and derusting.
Wherein, the dispersing agent is low carbon mixed alcohol, specially C1~C4 alcohol-based mixtures.Rudimentary alcohols is water-soluble
Good, energy and water are miscible with arbitrary proportion.Since carbon is different with the electronegativity of oxygen, so carbon-oxygen bond is polar bond, alcohol is a pole
Property molecule.When hydroxyl and double or triple bonds carbon phase connect, the sp3 hybridized orbit of oxygen then forms σ key with the sp hybridized orbit of carbon.?
Cooperate in water-soluble carbene sol body and plays the role of superpower dispersibility.It more specifically can be by C1 alcohol 1%~10%, C2 alcohol 50%
~90%, C3 alcohol 5%~30%, C4 alcohol 1%~10% form.Preferentially are as follows: C1 alcohol 2%, C2 alcohol 86%, C3 alcohol 8%, C4 alcohol
4%.
