The present invention proposes a kind of cleaning metal surface scale remover, according to the number of parts by weight, composed of the following components：20~30 parts of acrylic acid, 10~15 parts of hydroxyacetic acid, 4~10 parts of tertiary sodium phosphate, 3~6 parts of sodium metasilicate, 5~10 parts of calgon, 1~3 part of fatty acid polyethylene ether sodium sulfate, 80~90 parts of 1~2 part of laruyl alcohol polyoxy ether, 1~5 part of corrosion inhibiter and deionized water.The scale remover cleaning temperature is low, can quickly remove the dirt of metal surface, and metal is almost corrosion-free.
Description
Technical field
The invention belongs to field of metal surface treatment technology, and in particular to a kind of cleaning metal surface scale remover is suitable for
The surface clean for the large-sized boiler or heat exchanger that the various materials such as carbon steel, stainless steel, steel alloy, copper and copper alloy are constituted.
Background technology
For water equipment, fouling is an eternal topic, can be because of calcium ions and magnesium ions in water in boiler normal use
In the presence of, there is scale formation, by strong influence heat transfer efficiency, exist simultaneously great security risk, cause equipment operation not
Stablize.Scale remover is that one kind goes scale removal, the chemicals of a variety of dirty stains such as dirt generally to be compounded by various ingredients.Work
Industry is mainly used for removing heat transmission equipment, the dirt in boiler etc. with scale remover, and household descaling agent is mainly used for removing in water dispenser
Dirt.
The chemical cleaning medicament of metal surface mainly has two kinds of inorganic acid and organic acid, there are commonly hydrochloric acid, citric acid,
EDTA, hydroxyacetic acid, formic acid etc..These medicaments all have some disadvantages in current use, as hydrochloric acid cannot be used for Austria
Although family name's body steel and stainless steel, citric acid and EDTA have wide range of applications, but temperature in use it is higher (90-95 DEG C of citric acid,
EDTA120-140 DEG C), this creates the terminal the disadvantages that length of high and heating-up time is required heat source in implementation process, especially exist
Winter for the new-built unit of operation, heats up and is the largest restraining factors.And the processing of both organic acid waste liquids is more difficult, generally
It is transported to coal yard or grey field or by the way of biochemical treatment, the chemical treatment method of room temperature routine can not realize row up to standard
It puts.Therefore one kind has wide range of applications, cleaning temperature is low, it is short to implement the time for exploitation, and the lower pickling medicament of production cost
It is very necessary.

Further, according to the number of parts by weight, composed of the following components：
22~28 parts of acrylic acid, 12~14 parts of hydroxyacetic acid, 5~10 parts of tertiary sodium phosphate, 3~5 parts of sodium metasilicate, six inclined phosphorus
6~8 parts of sour sodium, 1~3 part of fatty acid polyethylene ether sodium sulfate, 1~2 part of laruyl alcohol polyoxy ether, 2~4 parts of corrosion inhibiter, and
85~90 parts of deionized water.
Further, corrosion inhibiter is methenamine, neopelex or aniline.
The preparation method of cleaning metal surface scale remover of the present invention is：
By acrylic acid, hydroxyacetic acid, tertiary sodium phosphate, sodium metasilicate, calgon, fatty acid polyethylene ether sodium sulfate,
Laruyl alcohol polyoxy ether after mixing, adds water and is mixed, then carry out 3~5min of ultrasound again with corrosion inhibiter,
.
Beneficial effects of the present invention：
1, the present invention using acrylic acid and hydroxyacetic acid as acidic leach agent, can very well by the dirt of metal surface into
Row dissolving can effectively improve dirt using fatty acid polyethylene ether sodium sulfate and laruyl alcohol polyoxy ether as surfactant
The dissolution rate of stain, tertiary sodium phosphate, sodium metasilicate and calgon further promote gold in dirt as metal ion chelation agent
Belong to ion remaval.
2, the present invention is free of the chlorion ingredient sensitive to stainless steel and steel alloy, can be used for carbon steel, stainless steel and alloy
The chemical cleaning of the various metal surfaces such as steel.The scale remover of the present invention just 3~5min of ultrasonication after mixing, has
It cooperates conducive to the chemical group between each component, improves scale removal efficiency.
