Abstract
The invention relates to a cleaning agent for a surface of chemical equipment. The cleaning agent is prepared through compounding the following ingredients in parts by mass: 10-20 parts of anhydrous sodium metasilicate, 10-25 parts of tetrachloroethylene, 10-25 parts of sucrose fatty acid ester, 10-30 parts of hydroxylethylidene diphosphate, 10-25 parts of imidazoline betaine, 3-5 parts of tetrachloro meta-phthalonitrile, 2-4 parts of methyl benzotriazole and 50-150 parts of deionized water. According to the cleaning agent disclosed by the invention, the corrosion action on the surface of metallic equipment is lightened through a low-foam and even no-foam surfactant and a corrosion inhibitor; an antibacterial agent plays a role in sterilizing and maintaining while retarding corrosion; through adopting the environment-friendly surfactant, the toxicity is lowered, and the pollution is reduced. The cleaning agent is suitable for cleaning the surface of the chemical equipment and is simple in preparation method and convenient in use.
Description
Technical field
The present invention relates to a kind of chemical industry surface cleaning agent, belong to clean-out system technical field.
Background technology
General mechanical equipment detergent includes high alkali liquid, although cleaning action obviously has sternly mechanical means
Heavy corrodibility, and general mechanical equipment detergent also includes permeate agent, permeate agent belongs to nonionogenic tenside, have certain hazardness to environment and human body, such as penetrating agent JFC series, its corrodibility is very strong, salkali waste band look difficulty reclaims, containing phenol in waste water, poisonous, substantially stop using; In addition, general clean-out system adopts foam type clean-out system mostly, although can the effective impurity such as wipe oil, foam type clean-out system can strengthen oxidation to metallic surface and corrosive nature, also causes certain infringement to equipment surface.
Matting be widely used in heat-exchange equipment in each industrial sector (as electric power, petrochemical industry, metallurgy and electronics etc.),
The incrustation scale on the surface such as the rolling mill scale of heat transfer equipment, cooling apparatus, iron and steel and other metallic substance and zone of oxidation and the cleaning of metal dirt.The heat power equipment (as boiler) of power department and the matting of chemical industry equipment are even more important.From socioeconomic angle, matting can reduce the fuel brought because of dirt and expend; From the angle of environment protection, decrease exhaust combustion gases and topsoil; From the view of security, the heat power equipment such as boiler and interchanger in use forms all kinds of dirt gradually, and the bad meeting of these dirt heat conduction causes boiler tube local temperature to raise, reduce the intensity of steel, thus cause the generation of pipe explosion accident, affect boiler and heat-exchange equipment operation, and the normal operation of equipment can be ensured by matting.
Summary of the invention
The object of the present invention is to provide a kind of chemical industry equipment surface cleaning agent, by low bubble or even the corrosive nature alleviating hardware surface without the tensio-active agent of alveolitoid and inhibiter, can being protected the surface of Substrate by antiseptic-germicide, reducing toxicity by adopting the tensio-active agent of environment-friendly and green.
To achieve these goals, technical scheme of the present invention is as follows.
A kind of chemical industry equipment surface cleaning agent, forms by the composition of following masses number is composite: anhydrous sodium metasilicate 10 ~ 20 parts, zellon 10 ~ 25 parts, sucrose fatty ester 10 ~ 25 parts, hydroxy ethylidene-diphosphate 10 ~ 30 parts, imidazolinium betaine 10 ~ 25 parts, termil 3 ~ 5 parts, tolyltriazole 2 ~ 4 parts and deionized water 50 ~ 150 parts.
Further, above-mentioned clean-out system preparation method is as follows:
(1) at room temperature anhydrous sodium metasilicate, zellon, sucrose fatty ester, hydroxy ethylidene-diphosphate are joined in deionized water, fully stir, form initial soln;
(2) add imidazolinium betaine, termil and tolyltriazole in obtained solution in step (1), be warming up to 40 ~ 80 DEG C, stir;
(3) above-mentioned solution is cooled to room temperature, namely obtains this product.
This beneficial effect of the invention is: clean-out system of the present invention is by low bubble or even the corrosive nature alleviating hardware surface without the tensio-active agent of alveolitoid and inhibiter, while delaying corrosion, also there is degerming and effect that is maintenance by antiseptic-germicide, toxicity is reduced, decreasing pollution by adopting the tensio-active agent of environment-friendly and green.In the present invention, using anhydrous sodium metasilicate as main solvent, anhydrous sodium metasilicate is a kind of industry cleaning link agent aid.It is also the important composition composition of the multiple clean-out system such as a kind of metal cleaner, heavy greasy dirt detergent, petroleum pipe line dredging cleaning agent, bottle milk bottle cleaning agent, and strong detergency, has again antiseptic and rustproof effect.This clean-out system is applicable to cleaning for chemical industry equipment surface, and preparation method is simple, easy to use.
