Embodiment 1

[0030] The influence (mass fraction %) of the proportioning of embodiment 1 solvent on detergency

[0031] The carbon-deposited valves of gasoline engines were soaked in 6 kinds of decarburization liquid formulas for 2 hours, and then weighed with a pharmaceutical balance to calculate the value of the cleaning power. The cleaning power is the ratio of the weight of the parts before and after cleaning.

[0033] Dichloromethane

[0034] Table 2 Compounding of dichloropropane and tetrachloroethylene

[0035] Dichloropropane

[0036] Shown by table 1 and table 2, along with the increase of dichloromethane or dichloropropane composition, detergency has obviously improved, but the volatility of mixed solvent also increases relatively, when dichloromethane or dichloropropane content When the content of tetrachlorethylene is 40%, and the content of tetrachlorethylene is 30%, it has good cl...

Embodiment 2

[0037] The impact of embodiment 2 surfactant components on detergency (mass fraction %)

[0038] The carbon-deposited valves of gasoline engines were soaked in 6 kinds of decarburization liquid formulas for 2 hours, and then weighed with a pharmaceutical balance to calculate the value of detergency.

[0039] Table 3 The compounding of dichloromethane and tetrachlorethylene and sodium alkyl sulfonate

[0040] Dichloromethane

[0041] It is shown from Table 3 that the addition of the sodium alkylsulfonate component has a great influence on the detergency. As the relative content of the sodium alkylsulfonate component increases, the detergency increases first and then decreases. Therefore When the content of sodium alkyl sulfonate is 5%, it can provide good detergency without obvious foam.

Embodiment 3

[0043] Decarburization cleaning agent test formulation screening, including conventional decarburization formulations and formulations of the present invention, see Table 4.

Abstract

The invention discloses a decarburization cleaner. Perchloroethylene and methylen chloride or dichloropropane without flammable risk are used as decarburization solvents of the invention; on the basis of the permeability and dissolution of the solvents, the surfactant sodium alkyl sulfonate is compounded, thus promoting and improving the dirt-removing power, and trolamine is taken as antirusting agent without affecting the activity of the surfactant. The invention also discloses a formula and a preparation method of the decarburization cleaner. No heating or stirring is needed in using the invention, excellent using effect can be achieved by soaking at room temperature, energy consumption can be reduced remarkably. The pH value is neutral, thus having no corrosion on the surface of the material. The product has the characteristics of low toxicity, non-combustion and the like, thus the safety is improved greatly. The invention can be recycled only by simple filtering, thus saving using cost.

Description

technical field [0001] The invention relates to a cleaning agent, in particular to a decarburization cleaning agent, and belongs to the technical field of cleaning agents. Background technique [0002] In industrial production, mechanical equipment will accumulate carbon due to long-term use, and the cleaning work is more troublesome, such as diesel engine repair, heavy machinery manufacturing, diesel locomotives, diesel engine nozzles, train car nozzles, compressors, engines, pistons, and nozzles of fuel equipment, Stripping and cleaning of carbon deposits and dirt in various parts such as air compressors, circulating oil pipelines, and oil filters. Relevant parts need to be cleaned with a decarburizing cleaning agent. [0003] Carbon deposits are mainly composed of carbon particles and dust wrapped in asphaltene and tar. Asphaltene and tar can be removed by infiltration and dissolution with solvents. Although the molecular structure of carbon particles is relatively tigh...
