Problems solved by technology

Conventional cleaning agents will produce a large amount of foam when spraying at room temperature or heating and high pressure, which reduces the cleaning effect and easily causes environmental pollution. Therefore, people will add a sufficient amount of defoaming agent to the cleaning agent, such as changing Defoamers such as non-toxic polyether, these defoamers can inhibit the generation of foam and avoid the harm of a large amount of foam
In actual use, it has been found that conventional cleaning agents have more and more chemical components and a large amount of surfactants, resulting in more and more serious organic pollution, and looking for a way to reduce the amount of surfactants can also improve the cleaning effect. A cleaning agent that cleans, reduces loss, and has a wide range of applications has important environmental significance

Abstract

The invention discloses an industrial cleaning agent containing a gemini structure surfactant and a preparation method. The industrial cleaning agent comprises an auxiliary agent, a dispersing agent, a complexing agent, a surfactant, a solubilizer, a cleaning additive and water. The dosage of the gemini surfactant is smaller (1-3%), the gemini surfactant has good capacity of improving the water flooding recovery efficiency and is obviously superior to that of a corresponding single-chain surfactant, the recovery efficiency improving effect of the gemini surfactant is correspondingly improved along with increase of the dosage of the gemini surfactant, and when the concentration of the gemini surfactant is only 500 mg / l, the water flooding recovery efficiency can be improved by 6.45%.

Description

technical field [0001] The invention belongs to the technical field of industrial cleaning agents, in particular to an industrial cleaning agent containing a gemini structure surfactant and a preparation method thereof. Background technique [0002] Cleaning agent is a commonly used preparation in industrial production. It is used to clean oil and other pollutants on metal surfaces. Its components generally include surfactants, and the cleaning ability of preparations can be improved by surfactants, such as the commonly used fatty alcohol polyoxyethylene. Ether surfactants, etc., the amount of surfactant added in the preparation is 5-10%. Conventional cleaning agents will generate a large amount of foam during normal temperature spraying or heating and high-pressure spraying, which reduces the cleaning effect and easily leads to environmental pollution. Therefore, people will add a sufficient amount of defoaming agent to the cleaning agent. Defoamers such as polyethers can ...
