Environmentally friendly cleaning agent processing, precision electronic environmentally friendly cleaning agents, industrial cleaning agents, ultrasonic cleaning agents

The industrial cleaning industry of Hong Kong Lian Environmentally Friendly Cleaning Agent is a branch industry of the cleaning industry and an important auxiliary industry serving industrial production and manufacturing. However, for many years, the development technology of my country's industrial cleaning industry still lags behind foreign countries. Whether it is large-scale cleaning equipment or industrial cleaning solvents, they are mainly imported from abroad. However, as the Chinese government begins to pay more attention to environmental protection and is committed to improving air quality, some companies that focus on the production and research and development of environmentally friendly industrial cleaning agents have found development opportunities.
The cleaning principle of hydrocarbon cleaning agents is simply based on the solubility of the solvent. The degreasing mechanism based on the solubility of grease or oily contamination is the principle of similar miscibility. Hydrocarbons such as kerosene easily dissolve heavy oil, and other hydrocarbons are easily miscible with similar halogenated hydrocarbons (carbon tetrachloride, trichloroethane, etc.). This is also based on the fact that water can be miscible with compounds that have similar structures to water, such as (lower fatty acids) (lower alcohols).
The solubility between dissimilar liquids is closely related to surface tension and interfacial tension.
For example, the surface tension of solvents such as benzene cycloalkanes is not much different from the surface tension of tar lubricating oil, and the interfacial tension values between the two are similar and easy to dissolve each other.
Regarding the solubility of solvents in grease or oily dirt, during the cooling process of solutions of different solvents at a certain temperature, the lower the temperature at which the solute separates, the greater the solubility of the solute.
Generally, the value of hydrocarbon cleaning agents is ~. This value is consistent with the value of processing oil (~), so it is easy to dissolve and has high cleaning power. But it is far from the value of resin, so it is not easy to attack these materials. At the same time, for resin-containing dirt, the solubility of alcohol is poor and the cleaning effect is not good.
The value of cleaning agent selection can be used as an indicator, but it is dangerous to only use numerical values as a judgment. Actual contaminated oil must be used for cleaning performance experiments to evaluate.
