Problems solved by technology

At present, cleaning agents on the market are mainly divided into water-based cleaning agents, semi-solvent cleaning agents and solvent-based cleaning agents. The problem of eutrophic pollution caused by discharge into the environment is gradually revealed, and the biodegradability of some traditional surfactants is also poor, while the solvents selected for semi-solvent-based cleaning agents and solvent-based cleaning agents are mainly petroleum-based, fluorinated and fluorine-based. Although organic solvents such as carbon series have high decontamination efficiency, organic solvents generally have a low flash point, high toxicity, and are flammable, which is harmful to the human body. Large-scale storage in production is also a great safety hazard; family and industrial needs Relatively large heavy oil cleaning agents generally add a large amount of sodium hydroxide or potassium hydroxide and require high temperature to achieve the cleaning effect, but the cleaning agent is too alkaline, which will hurt hands and is more corrosive to the cleaning material
In short, there are more or less certain defects in the cleaning agents currently on the market, and most cleaning agents can only target a specific dirt or cleaning object. Multiple cleaning agents are needed to meet the needs of life, even if it is a single-function cleaning However, there is still the problem that the ability to clean heavy stains is not strong, such as removing heavy oil stains, blue and black ink, grass stains, etc. are still distressing things, especially for ink cleaning agents, most cleaning agents can only be removed very well The blue ink that is easy to fade and oxidize, and the blue-black ink contains ferrous tannate, which turns into iron tannate after oxidation, which will never fade. It is extremely difficult to remove it with commercially available cleaning agents
