Technical indicators of cleaning pre film agent

Cleaning pre film agent is a chemical substance applied to metal surfaces, which can be cleaned and treated before coating to improve the adhesion, corrosion resistance, and wear resistance of the coating. The technical indicators of the cleaning pre film agent include the following aspects:

Cleaning effect: The cleaning pre film agent should have a good cleaning effect, which can effectively remove dirt, oxides, and other impurities from the metal surface.

Surfactant content: Surfactants are an important component in cleaning pre film agents, which can reduce liquid surface tension, improve wettability and permeability, and thus promote the effectiveness of cleaning agents. The content of surfactant in the cleaning pre film agent should be appropriate, as high or low content can affect the cleaning effect and coating quality.

PH value: The pH value of the cleaning pre film agent should be moderate, usually between 5 and 9. High or low pH values can cause varying degrees of corrosion and damage to the metal surface, affecting the adhesion and corrosion resistance of the coating.

Effective component content: The effective component content of the cleaning pre film agent is an important indicator for evaluating its cleaning effect and economy. Usually, the higher the content, the better the cleaning effect, but it can lead to increased costs and wastewater generation.

Environmental performance: The cleaning pre film agent should meet environmental requirements, contain no harmful substances, and be able to be effectively treated and recycled after use. At the same time, the packaging and storage of cleaning pre film agents should also comply with safety and environmental standards.
