Metal cleaners are mainly composed of surfactants and auxiliaries, so they have strong degreasing and cleaning capabilities, but surfactants can easily cause a lot of foam and affect the cleaning. Therefore, the foam of the cleaning agent should not be too much, and the cleaning agent defoamer can be added to control the foam and eliminate the excess foam.

The cause of foaming of metal cleaner
Surfactants and additives are the main components of cleaning agents.
1. Surfactant
Surfactants are generally aliphatic derivatives or aromatic derivatives of all aliphatic hydrocarbons, which have strong wetting, solubilizing and emulsifying abilities on the dirt. Such as oleic acid triethanolamine, alkyl phosphate, amide phosphate, phenol ether stinol ether, phosphate ester, fatty alcohol polyoxyethylene ether and so on.
2. Additives
Corrosion inhibitors are commonly used components in metal cleaners. The anti-rust and corrosion inhibitor cleans the metal surface to make the cleaning without corrosion and damage. The cleaning button makes the metal surface clean and bright and has a certain effect of corrosion and rust prevention. Common inorganic corrosion inhibitors include sodium nitrite, sodium nitrite, sodium carbonate, trisodium phosphate, disodium hydrogen phosphate, sodium silicate, ammonium carbonate, etc. Organic corrosion inhibitors include sodium benzoate, ammonium benzoate, phenylethanolamine, urea and so on. These corrosion inhibitors can be used alone, but they are best used in combination.
In addition, in order to facilitate metal cleaning, it is necessary to add a cleaning agent and defoamer for preparation. This is mainly because the surfactant in the cleaning agent easily causes a lot of foam.
Surfactant is a special molecule with amphiphilic structure. It has the characteristics of interfacial adsorption, orientation arrangement, micelle formation, etc., which can significantly change the properties of the interface, so that the surfactant has washing, wetting, penetration, dispersion, emulsification, Solubilization, foaming, foam stabilization, softness, antistatic, anticorrosion, sterilization and other functional properties. Cleaning agent foaming can help decontamination, but too much foam needs to be controlled, which requires the use of defoamers.

Cleaning agent defoaming program
In order to facilitate the operation of metal cleaning, a low-foam or non-foam state is generally required. Cleaning agent defoamer can achieve this effect. The cleaning agent can not only achieve a good cleaning effect through the wetting and dispersing effects of the surfactant, but also can control its foam to eliminate excess foam.
The Nanhui defoamer manufacturer develops and sells cleaning agent defoamers with good defoaming performance in view of the easy foaming characteristics of cleaning agents. It is a type of compound metal cleaning defoamer.
