Because the main components of cleaning agents are mostly nonionic surfactants, industrial cleaning defoamers require a targeted effect on the foaming of anionic surfactants.
Moreover, due to the large flow rate during metal cleaning, it is required that the metal cleaning defoamer can resist shearing.
Metal cleaning defoamer is added according to the formula, which has good compatibility.
Metal cleaning agents are generally alkaline, so metal cleaning defoamers should be alkali-resistant.
Finally, the defoamer for metal cleaning should be pollution-free and residue-free, which will not affect the appearance of metal.
