Product introduction:

Pickling inhibitor is an efficient pickling inhibitor combined with di-o-toluene thiourea, praziquantel and dimethylpyridine derivatives. When the adsorption group (hydrophilic group) reaches a certain density on the metal surface, it generates a corrosion-resistant adsorption film. The film formed by this chemical adsorption is relatively firm, so it still has a good corrosion-resistant effect at higher temperature. This product can inhibit acid mist and hydrogen embrittlement of metal during pickling, so that the metal can maintain the mechanical properties of the original material after pickling.
