PCB circuit board surface micro etching treatment, cleaning the copper surface, removing oil stains, and forming a certain roughness on its surface, thereby increasing the bonding force between the copper surface and various materials in the next process, such as chemical copper, electric copper, electric tin, dry film, green oil, organic film, etc.
At present, ammonium persulfate as a gel breaker is still the main product in underground oil reservoir fracturing additives. It can liquefy the gel within a certain period of time and be easily discharged, reducing the damage of fracturing fluid to the oil reservoir. Due to its high cost-effectiveness and good performance, it has been widely used, and some oil fields have begun to use sodium persulfate to achieve environmental protection and safety goals.
By utilizing the free radical oxidizing substances generated during the decomposition of ammonium persulfate, colored substances can be decomposed or converted into colorless substances, thereby achieving the goal of bleaching.
Ammonium persulfate acts as a coating additive to provide an oxidizing agent. During the curing process of the coating, ammonium persulfate generates reactive oxygen radicals through decomposition, and these radicals can trigger oxidation reactions in the coating, prompting cross-linking reactions between the coating molecules to occur. This cross-linking reaction improves the hardness and abrasion resistance of the coating, increasing its service life. Ammonium persulfate can also enhance the anti-pollution properties of coatings, and ammonium persulfate also plays an important role in improving the adhesion of coatings.
Ammonium persulfate also plays a vital role in many other industries, such as oxidizers, and initiators etc.
