Potassium 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.
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.
By utilizing the free radical oxidizing substances generated during the decomposition of potassium persulfate, colored substances can be decomposed or converted into colorless substances, thereby achieving the goal of bleaching.
Potassium persulfate is also widely used in the food industry. It can be used for bleaching and decolouring of foodstuffs, such as white sugar and flour. In addition, potassium persulfate can be used for preservation and freshness of food, such as fruit juice, beer and so on.
Potassium persulfate also plays a vital role in many other industries, such as oxidizers, and initiators etc.
