Cleaning before sand blasting - cleaning agent degreasing

       Cleaning agent solvent is a large category with a wide variety, including two categories: inorganic cleaning and organic cleaning. But they are all formulated with surfactants and various auxiliaries and auxiliaries. When it washes the dirt on the surface of the object, it can change the surface activity of water and improve the decontamination effect. The cleaning agent generally has low surface tension and strong penetrating force, can penetrate into small gaps, and completely dissolve and remove attached dirt; low boiling point, high evaporation heat, suitable for steam cleaning, and can be self-drying after cleaning; waste liquid can be separated by distillation and recycled; The cleaning process and equipment are simple, the efficiency is high, and the operating cost is low;



      There are many cleaning agents suitable for degreasing, such as: room temperature degreasing agent, thermal oil furnace cleaning agent, water-based cleaning agent, heavy oil stain cleaning agent, etc. Among them, water-based cleaning agent is an industrial detergent, which is composed of surfactant and a small amount of additives, and has three forms of powder, paste and liquid, and is generally alkaline. The principle of water-based cleaning agent degreasing and cleaning is: the water-based cleaning agent and water are made into an aqueous solution, the surfactant molecules in the aqueous solution emulsify and decompose the oily dirt on the surface of the workpiece, and the water-soluble dirt on the surface of the workpiece is dissolved by water, so as to achieve The purpose of surface degreasing cleaning. Water-based cleaning agent degreasing is a degreasing cleaning method that has been rapidly developed in recent years. It replaces oil with water, and has the characteristics of energy saving, low cost, good labor conditions, safe use and low pollution. Commonly used water-based cleaning agents for degreasing and cleaning methods include dipping method, flushing method, steam method and ultrasonic method.
