Hydrolysis cleaning system refers to a cleaning process that utilizes the chemical reaction of hydrolysis to break down & remove polymer from surfaces or equipment. This system is commonly used in industrial settings, such as in the cleaning of heat exchangers, boilers, condensers, filtration elements and other equipment that may accumulate deposits. The principle of Vacuum cleaning furnace is based on the property that high molecule of synthetic fiber, isolated from air, is to be molten when the temperature reaches up to 300�?C, then melt polymers flow into waste collecting tank; when the temperature increases to 350�?C, up to 500�?C, polymer starts to degrade and exhaust out of furnace. TEG cleaning furnace: It uses the principle that polyester can be dissolved by glycerol (TEG) at its boiling point (at normal pressure, it is 285�°C) to achieve the purpose of cleaning. Ultrasonic cleaner: it is a device that emits vigorous mechanical vibrations into a liquid bath. This device achieves cleaning purposes through the use of sound waves. The sound waves create cavitations through the movement of the liquid bath, resulting in a detergent effect on the surface of the item being cleaned. It releases energy up to a level of 15,000 psi in order to loosen and eliminate dirt, grime, and impurities.
