DSJet Di history and introduce clean dry ice cleaning service

History DSJet Di Jie (Shanghai) Co., Ltd. specializes in the production cleaning equipment Dry ice cleaning machine dry ice manufacturing machine ice storage tank to provide various specifications of dry ice dry ice cleaning service cleaning supplies Di history of dry ice cleaning industry leader! Dry ice jet cleaning is the use of specially formulated by a compressor or the use of compressed air preparation plant itself produces compressed air system in the cleaning device into the ready-made dry ice pellets, compressed air driven, high-density dry ice pellets or powder to be cleaned with compressed air impact the surface, and thus play a cleaning role. And grit, sand and spray spray plastic soda similar to dry ice blasting medium dry ice pellets in a high pressure gas stream to accelerate the impact of surface to be cleaned. Dry ice cleaning is unique in that the dry ice pellets in the moment of impact vaporized. Momentum dry ice pellets disappear in the moment of impact. Rapidly between the dry ice pellets and cleaning the surface of the heat exchanger. Resulting in rapid sublimation of the solid CO2 into gas. Dry ice pellets in the thousandths of a second volume expansion of nearly 800 times. Since CO2 evaporate, dry ice cleaning process does not produce any secondary waste, leaving only clear need to collect clean off the dirt. Unlike other blast media, dry ice pellets temperature is very low (-78 ℃). Such a low temperature makes dry ice cleaning with unique thermal properties, mechanical properties affect the adhesion of dirt. Because of the dry ice particles and clean the surface temperature difference between the heat shock phenomenon occurs. Material temperature decreases, increased brittleness of dry ice particles can impact crusher dirt layer. The temperature difference between them in two different materials with different coefficients of thermal expansion would undermine the binding between the two materials. When removing non-metallic dirt from the metal material such heat shock phenomenon is most obvious. Even at very high speed direct impact cleaning surface, ice and sand is very small compared to the kinetic energy of the impact. This is due to the small ice hardness and impact instant vaporization. Since there is no wear, dry ice cleaning can be widely used in the cleaning of various materials. Dry ice blasting system, you need more than 5bar pressure, flow rate of 2m3 / min or more compressed air supply of clean, dry ice pellets fed by the mechanically compressed air pipeline, this pipeline dry ice pellets mixed with the air, accelerating from the nozzle out. Jet velocity of Mach values ??are typically between 1.7 to 3.0, depending on the design and the air pressure. Dry ice cleaning advantages of a PET cost savings of dry ice in the cleaning process direct evaporation, not cleaned cleaning media costs. Line cleaning, saving a lot of down time, no additional labor and production equipment, production is increased. 2, extended equipment life and sand, walnut shells, plastic pellets and other abrasive media is different, non-abrasive dry ice pellets. Dry ice cleaning PET molds without damage, no damage tolerance of the bearing and mechanical damage are not. In addition, the line cleaning to avoid the PET mold disassembly process of accidental injury. 3, the dry cleaning process with different steam and high pressure water cleaning, dry ice cleaning of wires, control components, switches are not damaged. After cleaning, the possibility of equipment compared with rusty water cleaning is also greatly reduced. In the food industry, the dry ice cleaning and water cleaning compared to greatly reduce the possibility of bacterial growth. 4, environmental safety CO2 is a non-toxic substance, in line with the United States Department of Agriculture (USDA), the Food and Drug Administration (FDA), Environmental Protection Agency (EPA) safety requirements. Cleaning with dry ice cleaning alternative to toxic chemicals, employees can avoid chemicals infringement fundamentally. Because CO2 is heavier than air, must ensure that the closed space or sink portion operation of dry ice cleaning ventilation, attention to safety. So, PET dry ice cleaning is the best choice, choose a dry cleaning service, of course DSJet, history Jie Di (Shanghai) Cleaning Equipment Co., Ltd.
