In daily life, dry ice pellets are used in industries such as tire manufacturing, printing, and engine maintenance. They are mainly used as raw materials for dry ice blasting and cleaning, and are also widely used in industries such as refrigerated transportation, catering, and entertainment. However, many friends may not know how this type of pellet dry ice is manufactured. Below, Xinwantong Dry Ice will give you a brief introduction:
Firstly, the concept of dry ice is required. At room temperature, when carbon dioxide gas is pressurized to about 101325Pa, when a portion of the vapor is cooled to around -56 ℃, it will freeze into snowflake like solid carbon dioxide. The gasification heat of solid carbon dioxide is very high, at -60 ℃ it is 364.5J/g. When gasified under normal pressure, it can lower the ambient temperature to around -78 ℃ without producing liquid, so it is called “dry ice”.
The dry ice medium used in dry ice blasting cleaning is produced by a dry ice granulator to produce solid dry ice particles, which can be used immediately or stored in an insulated box for later use. These particles typically have a diameter of 3mm and a length of 2.5mm-10mm. In this method, high-pressure liquid CO2 is sprayed out of the pipeline and converted into snow like solid CO2. Snow like CO2 is extruded into dry ice particles through a mold by hydraulic pressure.
Dry ice pellets are a byproduct of industrial production processes, such as fermentation and petroleum refining, both of which produce byproduct CO2. The CO2 generated during these production processes is purified, hydraulically pressurized, and stored to produce dry ice for cleaning. When CO2 sublimates and is emitted into the atmosphere during the spraying process, no new CO2 is produced, only the original CO2 by-products are emitted, achieving the reuse of exhaust gas CO2 and benefiting humanity.
Our dry ice pellets are of high quality and come in a variety of specifications to meet the diverse needs of different industries. Whether you are using them for cleaning, stage smoke effects, or decorating dishes, we have dry ice pellets that meet our specifications. We produce and sell independently, with direct sales from manufacturers. The price is more reasonable and the product is more guaranteed.http://www.qdxwtgb.com
