Dry ice is the solid form of carbon dioxide. it's used primarily as a cooling agent. its advantages include lower temperature than that of water ice and not leaving any residue ( other than incidental frost from moisture in the atmosphere ). it is useful for preserving frozen food, ice cream, etc., where mechanical cooling is unavailable Dry ice sublimates at -78.5° (-109.3°F) at earth atmospheric pressure.HOW is Dry Ice Made ?
It is manufactured by compressing and cooling gaseous CO2 under high pressure to initially produce liquid CO2. the liquid is then allowed to expand under a reduced pressure to produce CO2 snow, and finally the snow is compressed by a hydraulic press into convenient Dry Ice blocks, slices or pellets. the density of the compressed CO2 snow depends on the applied pressure and the pressure time. the density of the Dry Ice block can reach 1.56g/cm3 as a muximum at temperature of -78.64°C. we can manufacture our Dry Ice using the world's leading manufacturing equipment, after all, the premier quality at our dry ice can only be achieved through manufacturing under such high densities.
Dry ice blasting is a revolutionary blasting method that uses small, compact dry ice pellets as the blasting materials. the dry ice pellets are accelerated in a jet of compressed air similar to that used in traditional blasting methods. Dry ice blasting is designed to replace high-pressure hosing and other traditional blasting methods that use materials such as sand, glass and plastic as abrasive agents. In addition, however, a wide range of other cleaning methods that involve the use of hazardous chemicals, solvents, etc., can with advantage be replaced by dry ice blasting. the unique features of dry ice as a blasting material is that it vaporises on contact with the surface to be cleaned. Treated surfaces are therefore left dry and clean, without residues of detergents or blasting materials. As the process is completed dry and non-conductive, dry ice blasting can be used where other methods are unsuitable. for example, electric motors and equipment with electric, pneumatic or hydraulic components can be cleaned direct using dry ice blasting. the system produces no waste products. Only the coating that has been removed remains to be disposed of, and this can usually be swept or vacuumed from the floor beneath the treated object. Dry Ice Blasting is ideal for removing coatings such as adhesives, varnish, oil, grease. coal dust, soot, mould release agents and bitumen - to name but a few of the materials we remove daily using the process. Dry ice blasting will often allow a company's production equipment to be cleaned while in operation without the need for dismantling and costly downtime. Dry ice blasting is non-abrasive, and surfaces are therefore treated gently. the system can thus be used on easily-damaged surfaces like nickel, chromium and soft aluminium. the process is dry, and no waste materials are produced. this means that cleaning can be carried out even during short production shutdowns.WHO CAN USE DRY ICE BLASTING ?
Dry ice blasting is ideal for removing coating such as adhesives, varnish, oil, grease, coal dust, soot, mould, rust inks, dyes, release agents and bitumen - to name but a few of the materials we remove daily using the process. No detergents or blasting materials is left after treatment. this makes the system highly suitable for industries that require a high degree - the food and pharmaceutical industries for example.
in brief. those industries looking for minimal shut-down time with zero left over waste.
Environment-friendly Dry ice is completely non-toxic. As no hazardous chemicals or solvents are used in dry ice blasting operators avoid being exposed to hazardous fumes and other dangers during cleaning. In contrast to high-pressure hosing polluted drain waste is avoided. Easy waste management the quality of waste material minimized because the blasting material vaporize.
