Dry ice cleaning has been well known, and dry ice washing machines have been widely used in various fields. Many customers will consider that the use of dry ice cleaning technology saves labor and time compared to previous cleaning methods. Is the cost of dry ice cleaning high?

The cost of dry ice blasting includes the following aspects:
- First, you need to buy or rent a dry ice cleaning equipment according to your needs.
- A quantidade de sujeira e a dificuldade do objeto a ser limpo também afetam o custo da limpeza com gelo seco. Para objetos com sujeira espessa e grande cobertura de sujeira, os requisitos de potência do limpador de gelo seco aumentarão, portanto o custo aumentará proporcionalmente.
- A seleção das especificações do gelo seco durante a limpeza também afetará o custo. O preço do gelo seco em pó é baixo, mas o consumo é grande. O efeito de limpeza do gelo seco de 3 mm é o mais adequado para limpeza.

Dry ice blasting principle
1. Choque térmico: a diferença de temperatura entre o contaminante e a superfície do objeto (impacto frio de -79 ° C), a superfície da sujeira é rapidamente resfriada a -79 ° C por partículas de gelo seco, resultando em sujeira congelada e fragilizada , e a adesão à superfície a ser limpa diminui acentuadamente.

2. Mechanical kinetic energy: Dry ice particles impact the surface of the dirt at high speed. Usually, the speed of dry ice exceeds the speed of sound. Dry ice pellets have a low hardness at high speeds (Mohs scale of 2) and do not damage the surface of the object being cleaned.
3. Physical Sublimation: Dry ice particles sublime upon contact with the surface to be cleaned, the dry ice will change from solid to gaseous. The volume of dry ice pellets is increased by 800 times during the dry ice cleaning. This explosion does not destroy the surface being cleaned, but the dirt is removed by being blown away. The dry ice particles carry away the contaminants and cause them to fall off the surface of the object without damaging the surface. The entire process does not produce water and does not require chemicals.
