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.
- 被清洁物体的污垢量和难度也影响干冰清洁的成本。对于污垢较厚、污垢覆盖范围较大的物体，对干冰清洗机功率的要求会增加，因此成本也会相应增加。
- 清洗时干冰规格的选择也会影响成本。干冰粉价格低，但消耗量大。 3mm干冰的清洗效果最适合清洗。
Dry ice blasting principle
1、热冲击：污染物与物体表面的温差（-79℃冷冲击），污垢表面被干冰颗粒迅速冷却至-79℃，导致污垢冻结脆化，并且对被清洁表面的附着力急剧下降。
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.
