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.
- Banyaknya kotoran dan sulitnya benda yang akan dibersihkan juga mempengaruhi biaya pembersihan dry ice. Untuk objek dengan kotoran tebal dan cakupan kotoran yang luas, kebutuhan daya pembersih es kering akan meningkat, sehingga biayanya pun akan meningkat.
- Pemilihan spesifikasi es kering pada saat pembersihan juga akan mempengaruhi biaya. Harga bubuk es kering memang murah, namun konsumsinya banyak. Efek pembersihan es kering 3mm adalah yang paling cocok untuk dibersihkan.
Dry ice blasting principle
1. Kejutan termal: perbedaan suhu antara kontaminan dan permukaan benda (dampak dingin -79°C), permukaan kotoran dengan cepat didinginkan hingga -79°C oleh partikel es kering, mengakibatkan kotoran membeku dan rapuh , dan daya rekat pada permukaan yang dibersihkan menurun tajam.
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.
