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.
- Kiasi cha uchafu na ugumu wa kitu cha kusafishwa pia huathiri gharama ya kusafisha barafu kavu. Kwa vitu vilivyo na uchafu mzito na chanjo kubwa ya uchafu, mahitaji ya nguvu kavu ya kusafisha barafu yataongezeka, kwa hivyo gharama itaongezeka ipasavyo.
- Uchaguzi wa vipimo vya barafu kavu wakati wa kusafisha pia utaathiri gharama. Bei ya poda kavu ya barafu ni ya chini, lakini matumizi ni kubwa. Athari ya kusafisha ya barafu 3mm kavu ndiyo inayofaa zaidi kwa kusafisha.
Dry ice blasting principle
1. Mshtuko wa joto: tofauti ya joto kati ya uchafu na uso wa kitu (-79 ° C athari ya baridi), uso wa uchafu hupozwa haraka hadi -79 ° C na chembe za barafu kavu, na kusababisha uchafu uliogandishwa na uliotoka. , na kujitoa kwa uso kuwa kusafishwa kushuka kwa kasi.
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.
