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.
- 汚れの量や洗浄対象物の難易度もドライアイス洗浄の費用に影響します。汚れが厚く、汚れの範囲が広い対象物の場合、ドライアイスクリーナーのパワーの要件が増加するため、コストもそれに応じて増加します。
- 洗浄時のドライアイス仕様の選択もコストに影響します。ドライアイスパウダーは価格が安いですが、消費量が多いです。 3mmドライアイスの洗浄効果で洗浄に最適です。
Dry ice blasting principle
1. 熱衝撃: 汚染物質と物体の表面との温度差 (-79 °C の低温衝撃)、汚れの表面はドライアイス粒子によって急速に -79 °C まで冷却され、汚れが凍結して脆化します。 、洗浄される表面への付着力は急激に低下します。
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.
