With the continuous advancement of industrial cleaning technology, dry ice cleaning machines, as an efficient and environmentally friendly cleaning equipment, have been widely used in many fields. However, when using dry ice cleaning machines, we also need to pay attention to some key issues to ensure the safety and effectiveness of the operation. This article will introduce in detail the precautions for using dry ice cleaning machines from the aspects of equipment preparation, operation process, safety protection and subsequent treatment.
1. Precautions in the equipment preparation stage
1. Choose the right dry ice cleaning machine: Different models of dry ice cleaning machines have different powers, cleaning capabilities and applicable ranges. When choosing equipment, you need to choose a suitable dry ice cleaning machine based on specific cleaning requirements, such as the material, size, type and degree of stains on the object being cleaned.
2. Check the equipment status: Before use, the dry ice cleaning machine should be thoroughly inspected, including the power supply, gas source, nozzle, dry ice supply system, etc., to ensure that the equipment is in good condition without damage or leakage.
3. Prepare sufficient dry ice: Dry ice is the key cleaning medium of dry ice cleaning machine. Sufficient dry ice needs to be prepared before use and its quality must meet the requirements.
2. Precautions during operation
1. Wear protective equipment: Since dry ice will produce low-temperature gas during the vaporization process, operators need to wear protective equipment such as gloves, goggles, and protective clothing to prevent low-temperature gas from causing damage to the skin and eyes.
2. Control the dry ice blasting pressure: The blasting pressure of the dry ice cleaning machine is an important factor affecting the cleaning effect. The operator needs to adjust the appropriate blasting pressure according to the material and degree of stains of the cleaning object to avoid damage to the cleaning object.
3. Pay attention to the spray angle and distance: When spraying dry ice, you need to pay attention to the spray angle and distance. Generally speaking, the spray angle should be perpendicular to the surface of the cleaning object and the distance should be moderate to ensure that the dry ice can fully cover the stains and produce sufficient peeling force.
4. Avoid long-term continuous use: Long-term continuous use of dry ice cleaning equipment may cause overheating or damage. Therefore, it is necessary to arrange time reasonably during use to avoid long-term continuous use.
5. Pay attention to the consumption rate of dry ice: During use, you need to pay close attention to the consumption rate of dry ice. If the dry ice is consumed too quickly, there may be problems such as leakage or nozzle blockage in the equipment, which need to be checked and handled in time.
