Dry ice blasting machine cleans with dry ice pellets shocking and swashing the dirt by the high speed. The solid dry ice pellets become gas state during the shock blasting. The dry ice pellets expand nearly 800 times in less than 0.001 seconds. Finally, the dry ice pellets sublimate and there aren’t any pollutants except dirt removed after dry ice cleaning. About dry ice blasting, many people still have doubts in many aspects, so our Shuliy machinery summarized some FAQs here for you, wish you have a better understanding both of the dry ice blasting and the dry ice blasting machine.
Q: What is Dry Ice Blasting?
A: Dry Ice Blasting is a new type of cleaning method with the advantages of non-abrasive, non-flammable and non-conductive, which is absolutely environment-friendly and can be widely used in many fields. The dry ice cleaning process should use the dry ice pellets which is usually with the diameter less than 3mm or use the dry ice blocks. Unlike other types of cleaning methods, dry ice blasting leaves no secondary waste to be cleaned up and does not utilize water or chemicals in the cleaning process.
Q: How does the dry ice blasting machine work?
答：在使用干冰喷射机之前，我们应该先将干冰粒放入干冰喷射机的容器中。然后干冰喷射软管将干冰颗粒高速喷射到物体表面，污垢会随着干冰颗粒的压实而迅速裂开。最后，当干冰升华时，它的体积会膨胀 800%，将污染物从表面上推出。
Q: Will dry ice blasting damage the surface being cleaned?
答：经过我们对干冰喷射的不断研究和学习，我们的干冰清洗技术已经得到调整和优化，使其能够清洁精致和粗糙的表面。这些范围从清洁电路板到清洁焊渣，而不会损坏表面。
Q: Can dry ice blasting clean online high temperature equipment?
答：干冰清洗最适合清洗高温在线设备。大多数污垢在高温下的水平低于环境温度下的水平，因此干冰清洗是一个不错的选择。在某些设备上，高温清洁可能比常温清洁快 3-5 倍。此外，在最后的干冰清洗之后，干冰升华到大气中，因此设备中不会留下任何清洗残留物。
Q: What is the amount of dry ice used in dry ice blasting?
答：根据我们的经验，我们的干冰出流量一般在清洗过程中调整为每分钟0.5~1.5公斤左右，但干冰喷射过程中总会有停顿和间歇的情况。我们通过50%计算每分钟1公斤的干冰流出量和清洗暂停时间。那么，一小时的干冰消耗量约为30公斤。
Q: Can dry ice blasting remove paint?
A: Yes, of course, the dry ice blasting can remove the paint. Dry ice blasting is aggressive enough to remove the paint but delicate enough to protect your investment. Cleaning with dry ice can clean grime, remove lead-based paint, and bring out original detail. Unlike abrasive or chemical restoration methods, dry ice blasting does not scratch or stain the surface. Instead, it uncovers the underlying surface and restores a structure to its original state. Dry ice blasting is easy to control and reaches the tightest cracks and corners without damaging surrounding objects.
