Asco and Daimler Partner for Dry Ice Blasting Technology in Motor Development
ASCO公司和戴姆勒公司合作发展用于发动机的干冰喷射清洗技术 在乘用车发动机的开发过程中，戴姆勒公司在德国
In the motor development of passenger cars at the works
in Untertürkeim, Germany, Daimler applies the dry ice blasting technology of the Swiss company Asco Carbon Dioxide Ltd.
It is essential that various motor components, such as
pistons, cylinder heads, oil pans and crankcases, are cleaned gently from silicone residues, oil, grease, ashes and other contamination or sealing compounds. Tese components must be cleaned gently after geometric measurement and test engineering so the measured data are not adulterated due to an abrasive cleaning method. Dry ice blasting technology is gentle and does not
damage the surfaces in any way. Te only alternatives are complex manual cleaning methods or cleaning with solvent, but these methods are more time-consuming. Even more important than timesaving is the assurance that the compo- nents are utterly clean after one cleaning process. Every double-measuring and secondary cleaning required due to an incompletely clean component means a loss. By using Asco’s dry ice blasting technology, the components are assured to be utterly clean after one cleaning process. Asco and Daimler have collaborated in the field of
tions with customers worldwide. Te product range includes CO2
CO2 vaporizers, CO2 storage tanks, CO2
production and recovery plants, dry ice blasting units, dry ice production machines, CO2 cylinder filling systems,
dosing
systems for water neutral- ization and various other CO2

and dry ice equipment.
ASCO has subsidiaries with production facilities in Switzerland, France and
the dry ice blasting technology for many years. Together, they are further developing and optimizing the process in an open dialogue. In one case, Daimler ran into trouble cleaning its pistons. Teir narrow ring groove could not be cleaned measurably with dry ice. However, together, Daim- ler and Asco found a solution thanks to a mounted crown of light on the Ascojet gun. Te ring groove can be primary cleaned with dry ice, while the rest of the contamination can be removed in the ultrasonic bath afterwards. ASCO is a provider of complete CO2
and dry ice solu-
Untertürkeim的工厂应用了瑞士ASCO二氧化碳公司的 干冰喷射清洗技术。
发动机的各类部件，如活塞、汽缸盖、油底壳和曲轴 箱都需要小心、轻柔地清洗去除硅残留物、油、油脂、 灰尘、污物及密封剂等，这是非常重要的。这些组件在 经过几何测量和工程测试后，也必须小心地清洗，所以 测得的数据不掺杂由于磨蚀性的清洁方法产生的杂物。 干冰喷射清洗技术是轻柔的，无论如何操作不会损 坏表面。唯一可替代的方案是复杂的手动清洗方法或用 溶剂清洗，但这些方法都更费时。比节约时间更重要的 是，经过清洗过程，部件都得到了彻底地清洁。 由于部件的清洗不彻底，每次的双测量和必须的二次 清洁都是损失。通过ASCO公司的干冰喷射清洗技术， 部件在清洗后可以保证完全清洁。 ASCO公司和戴姆勒公司在干冰喷射清洗技术领域的 合作已经很多年，他们以开诚布公的方式进一步开发和 优化此项技术。在一个应用案例中，戴姆勒公司在清洗 活塞时遇到了问题——活塞上的狭窄的环形沟槽不能使 用干冰量化清理，但是在戴姆勒公司和ASCO公司的协 作下，在ASCO干冰喷射枪上安置的环形光冠带解决了 这一问题。使用干冰可以基本清洗环形槽，其他的污物 可以通过后续的超声波清洗去除。 ASCO公司提供完整的二氧化碳和干冰解决方案，客 户遍布全球。产品范围包括：CO2生产和回收装备、 干冰喷射清洗单元、干冰制造设备、CO2气瓶充装系 统、CO2蒸发器、CO2 储存罐，水中和以及其 他各种二氧化碳和干冰 设备的CO2的定量系 统。ASCO在瑞士、法 国、新西兰的子公司均有 生产设施。
