包装液 Silox · 数据表
General
Silox is a synthetic oil belonging to the group of polydimethyl siloxane. It is colourless and clear with a weak odour.
Application
Silox can be used in all RITTER Drum-type Gas Meters. As opposed to water as a Packing Fluid, Silox can be used under 0 °C. It also has a lower evaporation rate in combination with a viscosity similar to water. Because of this, the Packing Liquid level remains stable over a longer period of time. This leads to an improvement in the repeatability of measurement results, and in a reduction in the required frequency of Packing Liquid level monitoring.
The use of Silox is further recommended when the gas should remain dry or when the gas reacts with water.
Not suitable for wet chlorine gas and alkanes (methane, ethane, butane, pentanes).
