Gas mixing - Import export

Despite the increasing level of digitalization, an ever-increasing demand for paper and pulp products can be observed. However, a shift is taking place from print paper qualities to packaging paper and cardboard. The wide range of paper products requires a variety of production processes. These include mechanical and chemical processes which, depending on the form and variant, produce different pulp qualities. Stirring and mixing are essential unit processes in all types of paper and pulp production. Mixing tasks range from liquid/liquid or gas/solid/liquid mixtures, through mixing of complex liquids, and include mixing of chemically reactive components. Improving and optimizing mixing processes in the paper and pulp industry can lead to end product improvements; such as increased strength, improved luster, or significant energy or chemical savings.

This compact micro torch is ideally suited for melting the ends of sample tubes precisely and safely. As a very small flame can be adjusted, it is possible to melt the capillary precisely at a defined point without excessively heating the remaining capillary, as is the case with standard torches. The torch is operated with a hydrogen/oxygen or a propane/oxygen mixture, both of which provide a very hot flame that even permits quartz glass to be processed. This torch is an extremely versatile tool with which practically all types of glass can be processed – from simple flaming to highly complex tasks. Features of the micro torch Fine, concentrated needle-point flame High heating capacity Mixed-gas operation Two separate needle valves Complete with fine nozzles Torch length >130 mm (without nozzle) Operating principle The torch consists of a gas mixing chamber and two gas inlets, which are also suitable for aggressive media such as hydrogen and oxygen. Two needle valves at the...
