Geopolymer composite materials having low coefficient of thermal expansion are disclosed. The materials are useful in high temperature applications due to their low coefficient of thermal expansion and high strength. Also disclosed is a boron modified water glass geopolymer composition that is compatible with ceramic particulate material such as cordierite and fused silica. The geopolymer composite may be extruded to form structures such as honeycomb monoliths, flow filters or used as a plugging or skinning cement and may be fired at temperatures at or below 1100° C. Both the structures and the cement have high green and fired strength, a low coefficient of thermal expansion, and good acid durability. The cost of manufacturing objects using the material of the present invention is substantially reduced, in comparison with typically production methods of cordierite based bodies, due to the substantially shortened firing times.

A process and a device for atomization of a liquid extinguishing medium, in which the liquid extinguishing medium and a liquid inert gas are mixed in a mixing unit to form a liquid extinguishing medium mixture. The mixture is conveyed through a conduit to a distributing device such as extinguishing nozzles.

Igniter with safety unit, the safety unit comprises a push-button that is arranged at the backside of the gun body and partially protrudes out of the gun body, it can be pushed forward and return relative to the gun body; a elastic limit bar that is arranged at the side of the part of the ignition trigger that is towards the backside of the gun body, in natural condition, its end keeps against a barrier block which is integrated with the inner wall of the gun body; a button that is arranged in the push-button and protrudes out of the push-button, it can be pressed into the gun body and return. A protruding part arranged on the button's inner side protrudes towards a mid-portion of the gun body. In natural condition, the protruding part is towards the blank part, but when the push-button is in pushed up condition, the protruding part is near the end of the elastic limit bar and opposite to it. Thereby, if the button is pressed down, the protruding part of the button pushes the end of the elastic limit bar to make it distort and deflect from the barrier block on the inner wall of the gun body. The locking situation of the ignition trigger can be released. The apparatus can fire the flammable gas only by doing the two compound actions i.e. pressing down the button and pushing up the push-button simultaneously, thus further improving the safety of the ignitor.
