ABSTRACT:
A hardened asbestos-free, porous, calcium silicate filler material for an acetylene storage vessel is made by mixing quicklime with water to form a first mixture and at the same time mixing water, synthetic silica, cellulose fibers and ground quartz silica to form a second mixture. The first mixture is then added to the second mixture to form a third mixture. The third mixture is homogenized. Then a suspending agent is dispersed in the third mixture to form a fourth mixture. The fourth mixture is transferred into a cylinder to be filled and is cured under saturation steam pressure. Thereafter, the cylinder is dried. A gas storage cylinder so formed has a monolithic dry mass filling a metal shell. The mass has a porosity of about 88 to 91% and a density in the range of 250 g/l to 270 g/l.
