The invention relates to the preparation of a porous silica-lime mass.n n n The silica-lime mass is obtained from an aqueous paste based on natural silica and slaked lime, at least doubly stabilized by mineral suspending agents, and reinforced by a fibrous type reinforcing agent consisting of cellulose fibers. very partially mechanically delignified, partially chemically delignified, partially chemically delignified and then refined by mechanical treatment, introduced in an amount of between 3% and 30% by weight relative to the solids.n n n Application of porous silica-lime materials to the filling of containers intended to store gases, in particular dissolved acetylene solutions. |
