    摘要： One may obtain an excellent protective coating for a fabric made of heat-resistant fibers, in particular a fabric made of glass fibers like those used for the manufacture of filters in the metallurgical industry, when use is made, as a starting material, of a composition comprising an organic part made of sugar and a mineral part comprising colloidal silica and wollastonite. This composition allows thermoforming of the fabric and gives to the same a very strong protection and a rigidity. This is particularly interesting when the fabric is used for making a filter like those used during the casting of a liquid metal, especially liquid aluminum.

    摘要： This moldable refractory composition is intended to be used in the production of cast refractory pieces resistant to molten metals, especially molten aluminum. It comprises 8 to 25% by weight of an aqueous phosphoric acid solution having a concentration of phosphoric acid ranging from 40 to 85% by weight, with up to 50% of the primary acidic function of the acid phosphoric acid neutralized by reaction with vermiculite. It also comprises from 75 to 92% by weight of a mixture containing wollastonite and an aqueous suspension containing from 20 to 40% by weight of colloidal silica. The weight ratio of the aqueous suspension to the wollastonite within the mixture ranges from 0.5 to 1.2. The composition according to the invention is particularly interesting in that it can be unmolded within a very short period of time that is less than 2 hours and can be as small as 10 minutes.

    摘要： A process for manufacturing composite materials of high quality whatever be the respective amount, proportion and kind of constituents used in the starting mixture which comprises a binder made of two components capable of reacting with each other, at least one of these two components being in a liquid form, at least one filler, and reinforcing fibers, the binder being selected from the group of binders made of the following components: hydraulic cement and water; potassium and sodium silicate and water, colloidal silica and water; and organic resins and resin hardeners or catalysts. According to this process, all the liquid component of the binder is impregnated into an absorbing substance preferably consisting of vermiculite, which is compatible with the binder, the filler and the fibers. Then, the absorbing substance impregnated with the liquid component of the binder, is mixed with the solid component of the binder, the filler and the fibers in a mixer for a period of time sufficient to obtain the requested starting mixture in a semidry and homogeneous form, in which the fibers are entirely dispersed. The semidry mixture that is so obtained is then introduced into a mold and compressed under pressure for a period of time depending on the composition of the starting mixture and the predetermined properties of the composite material to be obtained. Last of all, the compressed material may be subjected to ageing and/or hardening as a function of the binder being used in order to obtain the desired composite material.
