[Also in Division B5] In a method of producing linings or hot tops for ingot moulds, a pulp slurry is made from a fibrous organic material and other solid refractory ingredients, e.g. waste newsprint, silica flow, asbestos, quartz, or calcined dolomite, mixed with excess of water, a thermosetting binding agent, e.g. both a urea formaldehyde and a phenol formaldehyde resin, being added to the aqueous slurry which is then charged into a moulding vessel having a wall (e.g. of wire mesh) which is permeable only to the liquid medium, the binding agent being precipitated from the slurry either before or after charging to the moulding vessel, the liquid medium then passing through the permeable wall leaving behind a compacted mass of the solid constitents of the slurry which is subsequently heated to dry them and to cure the binding agent. The binding agent is precipitated by adjusting the pH of the slurry, e.g. to pH5 by the addition of a sufficient quantity of sodium or potassium bisulphate.

MANUFACTURING PROCESS OF NEW CELLULAR MATERIALS

Composite high temperature insulator

A composite high temperature insulator (A) includes a planar layer (10) having anisotropic thermal conductivity properties. A second planar layer (12) is formed from a rigid insulation material, such as a carbonized mixture of carbon fibers and a binder. The second layer is coextensive with the first layer and is preferably bonded thereto by a carbonaceous cement (44). When used to insulate a heat source, such as a furnace (50), convective heat is directed back to the source by the reflective surface (16) of the inner, anisotropic layer (10). Heat which enters the anisotropic layer is dissipated evenly through the plane of the layer along a plurality of heat paths defined by a plurality of layers (14) of flexible graphite. Accordingly, heat which reaches the outer, second layer (12) results in fewer hot spots than occur with a conventional rigid insulation material, thereby reducing the total amount of insulation material required to achieve a desired level of thermal insulation.

Phenolic resin compositions

PHENOLIC RESIN COMPOSITIONS ABSTRACT The present invention is directed to a phenolic resin composition suitable for use in bonding refractory materials, such as sand, in the production of foundry moulds and cores and also in treating subterranean formations. The phenolic resin composition comprises an esterified phenolic compound, a phenolic novolak resin and a base, which will react to provide final cure in the presence of water or other polar solvent. The composition, once reacted, will bond granular refractory materials. The esterified phenolic compound contains at least one esterified methylol group positioned ortho or para to a phenolic hydroxyl group or an esterified phenolic hydroxyl group. Included within the invention are anhydrous precursors to the reactive phenolic resin composition and also foundry moulding compositions which incorporate the reactive phenolic resin compositions. Other embodiments of the invention include methods for making foundry moulds and cores and methods for curing the reactive phenolic resin composition.

Mineral-resin matrix

Abstract of the Disclosure This invention relates to a mineral-resin matrix useful as a mould-ing composition or as a putty or binder for combining coarser mineral par-ticles to produce articles or semi-manufactures having excellent mechanical properties, such as high strength. The matrix of the invention consists mainly of mineral particles coated with a minor amount of a resin. The mineral particles preferably used are crystallized glass, possibly in combina-tion with other particles having rough surfaces such as sand, ground cement clinkers, ground glass, ground tiles and bricks, and similar materials, poss-ibly in admixture with particles of less hard minerals such as limestone, talc, gypsum, pumice, dry clay, china clay and the like. The particle size of the mineral can be varied to suit the use. For most purposes a particle size of from 0 to 150 µm has proved advantageous. Other particle sizes can be used, such as up to 250 µm. Particles having an ideal fineness characteristic are preferred.
