A method for manufacturing a high-density tableware article includes the following steps. The first step is providing a polyester resin composition including 45 to 78% by weight of a blend resin and 20 to 50% by weight of an inorganic filler. The blend resin includes PET resin and PBT resin and the content ratio of PET resin to PBT resin in the blended resin by weight is from 1:0.86 to 1:4.8. The next step is granulating the polyester resin composition to produce plastic granules. The final step is molding the plastic granules into a tableware article.

An appliance cabinet includes a structural envelope having an exterior surface and an interior surface that defines an insulating cavity, wherein the insulating cavity defines an at least partial vacuum. A plurality of silica-based agglomerates are disposed within the insulating cavity, wherein each agglomerate of the plurality of silica-based agglomerates includes silica-based powder insulation material that is water-densified and is at least substantially free of a material binder. A secondary insulation material is disposed within interstitial spaces defined between the plurality of silica-based agglomerates, wherein the plurality of silica-based agglomerates defines an interior structure that resists inward compressive forces exerted as a result of the at least partial vacuum defined within the insulating cavity.

In one aspect, the disclosed examples relate to a curable casting compound for producing plastics moulded parts. For example, the curable casting compound may include a binder component on the basis of a polymerisable monomer and a proportion of approximately 40% to approximately 85% by weight of one or more inorganic fillers. In one example, the casting compound includes an aluminosilicate as one of the inorganic fillers. Other examples are provided.

An engineered stone includes a light transmitting mother material (I) and a phosphorescent chip (II). The light transmitting mother material (I) includes about 7 wt % to about 12 wt % of an unsaturated polyester resin (A), about 88 wt % to about 93 wt % of a silica-containing compound (B) and about 0.01 part by weight to about 1 part by weight of an organic/inorganic pigment (C) based on about 100 parts by weight of the unsaturated polyester resin (A). The phosphorescent chip (II) includes about 8 wt % to about 15 wt % of an unsaturated polyester resin (A), about 85 wt % to about 92 wt % of a silica-containing compound (B) and about 2 parts by weight to about 10 parts by weight of a phosphorescent pigment (D) based on about 100 parts by weight of the unsaturated polyester resin (A).

A method is provided for preserving cooking oil in a food fryer which comprises contacting the oil in situ with at least one oil-permeable cement body which is a stand-alone block and which has been hydraulically hardened from a paste comprising (i) white OPC clinker, (ii) white OPC or (iii) a mixture of white OPC clinker and white OPC, wherein the porosity of the cement body, estimable from the difference between its water-saturated and dry weights, is 30-55%, pores in the body being oil receptive by virtue of low un-bound water content.

Provided is a ceramic filter for a beverage, the ceramic filter requiring a permeation time ranging from 3 seconds to 15 seconds in a case where 150 ml of hot water having a temperature of 90 C. is introduced, having a total pore volume of 0.230 to 0.270 cm.sup.3/g, and having a median pore diameter of 100 to 160 m. Also provided is a method for manufacturing the ceramic filter.

A self-cleaning composite material including the following composition: 50%-85% in weight of alumina trihydrate (ATH)-based mineral charges; 10%-30% of cross-linking polymer comprising polyester resin; photocatalytic Titanium Dioxide (TiO2) dispersed in the cross-linking polymer in a weight percentage from 0.05% to 5% with respect to the weight of the cross-linking polymer; compatibilizing agent for anchoring between the photocatalytic TiO2 and the cross-linking polymer, wherein the anchoring compatibilizing agent of the TiO2 is silane; and cross-linking monomers in order to obtain the reticulation of the cross-linking polymer by thermal or chemical polymerization.

A refractory composition is formed by preparing a set retarded fresh cementitious composition formed from a class C fly ash, a set retardant such as boric acid, and an alkali activator such as an alkali metal citrate salt, and contacting the set-retarded fresh cementitious composition with a pH regulator, such as an alkali metal hydroxide or alkali metal carbonate. The set retarded mixture provides workability and avoids equipment fouling caused by premature setting, while the alkali activator provides rapid setting when desired. The cementitious composition is shaped into a brick, panel, slab, concrete fire log, or the like and allowed to harden. The hardened cementitious composition can be heated to form a dried cementitious composition, and further heated to produce a high strength refractory composition. Fibers and/or aggregates may be included.

A ceramic filter 1 requires a permeation time ranging from 3 seconds to 15 seconds in a case where 150 ml of hot water having a temperature of 90 C. is introduced, has a total pore volume of 0.230 to 0.270 cm.sup.3/g, and has a median pore diameter of 100 to 160 m. A method for manufacturing the ceramic filter 1 includes a kneading process of obtaining a kneaded material in which 55 to 65 mass % of alumina, 6 to 12 mass % of bentonite, 6 to 10 mass % of water-insoluble organic fine particles, and 15 to 30 mass % of water are mixed, a primary molding process of molding a primary molded article by manually pressing the kneaded material against a filter mold, a secondary molding process of molding a secondary molded article by performing press working on the primary molded article molded in the primary molding process, and a firing process of firing the secondary molded article molded in the secondary molding process.
