摘要:
A mixture, dispersed in water, of approximately 95 % inert substances capable of forming a vitreous glaze and approximately 5 % cellulose fibres is prepared, kept thoroughly agitated, and fed to dewatering equipment - such as the flat suction table of equipment of the type used for paper making - to form a layer; a flocculating polyelectrolyte is added to the mixture; the layer formed is treated by dewatering and drying and by surface treatment for retention and fixing.
摘要:
A cement setting retarder comprising a polyester produced by the reaction of a polycarboxylic acid component containing a polycarboxylic acid having a main chain bearing 2 to 6 carbon atoms (e.g. maleic anhydride) with a polyol component containing a polyhydric alcohol bearing 2 to 4 carbon atoms or a condensate thereof. The unsaturated polyester is usable also as a polymerizable composition containing a polymerization initiator, a polymerizable vinyl monomer, and other components. The setting retarder may comprise particles of a cured unsaturated polyester. A setting retarder sheet can be formed by coating or impregnating a base sheet with a composition containing the retarder and a pressure-sensitive adhesive. It is possible to form patterns on the surface of a concrete product or to conduct exposed-aggregate finish thereon by forming given patterns in the form by using the retarder or sheet, placing a mortar composition thereon, and washing the surface of a set concrete to thereby expose an unset mortar.

Die gefärbten Ziergefäße und Ziergegenstände aus Keramik bestehen aus einem gebrannten, zumindest außen unglasiertem Ziergefäß oder Ziergegenstand aus Keramik, einer farbigen, aus wäßrigen Dispersionen aufgetragenen Farbschicht und einer aus Pulverlack aufgebrannten transparenten Schutzschicht.
摘要:
A glass powder adhesive sheet used for a surface coating of inorganic structures comprising ceramics, metals, glasses, etc., a glazed ceramic substrate such as a substrate of electronic circuit, etc. or a heat-resistant label, etc., which comprises a glass powder molding comprising as main components, a glass powder and a resin binder, and an adhesive layer having a thermal decomposition initiation temperature higher than that of the resin binder, provided on the surface of the glass powder molding.
摘要:
A number of porous substrates (10) are arranged alternately in contact with layers (12) forming metal-based composition sources. Each layer includes a major phase consisting of the metal-based composition and a minor phase capable of forming a structure for retaining and draining the molten metal-based composition. The load is heated to a temperature higher than the melting point of the metal-based composition so that said molten metal-based composition can migrate from each source into the substrate through the adjacent surface of the or each substrate adjacent to the source. The method is particularly suitable for delivering a silicon composition into a thermo-structural composite material, in particular a carbon-carbon composite material, for silicidising purposes.
摘要:
A polyester obtainable by a reaction of a polycarboxylic acid component comprising a polycarboxylic acid having 2 to 6 carbon atoms in the main chain (e.g. maleic anhydride), and a polyol component comprising a polyhydric alcohol having 2 to 4 carbon atoms or its condensate is used as a cement retarder. An unsaturated polyester may also be used as a polymerizable composition comprising a polymerization initiator, a polymerizable vinyl monomer or others. The retarder may be a particle of a cured product of an unsaturated polyester. A retardative sheet can be formed by applying or impregnating a composition comprising the retarder and a tacky adhesive to a base sheet. By forming a predetermined pattern with the use of the retarder or sheet in a form, depositing a mortar composition, washing a surface of the hardened concrete, and washing out uncured mortar, a figure or a washing finished surface is formed on a surface of a concrete product.
