摘要:
The invention relates to a method for producing, from a waste comprising plasterboard elements (3, 4), an adsorbing granular material (7) containing at least 70% dihydrate calcium sulfate, comprising the steps of selecting (202) a fraction (4) of said plasterboard elements (314) formed by granules (6) having a diameter ranging between a preset minimum value and a preset maximum value; drying (203) said fraction (4) or said plasterboard elements (3, 4) at a preset temperature not exceeding 70 °C. Furthermore, the invention relates to a plant for producing (1), from a waste comprising plasterboard elements (3, 4), an adsorbing granular material (7) containing at least 70% dihydrate calcium sulfate, comprising sieving means (30) suitable to separate a fraction (4) of said plasterboard elements (3, 4) formed by granules having a diameter ranging between a preset minimum value and a preset maximum value, drying means (50) of said fraction (4) or of said plasterboard elements (314) at a preset temperature not exceeding 70 °C. Furthermore, the invention relates to an absorbing granule (300, 7, 9, 19, 29) comprising a core (303) which is formed by a fragment of waste of plasterboard panel, containing at least 70% of dihydrate calcium sulfate, said core having a diameter ranging between a preset minimum value and a preset maximum value.

The present invention provides a technique for prolonging the working time and setting time of a calcium sulfate hemihydrate paste by mixing calcium sulfate hemihydrate powder with an aqueous solution containing phosphate ions, so that the paste is suitable for operation and the resultant hardened calcium sulfate dihydrate block from the paste has an improved mechanical strength.
摘要:
Die Erfindung betrifft ein Bettmaterial für einen Stallboden für Nutztiere. Das Bettmaterial umfasst Lignocellulose, Calciumcarbonat und wahlweise ein Additiv, welche für alle Haltungssysteme Im Nutztierbereich geeignet ist. Das erfindungsgemäße Bettmaterial sorgt für eine extrem schnelle und effiziente Trocknung. Zudem verhindert es den Eintrag von pathogenen Keimen und steigert dadurch die Tiergesundheit im Stall und deren biologische Leistungsfähigkeit. Durch Zugabe von Additiven kann günstigenfalls der Produktionsprozess maßgeblich verbessert und somit die Wirtschaftlichkeit erhöht werden.
摘要:
Disclosed is a litter for animals, which can reduce the amount of ammonia generated from a urine excreted from an animal. Specifically disclosed is a litter for animals, which comprises multiple granules, wherein each of the granules comprises: particles each comprising an inorganic porous material; silica gel; and an inorganic binder for integrally binding the particles and silica gel to each other.
摘要:
An animal litter composition that includes geopolymerized ash particulates having a network of repeating aluminum-silicon units is described herein. Generally, the animal litter is made from a quantity of a pozzolanic ash mixed with a sufficient quantity of water and an alkaline activator to initiate a geopolymerization reaction that forms geopolymerized ash. After the geopolymerized ash is formed, it is dried, broken into particulates, and sieved to a desired size. These geopolymerized ash particulates are used to make a non-clumping or clumping animal litter. Odor control is accomplished with the addition of a urease inhibitor, pH buffer, an odor eliminating agent, and/or fragrance

Gegenstand der vorliegenden Erfindung ist ein Verfahren zur Herstellung eines Tierabfall absorbierenden Streumittels für Haustiere, wonach Körner eines Ausgangsgranulates vorgegebener Körnung mit einem pulverförmigen tonmineralischen Absorptionsmittel unter Flüssigkeitszugabe gemischt und anschließend getrocknet werden. Die entstehenden Fertiggranulatkörner sind mit einem Kern aus dem Ausgangsgranulat und einen umhüllenden Mantel aus der Absorptionsmittelbeschichtung ausgerüstet. Die solchermaßen hergestellten Fertiggranulatkömer weisen ein Schüttgewicht von mehr als 500 g/l auf.
摘要:
The invention relates to a heatable floor for livestock stalls comprising a plurality of hollow, right-angled plate elements whose hollow spaces are filled with a heat transfer fluid and can be heated by means of heating lines (11) running through said hollow spaces, wherein each plate element comprises one upper shell (1) having an inlet opening (5) and forming a standing surface for the livestock and one lower shell (7) supporting the upper shell (1), said shells being connected to one another liquid-tight at their edges and having means for suspending carriers and being supported on one another by supports (6, 9) that run through the hollow space. In order to enable filling of the plate element without bubbles in said floor with increased stability of the plate element, the invention proposes that the supports be formed by laterally open pipe nozzles with round or cornered cross-sections, at least in the region adjacent to the upper shell (1) from below, the lateral openings of said pipe nozzles all being aligned to a filling opening (5) located on the edge of the upper shell (1).
