Предлагается вододиспергируемая форма для изготовления отливок, причем форма содержит водонерастворимый материал в форме частиц и связующее средство для него, при этом связующее средство включает полифосфатные цепочки и/или борат-ионы. Изобретение также предлагает способ получения вододиспергируемой формы, включающий стадии создания водонерастворимого материала в форме частиц; смешения материала в форме частиц со связующим веществом, которое содержит полифосфатные цепочки и/или борат-ионы, причем цепочки и/или борат-ионы растворены в воде; формования или после, или в процессе стадии сечения материала со связующим веществом, смеси материала в форме частиц и связующего вещества в желаемую форму; удаления из смеси свободной воды. Полифосфатные цепочки могут быть получены из водорастворимого фосфатного стекла, а борат-ионы - из растворимого боратного стекла.A water-dispersible mold is provided for the manufacture of castings, the mold comprising a water-insoluble particulate material and a binder for it, the binder comprising polyphosphate chains and / or borate ions. The invention also provides a method for producing a water-dispersible form, comprising the steps of creating a water-insoluble particulate material; mixing the particulate material with a binder that contains polyphosphate chains and / or borate ions, the chains and / or borate ions being dissolved in water; molding, either after or during the stage of cross-section of the material with the binder, a mixture of particulate material and a binder into the desired shape; removing free water from the mixture. Polyphosphate chains can be obtained from water-soluble phosphate glass, and borate ions from soluble borate glass.
