Description
Существующие способы получени газогипса основаны на вспучивании гипсового раствора газами (углекислым, водородом, ацетиленом (.)- вщдел ющимис в результате реакций, происход щих IB растворе между добавками (мел, известн к, доломит, алюминиева пыль), введенными в гипс при его затворении.Existing methods for gas-gypsum production are based on the expansion of a gypsum solution with gases (carbon dioxide, hydrogen, acetylene (.) - as a result of reactions that occur in an IB solution between additives (chalk, lime, dolomite, aluminum dust) introduced into gypsum during its mixing .
Предлагаемый способ основан на вспучивании гипса газами сероводорода , что упрощает технологию изготовлени его.The proposed method is based on the swelling of gypsum with hydrogen sulfide gases, which simplifies the technology of its manufacture.
Отличительна особенность предлагаемого способа состоит в том, что гипс, получаемый размолом в мельницах гор чего помола или обжигом в сущильных барабанах, затвор етс водой с добавкой к ней серной , сол ной и прочих кислот в количестве 0,5-20% от веса гипса или сернокислых солей (1-5%), дающих с водой кислую реакцию. При ЭТО(М выдел етс сероводород, делающий гипсовые отливк И .пористыми.A distinctive feature of the proposed method is that the gypsum obtained by grinding in hot grinding mills or roasting in the stern drums is shuttered with water with sulfuric, hydrochloric and other acids in the amount of 0.5-20% by weight of gypsum or sulfate salts (1-5%), giving an acidic reaction with water. With IT (M, hydrogen sulphide is released, which makes plaster casts And is porous.
При размоле гипса в холодных мельницах с последующей варкой в котлах дл получени вспучивани к гипсу перед затворением водой с примесью кислот или солей добавл ют золу от сжигани каменных углей , вызывающую газообразование сероводорода и получение пористых отливок.When grinding gypsum in cold mills, followed by boiling in boilers to get swelling, ash from burning coal is added to the gypsum before mixing with water with an admixture of acids or salts, causing gassing of hydrogen sulfide and producing porous castings.
Объемный вес газогипса, получаемого на основе вспучивани гипса сероводородом, составл ет от 300 кг1м и выще, что зависит от количества добавки в раствор кислот и воды.The volumetric weight of the gas-gypsum obtained on the basis of the swelling of gypsum with hydrogen sulfide is from 300 kg 1 m and more, which depends on the amount of the additive in the solution of acids and water.
Предмет изобретени Subject invention
1. Способ получени газогипса, отличающийс тем, что гипс, получаемый размолом в мельницах гор чего помола, а также гипс, получаемый обжигом в сущильных барабанах, затвор ют водой с добавкой к ней серной, сол ной и других кислот или сернокислых солей, дающих с водою кислую реакцию.1. A method of producing a gas-gypsum, characterized in that the gypsum obtained by grinding in hot-grinding mills, as well as gypsum obtained by roasting in the original drums, is sealed with water with the addition of sulfuric, hydrochloric and other acids or sulfuric acid salts water sour.
№.92577№.92577
2. Прием выполнени способа п. 1, отличающийс тем, что гипс, получаемый размолом в холодных мельницах, предварительно смешивают с топочною каменно угольной золой, а затем затвор ют водой с примес ми кислот и солей, указанных в п. 1.2. Acceptance of the method of claim 1, characterized in that the gypsum obtained by grinding in cold mills is preliminarily mixed with furnace coal coal ash, and then closed with water with impurities of acids and salts indicated in paragraph 1.
