Description
Известны способы изготовлени изделий на оснаве гидроикиси :и тригидрокарбоната магни путем формовани .Methods are known for the manufacture of products using a hydroxy: and magnesium trihydrocarbonate by molding.
Недостатком изделий на основе гидроокиси магни и .тригидрокарбоиата магни , нолученных данным способом, вл етс Их ни-зка проч;ность .The disadvantage of products based on magnesium hydroxide and thrihydrocarboate magnesium, obtained in this way, is their low strength.
Предложенный способ лнше:; указанного недостатка. Сущность изобр.етени заключаетс н том, что издели , формованные из с еси иаст гидроокиси и тригидрокарбоната матшга, -аед-вергакггс теттловой обработке при температуре 100-120°.The proposed method lnshe :; specified disadvantage. The essence of the invention is that products molded from uyast iast hydroxide and trihydrocarbonate matte are edged vergakggstet processing at a temperature of 100-120 °.
Предло 4енный .снособ из; огозлени изделии заклюнатетс & следуюшем .Proposed by the method of; The product will be closed with the following.
Паста гидроокиси магни по.иучаетс путем ее осаждени -известковым молоком из обессульфаченной рапы с носледующей фильтрацией. Паста тригидрокарболата ло.чучаетс путем карбонизации пульпы гидрооки1си магни под давлением 5-6 атм -с последующим разложением бикарбоната .магни при нормальной температуре и .фильтрацией. Из смеси эти.х паст форл уетс изделие и суптитс на воздухе в течение 1--Ъ :суток, после чего оно подвергаетс тепловой обработке при температуре , равной 100-120°, в течеппе 2-4 час.Magnesium hydroxide paste is studied by precipitating it with lime-based milk from the unfloused brine with the next filtration. The trihydrocarbolate paste is absorbed by carbonizing the magnesium hydroxide slurry under a pressure of 5-6 atm, followed by the decomposition of magnesium bicarbonate at normal temperature and filtration. From the mixture of these paste pastes, the product and supittse in air for 1–5 days, after which it is subjected to heat treatment at a temperature of 100-120 °, in a flow of 2-4 hours.
Поллченные описанным способом издели :имеют предел пранности при .сжатии 130-170 кг1см.Products made in the described manner: have a limit of pranicity with. Compression 130-170 kg1cm.
При безобжигоЕой тепловой обработке смеси паст гидроокиси магни ;и тригидрокарбоната магни в присутствии влаги происходит образование новых соединений, осков ых карбонатов магни , которые .по ;прочности превосход т оба исходные вещества, подвергнутые аналогичной тепловой обработке раздельно.When the mixture of magnesium hydroxide pastes and magnesium trihydrocarbonate is heat treated without being burned in the presence of moisture, new compounds are formed that form magnesium carbonates, which are superior to both raw materials, subjected to similar heat treatment separately.
При внесении в с.месь во.юкнистого заполнител типа древесной ;стружки объемный вес изделий .может быть доведен до Q,5-0.,7 .г/лАWhen a bilious filler of wood type is introduced into the mixture of wood; chips, the volumetric weight of the products can be reduced to Q, 5-0., 7 .g / lA
№ 147125-2Использу дл получени изделий описанным способом отходы производства высококачественных магнезии, содержащие 20-30% тригидрокарбоната магни , можно получить разнообразные по свойствам строительные материалы.No 147125-2 Using production waste of high-quality magnesia containing 20-30% magnesium trihydrocarbonate using the method described above can be obtained with various properties of building materials.
Отличительной особенностью предложенного способа вл етс непосредственное получение изделий путем тепловой обработки при температуре 100-120° формованной смеси пасты гидроокиси магни и пасты, содержащей тригидрокарбонат магни .A distinctive feature of the proposed method is the direct production of products by heat treatment at a temperature of 100-120 ° C of a molded mixture of magnesium hydroxide paste and a paste containing magnesium trihydrocarbonate.
Предмет изобретени Subject invention
Способ изготовлени изделий на основе гидроокиси и тригидрокарбоната магни путем формовани , отличающийс тем, что, с целью повышени прочности изделий, их формуют из смеси паст гидроокиси магни и тригидрокарбоната магни , после чего подвергают тепловой обработке при температуре 100-120°.A method of manufacturing products based on magnesium hydroxide and trihydrocarbonate by molding, characterized in that, in order to increase the strength of the products, they are molded from a mixture of pastes of magnesium hydroxide and magnesium trihydrocarbonate, and then subjected to heat treatment at a temperature of 100-120 °.
