Description
Vynález se . týká způsobu výroby stavebních a jiných - prvků, ' ' např. cihel, při kterém se působí tlakovou vodní parou na předem vylisovaný prvek.The invention is. The invention relates to a process for the production of building and other elements, for example bricks, in which a pressurized element is subjected to a pressurized steam.
Je znám způsob'výroby vápenopískových cihel, při kterém se na směs písku, diatomitu, popřípadě flotačního odpadu, po,slisování působí tlakovou vodní parou. Při . tomto způsobu se obvykle 10 % hmot..kvalitního vysoce'aktivního prachového nehašeného vápna smísí s pískem, diatomitem, popřípadě flotačním odpadem, podle předem stanovené zrnitostní křivky, načež ssna směs působí vodou až do vyhašení vápna. Směs se nechá odležet - 24 hod. a při tlaku 30,0 MPa se vylisují cihly-, . na které se působí vodní parou o tlaku 16 at. při teplotě 200.°C. poměrně vysoký.tlak - při lisování,- 't.j. 30,0 Mpa se volí proto, že se stoupajícím tlakem stoupá i pevnost hotových výrobků. - Každou dodávku vápna . je nutno kontrolovat zvláště z hlediska aktivity; pokles aktivity - vápna má za následek i pokles pevnosti vyrobených cihel pod požadovanou minimální - pevnost 10,0 MPa. Nevýhodou tohoto způsobu je v prvé řadě okolnost, že je nutno používat kvalitního, - vysoce aktivního vápna, jeho neustálá kontrola- a dodržení optimální zrnitostní křivky lisované směsi. Dále se využívá klasických materiálů jako je křemenný písek nebo diatomit a - pouze omezeně flotační odpad, jehož samotné použití naráží na značné obtíže, i když tento odpad obsahuje více než 50 % kysličníku křemičitého.It is known to produce sand-lime bricks in which the mixture of sand, diatomite and / or flotation waste is subjected to pressurized water vapor after compression. When. In this process, usually 10% by weight of high-quality, high-activity quick slaked lime is mixed with sand, diatomite or flotation waste, according to a predetermined grain size curve, after which the mixture is treated with water until the lime is extinguished. The mixture is left to stand for 24 hours and bricks are pressed at a pressure of 30 bar. treated with water vapor at a pressure of 16 at. at 200 ° C. om p ters of vysoký.tlak - when L Išová ck '-' i.e. 30.0 M p and p are chosen roto that increasing pressure increases the strength of the finished products. - Every supply of lime. it should be checked in particular for activity; decrease of activity - lime results in decrease of strength of produced bricks below required minimum - strength of 10,0 MPa. The disadvantage of this method is, first and foremost, the need to use high-quality, high-active lime, its constant control and adherence to the optimum grain size curve of the pressed mixture. Furthermore, conventional materials such as quartz sand or diatomite are used, and - only to a limited extent, flotation waste, the actual use of which is subject to considerable difficulties, even if the waste contains more than 50% silica.
Výše uvedené nevýhody odstraňuje způsob výroby stavebních a jiných prvků, - např. cihel, při * kterém - se působí tlakovou vodní parou na- předem vylisovaný prvek. Jeho podstata spočívá podle vynálezu v tom, že .se tyto prvky lisují ze směsi obsahující surovinu s uhličita:nem hořečnatým dekarbonizovaným - alespoň - z 20 % a nejmfaě 50 % hmot«-suroviny s - alespoň 50 % hmot, kysličníku křemičitého a hlinitého. Podle jednoho provedení vynálezu se použije odpad z tepelné úpravy magnezitových surovin - a - odpad vzniklý spalováním uhlí.The above disadvantages are eliminated by a method of manufacturing building and other elements, such as bricks, in which a preformed element is subjected to pressurized steam. The invention is characterized in that a hydroperoxide of these elements are pressed from a mixture containing the carbonate raw material with: h can not mount a C to T ym e d b ar to one zovaným i - l and ESPO least - 20%, and 50% h nejmfaě mo t «- raw materials - and l e s pon 50% by weight, silica and alumina. According to one embodiment of the invention, waste from the heat treatment of magnesite raw materials - and - waste generated by coal combustion is used.
Výhodou způsobu podle vynálezu je s-kutečnost, že lze použít nejen křemenný písek, diatomit, flotační odpad, ale- zejména odpadních produktů jako - je škvára, elektrárenský popílek a odpady - z tepelné úpravy magnezitových nebo dolomitických surovin. Přitom je tedy postačující použití pouhých odpadních - , surovin, t.j. - např. odpadu z tepelné úpravy magnezitových surovin a odpadu ze spalování uhlí.The advantage of the process according to the invention is that not only quartz sand, diatomite, flotation waste, but especially waste products such as slag, power plant fly ash and waste from heat treatment of magnesite or dolomitic raw materials can be used. Thus, it is sufficient to use only waste raw materials, i.e. waste from the heat treatment of magnesite raw materials and waste from coal combustion.
Pro objasnění způsobu podle vynálezu se - uvádí - příklad. Odpad z tepelné úpravy - magnezitových surovin, ve kterém byl uhličitan hořečnatý dekarbonizován z 50 - -%, a který obsahoval v použitém stavu 33- % hmot, kysličníku hořečnatého, vztaženo na neúplně dekarbonizovaný uhličitan hořečnatý, byl rozemlet na .- zrno pod 0,2 mm a smísen se škvárou, která byla rozemleta rovněž na zrno pod 0,2 mm. - Z této směsi byly vylisovány cihly při tlaku 24,0 MPa a podrobeny tlaku 1,6 MPa. vodní páry při teplotě 200 °C. Bylo dosaženo těchto h°dnot: při poměru 1 díl odpadu k 5 dílům škváry činila pevnost cihly 20,8 ’ MPa. Při -poměru odpadu ke ' škváře 1:3 činila pevnost 30,7 MPs. Nebyla vůbec stanovena optimální zrnitostní křivka a bylo lisováno při nižším tlaku než se používá při vápenopískových cihlách.An example is given to illustrate the method of the invention. Wastes from the heat treatment of magnesite raw materials in which magnesium carbonate was decarbonised by 50 - -% and which contained, as used, 33% by weight, of magnesium oxide, based on incompletely decarbonised magnesium carbonate, were ground to below 0, 2 mm and mixed with a slag which was also ground to a grain below 0.2 mm. - From this mixture bricks were pressed at a pressure of 24.0 MPa and a thickness below r oben battery 1, 6 and MP. D in the P and R at t y l ep I of 200 ° C. B y lo dos and Z e n o h about these no t ° d: a ratio of 1 part to 5 parts of waste slag bricks strength was 20.8 'MPa. With a waste ratio to the slag of 1: 3, the strength was 30.7 MPs. The optimum grain size curve was not determined at all and was pressed at a lower pressure than that used for lime-sand bricks.
Přesto bylo dosaženo vyšších hodnot, jak uvedeno. - Volbou optimálního složení směsi, např. škvára, popílek, magnezitový odpad, lze dosáhnout při tlaku 30,0 MPa a při stanovení optimální zrnitostní křivky ještě vyšších pevnostních hodnot. Jen pro úplnost se ještěNevertheless, higher values were achieved as indicated. - By selecting the optimum composition of the mixture, eg slag, fly ash, magnesite waste, even higher strength values can be achieved at a pressure of 30.0 MPa and an optimal grain size curve. Just for completeness, yet
211 917 uvádí, že z namátkově zvolené směsi: 1 díl magnezitového odpadu, 1 díl rozemleté škváry a 1 díl popílku po vylisování a působení tlakové vodní páry byly vyrobeny cihly o pevnosti 20,0 MPa.211 917 discloses that from a randomly selected mixture: 1 part magnesite waste, 1 part ground slag and 1 part fly ash after compression and pressurized water vapor were produced bricks with a strength of 20.0 MPa.
Podle statistických údajů produkuje dnešní průmysl v celém světě desítky milionů tun odpadů ze spalování uhlí, které se haldují a podstatně zhoršují životní prostředí. Rovněž magnezitový průmysl produkuje velké množství magnezitových, popřípadě dolomitových odpadů. Zužitkováním těchto odpadů způsobem podle vynálezu lze nejen významnou měrou přispět к ozdravění životního prostředí, ale současně vyrobit stavební a jiné prvky o vysoké Jakosti. Podle místa výskytu odpadních produktů lze volit vlastní složení směsi a výhodně použít i Jiných surovin než uvedeno, např. odpadu z výroby agloporitu л dále volit různé přísady, např. barvivo, přísady zlepšující tepelnou účinnost, omyvatelnost, ohnivzdornost apod.According to statistics, today's industry worldwide produces tens of millions of tons of coal-burning waste that is piling and significantly degrading the environment. The magnesite industry also produces large quantities of magnesite or dolomite waste. By utilizing these wastes by the method according to the invention, it is not only possible to make a significant contribution to the recovery of the environment, but also to produce high-quality construction and other elements. Depending on the location of the waste products, the actual composition of the mixture can be chosen and advantageously used other raw materials than mentioned, eg waste from agloporite production л further select various additives, eg dye, additives improving thermal efficiency, washability, fire resistance etc.
