Description

Podstawa sposobu wyrobu maisy do mo¬ deli rzezbiarskich, bedacego przedlmibtem wynalazku nilniejszeglo, jest to, ze istnieja¬ ce w gruzie gjjpsowym krzemiany glinu i kwlasu krzemowego najdaja sile wybornie do przygotowlaniia zajprawy bez dodawania srodka wijacego. Podlug wynalazku ni¬ niejszego przediewszystkiem przed lub pod¬ czas spalania w zwyklym piecu nagroma¬ dza sile z gruzem gilpsowym mielone wiaprio, zawierajace kwas weglowy talk, ze przy dlznalabiii ciepla spalania' sie gruzu, wy¬ dziela si^ kwiais weglowy z zawierajacego go wapna i powlsitaje wialpno zrace, Wów- ctzais gasi sile powstaljace z tej mieszaniny zuzle zapomoca wody lub pary wodnej, przez co wapno zrace przechodzi w wo- dziian wapnia. Cieplo pozostiale w zuzlu wraz z ciepfem powstalem przy przemianie wapna zracego w wodzian wapnia dziala rugujaoo na krzemiany glinu i kwalsu knze- mowego i powioduje to, ze wodzilam wiapnia i krzemiany wstepuja w zwiajzek chemicz¬ ny, co wlasnie jest niadzwyozialj pozadane przy tworzeniu sile zaprawy.Podi wzgledem ekonomiczinosci1 sposób niniejiszy posiiadto wliiele istotnych korzysci, a mianiowifcie: spalanie wapna w (Specjal¬ nym piecu przy stosowaniu wegla, drzewa lub koksu odpada. Przez wymgówanile i zuzytkowanie wchodzacych w sklaid gruzu gipsowego krzemianów glinu i krzemionki, tworzy sie produkt, który w polaczeniu z portlandcementem nadzwyczaj jest podob¬ ny do tego ostatnfego i wlasciwosci ma pra¬ wie równoznaczne.

Gdy db tego wapna do¬ dac zuzli gipsowych i np, zemlec ralzem, to otrzyma sile doskonala sucha zaprawe do modelowaniiaj, która jest* niemal równo¬ znaczna z cementem portlandzkim, gdyz jak pokazuje doswiadczenie polaczenie o- trzymanego ostatecznego produktu jest równie dobre jak polaczenie z portllandce- menrtern.Gazy powstajace ptfzy spalaniu sie wafp- na|, zawierajacegjo kwas weglowy, moga byc dalej zuzytkowane w sposób dowolny; z powodu swej wielkiej zaiwartoscil kwasu wleglowego w szczególnosci nadaja sile do utrwalania kamieni i cegiel Wszelkich ro- diztail PLThe basis of the method of producing maisy for carving models, which is the forerunner of the invention, is the fact that the aluminum and silicic acid silicates present in the gjps rubble are the most powerful force for preparation of the season without adding a binder. According to the present invention, first of all, before or during combustion in an ordinary furnace, ground viola, containing carbonic acid, talc is accumulated with gilps debris, so that when the debris is burned with heat for a long time, carbon sour is released from lime-containing lime. and it generates the heat of the zest, so ctzais extinguishes the forces that arise from this mixture badly with the help of water or steam, which causes the lime to disappear into calcium hydrate. The heat remaining in the slag together with the heat formed during the conversion of the roughened lime into calcium hydrate acts rugujaoo on the silicates of aluminum and knizemic acid and causes that the limescale and silicates are absorbed into the chemical compound, which is in fact unfavorable for the formation of the mortar. In terms of economy, this method has many important advantages, namely: burning lime in a (special furnace when using coal, wood or coke is eliminated. Due to the necessity and use of the aluminum silicates and silicates contained in the gypsum debris, which form the product, in combination with portland cement it is remarkably similar to the last one and its properties are almost equivalent. Bad gypsum debris consists of more than 13% glucose, 14% iron oxide, 2% potassium, 58% silicic acid, 1 % snarczami acid and 12% wiapmal, when the ceaitent is composed of chambers with 58% lime, 1.3% bitter salts, 9.2% algae, 5% iron oxide, 1% potassium, 1% sodium, 24% silicic acid, 2% carbonic acid and 0.5% salaric acid. The properties of gypsum debris and cement are almost the same, only the cement is not abundantly contained in the cement. z1 walpnem containing carbonic acid, which, when burned, turns into & nourish, nai- ^ | 1ier tfcgo \ missing compound; Then, the easily reacting silicates of alumina and silica, due to the slack and quenching behavior, transform in conjunction with the liquid into a co-reacting principle, thus ensuring durability and consistency of the dry mortar thus obtained. Another embodiment of this method is also, the combustion gases of the debris combustion furnace, gjip oiMBgo, are deposited into a special chamber connected to the furnace, which is half filled with waxnein containing carbonic acid; As a result of the above, the exhaust gases, which, in the course of the experiment, leave the combustion chamber at 800-1000 °, together with the continuous action to drive the carbonic acid out of the calcium it contains, transforming it into a calcified lime. When the lime is added to the gypsum slurry and, for example, grinded with rime, it will get a strength of an excellent dry modeling mortar, which is almost equivalent to Portland cement, because the experience shows that the joint of the final product obtained is as good as the joint. from portllandce- menrtern. The gases produced by the combustion of wafer | containing carbonic acid can be further used freely; due to their high content of fatty acid, they are especially strong for fixing stones and bricks of all kinds PL
