Pierwszenstwo: 07.10.1972 (P. 158151) Zgloszenie ogloszono: 01.06.1973 Opis patentowy opublikowano: 19.05.1975 78476 KI. 80b,6/09 MKP C04b 13/14 Twórca wynalazku: Henryk Warachim Uprawniony z patentu tym czasowego: Po I i technika Gdanska, Gdansk (Polska) Sposób wytwarzania gipsu komórkowego Przedmiotem wynalazku jest sposób wytwarzania gipsu komórkowego." Dotychczas znane tworzywa podobne, wystepujace pod nazwami gazogipsu, pianogipsu lub gipsu mikropo- rowatego, otrzymuje sie sposobami polegajacymi na spienianiu zaczynu gipsowego róznymi gazami, powstajacymi i wydzielajacymi sie w reakcjach chemicznych pod wplywem takich dodatków, jak np. kwasny weglan sodowy, mielony dolomit i kwas siarkowy, pyly metali i kwas siarkowy, glina wapn i sta j kwas siarkowy, glina wapnista i siarczan glinowy i innych.Niedogodnoscia opisanych wyzej sposobów jest ich duzy koszt ze wzgledu na stosowanie na ogól drogich dodatków, powodujacych korozje oprzyrzadowania produkcyjnego, slaba wytrzymalosc koncowego produktu, a tym samym ograniczone jego zastosowanie oraz skomplikowany technologicznie proces wytwarzania.Celem wynalazku jest opracowanie sposobu wytwarzania gipsu komórkowego, nie posiadajacego opisanych wyzej niedogodnosci.Cel ten zostal osiagniety przez wprowadzenie do zaczynu gipsowego, przy intensywnym mieszaniu, dwu¬ tlenku wegla pod cisnieniem do 5 atm, a nastepnie przez wylanie tego zaczynu do form, w których nastepuje proces spieniania zaczynu z jednoczesnym procesem wiazania gipsu.Zaleta sposobu wedlug wynalazku jest prosta i tania technologia wytwarzania gipsu komórkowego, mozli¬ wosc regulacji wielkosci porów, znaczne zmniejszenie korozji oprzyrzadowania produkcyjnego oraz róznorod¬ nosc zastosowania wytworzonego proponowanym sposobem produktu, np. jako materialu izolacyjnego, dzwiekochlonnego, budowlanego itp.Sposób wytwarzania gipsu komórkowego wedlug wynalazku ilustruje po i nizszy przyklad.P r z y k l a d.Do 800 g wody dodaje sie przy ciaglym mieszaniu 1000 g ni psu budowlanego. Po 3 minutach otrzymany zaczyn gipsowy przy intensywnym mieszaniu nasyca sie dwutlenkiem wegla pod cisnieniem 2,5 atm i po uplywie 12 minut wylewa sie go do do formy, w której zachodzi proces spieniania zaczynu gipsowego wskutek gwaltownego wydzielania sie pecherzyków dwutlenku wegla z równoczesnym procesem wiazania gipsu.2 78 476 PL PLPriority: October 7, 1972 (P. 158151) Application announced: June 1, 1973 Patent description was published: May 19, 1975 78476 KI. 80b, 6/09 MKP C04b 13/14 Inventor: Henryk Warachim Entitled to the temporary patent: Po I i Technique Gdanska, Gdansk (Poland) Method for the production of cellular gypsum. The subject of the invention is a method for the production of cellular gypsum. "Previously known similar materials occurring under the names of gas gypsum, foam gypsum or microporous gypsum, are obtained by methods of foaming gypsum slurry with various gases, produced and released in chemical reactions under the influence of such additives, e.g. acid sodium carbonate, ground dolomite and sulfuric acid, metal dust sulfuric acid, clay, lime and sulfuric acid, calcareous clay and aluminum sulphate, etc. The inconvenience of the above-described methods is their high cost due to the use of generally expensive additives, causing corrosion of production equipment, poor strength of the final product, and thus limited its use and the technologically complex manufacturing process The aim is to develop a method for the production of cellular gypsum without the above-described disadvantages. This goal was achieved by introducing carbon dioxide into the gypsum slurry under a pressure of up to 5 atm, and then pouring it into the molds in which it is carried out. the process of foaming the slurry with the simultaneous gypsum binding process. The advantage of the method according to the invention is the simple and cheap technology of cellular gypsum production, the possibility of regulating the size of the pores, a significant reduction in the corrosion of the production equipment and the variety of applications of the product produced by the proposed method, e.g. as an insulation material, The method of producing cellular gypsum according to the invention is illustrated by the following example and the following example: Example d. Up to 800 g of water are added, with continuous stirring, 1000 g per building dog. After 3 minutes, the obtained gypsum slurry is saturated with carbon dioxide under a pressure of 2.5 atm under intensive stirring and after 12 minutes it is poured into the mold, where the gypsum slurry foaming process takes place due to the rapid release of carbon dioxide bubbles with the simultaneous process of gypsum binding .2 78 476 PL PL
