Description
Vynález sa týká sposobu nanášania glazur na keramické materiály v elektrickom poli, rieši problém zhospodárnenía technologického- procesu glazúrovania, využitím schopnosti elektrického pol'a orientovat nabité častíce glazury na povrch výrobku.The invention relates to a method of applying glazes to ceramic materials in an electric field, solving the problem of economizing and technological glazing process by utilizing the ability of the electric field to direct charged glaze particles to the surface of the article.
Podla súčasného stavu techniky sa povrchová úprava keramických výrobkov robí mokrým spósobom nanesenia glazúry na vypálený výrobok, čo si vyžaduje dvojitý výpal. Tento spSsob je náročný na manipuláciu s materiálem, dvojitý výpal má za následek vysokú spotřebu elektrickei energie a nepriaznivo vplýva na výrobnú kapacitu výrobného závodu. Dvojité vypařovanie podlá doterajšieho stavu techniky je potřebné najmá preto, aby nedochádzalo ku chybám na povrchu výrobkov, ktoré sú výsledkem objemových zmien ílových materiálov, absorbujúcich vlhkost zo- suspenzie nanesenej glazúry mokrým sposobom. Tento problém je v súčasnosti riešený samostatným vypalováním výrobku před glazováním.According to the state of the art, the surface treatment of ceramic products is done in a wet manner by applying the glaze to the fired product, requiring double firing. This method is demanding on material handling, double firing results in high power consumption and adversely affects the production capacity of the production plant. Double evaporation according to the prior art is particularly needed in order to avoid surface defects resulting from volume changes in the clay-absorbing clay materials from the wetted glaze suspension. This problem is currently solved by separately firing the product before glazing.
Tíeto nevýhody odstraňuje sposob nanášania glazúr na keramické materiály v elektrickom poli podlá vynálezu, ktorého podstata spočívá v tom, že sa glazúra nanáša v sůchom stave vo formě upraveného prášku s velkosťou častíc pod 80 ,иш a -s měrným elektrickým odporom váčším ako 1.This disadvantage removes the method of applying glazes to ceramic materials in an electric field according to the invention, which is characterized in that the glaze is applied in a dry state in the form of a treated powder having a particle size below 80, η and having a specific electrical resistance greater than 1.
i . 1010 ohm.m, najlepšie v rozmedzí 1. 1O10 až 1. 1013 ohm . m·i. 10 10 ohm.m, preferably in the range 10 10 to 1 1013 ohm. m ·
Výhodou sposobu podlá vynálezu je, že umožňuje nanášat glazúru na 1'ubovolný keramický materiál, ktorý može byť aj v surovom stave, bez nutnosti vypalenia pod kladového materiálu, při dosiahnutí rovnomernej a bezchybnej vrstvy glazúry aj na materiálech so zložitou geometriou povrchu. Výsledným účinkom novej technologie podlá vynálezu, vyplývajúcim z jednorázového výpalu, je teda zníženie spotřeby energie na jednotku výrobu glazovaných výrobkov až o 50 % a zníženie spotřeby glazúr na jednotku plochy keramických výrobkov viac ako o 50 %.An advantage of the process according to the invention is that it allows the glazing to be applied to any ceramic material, which can also be in the raw state without the need to burn under the of the glazing, even on materials with complicated surface geometry. The resultant effect of the new technology according to the invention resulting from the disposable firing is thus a reduction in energy consumption per glazing unit by up to 50% and a reduction in glaze consumption per unit area of ceramic products by more than 50%.
Sposob podlá vynálezu možno uskutečnit na příklade surověj keramickej škridlice, na ktorú sa elektrostaticky, .při napatí 50 kV, nanáša glazúra v suchom stave vo formě upraveného prášku, ktorého velkost častíc je v rozmedzí spektra od 1 až 63 (um, a ktorého měrný elektrický odpor je 1,6 . . 1011 ohm. m. Prášok je upravený tak, že jeho častíce sú obalené metylhydrogenpolysiloxanom, ktorého hmotnostný podiel voči prášku je 0,1 %, pričom k tomuto- obalovadlu -sa přidá 5 - až 10 % - dibutylcíndilaurátu, resp. naftenátu kobaltnatého. Glazúra sa nanáša v priebežnej podtlakovej kabině pomocou ručných alebo automatických pištolí s příslušným podávačom práškov, vytvárajúcich vhodný aerosol. Kabina je opatřená odsávacím zariadením, ktoré vyúsťuje do· cyklónového odlučovača práškov. Prášok oddělený v odlučovači je opáť dopravovaný do podávača k opakovanému použitiu. Uzavretý cyklus pohybu prášku zabraňuje znečistovaniu pracovného prostredia a stratám na materiále. Výrobky určené k naneseniu glazúr prechádzajú plynule cez priebežnú kabinu na dopravníku, kto rý může byť súčasťou integrovanej medzioperačnej dopravy medzi operáciami tvarovanie a vypaťovanie- Takto nanesená glazúra sa ďalej vypaluje běžným spůsobom při teplotách 800 až 10'00 °C, v závislosti od vlastností použitej glazúry a keramického materiálu. Přitom sa dosahuje velmi kvalitný povrch glazúry.The process according to the invention can be carried out using, for example, a raw ceramic tile to which an electrostatically applied at a voltage of 50 kV is applied in a dry state in the form of a modified powder having a particle size in the spectrum of 1 to 63 ( µm). the resistance is 1.6, 1011 ohm m, the powder is treated such that its particles are coated with methylhydrogen polysiloxane, the proportion by weight of which is 0.1%, and to this coating is added 5-10% of dibutyltin dilaurate The glaze is applied in a continuous vacuum booth using hand or automatic guns with an appropriate powder feeder generating a suitable aerosol.The booth is provided with an exhaust device which results in a cyclone powder separator. closed cycle of powder movement from The glazing products pass continuously through a continuous conveyor cab, which can be part of the integrated in-process transport between shaping and digestion operations. 00 ° C, depending on the properties of the glaze and ceramic material used. This achieves a high-quality glaze surface.
Keramickým materiálom, vhodným pre nanášanie glazúr podlá vynálezu, sú okrem toho aj různé keramické obkladačky, překladové panely apod.The ceramic materials suitable for the application of the glazes according to the invention are also various ceramic tiles, lintel panels and the like.
