Glaze dewaxing casting

<p>Prototype sculpture first design the shape of the glass works, according to the design sculpture prototype (male model) The silicone mold is coated with silicone on the prototype. Production of silicone mold (female mold) wax mold In the silicone mold into the liquid wax, wax solidified after the wax mold. The wax pattern is removed from the silicone mold and  prices plastic deck boards  the details are trimmed. Pour the gypsum mold in the wax mold outside the cast gypsum, the production of gypsum mold (female mold). </p><p>Steam dewaxing Wax the wax in the mold with high temperature steam to ensure that there is no residual wax in the gypsum mold. Firing casting will be frit, and gypsum mold into the high-temperature furnace, until the glass frit melted, poured into the plaster mold. And then let the kiln temperature is slow, uniform decline, so that the glass in the gypsum mold fully solidified into rough, if the kiln temperature drop too fast or uneven, easy to cause the glass in the  outdoor wood floor tile  solidification process due to thermal expansion and contraction of the broken.</p><p> Demoulding the gypsum mold to separate the gypsum mold from the glass blanks, and after polishing the blanks, the rough surface is polished and the glossy of the glass works is ensured. The construction of the glass and the production of the glazed tiles  The main component of the glass tires is clay, its composition is silica, alumina  using platic to make door panels  and a small amount of iron oxide, calcium oxide, manganese.</p><p> After 1100 degrees above the high temperature fired after the glaze, and then 800 degrees to 900 degrees of low temperature firing. Liubian tire material to Anhui Tuoba clay production of clay the best quality, after firing was white. Glazed glaze is divided into three parts, namely oxidants, colorants and quartz. Oxidants are yellow (lead oxide) and nitrite (potassium nitrate). Colorants include iron oxide, copper oxide, cobalt oxide, manganese dioxide and other metal oxides, according to a variety of  100 % plastic deck Catalonia  different colorants with the proportion of modulation of yellow, blue, green, white, peacock blue, eggplant purple and other colors.</p>
