Method for producing artificial cavity stone and twistable cavity stone

Abstract

The invention relates to a method for producing artificial hole stones and twisted-placenta hole stones. The method comprises the following steps: pulverizing 25% of feldspar, 20-30% of quartz, 40-55% of clay and pigments of different colors, milling, mixing thoroughly to form pasty materials of different colors and single color, processing organic substances to granules of different particle sizes, twisting the individual pasty materials of different colors or pasty material of single color with organic granules to obtain blanks, heating the blanks in a drying kiln at gradually-increasing temperature, transferring to a burning kiln and slowly heating up to 1150-1200 DEG C within 7-9 hours, rapidly cooling down to 700 DEG C, cooling naturally, and taking out to obtain the final product. With the production method, the hole stone has solution cavities, from the surface to the interior, similar to the natural hole stone; the physical and chemical properties of the hole stone reach the level of natural hole stone. The twisted-placenta hole stone made by twisted-placenta technique has twisted-placenta patterns from the surface to the interior and vivid effect of solution cavity. The artificial hole stone and the twisted-placenta hole stone can be used as high-grade building material or antique are craft.

Description

Technical field: [0001] The invention relates to the field of materials, in particular to a production method of an artificial travertine that can be used as a building material, a decoration material, and a handicraft material, and a method for producing a twisted travertine in combination with a twisted tire process. Background technique: [0002] Travertine is named for the many holes inside and outside the stone. The scientific name of the stone is tuff or travertine. Commercially, it is classified as marble. Human beings have used this stone for a long time, and the building that best represents Roman culture - the Colosseum is the masterpiece of Dongshiyuan. The tones of travertine make people feel mild, the texture is rich, and the stripes are clear, which makes the decorated buildings have a strong cultural and historical charm, and is used by many buildings in the world. Because of the holes, travertine has low unit density, light weight, and has the function of so...

AI Technical Summary

Problems solved by technology

This method of making artificial travertine is currently more popular. Its disadvantage is that the holes are obtained by compression molding, which can only be distributed on the surface of the stone, and cannot go deep into the inner layer of the material, let alone obtain the karst caves of natural travertine from the surface to the inside.

In addition, due to the production process and raw materials of the existing artificial travertine, the manufactured artificial travertine is easy to weather and fade
