Clay tile origin!

Aoxiang Continental watt mainly made into wet clay and shale embryos dried by high temperature after firing. At elevated temperatures over 1000 degrees, curing clay pottery, after more than 1,200 degrees basically porcelain, and generally terracotta temperature at below 1200 degrees. Aoxiang tile is 82 meters by precision thermostat temperature tunnel kiln firing from 1200 degrees. Chinese ancient early Western Zhou have to use clay tile records, the Tang Dynasty in the vast southern region after extensive use of glazed tiles on the roof as an important decorative materials. While glazed tile is baked clay, but it is not clay tile in the usual sense to us. Clay tile is thousands of years of Chinese culture, excellent headed roofing products, stable atmosphere. Shale is tiny particles of clay formed by the hardening substance easily break, and it is easy to split into distinct rock formations. A clay rock. Complicated, in addition to clay minerals (kaolinite, montmorillonite, water mica, thanks to stone, etc.), but also contains a lot of detrital minerals (such as quartz, feldspar, mica, etc.) and authigenic minerals (such as iron, aluminum manganese oxides and hydroxides, etc.). A sheet-like or flaky bedding. With a hard object hitting breakable pieces. It is a clay material by compaction, dehydration, after recrystallization form. By the very fine clay, shale, squeezing through consolidation, dehydration, after recrystallization formed a thin sheet-like structure of clay rock bedding, known as shale. (Foliation is scaly clay mineral in the pressing process, the parallel arrangement of the) shale dense, dull gloss surface. Containing organic matter was dark gray, black. Shale iron brownish red, reddish brown and other colors, as well as yellow, green and other colors. Impermeable shale, often become impermeable layer or impermeable layer. Shale its silicon, calcium, carbon content is divided into different siliceous shale, calcareous shale and carbonaceous shales. Among siliceous shale deformation, moisture absorption, easy to weathering and product quality assurance, and other advantages will be more easily adapted to the production of shale tile use. Shale and clay have similar chemical composition, silicon, calcium, aluminum, iron compound more than 80% of the total composition. Sintered shale tile market has great potential in our country is a worthwhile promotion of new wall materials. Ceramic tile insulation resistance, low thermal conductivity, heat loss, the thermal conductivity of shale tile body is 0.81w / mk, thermal insulation effect, can effectively change the summer and cold winter conditions. Meanwhile impermeability, fire resistance, these advantages make ceramic tiles much favored by the construction industry. With the accelerated pace of villages and rural tile rate increase, the rural demand for energy efficient building material and increasing demand especially in the Northeast, Northwest and other cold regions more urgent. In line with the policy, to adapt to the development requirements of the construction industry with the development of the social economy, the construction industry has been the rapid development, development of new building materials products in the expanding shale. In 2005 the State Council issued the SCS [2005] No. 33 "on the further development of better wall materials innovation and promotion of energy-saving buildings," which actively called new building materials, products, development and promotion of the use. Economic and social development in China, "Nine Five" plan and 2010 vision also clearly outline the revitalization pillar industries, the development of building materials industry and construction To build urban and rural housing and public facilities, focusing on the development and promotion of new building materials and products. National Building Materials Bureau identified in Beijing, Tianjin, Harbin and other 20 cities for the development of new building materials and products of the pilot cities, to cold and cold areas of the city to meet all the new residential energy efficiency design standards.
