Rise knowledge high temperature porcelain is where sacred war3.replays.net

Rise knowledge "high temperature porcelain" is where sacred? ? high temperature porcelain refers to 1200 degrees above the firing of porcelain. Because of the higher temperature glaze crystal density is bigger, porcelain surface, high strength, not easy to scratch, the color "white" in white and not yellow, "white jade" reputation. Compared with low temperature porcelain, the difference between the two is as follows:, temperature: high temperature porcelain firing temperature of more than 1200 degrees; medium temperature porcelain firing temperature in 1000-1150 degrees; low temperature porcelain firing temperature in 700-900 degrees. 2, color: high temperature porcelain color more full, delicate, crystal; low temperature porcelain is the color of wood lag. 3, handle: high temperature porcelain smooth, delicate, medium and low temperature porcelain slightly rough. ? 4, sound: high temperature porcelain relatively clear; low temperature porcelain is relatively low. 5, texture: high hardness of the high temperature porcelain; low temperature porcelain more fragile. 6, water absorption: high temperature ceramic and low temperature porcelain is the most obvious difference between water absorption rate. High water absorption rate of water absorption in low temperature ceramics, high temperature ceramics rate of less than 0.2%, easy to clean products will not absorb the smell, not glaze cracking and local Water Leakage phenomenon. Water medium and low temperature ceramic rate is much higher than the standard and easily into the sewage, smell is not easy to clean will stink, a long time will crack and Water Leakage phenomenon. (porcelain)?? low temperature porcelain altar if the long time does not carry items, porcelain itself dry brittle, save to the attention of the time, the best thing is to put some grease moisture. But the high temperature porcelain is fired by more than 1300 degrees, the higher the temperature is, the higher the crystal density of the glaze is, the higher the strength of the porcelain surface is, and the more difficult it will be to produce scratches. High temperature porcelain can also be high temperature firing processing, but can not withstand high temperature porcelain firing. Listen to the sound can be a simple distinction, the time of beating, the degree of high temperature porcelain, sound clear, low temperature porcelain is relatively low. But it is still to see the size of water absorption, high temperature sintering of ceramic water absorption is small. High temperature porcelain requires more strict production process, the ordinary kiln mouth is difficult to maintain a stable temperature of the fixed temperature. From the texture analysis, the hardness of high temperature porcelain is more solid, low temperature porcelain more fragile. From the color point of view, high temperature porcelain color more full, delicate, bright, cold porcelain color is relatively simple, more solid. Enough high temperature can make the material fully porcelain, porcelain in high temperature so the density strength, wear resistance and glaze have better performance.相关的主题文章:

Beijing city deputy center will promote the ultra low energy consumption building large-scale develo www.zhaokao.net

Beijing city deputy center will promote the ultra low energy consumption building large-scale development – Politics – people.com.cn original title: cold air in Beijing city center will promote the development of the house construction scale of ultra low power does not come into the house, warm air child out not to go, without air conditioning can achieve constant temperature heating in winter. The day before, the Standing Committee of the municipal government of Beijing city’s "13th Five-Year" period of civil building energy development plan ", the next 5 years, the city will promote the building energy efficiency demonstration pilot, especially the green ecological demonstration area has the conditions in the Beijing City sub center to promote the ultra low energy consumption building large-scale development, energy saving rate increase from 75% to 90%. Ultra low energy buildings not less than 300 thousand square meters by the end of this year, 3 public rental housing in the coking plant will start construction in the ultra low energy consumption building mode, this is the first step to Beijing residential area of low energy consumption building step. At present, the city’s residential energy efficiency rate reached 75%, and the ultra low energy consumption of these public rental housing will be more than 90% energy efficiency, energy saving effect of the first class in the world. "Development plan" shows that the next 5 years, the city will carry out not less than 300 thousand square meters of ultra low energy consumption building demonstration, the government investment projects in the construction of not less than 200 thousand square meters of ultra low energy demonstration projects, green ecological demonstration area has the conditions in Beijing City sub center to promote the development of ultra low energy consumption building scale. The city in the "13th Five-Year" period, will also establish the ultra low energy consumption building technology and standard system, the formation route of building energy efficiency technology in line with the Beijing climate characteristics, building features, construction characteristics and living habits; and cultivate the ultra low energy consumption building industry chain, to provide timely introduction of technical reserves mandatory promotion policy. In addition, affordable housing and government investment in civil construction will be all the use of assembly type construction, the implementation of the structure of the decoration of the finished products. According to the plan, by 2020, the city will achieve more than 30% of the construction of prefabricated buildings. Urban civil construction "green" ratio to exceed 25% according to the development plan, the city will also enhance the proportion of high star green building. Specifically, two star and above the standard full implementation of the new government investment in public buildings and large public buildings; green building demonstration area, key industry functional areas of the new civil construction, in accordance with the green building two star and above standard construction proportion of the construction area of more than 40%; the city center of Beijing municipal administrative office area the construction of green building two star above the level of the three-star green building ratio reached 70%; to encourage the implementation of green building two star and above standard in social capital of real estate development project. In fact, the city is currently required to build a minimum standard of civil buildings is a star green building." City housing and Urban Construction Committee of the relevant responsible person said, the administrative office of Beijing City sub center star level so high, also reflects the green building in the land, water conservation, environmental protection and other aspects of a higher level "". It is understood that by the end of 2020, the city’s green building area of the proportion of the total area of urban civil construction will reach more than 25%, the proportion of green building materials in the new building applications相关的主题文章:
