Andalusite Refractory plastic

Andalusite Refractory plastics production in China has not yet developed, nor the corresponding national standards, such as it is here referring to the current standard GB4758 its products for technical performance evaluation. To ensure the development of quality products, important physical and chemical testing and inspection work commissioned outside the domestic refractories testing authority - the Ministry of Metallurgical Industry Engineering Quality Supervision and Testing Center Station is completed.

• Main indicators of the chemical composition of the chemical composition of products for A12O3 (48 10%.)to 510: (42.60%), is a standard A12O3-510: series, the rest of the iron, and other impurities in Chin are not exceeded.
• Physical performance cold compressive strength: 180 ℃ x24h to 13,2 MPa, 1400 ℃ x3h to 31.7MPa; room temperature flexural strength: 180'Cx24h as 9.oMPa, 1400Cx3h to Z.6MPa; refractoriness: 17501770 ℃; bulk density: 2,059 / em,Luoyang plexiglass products high temperature flexural strength, flexural strength after burning room temperature flexural strength were better than the national standard, the performance is excellent, widely used in high temperature, high pressure resistance, thermal shock, high temperature corrosion resistance of various types of furnaces.
• Main characteristics (l) the main raw material for the andalusite , is A1203-510 series neutral refractories , which use temperature range : 1000-1700C. At room temperature viscoplastic strong adhesion large , especially for wall pipe location and structure complex and difficult construction sites and various other parts of the door opening .(2)can be naturally dry, construction site without any special maintenance; high consolidation strength after drying , shock resistance, resistance to cracking and swap blocks.(3)improve the use of parts of the structure and improve the furnace sealing performance , energy-saving effect is remarkable.(4)show strong thermal stability ,
  
  much better than traditional refractory concrete and other fire-resistant plastic .(5)high cost performance. Although the price is higher than the conventional refractory, but the technical indicators and all kinds of life is far greater than traditional materials , and the price of similar imported less than 1/ 2 of the product .(6)stable quality products for storage , transportation. In the cold north , the product is placed . 'C following storage , although the cold hard, but eliminate cold performance unchanged.(7)non-toxic, tasteless , non-corrosive , no pollution, no burning, no damage to the health of construction workers , are very safe to use and safekeeping .(8)at the construction site without the ingredients , mixing , formwork and water operations , the products can be used to open the package , you can improve working conditions, improve efficiency, shorten the construction period . The remaining material , as long as you can continue to use sealed , no waste .
