无机非金属概论重点（Introduction to inorganic nonmetal） 1 inorganic non-metallic materials: oxygen of some element of O C carbide nitride N CL boride B and halogen compound silicate, aluminate and borate phosphate. Chemical composition of materials, besides organic polymer materials and metal materials of all materials collectively. 2 inorganic non-metallic material characteristics: high temperature resistance, high chemical stability, high strength, high hardness, good electrical insulation, poor toughness 3 general characteristics of inorganic non-metallic material production process: preparation and transportation of raw material powder, high temperature heating (heat treatment), molding and drying 4, inorganic non-metallic materials production process personality: cement PHPF or PHP glass, PHF ceramic, PFH, P powder, H heat treatment, F molding 5 cement production: dry raw material after drying and crushing raw material powder is then fed into the kiln clinker calcination method of semi dry raw powder by adding an appropriate amount of water will be made of raw meal ball feeding or Lepol kiln and kiln calcined into clinker raw materials and methods of wet grinding of raw slurry to feed water clinker calcination method rotary kiln 6 kinds of raw materials: calcium, clay, quartz, feldspar, other (high alumina, magnesia, iron, NA2O, boron, auxiliary raw materials) Properties of 7 clay plasticity clay and water mixing after the formation of the mud under the action of external force caused by a variety of shapes and plasticity not crack when the external force disappears, can still maintain the shape invariant properties of the ion exchange of thixotropic mud and clay or plastic mud pie in static after thickening or solidification when subjected to stirring or vibration when the viscosity and liquidity increased again after a period of time to restore the original state of expanded clay water body product expansion properties of shrinkage drying shrinkage + firing shrinkage p
