Glaze chemical intermediate layer formed between the tires and the glaze composition, the nature of the microstructure of the buffer layer are interposed between the body and glaze.
Glaze Adaptability: glaze layer has a coefficient of expansion with the tire matches, will not come to glaze cracked or peeling performance.
Flexible glaze: The glaze layer ability to resist stress or tensile stress.
Glaze Wettability: spreadability upon melting glaze on the performance of the carcass surface.
Ceramic microstructures: Under the microscope to the type of ceramic phase composition, shape, size, quantity, distribution and orientation; various impurities exist in the form of microscopic defects, distribution; grain boundary character.
Glass: the body or glaze during firing, the glass phase until the product began firing process.
Solid phase reaction: reactant and product contain a solid phase, and the chemical composition of each different reaction.
Flux: to make the material in the lower temperature of the molten material.
Chemical composition: percentage by weight of the various materials contained in the oxide.
Exemplary mineral composition: Chemical composition of the material converted into mineral composition theory.
The experimental formula: chemical formula of various material composition than the number of components. Ceramic materials are usually expressed as the number of moles of various oxides.
Acidity coefficient: the ceramic body and the glaze of formula wherein the number of moles of an acidic oxide and a basic oxide and neutral ratios of oxides mole predetermined formula.
Drying medium: the dryer for moisture evaporation materials thermals.
Working Moisture: blank is best suited to the forming operation of the water.
Drying water balance: Material dried to ambient temperature and humidity were water balance state.
Chemically bound water: participation in the composition of the mineral lattice of water, including the structure of water, crystal water.
Critical Moisture: the process of drying, evaporation of moisture is no longer generated due to contraction of the water.
Internal diffusion: When material drying, moisture migration from the interior to the surface of the process. Out-diffusion: The material was dried, the water evaporates from the surface to the surrounding medium process.
Kiln gas stratification: height along the kiln chamber uneven distribution of gas temperature phenomenon.
Constant drying phases: the diffusion and external diffusion rate equal to the material surface humidity constant drying stage.
Plastic materials: given plasticity and binding materials in the ceramic ingredients.
Barren material: adding water does not have the plasticity of the material.
China Stone: A porcelain stone materials are available, the main mineral component of sericite and quartz, or contain small amounts of feldspar, kaolinite and carbonate minerals.
Stone Glaze: Glaze with porcelain stone, its mineral composition and mined similar, but has a lower melting temperature, melt with good transparency.
Clay: a commonly known as plasticity of soil or powdered ingredients. Mainly used for porcelain.
No child: Jingdezhen ceramics industry slang used in the region. Department of native clay, glaze porcelain stone or crushed stone processing, brick-like ceramic material made after washing.
Shi Tao: one containing impurities, mineral composition is more complex, the main raw material used in pottery soil.
Thinner: to improve or enhance the mud flow and prevent mud flocculation electrolyte.
SC: to prevent glaze, mud generated by precipitation component separation, maintaining good additive suspension and stability.
Emulsifying agent: can be very fine particles suspended in the glaze, so that the light produced diffuse, opaque glaze was a substance.
Base color: coloring agents, and other materials to complex, prepared by calcination of the inorganic coloring material.
Glaze concentration: refers to the glaze dry material weight. Moisture content or specific gravity or Baume generally used to represent the glaze.
Frit: water-soluble materials, toxic materials and other ingredients from melting materials.
Washing: The powdered raw material is stirred in water, use of the difference of gravity, so that the coarse particles and the selection of raw materials and an inclusion method for the separation.
Sieving: The powder passed through the sieve to operate.
Iron: The physical or chemical methods to remove iron glaze raw materials or impurities.
Clay: a vacuum pug mill, or other methods of plastic molding blank for kneading, the blank gas oven to uniform moisture, improve plasticity processes.
Drying system: In order to achieve the best drying results, the various stages of the drying process of drying time and speed, temperature and humidity of the drying medium parameters such regulations.
Male mold: refers Face projections for forming the inner surface of the model.
Die: Face concave means for forming the outer surface of the model artifacts.
Firing system: Qualified for firing ceramic products and achieve the best results firing of the kiln temperature, atmosphere, pressure specified operating parameters.
Oxidizing atmosphere: the kiln gases oxidation ability, its excess air ratio is greater than one, said the kiln atmosphere is oxidizing atmosphere.
Reducing atmosphere: with a reduction gas kiln capacity, the excess air ratio less than 1, said the kiln atmosphere is a reducing atmosphere.
Neutral atmosphere: the kiln gas does not have the ability to oxidation and reduction, which is equal to an excess air ratio, called the kiln atmosphere for neutral atmosphere.
Atmosphere transition temperature: refers to the kiln temperature oxide into the atmosphere when a reducing atmosphere.
Excess air ratio: the ratio of the actual air-fuel combustion with the theoretical amount of air amount.
Firing cycle: the time stipulated in the firing curve when firing is completed.
Glaze: with high temperature capability of certain pigments or decals made by it in the glaze blanks or articles carried polychrome glazed to at or near the same temperature glaze firing temperature sintering, and fused pigment sinking glaze decoration method.
New color: a performance practices varied, colorful, easy-to-overglaze decoration.
Chemical analysis: Determination of ceramic materials or finished in SiO2, A12O3, Fe203, TiO2, CaO, MgO, K2O, Na2O and other content and loss on ignition.
Differential thermal analysis: the sample is heated with an inert material in the process under the same conditions, the temperature difference at any time of the analysis generated by the temperature change occasionally recorded.
Inert Material: When subjected to differential thermal analysis, and the sample is used to compare the effect of the size of the thermal material, which requires a temperature in the range of the measurement without the occurrence of thermal effects.
Plasticity index: liquid limit and plastic limit pug difference.
Plasticity index: clay in water at work, by the product of the stress and strain of the external force when the first crack appeared.
Firing range: porcelain, the porcelain-based chemical conversion by the glass softening temperature to below the temperature range between; pottery, the water absorption of the article is the lower limit of the corresponding temperature range.
Thermal stability: ceramics dramatic changes in the outside temperature crack resistance capacity is not damaged or not appear.
Bulk density: The ratio of the quality and the total volume of 110 drying of ceramic materials.
Water absorption: After opening pores in the ceramic matrix saturated with water, the weight of the water sample dried to constant weight percentage of weight by 110 after inhalation.
Mechanical strength: in the external force, ceramic materials resistant to damage. According to the nature of the external force is applied, the mechanical strength into tensile, flexural, compressive strength and impact strength.
Lead (Cd) dissolution of: ceramics and food contact surfaces by immersion after the release of acidic medium Lead (Cd) amount.
hemihydrate gypsum: Gypsum pressure cooking in the presence of water vapor was obtained by needle crystals, crystal size larger hemihydrate gypsum (a-C aSO41 / 2H2O).
