Definitions
- the invention relates to the field of new materials, in particular to a glass composite material.
- Glass material 1 In the production process of glass, especially in the molding process after melting, homogenization and clarification above 1500 °C, a small amount of alumina crystals, zirconia crystals or silica crystals are melted due to high temperature, so that the The glass loses the properties of high hardness and high wear resistance of each crystal, which eventually leads to low hardness, poor wear resistance and low softening point (below 850 °C) of the glass material; 2 it is impossible to pass the melting and homogenization above 1500 °C , The clarified molding process produces glass-ceramic products with alumina crystals or zirconia crystals or silicon carbide crystals with a content of 20-90%, high hardness and high wear resistance, and it is even more impossible to produce alumina crystals or oxides.
- the glass-ceramic product content of zirconium crystal or silicon carbide crystal is 20-90%, glass composite material with high hardness and high wear resistance properties.
- Ceramic materials The thermal conductivity of ceramic materials is high, reaching 25-80w/[(m.K)], and the thermal insulation performance is poor.
- Metal materials The thermal expansion rate of metal materials at 350-450°C is above 10 ( ⁇ 10-6/°C), and when it is higher than 350-450°C, the thermal expansion will increase exponentially, so it can only withstand instantaneous high temperatures, let alone Long-term exposure to higher temperatures, higher temperatures will cause large deformation of metal materials.
- Natural mineral materials Natural mineral materials have low wear resistance, many cracks in agglomerated ore, and poor strength. Only when crushed into powder (small particles), there will be no cracks and the inherent strength of natural mineral materials.
- Glass-ceramic material Glass-ceramic is crystallization and heat treatment under a certain temperature system, and a large number of tiny crystals are uniformly precipitated in the glass to form a dense multi-phase complex of crystallite and glass phase.
- the crystal is pure crystal, and the glass-ceramic material has the following defects: 1
- the content of alumina in the glass-ceramic phase of the glass-ceramic is very low, so the strength of the glass-ceramic material is very poor, and the glass phase cannot grow with high wear resistance.
- High alumina-containing crystals such as total crystals of mullite and magnesia-aluminum spinel; 2 microcrystalline grains generated by nucleation and crystal growth, such as wollastonite, hectorite, hectorite, gamolite Stone, calcite feldspar, nepheline, etc. These microcrystalline grains have low hardness and low wear resistance, resulting in low hardness and low wear resistance of glass-ceramic materials; 3 The production process of glass-ceramic cannot be stored in the glass memory.
- inorganic non-metallic materials made of natural or synthetic compounds by shaping and high temperature sintering, including silicon nitride or alumina or ceramic nuclei such as silicon oxide or zirconia, so it is even less likely to be obtained from glass-ceramic
- silicon nitride ceramic crystals or alumina ceramic crystals or silicon oxide ceramic crystals or zirconia ceramic crystals are generated, and the proportion of ceramic crystals such as silicon nitride or alumina or silicon oxide or zirconia cannot be controlled according to the application scenario;
- the glass-ceramic material does not have the hardness and wear resistance of silicon nitride or aluminum oxide or zirconia or silicon carbide; The nature of long-term work under working temperature conditions; 6
- the current production process of glass-ceramic materials has low production efficiency and high energy consumption, and can only produce flat-shaped products, but cannot produce products with extremely complex shapes, such as: engines of cylinder liners and cylinder blocks.
- Ceramic materials have the advantages of high hardness, high wear resistance, and can work under high temperature conditions for a long time. According to the advantages of ceramic materials, people also think of using ceramic materials to replace metal materials, such as: Europe, Japan, and the United States have studied and For cars that have produced ceramic engine blocks, in 1990, Shanghai's first water-cooled silicon nitride ceramic engine came out, and the gas inlet temperature could reach 1200 °C.
- the fuel consumption efficiency is 213.56g/km.h, which is far lower than the current 380g/km.h of the 1.5L direct injection engine, which is reduced by 80%. 38%, an increase of 32%, making the thermal energy utilization rate of the ceramic engine reach 70%.
- the fundamental problem of the ceramic engine block is that the functional ceramic material cannot be produced by the casting process of cast iron (after melting) or the die-casting process of aluminum alloy.
- Functional ceramic materials are unable to produce special-shaped, complex-shaped products, including engine blocks.
- the molding temperature of functional ceramic materials is about 1700 °C.
- the isostatic pressing process of special-shaped and complex-shaped products cannot make the ceramic powder in each position of the special-shaped and complex-shaped products equal to the pressure. Therefore, the deformation of products with uneven density is also very large. For example, it is not easy to produce dozens of engine blocks by using functional ceramic materials. It is impossible to achieve industrialized large-scale and standardized production of special-shaped and complex-shaped products.
- the engine cylinder block and cylinder liner are both made of metal materials.
- the performance defects of high-strength alloy steel metal materials or cast iron materials are: 1
- the thermal expansion rate at 350-450°C is above 10 ( ⁇ 10-6/°C), and when it is higher than 350-450°C, the thermal expansion will double. Therefore, it can only withstand instantaneous high temperature, and can not withstand high temperature of 800-1100 °C for a long time, otherwise the cylinder liner will be greatly deformed and the engine will be damaged;
- the traditional engine cylinder block and cylinder liner must be lower than the limit deformation point of cast iron 350-450 °C , a high-speed coolant circulation system must be used to keep the working temperature of the engine cylinder block and cylinder liner below 100-250 °C.
- thermo conductivity of the metal material is above 40-120w/[(mK)], the heat waste, so the utilization rate of heat energy can only be 30%-40%; 3 high-strength alloy steel metal materials or cast iron materials are not good in hardness and wear resistance, in terms of chemical resistance to corrosion and resistance to changes in cold and heat temperature differences, Also worse than ceramic materials.
- the exhaust has heat energy loss, the heat energy is mainly dissipated through the metal cylinder wall of the engine, resulting in a heat engine type piston aircraft engine heat energy utilization rate of only 35%, the waste is too large, and the fuel cannot be fully burned. Affect the environment.
- the existing heat engine turbine engine is the same as the heat engine piston aircraft engine, which requires four stages of intake, pressurization, combustion and exhaust.
- the difference is that in the piston aircraft engine of the heat engine type, the four stages are carried out sequentially in time-sharing, but in the turbine engine of the heat engine type, it is carried out continuously, and the gas flows through each part of the turbine engine in turn, corresponding to four working positions of the piston engine.
- the thermal energy utilization rate of the steam turbine can be greatly improved.
- Traditional insulation materials include aerogel insulation materials, ceramic foam insulation materials and glass foam insulation materials; most of the current aerogel insulation materials are composite materials combining aerogel and reinforcing fibers.
- the defects of the material are: very poor strength, very brittle, and easily broken; the defects of ceramic foam insulation materials are: very poor strength, very brittle, and easily broken; the defects of glass foam insulation materials are: very poor strength, very brittle, Breaks easily.
- the present invention proposes a glass composite material.
- the present invention provides a glass composite material
- the glass composite material includes glass powder particles and filler particles
