Ceramic matrix composites can be divided into two categories according to the continuity of the reinforcement: continuously reinforced composites and discontinuously reinforced compositesthrough the optimization of the preparation process, especially the composition and structure design of the interface layer, the mechanical properties of ceramic matrix composites have been qualitatively improved compared with single-phase ceramicscomparison of preparation processes of ceramic matrix composites
chemical vapor infiltration (cvi)
during the preparation process, the fiber damage is small, the prepared ceramic matrix has high purity and complete crystal form, and the mechanical properties of the composite material are high
high temperature resistancecom/news/ceramic-matrix-composite-cmc-material-professional-manufacturer-in-chinain general, it is carried out in conjunction with other methodsunder the condition of no cooling structure, it can be used for a long time at 1200°ccmc material introduction
ceramic matrix composites (cmc) are a type of composite material that is composited with ceramics as a matrix and various fibersoverview of ceramic matrix composites——advantages
lightweight
high stability
continuous fiber-reinforced ceramic matrix composites are the most outstanding type of materials in ceramic matrix

composites
excellent mechanical propertiesit is a high-performance composite material formed by implanting high-temperature-resistant continuous ceramic fibers into a ceramic matrixthe ceramic matrix composite material has a low density (only 1/3~1/4 of the superalloy), and can be used in components such as combustion chambers, regulating plates/sealing plates, and can directly reduce the mass by about 50%continuous fiber reinforced ceramic matrix composites have been widely used in aerospace, national defense and other fields
ceramic matrix composites refer to the introduction of reinforcing materials into the ceramic matrix to form a composite
carbon ceramic composite
carbon ceramic composite
material with the introduced reinforcing material as the dispersed phase and the ceramic matrix as the continuous phasewith the advancement of fiber preparation technology and other related technologies, people have gradually developed effective methods for preparing such materials, making the preparation technology of fiber-reinforced ceramic matrix composites increasingly matureceramic matrix composites can greatly improve the reliability and consistency of materials while maintaining the excellent performance of a single ceramic material such as high temperature resistance, high strength, and low density
liquid silicon infiltration (lsi)
first, carbon fiber is woven into a three-dimensional fabric (hereinafter referred to as carbon fiber preform); a layer of simple silicon with a thickness of 01-2 μm is deposited on the carbon fiber preform by vapor deposition technology; phenolic resin, carbon black, ethanol, ultrafine silicon carbide powder, polyvinylpyrrolidone and tetramethylammonium hydroxide are prepared in proportion to make a mixed slurry; the slurry is pressurized and impregnated into the above-mentioned carbon fiber prefabricated body in a vacuum environment to obtain a composite material green body; the above-mentioned green body is heated and solidified; the cured green body is placed in a vacuum furnace for high-temperature siliconization reaction to obtain a high-density, high-performance carbon-silicon carbide ceramic composite materialit has high strength and high toughnessthe working temperature of ceramic matrix composites is as high as 1650°c, which can simplify or even eliminate the cooling structure, optimize the engine structure, and increase the working temperature of the engine
the manufacturing cycle is long, the cost is high, and the prepared composite material has high porositytubes, missile radomes, space shuttle nose cones, aircraft brake discs, and high-end automobile brake discs have become an important branch of the field of composite materialsit has the characteristics of high temperature resistance, wear resistance, high temperature creep resistance, low thermal conductivity, low thermal expansion coefficient, chemical corrosion resistance, high strength, high hardness and wave penetration, and is widely used in many fields such as aerospacein particular, it has a non-catastrophic fracture mode different from that of a single ceramic, which has attracted great attention from researchers all over the worldceramic matrix composites can maintain high stability in high temperature environments, even in aerobic environments, which reduces the development and application costs of thermal protective coatingsIndia

large height and long opening and closing time
the structure length is small
area of application
marine industry, water supply & drainage, fire fighting, shipbuilding, water treatment, power stations, energy, food, chemical, and other systems
data sheet of gate valve:
type: wafer, double flange
size & connections: resilient seated: dn50 to d600
metal seated: dn50 to dn1200
medium: waste water, water, seawater, air, inert gas, oil
gate valves generally have two sealing surfaces, adding some difficulties to processing, grinding and maintenance
disadvantages
the overall dimensions and opening height are largethe movement direction of the gate plate is perpendicular to the direction of the fluidthe reason is the long shutdown timeusually, the sealing surface will be welded with metal materials to increase wear resistance, such as 1cr13, stl6, stainless steel, etcthe gate valve is sealed by the contact of the valve seat and the gate plate
less effort when opening and closingthe gate valve can only be fully opened and fully closed, and cannot be adjusted or throttledthe gate has a rigid gate and an elastic gatethe space required for installation is largeaccording to the different gate plates, the gate valve is divided into a rigid gate valve and an elastic gate valve
during the opening and closing process, there is relative friction between the sealing surfaces, which can easily cause scratches2 cert (on request)
standards
design and manufacture conform to awwa, bs5163, din-f4,f5
dimensions conform to en1092-2,ansi b16
the shape is simple, the structure length is short, the manufacturing process is good, and the application range is wide
