DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figures 1 to 3 A magnesium-based zirconia fiber refractory felt with strong heat insulation in this embodiment includes a refractory felt body 1, and a heat insulation effect enhancing mechanism is arranged on the refractory felt body 1.
[0021] See also Figure 1 , Figure 2 and Figure 3 The heat insulation effect enhancing mechanism includes an adhesive surface 2 located at the bottom of the refractory felt body 1, and a buffer layer 3 is arranged on the top of the adhesive surface 2. The buffer layer 3 is made of silicone rubber. The buffer layer 3 is uniformly adhered to the top of the adhesive surface 2, and the buffer layer 3 made of silicone rubber is convenient to improve the use strength of the contact part of the refractory felt body 1 with the object during use through the high temperature resistance, corrosion resistance, good mechanical strength and good waterproof performance of silicone rubber.
[0022] Among them, a resin layer 4 is arranged on the top of the buffer layer 3, and the resin layer 4 is a polyetheretherketone resin. The resin layer 4 is a polyetheretherketone resin dissolved in an appropriate solvent and coated on the top of the buffer layer 3 by spraying, so as to conveniently utilize the wear resistance, high temperature resistance and corrosion resistance of the polyetheretherketone resin to improve the service strength of the refractory felt body 1 and improve its heat resistance. A metal mesh 5 is arranged on the top of the resin layer 4, and the metal mesh 5 is laminated and interlaced with the internal materials of the refractory felt body 1. The metal mesh 5 is combined with the internal materials of the refractory felt body 1 to improve the strength and stability of the metal mesh 5 as well as the thermal insulation and fire resistance of the refractory felt. When stacking, the metal mesh 5 and the refractory felt can be firmly bonded by adhesives, welding or other mechanical connection methods.
[0023] Among them, a transverse reinforcement rib 6 is fixedly installed on the top of the metal mesh 5, and a metal wire 7 is laid on the top of the transverse reinforcement rib 6. The number of metal wires 7 is multiple, and the multiple metal wires 7 are staggered with each other, so that the bearing force of the refractory felt body 1 during use can be evenly distributed through the multiple metal wires 7, thereby enhancing the overall structural strength and stability. A glass fiber layer 8 is arranged on the top of the metal wire 7, and a ceramic fiber layer 9 is arranged on the top of the glass fiber layer 8. Vertical reinforcement ribs 10 penetrate the interior of the refractory felt body 1. The transverse reinforcement ribs 6 and the vertical reinforcement ribs 10 are both made of carbon fiber, and the transverse reinforcement ribs 6 and the vertical reinforcement ribs 10 are vertically distributed, so that the strength of the refractory felt body 1 can be improved through the transverse reinforcement ribs 6 and the vertical reinforcement ribs 10 made of carbon fiber, and its internal structures can be supported to improve its use effect.
[0024] Among them, the outer side of the refractory felt body 1 is coated with a magnesium zirconia fiber layer 11. A dense heat insulation layer is formed on the surface of the magnesium zirconia fiber, effectively improving the heat insulation performance of the refractory felt. At the same time, this heat insulation layer has good high-temperature stability and corrosion resistance, and can ensure the stable use of the refractory felt in a long-term high-temperature environment.
[0025] It should be noted that for this magnesium zirconia fiber refractory felt with enhanced heat insulation, through the provided heat insulation enhancement mechanism, under the interaction between various structures inside the refractory felt body 1, the refractory performance and mechanical strength of the refractory felt body 1 during use are effectively improved by the magnesium zirconia fiber layer 11, and the heat conduction rate of the refractory felt body 1 is effectively reduced through the buffer layer 3, resin layer 4, metal mesh 5, metal wire 7, glass fiber layer 8, and ceramic fiber layer 9 inside it, thereby further enhancing its heat insulation performance.
[0026] The working principle of the above embodiment is as follows:
[0027] For this magnesium zirconia fiber refractory felt with enhanced heat insulation, during the production of the refractory felt, the buffer layer 3, resin layer 4, metal mesh 5, transverse reinforcing rib 6, metal wire 7, glass fiber layer 8, ceramic fiber layer 9, vertical reinforcing rib 10, and magnesium zirconia fiber layer 11 are combined in sequence. Through the production equipment, the above structures are distributed, paved, and compressed. Finally, the magnesium zirconia fiber layer 11 is evenly coated on the outer side of the refractory felt body 1. Using magnesium zirconia fiber as the main raw material, the refractory felt has excellent refractory performance and mechanical strength. A dense heat insulation layer is formed on the surface of the magnesium zirconia fiber, effectively improving the heat insulation performance of the refractory felt. At the same time, this heat insulation layer has good high-temperature stability and corrosion resistance, and can ensure the stable use of the refractory felt in a long-term high-temperature environment.
