結(jié)構(gòu)的影響

　　The impact of structure

　　金屬面夾芯板：夾芯板的結(jié)構(gòu)通常由兩層金屬面板和中間的芯材組成。不同的芯材會影響夾芯板的性能。例如，巖棉夾芯板的中間芯材為巖棉，其纖維結(jié)構(gòu)能夠起到隔熱和防火的作用；EPS 夾芯板和聚氨酯夾芯板的芯材為有機泡沫材料，雖然具有良好的保溫性能，但耐火性能較差。當與巖棉組合使用時，夾芯板的結(jié)構(gòu)可以發(fā)揮巖棉的耐火性能和有機泡沫材料的保溫性能，從而提高整體的性能。

　　Metal faced sandwich panel: The structure of a sandwich panel is usually composed of two layers of metal panels and a core material in the middle. Different core materials can affect the performance of sandwich panels. For example, the middle core material of rock wool sandwich panel is rock wool, and its fiber structure can play a role in insulation and fire prevention; The core material of EPS sandwich panel and polyurethane sandwich panel is organic foam material, which has good thermal insulation performance, but poor fire resistance. When used in combination with rock wool, the sandwich panel structure can give play to the fire resistance of rock wool and the thermal insulation performance of organic foam materials, thus improving the overall performance.

　　換流站封堵復(fù)合板：復(fù)合夾芯板的結(jié)構(gòu)通常由多層材料組成，如鋼板、硅酸鋁板和空氣層等。硅酸鋁厚度相等時，背火面溫度隨著空氣層厚度的增大而減小。這表明空氣層的存在可以起到隔熱作用，從而影響復(fù)合夾芯板的耐火性能。

　　Converter station sealing composite panel: The structure of composite sandwich panels is usually composed of multiple layers of materials, such as steel plates, aluminum silicate plates, and air layers. When the thickness of aluminum silicate is equal, the temperature of the backfire surface decreases with the increase of the thickness of the air layer. This indicates that the presence of an air layer can serve as insulation, thereby affecting the fire resistance performance of composite sandwich panels.

　　雙鋼板混凝土組合剪力墻用板材：雙鋼板混凝土組合剪力墻采用 ALC 板或非膨脹型防火涂料進行保護，其結(jié)構(gòu)可以有效地阻止火勢蔓延，提高墻體的耐火性能。此外，增大栓釘和對拉螺栓間距、增大軸壓比等因素也會影響墻體的結(jié)構(gòu)穩(wěn)定性和耐火性能。

　　Double steel plate concrete composite shear wall panels: Double steel plate concrete composite shear walls are protected by ALC panels or non expanding fireproof coatings, which can effectively prevent the spread of fire and improve the fire resistance performance of the wall. In addition, factors such as increasing the spacing between bolts and tension bolts, and increasing the axial compression ratio can also affect the structural stability and fire resistance of the wall.

　　制作工藝的影響

　　The impact of production process

　　耐火纖維板：采用真空吸濾工藝制備耐火纖維板坯體，并分別使用微波干燥工藝和熱風干燥工藝進行干燥。研究表明，微波干燥纖維板在 800 和 1000℃時的熱導(dǎo)率略低于熱風干燥纖維板；微波干燥纖維板的耐壓強度、斷面硬度和磨后表面硬度均大于熱風干燥纖維板，但磨前表面硬度顯著小于熱風干燥纖維板；微波干燥纖維板面方向和厚度方向的收縮相對均勻，干燥速度遠大于熱風干燥；微波干燥纖維板中硅溶膠呈薄片狀分布在纖維之間，熱風干燥纖維板的則呈點狀附著在纖維上。這些差異表明制作工藝對耐火纖維板的性能有重要影響。

　　Refractory fiber board: The refractory fiber slab is prepared using vacuum filtration technology, and dried using microwave drying technology and hot air drying technology respectively. Research has shown that the thermal conductivity of microwave dried fiberboard is slightly lower than that of hot air dried fiberboard at 800 and 1000 ℃; The compressive strength, cross-sectional hardness, and surface hardness of microwave dried fiberboard are all higher than those of hot air dried fiberboard, but the surface hardness before grinding is significantly lower than that of hot air dried fiberboard; The shrinkage of the fiber surface direction and thickness direction in microwave drying is relatively uniform, and the drying speed is much faster than that of hot air drying; The silica sol in microwave dried fiberboard is distributed in thin sheets between the fibers, while in hot air dried fiberboard, it adheres to the fibers in dots. These differences indicate that the manufacturing process has a significant impact on the performance of refractory fiberboard.
