Description

Technical Field

[0001] This utility model relates to the field of refractory fiber composite material technology, specifically a high-temperature and corrosion-resistant polycrystalline alumina fiber composite structure. Background Technology

[0002] Polycrystalline alumina fiberboard is mainly used in high-temperature insulation, composite material reinforcement, and chemical corrosion resistance. It has characteristics such as low thermal conductivity and high heat resistance. The fire-resistant fiber modules used in general working temperatures of 1100-1250℃ are mostly made of zirconium-containing fiber materials. If the working temperature is 1250-1350℃, polycrystalline alumina fiber materials with higher fire resistance are required. However, polycrystalline alumina fiber materials are more expensive. Generally, a composite structure material combining zirconium-containing fiber materials and polycrystalline alumina fiber materials is used, with the polycrystalline alumina fiber material covering the outside of the zirconium-containing fiber material.

[0003] Conventional composite structural materials are fixed during installation by anchor rods penetrating the composite material. However, the location of the anchor rod penetration can lead to a decrease in fire resistance and heat insulation performance, thereby affecting the overall performance of the composite structural material. To address this, we propose a high-temperature and corrosion-resistant polycrystalline alumina fiber composite structure. Utility Model Content
