Description

[0002] In many industrial and civil fields, ceramic fillers are widely used due to their good heat insulation, heat preservation, fireproofing and other properties. However, traditional ceramic fillers have many shortcomings in structure design and performance. Traditional ceramic fillers are mostly in the form of single ceramic fiber material, and the processing equipment is relatively simple. Generally, ceramic raw materials are made into fibers through simple fiber drawing equipment, and then are simply stacked or compression molded. Such equipment can only meet the basic fiber production needs, and lacks control over fiber arrangement and structure optimization.

[0003] For the above-mentioned related technology, it is found that the traditional ceramic fiber filler has low overall strength due to its single structure, and the ceramic fiber is easily broken and damaged during the operation of workers during the construction process, which greatly reduces the filling effect. In the construction of building exterior wall insulation, the internal fibers of the traditional ceramic filler will be broken after being slightly impacted, which destroys the integrity of the insulation layer and reduces the heat insulation performance.

[0004] Secondly, the overall shear resistance is poor, and when the filling space is extruded and sheared by external force, the filler is prone to deformation and misplacement, which cannot maintain stable heat insulation effect, and the fibers will be gradually eroded and aged in long-term harsh environment, greatly shortening the service life.
