Production Process
01. Raw Material Preparation
High-quality soluble ceramic fibers, inorganic binders, and auxiliary additives are strictly selected to ensure material purity and accurate proportioning.
02. Ingredient Mixing
Ceramic fibers and inorganic binders are uniformly mixed. Appropriate water is added to form a homogeneous slurry through wet stirring.
03. Board Forming
Specialized forming equipment is used for wet-process molding to ensure a uniform and dense board structure.
04. Pressing and Shaping
Mechanical pressing is applied to densify the board, ensuring precise dimensions and thickness.
05. Drying and Curing
A continuous drying oven is used for high-temperature drying to promote the curing of inorganic binders and enhance board strength.
06. Inspection and Packaging
Quality tests, including density, strength, and temperature resistance, are conducted. Qualified products are then packaged for shipment.
