2. Core Process Flow
（1）Raw Material Preparation:
Ceramic fiber raw materials (e.g., short fibers produced by melt-blown method) are crushed, purified, and mixed with binders and dispersants according to the formula.
Ceramic fiber raw materials (e.g., short fibers produced by melt-blown method) are crushed, purified, and mixed with binders and dispersants according to the formula.
（2）Pulping:
Fibers are fully dispersed in water in the pulping machine to form a uniform slurry (1–3% concentration; fiber length 0.5–3 mm).

（3）Papermaking/Forming:
Slurry is evenly spread on the forming wire through a headbox, vacuum-dewatered, and pressed by rollers to form wet paper sheets (thickness 0.5–5 mm).

（4）Drying and Curing:
Wet sheets are conveyed into a drying oven. Hot air or infrared heating reduces moisture to below 3% while curing the binder to strengthen fiber bonding.
