What are the main production methods for ceramic fiber board?

The main production methods for ceramic fiber board include the following: 1) Dry process, where raw materials are mixed and then formed into boards without the use of water. 2) Wet process, which involves mixing raw materials with water to form a slurry, then casting and drying to form boards. 3) Spray drying, where the raw materials are sprayed into a hot gas stream to create small particles that are collected and formed into boards. 4) Extrusion process, where the material is forced through a die to create a specific shape. Each method has its advantages and is chosen based on the desired properties of the final product, such as density, flexibility, and thermal resistance.
