Product description：
- Ceramic fiber shaped products, using high quality ceramic fiber cotton as raw materials, made by vacuum molding process. The purpose of the development of this product is to make rigid and self-supporting strength products with superior high temperature performance.
- Ceramic fiber special-shaped products, are to meet the specific production links of some industrial sectors required special-shaped products, each product according to its shape and size need to make a special mold, according to the performance requirements of the product, the selection of unused bonding agents and additives to meet the requirements of use.
- All shaped products have low shrinkage over their service temperature range and remain highly insulated, lightweight and impact-resistant.
- Materials that are not hot can be easily cut or machined. During use, the product has good resistance to wear and peeling and is not wetted by most molten metals.
- Shape and availability: Vacuum shaped shaped products can have a variety of sizes and shapes, including tube, cone, dome and square box shape, most shaped products can be produced according to customer requirements, but some shaped products can also be inventory for customers, such as non-ferrous metal industry with casting caps and sleeves, petrochemical industry with vacuum shaped fire holes.
- General characteristics: The physical and thermal characteristics of various shaped products are generally similar to the performance of the corresponding level of vacuum forming plates.
- Special treatment: If required, vacuum forming hardener or refractory mud can be applied to the shaped product to provide a protective layer.
