Ceramic fiber spray coating

Fiber spray lining is a ceramic fiber application technology that has evolved from traditional ceramic fiber‑based techniques, drawing on the spray‑application processes used for refractory powders and granules. In this process, ceramic fibers are treated with specialized spraying equipment; high‑pressure air conveys the processed fibers to the spray nozzle, where they are uniformly mixed with an atomized binder emitted from nozzles surrounding the spray head, before being applied to the working surface to form a sprayed ceramic fiber lining. Factors influencing the performance and effectiveness of ceramic fiber spray coatings include the content of slag balls in the ceramic fibers, fiber length, the uniformity of binder coating on the fiber surface, the design of anchoring elements, and the preparation of the substrate surface.

Product Description

Product Description:
◎ Fiber‑sprayed furnace linings are a ceramic fiber application technology developed on the basis of conventional ceramic fiber‑application techniques, drawing inspiration from the spray‑applied processes used for refractory powders and granules. In this process, ceramic fibers are processed using specialized spraying equipment; high‑pressure air conveys the treated fibers to the spray nozzle, where they are uniformly mixed with an atomized binder emitted from nozzles surrounding the spray head before being applied to the working surface, thereby forming a sprayed ceramic fiber lining.
◎ Factors influencing the performance and application effectiveness of ceramic fiber spray coatings include the content of ceramic fiber slag balls, fiber length, the uniformity of binder coating on the fiber surface, the design of anchoring elements, and the treatment of the substrate surface.

Ceramic fiber blanket

◎ Ceramic fiber blankets are produced continuously and, after needle-punching, feature uniformly interwoven fibers with high tensile strength, containing no binders. ◎ Needle-punched blankets of varying bulk densities and thicknesses offer users a wide range of material options to achieve optimal insulation performance and cost-effectiveness. ◎ Ceramic fiber blankets exhibit excellent resistance to chemical attack (except for hydrofluoric acid, phosphoric acid, and strong alkalis such as Na2O and K2O). ◎ The performance of ceramic fiber blankets is unaffected by oil exposure; their thermal and physical properties can be fully restored upon drying.

Ceramic fiber wet-laid felt

Ceramic fiber vacuum‑formed wet‑laid felt is manufactured using ceramic fiber wool produced by the resistance‑fused blow‑spinning process, and is shaped via a vacuum‑forming technique. ◎This ceramic fiber vacuum‑formed wet‑laid felt is a lightweight, flexible refractory fiber insulation material, composed of high‑purity refractory oxides combined with an organic binder. ◎In addition to inheriting the excellent properties of its loose‑fill counterpart, this product also exhibits superior strength and elasticity, making it a versatile material. It is suitable for expansion joints in furnace and boiler linings as well as for high‑temperature gaskets. When used as a gasket, its outstanding resistance to molten metal penetration makes it ideal for sealing ingot ladle bottoms, plug‑rod core gaskets, and aluminum billet casting gaskets.
