ZIBO SK refractory mortar is a new kind of paste-like bonding material which is formed particularly from specially sorted powder made from the identical raw materials and classification temperatures in light with the brick utilized in furnace and their refractory grades. During the process of production, it undergoes chemical reaction and stirring-up with added inorganic bonding agent and additives. ZIBO SK refractory mortar can be classified into four categories according to its service temperature in normal circumstances and they must be used to support the lightweight mullite brick subject to the same class.

Firebricks in the furnace lining
ZIBO SK ceramic fiber blanket presents unparalleled refractories and thermal insulation due to its long spun fiber needling technique. These blankets offer superior insulating performance, flexibility and resilience. ZIBO SK ceramic fiber blanket products are unaffected by most chemicals (except hydrofluoric & phosphoric acids and concentrated alkali). Thermal and physical properties are retained after drying following wetting by oil, steam or water. ZIBO SK ceramic fiber blankets are completely inorganic, so there are no fumes when heating for the first time.
Features
High tensile strength and shrinkage
Good resiliency with low heat storage
Low thermal conductivity
Thermal shock resistance
Good sound absorption
Typical Applications
Annealing furnaces
Furnace door linings and seals
Soaking pit covers and seals
Furnace hot face repairs
Reheating furnace and ladle covers
ZIBO SK ceramic fiber board is manufactured and designed for the thermal applications requesting high demands on rigidity, the thermal insulation properties and abrasion resistance of ceramic fiber board have been further improved due to the higher density. Ceramic fiber board is a vacuum formed product that resists higher gas velocities than ceramic fiber blanket. It is ideal for furnace, boiler duct and stack lining thanks to its low thermal conductivity and low heat storage, which makes the shorter cycle times and quicker access for maintenance in the industrial furnaces possible.
Features
High rigidity and light weight
Low thermal conductivity
Resistance to thermal shock and gas erosion
Easy cutting and engineering, mechanical flexibility
Resists penetration by molten alumina and other non-ferrous metals
Typical Applications
Refractory lining for industrial furnaces
Combustion chamber liner,boilers and heaters
Back-up insulation for monolithic refractories
Transfer of non-ferrous metals
Expansion joint boards
Barrier against flame
Ceramic fiber textiles contain the rope, tape, yarn and cloth. ZIBO SK ceramic fiber textiles are woven or braided from yarn consisting of refractory ceramic fiber with approximately 20% organic fiber. Inserted materials are reinforced into the yarn to increase the tensile strength of fibers. Stainless steel inserts are available for obtaining maximum strength at high temperatures. Glass filament inserts are used in applications where electrical resistance is required, ZIBO SK ceramic fiber textiles have been a workable insulation materials for thermal gaskets and wrapping, its unique functions and features are gaining more popularity in the high temperature insulations.
