Aluminum silicate white fiber wool
| |
FUERDA common aluminum silicate fiber wool is made of hard clay clinker as raw material which will be long fiber by melting and blowing of electric resistance furnace with low content of slag ball and non-fibrous matters. The long fiber without processed is the filling materials of wall lining space of high-temperature kiln heating device and excellent raw materials of textiles because of spinnability.
Technical characteristics: 1. Low heat conductivity and thermal capacity 2. No corrosive substance 3. Excellent heat insulation and sound absorption
Scope of application: 1. Raw materials of fiber paper and vacuum molding products 2. Raw materials of fiber painting 3. Raw materials of fiber castables and coating 4. Filling materials of wall lining space of high-temperature kiln heating device 5. Raw materials of fiber textiles
Aluminum silicate fiber rope: It is a new kind of elastic glass fiber rope with innovated weave. Because of strong contractibility, it is widely used as filling materials, and soft joint between boiler and furnace wall or body. Also it is used as heat insulation materials for motor, meter and electric appliance due to excellent insulation and heat resistance.? temperature resistance
Technical characteristics: 1. High working temperature; it can be 1000¡æ for long-term working and 1200¡æ for short-term. 2. Resistance to acids, aluminum and zinc erosion. 3. Low heat conductivity; good heat preservation; strong high-temperature resistance. 4. Ceramic fiber products with strengthened alkali free fiberglass have excellent high-temperature electric insulation. 5. Healthy, nontoxic and odorless.
High-temperature adhesives special for aluminum silicate FUERDA high-temperature adhesives are a kind of better inorganic adhesive materials. It has the outstanding advantages of easy construction, high- temperature resistance, great cohesional strength, strong resistance to sinter erosion, high stability, long lifetime, and wide application. It can be used as bonding agent of irregular fire-resisting materials and used for sticking and mending of approved fireproof products. At the same time, we can offer strengthened protective paintings for high-density mud and special working parts.
Fire-resisting components of aluminum silicate It is also called fire-resisting fiber prefabricated components. According to the structure, it is divided into three catalogues: model'Z' components of fire-resisting fiber, model "U" components and standard blanket-folded components.
Technical characteristics: 1. Excellent chemical stability 2. Excellent thermal stability 3. Fine elasticity (because fiber is in the condition of precompression, its expansion can compensate fiber constriction and heighten heat insulation of fiber furnace lining.) 4. Low heat conductivity and thermal capacity.
Scope of application: It is widely used in furnace lining of various industrial furnace and heating device in metallurgy, mechanism, ceramics, building materials, petroleum and chemical industry.
