Aluminum Silicate Refractory Fiber Products

Aluminum Silicate Refractory Fiber Products

Aluminum silicate refractory fiber products can be directly used as a filling material for high temperature insulation, but the most commonly used are various refractory fiber products processed by different methods. Among aluminum silicate refractory fiber products, refractory fiber blankets, felts, paper, and vacuum forming products are the most used and used.

Refractory Fiber Blanket

Refractory fiber blanket is a flexible high-quality thermal insulation material, which has many advantages: such as low temperature resistance, low thermal conductivity, low thermal conductivity, good insulation performance, easy cutting and processing and construction of thermal insulation linings for kilns. In terms of energy saving, construction and benefits, the fire-resistant fiber blanket has particularly outstanding advantages.

Vacuum Formed Refractory Fiber Products

Vacuum-formed refractory fiber products are rigid or semi-rigid refractory products produced by vacuum wet molding with refractory fiber raw cotton as the main raw material. In production, according to the different physical and chemical performance requirements of the finished product, the appropriate varieties of refractory fibers, binders, fillers, flocculants, etc. are selected and mixed with water to form a slurry, and adjusted to a certain concentration and PH value. Then it is injected into a mold with a filter screen, vacuumed and dehydrated, molded, demolded, dried, and finally processed to obtain a finished product.

Vacuum Formed Plug

Refractory fiber is the main structural material in vacuum-formed refractory shapes. It determines the basic performance of the product. According to different requirements, Xitong aluminum silicate refractory fiber, high alumina refractory fiber, zirconium-containing refractory fiber, and polycrystalline alumina can be used fiber.

The binding agent can be silica sol, aluminum dihydrogen phosphate, carboxymethyl cellulose, and aluminum sulfate. Fillers include clay, high-alumina clinker powder, alumina powder, expanded perlite, and fused silica. Vacuum wet molding technology can be used to produce various refractory fiber products with complex shapes, such as refractory fiber felt and board. Runners, riser sleeves, pipe sleeves for metal casting, kiln burner blocks, fire holes, plug hole cones, and various thermal insulation pads, etc., used in non-ferrous metal smelting, casting, ceramics, petrochemical, aviation, and instrumentation And other industries have a wide range of uses.

Refractory Ceramic Fiber Paper

Refractory ceramic fiber paper uses refractory fiber cotton as the main raw material, and is a paper-like material with uniform structure and good flexibility produced by conventional papermaking technology. In the production of refractory ceramic fiber paper, refractory cottons with different classification temperatures are used, such as ordinary type, high purity type, high aluminum type, zirconium-containing type, etc. as the main raw materials, and appropriate matching, the composition use temperature (℃) is 600, 800, Main structural fibers of different grades such as 1000, 1100, 1200, etc.
