Embodiment Construction

[0019] 1. Ingredients: Add 80 kg of aluminum silicate fiber, 70 kg of organic binder, 15 kg of inorganic binder and 80 kg of additive into the mixing tank respectively;

[0020] 2. Start stirring to fully stir and make pulp, and keep the slurry concentration at 2-6%;

[0021] 3. Put the prepared slurry into the forming tank, turn on the vacuum suction filter equipment, and vacuum form the cotton pulp into a slab by vacuuming;

[0022] 4. Send the slab to the drying kiln for hot air drying at a drying temperature of 110-150°C;

[0023] 5. Mechanically process the dried slab into products of various specifications, sizes and shapes;

[0024] 6. After the product is packaged, it becomes a 700kg / m3 high-density board product.

[0025] Performance comparison with ordinary ceramic fiberboard:

[0026] Ordinary ceramic fiberboard flexural strength (MPa): 1.2, compressive strength (MPa): 0.25, hardness: 73, bulk density (kg / m3): 310.

Abstract

A ceramic fiber board is characterized by consisting of aluminium silicate fiber, an organic bonding agent, an inorganic bonding agent and an additive; and the ceramic fiber board comprises the following components by weight: 10 to 80 portions of the aluminum silicate fiber, 12 to 70 portions of the inorganic bonding agent, 1 to 15 portions of the organic bonding agent and 0 to 80 portions of the additive. Processing steps of the ceramic fiber board comprise mixture, molding and drying. The ceramic fiber board has the advantages that the production process has no process of compression molding, so the ceramic fiber board greatly reduces the equipment investment, labor cost, fields and the like, simplifies the process of production technology and improves the service performance and high temperature performance, and mechanical equipment can be used to process products randomly.

Description

technical field [0001] The invention relates to the field of ceramic fiber boards. Background technique [0002] The bulk density (density) of the current vacuum-formed ceramic fiberboard products is generally below 400kg / m3, and the various indicators of the products are: flexural strength less than 2.0MPa; compressive strength less than 0.6MPa. 400kg / m, the production process of the product is: 1 preparation of slurry: mix ceramic fiber cotton, filler and binder evenly to make a suitable slurry; 3 Compression molding: Put the slab that has drawn out part of the moisture on the pressure forming machine, press out part of the moisture with high pressure, and reduce the thickness to increase the bulk density; 4 Drying: The compressed slab enters the drying process The equipment discharges the moisture in the slab; 5. Machining: machine the dried slab to produce various products; 6. Packing: Pack the product in a suitable way. The shortcomings of such a production method are...
