Abstract

The invention relates to the technical field of superfine ceramic cellucotton, and in particular, relates to superfine ceramic cellucotton and a production method thereof; the superfine ceramic cellucotton is prepared from fly ash, coal gangue waste, an old aluminum silicate thermal insulation material and kaolin through the steps of heating melting, conveying, centrifuging, blowing and the like;the prepared superfine ceramic cellucotton has the advantages of being low in production cost and more uniform in forming thickness.

Description

technical field [0001] The invention relates to the technical field of ultrafine ceramic fiber cotton, in particular to an ultrafine ceramic fiber cotton and a production method thereof. Background technique [0002] Aluminum silicate fiber has the characteristics of low thermal conductivity, high temperature resistance, corrosion resistance and high strength, and is widely used in the field of thermal insulation materials. In recent years, this fiber has been used to prepare a new thin layer of thermal insulation, especially in thermal insulation parts that require light weight and limited space, this material has been most effectively used. [0003] In the existing aluminum silicate fiber production process, the molten liquid material is usually flowed out from the melting pot to form a stable stream, which flows into the centrifuge, and the centrifuge rotates at a high speed, and the liquid material is discharged through the throwing port on the centrifuge. After being t...
