Abstract

The invention provides a preparation method of ceramic fibers. A formula of the ceramic fibers comprises the following components in parts by weight: 45 to 55 parts of silicon dioxide, 40 to 50 partsof aluminum oxide, 0.8 to 1 part of iron oxide, 0.1 to 0.25 part of sodium oxide and 0.1 to 0.25 part of potassium oxide; the preparation method comprises the following steps: a, weighing the materials and putting the materials into a melting furnace with the temperature of 2000 to 2500 DEG C and melting; b, carrying out thread throwing and fiber forming on the molten mixture through a thread throwing machine, wherein a thread throwing speed is 8000 to 10000r / min; c, conveying obtained fibers into a bulk material; forming a layer spreading structure through a conveyor belt; d, carrying out double-faced needling on bulk cotton with the layer spreading structure, so as to form original ceramic fibers with a certain tensile force; e, determining the nature of the original ceramic fibers through a high-temperature box with the height of more than ten meters; f, cutting and packaging the ceramic fibers with the determined nature. The preparation method of the ceramic fibers has the advantages that the prepared ceramic fibers have light weight and the whole quality of an industrial kiln furnace can be effectively reduced; the chemical stability is good and the chemical corrosion resisting capability is relatively strong.

Description

technical field [0001] The invention belongs to the technical field of ceramic fibers, in particular to a preparation method of ceramic fibers. Background technique [0002] With the continuous improvement of the country's scientific and technological strength, more and more high-precision equipment has been introduced or developed, and applied to production activities in various industries. As for the high-precision equipment used in high- and low-temperature environments, how to realize the design of the refractory and heat-insulating materials has become a key issue at present. Traditional refractory and thermal insulation materials are mainly divided into two categories: organic materials and inorganic materials. Organic thermal insulation materials are not suitable for thermal insulation of high-end equipment because of their low ignition point and easy ignition, which poses safety hazards. Contents of the invention [0003] The invention provides a method for prepar...
