AI Technical Summary

Problems solved by technology

Traditional fire-resistant and thermal insulation materials are mainly divided into two categories: organic materials and inorganic materials. Organic thermal insulation materials are not suitable for high-end equipment thermal insulation due to their low ignition point and easy fire hazards.

preparation example Construction

[0013] The preparation method of this ceramic fiber comprises the following steps:

[0014] a. take above-mentioned batching and put into the melting furnace that temperature is 2000-2500 and melt;

[0015] b. The above-mentioned molten mixture material is spun into fibers through a spinning machine, and the speed of spinning is 8000-10000r / min;

[0016] c. The above-mentioned obtained fibers are gathered into the brocade cotton anise, and a layered structure is formed by a conveyor belt;

[0017] d. The loose brocade cotton of above-mentioned layered structure is carried out double-sided acupuncture through acupuncture machine, forms the original ceramic fiber of certain pulling force;

[0018] e. The above-mentioned original ceramic fiber is qualitatively passed through a high-temperature box of more than ten meters continuously;

[0019] f. Cut and pack the qualified ceramic fibers.

Abstract

The invention relates to a ceramic fiber which comprises the following components in part by weight: 45-55 parts of silicon dioxide, 40-50 parts of aluminum oxide, 0.8-1 part of ferric oxide, 0.1-0.25part of sodium oxide and 0.1-0.25 part of potassium oxide. The ceramic fiber provided by the invention has the advantages that the prepared ceramic fiber is light in weight, capable of effectively reducing the overall quality of an industrial kiln, excellent in chemical stability, stronger in chemical erosion resistance, very outstanding in thermal shrinkage and cold expansion, excellent in tensile strength, capable of adapting to the heat preservation of most of kilns and equipment, low in thermal capacity, low in thermal conductivity and excellent in sound absorption and noise reduction performances.

Description

technical field [0001] The invention belongs to the technical field of ceramic fibers, and in particular relates to a ceramic fiber. 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 present invention provides a kind of ceramic fibe...
