Problems solved by technology

For example, ordinary ceramics have a large proportion, are easy to break, are not easy to cut, and are not resistant to rapid cooling and heat; plastics are not resistant to high temperatures, are easy to age, and have a short service life; metals have a large proportion, poor thermal insulation performance, and are not resistant to corrosion. High, and it is not conducive to the country's protection of forest resources, control of soil erosion and maintenance of ecological balance; composite materials are complex and expensive

Embodiment 1

[0013] The raw material formula is as follows by weight percentage: 60% of magnesia clay and 40% of fly ash.

[0014] Its technological process is to put the raw materials into a ball mill according to the above formula, add an appropriate amount of water for ball milling, and squeeze them dry to obtain the material. Then: 1. Various shapes of chemical fillers can be squeezed out with a vacuum mud mixer; 2. It can be kneaded into a spherical catalyst carrier; 3. It can be dried and pressed into a ceramic filter brick plate with a hydraulic press; 4. It can be made into a power plant Ceramic heat dissipation materials in cooling water towers; 5. It can be made into sound insulation materials on highways. Then, the above green bodies and materials are sintered to become light-weight ceramic products in different application fields.

[0015] Made of lightweight ceramic materials, the three main chemical components are SiO 2 71%, Al 2 o 3 9%, MgO20%.

Embodiment 2

[0017] The raw material formula is as follows by weight percentage: 20% of magnesia clay and 80% of fly ash.

[0018] Its technological process is with embodiment 1.

[0019] Made of lightweight ceramic materials, the three main chemical components are SiO 2 67%, Al 2 o 3 28%, MgO5%.

Embodiment 3

[0021] The raw material formula is as follows by weight percentage: 100% of magnesia clay and 0% of fly ash.

[0022] Its technological process is with embodiment 1.

[0023] Made of lightweight ceramic materials, the three main chemical components are SiO 2 72%, Al 2 o 3 3%, MgO25%.

Abstract

The invention relates to a lightweight ceramic material, which is prepared from magnesium soil and pore former through the steps of proportioning, ball grinding, squeezing, forming, drying and sintering. The material has the advantages of light weight, quench resistance, high intensity, strong corrosion stability, non-deformation, good heat-insulating property, and sound insulation performance.

Description

technical field [0001] The invention relates to a ceramic material and its manufacturing method and application, which can be used in the fields of chemical industry, metallurgy, energy, environmental protection, transportation, building materials and the like. Background technique [0002] In the prior art, materials that can be used in the fields of chemical industry, metallurgy, energy, environmental protection, transportation, building materials, etc. include ordinary ceramics, plastics, metals, wood, and other composite materials, each of which has its own shortcomings. For example, ordinary ceramics have a large proportion, are easy to break, are not easy to cut, and are not resistant to rapid cooling and heat; plastics are not resistant to high temperatures, are easy to age, and have a short service life; metals have a large proportion, poor thermal insulation performance, and are not resistant to corrosion. High, and it is not conducive to the country's protection of...
