Embodiment 1

[0034] Fully mix 450 kg of shale, 10 kg of caustic soda, 16.1 kg of borax, 4.5 kg of calcium carbonate powder, 1.9 kg of carbon powder, and 17.5 kg of mica. The chemical composition of the shale used is (in weight percent): SiO 2 59.64%, Al 2 o 3 15.08%, Fe 2 o 3 7.91%, CaO 2.96%, MgO 2.13%, impurities 7.49%. Then the mixture was crushed to 150 mesh, 6 kg of heavy oil was added to the mixture, and the mixture was made into uneven particles with an average size of 0.8 cm using a granulator. The prepared mixture particles are loaded into a mold, and the surface of the mold is coated with a magnesite release agent. The mold is then fired in a tunnel kiln, the temperature is raised to about 1160°C for 35 minutes. Then annealed for 14 hours, and then demolded to obtain 1 meter of artificial pumice. Cut the artificial pumice stone to the desired size as needed.

Embodiment 2

[0036] Fully mix 440 kg of diatomite, 11.3 kg of caustic soda, 16.5 kg of borax, 5.6 kg of calcium carbonate powder, 4.1 kg of carbon powder, and 22.5 kg of mica. The chemical composition of diatomaceous earth used is (by weight percentage): SiO 2 68.45%, Al 2 o 3 19.70%, Fe 2 o 3 2.40%, CaO 1.04%, MgO 0.81%, impurities 7.60%. The mixture was then pulverized to 130 mesh. The obtained mixture is filled into a mold, and the surface of the mold is coated with a phosphatite release agent. The mold is then put into a tunnel kiln for firing, and the temperature is raised to 1120° C. for 40 minutes. Then annealed for 18 hours, followed by demoulding to obtain 1.2m 3 artificial pumice. Cut the artificial pumice stone to the desired size as needed.

Abstract

The invention relates an approach to produce artificial pumice. It is burned by nether materials: inorganic material, sodium hydroxide, borax, Paris white, carbon dust and isinglass. Thereinto, inorganic material is selected from minerals or clay. It follows nether steps: mixing above materials in terms of given ratio, cracking blending to 60-200 items and loading into a module to bake.

Description

technical field [0001] The invention relates to an artificial pumice, in particular to an artificial pumice fired from inorganic materials, a flux, an expansion agent and a linking agent, and a manufacturing method of the artificial pumice. Background technique [0002] With the continuous improvement of people's living standards and the rapid development of the construction industry, higher requirements are placed on building materials. Modern buildings not only require good building quality and perfect use functions, but also require buildings to have ecological and environmental protection functions such as energy saving, temperature adjustment, sterilization, and health care. In addition, the building materials industry consumes a lot of energy, and building energy consumption is far greater than the production capacity of building materials used in buildings. Therefore, reducing building energy consumption has become a major concern of countries all over the world. The...
