Abstract
Description
Technical Field
[0001] The invention relates to a method for preparing a novel ceramic process material. Background Art
[0002] Moon bricks are a type of building material that may be used to build houses on the moon in the future. Moon bricks have a mortise and tenon structure, which is conducive to assembly in the construction of future lunar bases. The compressive strength of moon bricks is more than three times that of ordinary red bricks and concrete bricks, which is equivalent to being able to withstand more than 1 ton of weight per square centimeter.
[0003] The production of lunar bricks adopts the vacuum hot pressing sintering method. The whole process includes weighing, pressing, and high-temperature firing of simulated lunar soil, ensuring that the lunar bricks are 100% in-situ formed without any other material additives. Now scientists have solved the material problem for building houses on the moon, but because the soil on the surface of the moon is mainly composed of rock debris, single mineral particles, glass, etc., there are natural iron, gold, silver, lead, zinc, copper, antimony and other mineral particles, and the loose and rough texture is similar to the appearance of cement on the earth, which is gray. Without any added materials, the bricks are purely shaped by high temperature firing of more than 1000 degrees, which is sufficient for outdoor conditions in the lunar environment, and are relatively simple in terms of color and aesthetics.
[0004] Therefore, a preparation method of a new type of ceramic process material is proposed. Summary of the invention
[0005] The present invention provides a method for preparing a new type of ceramic process material. By exploring the cost, material and process, a new ratio is found to prepare a ceramic material suitable for lunar life. The ceramic material has the characteristics of corrosion resistance, high density, high hardness and beautiful appearance.
[0006] A method for preparing a new type of ceramic process material, comprising mixing simulated lunar soil and clay in a ratio of 1:5, adding appropriate amount of water and single minerals, and kneading the mixture to form a mixed mud mass;
[0007] The mixed mud is dried in the shade at room temperature for 5-7 days, then shaped on a porcelain throwing plate. After glazing, it is fired in a 1200-degree electric boiler used in ordinary porcelain making to make ceramic craft materials.
[0008] Preferably, the main components of the simulated lunar soil of the present invention include mineral fragments, original crystalline rock fragments, breccia fragments, various glasses, a unique lunar soil component - bonded agglomerate rock, and meteorite fragments.
[0009] Preferably, the single mineral of the present invention is at least one of pyroxene, augite, labradorite and ilmenite.
[0010] The new ceramic process material of the present invention is based on the same firing process of simulated lunar soil and clay in appropriate proportions to obtain vessels adapted to the lunar environment. It is safe to use and has the characteristics of corrosion resistance, high density, strong hardness and beautiful appearance. DETAILED DESCRIPTION
[0011] The simulated lunar soil used in the present invention is purchased from Canada's SITECO. It is an artificial material with similar mineral composition, chemical composition and engineering mechanical properties to real lunar soil. It is also the main experimental material for the current development and utilization of lunar resources and lunar science research at home and abroad.
[0012] The main elements of the simulated lunar soil SC-071 and the lunar soil during the Apollo period were compared, see Table 1. The simulated lunar soil can replace the lunar soil for experiments.
[0013] Table 1 Comparison of main elements between simulated lunar soil SC-071 and lunar soil during the Apollo period
[0014]
[0015] A method for preparing a new type of ceramic process material, comprising mixing simulated lunar soil and clay in a ratio of 1:5, adding appropriate amount of water and single minerals, and kneading the mixture to form a mixed mud mass;
[0016] The mixed mud is dried in the shade at room temperature for 5-7 days, then shaped on a porcelain throwing plate. After glazing, it is fired in a 1200-degree electric boiler used in ordinary porcelain making to make ceramic craft materials.
[0017] Preferably, the main components of the simulated lunar soil of the present invention include mineral fragments, original crystalline rock fragments, breccia fragments, various glasses, a unique lunar soil component - bonded agglomerate rock, and meteorite fragments.
[0018] Preferably, the single mineral of the present invention is at least one of pyroxene, augite, labradorite and ilmenite.
[0019] 50 grams of simulated lunar soil was added to 250 grams of clay (kaolin) in a ratio of 1:5 and mixed and kneaded. The roughness of the hand feel can meet the requirements of the embryo pulling process. It can be judged from the embryo pulling on the wheel that the vessel pulled out of this ratio can ensure the complete fusion of the two soils without cracks, and the vessel forming degree is also very high. After being fired at a boiler temperature of 1200 degrees, the most common and commonly used porcelain firing, a fine porcelain plate with a diameter of 15 cm can be fired. The appearance of the disk is similar to that of antique utensils, with a clear and natural granular feel. The metal elements in the clay, such as iron, copper, and gold, have a little kiln change at high temperature, producing red and brown spots with a nostalgic and retro beauty.
[0020] The main components of simulated lunar soil include mineral fragments, original crystalline rock fragments, breccia fragments, various glasses, unique lunar soil components - bonded agglomerates, meteorite fragments, etc. These components are similar to the mineral composition and chemical composition of lunar samples, and have similar particle size, mechanical strength, porosity, density and electrical properties. The mineral composition of simulated lunar soil SC-071 and lunar soil during the Apollo period is compared in Table 2.
[0021] Table 2 Comparison of mineral composition between simulated lunar soil SC-071 and lunar soil during the Apollo period
[0022]
[0023] In addition, specific minerals will be added to further match the chemical and mineral composition. For example, by adding single minerals such as calcium iron pyroxene, common pyroxene, labradorite, and ilmenite, simulated lunar soil can be developed. Simply put, it is a mixture containing rock fragments, single mineral particles, glass, and mineral particles such as iron, gold, silver, lead, zinc, copper, and antimony.
[0024] According to the hardness test of Foshan Ceramic Research Institute Testing Co., Ltd., the Vickers hardness HV5 reaches 7.3GPa. It is speculated that the change in hardness is related to the content of metal trace elements in the lunar soil. Because the lunar soil contains more metal elements, rock fragments, single mineral particles, etc., mixing with kaolin to fire porcelain will reduce the density of porcelain mud to a certain extent, thereby reducing the hardness of the vessel. The simulated lunar soil and clay are mixed in a ratio of 1:5 and fired at a high temperature of 1200 degrees. The plasticity, aesthetics, hardness and texture of the plate are in line with the industry standard value of 5-9CPa of the national standard ceramic Vickers hardness, which is higher than ordinary red bricks or cement bricks and clay engineering materials.
[0025] The metal elements in the lunar soil will produce oxidation reactions during high-temperature firing, and the porcelain will be colored. Similar in appearance to ancient antique porcelain, its materials have certain breakthroughs in the fields of ceramic art, cultural relics restoration, and new materials. Gaobai porcelain is a kind of porcelain made from local high-quality kaolin and other raw materials, which is refined and prepared, and fired at high temperature. The porcelain glaze is pure and delicate, noble and flawless, snow-white and elegant, and ice-like. Kaolin: It is mainly composed of kaolinite, halloysite, hydromica, illite, montmorillonite, quartz, feldspar and other minerals, containing a large amount of silicon, aluminum and oxygen elements, among which aluminum is one of the main components of kaolin. In addition to silicon and aluminum, the most common elements are calcium, magnesium, sodium, potassium and iron. Whether it is hardness, beauty, or density, porcelain vessels have been verified by thousands of years of use.
[0026] A comparison was made between plate A made of 100% white porcelain mud and plate B made of simulated lunar soil mixed with kaolin in a ratio of 1:5. Plate A is not as dense and hard as plate B. Because the pressure resistance of simulated lunar soil is 3 times higher than that of red bricks and concrete, which is equivalent to 1 square centimeter bearing a weight of 1 ton. The hardness of this plate is higher than that of plate A, and the aesthetics is improved compared to the color of bricks fired with 100% lunar soil. The firing process is the same as the firing process of daily porcelain, which achieves cost control and is also capable of mass production of other types of vessels. In addition, kaolin mining is also restricted every year, and the earth's energy is also decreasing. Such a new type of ratio material is needed for the exploration of aerospace industry.
[0027] The lunar soil was mixed with clay to prepare pure lunar soil group, high lunar group, middle lunar group, low lunar soil group and pure clay group, and then fired into finished products. The finished product obtained by firing the lunar soil alone was the pure lunar soil group; the finished product obtained by firing the lunar soil and clay in a ratio of 5:1 was the high lunar group; the finished product obtained by firing the lunar soil and clay in a ratio of 1:1 was the middle lunar group; the finished product obtained by firing the lunar soil and clay in a ratio of 1:5 was the low lunar soil group; the finished product obtained by firing the clay alone was the pure clay group. The sample density, apparent porosity and water absorption rate of the finished products obtained in each group were tested, and the following results were obtained: sample density: pure lunar soil group < high lunar group < middle lunar group < low lunar soil group < pure clay group; apparent porosity and water absorption rate: pure lunar soil group > high lunar group > middle lunar group > low lunar soil group > pure clay group.
[0028] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
