Description

Technical Field

[0001] This invention relates to the field of ceramic preparation technology, and in particular to a preparation process for functional ceramics with mixed trace elements. Background Technology

[0002] Ceramics, as an inorganic non-metallic material formed by calcination at a specific temperature, have been widely used in various fields, such as daily necessities, building materials and electronic equipment, due to their excellent hardness, high temperature resistance, electrical insulation and corrosion resistance. Most traditional ceramic products are produced and applied based on their inherent properties, and their deeper potential functions have not yet been fully utilized.

[0003] In recent years, with increasing attention to health and diet, ceramic cooking utensils and tableware have become increasingly important in our lives. Studies have shown that certain trace elements are beneficial to the human body, improving bodily functions, boosting immunity, and enhancing physiological functions. Therefore, how to incorporate these beneficial elements into ceramic products so that they can be gradually released during cooking or drinking to bring benefits to the human body has become a new research direction.

[0004] Although there are techniques for adding trace elements to ceramics, most methods involve simply adding trace element powder or solution during the ceramic making process. The problem with these methods is that the distribution of the elements may be uneven, or their beneficial properties may be destroyed during high-temperature calcination. This may not only lead to unstable ceramic performance, but may also affect the efficiency of releasing the elements.

[0005] Therefore, this invention provides a preparation process for functional ceramics with mixed trace elements. Through this unique process, trace elements can be evenly distributed in the ceramic and maintain their beneficial properties during high-temperature calcination. The ceramics prepared in this way can gradually release these elements that are beneficial to the human body during the process of cooking soup or food, thereby improving human function. Summary of the Invention

[0006] To achieve the above objectives, the present invention provides a preparation process for functional ceramics containing mixed trace elements.

[0007] A preparation process for a multi-trace element functional ceramic includes the following steps:

[0008] S1: Minerals containing multiple elements are extracted from selected raw ore;

[0009] S2: Mixing multiple elements extracted from the raw ore and transforming them into a multi-liquid mixture;

[0010] S3: Heating the untreated ceramic blank to 800 degrees Celsius;

[0011] S4: Place the heated adobe bricks indoors to cool naturally to 30 degrees Celsius;

[0012] S5: After cooling, use the atomization method to inject the multi-liquid mixture prepared in step two multiple times. After each injection, it needs to be dried. A total of 3-5 injections are performed until the mixture is completely absorbed into the adobe brick.

[0013] S6: Ultrasonic treatment is applied to the atomized soil bricks to promote deeper penetration of trace elements;

[0014] S7: Use infrared light to irradiate the adobe bricks to improve the bonding force between trace elements and the adobe bricks;

[0015] S8: The treated clay blanks are calcined a second time to form multi-trace element functional ceramic products.

[0016] Furthermore, the step of extracting minerals containing multiple elements in step S1 includes:

[0017] S11: Using screening technology, select raw ore with a particle size of 1mm for further processing;

[0018] S12: The screened raw ore is soaked in a dilute sulfuric acid solution with a pH of 2 for 12 hours in order to dissociate trace elements in the mineral;

[0019] S13: Using centrifugation technology, the solution containing trace elements is separated at a speed of 2000 revolutions per minute for 15 minutes;

[0020] S14: Dilute this solution to a ratio of 1:5 with distilled water, and then further purify it using reverse osmosis technology to obtain a mineral solution containing multiple elements.

[0021] Furthermore, the specific steps in step S2 of mixing multiple elements and converting them into a multi-liquid state are as follows:

[0022] S21: Take out the mineral solution containing multiple elements obtained in step S1, determine its concentration, and ensure that the element concentration is 10 g / L;

[0023] S22: According to the required element ratio, mix the different element solutions at a volume ratio of 1:1 and keep mixing for 20 minutes to form a mixed solution A;

[0024] S23: Add 5-10% of a polymeric stabilizer, such as carboxymethyl cellulose or pectin, to mixed solution A to enhance the stability of the liquid;

[0025] S24: Next, mix solution A is stirred on a magnetic stirrer at a speed of 500 revolutions per minute for 1 hour to form a homogeneous liquid mixture B;

[0026] S25: While maintaining a pH of 6, slowly add 5-8% of an emulsifier, such as phospholipid or egg yolk lecithin, to liquid mixture B, and continue stirring for 45 minutes to transform liquid mixture B into a multi-liquid mixture.

[0027] Furthermore, the high-temperature heating step in step S3 specifically includes:

[0028] S31: First, ensure that the adobe bricks are dry to over 95% and then place them in an electric resistance furnace;

[0029] S32: Slowly increase the temperature at a rate of 30°C per hour until the temperature inside and outside the adobe brick reaches a uniform 800°C.

[0030] S33: After reaching 800 degrees Celsius, maintain this temperature and continue heating for at least 1 hour to ensure that the microstructural changes and chemical reactions inside the adobe are completed.

[0031] Furthermore, the step of allowing the heated adobe bricks to cool naturally indoors in step S4 specifically includes:

[0032] S41: After removing the heated adobe bricks, place them in an environment with a room temperature of 25 degrees Celsius and a humidity of 55%.

[0033] S42: Use heat insulation racks to ensure that the adobe bricks have minimal direct contact with other surfaces in order to promote uniform cooling;

[0034] S43: Use thermal imaging to monitor the temperature of the adobe bricks in real time to ensure that they cool down uniformly and stably to 30 degrees Celsius;

[0035] S44: Avoid any form of mechanical intervention or accelerated cooling throughout the cooling process to ensure the stability of the microstructure inside the adobe and to prevent surface cracking.

[0036] Furthermore, the step S5, which involves injecting the multi-liquid mixture using an atomization method, specifically includes:

[0037] S51: Use an atomizing nozzle with a particle size of 4-6 micrometers to ensure that the mixture can form uniform tiny water droplets;

[0038] S52: Set the distance between the nozzle and the adobe brick to within 15-20 cm to ensure that the atomized liquid evenly covers the surface of the adobe brick;

[0039] S53: Adjust the working pressure of the atomizing nozzle to 2-3 bar and maintain the flow rate at 10-15 mL / min;

[0040] S54: During the atomization process, ensure that the indoor temperature is maintained at 20-25 degrees Celsius and the relative humidity is 55-65%;

[0041] S55: The adobe bricks are atomized on each side in turn, with a 6-minute interval between each treatment to ensure that the adobe bricks fully absorb the mixed liquid.

[0042] Furthermore, in step S6, the ultrasonic treatment is performed at a frequency of 20-40 kHz for a duration of 10-30 minutes.

[0043] Furthermore, the step of using infrared light irradiation in step S7 specifically involves:

[0044] S71: Select an infrared emitter and set the intensity and wavelength of the infrared light to 890nm as the starting point;

[0045] S72: Adjust the position and angle of the infrared emitter according to the size and shape of the adobe brick to ensure that the surface of the adobe brick is uniformly irradiated with infrared light;

[0046] S73: Start infrared light irradiation and check the temperature and condition of the adobe every 30 minutes to ensure that it does not overheat or change color, and to ensure that there is no obvious drying or crystallization on the surface of the adobe.

[0047] S74: After the infrared irradiation ends, immediately move the adobe bricks to a well-ventilated place for cooling to prevent thermal stress caused by heat accumulation.

[0048] Furthermore, the secondary calcination step in step S7 specifically includes:

[0049] S71: First, place the clay bricks into the calcining furnace, ensuring that the distance between the clay bricks is at least 5 cm, so as to ensure that the heat is evenly distributed and that they do not stick together.

[0050] S72: Set the temperature rise rate of the calcining furnace to 15 degrees Celsius / minute until it reaches the preset 1300 degrees Celsius;

[0051] S73: After reaching the preset temperature, maintain this temperature and continue calcining for 2 hours;

[0052] S74: After the second calcination is completed, gradually reduce the temperature inside the furnace, and control the cooling rate at 8 degrees Celsius / minute until the temperature of the adobe bricks drops to room temperature;

[0053] S75: Remove the clay bricks from the calcining furnace and place them in a well-ventilated area for natural cooling for at least 12 hours to ensure that the clay bricks are completely cooled and their microstructure is stabilized.

[0054] Furthermore, the various elemental minerals include carbon, oxygen, hydrogen, nitrogen, potassium, sodium, calcium, magnesium, chlorine, sulfur, iron, iodine, copper, manganese, zinc, selenium, molybdenum, chromium, cobalt, nickel, fluorine, vanadium, and tin.

[0055] The beneficial effects of this invention are:

[0056] This invention extracts minerals containing a variety of trace elements from carefully selected raw ores. This process not only reduces dependence on single mineral resources, but also makes full use of the trace elements in the raw ores, enhancing resource utilization efficiency. Compared with traditional preparation methods, this process greatly reduces resource waste and environmental pollution.

[0057] This invention, through multi-stage processing steps including atomization, ultrasonic treatment, and infrared irradiation, ensures that trace elements penetrate deeply into the clay and form a tight bond with the ceramic. This not only improves the physical strength and durability of the ceramic but also endows it with special functional properties, such as the release of trace elements beneficial to the human body.

[0058] This invention enables the preparation of functional ceramics rich in trace elements. These ceramics have broad application prospects in many fields such as medicine, daily life, and art decoration. For example, when used as tableware, they can release trace elements that are beneficial to the human body into food. Attached Figure Description
