Description

Technical Field

[0001] This invention relates to the field of brick blanks, and in particular to a brick blank formula and production process for a machine-made hand-laid gold brick. Background Technology

[0002] Brick blanks, as a traditional building material, have a long history and unique artistic and ecological value. However, with the increasing demands of the modern construction industry for environmental protection, personalization and functionality, traditional craftsmanship faces challenges in terms of resource efficiency, energy consumption control and artistic expression.

[0003] However, in brick production, traditional brick making relies on clay raw materials and high-temperature firing processes. Although this can ensure the density of the brick body, it has the problems of high energy consumption and low resource utilization. Although hand-pressing gives the brick body a unique texture, the yield is limited by factors such as drying cracking and uneven stress. At the same time, hand-made brick making is slow and cannot meet the personalized and usage requirements of modern decorative building materials. Furthermore, although modern brick and tile production has improved efficiency through waste recycling, standardized production has weakened the artistry of the brick body, and excessive addition of waste may affect the strength of the body. Although low-temperature firing and other technologies reduce energy consumption, they cannot take into account both the mechanical properties and aesthetics of the brick body. Summary of the Invention

[0004] The main objective of this invention is to provide a brick blank formula and production process for machine-made hand-paved gold bricks, which can effectively solve the technical problems raised in the background art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A brick blank formula for a machine-made handmade paving brick includes the following components in parts by weight: 40-60 parts clay, 20-30 parts water, 5-10 parts plant fiber, and 5-15 parts natural mineral additives.

[0007] Preferably, the plant fiber is rice straw fiber or bamboo fiber, and the fiber length is 1-5 mm.

[0008] Preferably, the natural mineral additive is rare earth pumice or nano silicon carbide with a particle size of less than or equal to 3 mm.

[0009] Preferably, the components further include 5-10 parts of waste material and 2-5 parts of humus soil.

[0010] A production process for a brick blank formula of handmade gold-colored floor tiles, the method specifically includes the following steps:

[0011] Step 1: Raw material pretreatment, the formula according to any one of claims 1-4 is mixed evenly using a centrifugal mixer to form mud blocks;

[0012] Step 2: Press the mud blocks with a machine. Use a press to press the mud blocks.

[0013] Step 3: Machine pressing and shaping. The brick blanks are pressed at room temperature using custom molds, and the surface of the molds is engraved with handmade patterns.

[0014] Step 4: Air dry naturally in the shade for 5 months;

[0015] Step 5: Firing and shaping, firing at 700-900℃ for 70 days;

[0016] Water injection: After the brick blanks are fired to maturity, water is injected into the kiln to cool them down, allowing the bricks to cool steadily from a high temperature and changing the color of the bricks from red during firing to bluish-gray.

[0017] Preferably, the specific operations of machine pressing and forming in step four include:

[0018] The hydraulic brick press uses custom-made molds, which are made of iron.

[0019] The hydraulic brick press maintains a pressing pressure within the range of 1.5-2 MPa, and the pressure is adjusted according to the thickness of the brick blank.

[0020] The pressing time is 30-60 seconds, and an intermittent pressing method is used, with 10 seconds of pressure applied and 5 seconds of pause, repeated 3-5 times to enhance the density of the brick blank and prevent cracking.

[0021] Preferably, the optimized conditions for natural air drying in step two include:

[0022] The relative humidity is controlled at 50%-70%, the temperature is maintained within the range of 15-30℃, and the drying time is 5 months, which is dynamically adjusted according to the ambient humidity: the drying time is extended when the air humidity is higher than 70%, and the drying time is shortened when the air humidity is lower than 50%.

[0023] Regularly turn and repair the bricks, turning them over once a day depending on the dryness of the brick surface. When turning them over, rotate the bricks 180 degrees with the machine to ensure even drying.

[0024] The drying area uses natural ventilation channels with a wind speed not exceeding 1m / s to prevent cracking on the surface of the brick blanks.

[0025] Preferably, the specific implementation of the scrap recycling step includes:

[0026] The scraps come from waste materials during the pressing and firing process. Before recycling, they are filtered and sorted by machine to remove impurities, and then crushed into particles with a particle size of less than 3mm.

[0027] The recycling rate is over 100%. The crushed scraps are mixed back into the new raw materials at a weight ratio of 5-15%. During mixing, a centrifugal mixer is used to ensure uniformity.

[0028] The recycling process is equipped with environmental protection measures, such as dust collection devices, to reduce pollution, and the recycling rate is recorded for quality traceability.

[0029] The beneficial effects achievable by the above embodiments of the present invention include: the introduction of waste bricks and humus into the formula, combined with the scrap recycling step, significantly reduces waste emissions and environmental impact, conforming to the concept of circular economy; the use of plant fibers as reinforcing agents, which are widely available and biodegradable, reduces dependence on non-renewable resources and enhances the eco-friendliness of brick blanks; and the use of a low-temperature firing process of 700-900℃, compared with traditional high-temperature firing, reduces energy consumption by more than 30%, reduces carbon emissions, and avoids additional energy consumption through natural drying.

[0030] In the machine pressing and molding process, the surface of the customized mold is engraved with textured patterns with a depth of 0.5-2.0mm. The machine processing method makes each brick blank have handmade textures, which saves the trouble of making bricks by hand. It is suitable for the field of high-end decorative building materials. At the same time, the machine replaces manual labor, improves production efficiency, reduces labor intensity, and completely achieves the effect of handmade bricks.

[0031] The synergistic effect of plant fibers and natural mineral additives improves the flexural strength and toughness of the brick blanks, reduces the breakage rate during transportation and use, and the centrifugal mixing and intermittent pressurization method forms uniform micropores. The brick blanks have moderate density and good heat insulation and sound insulation properties. During the natural drying process, the relative humidity is controlled and the brick blanks are turned over regularly to avoid surface cracking. The brick blanks have uniform moisture content, low internal stress after firing, and the yield rate is increased by more than 95%.

[0032] Scrap material recycling and manual operation reduce equipment investment, simplify the production process, reduce the labor intensity of workers, and are suitable for small-scale workshops or personalized customization. They also reduce production costs, use natural raw materials, have no chemical additives, and produce brick blanks with VOC emissions close to zero, making them suitable for interior decoration and ensuring user health.
