Description

Technical Field

[0001] The invention belongs to the technical field of stone product manufacturing technology, and involves key technologies such as boring processing, weight balance design, and firing process optimization of wooden fish stone materials; specifically, it relates to a method for making a thin-bodied wooden fish stone pot that can float on water. Background Art

[0002] In the current field of stoneware craft production technology, the manufacturing process of thin-bodied ceramic vessels is particularly complicated. In particular, for thin-bodied pots made of natural stone materials such as Muyu stone, there are several difficulties and problems:

[0003] First, material processing is difficult. Natural stones like Muyu stone are difficult to machine due to their high hardness. During the production process, effectively boring out a pot body with uniform wall thickness presents a technical challenge.

[0004] Secondly, there's the issue of controlling the pot's weight. The traditional stoneware manufacturing process often results in a heavy pot, which not only affects the feel during use but also negatively impacts portability. Therefore, how to reduce the pot's weight while ensuring its strength became a pressing issue.

[0005] Third, the balance between the capacity and weight of the kettle body. While reducing the weight of the kettle body, the capacity and stability of the kettle body must be guaranteed to avoid tilting or tilting during use.

[0006] Fourth, the stability problem during the firing process. During the high-temperature firing process, the density and hardness of the material will change, which has a significant impact on the final performance of the pot.

[0007] Finally, there is the issue of floating performance. Traditional ceramic kettles do not have the ability to float on water, which limits their application scope in specific occasions. In response to the above problems, the following is a description of some existing technologies:

[0008] In the prior art, the process of boring the wall of a wooden fish stone pot usually relies on manual operation and simple tools, such as a bore lead. However, due to the hardness of the wooden fish stone, it is difficult to ensure the thickness and uniformity of the boring.

[0009] Measuring tools can help improve boring accuracy, but manual errors still exist.

[0010] The design of the spout and handle often focuses on aesthetics and practicality, but rarely considers the overall balance of the pot body. During the firing process, although the density and hardness of the material can be improved by controlling the firing temperature and atmosphere, this process requires a high level of experience and skill from the firing worker.

[0011] From the above description of the background technology, it can be seen that the existing technology has shortcomings in material processing, weight control, balance design, firing stability and floating performance. The present invention aims to address these difficulties and provide a process for making a thin-bodied wooden fish stone pot that can float on water. Summary of the Invention

[0012] In view of this, the purpose of the present invention is to overcome the existing shortcomings and provide a method for making a thin-bodied wooden fish stone pot that can float on water. The method aims to overcome the defects in the existing wooden fish stone thin-bodied pot making technology, such as the difficulty in material processing, poor weight and balance of the pot body, difficulty in controlling the material properties after firing, and lack of floating performance. By controlling the thickness of the pot wall, designing the weight balance structure of the spout and the handle, and optimizing the firing process to reduce the density of the wooden fish stone and increase the hardness, the thin-bodied wooden fish stone pot can float on water, while achieving the effects of beautiful appearance, light use, large capacity, good air permeability, etc., thereby enhancing the product's market competitiveness and promoting technological progress in the stone handicraft manufacturing industry.

[0013] To achieve the above objectives, the present invention is implemented through the following technical solutions: A method for making a thin-bodied wooden fish stone pot capable of floating on water, characterized in that it comprises the following steps:

[0014] S1. Use a bore lead tool to bore the wooden fish stone raw material to form the basic shape of the pot body, pot lid and pot spout;

[0015] S2. When designing the spout, a spherical hole is reserved and the weight is increased while increasing the water output to balance the weight of the handle and ensure the balance of the pot body.

[0016] S3. Firing the hollowed-out wooden fish stone pot to reduce the density of the wooden fish stone and increase its hardness.

[0017] Furthermore, in step S1, a caliper is used to assist in measurement to control the thickness of the pot wall to 3 mm ± 0.5 mm and ensure that the thickness of the pot wall is uniform.

[0018] Furthermore, in step S2, a spherical hole is machined inside the spout, and the weight is adjusted by reserving the wall thickness of the spout so that the ratio of the total mass of the spout to the mass of the handle is 1:0.9-1.1.

[0019] Furthermore, in step S3, the firing temperature is controlled between 600-1000° C. and the firing time is 1-12 hours.

[0020] Furthermore, a gradient firing process is adopted:

[0021] The first stage: heating to 600-650℃ at a rate of 5-8℃ / min and keeping warm for 1-2h to decompose organic matter; the second stage: heating to 850-900℃ at a rate of 3-5℃ / min and keeping warm for 2-3h to complete crystal phase transformation; the third stage: heating to 950-1000℃ at a rate of 1-2℃ / min and keeping warm for 1-1.5h to achieve densification.

[0022] Furthermore, nitrogen protection is introduced during the second stage of firing, with a gas flow rate of 2-3 L / min and an oxygen content controlled at ≤0.5%.

[0023] Furthermore, after firing in step S3, the density of the wooden fish stone pot is reduced to 0.8-1.2 g / cm 3 , the hardness increases to Mohs hardness 5-7.

[0024] Furthermore, after firing in step S3, the air permeability of the wooden fish stone pot reaches a gas exchange rate of not less than 10 liters per square meter per hour.

[0025] Furthermore, after the fired wooden fish stone pot is naturally cooled to room temperature, it is cleaned, polished, and decorated to obtain a finished thin-bodied wooden fish stone pot.

[0026] The present invention has achieved significant results in many aspects at the technical level, not only solving the existing technical problems, but also having the following beneficial effects:

[0027] This method uses a bore lead tool for boring, supplemented by calipers for measurement. This allows for precise control of the wall thickness of the wooden fish stone pot to approximately 3mm (within a certain margin of error), significantly improving the uniformity of the pot wall thickness. Compared to traditional manual boring techniques, this effectively reduces thickness deviations, ensuring product precision and consistency, and ensuring that each thin-walled wooden fish stone pot is of more stable and reliable quality.

[0028] This invention achieves efficient material utilization. While reducing the weight of the stone pot, it also increases its capacity, avoiding material waste and improving material utilization efficiency. This means that with the same raw material input, more thin-bodied wooden fish stone pots with higher quality and larger capacity can be produced, thus increasing the utilization value of resources.

[0029] The reduced weight and increased capacity of this invention make the thin-bodied wooden fish stone teapot more convenient to use, making it easy to carry for everyday home use, outdoor activities, travel, and other occasions. Furthermore, the weight-balanced design of the spout and handle prevents the teapot from tilting during use, further improving its stability and comfort, and enhancing its practicality.

[0030] Thanks to precise wall design and optimized post-firing material properties, the thin-walled wooden fish stone teapot possesses the ability to float on water. This feature not only enhances the product's appeal and aesthetic appeal, but also expands its application scenarios, allowing it to be used in special occasions such as water-based tea ceremonies and landscape decorations, enhancing its craftsmanship and market appeal.

[0031] By optimizing the firing process and strictly controlling the firing temperature and atmosphere, this invention reduces the density of the wooden fish stone after firing, increases its hardness, and improves its breathability. The low density makes the teapot more buoyant, the high hardness enhances its durability, and the good breathability better preserves the flavor of the tea, improving the overall quality of the product.

[0075] Example 3

[0076] This embodiment provides a method for making a thin-walled wooden fish stone pot capable of floating on water, comprising the following steps:

[0077] (1) Raw material selection and pretreatment: The density is 2.3-2.5g / cm 3 2. The surface of the wooden fish stone raw material with Mohs hardness of 6.0-7.0 is cleaned and roughly processed into shape;

[0078] (2) Precision boring processing:

[0079] Use the bore lead tool to bore the pot body, and use the caliper to measure the pot wall thickness in real time;

[0080] Control the pot wall thickness to 3.0±0.3mm and ensure the wall thickness uniformity deviation is ≤5%;

[0084] (4) Gradient firing process:

[0085] The first stage: heating to 600-650℃ at a rate of 5-8℃ / min and keeping warm for 1-2h to decompose organic matter;

[0086] The second stage: heating to 850-900℃ at a rate of 3-5℃ / min and keeping at this temperature for 2-3h to complete the crystal phase transformation;

[0087] The third stage: heating to 950-1000℃ at a rate of 1-2℃ / min and keeping at this temperature for 1-1.5h to achieve densification;

[0088] (5) Post-processing and performance testing:

[0090] Perform a floating test to ensure that the kettle can float stably on the water surface for ≥8 hours.

[0091] Example 4

[0092] (1) Boring process optimization

[0093] To achieve a uniform wall thickness of 3mm in compliance with the standard for thin-walled wooden fish stone pots, a borer is used as the primary boring tool. Due to the high hardness of wooden fish stone, conventional tools struggle to guarantee accurate machining. The borer's unique design and material make it highly effective for boring wooden fish stone. Calipers play a crucial auxiliary measurement role in this boring process. With an accuracy of ±0.5mm, calipers are used to measure the wall thickness at regular intervals or at key processing points. Any deviations are immediately adjusted to ensure uniform wall thickness.

[0094] For example, when processing a batch of wooden fish stone pots, calipers with an accuracy of ±0.5mm were used to measure the pot wall thickness in real time. Boring began with the pot body, drilling the borehole at the predetermined location, then gradually expanding and trimming it. During this process, the caliper gauge revealed that the pot wall thickness was 0.3mm thinner than the standard at one point. The lead's penetration depth was immediately adjusted. After multiple measurements and fine-tuning, the wall thickness of this batch of pots was ultimately controlled between 2.5-3.5mm, achieving the desired effect of reducing weight while increasing capacity. This uniform thickness also laid the foundation for the subsequent buoyancy of the pot body.

[0095] By precisely controlling the wall thickness, a conventionally sized thin-walled wooden fish stone pot, for example, is approximately 20% lighter and 15% more capacious than a similar pot made with traditional techniques. Furthermore, the uniformly thin wall distributes the buoyancy of the pot more evenly in water, giving it a preliminary floating capability and significantly improving its overall performance and user experience.

[0096] (2) Weight balance design of the spout and handle

[0097] Adjust the weight to ensure balance by reserving wall thickness, instead of adding material, just reducing the original material;

[0098] In the design of the spout, a spherical hole structure is specially reserved, and the weight is adjusted by reducing the original material (reserved wall thickness). When determining the weight adjustment amount, the handle is weighed first, and according to the principle of moment balance,

[0099] Calculate the weight that needs to be adjusted for the spout, ensuring that the ratio of the total mass of the spout to the mass of the handle is maintained within the range of 1:0.9-1.1.

[0100] For example, if you're making a thin-walled wooden fish stone teapot of a specific size, and the handle is measured to weigh 100g, then based on the mass ratio range, the total mass of the spout after adjusting for weight should be between 90-110g. By adjusting the spout's wall thickness and weighing it, you can ultimately achieve an appropriate total spout mass, such as 105g.

[0101] In actual use, the kettle body, thanks to this weight-balanced design, maintains excellent balance no matter how much liquid is added, preventing the spout from tilting or the kettle body from tilting due to uneven weight. This significantly improves the user experience, making operation more comfortable and greatly enhancing the stability of the kettle body.

[0102] (3) Firing process optimization

[0103] The thin-bodied Muyu stone pot is fired using a gradient firing process and strictly controlled atmosphere. After the pot is hollowed and weight-balanced, it is placed in the kiln. In the first stage, the temperature is raised at a rate of 5-8°C / min to 600-650°C and held at that temperature for 1-2 hours. This allows the organic matter within the Muyu stone to fully decompose, preventing any residual organic matter from affecting the stone's properties during subsequent firing.

[0104] Next, the temperature is raised to 850-900°C at a rate of 3-5°C / min and held at that temperature for 2-3 hours. During this stage, nitrogen protection is introduced, with the gas flow rate controlled at 2-3L / min and the oxygen content controlled at ≤0.5%. Crystallization phase transformation is completed under the nitrogen protective atmosphere, preventing the beneficial components in the wooden fish stone from being oxidized and ensuring the firing quality.

[0105] Finally, the temperature is raised to 950-1000°C at a rate of 1-2°C / min and kept at this temperature for 1-1.5h to achieve densification.

[0106] After such a firing process, taking a set of experimental data as an example, the density of the wooden fish stone pot after firing is about 1.5g / cm 3 Reduced to 0.8-1.2g / cm 3 The hardness has increased from 4-5 on the Mohs scale to 5-7, and the air permeability has reached a minimum of 10 liters of gas exchange per square meter per hour. The reduced density makes the teapot more buoyant in water, the increased hardness improves its durability, and the good air permeability helps preserve the flavor of the tea, significantly improving the overall quality and market appeal of the product.

[0107] (4) Utilization of floating performance

[0108] The thin-walled wooden fish stone pot made with the above optimized process can float naturally on the water. Due to the uniform and thin thickness of the pot wall and the reduced density after firing, the pot body appears to float stably on the water surface.

[0109] From the appearance, its unique floating posture combined with the texture of the wooden fish stone itself makes the pot more ornamental and becomes an exquisite handicraft.

[0110] In actual use, the floating thin-walled wooden fish stone pot is even lighter. Its lightness is demonstrated by its floating nature, enhancing the user experience. These combined advantages significantly improve the product's craftsmanship and market appeal, providing consumers with a superior, unique user experience.

[0111] (5) Description of the difference between the technical means and the prior art

[0112] Compared with the existing technology, the present invention has achieved a qualitative leap in the boring process. The existing technology relies on manual operation and simple tools, resulting in large errors in the thickness of the pot wall and difficult to accurately control. However, the present invention uses a bore lead and high-precision calipers to accurately control the thickness of the pot wall within an extremely small error range, ensuring the uniformity of the pot wall and the stability of the pot body structure. For example, when comparing 100 pots made using the process of the present invention with 100 pots made using traditional methods, the proportion of pot wall thickness errors within ±0.5mm in the pots made using the present invention reached 95%, while the proportion of pots made using traditional methods was only 30%.

[0113] Existing technologies rarely consider the weight balance between the spout and handle, resulting in poor kettle stability. The present invention utilizes the principle of moment balance for precise design and weight adjustment, significantly improving kettle stability, a feat unmatched by existing technologies. In actual use tests, a kettle made using the present invention remained balanced even when filled with water and placed on a surface tilted at 15°, whereas a kettle made using traditional techniques would tip over at a tilt angle of 5°.

[0114] Existing firing techniques lack precision and systematic control over temperature and atmosphere, making it difficult to optimize material properties. The present invention's gradient firing process and nitrogen protection, based on thermodynamics and materials science principles, precisely control firing conditions, effectively improving material properties and enhancing overall product performance, a feat unattainable with conventional firing methods.

[0115] (6) Scientific principles

[0116] The optimization of the boring process uses the principles of material mechanics and geometry. From the perspective of material mechanics, precise control of the thickness of the kettle wall can reduce the weight while ensuring the strength of the kettle body. For example, according to the compressive and bending strength characteristics of the material, a kettle wall thickness of 3mm can meet the strength requirements and minimize the weight.

[0117] From a geometric perspective, the pot's capacity is increased through precise size and shape control and the rational distribution of materials. For example, when designing the pot's body, specific curves and radians are used to maximize capacity within a limited space.

[0118] The weight balance of the spout and handle is designed based on the principle of torque balance. According to the principle of leverage, force multiplied by the lever arm equals torque. By adjusting the weight of the spout and handle, as well as their distance from the fulcrum of the kettle body, the torque generated by the spout and handle is equal, ensuring the kettle body remains balanced during use and preventing the spout from tilting.

[0119] Firing process optimization is based on the principles of thermodynamics and materials science. From a thermodynamic perspective, controlling the heating rate and holding time at different stages provides the appropriate energy conditions for the physical and chemical reactions within the wooden fish stone. For example, during the organic matter decomposition stage, appropriate temperature and time ensure full decomposition; during the crystal phase transformation stage, precise temperature control promotes a change in the crystal structure that improves material performance. From a materials science perspective, a nitrogen protective atmosphere prevents oxidation of the material at high temperatures, maintaining the stability of its chemical composition. This in turn improves the material's physical properties, such as density, hardness, and permeability, enhancing the product's overall performance and market appeal.

[0120] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
