Description

Technical Field

[0001] The invention relates to the technical field of diamond synthesis, in particular to a drying device and a preparation method for diamond group abrasives. Background Art

[0002] Hard and brittle materials are prone to fracture during processing and have no significant deformation, such as ceramics, optical glass, quartz glass, sapphire and stone. Such materials have the advantages of high hardness, low thermal expansion coefficient and stable chemical properties, and are widely used in aerospace, defense equipment, optics, semiconductors and integrated circuits. Such materials are generally processed by plane grinders and diamond grinding. If single crystal diamond is used to process hard and brittle materials, the single crystal blade of the single crystal diamond is particularly easy to passivate, or the whole single crystal diamond falls off, resulting in a rapid decrease in grinding rate. The repair plate with a tooth plate or oilstone needs to be repaired at least to the thickness of the size of the single crystal particles to guide the new single crystal particles to leak out. The repair time is too long, the efficiency is low, and the grinding effect cannot be guaranteed; Diamond abrasives are widely used in the field of semiconductor material processing due to their high hardness, wear resistance and excellent grinding performance. In the preparation process of diamond abrasives, the drying process has an important influence on the quality and performance of the final product. The traditional drying methods of diamond group abrasives are mainly through hot air drying (this method is simple and easy, but it may take a long time to achieve the ideal drying effect), vacuum drying (this method requires special vacuum equipment and high cost), microwave drying (this method may be limited in applicability to diamond abrasives because diamond is an electrical insulator and has a weak ability to absorb microwaves) and natural air drying (this method is greatly affected by weather and environmental conditions, the drying effect is unstable and time-consuming), these methods have the problems of low efficiency, high energy consumption, and easy cracking. Therefore, in view of the above situation, it is urgent to develop a drying device and preparation method for diamond group abrasive preparation to overcome the shortcomings in current practical applications.

[0027] Example 3 Based on Example 1-2, a method for preparing a diamond cluster abrasive comprises: Raw material mixing: according to the weight percentage, mix 25-45% of 30-60 micron diamond particles, 25-45% of ceramic binder and 30-50% of UV resin in a blender, stir well to form a uniform mixture; Molding: Use a scraper 40 to scrape the mixture into the concave placement block 7 of a preset shape, ensuring that the mixture fills the concave placement block 7 and levels the surface; Instant drying: Place the concave placement block 7 containing the mixture on the belt conveyor assembly 1 (and set the conveyor belt speed to 10m / min), and transport it to the drying box 3, adjust the UV lamp 5 to an appropriate intensity (40-80%), so that the mixture is instantaneously dried under UV light to form diamond cluster particles with a concave cavity shape; Adding and mixing buffer powder: Add 20-80% buffer powder (such as alumina, silicon carbide, etc.) to the dried diamond cluster particles and stir evenly again to improve the toughness and wear resistance of the abrasive; Sintering: Place the mixed materials in a muffle furnace and sinter at 650-700℃ for 3 hours to form a firm bond between the ceramic binder, diamond particles and buffer powder; Post-processing: After sintering, the product is taken out and sieved and cleaned to remove impurities and unsintered materials to obtain the final diamond group abrasive.

[0028] The beneficial effects of the above technical solution are: 1. Efficient mixing and molding: By precisely controlling the ratio of the raw materials and fully mixing them in the agitator, the uniform distribution of the diamond particles, the ceramic binder and the UV resin is ensured, which provides a good foundation for subsequent molding. During the molding process, a scraper 40 is used to accurately scrape the mixture into the concave placement block 7 of a preset shape, which not only ensures the accuracy of the shape, but also improves the production efficiency.

[0029] 2. Instant drying technology: Using UV lamp 5 at appropriate intensity to instantaneously dry the mixture not only greatly shortens the drying time, but also avoids the thermal stress problem that may be caused by traditional drying methods, protects the integrity and performance of the diamond particles, and at the same time, UV drying technology can also promote the curing of the resin to a certain extent and enhance the initial strength of the material.

[0030] 3. Performance optimization: Adding buffer powder (such as aluminum oxide, silicon carbide, etc.) to the dried diamond cluster particles and stirring them evenly again effectively improves the toughness and wear resistance of the abrasive. The addition of buffer powder can absorb and disperse the impact force and heat generated during the grinding process, extend the service life of the abrasive, and improve grinding efficiency and processing quality.

[0031] 4. Strong bonding: During the high-temperature sintering process, a strong chemical and physical bond is formed between the ceramic binder and the diamond particles and buffer powder. This bond not only enhances the overall strength of the abrasive, but also ensures the stability and durability of the diamond particles during the grinding process, reducing the risk of falling off and breaking.

[0032] 5. Post-cleaning treatment: After sintering, impurities and unsintered materials are removed by screening and cleaning to ensure the purity and consistency of the product. This step is crucial to improving the processing performance of the abrasive and extending its service life.

[0033] 6. Environmental protection and energy saving: The entire preparation process is relatively environmentally friendly. UV drying technology reduces energy consumption and emissions. Although the high-temperature sintering process requires a certain amount of energy, it can achieve high efficiency and energy saving by precisely controlling the temperature and time. In addition, the raw materials used are mostly inorganic materials, which are easy to recycle and process.
