Description

Technical Field

[0001] The invention specifically relates to a deep processing engraving and polishing process for high borosilicate glass materials. Background Art

[0002] At present, it is common to see some glassware with engraved decorations on the surface in the market. Some patterns are more complex, while others are relatively simple. In fact, engraved glassware can be roughly divided into two categories according to its processing technology and effect: grass engraving (shallow engraving) and edge engraving (deep engraving). Both are hand-engraved to meet the requirements of the design graphics. The materials used for hand-engraving are also different, such as K9 material, crystal material, high white material, general high material, etc., but these materials are all made of soda-lime glass. There are no products produced by deep processing engraving and polishing technology of high borosilicate glass on the market.

[0003] With the development of glass bottle production technology, customers' demand for rich product appearance is increasing, and deep processing of glass products is becoming more and more popular with customers. As a special glass material, high borosilicate glass has many unique physical and chemical properties. High borosilicate glass is made of high-quality raw materials, so its transparency is very high, and it is also wear-resistant, smooth, easy to clean, and hygienic. High borosilicate glass has good heat resistance. After simple preheating, it can be directly processed by high-temperature hot melt and can be shaped arbitrarily. This kind of glass has strong adaptability to temperature changes and can withstand the temperature difference from freezing to high temperature. It is suitable for microwave heating and direct contact with open flames. It is not easy to burst and has good safety performance. High borosilicate glass processed into double-layer insulated water cups not only has good thermal insulation performance, but also is not hot and safer to use. Its hygienic performance meets food grade standards, can hold hot water and other high-temperature liquids, is erosion-resistant, wear-resistant, has no odor or cross-flavor. And it has good chemical stability. High borosilicate glass has a wide range of applications: it can be used for glass products, microwave supplies, solar tubes, chemical reaction containers and many other purposes.

[0004] Due to its special manufacturing process and materials, high borosilicate glass products are harder than ordinary glass. In addition, the special processing technology of hot-melt molding makes the product have large internal and external stress deviation and hard material, which is not conducive to deep processing and decorative production. The industry often uses superficial processing such as labeling, gold drawing, and painting to decorate products. At present, there is no deep processing engraving and polishing process for high borosilicate products in the industry. Summary of the invention

[0006] In order to achieve the above requirements, the technical solution adopted by the present invention is: to provide a high borosilicate glass material deep processing engraving and polishing process, the high borosilicate glass material deep processing engraving and polishing process comprises the following steps: S1: annealing to eliminate stress, using a 6-temperature zone furnace, setting the temperature to 350°C in zone 1, 480°C in zone 2, 560°C in zone 3, 580°C in zone 4, 580°C in zone 5, and 540°C in zone 6; S2: deep processing engraving and polishing, using a 150 / 50m / s grinding wheel, and adjusting the speed to 400-500 rpm, Use drip cooling with a dripping speed of 100-120 drops / min; S3: Polishing, prepare the polishing liquid in the ratio of 1:1.2 for white light polishing liquid and 1:1.5 for red light polishing liquid, first perform white light polishing on the semi-finished product with engraving until it is transparent, and then perform red light polishing until the engraved part is crystal clear; S4: Annealing to eliminate secondary stress, use a 6-temperature zone oven, set the temperature to 350℃ for zone one, 480℃ for zone two, 560℃ for zone three, 560℃ for zone four, 560℃ for zone five, and 520℃ for zone six.

[0007] Preferably, step S2 also includes: drawing a pattern on a borosilicate glass tube, a water cup, or other products of similar thickness in advance, and then engraving the pattern into shape according to the required operation.

[0008] Preferably, step S3 further comprises cleaning the polished product and drying it for later use.

[0009] Preferably, the mesh speed of the 6-temperature zone oven is adjusted between 16 and 12 according to the thickness.

[0014] For the sake of simplicity, certain technical features well known to those skilled in the art are omitted in the following description.

[0015] According to one embodiment of the present application, the deep processing engraving and polishing process of the high borosilicate glass material uses high borosilicate glass materials with a thickness of 3mm-10mm, water cups, or other high borosilicate glass products of similar thickness. The important processes are operated according to the following steps: ① Annealing to eliminate stress, use a multi-temperature zone annealing furnace or a baking furnace, the inventor uses a 6-temperature zone oven, set the temperature to 350℃ for zone 1, 480℃ for zone 2, 560℃ for zone 3, 580℃ for zone 4, 580℃ for zone 5, and 540℃ for zone 6, and the net speed is adjusted to 16-12 according to the thickness (calculated as 3.5-5 hours according to time). ② Deep processing engraving and polishing process, use a 150 / 50m / s grinding wheel, adjust the speed to 400-500 rpm (note that the speed should not be too fast), use drip cooling, and the drip speed is 100-120 drops / min. Draw the desired pattern on the high borosilicate glass tube, water cup, or other products of similar thickness in advance, and the craftsman technicians will engrave the pattern according to the requirements. ③ Polishing: Prepare the polishing liquid in the ratio of 1:1.2 for white light polishing liquid and 1:1.5 for red light polishing liquid. Polish the semi-finished product with white light first until it is transparent, and then polish it with red light until the engraved part is crystal clear. Clean the polished product and dry it for later use. ④ Annealing to eliminate secondary stress: Use a 6-zone oven with set temperatures of 350℃ for zone 1, 480℃ for zone 2, 560℃ for zone 3, 560℃ for zone 4, 560℃ for zone 5, and 520℃ for zone 6. Adjust the screen speed by 16-12 according to the thickness (calculated as 3.5-5 hours according to time). After annealing, the production steps are completed.

[0016] According to one embodiment of the present application, the deep processing engraving and polishing process of high borosilicate glass material focuses on solving the problem that high borosilicate glass cannot be deep processed, engraved and polished. An innovative and operational and batch-based deep processing engraving and polishing process of high borosilicate material is developed to provide customers with a rich product appearance experience and also provide expansion space for the deep processing of high borosilicate products.

[0017] According to one embodiment of the present application, the first annealing of the deep processing engraving and polishing process of the high borosilicate glass material is to solve the stress of the high borosilicate glass product during the front end molding. After the grinding and engraving operation, the surface is damaged and the external structure changes, and secondary stress is regenerated. The secondary annealing is mainly to eliminate the secondary stress.

[0018] The above-mentioned embodiments only represent several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention.
