Description

Technical Field

[0001] This invention specifically relates to a production process that combines high borosilicate solid wrapping material with color mixing and hollow products. Background Technology

[0002] With the development of glass bottle manufacturing technology, customers' demands for diverse and high-end product appearances are constantly increasing. High borosilicate glass, as a special glass material, offers more possibilities for product appearance due to its unique secondary hot-melt plasticity and heat-resistant processing characteristics, providing more creative space for master craftsmen. Previously, color mixing processes were mostly achieved through raw material mixing and firing, and then layering colors using a blown fabric. Combining solid multi-color mixing with hollow products was particularly difficult due to the different expansion coefficients of various colorants and transparent materials, as well as the different thicknesses of the solid and hollow components.

[0021] To make the objectives, technical solutions and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments.

[0022] In the following description, references to "an embodiment," "an embodiment," "an example," "example," etc., indicate that the described embodiment or example may include a particular feature, structure, characteristic, property, element, or limitation, but not every embodiment or example necessarily includes that particular feature, structure, characteristic, property, element, or limitation. Furthermore, the repeated use of the phrase "an embodiment according to this application," while possibly referring to the same embodiment, does not necessarily refer to the same embodiment.

[0023] For simplicity, certain technical features known to those skilled in the art are omitted in the following description.

[0024] According to one embodiment of this application, a production process combining high borosilicate solid wrapping material color mixing with hollow products is provided, such as... Figure 1 As shown, it includes the following steps:

[0025] Step 1: Material selection. Choose suitable white or colored glass rods and conduct color matching experiments by trying different proportions of raw materials to ensure that the final color combination meets the product color matching requirements.

[0026] Step 2: Cleaning. The selected glass rod raw materials are cleaned using methods such as pure water, alcohol, and lactic acid, and then dried before use.

[0027] Step 3: Preheating. Preheat the high borosilicate transparent glass rod and the high borosilicate color glass rod in a low-temperature flame to a temperature of about 500°C (it is best if the glass rod turns orange-red) to avoid cracking during operation.

[0028] Step 4: Wrapping with Colorant 1: Firing and fusing the preheated transparent borosilicate glass rod with the colored glass rod 1 (the firing flame should be low, the blowtorch temperature should be approximately 850℃, and the glass rod should be slightly soft and orange-red); Wrapping with Colorant 2: Continuing to fire and fuse the preheated transparent borosilicate glass rod with the colored glass rod 2 (the firing flame should be low, the blowtorch temperature should be approximately 850℃, and the glass rod should be slightly soft and orange-red); This process can be repeated to fuse N different colorants.

[0029] Step 5: Impurity Removal. After the glass rod is coated with color, the mixture is continuously heated and fused using a medium flame (blowtorch temperature of about 1200℃). The reaction of the mixture is continuously monitored, and internal impurities and air bubbles are removed in a timely manner by pulling, clamping, or other methods.

[0030] Step Six: Melting. The purified mixture is heated with a high-temperature flame (the blowtorch temperature needs to be about 1500℃, and the gas pressure ratio should be based on the complete combustion of the gas) to fully melt the different color pigments.

[0031] Step 7: Molding. According to the product process requirements, the heated and fused composite glass rod is fired, pre-shaped, and then die-cast.

[0032] Step 8: Annealing. Place the die-cast product on a baking tray for annealing. The annealing temperature should be controlled between 500℃ and 600℃, depending on the product shape, to eliminate internal stress.

[0033] Step 9: Cleaning. Immerse the annealed product in a 5% hydrofluoric acid solution for 2 hours to remove surface impurities. After rinsing, rinse the product three times and let it air dry for later use.

[0034] Step 10: Polishing and Annealing: Place the cleaned product on a baking tray and preheat it at 300-400℃ for 5 minutes. After removing it, use a single-hole burner to adjust it to a blue flame state with the flame height of about 15cm to polish it and remove surface defects.

[0035] Step Eleven: Combining solid and hollow winding techniques:

[0036] 1. Wear protective gloves, sleeves, goggles and other personal protective equipment before handling fire.

[0037] 2. Check that the lamp holder, hose, and valve are in good working order. Identify the natural gas, oxygen, and main energy-consuming equipment and facilities. Use a 32-hole + single-eye lamp holder and prepare a lint-free cloth.

[0038] 3. Clean the mating products with a lint-free cloth to ensure that the surface is free of dust. For stubborn dirt that cannot be cleaned, wipe with a lint-free cloth dampened with alcohol. For severe cases, grinding or heating the clamping material can be used.

[0039] 4. Place the hollow and solid parts on a baking tray and preheat the oven to a low flame. The flame height should be higher than the highest point of the product. The preheating time should be no less than 2 minutes.

[0040] 5. Fire the preheated hollow and solid contact surfaces, remove the surface waste, and then use a clean carbon plate to flatten the contact surfaces and edges.

[0041] 6. Remove the two preheated materials and fire the corresponding joints simultaneously. During firing, fire both the hollow and solid joints at the same time. When both the hollow and solid joints turn orange-red, blow air into the hollow until the joint slightly bulges. Align the joints and align them, adjusting the direction and position. Once confirmed, immediately blow air into the solid area to adjust the concave part for shaping, positioning, and stretching until the position meets the desired requirements.

[0042] 8. Close the 32-hole lamp head, light the single-hole lamp head, and perform firing, fusion, leveling, and polishing at the joint. During the firing process, adjust according to the joint contour. For concave areas, blow air or use a special tweezer to press and shape them. If bubbles, black spots, or impurities appear at the joint, the defective points should be softened by heating and removed using pointed tweezers.

[0043] 9. After the area around the contact point is fired and polished, ignite the 32-hole lamp head, adjust the oxygen pressure appropriately, and use the flame to perform large-area uniform firing and annealing around the contact point. The best annealing standard is that the surface of the flame-fired part turns slightly red.

[0044] 10. Place the assembled product on a baking tray for annealing. The flame height should be 5-10cm above the highest point of the product, and the annealing time should not be less than 3 minutes.

[0045] According to one embodiment of this application, the combination of the high borosilicate glass two-color wrapping process with hollow products is an innovative glass deep processing technology. By pre-firing and wrapping glass rods of different colors, and then firing and shaping them at high temperature, high borosilicate glass colored craft products with composite colors are formed. Combining it with hollow products makes the products not only aesthetically pleasing but also functional.

[0046] According to one embodiment of this application, the production process of combining solid borosilicate glass with hollow products solves the fusion problem caused by the difference in the expansion coefficients of different colored borosilicate glasses by adjusting the material production process. At the same time, the hollow and solid processes are used to fuse the products to form high borosilicate glass colored products with composite colors. The combination with hollow products makes the products not only aesthetically pleasing but also functional.

[0047] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
