Description
Technical Field
[0001] The invention relates to the technical field of glass processing, and in particular to a processing technology for colored glass. Background Art
[0002] The application fields of colored glass are more extensive, including construction, automobile, decoration and other industries. With the improvement of people's living standards and the continuous changes in aesthetic concepts, the demand for colored glass is also increasing. It is not only required to have a beautiful appearance, but also to have good performance. In addition, the enhancement of environmental awareness has also prompted people to put forward higher requirements on the production process of colored glass, hoping to use more environmentally friendly materials and processes to reduce pollution to the environment.
[0003] With the development of the construction and decoration industries, the demand for colored glass is increasing. The traditional method of preparing colored glass has problems such as single color and poor durability. Magnetron sputtering coating technology, as an advanced surface treatment technology, can deposit various functional films on the glass surface, with the advantages of rich colors and stable performance. Summary of the invention
[0004] The technical problem to be solved by the present invention is to provide a processing technology for colored glass which is simple in construction, reliable in use, easy to clean, strong in anti-breakage ability and low in cost.
[0005] In order to solve the above technical problems, the present invention is solved by the following technical solutions: A processing technology of colored glass comprises the following steps: Step 1, glass substrate selection and cleaning: select a glass substrate of appropriate size and type according to specific needs, ensure that its surface is flat and has no obvious defects, clean the glass substrate, and use ultrasonic cleaning, deionized water and appropriate cleaning agents to remove oil, dust and other impurities on the glass surface. After cleaning, rinse with deionized water and dry; Step 2, target selection and installation: According to the required color and performance requirements of the colored glass, select the appropriate target material. Common target materials include metals, metal oxides, etc. Install the target material on the target holder of the magnetron sputtering equipment to ensure that it is firmly installed and accurately positioned; Step 3: Equipment inspection and debugging: Check various components of the magnetron sputtering equipment, including the vacuum system, power system, gas control system, etc., to ensure the normal operation of the equipment, debug the equipment, and set appropriate process parameters, such as sputtering power, gas flow, deposition time, etc.; Step 4: Vacuuming: Seal the vacuum chamber with the glass substrate and target installed, start the vacuum system, start vacuuming, and gradually reduce the pressure in the vacuum chamber to the required working vacuum degree, generally below 10⁻³Pa; Step 5, introducing inert gas: When the vacuum degree reaches the requirement, introduce inert gas, usually argon, into the vacuum chamber through the gas control system, and adjust the gas flow rate to keep the gas pressure in the vacuum chamber within a suitable range; Step 6: Generate plasma: Turn on the power system. Under the combined action of the electric field and the magnetic field, the argon gas is ionized into argon ions and electrons to form plasma. The electrons are bound near the target surface under the action of the magnetic field to form a high-density plasma region. Step 7, monitoring and adjustment: During the coating process, various monitoring equipment is used to monitor the coating thickness, color and other parameters in real time. According to the monitoring results, the process parameters such as sputtering power, gas flow, deposition time, etc. are adjusted in time to ensure that the coating quality meets the requirements; Step 8, annealing: After the coating is completed, the glass can be annealed. The glass is placed in an annealing furnace, heated and kept warm at a certain temperature, and then slowly cooled. Annealing can eliminate the stress generated during the coating process and improve the adhesion and stability of the film. Step 9, quality inspection: Conduct quality inspection on the coated colored glass, including appearance inspection, color uniformity inspection, film thickness measurement, adhesion test, etc., to ensure that the quality of the glass meets the relevant standards and requirements; Step 10. Packaging and storage: Pack qualified colored glass with appropriate packaging materials to prevent the glass from being damaged during transportation and storage.

[0056] The specific steps are as follows: the staff selects glass substrates of suitable specifications and good quality, ensures that there are no obvious scratches, cracks and other defects on the surface, cleans the glass substrate, and uses ultrasonic cleaning equipment, deionized water and appropriate cleaning agents to remove oil, dust and other impurities on the glass surface. After cleaning, rinse with deionized water and dry. The staff then selects the appropriate coating material according to the required color and performance requirements of the colored glass. Common coating materials include metal oxides, metal nitrides, etc. At this time, the staff selects appropriate magnetron sputtering coating equipment, including vacuum chamber, magnetron sputtering target, power supply, gas control system, etc., debugs the coating equipment, checks the operation of each component, and ensures the sealing of the vacuum system, the stability of the power supply and the gas The accuracy of the control system is controlled. The coating material is prepared into a target material using powder metallurgy, hot pressing and other methods. At the same time, the purity, density and size of the target material meet the requirements. The staff selects suitable magnetron sputtering coating equipment, including vacuum chamber, magnetron sputtering target, power supply, gas control system, etc., debugs the coating equipment, checks the operation of each component, ensures the sealing of the vacuum system, the stability of the power supply and the accuracy of the pneumatic control system. At this time, the staff carefully loads the pre-treated glass substrate into the vacuum chamber of the coating equipment, ensures that the glass substrate is placed stably and at a suitable distance from the target material, closes the vacuum chamber at the same time, starts the vacuum system, starts evacuating, and gradually reduces the pressure in the vacuum chamber to the required working vacuum degree, generally at 10⁻³Pa Next, when the vacuum degree reaches the requirement, an inert gas, usually argon, is introduced into the vacuum chamber through the gas control system, and the gas flow rate is adjusted to keep the air pressure in the vacuum chamber within an appropriate range. At this time, the staff turns on the power and starts the magnetron sputtering target. Under the combined action of the electric field and the magnetic field, the argon gas is ionized into argon ions. The argon ions hit the surface of the target material, causing the target material atoms to sputter out. The sputtered target material atoms collide with the gas molecules during flight, gradually lose kinetic energy, and are finally deposited on the surface of the glass substrate to form a thin film. The thickness, color and performance of the coating are controlled by adjusting parameters such as sputtering power, gas flow rate, and deposition time, and online monitoring equipment is used to monitor the coating process in real time so that timely adjustments can be made. Parameters, after coating is completed, the glass substrate is taken out of the vacuum chamber and annealed. The glass substrate is placed in an annealing furnace, heated and kept warm at a certain temperature, and then slowly cooled. Annealing can eliminate the stress generated during the coating process and improve the adhesion and stability of the film. The coated colored glass is quality inspected, including appearance inspection, color uniformity inspection, film thickness measurement, adhesion test, etc., to ensure that the quality of the glass meets the relevant standards and requirements. Finally, the staff packs the qualified colored glass and uses appropriate packaging materials to prevent the glass from being damaged during transportation and storage. The packaged glass is stored in a dry and ventilated environment to avoid direct sunlight and moisture.
