Description

Technical Field

[0001] This invention relates to the field of cleaning microcrystalline glass, and in particular to a cleaning agent for microcrystalline etched glass and a cleaning method using the cleaning agent. Background Technology

[0002] Etching is performed on the surface of microcrystalline glass to create a frosted texture, which is then used in various kitchen appliances, such as the front of induction cookers and ceramic cooktops. When used on the front of induction cookers or ceramic cooktops, the high-temperature resistance of the microcrystalline etched glass is required. Generally, decorative underlayer inks of different colors with medium to high temperatures are printed on the back of the microcrystalline etched glass, and a high-temperature resistant and easy-to-clean coating is sprayed on the front.

[0003] The surface of microcrystalline etched glass, obtained through etching, exhibits an uneven structure. After medium-temperature screen printing, this structure becomes contaminated with screen printing solvent oil and stubborn silicone oil. These contaminants adhere to the surface of the microcrystalline etched glass, forming a hydrophobic film. This hydrophobic film is extremely stubborn on the uneven surface of the microcrystalline etched glass and is very difficult to clean even with flatbed or ultrasonic cleaners. However, if this hydrophobic film is not thoroughly removed, it will severely affect the effectiveness of subsequent processing techniques such as nano-coating, film deposition, and secondary screen printing. Furthermore, insufficient coating adhesion can lead to coating peeling during use, failing to meet customer requirements.

[0004] The aforementioned deficiencies are what those skilled in the art would like to overcome. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned defects in the prior art. The first aspect of this invention provides a cleaning agent for microcrystalline etched glass.

[0006] Based on the first aspect of the present invention, the second aspect of the present invention also provides a cleaning method using the cleaning agent.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A cleaning agent for microcrystalline etched glass, comprising the following components in parts by weight:

[0009]

[0010] Furthermore, the surfactant is selected from any one of cocoyl glucoside, lauryl glucoside, and cetearyl glucoside.

[0011] A cleaning method using a cleaning agent for microcrystalline etched glass as described above includes the following steps:

[0012] Step S1, Inspection and Basket Loading of Microcrystalline Etched Glass:

[0013] Inspect the microcrystalline etched glass after screen printing and fix it in a basket;

[0014] Step S2, Preparation of cleaning agent for microcrystalline etched glass:

[0015] Take the prescribed amount of deionized water into a container, heat it, and then add the prescribed amounts of sodium carbonate, sodium polyphosphate, sodium silicate, surfactant, penetrant, wetting agent (3 parts) and complexing agent. Stir well to obtain a cleaning agent for microcrystalline etched glass.

[0016] Step S3, Ultrasonic Immersion Treatment:

[0017] Pour the cleaning agent for microcrystalline etched glass prepared in step S2 into the liquid tank. Take the microcrystalline etched glass that has been fixed in the basket in step S1 and immerse it in the cleaning agent for microcrystalline etched glass for ultrasonic immersion cleaning. Then use clean water to rinse the surface of the microcrystalline etched glass under high pressure. After the high pressure rinsing is completed, place the microcrystalline etched glass in a clean water tank so that the surface of the microcrystalline etched glass is in an immersion and moisturizing state.

[0018] Step S4: Surface polishing and cleaning treatment:

[0019] The surface of the microcrystalline etched glass is polished and cleaned to remove stubborn stains.

[0020] Step S5: High-pressure spray roller brush cleaning treatment:

[0021] Place the etched surface of the microcrystalline etched glass upwards. After surface polishing and cleaning, the microcrystalline etched glass is subjected to high-pressure spraying and roller brush treatment. After completion, the microcrystalline etched glass is removed.

[0022] Furthermore, in step S1, the basket is made by welding acid-resistant PP components.

[0023] Furthermore, in step S2, the deionized water in the container is heated to 70°C to 90°C; after the remaining components are added to the container, the stirring speed is 600 rpm to 800 rpm.

[0024] Furthermore, in step S3, the glass is automatically hoisted using a glass hoisting device. The horizontal cylinder of the glass hoisting device is activated, and the basket is moved within the slide rail by a robotic arm, thereby immersing the microcrystalline etched glass in a cleaning agent for microcrystalline etched glass.

[0025] Furthermore, in step S3, the temperature of the cleaning agent used for microcrystalline etched glass is 70°C to 80°C.

[0026] Preferably, in step S3, the amount of cleaning agent used for microcrystalline etched glass is replenished every four hours at a rate of 5% to 8%.

[0027] Furthermore, in step S3, the microcrystalline etched glass is immersed in a cleaning agent for microcrystalline etched glass, and the ultrasonic immersion cleaning time is 20 min to 25 min.

[0028] Preferably, in step S3, the ultrasonic power during ultrasonic immersion cleaning is 28K.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] 1. This invention provides a cleaning agent for microcrystalline etched glass and a cleaning method using the above-mentioned cleaning agent, which can effectively clean the hydrophobic film layer adhering to the surface of microcrystalline etched glass, with good cleaning effect; it is beneficial for subsequent processing of microcrystalline etched glass such as secondary screen printing process, resulting in high product yield, reducing the phenomenon of coating peeling off during use due to insufficient coating adhesion, and providing a good user experience.

[0031] 2. By using a glass hoisting device to automatically hoist the glass, the basket containing the microcrystalline etched glass is completely immersed in a cleaning agent for microcrystalline etched glass. The automated operation through robotic arms and programs helps stabilize process parameters in the process flow, saves time for manual handling, ensures the safety of workers, and improves work efficiency.
