The processing and manufacturing process of frosted glass mainly includes the following steps:
1. Preliminary Preparation
Designing the base draft: Use a computer to design the required patterns or designs, which is the first step in making frosted glass. For small formats, a laser printer can be used to output the film, while for large formats, a computer engraving machine can engrave on black instant stickers or use a laser typesetting machine for output.
Making the screen: Use 100~180 mesh polyester silk screen to make the screen, preferably using monofilament polyester mesh fabric. Then, use water-based photosensitive glue to make the plate.
2. Glass Treatment
Glass cleaning: Remove stains and moisture from the glass surface to ensure the glass surface is clean and dry.
Glass adhesive tape: Apply a plastic protective film on the glass surface that does not require frosting, sealing the edges with packing tape to prevent the chemical solution from leaking.
3. Frosting Processing
Preparing the frosting solution: Prepare the frosting solution according to specific process requirements. Common frosting solutions include hydrofluoric acid type, frosting paste type, and frosting powder type. When preparing water-based environmentally friendly frosting powder, mix components A, B, and water in a certain ratio, stir evenly, and then let it mature naturally.
Printing glass etching ink: Before printing, fully stir the frosting paste (i.e., screen printing ink), avoiding the use of iron tools, preferably using bamboo or wooden products. Evenly print the etching ink on the glass surface, and tools like squeegees can be used to increase the ink amount to ensure the desired ink volume is achieved.
Frosting treatment: Place the printed glass into the frosting solution and perform frosting treatment according to specific process conditions (such as temperature, time, etc.). During the treatment, the frosting solution will react with the ink pattern on the glass surface, forming a frosted surface with a special decorative effect.
4. Subsequent Processing
Rinsing: Rinse the glass after frosting treatment to remove residual chemical solution and ink from the surface. After rinsing, the glass surface will present a snowflake-like pattern.
Drying: Dry the rinsed glass to remove surface moisture.
Inspection and Packaging: Inspect the dried glass to ensure quality meets requirements. Then package it for transportation and storage.
Additionally, if the frosted glass is made using high-temperature baking methods, it is necessary to perform high-temperature baking after printing the ink. After baking, the frosted surface in areas without patterns will melt onto the glass surface, while the areas with screen-printed patterns will not melt onto the glass surface due to the effect of the melting inhibitor, thus creating a special decorative effect.
In summary, the processing and manufacturing process of frosted glass needs to be flexibly adjusted according to specific process requirements. At the same time, safety operations should be observed during processing to avoid harm to personnel and the environment.
