What should be noted in the laminated glass process for custom hot-melt glass processing in Foshan?

Release time:

Dec 30,2024

When using hot melt glass for lamination, the following aspects need to be considered:

1. Material selection and preparation

Glass materials:

Choose glass with high transparency, low density, and high strength as the bonding material to ensure that the laminated glass products do not easily explode or pose safety issues.

The glass materials should meet bonding requirements and must not have small pits or cracks to prevent hot melt adhesive from leaking or affecting the bonding effect.

Hot melt adhesive materials:

Select the appropriate type of hot melt adhesive based on the type and use of the glass.

Ensure that the quality of the hot melt adhesive is reliable, with good adhesion and stability.

2. Operating environment and safety measures

Operating environment:

Ensure that the operating environment is clean and dry, avoiding dust and debris that could affect the bonding effect.

Maintain suitable temperature and humidity conditions to prevent the hot melt adhesive from being affected by temperature or humidity changes.

Safety measures:

Wear appropriate protective equipment, such as gloves and goggles, to prevent burns from hot melt adhesive or cuts from glass shards.

During operation, avoid direct contact with hot melt adhesive or high-temperature glass to prevent burns.

3. Adhesive application and bonding

Adhesive application:

Before applying the adhesive, ensure that the glass surface is clean and free of oil, dust, and other impurities.

Evenly apply the hot melt adhesive, avoiding excessive application on one side that could lead to unreasonable shear stress and cause explosions.

After applying the adhesive, allow the hot melt adhesive to cool naturally to a suitable temperature before proceeding with the bonding operation.

Bonding:

Bond the glass panels coated with hot melt adhesive according to design requirements, ensuring that the positions of the two glass pieces are accurately aligned.

During the bonding process, apply appropriate pressure to ensure that the hot melt adhesive fully spreads and bonds the glass.

4. Subsequent processing and inspection

Cooling:

After bonding is complete, allow the glass products to cool naturally to room temperature to avoid rapid cooling or heating that could cause glass breakage or poor bonding.

Quality inspection:

Conduct quality inspections on the laminated glass products, including appearance quality, dimensional accuracy, and bonding strength.

Ensure that the glass products are free of bubbles, scratches, stains, and other defects, and that the bonding is firm and reliable.

5. Precautions and common problem handling

Precautions:

During operation, avoid splashing hot melt adhesive onto skin or eyes; if splashed, rinse immediately with cold water and seek medical attention.

Avoid storing unused hot melt adhesive in damp or high-temperature environments for extended periods to prevent affecting its bonding performance.

Common problem handling:

If bonding issues or bubbles occur, check promptly and re-bond.

If the hot melt adhesive experiences clogging or poor flow during use, check the adhesive application equipment or adjust the application parameters.

In summary, when using hot melt glass for lamination, attention should be paid to material selection and preparation, operating environment and safety measures, adhesive application and bonding, subsequent processing and inspection, as well as precautions and common problem handling.

Only by strictly following the operating procedures can the quality and safety performance of laminated glass products be ensured.
