Tempered Double Silver LOW-E Energy saving Glass:

Reprocessing performance: Stable and reliable performance, capable of long-distance transportation of single pieces, achieving remote tempering processing and hollow synthesis;

Optical performance: suitable light transmittance, ensuring sufficient natural lighting indoors;

Thermal performance

comfort

UV protection: Special LOW-E film material, effective damping to block UV damage to the skin, effectively reducing furniture fading and deterioration caused by UV radiation.

Preventing air conditioning diseases: reducing the use of air conditioning in summer and indoor heating and electric heating in winter, delaying indoor drying, and promoting healthier physiological functions.

No condensation: LOW-E energy-saving insulated glass has good sealing effect and excellent anti condensation performance.

Soundproofing: The general urban environment noise is about 75dB, and using insulated energy-saving glass indoor noise can be reduced to below 40 dB, similar to the peaceful state of rural wilderness.

1、 Open the box

1. The glass manufacturer's products are packaged in wooden boxes, sealed with double-layer plastic film (with built-in desiccant, sunshade, moisture-proof), and coated with protective film (facing the box). Foam pearl cotton is placed between the glasses;

2. Follow the arrow mark on the side of the box to open the box, and take a piece from the glass surface facing the opening direction (the opposite side of the coated surface).

2、 Cutting

1. Cutting requires the use of oil-free cutting method on the coated surface of the glass for operation;

2. If using automatic or semi-automatic mechanical cutting or manual cutting with a roller type cutting knife, it is recommended to work directly on the protective film:

3. If wrinkles are found in the protective film during the cutting process, they should be smoothed first before continuing the operation.

3、 Stacking up

1. Glass should be stacked on either an 'A-frame' (with a 6-7 ° angle) or an 'L-shaped frame', with no more than 30 stacked pieces on each side.

2. Glass that has not been tempered after cutting should be stacked with its coated surface facing the outside of the A-frame.

3. The glass that has been cut and tempered shall be stacked with the coating surface facing inward, except for the Z-inner glass which is stacked with the coating surface facing outward.

4. Dry cardboard or equivalent separators should be used to separate tempered glass from each other to avoid scratching the film surface. Glass with different sizes, thicknesses, and specifications must be effectively isolated at the junction, otherwise the film surface of larger pieces of glass is easily crushed.

4、 Grind the edges

1. The protective film on the coated surface cannot be peeled off during edge grinding.

2. The rollers, supports, and clamping belts of the edging machine must be cleaned before edging. The clamping belt should not be too tight and can be raised by about 0.2mm according to the thickness of the glass

3. The cooling water used to cool the grinding wheel must be replaced frequently and must not carry large hard particles to avoid scratching the LOW-E film surface.

8、 Hollow synthesis

1. When synthesizing a hollow, the glass edge that will be bonded to the sealant must first undergo a coating removal process (commonly known as film removal), and the film layer must be completely peeled off.

2. After removing the film, glass cleaning must be carried out using a specialized soft bristled brush, and pure water with a resistivity greater than 10M Ω should be used for cleaning, otherwise residual marks may be left, affecting the appearance quality.

3. Adhesive compatible with coated glass should be used for bonding.

4. Hollow synthesis must use double or multiple sealing processes, with 3A molecular sieve filled on all four sides of the spacer. The entire operation process should maintain the sealing of the hollow glass and the dryness of the air inside the hollow layer to avoid affecting the product's service life.

*Regarding processing time

1. After opening the glass box, cutting, edging, tempering, and synthesizing the hollow should be carried out as soon as possible. It should not be exposed to air for too long, otherwise it is easy to cause oxidation of the glass coating surface. All the above processes must be completed within 24 hours.

2. It is recommended that each of the above processes be completed within 4 hours, and each process should be arranged reasonably according to the processing efficiency of the equipment to avoid oxidation caused by excessive exposure of the glass coating surface.

3. If the processing cannot be completed within the specified time, the product must be resealed, dried and packaged, and filled with nitrogen gas. The storage time should not exceed 60 hours. Exceeding the specified time may cause oxidation of the film layer.

*Other precautions

1. During the entire processing, the coating surface cannot be adsorbed by suction cups.

2. The glass of the same project should be processed in the same tempering furnace, and the production should retain the project sample for comparison and inspection during subsequent production.

3. The performance and appearance of glass before and after tempering are different and cannot be mixed.

4. The color of tempered LOW-E products is closely related to the thermal history of the glass, so it cannot be returned to the furnace.

5. When synthesizing hollow materials, the coating surface of LOW-E glass should be placed on the second surface (i.e. the hollow glass facing outdoors is LOW-E glass, and the membrane surface faces the air layer of the hollow glass).
