Online low-e coated glass product instruction manual

1 Product Description

In-line Low-E coated glass, referred to as in-line Low-E, uses chemical vapor deposition coating (CVD) technology to continuously and uniformly deposit coating materials in gaseous form on the upper surface of high-temperature, clean, continuously moving float glass to form a metal oxide structured film layer through a chemical reaction, which becomes part of the glass as the glass cools. The stable oxide structure and high temperature coating properties make online Low-E glass chemically stable and free from oxidation problems; strong and durable, heat bendable, temperable, and single piece storage. The excellent physical and chemical properties make the energy-saving effect of buildings remain stable for a long time, and when sealed into hollow or vacuum glass, the film layer will not deteriorate even if the adhesive ages and cracks and loses its sealing properties, and the low radiation function will not fail, so it is called "hard coated" glass.

2 Product deep processing

2. 1 Transportation and storage

2. 1.1 In the process of transportation and storage, the packaging and interior of the products must be waterproof; ensure the temperature inside and outside the glass packaging is the same and prevent condensation.

2. 1.2 The environment and place for storing the products should be dry and ventilated to prevent rain and running water, etc.; they should not be exposed to sunlight to prevent the glass from being damaged by heat.

2. 1.3 When using lifting equipment to carry, effective measures must be taken to prevent damage to the edge of the glass.

2. 1.4 Glass products must be protected from violent or continuous impact.

2. 2 Handling

2.2.1 In order to maintain the cleanliness of the coated surface, clean cotton-type labor protection gloves should be worn when handling single pieces. 2.2.2 When handling with suction cups, the suction cups should be wrapped with cotton-type cloth to avoid the contact of adhesive substances with the film surface. If the suction cups are not wrapped with cotton, they should be adsorbed on the non-coated surface. Try to avoid oil stains and other debris attached to the coating surface, and do not use hard metal objects to contact the glass film surface.

2.2.3 Lifting and loading and unloading (handling) process of the glass box to apply force evenly and smoothly, pay attention to light handling and light placement to prevent the glass shock crack.

2.3. Cutting.

2.3.1 The cutting table should be kept clean when cutting, and the coating surface should be placed facing upward to prevent the film surface from being scratched by broken glass chips.

2.3.2 A rapidly evaporating cutting oil should be used and cleaned promptly after cutting.

2.4 Film surface identification

2.4.1 Touch method: touch the glass surface gently with fingers, the smoother one is the glass surface, the one with astringent feeling is the coated surface.

2.4.2 Resistance method: test the glass surface with an ordinary multimeter, the side with infinite resistance is the glass surface, and the one with small resistance is the coated surface.

2.4.3 Conductive film pen test: the user is equipped with a special test pen for conductive film, used to test the low-E glass film surface. The two probes at the end of the pen will be in light contact with the glass surface at the same time, and if the indicator light is glowing, the surface is coated; if not, the surface is not coated.

2.5 Tempering

2.5.1 "Hard coated" glass can be toughened.

2.5.2 The thermal processing parameters are different from those of ordinary float glass because of its low radiation properties.

2.5.3 Tempering process parameters (reference)

Table 1 Normal radiation furnace tempering parameters

Type Upper temperature ℃ Lower temperature ℃ Heating time S

5mm online Low-E 700 710 220~240

6mm online Low-E 700 710 240~260

Table 2 Convection radiation furnace tempering parameters

Type Upper temperature ℃ Lower temperature ℃ Heating time S

5mm online Low-E 680 690 220~240

6mm online Low-E 680 690 240~260

2.5.4 Special matters The ordinary furnace needs special fine adjustment of tempering process parameters to achieve rapid temperature rise as much as possible; quickly make the glass reach thermal equilibrium and reduce its residence time in the hot environment. As the glass temperature rises during tempering, the film surface should not be in direct contact with the roll surface as much as possible to avoid accidental damage to the film layer.

2.5.5 Bending Tempering "Hard coated" glass can be bent and tempered. When bending and tempering, the temperature is high and the film surface is facing upward to avoid accidental damage to the film layer. The heat treatment time should be slightly longer than that of ordinary colorless glass.

3. Product Application

3.1 Monolithic

Online Low-E glass is "hard coated" with oxide film structure and can be used as a single piece.

3.2 Hollow

Online Low-E glass can be used in combination with insulating glass for better energy saving effect. It is recommended that the film surface is located on the 3# side, and can be combined with the body tinted glass, online or offline sunlight control coated glass, which makes a perfect combination of colorful decorative effect and heat insulation and heat preservation function, and shows the diversity of the glass with transparent light, rich color and energy saving, and can keep the comfortable temperature in the room.

When combining online Low-E glass with insulating glass, there is no need to remove the edge film layer.

3.3 Laminated

When making laminated glass with online Low-E glass, the non-film surface should be made to contact with the film to combine, and it is recommended that the film surface is located on the 4# surface when using single piece of laminated, and the film surface is recommended to be located inside the insulating glass when synthesizing the insulating glass.
