6 white glass g film layer j film layer h film layer represents what?

Draw with a pencil with hardness H to see if there are any scratches. Less than h if there are scratches, and greater than h if there are no scratches.

6 Low E: 6mm thick low-emissivity coated glass, 2 1 13 low e = low radiation, and low E glass is low-emissivity coated glass.

6mm:6mm thick colorless glass, also called white glass.

High performance insulating glass is different from ordinary insulating glass. In addition to sealing the dry air between the two layers of glass, a special metal film with good thermal performance should be coated on the middle air layer side of the outer glass. It can cut off a considerable part of the energy of sunlight 526 1 to the room, and play a greater role in isolating 4 102 heat.

hollow glass

Insulating glass consists of two or more layers of flat glass. Two or more pieces of glass are bonded and sealed with sealing strips and glass strips, and are surrounded by high-strength and high-airtightness composite adhesive. The middle is filled with dry gas, and the frame is filled with desiccant to ensure the drying of air between glass plates.

According to the needs, glass original plates with different properties can be selected, such as colorless transparent float glass embossed glass, heat absorbing glass, heat reflecting glass, laminated glass, tempered glass, etc. And a frame (aluminum frame or glass strip, etc.). ) can be glued, welded or welded.

Its structure is shown in the sectional view of double-layer insulating glass. 3, 4, 5, 6, 8, 10, 12mm thick original glass can be used for insulating glass, and 6, 9, 12mm interval can be used for air layer thickness.

The thermal conductivity of glass is 27 times that of air. As long as the insulating glass is sealed, the insulating effect of insulating glass is the best.

There is a certain space between the glasses of insulating glass. The frame is filled with desiccant to ensure that the air between the glass plates is dry. The distance between two layers of insulating glass is generally 8 mm.

High performance insulating glass is different from ordinary insulating glass. In addition to sealing the dry air between the two layers of glass, a special metal film with good thermal performance should be coated on the middle air layer side of the outer glass. It can block the considerable energy of the sun to the room and play a greater heat insulation effect.
