We know that hollow glass doors, the thermal conductivity of glass is 0.77W / mk. The thermal conductivity of air is 0.028 W / mk, shows hollow glass, the thermal conductivity of glass is 27 times the air 12mm hollow glass, and the presence of air in the active molecules such as water molecules, that affect the energy conduction hollow glass transfer and convective transfer performance of the key factors of hollow glass, thereby improving sealing performance insulating glass, is an important factor to improve the insulation performance of insulating glass. ② Shui: the excess glue along the middle of the space layer of insulating glass smooth, so that there is no excess glue outside presence; ③ Pinch: pinching the two sheets of glass, because the elimination of the pressure, causing the glass to the outside Shui separation caused clearance. Attention problems ① strip exit temperature hot press; ② tape sealing temperature, thickness, flatness, displacement; ③ tape sealing surface bonding integrity; ④ tight seal between.
