Information

For the heat-insulated broken bridge window profile that wears a single strip, its shear strength, especially under high temperature conditions, is not easy to meet the national standard requirements. Therefore, although it is cost-effective, its scope of application is particularly narrow. The comparison of single-branch and double-branch can be seen as follows:

   1. The use of single-strand broken aluminum doors and windows, the force balance of the heat insulation strip and the profile can be satisfied.

   2. The use of a single heat insulation strip has higher requirements for the quality of the opening of the blowing head.

  3. The aluminum profile for broken bridge aluminum doors and windows with double braces, the upper aluminum profile has two supporting points, which are balanced. However, in the case of a single bar, it is easy to be out of balance under the action of gravity, and it needs to be assisted by means such as a wheel.

  4. Use single-strand broken aluminum door and window profiles, and the rolling pressure should not be too large during rolling.

   5. In the surface treatment process, when the temperature reaches about 100 degrees, the hot melt glue line begins to melt, melt and fill the gap between the bottom of the heat insulation strip and the aluminum profile.

   When the temperature begins to drop, the molten glue line begins to solidify, and therefore has a strong bonding performance. The heat insulation strip is bonded to the aluminum door and window profile of the broken bridge, thereby improving the shear strength.
