Let’s analyze the various properties of the material.
The linear expansion coefficient of the material@Roystar
The temperature of the solid material changes every time
Celsius The ratio of the change in length to the length at ℃ is called the linear expansion coefficient of the material. The thermal insulation profile is a composite profile made of aluminum profiles and thermal insulation materials. If these two If the linear expansion coefficient of the material is inconsistent, it will inevitably cause its elongation or shrinkage to be different when exposed to heat or cold, thus affecting its use. If the difference is too large, it will inevitably lead to This composite structure is destroyed.
This is because the spacing of the tooth patterns on the aluminum profile notch during the tooth opening process is about
(between tooth valley to tooth valley) distance) (as shown in Figure 1). If the linear expansion coefficient difference between the insulation material and the aluminum profile is too large, it will inevitably cause the expansion and contraction of the insulation material to exceed the tooth spacing on the notch of the aluminum profile when the temperature changes, resulting in < br/>Tooth skipping
The situation of this
Tooth skipping
occurs twice will inevitably lead to a significant reduction in the shear force of the entire insulation profile or damage to the insulation strips This affects the use of thermal insulation profiles.
