a) wearing strip b) pouring
Description.
1---aluminum alloy profile;
2---Insulation material.
Figure 1 Schematic diagram of the composite mode of insulation profiles
Table 2 Composite methods and characteristics of thermal insulation profiles
Composite method a Insulation profile characteristics b, c
Wear strip
The linear expansion coefficient of the polyamide profile used in the strip profile is close to the linear expansion coefficient of the aluminum alloy profile, and will not be complicated by thermal expansion and contraction.
The joints are subject to large stress, slippage, and shedding. The strip profile has good high temperature resistance and optional cross section type
There are no special requirements for the production and processing environment of heat-insulating profiles, but the production process of the processes such as tooth opening and rolling is not properly controlled.
Can have serious effects (such as separation of polyamide profiles and aluminum profiles in use).
By adopting a non-I type complex shape polyamide profile, the heat transfer coefficient of the strip profile can be reduced, and the heat insulation effect of the strip profile can be improved. But adopt
The cross-section of the non-I type complex shape polyamide profile has a transverse tensile strength that is less than that of the profiled profile of the type I polyamide profile.
If the mechanical reliability check or the simulated load test is not performed before, it may cause accidental cracking during use.
With a strip of profile with a single polyamide profile, the composite properties may not meet the requirements of this section. For the wearing of structural parts, it is advisable to adopt
Double polyamide profiles
Pouring
The coefficient of linear expansion of the thermal insulation used in the cast profile is inconsistent with the coefficient of linear expansion of the aluminum alloy profile, but it is effective on the surface of the adhesive layer.
At the time, it is sufficient to ensure that the composite part of the cast profile does not cause slippage, peeling and the like. Cast profiles have good impact resistance and elongation
Extensibility, but if the production environment of the pouring process is not properly controlled, it will have a serious impact on product performance (such as low temperature fracture).
Casting profiles using Class I insulation are used at 70 ° C or higher, and the composite properties are attenuated, resulting in a decrease in load carrying capacity.
When the surface treatment of the aluminum alloy profile results in the insulation glue not being able to effectively bond the surface of the film layer, it is not suitable to be cast by composite method.
Thermal insulation profile
a At the same time there is a thermal insulation profile of the strip and cast composite, the performance of which must meet the performance requirements of the profiled and cast profiles.
b When insulation profiles are used in certain structural parts, they may be subjected to various loads and effects such as gravity load, wind load, earthquake action, temperature action, etc.
The demander should use the most unfavorable combination of effects as the load combination according to the environment and design requirements of the insulation profile, and the insulation profile under the load combination,
It is possible to calculate or analyze the stress indicators such as bending deformation, bending strength, longitudinal shear strength, and transverse tensile strength, so as to select suitable
Thermal insulation profiles.
c For the calculation method of the equivalent moment of inertia of insulating profiles, see YS/T 437.
