[China Aluminum Industry Network] 1. Design of heat insulation aluminum profiles 
In the design of systematic energy-saving doors and windows, the design of heat insulation aluminum profiles is the core part of the entire design. The quality of profile section design determines the performance and quality of doors and windows. The principle of heat insulation is to mechanically roll the non-metallic heat insulation strip (nylon 66) and two sections of aluminum alloy profiles into an insulated profile. In the profile design process, the main considerations are the effects of wind loads, comprehensive strength, stiffness and stability requirements. The optimal design is carried out. Under the conditions of economical cross-sectional area, the moment of inertia I and the cross-section resistance moment W are as much as possible. Increase. In the cavity after insulative heat insulation strip, urethane resin with “insulation king†is irrigated, and the energy convection effect of heat convection is more significant.
2, the gap weatherproof design In order to obtain better watertight, the use of equal pressure principle design isostatic glue, and drainage channels on the window frame material to divert rainwater, in order to obtain better air tightness, with sealant Bars to prevent air infiltration.
3. Hardware accessories Hardware accessories occupy a very important position in the systematic design of energy-saving doors and windows. The quality of hardware accessories affects the performance of doors and windows. The repetitive opening of doors and windows is achieved by hardware accessories. Therefore, it is also crucial to select high-quality hardware accessories. The quality performance of hardware accessories directly relates to the processing quality of doors and windows.
When designing systematic energy-saving doors and windows, we completely adopt the European standard notch, combined with special hardware, connecting and cutting, and the hardware runs smoothly and freely in the profile channel and is flexible to open and close. Can use imported hardware accessories, can use domestic accessories, can meet different levels of demand 4, hollow glass system of energy-saving doors and windows of the sound insulation performance is achieved by the hollow glass, while the energy saving of doors and windows is also insulated glass to block heat radioactive.
5. The design of rubber strips The material of the strips is EPDM rubber. Its advantages are: good weather resistance, good heat resistance, and good sealing performance. The main design considerations are: safe, convenient and reliable, watertight and airtight and reliable. As shown in the figure below, isotonic strips are used to retain water and airtight on the front; hollow strips are used for the second airtight; tower strips are used to press the glass.
