PA66 nylon insulation strip
broken bridge aluminum doors and windows profile partition, cut off heat conduction. Broken Bridge aluminum doors and windows the reason why the conduction of indoor and outdoor temperature can be isolated is that the insulation strip is used to isolate indoor and outdoor temperature, making indoor and outdoor temperature non-conduction. However, the traditional old-fashioned aluminium windows makes the temperature conduction very fast because of heat metal conductivity.
1. How to distinguish whether the heat insulation strip is PA66 or PVC
1. Fire judgmental methods: after ignition, there will be short-term combustion and then self-extinguishing. PA66 nylon insulation strip is the one with the smell of protein burning; The one with the smell of fire is self-extinguishing, and the one with pungent smell is PVC insulation strip.
2. External observation: the surface of the nylon strip PA66 of the Broken Bridge aluminum window is a matte texture, and the color is black; PVC strip looks smooth, smooth, and the color is white.
2. Features of PA66 nylon insulation strip:
1. The biggest advantages are:
wear resistance, aging resistance, high temperature resistance, strong chemical corrosion resistance and UV resistance
.
2. The expansion coefficient is close to that of aluminum profile, which ensures that the heat insulation strip and aluminum material are durable and closely combined under the condition of sun exposure and cold freezing.
3. The processing temperature of the heat insulation strip is as high as 235 degrees, which completely meets the technological operation of the Broken Bridge aluminum profile after the first threading and spraying.
4. The dimensional accuracy is less than 0.05mm to ensure the air tightness and water tightness of broken bridge aluminum windows.
3. What kind of insulation strips are used for broken bridge aluminum windows of different series?
60 series broken Bridge aluminum, insulation Strip width 20mm;
65 series broken Bridge aluminum, insulation Strip width 20mm;
70 series broken Bridge aluminum, insulation Strip width 20mm;
75 series broken Bridge aluminum, insulation Strip width 25mm;
80 series broken Bridge aluminum, insulation Strip width 30mm;
the above parameters are selected from Zhongwang broken bridge aluminum, and aluminum profiles of different brands may be slightly different.
