I bring you a true story. Due to the continuous high temperature in a northern city this summer, a window of my friend's house was deformed. My friend doesn't know why. He called me. My preliminary judgment is that the problem occurred during the installation. He said no, spring is very good, that is to say, after this summer, it has become like this, and I thought of a serious problem. Is this a problem of bridge cutoff aluminum insulation strip? I asked him if it was caused by the deformation of the heat insulation strip. He really looks like that!
Nowadays, the requirement of living standard is getting better and better, and family users also attach great importance to decoration. In recent years, Duanqiao Aluminum has a huge market share of doors and windows, but most of the windows at home still have poor thermal insulation performance. The root cause is broken bridge aluminum insulation strip. The market is divided into PA66 nylon rubber strip and PVC. Many people do not know how to identify them. Let's talk about their views.
The bridge cutoff aluminum door and window insulation strips on the market are divided into PA66 nylon bridge cutoff aluminum door and window insulation strips. Brand doors and windows generally choose PA66 nylon tape, but the price will be a little higher. Some manufacturers will choose PVC to save costs. The thermal insulation performance and service life are a little poor.
For bridge cutoff aluminum insulation strip, we can identify it in this way. PVC surface is smooth and bright. When they are ignited, they will have a very strong smell of black smoke plastic, soft and not easy to break.
The frosted texture of PA66 nylon strip, cold extrusion technology, has a smooth surface but is not as shiny as PVC. The color is pure black. When burning, it will emit a burning feather smell. PA66 nylon rubber strip will break after being folded once or twice.
For the price of bridge cutoff aluminum, many people will compare profiles, glass, hardware and technology, but they forget the important thermal insulation performance characteristics of bridge cutoff aluminum. If the products on the market are sold too cheaply, we should pay attention to whether they are PVC insulation strips, and PA66 nylon strips should be of high quality.
The bridge cutoff aluminum insulation strip plays an important role in the bridge cutoff aluminum, which is also related to its width. How wide does the insulation strip of bridge cutoff aluminum need?
The width of bridge cutoff aluminum insulation strip ranges from 1.8mm to 50mm. The thermal insulation strip is a German technology. It passes through the middle of the aluminum alloy to achieve a good temperature difference between the inside and outside of the frame, so as to achieve a good thermal insulation effect. The wider the insulation strip is, the better the insulation effect is. First, after the bridge cutoff aluminum profile is extruded, roll on the upper gear with hobbing teeth, and then roll. In China, there are two sides: the interior is white, and the exterior is white. In foreign countries, it is generally put on the strip first, then sprayed, and sprayed on the insulation strip to make the temperature in winter and summer comfortable.
