Is there a difference between thermal insulation and broken bridge aluminum insulation strips?

1. Looking at the gloss, the surface of the nylon strip PA66 of the broken bridge aluminum window is a frosted texture, and the color is black; But the PVC strip looks smooth, smooth, and the color is white. The two can be clearly distinguished when compared together, 2. Another point is that nylon strip PA66 is non-combustible, PVC strip will burn after a while to see a small flame, and there will be a general plastic smell, as long as you observe carefully, you will be able to distinguish nylon strip from PVC strip.

There is a difference, the heat insulation strip has nylon and PVC, and it is generally better to import

Of course, there are nylon PA66 strips, PVC strips and so on in the domestic market, even if it is nylon PA66 strips, there are many kinds of raw materials, as well as the difference between new materials and first-class materials, the quality and performance are very different, and there are many differences, so we should pay attention to the choice, otherwise it will bring great quality hazards and safety hazards to production and product quality.

Summary. 1.Different thermal insulation There are certain differences between these two materials in thermal insulation, and broken bridge aluminum does a better job in this regard, because it adds thermal insulation materials, which can effectively block the outside temperature. And the thermal insulation of aluminum alloy itself is not very good.

2.The sound insulation effect is different They will also be different in the sound insulation effect, although both have a certain sound insulation effect, but the broken bridge aluminum interlayer is added to the sound insulation material, so the sound insulation effect will be better.

3.Different hardness The hardness between broken bridge aluminum and aluminum alloy is different, for aluminum alloy, after being hit by the outside world, it is easy to deform, while the hardness of broken bridge aluminum is relatively high, even if it is impacted, it is not easy to deform.

4.Different sealing performance Broken bridge aluminum and aluminum alloy are also different in sealing, aluminum alloy door after a period of use, it is easy to appear that the closure is not tight. The broken bridge aluminum inner cavity has a 5-channel sealing design, so the sealing effect is very good.

Is there a difference between broken bridge thermal insulation aluminum alloy and thermal insulation aluminum alloy?

Dear, hello, please wait, we have seen your question, and we are quickly sorting out the information for you, and we will send your answer to the little master immediately. Thank you for your support, recognize my service, and remember to give a thumbs up<>

Summary. Dear, each of the thermal insulation strips has a PA66 logo! The details are as follows:

The insulating strip is black and matte, and the laser coding of trademarks, product specifications, production batch numbers and other contents can be seen at about 60 cm apart on the strip.

2.Moreover, the whole is smooth and flat, no shrinkage holes, no looseness, no scratches and abrasive extrusion marks, and the unique luster of minerals can be seen in the light, that is, the uniform distribution of glass fiber, and the cross-sectional incision is smooth and delicate.

Whether there is a sign on the insulation strip of the broken bridge aluminum profile.

Dear, each of the thermal insulation strips has a PA66 logo! The details are as follows: the heat insulation strip is black and matte color, usually on the strip every 60 centimeters or so, you can see the trademark, product specifications, spring shooting, production batch number and other content of laser coding.

2.Moreover, the whole is smooth and flat, no shrinkage holes, no looseness, no scratches and abrasive extrusion marks, and the unique luster of minerals can be seen in the light, that is, the uniform distribution of glass fiber, and the cross-sectional incision is smooth and delicate.

Kiss, the structure of the insulation strip is extremely useful as follows:1The thermal insulation strip is the core structure of the thermal insulation profile, which is the "broken bridge" on the heat transfer path in the aluminum profile, reducing the transfer of heat in the aluminum profile; It is also the structural connector of the aluminum profile on both sides of the thermal insulation profile.

2.By its connection, the three parts of the insulating profile become a whole and bear the load together. It is different from the rubber strip in that it is made of new composite material by mechanical rolling, which cannot be replaced separately, and can only be replaced with the whole profile.

It <> more than 65% polyamide PA66 (commonly known as nylon 66) and 25% glass fiber and 10% primary additives. The main raw materials of high-quality broken bridge aluminum thermal insulation strip are more than 65% polyamide pa % glass fiber and 10% additives, the polyamide in these raw materials determines the very pure and multi-characteristic of the thermal insulation strip, such as tensile strength, linear expansion coefficient, etc., inferior broken bridge aluminum thermal insulation strip not only has poor tensile strength, but also the linear expansion coefficient is far from the same, which can easily lead to the occurrence of window accidents, and the glass fiber in the raw material has a direct relationship with the strength of the broken bridge aluminum thermal insulation strip, and 10% of the raw materials The additives have a great relationship with the anti-aging performance, stability and water absorption resistance of the insulation strip.

The heat insulation strip used in the broken bridge aluminum alloy is made of PA66GF25 heat insulation strip, which is the heat insulation strip used in Wells aluminum profiles.

PA66GF25 Thermal Insulation Strip is a series of PA66 modified engineering plastic alloys, which have high melting point, excellent heat resistance and self-extinguishing properties. However, the PA66 material has not been modified in the tensile strength and linear expansion coefficient and the aluminum Hehe Fan Xijin is not matched, through the actual Zen test, in the PA66 plus 25% of the glass fiber modified into engineering plastics as the basic material of the insulation strip, at present, there is no international car Liang this more reasonable, more economical heat insulation strip new material, of course, all doors and windows of Wells are selected PA66GF25 as the heat insulation strip.

Summary. Let's first take a look at what is broken bridge aluminum alloy, 1The front and back sides of the broken bridge aluminum are made of aluminum alloy, and plastic is used as a cavity in the middle.

Aluminum alloy is a metal material, so the thermal conductivity is very good, when the outdoor temperature difference is large, aluminum alloy can become a way to transfer heat.

2.Broken bridge aluminum can cut the aluminum alloy from the middle, it uses hard plastic to connect the broken aluminum alloy, while retaining the advantages of the two materials, but also plays a decorative role, and its strength and aging resistance are also very good.

Is there a heat insulation strip on the reverse side of the broken bridge aluminum?
