Speaking of sealing strips, I believe that there are friends who have installed doors and windows are more aware of the doors and windows after the installation, there will be some gaps in order to make the doors and windows more acoustic and sealing, will choose to use the sealing strips. In order to make the doors and windows more soundproof, good sealing, will choose to use the seal. So how to paste the door seal? How to choose the seal? With these two problems we take a look at it!
How to stick the door seal:
First of all, the door position of the debris, dust clean, easy to seal and slot paste more closely; Secondly, tear open the seal, paste in the designated position, and let the seal ends were to the center of some retraction before cutting; Finally, to be a good seal paste, need to use the hand to press a few minutes, so that the seal is more tightly adhered to the door.
How to choose the seal:
1, sun exposure method
Market seal is divided into PVC and silicone rubber and other materials, PVC material surface is not light and feel stiff, there is no elasticity, while the silicone rubber material is slightly more expensive, but the feel of softness and elasticity, and will be placed in the sun, or placed in a 200 ℃ environment will not have any change, on the contrary, PVC material, but the price is slightly expensive, but soft and flexible, and will be placed under the sun, or placed in 200 ℃ environment. Changes, on the contrary, PVC material in the sun exposure will become soft, the surface of the oil spill.
2, cold shrinkage test method
Secondly, if the two materials at the same time in the refrigerator for a period of time after taking out, you can see the PVC sealing strip becomes stiff, a folded on the break; and silicone rubber sealing strip without any change. Therefore, it is recommended to choose silicone rubber sealing strip, not only not affected by the hot and cold environment, but also has a buffer effect, can be very good protection of doors and windows.
3, open-flame combustion test
Finally, the two materials of the sealing strip combustion, we can see that PVC combustion will be black smoke, and will also be blistering contraction, pungent odor, but also residual hard plastic, can not be completely burned. Silicone rubber is very environmentally friendly, combustion can be done without smoke and odor, fully burned into white powder.
Summary: The above is to introduce you to the door seals how to paste and how to choose the sealing strip of the relevant content, I hope to be able to bring help to friends in need, later if you still need to know more knowledge, welcome to pay attention to Qijia network information.
Compared with ordinary sealing strip, what are the characteristics of silicone rubber sealing strip?Silicone rubber sealing strip is completely different from ordinary rubber strips, such as common JOPU rubber, it has a stronger resistance to compression deformation performance, so the sealing contact surface can be made larger, extremely effective in blocking the activities of the window part of the leakage in the noise.
Silicone rubber strip related to the introduction ofAs we all know, silicone rubber, also known as silicone, synthetic rubber in the Silicone Rubber Seal excellent products. It is not only no flavor does not contain toxicity, can withstand cold, high temperature, even in 300 ℃ and -90 ℃ environment is still unharmed. And today we want to introduce the silicone rubber strip is made of silicone rubber into the production of sealing strips.
Silicone rubber seals are very popular, which is determined by its characteristics. Silicone rubber sealing strip appearance transparent and smooth, soft and elastic to the touch, more people love is that it does not contain toxicity, no smell, but also environmental protection. Its elasticity in the Shore 35-75 degrees, high temperature resistance. If Silicone Rubber Seal you have used it, you will love it durable and resistant to minor acids and alkalis and some other characteristics. It is commonly used as a seal in medical, industrial, electronics, and mechanical fields.
Here are its index parameters:
Square resistance of 1014 ohms
Dielectric loss factor less than or equal to one percent
Tear elongation greater than or equal to 200%
Volume resistivity greater than or equal to 1014 ohms
Shaw's hardness of 30-80+5
Long-term temperature resistance up to minus 70 degrees Celsius to 250 degrees Celsius, short-term 300 degrees Celsius for a few hours
Tear strength of up to 4.0 to 8.0Mpa
Tear strength of 15-KN/M
The dielectric strength of the dielectric is 20KV/MM
By the simple introduction, you may be on the silicone rubber strips are still feel a little strange. However, life we do not use it quite a lot, due to good performance, it is often used to prevent some small insects climb in, dust, sound insulation, fixed density and other roles. Such as daily life of the gap between the windows and doors need to use it, sealing good seal can be thermal insulation and energy saving and wind it, so many people in the installation of windows and doors will be affixed with silicone rubber.
Silicone rubber strips may be used in industry, medical and some other areas more. Because it is very good in both high and low temperature resistance, such as the life of the lighter tube, medical infusion or wire and cable and other products that require excellent sealing strip will use it. Some manufacturers produce some colorful silicone rubber strips to make it more aesthetically pleasing.
So how do we differentiate between high grade silicone rubber strips and poor quality PVC sealing strips?
Generally speaking, with a pungent odor, the price is relatively cheap, when burning will bubble, shrinkage is PVC sealing strip, while the senior silicone rubber strip will only have a little bit of alcohol flavor, almost can not smell, burning is also almost smoke-free and odorless, silicone rubber strip combustion is sufficient, while combustion produces a substance is white powder.

Silicone sealing strip a bundle of how many metersSilicone sealing strip a bundle of 100 meters. According to the query related public information shows that the production size and length of silicone sealing strip is uniform, manufacturers factory set 1000 meters output 10 bundles, the current common silicone sealing strip is 100 meters a bundle.
