    December 1,2021.

    Energy-saving brush strips for doors and windows are installed on the screen doors of subways and the revolving doors of hotels, or on the screen doors of some large equipment or machinery. Traditional door and window rubber strips have the shortcomings of high friction coefficient and non-flame retardant, easy to damage when moving doors and windows, and generate static electricity. 1. The base of the energy-saving sealing brush for doors and windows uses SUS304 with good corrosion resistance (>8% nickel content,>19% aluminum) or electro-galvanized sheet with stable structure and well-balanced color. 2. The base line of the base is straight, and the axis of the cross section is symmetrical. The hairs are sparsely dense and uniform in thickness, with the same height and length, without falling off, no loosening, and pulling resistance of ≥6KG. It can strengthen the sealing effect between doors and windows and prevent noise interference. The friction coefficient is reduced, which has a good energy-saving effect without losing the sealing performance. 3. Energy-saving brush strips for doors and windows have passed the SVHC test and comply with EU standards. The filament yarn is a functional nylon yarn with elasticity, strong resilience, high flexibility and good wear resistance. It is also anti-static and flame-retardant (extinguishes when it is separated from the fire, no burning objects fall), and appears smokeless and no radiation , Non-toxic, low-calorie. 4. The heat distortion temperature is as high as 185-190℃, the melting point is as high as 218-224℃, and the nylon density reaches 1.14. When it is ignited, it burns slowly, with white smoke. The color of the flame is yellow on the outer layer and light blue on the inner layer. 5. Let the sealing gap of the equipment no longer be restricted by the shape of the brush. The choice is diverse. The design is reasonable and suitable for various shapes. Steps to install the door and window sealing brush strips: First measure the door gap size, and customize the door and window sealing brush with a suitable height, so there is no need to replace doors and windows with great effort. In order to make the installation more convenient, the current brushes do not need to be punched, and only need to paste 3M tape behind the aluminum alloy bracket to use. After 3-5 years of use, it will not fall under normal conditions. If you add it, you only need to replace the tape on the back. It is very practical and beautiful, and the cost is relatively low. When choosing to buy door and window sealing brushes, it is also very particular. Generally, sealing brushes of different materials should be selected according to different use environments.

  • Why Is It Necessary To Install A Sealing Brush On The Screen Door?

    Why Is It Necessary To Install A Sealing Brush On The Screen Door?

    November 17,2021.

    China's high-speed rail construction and development are advancing by leaps and bounds. China's high-speed rail has grown from nothing to a world leader, and has gradually become China's business card and has become famous all over the world. The great convenience and comfortable riding experience that railway transportation brings to our daily travel is indispensable with a high-quality screen door sealing brush.   The door sealing brush is an important "green leaf role" on the screen door of rail transit. The sealing brush is installed on the left and right sides and above the screen door. So why do you need to use a sealing brush on a screen door? There are four main reasons.   1. When the high-speed rail train is moving forward at high speed, especially when passing through a tunnel, it will drive the air in the tunnel to flow at a high speed and produce "piston wind". The sealing brush will now take on the task of keeping the space sealed and dustproof. , Maintain good sealing and air tightness.   2. The fast running of the train will also bring a lot of noise. After installation, it can also reduce the discomfort caused by the noise and improve the passengers' good riding experience.   3. The sealed brush also has a good energy saving and environmental protection effect. When the car door switch is closed, it is easy to exchange hot and cold gas. The heat brought by the brake when the train enters the station will enter the waiting area. The entrance and exit of the platform will inhale the cold load formed by the air due to the piston effect of the train. And the cold and hot air in the tunnel are easy to be sucked away. The brush filaments are evenly distributed and the density is high. After installation, it can maintain 98.5% airtightness, which has a good energy-saving effect.   4. The sealed brush is flame-retardant. The brush wire with flame retardant function is not easy to be burned. Unfortunately, a fire incident in the car compartment can reduce the secondary damage caused by combustibles. (UL94-V0 grade brush filament burns for 10 seconds, the flame will be quickly extinguished within 30 seconds, and no burning material drips, and the combustion gas is non-toxic).   The aluminum alloy bracket of the screen door sealing brush can match a variety of door bodies. The styles are rich and diverse. The commonly used types are H, F, Y, and T. Aoqun manufacturers have a total of more than 70 styles for customers to choose from. More than one hundred high-speed railway trains have customized screen door sealing brushes that meet national standards, and provide customized services that can be customized with drawings, samples and designs according to customer needs.   Aoqun Brush brand screen door sealing brushes have passed SVHC testing and meet ROHS EU standards; sealed brushes that reach UL94-V0 flame retardant level meet EN45545-2 EU fire and flame retardant smoke toxicity test requirements, and are ...

Glass screen doors are used in railway transportation systems in Europe and Asia, and they are still one of the safety standards. The screen door separates the platform from the train operation space, and can be automatically opened and closed by the control system. Screen doors are most commonly used on high-speed railways and subways. There are mainly three types of subway screen doors: closed, open and half-height. Open and half-height are mostly used for barriers and aesthetics, so they are usually called "safety doors." Closed full-height screen doors are used for underground platforms. In addition to ensuring the safety of passengers, they also have the energy-saving effect of blocking the exchange of cold and hot airflow between the airflow in the tunnel and the cold air-conditioning environment in the train. The height of the door is generally 2.8 m ~-3.2 m, this structure is mostly used for platforms with air conditioning systems. The conventional half-height security door is 1.2~1.5 meters. Because it cannot completely isolate the impact of wind and noise on passengers, this structure is mostly used on ground platforms or elevated platforms. Half-height Screen Door Closed Subway Screen Door A brush will be installed on the screen door to be used together. We call it a "screen door brush". After installation, it can reduce the loss of cold and hot air in the waiting room caused by air convection, and insulate cold and heat; it can also reduce the generation during train operation. The noise, good sealing effect, can create a safe and comfortable riding environment for passengers, and has the functions of energy saving, environmental protection and beauty.
