ã€Aluminium Road Network】 This is a time of embarrassment. Outdoor noise, like the impetuous heart, has become an obstacle to our happiness. In recent years, the yearning and pursuit of "quiet" life has led to the emergence of silent doors, windows and locks. With the immediate awareness and in-depth digging of user needs, in the context of consumer upgrades, silence will become the next outlet for the doors and windows industry. Why Silence is the Next Door in Windows and Door Industry The so-called noise, in acoustic terminology, refers to the sound produced by the irregular vibration of an object, that is, the sound of a change in pitch and sound intensity, which sounds inharmonious. If environmental science terminology is used, it refers to annoying sounds that interfere with people's rest, learning, and work. Why mute will become the next door in the window industry? Because there are too many people in China have been sleeping in the noise. In 2017, the “Environmental Noise Pollution Prevention and Control Report of China (2017)†released by the Ministry of Environmental Protection showed that the total compliance rate of acoustic environment at night in the national urban functional areas was only 74.0%. In other words, at least 26% of urban households must sleep in excessively noisy environments. Sina released the "white door mute and home hardware white paper" shows that 95.12% of netizens expressed disgust on the interior door lock noise. Not only that, door hardware, home hardware, and bathroom hardware also have annoying noise. Studies have shown that in a relatively quiet indoor environment, when "abrupt" noise reaches 60 decibels, 70% of people can wake up, affecting sleep and causing fatigue. The ubiquitous environmental noise and consumer's increasing dislike of noise have not only made the brand of quiet doors and windows and door locks that have been pre-empted in the air outlets achieve rapid development, but also become a new trend in the transformation and upgrading of the entire door and window industry. Professor Tang Zhonggao, deputy director of the China Industrial Design Association and deputy director of the Institute for Design Strategy and Prototype Innovation at the Art and Science Research Center of Tsinghua University, analyzed and predicted that with the continuous improvement of people’s quality of life, the demands for family life and health have become increasingly strong. The attention of family noise will be higher and higher, and the demand for silent products will continue to increase. Silent leading doors and windows industry design new fashion brands have launched mute new series Analysis of the industry pointed out that with the upgrading of consumption, silent doors and windows, and door locks, has become a household just need. In addition to the great attention at the major exhibitions, on the road leading to “silenceâ€, the major brands in 2018 are also extremely passionate. As early as the end of 2017, TATA focused on the silent door, it was the first to launch a new product in 2018 - "super silent three big parts" including outer doors, interior mute doors and silent wallboards. The exterior doors are designed for the balcony and outdoor space, with environmentally friendly oak materials and water-based paint, sealing, sound insulation, insulation, and safety; the interior mute door adopts a 45° inclined mouth plug design, using soft rubber strips and magnetic absorption; sound insulation wall panels The use of solid wood materials, and built-in glass in the structure, effective sound insulation 37.5 dB. Seeing that TATA held the mute flag in the end market, in 2018, silent doors and windows have become the key to upgrading many first-line brands. At the Beijing Gate Exhibition last month, Holtz Wooden Door held the new product launch conference with the theme of “Jing Shiâ€. The “Fire-retardant Door in the Living Room†was officially released, and the excellent mute performance was one of the important selling points of the product. On April 10th, Wang Li corn door released new products, around the basic standard of silence, to achieve the Wang Li corn door “four soundproofing†technology, to achieve complete sound insulation in the true sense, to create a sweet for their own space. Huangpai doors and windows are launched eight mute protection, in order to achieve the net, net ear, clean room, net, net energy, "static" effect. With the popularity of silent doors and windows, silent doors and windows associated with silent doors have also become the darling of the market, and to promote the quiet upgrade of the wooden door industry. Taking the silent door lock mute door lock as an example, through the cooperation of a series of components such as a mute door lock, a mute bumper, and a silent hinge, the overall noise is reduced when the door is opened and closed. Under the impetus of Mingmen's silent door locks, "China Lock and Home Hardware Mute White Paper" and "Chinese Family Silent Consumption Trend Blue Book" have been released. Not only that, on the day of World Noise Day on April 16th, 2018, Mingmen's silent door locks were also combined with Netease Home Appliances. They issued an initiative through the public forum and released the first microfilm of the silent door lock industry. They called for more public attention to home interior noise hazards for happiness. Help. From silent doors and windows to mute door locks How far are we from "quiet" life? Through the launch of a series of silent new products in 2018, it is not difficult for us to find that the pursuit of “quietness†has shifted from outdoor to indoor. When we mentioned space noise reduction in the past, the first thought might be noise-insulating windows made of sound-insulating glass. However, the sound-insulating windows can block outdoor noise, but they cannot stop the transmission of indoor noise. Nowadays, in order to achieve a new “static†world, major brands have begun to think of ways to reduce indoor noise, such as the use of silent doors or silent door locks to reduce the generation and transmission of indoor noise. Accompanied by the major brands have joined the "quiet" camp, quiet technology is also sesame blossoms. The brand new series of doors and windows of the Emperor brand in 2018 took the lead in adopting the new sound insulation technology of “eightfold silent protection, nine-layer sealing, and ten-fold reinforcementâ€. Compared with ordinary windows and doors, its sound-insulating effect was improved by a factor of 2. Fuxing doors and windows adopt high-quality profiles and High-grade imported hardware accessories, the cavity adopts EPDM sealant and door frame, so as to achieve a more comprehensive sealing effect; In addition, Fuxuan's doors and windows products are equipped with 5mm+12A+5mm hollow glass, including The vacant layer is filled with an inert gas, argon, which effectively reduces acoustic resonance and also hinders the transmission of sound, successfully reducing the noise to below 40 decibels. However, industry analysts have pointed out that the muting of wooden doors is not only a barrier to outdoor noise during door closing, but also a quiet experience during the opening. The realization of this kind of experience requires the tacit cooperation between the wooden door and the hardware. Therefore, only when the noise-isolation wooden door is matched with the exquisite hardware with mute function, can the significant improvement be achieved in the silent experience. At the same time, as Chen Li, chairman of Mingmen’s silent door locks, puts it, reducing noise is like a system project, as it is to treat air pollution. Your walls, doors and beds are soundproofed. Air conditioners and refrigerators are muted. Toilets and floors are muted, but your door lock noise can be silenced by putting all the above mutes into a single vote. In household products, even a small amount of noise in one hinge will break your quiet life. In creating a quiet environment, home products are equally important regardless of size. Therefore, even if quiet doors and windows and mute door locks have arrived, we still have some distance from the real "quiet" life. You must not know the five major household noise noise reduction artifact 1, sound insulation wall How is the wall insulated? Generally recommended soundproof walls are generally filled with sound-absorbing cotton or PU inside, and some simply use cardboard to partition into a so-called honeycomb structure, on the one hand to increase the strength of the door panel; on the other hand, a closed air layer formed by The degree of sound insulation. 2, soundproof ceiling Special sound insulation ceilings are made with professional sound insulation materials, and the method of saving money is to use light steel frames and mineral fiber boards as ceilings. 3, mute doors and windows The number of decibels (25-40) that can reduce or reduce the noise, because the general outdoor noise environment is about 75 decibels, and when the noise is reduced to about 40 decibels, the human ear can be considered a more comfortable environment. 4, noise floor Due to the superior sound propagation and damping properties of cork, softwood flooring not only absorbs sounds when stepping on the floor, but also plays a role in the sound insulation of different floors. In addition, the super solid wood flooring can also bring new solid wood hearing. The new wood fiber silencer system reduces indoor noise by half. 5, sound insulation blanket An acoustic blanket can be used as a solution to pipeline noise. Cut the soundproofing blanket into 100mm wide strips, apply the glue on one side, spirally wrap it around the sewage pipe as the first layer, then wrap the soundproof material in one layer, and spirally wrap the outer layer with sound absorption. Sound insulation blanket, this method solves the pipeline noise very thoroughly.
