Acoustic doors and windows to buy skills
Acoustic doors and windows to buy the skills: The further acceleration of urban construction will inevitably increase the level of noise pollution. In particular, traffic noise accounts for as much as 40% of urban noise. Many urban residents who accompany the road day and night are naturally "unforgettable." The intensity of the noise can be expressed in sound levels in decibels (dB). The noise level is between 3O and 40dB. It is a quiet and normal environment; more than 50dB will affect sleep and rest; 70dB or more interfere with the conversation, causing upsets, lack of concentration; long-term work or living in a noise environment above 90dB. , will seriously affect the hearing and lead to cardiovascular disease and other diseases. At the same time, noise can also produce psychological effects. Under high-frequency noise, most people are uneasy and excited. Living in a high-noise environment for a long period of time can easily lead to irritability and sluggishness and affect work efficiency. Although the Government has taken a number of measures to rectify urban noise pollution, which has to some extent alleviated the noise problem, many people are still not satisfied. Pursuing a quieter living environment, choosing some effective sound insulation materials and "arming your own house" has become a concern of many citizens. The sound insulation performance of the plastic window, window, and window is determined by the degree of closeness between the two windows and between the window and the window frame. The opening window depends on the degree of closeness between the closed window and the frame. The steel doors and windows are generally made of rubber strips. Sealing, unlike ordinary aluminum alloy windows, is different from the "hard and hard", sound insulation effect is more obvious. At present, the styles of steel doors and windows are varied. In addition to the traditional internal and external swing, push-pull, and fold-out, there are also flat-hanging hanging windows and doors, push-pull upper hanging windows, and push-pull underhanging doors and windows. In terms of color, the common steel doors and windows on the market are mostly white, because the weather resistance and light stability of white or gray PVC profiles are good, but there are also color profiles, and the decorative design has more free space to play and more personalized. Although the price is higher, the market potential is still huge. Plastic doors and windows have good sealing performance and ensure soundproofing. But at the same time it also brings weaknesses in insufficient air circulation. In response to this situation, manufacturers have developed a ventilator that is used when closing a window, which does not affect sound insulation but also ensures the exchange of indoor and outdoor air. Ventilators can be installed between windows and window lines and do not take up space. Prices range from 1,000 yuan to 6,000 yuan, depending on the quality and specifications. If you want to switch windows regularly, you can choose the new timer automatic switch on the market. Its price is about 2,000 yuan. In the large building materials center such as Mercure can be glimpsed. The prices of steel doors and windows in the market are mixed. Plastic steel windows are as cheap as three or two hundred square meters, and imported products can cost more than 1,000 yuan. The prices of steel doors are also quite different, ranging from a few hundred to three thousand dollars. The new type of aluminum doors and windows are generally considered that the soundproof effect of aluminum doors and windows is not good, but in fact, the new aluminum doors and windows have made a great improvement in the sealing noise performance. The sound insulation performance of the window mainly lies in the sound insulation effect of the glass occupying about 80% of the area, followed by the sealing performance of the doors and windows. Some aluminum doors and windows products in the market are based on the principle of resonance transmission of acoustic waves and the use of different glass composite structures to enhance the sound insulation effect. In terms of hermeticity of the door and window structure, the use of high-quality plastic strips and plastic sealing accessories also solves the problem of poor sealing performance of aluminum doors and windows. The coloring ability of aluminum doors and windows is strong. After special processing, the effect of imitation wood grain and imitated granite can be made, so that the appearance of the doors and windows is more colorful and colorful, which suits people's different decoration requirements. Consumers can choose different grades and price products according to different practical requirements, and the price range is about 300 yuan to 1,000 yuan. Select sound insulation Insulating glass Insulating glass is composed of two or more layers of flat glass, and two or more pieces of glass are bonded to the aluminum alloy frame or the rubber strip with a high-strength, airtight composite adhesive, and the space between the sealing glass is set aside. Space, flush with inert gas for excellent thermal and acoustic insulation. Due to the poor heat transfer performance of air or gas trapped in the glass, superior sound insulation results. Hollow glass can also be placed in a different window grilles in the sandwich to make a special decorative effect. It is especially common in villa renovations. Laminated glass laminated glass refers to the PVB interlayer film sandwiched between two or more sheets of glass. PVB interlayer can reduce the amount of noise that penetrates the glass, reduce noise decibels, and achieve sound insulation. For example, laminated glass made of SAflex PVB plastic intermediate film can effectively block the common 1000-2000 Hz anastomosis noise. According to reports, "silent villas" have risen in foreign countries and are very popular. The use of laminated glass in foreign residences has accounted for a considerable proportion. Sound-absorbing decorative board Sound-absorbing decorative board is a new building material that combines sound absorption and decoration. It has excellent sound-absorbing properties and fire-retardant and fire-retardant effects. Generally, there are a variety of colors and pattern decorative cloths to choose from, and some products can also be processed into various shapes of sound-absorbing body according to design requirements.

They are inserted and removed by turning in one direction or another. Wood screws, floor screws, and sheet metal screws have flat heads that sit flush when holding material together. Machine screws fasten metal to metal and are inserted into a prethreaded hole or mated with a nut. Thread-cutting screws are self-tapping screws that cut away and remove the surrounding material to create a tapped hole. Deck screws resist rust and corrosion to hold outdoor decking materials together. Drywall screws have fine tips, coarse threads, and tapered bugle heads to penetrate drywall and grip wood without damaging material. Hex-head bolts, cap screws, and lag screws are driven with wrenches rather than screwdrivers or drill bits. Captive panel screws and thumb screws can be tightened and loosened without tools on parts that are frequently removed such as access panels. Screw caps can help to cover screw heads for both safety and aesthetic purp Carbon Steel Screw,Carbon Steel Screws Outside,Carbon Steel Screw For Sale,Carbon Steel Self Drilling Screws Taizhou TS HARDWARE Co., Ltd , https://www.shuwengroup.com
