Nowadays, the houses in cities are becoming more and more dense, the cars on the roads come and go, the noise is particularly noticeable, and even at night they can't sleep. Is there any way to eliminate noise pollution? In fact, you can install soundproof curtains that can not only play sound insulation Works, and can block the sun. What kind of material soundproof curtain is good? How to buy noiseproof curtain? First, what is the effect of soundproof curtains 1, soundproof curtains can prevent sound from entering the room from the gap in the curtain, can increase the sound transmission medium, reduce the decibels of the outside sound, and the indoor sound is not easily lost to the outdoors. 2. The soundproofing volume of soundproof curtains is generally in the range of 6-15 dB. The sound insulation curtains with different materials have different sound insulation effects, and the sound insulation effect is the best among the flocking curtains, which can absorb a little more noise and have excellent sound-absorbing effects. Second, what material soundproof curtains are good 1, chenille soundproof curtains Sennel material soundproof curtains are the best. Its biggest feature is that the suede is very plump and drape effect is good, and the chenille noiseproof curtain fabric is thick, giving a feeling of atmosphere. 2, flocking soundproof curtains This velvet insulated curtain is characterized by a special layer of coating on top and a thin fluff on the surface of the flocked acoustic curtain, which has sound-insulating effects. In addition, flocking soundproof curtains are very environmentally friendly and do not fade easily. 3, canvas soundproof curtains Compared with flocked soundproof curtains, canvas soundproof curtains have a slightly poorer aesthetic appearance, but canvas soundproof curtains have good sound insulation and can block general noise requirements. If the curtain budget is relatively low, canvas acoustic curtains are the best choice. 4, fiber material Compared with the curtains with the three materials in the front, the fiber curtains have a somewhat inferior sound insulation effect. Although the fiber curtains are relatively thick and can play a relatively good role in blocking light, the fiber curtain itself has many pores and the surface is not smooth enough. It can neither effectively absorb the noise nor reflect the sound waves back. Third, noise protection curtain purchase considerations 1. When choosing noise-proof curtains, we must not only understand the material of soundproof curtains, but also understand the production process of soundproof curtains and so on. Because everyone has different requirements for sound insulation, everyone should choose according to their actual situation when purchasing. 2, better soundproof curtains, its quality will be detected by the state, will not cause harm to the human body, so in the time of purchase, we must pay attention to check the quality of soundproof curtains. 3, the better the quality, the better its brand reputation, so when you buy the best choice of big brands, to avoid the purchase of poor sound insulation curtains. For example, Kang Ying, Jing Mei Jia, Xin Fei, and so on, are well-known big brands, we can refer to it. Editor's summary: The above is Xiaobian's introduction to soundproof curtains .

2.spring break device:
Sectional doors are hinged and they bend in the tracks as the door opens and closes. Many of these doors are counterbalanced with extension springs, also designated "stretch springs," and they have seven characteristics. The length is the measurement of all the coils pressed together. This, along with the inside diameter of the coils and wire size - the thickness of the wire from which the springs are made - determine the stretch, the distance the spring is extended - normally half the door height, and pull, the force the spring pulls when stretched its normal length. The type of ends determine how the ends of the spring are mounted. The initial tension is the percentage of pull needed to separate the coils. This is determined by the pitch with which the springs are wound. On sectional garage door springs this is normally 15 percent. For example a 100 pound pull spring requires 15 pounds of weight to separate the coils; when a door is open the two springs will support 15 pounds of door weight without any stretch.
Most extension springs are made of oil tempered wire. These are normally coated or painted. Some springs are made of galvanized wire.
