It is cleaned with a soft dry and damp cloth to wipe dust and small stains. You can wash it with soapy water. Unsaturated resin paints should be protected against gravity bumps and impacts. Nitrocellulose paint should prevent sharp objects from scratching the paint film and do not place overheated cups.
In addition, it should be noted that solid wood furniture is in an environment that is too humid or too dry for a long time. It will expand and deform after damp, and will cause loose structure after shrinking. Therefore, it is necessary to prevent excessive moisture in furniture and prevent dehydration caused by prolonged wind and sun exposure. Cracked.
Noise barriers are mainly used for sound insulation and noise reduction of highways, expressways, elevated composite roads and other noise sources. Inserting a facility between the sound source and the receiver makes the sound wave propagation have a significant additional attenuation, thus weakening the noise influence in a certain area where the receiver is located. Such a facility is called a sound barrier. It is divided into traffic noise barriers, equipment noise attenuation noise barriers, industrial boundary noise barriers, and highways and expressways, where various types of noise barriers are most used.
