Car, train and airport noise of toilet partition maintenance company belong to low-frequency noise. Insulating glass on the third floor of Liaoning toilet partition is not the most ideal choice of insulating glass, but the combination of laminated glass and insulating glass should be selected to be the most ideal one. No matter low-frequency noise or medium and high-frequency noise of Liaoning toilet partition maintenance company, this kind of laminated glass is added Empty combination is the most perfect, the industry people call this kind of glass laminated hollow glass.
During manufacturing, the actual hole size and painting size shall be checked on the spot, and the manufacturing scale shall be determined on the premise that the standard allows. Inspect the aluminum alloy door and window products according to the standard.
Before the installation, check the openings of aluminum alloy doors and windows one by one, and provide written materials to the civil engineering painting team, and control the gap between the opening painting scale and aluminum alloy door and window frame at 15mm.
First, compared with the ventilation, the flat opening and overhanging is another opening way of the flat opening window, which makes the air in the room circulate naturally with the nature, and the indoor air is fresh. At the same time, the possibility of rainwater entering the room is eliminated, so the ventilation is good. Push and pull windows make the room naturally circulate with the air of nature, and the indoor air is fresh, but the possibility of rainwater entering the room cannot be excluded, and the ventilation is good.
Lowe glass is also called coated glass. Coated glass is coated with one or more layers of metal, alloy or metal compound films on the surface of the glass to change the optical properties of the glass and meet some specific requirements. The product has a high transmittance to visible light, a high reflectivity to infrared ray and a good thermal insulation performance. It is mainly used in construction, automobiles, ships and other vehicles Due to the poor strength of the film, it is generally made into hollow glass for use.
Fourth, the cleaning effect of flat window simple operation linkage handle, can make the window sash outside to indoor. It is convenient and safe to clean the outer surface of windows. The glass beads of sliding windows are all facing indoor, and the glass is easy to be replaced due to damage. It is difficult to clean the external surface of the window, especially the overlapping part after the window is opened.
In the plan, the selection of materials is clear: aluminum alloy profiles are selected from Wuxi Jinxiu company, sliding doors are selected from 828 series profiles (to increase wind resistance capacity and increase light opening), and swing doors and windows are selected from 50 series profiles. Foaming agent selection of high-quality sophisticated products. Neutral silica gel is selected.
7. Bridge cutoff aluminum waterproof function. The structure drainage system is designed by using the principle of pressure balance, the sliding slope is designed as a ladder type, and the drainage outlet is set, the drainage is smooth, and the water tightness is good. There are many ways to open the aluminum bridge, comfortable and durable.
Compared with the insulating glass window, the laminated insulating glass window is more obvious in the treatment of low-frequency noise, and can prevent the noise pollution caused by the resonance of the window caused by low-frequency noise. Laminated insulating glass window is a kind of sound insulation window with good sound insulation effect and mature production technology. Compared with other glass, laminated glass has the performance of shock resistance, anti-theft, bullet proof and explosion-proof. The glass of bank window is laminated glass.
