When the size is smaller than the wavelength of the scattering body bellows, the incident light in a different wavelength components have different scattering, experimental and theoretical studies have shown that large rod horizontal bellows, is inversely proportional to the scattered light intensity and wavelength of incident light to the fourth. For example, the atmosphere in which small molecules and dust along pull, will produce significant scattering of sunlight, if there is no atmosphere, the air does not scatter light stainless steel bellows cheap, then the sky's background should be black, which is astronaut on the moon in the atmosphere outside and saw out of the scene. reason we see the bright sky in the day, is due to the scattering of sunlight by the atmosphere, while the light is scattered back from all these restrictions into our eye's sake . clear sky appear blue because of the short-wave components of white light scattering is strong, and thus in the direction away from direct sunlight, always blue-purple than red and yellow components of the composition to be more. while reason is the rising sun and sunsets bright red and that was the thickness of the atmosphere due to the evening sun dipped toward the ground, have experienced much thicker than noon, which was a lot of short-wave sunlight scattered along the original direction is one of the main long-wave components. compared , the noon sun direct ground, the thickness of the atmosphere through which the sun is thin, short-wave scattering does not sooner or later turn out. Tian Shi County winged eye and white. Hebei billion gold bellows compensator Manufacturing Co. a professional production of metal compensator a manufacturer, over the years has always been our customers love and trust! In order to allow customers in the market for ordering bellows devices have a simple understanding of the process, the staff analysis Hebei billion in gold a lot of customer case, summed up the data and information about the customer during the ordering process needs to be provided, There are optional compensator willingness friends can serve as a reference. Users in the selection of bellows when the following conditions must be clear: 1, path, connection type (flange connection, to take over the connection type) size when using the provided interface takes over the connection. If using special offer size or non-standard flange. Please specify the length of the installation length delivery restrictions. 2, working pressure compensator. 3, using the medium conditions (on the dusty, highly toxic, highly corrosive media in the selection please indicate so when making the choice of materials). 4, the operating temperature. 5, the offset amount (offset amount when determining the compensation amount is larger than actual). Under the above conditions are clear, according to the data series in the bellows parameter table to determine the product model. In addition, if customers have special requirements or need further advice, the best bellows further contact [] with sales or customer service staff | stainless steel bellows cheap | Welcome to Hebei million gold piping supplied by Hebei billion gold piping . Welcome to consult Hebei billion Gold Pipe Manufacturing Co. (www.yijinguanjian.com), be sure to specify when contact is through the "Business Alliance Member" see, thank you! Contact: Alan Li Tong
