Beijing Dragon International Co., Ltd. is a Chinese professional solar panels PC sheet manufacturing enterprises, but also the only one in North China solar panels and polycarbonate panels professional manufacturers, the company is located in Daxing District, Zhuang Industrial Zone, Beijing Dragon International sunshine board now has advanced professional several PC sheet production line, using the German Bayer (BAYER) and U.S. General (GE) and other countries a PC polymer materials and UV UV resistant polycarbonate material, with the company's senior management ten years valuable experience, products and technologies have reached the international advanced level, the production of PC polycarbonate series hollow sheet, solid sheet, profiles and other products sold nationwide, and was selected as the opening ceremony of the Beijing Olympic Games "Olympic history scroll" center plate, successfully hold the dream of the whole of China and hope. Beijing Dragon International solar panels line the newly introduced this technology is more advanced, more versatile products. Now producing sheet thickness 4MM to 50MM, has been developed from the original to the multi-layer board, hollow sheet etc., not only impact resistance, sound insulation, heat insulation, flame retardant, anti-aging characteristics enhanced category more quality and more gifted, and higher technological content, usability, overall performance stronger, wider application areas (for example, can be directly used as proof core doors, windows, etc.), may play a role in many areas. Put into mass production, the annual production capacity of up to 8,000 tons, and China with its unique advantages to fill gaps. Welcome to Beijing Dragon International Limited sunshine board inspection! Sunshine board manufacturers: 18800089369 QQ: 2811046909 Sales Center Manager: Nijing Li double sun panels, three solar panels, four solar panels, meters fonts sun panels, well shaped roof solar panels solar panels intermediate purlin spacing of 1.05 for the Best, beam width determined according to the thickness, generally is 1.4-3 m. High-end solar panels uses a unique surface treatment technology, can resist the sun's ultraviolet rays spread destruction will not fade, does not fade, not because of the weather factors that reduce the intensity. Sunshine board is an excellent overall performance engineering plastics with excellent physical, mechanical, electrical and thermal properties, and therefore polycarbonate sun panels are "transparent plastic king" reputation, it has good impact resistance, heat insulation, noise, lighting, UV, flame retardant, etc., sun board combustion properties of flame retardant B1 level. Solar panels are widely used in public, civil and files canopy lighting, channel roof, elevated road noise walls, malls roof, greenhouse plants, is the world's best shed a light material, is widely respected modern architectural decoration industry and praise the latest generation of products. I. Project Overview sun panel polycarbonate panels Installation Precautions plate mounting recommendations: 1. Installation must be kept smooth and clean skeleton; 2 check sheet cut size and expansion allowance is qualified, leaving enough to pay special attention to uniform expansion gap is calculated as follows: Total expansion gap = expansion coefficient × local maximum temperature difference before and after mounting the sheet length × thermal expansion coefficient of 7.0 × 10-5mm/mm.K 3. plates different thermal expansion coefficients of the supporting frame and the need to leave headroom to withstand wind pressure, snow load, etc., so the amount to be set aside to fully embedded, as well as thermal expansion and contraction of space. General sheet edges into the fixed frame 25mm or more, and at least two of ribs when installing fixed area; thermal expansion general gap of 3mm per meter; 4. Identify UV plate surface side, and to the outer mounting face never allow the inward side of the UV installation; 5 when installing sheet metal, sheet metal cover on the protective film and sheet will affect the combination of fillers, so before installing the protective film around the plate lift 5 ~ 10cm, do not let the profiles grip protective film, but can not lift too much, so as to avoid damage due to operation of the board; Note: Some workers to operate when the protective film clip in the profile, and then printed with a sharp tool and then lift plan , but often scratch the plate surface damage resulting sheet; 6. hollow sheet cold mounting case, the bending radius of not less than 175 times the sheet thickness; 7. hollow sheet only along the curved ribs; 8. hollow sheet tilt should be installed along the rib, which is favorable condensate export; 9 as be fixed directly to the board self drilling screws, be reaming, all hole diameter should be greater than the bolt diameter, leaving a gap thermal expansion and contraction; Therefore, in steel plate hole, the aperture to be 50% larger than the screw diameter, at the bend to avoid locking screw to avoid split board; 10 self-tapping screw tightening when the force should be uniform to ensure that the real profile sealing strip and plate compactors ; 11 All voids should be filled with a neutral sealant, neutral sealant and adhesive coating exposed parts to prevent the penetration of cleaner edges and prevent gradual cracks; When they find installation defects, leakage may occur in parts can be sealant compensate. Choose to use after curing sealant remains soft, low modulus, elongation is greater than 50% neutral weathering silicone rubber, glue and aluminum front plate to make sure surface is clean and dry, so that no grease, dust , water vapor, dew, and other debris, sizing should be uniform, smooth surface layer, and may not have the same cross-section dimensions intermittent phenomenon; pay special attention to the use of neutral sealant must be made in advance with the board compatibility test, in order to avoid chemical reaction with the plates; 12. hole center to the edge of the plate spacing should be greater than or equal 5cm; 13. Sheet whole process of installation is prohibited foot pedal surface, the operation shall be used across the board can be moved pedal; 14.PC board Always cut length greater than the width before bending; 15. plates immediately after installation requirements torn off the protective film, as a result of construction of special requirements to protect the board also must first torn off protective film, then re-cover; 16. plates after installation should self-test, in particular, should conscientiously do spray test, check for leaks and, if leakage hazard should be eliminated, and then check the quality of appearance.
