 Polycarbonate panels has the characteristics of 
 1, the maximum impact force of the impact resistance --- polycarbonate panels can be achieved 3kg/cm specific gravity of 1.34g/cm 3, which is 200 times that of ordinary glass, 8 times stronger than acrylic plate, and almost no risk of fracture. 
 2, transparency --- lighting excellent light transmission rate of up to 75 to 89 percent, while its transparency comparable with the glass. 
 Weathering --- surface UV dose (UV) UV-absorbing, and converted into visible light, outdoor guaranteed for decades without fading. 
 4, the flame resistance --- polycarbonate panels are not spontaneous combustion and have the self-extinguishing. 
 5, heat, cold - in the test range of minus 30 ° C to 130 ° C, does not cause the quality change of deformation. 

 correct installation of the pc / frp Langban 
 First, the wave-type selection 
 1 PC / frp Langban lighting with approximation to the PC / frp Langban the color plate specification model. 
 2, such as PC / frp Langban skylights, PC / the frp Langban with color plate specification model. 
 Note: ① The purlins span is too large, may cause the PC / frp wave board warpage, caused by leakage. 
 ② recommended that the selection of the thickness of 1mm - 3mm above. 
 Second, the purlin span 
 Third, lap 
 1, the side lap ordinary color plates 
 Recommend the PC / frp Langban take the top of the steel tile board in the PC / frp wave pressure bar pressure available stainless steel, aluminum or color plate. Layering width of about 30mm, vertical ribbed better thickness ≥ 0.5 mm, lap joints and supporting Porto better. 
 2, the sandwich composite Langban 
 If overlap and sandwich composite Corrugated Sheet, screws fixed at plus supporting Porto, in order to better fixed the PC / frp lighting board. 
 3, the sandwich plate 
 Overlap, such as PC / the frp Langban with sandwich flat panel foam gouged out of the sandwich plate lap joints, the PC / frp trapezoidal wave of negative to positive take. 
 4, longitudinal lap 
 General requirements for vertical overlap length> 300mm, such as PC / the frp Langban and color plate wave inconsistent, the lap length should be> 500mm 
 Fourth, the fixed 
 A fixed nail head diameter than the screw shank diameter 1.5 times or more, and be waterproof glue, do not nailhead direct compression board, in order to reduce the pressure. 
 2, Do not screw too tight, or it may lead to stress, caused by the partial crack of the board. 
 3, waterproof glue and not the use of PVC pads, waterproof dressing or asphalt composition; sealant must be selected neutral glass, plastic, Do not use acidic gum. 
 4, the installation process can not be fixed at both ends to a fixed intermediate, should be fixed at one end and along the same direction, construction, otherwise it would cause the intermediate stress concentration, so that deformation or cracking. 
 5, due to the linear expansion coefficient of the PC / frp board than the metal material about six times larger, so, must the board first drilled hole, and only with self-tapping screws, and self-tapping screws must hit the aperture intermediate, or else Since the displacement and set aside the thermal expansion and contraction caused by lack of self-tapping screws around the PC / frp board cracks or board shrinkage deformation. 
 6, reserved for the calculation of the expansion space; expansion value = linear expansion coefficient of linear expansion coefficient × length × maximum temperature value of the PC / frp board = 7 × 10mm/mm / C such as: length 1000mm, PC / frp board such as day and night temperature difference of 30 ℃, then the Reserve space for expansion of at least 2.1mm above. For example, using Φ5mm self-tapping screws, PC Corrugated Sheet drilling diameter> 2.1mm +5 mm = 7.1mm. 
 , If in the Corrugated Sheet below to add a layer of the PC / frp flat panel or phototherapy watts, the fixed point of the lower PC / frp board must be added to the metal strips, otherwise PC / frp board sag caused by the weight of the PC / frp board, lead screw around the PC / frp flat panel cracks. 
 On the clean 
 Pc / the frp Langban surface dust, dirt generally will be clean, soft cloth or sponge dampened in a mild detergent and then rinse thoroughly with water. 
 Six, chemical corrosion 
 1, to prohibit the cement surface is not dry, acid and alkaline substances in surface contact. 
 To prohibit the benzene, gasoline, carbon tetrachloride, the day that water, turpentine and other organic solvents or glue containing such ingredients, paint contact
