Product description   Graphite polystyrene board   That graphite polystyrene board B1 grade graphite polystyrene board, known as the "black bubbles" or "blackboard", referred to SEPS, its called the B1 grade graphite molded polystyrene foam board.   Graphite polystyrene board performance:   Apparent density: 18 ~ 25kg / m3   Thermal conductivity: ≤0.032   Combustion performance: classification of B1 level (flame retardant)   Economy insulation anti-humidity weather resistance performance, belong to green products, widely used in construction, external wall insulation systems, especially those with fire safety requirements and requires the use of B1 grade polystyrene board exterior insulation works.   Graphite polystyrene board product features:   1, fireproof properties of flame retardant type B1 level: graphite polystyrene foam board combustion performance fully meet GB8624-1997 "burning of construction materials classification method performance" indicators B1 level, has a good fire resistance. With the Ministry of Public Security / Ministry of Housing and Urban public through word [2009] No. 46, "civil external facade insulation systems and fire Interim Provisions" requires the implementation of its scope of application will be more extensive.   2, insulation stronger: graphite polystyrene foam board is expanded polystyrene insulation materials further refined by chemical products, thermal insulation performance has been significantly improved. It contains special graphite particles that can reflect heat radiation like a mirror, and it contains can greatly enhance the thermal insulation properties of the infrared-absorbing material, thus reducing heat loss of the house. Its insulating capacity of at least 30% higher than the average EPS, help to improve energy efficiency and reduce carbon dioxide emissions.   3, the same effect is lower cost: outstanding insulating capacity of graphite Styrofoam plates in performance is particularly evident at low densities. Only need to use graphite polystyrene foam board insulation board can make 170kg of area 200 square meters, the insulation system reaches 0.032 W / (m • K) of low thermal conductivity. If using conventional EPS insulation board takes about 300kg, which is equivalent to 40% of the cost savings.   4, the construction is simple, system integrity, and consistent method of graphite insulation system polystyrene board insulation system with EPS thin plaster exterior, there is a higher system integrity and durability.   Executive Standard: Q / 12BJ 6032-2011   Physical and mechanical properties:   Project                                    Unit             Performance Apparent density                kg / m3            18 to 25 Compressive strength        kPa                   100 Thermal Conductivity       W / (m • K)          0.032 Dimensional stability             %                     0.3 Water vapor permeability  ng / (Pa.m.s)   Forty five Water absorption (by volume) %                   4.0 Tensile strength perpendicular to the board surface direction    MPa                0.10 Bending                                   mm                     20 Oxygen Index                            %                       32 Combustion rating         Reach GB 8624-2006 standard C-class   GB8624-2006 and GB8624-1997 "building materials and combustion classification" standard classification corresponds (Ministry of Public Security Fire Department public extinction [2007] No. 182):   1, according to GB8624-2006 testing determines that the class A1 and A2 level, which corresponds to the relevant norms and GB8624-1997 of the Class A;   2, according to GB8624-2006 testing determines that the class B and C, which corresponds to the relevant norms and GB8624-1997 the B1 level;   3, according to GB8624-2006 testing determines that the D class and E-class, which corresponds to the relevant norms and B2 level of GB8624-1997.   Packaging, transportation and storage   Products available plastic strapping or plastic film packaging, supply and demand can also be decided through mutual consultation.   In the transport and storage of fireworks is prohibited, not the weight or collision with sharp objects.   Products stored in a dry ventilated place, not long-term open-air exposure, away from the fire can not be brought into contact with chemicals.
