Q: Is the polyurethane sandwich panel and foam board flame retardant?: On the market, the polyurethane foam flame retardant grade B1, B2, B3 three grades. Because of the cost, sandwich board with the majority of polyurethane material is B3 level, a small amount of B2 level, there are a small amount of special requirements B1 level. B1 level for the 'flame'; B2 level for the 'combustible'; B3 level for the 'flammable'. B1 grade oxygen index requirements of more than 30%; B2 level requirements of more than 26%, 26% of the following collectively referred to as B3 level. You said the flame retardant, it should be self-extinguishing from the fire. B2, B1 from the heat certainly no problem. A little better B3 (oxygen index of about 25%) can also be self-extinguishing, but more than B2 self-extinguishing time more than a few seconds. General oxygen index of less than 24%, it is difficult to self-extinguishing from the fire, will always burn, the greater the greater the burning. The The Oxygen Index: The concentration of oxygen required to stabilize the combustion in the oxygen and nitrogen gas mixture under the specified shape of the foam, the specified source of fire and the size of the flame. - For example, the better the flame retardant properties of the foam, the higher the concentration of oxygen needed to ignite the foam, the higher the oxygen index of the bubble

Q: Build a color steel sandwich panel production plant how much money: The general machine price of 25 million or so, the venue costs plus how much raw materials you need, you can run the general about 100 million, but the funds to return to the fast, can not have too much debt.

Q: How about the sound insulation of the sandwich panel?: Insulation material does not have the same frequency of noise barrier effect is not the same, impermeable to prevent the snow from the inside into the Caigang sandwich panels. Snow is important to pass through the gap or node into the color steel sandwich panels. To achieve the performance of anti-seepage, the need to use the sealing ring in the screw seal after the adoption of hiding-type flow, the overlap in the board with a sealant or riveting solution. Because of the variety of metal sheet roofing, color steel sandwich panels from heavy public buildings to the plant, Caigang sandwich panels sound insulation to a sound insulation coefficient a. 8% annual increase in the progress of Caigang sandwich panels after the installation of the roof without access to the mouth, steel structure with energy saving, environmentally friendly recyclable, Caigang sandwich board confidence that few people can see on the spot.

Q: Color steel rock wool sandwich board price how much: The price by region, quality and demand to go, Tianjin is rock wool board manufacturers more cities, a single rock wool board, then many can do 40 or so per square meter

Q: anxious! Will the polyurethane sandwich panels of various parameters, plant design!: Polyurethane is a two-component AB material (isocyanate and combined polyether) mixed foam, is the thermal insulation material in the lowest thermal conductivity of 0.017 ~ 0.024 (thermal conductivity of the lower the better insulation). Polyurethane sandwich panels used in the filling process of polyurethane, pre-made pre-insulation board directly installed on-site use. If your plant area is relatively large, it is recommended that you only use the whole color plate, and then use the field of polyurethane spray foam process, this process than the infusion process is the advantage of spraying seamless, better insulation. The cost is still lower than the infusion process.

Q: Who knows the standard of color steel composite panels which? No matter what kind of material sandwich layer, please know the knowledge of this person told me.: "GB / T 23932-2009 Construction of metal surface insulation sandwich panels" This standard specifies the terminology and definitions, classification and marking, requirements, test methods, inspection rules, packaging, transportation and storage of metal surface insulation for sandwich panels (hereinafter referred to as sandwich panels). This standard applies to the industrial production of industrial and civil building facades, partitions, roofing, ceiling sandwich panels. Other sandwich panels can also be used with this standard. Since the implementation of this standard, JC689-1998 "metal surface polystyrene sandwich panels", JC / T868-2000 "metal surface hard polyurethane sandwich panels", JC / T869-2000 "metal surface rock wool, slag Cotton sandwich panels "abolished.

Q: Which color plate sandwich board price is low and good insulation: Polyurethane sandwich panel comprehensive performance is better. fair price. Tianfeng good

Q: Color steel polyurethane sandwich panels can do the paint room cut off you: Can be cut off, in the construction area with more, and the sound insulation and insulation effects are very good. Polyurethane material has excellent water resistance, steam barrier performance, material does not contain water, water absorption is very low, can well block the water and water vapor infiltration, the wall to maintain a good, stable adiabatic situation, is other insulation materials Difficult to achieve.

Q: 50mm thick roof color steel sandwich board price is generally how much money a m2?: 50mm thick roof sandwich board is generally 65 yuan per square main to see how thick you want the steel plate

Q: Foam sandwich board in line with the fire building requirements? There is no regulatory requirements in this area? I was in Jiangsu !! Thank you: Comparison of Common Composites and Their Comprehensive Performance. ???????????????????????????????? The new composite plate common metal surface sandwich panels, mortar surface steel sandwich panels, steel mesh sandwich panels, composite lightweight sandwich partition board, composite hollow prefabricated partition board, polystyrene foam mortar powder layer The The metal surface sandwich panel includes metal surface polystyrene sandwich panel, metal surface rigid polyurethane sandwich panel, metal surface rock wool (slag cotton) sandwich panel, single layer color steel rock wool sandwich aluminum thin composite board, Metal gypsum sandwich panels, metal gypsum rock wool sandwich panels. The author through the daily supervision of the relevant situation on the performance of the relevant metal surface composite sheet were a comprehensive comparison, see the following table: Through the above comparison can be seen: metal surface composite fire hazard mainly flammable, easy to melt dripping, high smoke, easy to lose the integrity of the metal surface rock wool (slag cotton) sandwich board fire resistance and combustion Performance can be, the insulation performance is acceptable, but the normal use of the firmness is not enough, the impact on the environment; metal gypsum sandwich panel is both fire and solid, but the insulation performance is poor, the price is more expensive; non-combustible hard Polyurethane metal sandwich panels are expensive.
