Q:What is the meaning of the bulk density of double-sided color steel polyurethane panels?: Double-sided color steel rigid polyurethane plate its bulk density of 35 ~ 40kg / m3, thermal conductivity: 0.018-0.023, low thermal conductivity, thermal performance.

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:Specification for thickness of steel - wool sandwich panel: Color steel rock wool sandwich panel specifications are: 950, 960, 1150 type, rock wool thickness is divided into: 50mm, 75mm, 100mm, 150mm

Q:Sided 0.8 thick stainless steel plate extruded board sandwich panels there are production: Good insulation or polyurethane

Q:How many years can the life of the sandwich panel: Inside the house for decades, top ten years

Q:Industrial building facades: Even the United States outside the wall panels, search Dalian, the official website of the United States chemical building materials.

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:Rock wool sandwich board standards which: Rock wool core material: the use of density of 120kg / m? rock block staggered laying, the fiber perpendicular to the sandwich plate on the upper and lower surfaces, and close contact to enrich the sandwich panel of the entire vertical and horizontal. The combination of rock wool and rock wool and the upper and lower steel plates through the high-strength foaming agent to form a whole, sophisticated production process to ensure that the high-density rockwool insulation and metal plate between the inner wall can produce poles Strong adhesion, so that the rock wool sandwich panel has a very good stiffness.

Q:What is the foam in the color steel foam sandwich panel?: EPS is the English abbreviation of the bubble; but now it is not easy to use fire, but fire or rock wool

Q:Introduction of foam sandwich panels: Foam sandwich panels beautiful appearance, bright color, the overall effect is good, it sets load, insulation, waterproof in one, and no secondary decoration, is a wide range of uses, especially in the construction site for temporary facilities such as office, Wall, etc., but also reflects the modern construction site of civilized construction, especially in the rapid installation and put into use, can be installed in the removable, material turnover index, there are obvious advantages, a substantial reduction in temporary construction site costs, Will be indispensable for new lightweight building materials.
