A fire are thermoset phenolic foam board insulation, fire does not burn, does not shrink, no distortion, no drip, does not have a flame propagation. Phenolic board its high level of flame, fire performance, with only one fire burning carbide layer is formed on its surface, burning, distortion does not occur. Compared to the commonly used insulation materials, the biggest advantage is flame retardant, high temperature dimensional stability, no shrinkage, no melt drip, anti-flame penetration. It can be made into wall insulation board, shell and all kinds of special products, a lightweight construction and convenient. Phenolic board has the following advantages: first, safety, excellent smoke-free, non-toxic, fire performance. The second effect is good insulation, thermal conductivity between 0.022 to 0.3. The third is that it has good air permeability, permeability in buildings is important, breathable material used in construction, the mist and frost will not produce the phenomenon. The fourth is its environmental performance, the material can be recycled, not cause secondary pollution. Phenolic board is a new flame retardant, low smoke and fire insulation materials, thermal conductivity is only 0.023W / mk or so, the most prominent feature is flame retardant, low smoke, high temperature rambling. Phenolic board can be made wall insulation board, shell and all kinds of special products, a lightweight construction and convenient. Phenolic board widely used, it is suitable for large cold storage, storage tanks, ships and a variety of pipe insulation and construction. If used in fire demanding factories, mines and machinery and equipment, to better highlight its flame retardant, low smoke, high temperature rambling characteristics. Such as: ships, ships, trains, armored vehicles, insulation and paper, chemical, pharmaceutical and other areas. Phenolic Board Applications: Because polystyrene foam and polyurethane foam are flammable, not high temperature, in some industrialized countries, were being restricted fire department, fire safety demanding places, government departments have been expressly provided only with Phenolic insulation board sandwich board and its phenolic board. Thus, phenolic board insulation board is more suitable for high-performance materials have under demanding environmental conditions, and has good prospects for development. Other needs such as fire insulation requirements of the building steel plants, large industrial plants, activities room, cold storage, clean shop, building and floor, temporary housing, stadiums, supermarkets. Phenolic board Description: Phenolic board often referred to as phenolic board. Phenolic board is a phenolic resin and flame retardant, smoke suppressant, curing agents, blowing agents, and other additives, and other substances, closed-cell rigid foam made by scientific formula. Phenolic board excellent performance: 1, excellent fire performance: polyurethane and polystyrene insulation and other organic materials, combustion will produce smoke and toxic, easy to cause death, but also increase the difficulty of the fire. The phenolic board insulation board in a fire burn, burn up to A-level performance, maximum use temperature of 180 ℃ (allows instantaneous 250 ℃), 100 mm thick phenolic board insulation board anti-flame capacity of up to 1 hour or more without being penetrated . Carbon has a knot under the direct effect of the flame, no drip, no curling, no melting phenomenon, the surface layer of the foam structure "graphite foam" layer after layer to effectively protect the flame burning. 2, excellent thermal insulation properties: low thermal conductivity (<0.025W / m × K, more than twice as polystyrene, polyurethane similar), for thermal insulation of fine materials; 3, anti-corrosion anti-aging: virtually resistant to all inorganic acids, organic acids, organic solvents erosion. Long-term exposure to sunlight, no significant aging phenomenon, which has good resistance to aging; 4, low density, light weight: the density phenolic board material for 80㎏ / m3 or less, up to about 50 kg / m3. Reduce the weight of the building, reducing the load of the building, reducing the cost structure, and the construction is simple, fast, can improve work efficiency; 5, acoustic performance: phenolic board insulation board has excellent sound absorption performance, open-cell foam structure more conducive to the sound absorption; 6, environmental protection: rock wool, glass wool on the environment and people hurt, polyurethane, phenolic board will decompose cyanide, carbon monoxide and other toxic gases when burning polystyrene heat. The phenolic foam board with CFC-free technology, no fiber, in line with national and international environmental requirements. Phenolic board main technical parameters: (when 50 ℃) density 30-80kg / m3 thermal conductivity 0.024w / mk (24 ℃ when) 0.028w / mk 0.034w / mk (100 ℃ when) the temperature range -160 ℃ -190 ℃ Dimensions degree of stability and a linear variation <0.32% (70 ℃ 24h) <1% (70 ℃ 100% RH7 days) Water absorption <2% (by volume 75mm3, soak for 24 hours) 6.6 Oxygen index 54 smoke density horizontal and vertical burning combustion 60s 10s anti compressive strength parallel to 170Kpa (30kg / m3 when) perpendicular to 100 Kpa (30kg / m3 when) the anti-inflation strength parallel to 270Kpa (30kg / m3 when) perpendicular to 200 Kpa (30kg / m3 when) the lateral bending strength 170Kpa (30kg / When m3) Longitudinal 150 Kpa (30kg / m3 when) phenolic board insulation is often referred to as phenolic board. Phenolic board is a phenolic resin and flame retardant, smoke suppressant, curing agents, blowing agents, and other additives, and other substances, closed-cell rigid foam made by scientific formula. 1, has a uniform closed cell structure, low thermal conductivity, good insulation properties, polyurethane rather better than polystyrene foam; 2, under the direct action of the flame has a knot carbon, no drip, no curling, no melted phenomenon, the surface layer of the flame burning "graphite foam" layer and effectively protect the foam structure within the layer, anti-flame penetration time of up to 1 hour; 3, large temperature range suitable for the short term in -200 ℃ ~ 4, the phenolic molecules containing only carbon, oxygen atom, by pyrolysis; at 200 ℃ use, long-term use at 140 ℃ ~ 160 ℃, than polystyrene foam (80 ℃) and polyurethane foam (110 ℃) , in addition to small amounts of CO gas, but will not produce other toxic gases, smoke density maximum of 5.0%. 25mm thick phenolic plate board after being subjected to 1500 ℃ flame spray 10min, only a slight carbonation but not burning surface wear, neither fire nor will emit smoke and toxic gases; 5, phenolic board may be in addition to alkali corrosion In addition, virtually all resistant to inorganic acids, organic acids, corrosion of the organic solvent. Long-term exposure to sunlight, no significant aging phenomenon, which has good resistance to aging; 6, has a good closed-cell structure, low water absorption, anti-vapor infiltration, when used as insulation purposes (cold), condensation does not occur; 7, dimensional stability, low rate of change in the operating temperature range of the dimensional change of less than 4%; 8, low cost phenol board, only about two-thirds of the polyurethane foam. Application forms phenolic board: 1, producing a large piece of foam, and then use a computer program to control the copying EDM cut into various foam insulation sheet or tube shell functions as a thermal insulation, fire protection and decorative features and applies various occasions; 2, the direct production costs veneer sheet or large plate, decorative plates for the building or firewall, fire board and fire wall; 3, scene pouring foam, pourable large outdoor tanks below 15 ℃, reactor and pipes insulation; 4, scene spray foam with spray gun mines, tunnels and underground construction insulation layer surface do; 5, can be used as external wall insulation materials and internal and external steel sandwich board core.
