Phenolic plate volume density

by:Ventech     2020-12-08
Volume density refers to the volume of material and quality. Phenolic plate is a new kind of non-combustible low smoke, fire insulation materials, it is made of phenolic resin in foaming agent, curing agent and other additives made of closed-cell rigid foam. It is the most prominent feature of non-combustible, low smoke, resistance to high temperature of different change. It overcomes the original type foam thermal insulation material inflammable, cigarettes, drawback of the metabolic that encounter heat, retained the original type foam thermal insulation material is qualitative light, construction is convenient wait for a characteristic. Traditional phenolic board not only can be used for exterior insulation system, can be also prepared to act the role of surface composite insulation decoration plate, can also be used to build the traditional EPS/XPS exterior wall thermal insulation system fire belt/PU, will be used for fire prevention in the curtain wall thermal insulation materials, fire door insulation materials, as well as low or high temperature of fire insulation material. The volume weight of the insulation board is commonly: how many kilos per cubic meter of insulation board. For example, bulk weight is 15 kg plate was 15 kilos per cubic meter. Exterior phenolic plate in line with the Ministry of Public Security and the housing ministry of construction of external thermal insulation system for civil building fire protection requirements. The utility model applies to new multilayer, high-level building energy-saving construction and energy-saving transformation of old buildings. Curtain wall and curtain wall building energy efficiency. No water absorption, 24 hours soak bibulous rate is less than 3%. Permeability is insulation layer can prolong the service life of the wall. Heat preservation effect is good, low thermal conductivity, 0. 029-0. 029, energy saving can reach 50% ~ 65%. Can be used as a firebreak, exterior wall thermal insulation decorative sheet, has the characteristics of high flame retardants. Good stability and weather resistance is strong, not easy to shrink, don't break. Light quality, non-toxic tasteless, green environmental protection. Specifications meet the design requirements, density and thickness. Act phenolic construction method of external wall insulation board commonly adopt the method of binding mortar bond or with nails. Starting from bottom to top, from the beginning of the supporting position, with polymer glue on the cracking mortar, paste phenolic board on the wall. Bonded area should be greater than 35%, the first layer should be greater than 50%. Covering the heavier, nail should be on every square metre is 4 to 6 bar. According to the design requirements,
north of the Yellow River phenolic plate thickness and density should not be less than 4 cm, 50 kgm3 cold areas should be more appropriate. Phenolic plate is a new kind of non-combustible low smoke, fire insulation materials, it is made of phenolic resin in foaming agent, curing agent and other additives made of closed-cell rigid foam. It is the most prominent feature of non-combustible, low smoke, resistance to high temperature of different change. It overcomes the original type foam thermal insulation material inflammable, cigarettes, drawback of the metabolic that encounter heat, retained the original type foam thermal insulation material is qualitative light, construction is convenient wait for a characteristic.
