Phenolic board phenolic board introduced the "King of insulation material" reputation, is a new generation of thermal insulation materials fire. Phenolic board has a lightweight, fire and met the fire is not burning, smoke-free, non-toxic, non-drip, surrounded by a wide operating temperature. At low temperatures does not shrink, not brittle characteristics. Because closed-cell high phenolic board, phenolic board the low thermal conductivity (can be less than 0.030w / mk), good insulation properties, and has a certain resistance to water and water vapor permeability, thermal insulation material is a better, more is ideal for HVAC engineering insulation. Since phenol having a benzene ring structure, dimensional stability, rate of change of <1%. And the chemical composition and stability, corrosion aging, especially the ability of organic solvents, acid, alkali corrosion. In the production process in the foam blowing agents do not have freon line with international environmental standards, and its molecular structure containing hydrogen, oxygen, carbon, when the pyrolysis gas spilled toxic, tasteless, the human body, are harmless to the environment, in line with the national environmental protection requirements. Therefore, phenolic board is ideal fire protection, thermal insulation, energy-saving, environmentally friendly and beautiful green insulation material. Phenolic board main technical parameters: bulk density 40-100kg / m3; 20-200mm thickness thermal conductivity 0.022-0.030w / mk flammability rating B1-A2 smoke density rating <5 Operating temperature -196 ~ + 200 ℃, however, the state of benzene board ambiguous attitude, Jilin Province issued the document allowed to use, and the price of benzene board and phenolic board hundred times more than the difference, so absolutely can not monopolize phenolic lignin modified phenolic insulation materials market is very good fire protection, fire test window made in Tianjin Fire in 1000 degree heat after 40 minutes found no combustion phenomenon, and phenolic board only surface carbonation, no burning, from the fire self-extinguishing, no shade burn combustion process releases less smoke, odorless, non-drip , the real solution has been exterior insulation and fireproof insulation board problem, is a revolution in the wall material. A large number of acquisition and utilization of plant stalks, will directly increase the income of farmers, to solve some of the rural surplus labor force, directly contributing to rural economic development in the long term to protect and improve people's livelihood is significant! Phenolic board architecture architecture consists of: an adhesive layer, insulating layer, wipe the surface layer, facing layer and accessories. Attributed to the adhesive layer for the construction, between the bottom and the surface layer is between the first and foremost with the cementitious material firmly bonded to the upper and lower layers, and its main source of inorganic filler. Insulation to prevent and reduce the heat loss to the environment turbine, steam turbine and insulation layer in the outer pipe laying endures, the main filler for wool fibers and a certain amount of organic matter, moisture, and adhesives. Facing layer should be used plasters, mortars and other decorative or functional coating lightweight breathable water outstanding exterior paint, so let the product maintains its lightweight characteristics, also increased its aesthetics. Phenolic board features ⒈ high flame retardant, low smoke. Oxygen index up to 56% less than 5.1200 ℃ tight does not burn, fire only carbide drip. ⒉ insulation, and low thermal conductivity. Phenolic board material is from the "closed little bubble" component, can form a good blocking temperature thermal convection. Its thermal conductivity is 0.02 ~ 0.03w / mk, achieve the purpose of saving energy. ⒊ weathering stability, high heat resistance. Phenolic foam insulation temperature is -60 ℃ ~ 150 ℃, dimensionally stable, non-absorbent, anti-aging, long service life. ⒋ CFC-free foam, non-toxic and tasteless, is a green building materials. Foaming process does not use CFCs, the ratio is reasonable, compound completely, forming no residual poison, no smell of acid and alkali, alkaline to acidic with good resistance.

Phenolic board waterproofing home should first explain the so-called waterproof phenolic board problem itself is divided into waterproof waterproofing problems and system problems. Phenolic board solve water problems mainly through the phenolic board to complete water treatment, water treatment vintage phenolic board is to spray water repellent to complete. And as technology continues to improve insulation materials companies, the new approach is waterproof phenolic board at the time of production, when thrown at high speed centrifuge phenolic board through the adhesive spray equipment and water repellent phenolic board, phenolic board get better water effects. Old-fashioned old-fashioned products due to the waterproof effect is not very easy to make an average of phenolic board on the wall in the insulation system impossible to achieve less than 25 years of life requirements. The new water treatment can be fully compliant. Phenolic insulation board waterproofing system is more complex, factors that could shadow phenolic board insulation system under normal circumstances waterproof performance is as follows: 1. The quality of the wall of the base surface water interface agent; 2. phenolic board itself is waterproof interface agent treatment effect ; 3. used wiping mortar surface hydrophobic; sash 4. buildings, air holes, etc. The details of the parapet waterproof enhancement processing;
