The Foam sandwich panel has developed rapidly in developed countries and has been widely used in construction, national defense, foreign trade, storage, energy, and other fields. Phenolic materials have accounted for 40% of the sound insulation and thermal insulation foam plastics used in the construction industry in the United States. Japan has established a phenolic foam popularization association to promote this new material. Do you know why everyone likes to use Phenolic board? Here are some answers.
Here is the content list:
The advantages of the Phenolic board are explained
The Phenolic board is developing rapidly and is widely used
The service temperature of the Fire insulation board is 196～+200℃, and it has the characteristics of no shrinkage and no embrittlement under a low-temperature environment. Since the Phenolic board is made of phenolic foam material, the phenolic foam has a high closed cell rate, low thermal conductivity (can be lower than 0.030w/MK), good thermal insulation performance, and certain water resistance and water vapor permeability. It is a good thermal insulation and energy-saving material, and it is an ideal thermal insulation material for HVAC projects. Since phenolic formaldehyde has a benzene ring structure, it is dimensionally stable with a change rate of <1%. And the chemical composition is stable, anti-corrosion, and anti-aging, especially the ability to resist the corrosion of organic solutions, strong acids, and weak alkalis. In the production process of foaming, Freon is not used as a foaming agent in line with international environmental protection standards, and its molecular structure contains hydrogen, oxygen, and carbon elements. When it is decomposed at high temperatures, the overflowing gas is non-toxic, tasteless, and harmless to the human body and the environment. In line with national green environmental protection requirements. Therefore, a phenolic super composite board is an ideal environmental protection green thermal insulation material with fire prevention, heat insulation, energy saving, and beautiful appearance.
Phenolic foam is internationally recognized as the most promising new type of thermal insulation material in buildings. Because this new material is fundamentally different from the usual polymer resins obtained by adding flame retardants. It will not burn, melt or emit toxic fumes in a fire. And it has the advantages of being lightweight, non-toxic, non-corrosive, heat preservation, energy saving, sound insulation, and low price. And no Freon foaming, no environmental pollution, good processability, and convenient construction, its comprehensive performance is unmatched by various insulation materials. The Phenolic board is generally used for the insulation of central air-conditioning systems in high-end and high-rise buildings such as hotels, apartments, and hospitals. Most of the central air-conditioning systems in high-end buildings in Hong Kong have switched to phenolic foam materials. The Refractory phenolic foam board has indisputable comprehensive advantages for cold storage, cold storage, and thermal insulation for industrial pipes and equipment such as the petrochemical industry, building partition walls, exterior wall composite panels, suspended ceilings, sound-absorbing panels, etc. It solves the problem of other organic materials The fire performance is not ideal. Inorganic materials have a high water absorption rate, easy "condensation", skin itching during construction, and other problems. They are the third-generation best thermal insulation materials for air-conditioning systems and various electrical appliances.
