Construction industry with thermal insulation materials, fire resistance, direct impact on people's lives and property. Into the 21st century, frequent high-rise building fire, so how high-rise building fire safety, insulation, how to protect the environment, has become a worldwide problem, of environmental protection fire insulation materials, has become a research priority sectors. France and the Nordic construction sector, the experts believe that the existing bubble Plastic , Only the phenolic foam Plastic Has good fire resistance, the event fires burning releases toxic fumes in all foam is the smallest, environmental pollution is minimal. The former Soviet Union and Eastern Europe in public buildings has been widely used phenolic foam, Western Europe and the Middle East require all new priority projects to do with phenolic foam insulation, phenolic foam as France will be closed and control the fire material. In recent years, the Japanese began a large number of applications of phenolic foam, the Japanese Ministry of Construction promulgated "phenolic foam flame retardant as a standard building materials," the decree. Phenolic foam has many advantages, especially in the fire, toxicity, excellent performance has special: retardant, self-extinguishing, low smoke, flame penetration resistant, non-drip case of fire, toxic gases even micro, and oxygen index is generally 35 to 40, is the highest organic foam; good heat resistance, long-term use temperature is up to 130 ~ 150 , hard polyurethane foam than the high 30 ~ 40 ; thermal conductivity is generally 0.029 ~ 0.04W / m? K, close to the polyurethane rigid foam, better than the current widely used in the construction industry polystyrene foam. 1999 at the end, China Electric Apparatus Research Institute (formerly Guangzhou Electrical Apparatus Research Institute) to undertake the Guangzhou Science and Technology Commission key scientific and technological project --- a new phenolic foam materials, and the first in the country made continuous production of phenolic foam Formulation and Process of the technical route. The project more than two years of research, made two scientific research; phenolic foam molding technology and production Phenolic resin Low foaming machine, also obtained two patents, the successful production of phenolic foam composite products. Comprehensive coverage of the two patents continuous production of phenolic foam of new formulations, new technology and new equipment to fill the gap. 2002 8 months, China Electric Institute and Guangzhou China and Germany have signed a new material transfer agreement, and soon the company in Guangzhou China and Germany on the project into a product, to produce aluminum composite phenolic foam board, single-sided color steel composite foam board, and used to make into a central air conditioning duct insulation, steel roof, wall phenolic foam insulation materials and fire ventilation pipes and other products, sold at home and abroad. In 2003, the project won the Guangzhou Municipal Science and Technology Progress Award. February 8, 2009, the National Vice-Premier Li Keqiang, Guangzhou, China and Germany to visit our company, visited the production of phenolic foam products, and watched the fire performance of phenolic foam product testing, and asked the sales of phenolic foam products. We are high quality suppliers, our products such as China leather mens briefcase , leather laptop briefcase for oversee buyer. To know more, please visits briefcases on wheels.
