powder coating keep safe

Building energy conservation is an important part of the work of energy-saving emission reduction, is the common responsibility of all Chinese people, with building areas of new materials, new 

technologies continue to emerge, and construction of energy-efficient propulsion, civil buildings are widely used all kinds of thermosetting insulation materials, in improving the building work 

and economic value and social benefits at the same time, buried under the fire hazard. Thermal insulation materials in the thermal insulation material to become the culprit of the fire accident, but also deeply affect the degree of fire accident. Under the precondition of achieving the wall energy saving target, promote the construction of external wall insulation technology, determine the specific objectives of the fire prevention work, and constantly enhance the flame retardancy of powder coating, take appropriate fire safety measures become effective prevention and containment of exterior wall thermal insulation material fire accident of priority.

Powder coatings mainly have the following characteristics: high flame retardant, low smoke. The oxygen index is 56%, and the smoke density is less than 5. 1200 C does not burn, fire only no 

dripping carbonization. Good insulation, low thermal conductivity. Phenolic foam material is made up of "closed type small bubbles", which can block the heat convection of the temperature. Its 

thermal conductivity is 0.02~0.03w/mk, which can achieve the purpose of saving energy. Weather resistance and high heat resistance. Powder coating temperature is -60 C ~150 C, stable 

size, non absorbent, anti-aging, long service life. Fluorine free foaming, non-toxic and tasteless, is a green environmental protection building materials. Foaming process without the use of CFCs, reasonable ratio, the reaction is complete, and the formation of compounds no toxic residue, no any smell, acid and alkali resistant, for alkaline acid has good resistance.

Although China's current production of PF as compared with foreign countries, in the technology and construction application still exist certain disparity, but powder coating as a safe, green new energy-saving building materials, the utility model has the advantages of has been 

recognized more and more in the construction sector, and the Public Security Fire Department sources. Concern is that in recent years in our country, the relevant scientific research units and enterprises in the phenolic resin modified and foaming technology has the new breakthrough, one is to overcome the PF powder dregs, brittleness and low strength shortcoming; the second is cost of PF is more close to the PS; third is close to neutral pH value products, the metal without corrosion.
