GFK antibacterial board is a new type of high-strength energy-saving board made of fiber, flame-retardant resin, aluminum hydroxide and other materials, produced by special ultraviolet light chemical reaction, and made by nano-treatment process on the mold surface. GFK antibacterial board has the characteristics of ordinary building board polyurethane board, and also has many characteristics that other metal and non-metal building materials do not have.
It is promoted as a new energy-saving material in Europe and is widely used in the construction industry, aerospace, wind power generation, new energy vehicles, medical equipment and mine crawler transportation.
As a new type of high-strength and high-energy-saving building board, GFK antibacterial board has the following characteristics:
Replacing polystyrene and polyurethane sandwich panels, it will not produce white and other pollution generated by polystyrene and polyurethane sandwich panels after fire or scrapping, reducing environmental pollution. It is an environmentally friendly product. Garbage thermal power stations are happy to recycle this type of waste as raw materials for power generation.
GFK antibacterial board has excellent chemical stability and is inert to acids, alkalis, salts, and oxidants. For example, it does not blister, bulge, or powder in 100C concentrated phosphoric acid, hydrochloric acid, sulfuric acid, and their salt solutions. It is stable and is widely used to replace metal and aluminum products in marine vessels.
GFK antibacterial board has a density of 1.75 g/cm3, and a 2MM flat board weighs about 4.2 kg per square meter. It has very good mechanical properties, high elasticity, high impact resistance, and very good static force value under large amplitude. It has a small linear thermal expansion coefficient. According to DIN EN 356 test, the impact strength can reach 55 KJ/㎡, the bending strength is 65 Mpa, and the shrinkage rate is 0.03%.
Imported silver ions are added to the raw materials of GFK antibacterial board, and the GFK antibacterial board with added silver ions effectively kills bacteria. The antibacterial and fungal rate is tested to be over 99.9%. Mildew is caused by moisture or dirt. After testing, the water absorption rate of GFK board is only 0.013%, and there will be no moisture conditions. Its surface is smooth and dense and will not condense dirt. In this way, it can achieve an effective mildew-proof effect. After multiple tests and tests by the national authorized testing center, "Aspergillus niger ATTCC9642, Rope-shaped green plum ATCC11797, Chaetomium globosum ATCC6205, Green Gluecotomyces ATCC9645&q...
GFK antibacterial board products are tested for formaldehyde content by the national authorized testing center using the "steam distillation method". The testing instrument UV-YIS MQ=20mg/kg. The test result is N.D (not contained).
The raw materials of GFK antibacterial board are all made of pure natural green materials, with a molding temperature of 150 degrees and a solid rest degree of more than 99.9%, so there will be no volatilization of harmful substances. The national authorized testing center refers to USEPA3052:1996 digestion method to process samples and uses LCP measurement for quantitative measurement. (LUSEPA6010C:2007) detection, lead, cadmium, mercury, refer to USEPA3540:1996 to process samples. GC-MS measurement (LUSEPA8270D:2007) detects ten items of polybrominated biphenyls (PBBS). All ten items of polybrominated biphenyls (PBOES) are far higher than the national safety standards. For details, see the...
After 1000 hours of destructive anti-ultraviolet aging test (equivalent to 30 years of outdoor exposure), there is no cracking, bulging, or powdering, and it can completely isolate ultraviolet rays.
The surface of the GFK antibacterial board is made by nano-treatment technology through the mold. The surface is smooth and dense. There are no tiny honeycomb pinholes when magnified. It is not easy to adhere to dust and penetrate liquid. The surface can be directly washed with water; its surface hardness is relatively high, and the maximum Bacol hardness can reach 70, and the surface is not easy to be scratched.
A large amount of aluminum hydroxide is added to the raw materials of GFK antibacterial board. In the event of a major fire, the combustion products are only water, carbon dioxide, carbon monoxide and dust, without toxic gases such as nitrogen compounds, sulfides, halogens, heavy metals, etc. The toxicity is less than that of pine wood combustion, and there is no burning dripping.
GFK antibacterial board has been improved. On the premise of reducing organic components, a large amount of environmentally friendly flame retardants have been added. According to the test of "National Fireproof Building Materials Quality Supervision and Inspection Center", its combustion value-added rate index is 50; the total calorific value of combustion is 2.7; the smoke generation rate index is 10 without burning falling objects, and the fire protection level reaches A and A2.
The thermal conductivity is low, and the heat loss is small. The thermal conductivity refers to the heat transferred through an area of 1 square meter in 1 second under stable heat transfer conditions, when the temperature difference between the two surfaces of a 1m thick material is 1 degree (K, C). It is expressed by λ, and the unit is watt/(meter·degree), w/(m·k). (The thermal conductivity of GFK antibacterial board is 0.073W (m·K), which is very low compared to metal materials. As we all know, metal is a good conductor of heat, among which the thermal conductivity of aluminum is 237W/(m·K), and the thermal conductivity of iron is 80W/(m·K). We know that the lower the thermal conductivity...
It can completely replace color steel tiles, polystyrene sandwich panels, polyurethane sandwich panels and other steel plates, saving a large amount of steel and mineral resources for the country, and saving coal, electricity and other energy used in steelmaking.
