(1) light, high-strength
FRP profiles at the density of about 1.7, it is 4 ~ 5 times lighter than steel, and the strength is great, the tensile strength of 350 ~ 450MPa, close to ordinary carbon steel, the bending strength and bending modulus of 388MPa 20900MPa, which does not need steel reinforcement, "Beijing sanvoon sunshine" brand glass steel window after testing, wind resistance the properties of 5.3Kpa, more than the international standard GB/T7106 - 2002 in level 8.
(two) energy conservation and heat preservation
The thermal conductivity of glass fiber reinforced plastic section is 0.39W/m. K, only 1/100 ~ 1/1000 of metal, it is a good thermal insulation material. In addition, the glass fiber reinforced plastic section is an empty stomach structure, and all the gaps are provided with rubber strips and top sealing, so the heat insulation and heat preservation effect is remarkable. After testing, glass steel casement (single box double glass window) heat transfer coefficient K0=2.2W/ (m2, K), is the 8 level of GB in GB/T8484 - 2002 standard; glass steel casement (single frame glass window three) heat transfer coefficient K0=1.8W/ (m2, K), is the 9 level in GB/T8484 - 2002 standard GB glass; steel casement (single frame three glass, Low-E glass) heat transfer coefficient K0=1.3W/ (M2 - K), is the national standard GB/T8484 - 2002 standard level 10.
(three) good sealing performance
FRP doors and windows in the assembly process, angle processing using adhesive and screw technology, while all cracks are rubber strip and top seal, coupled with special profiles structure, so the sealing performance is good. The national construction engineering quality supervision and inspection center, Beijing city building hardware plumbing products quality supervision and inspection station, Beijing city construction quality testing center were detected, the air tightness reached the national standard GB/T7107 - 2002 standard in 5 levels; the watertight performance reached level 3 in GB/T7107 - 2002 standard gb.
(four) health, green environmental protection, energy-saving effect is remarkable
The test results of glass fiber reinforced plastic doors and windows are in accordance with the requirements of GB6566 - 2001, "building materials radioactive nuclide limits". The test results are 0.2, the internal radiation index is 0.2, and the external irradiation index is 0.2.
(five) sound insulation effect is good
The national construction engineering quality supervision and inspection center, "Beijing sanvoon sunshine" brand glass steel double and three glass windows sound right across the air volume reached 36 RW dB and 39dB, the sound insulation performance of grade 4.
(six) corrosion resistance
Glass fiber reinforced plastic (FRP) is an excellent corrosion resistant material. It has good resistance to acids, alkalis, salts, most organic compounds, sea water and humidity. It also acts against microorganisms. This property is particularly suitable for use in wet, wet and coastal areas as well as in corrosive media.
(seven) good dimensional stability
The coefficient of linear expansion of GRP profiles is 7.3 * 10-6/ DEG C, lower than that of steel and aluminum alloy [1], which is 1/15 of plastic. Therefore, the glass steel door and window dimensional stability is good, the temperature changes will not affect the normal switching function of doors and windows.
(eight) good weather
Glass fiber reinforced plastic is a thermosetting plastic. When the resin is cross-linked, it forms a three-dimensional reticular molecular structure, which becomes insoluble and melts. Even if it is heated, it will not melt. The thermal deformation temperature of the glass steel section bar is above 200 DEG C, and the high temperature resistance property is good. And low temperature performance better.
(nine) good insulation
Glass fiber reinforced plastic is a good insulating material, it is not affected by electromagnetic waves, and does not reflect radio waves. It has good microwave permeability and can withstand high voltage without damage. Therefore, FRP doors and windows are of special use to buildings in the field, temporary buildings and communication systems.
(ten) good shock absorption performance
The elastic modulus of glass steel is 20900, shock frequency it is made with windows and doors with high, combined with the resin and fiber interface of glass steel, with shock absorption and shock resistant ability, avoid the structure in the working condition of resonance caused by early damage.
(eleven) rich in color
Glass steel profile hardness is high, can be painted all kinds of coatings, made of various colors of doors and windows, in order to adapt to different styles and grades of building Wailimian effect.
