Glass fiber reinforced plastic doors and Windows advantages large inventory
Glass fiber reinforced plastics (FRP fiber reinforced plastics profile glass fiber and its products is to strengthen material, and unsaturated polyester resin as base material, the pultrusion process produce profile after assembly made of doors and Windows, fiber glass doors and windows is the wood, steel, aluminum, plastic after another generation of new doors and Windows. Glass fiber reinforced plastic doors and Windows has the following excellent features:
(1) light high strength
The FRP profiles of density in 1.7, the it lighter than steel 4 ~ 5 times, and strength is very big, the tensile strength of 350 ~ 450 MPa, with the ordinary carbon steel close, bending strength 388 MPa, bending modulus 20900 MPa, they do not need steel reinforcement, room cloud 58-type FRP brand after the examination, the performance of wind 5.3 Kpa, more than the international GB/T7106-2002 standard, in which 8 level.
(2) insulation energy-saving
The FRP profiles coefficient of thermal conductivity of 0.39 W/m k., only 1/100 ~ 1/1000 of the metal, is excellent insulation materials. In addition, the FRP profiles for hollow structure, and all of the aperture are strip, tops seal, so adiabatic effect is remarkable. After the examination, the FRP casement Windows (single box double glass Windows) heat transfer coefficient K0 = 2.2 W / (m2 k.), of GB/T8484-2002 standard, in which 8 level. Glass fiber reinforced plastic casement Windows (single box three glass window) heat transfer coefficient K0 = 1.8 W / (m2 k.), of GB/T8484-2002 standard level 9; Glass fiber reinforced plastic casement Windows (single box three bo window, low radiation glass) heat transfer coefficient K0 = 1.3 W / (m2 k.), of GB/T8484-2002 standard 10 level.
(3) is the sealing performance
Fiber glass doors and Windows in the assembly process, anat processing with adhesive and bolt connection process, at the same time, the article rubber are all aperture and tops seal, together with special profile structure and, therefore, sealed performance is good. Kdsbuilding expert says Approved by the national construction quality supervision and inspection center, Beijing building hardware plumbing products quality supervision and inspection offices, Beijing construction engineering quality test center were testing, including air tightness reach national standard GB/T7107-2002 standard level 5; Watertight performance reach national standard GB/T7107-2002 standard 3 level.
(4) health, green environmental protection, energy saving effect is remarkable
FRP window after the examination results conform to GB6566-2001 “building material radionuclide set limit to” in building the main materials for the index requirements, test results 0.2, inside the illuminate index 0.2, external radiation index of 0.2.
(5) sound insulation effect is good
Approved by the national construction quality supervision and inspection center detection, room cloud brand double glass and glass fiber reinforced plastic three glass window air sound sum right every volume RW achieved respectively 36 dB and 39 dB, sound insulation performance level for the level 4.
(6) corrosion
Glass fiber reinforced plastic is excellent corrosion resistant material, the acid, alkali, salt and organic matter most, the water of the sea and damp good resistance ability, to the microbial role also have resistance performance. It has the characteristics of especially suitable for use in the rain, damp and coastal areas, and the place of corrosive medium.
(7) size stability is good
The FRP profiles of the expansion coefficient is 7.3 x 10-6 / ℃, less than steel and aluminum alloy, is 1/15 of the plastic. Therefore, fiber glass doors and Windows size stability, the change of the temperature will not affect the normal function of door window switch.
(8) weatherability
Glass fiber reinforced plastic of thermosetting plastic, resin crosslinking is formed namely after three dimensional network molecular structure, become do not dissolve don’t melt, even if heated also won’t melt. The FRP profiles the heat distortion temperature in 200 ℃ above, high temperature resistant performance is good. And low temperature resistance performance is better.
(9) insulation performance is good
Glass fiber reinforced plastic is good insulation material, it from the electromagnetic wave effect, not reflected radio waves, through microwave sex good, can endure high voltage without damage. Therefore, fiber glass doorsand Windows in the backcountry temporary buildings and communication system building with special purposes.
(10) damping performance is good
The FRP profiles the modulus of elasticity for 20900, and use it to the door window that makes has high damping frequency, glass fiber reinforced plastic resin and fiber in the combination of the interface, with shock absorption and earthquake-resistant ability, to avoid the structure in the working status of early destruction caused by resonance.
(11) is rich in color
The FRP profiles high hardness, paint coating, make all sorts of color of the doors and Windows, in order to adapt to the different styles and grades of outside the building elevation effects.
