For glass, glass has four characteristics according to architectural glass classification, including clean glass characteristics, decorative glass characteristics, safety glass characteristics, and energy-saving decorative glass.
First, the net glass characteristics
1. Good fluoroscopy and light transmission performance (the visible light transmittance of the 3 mm, 5 mm thick slab glass is 87% and 84%, respectively). The transmittance of near-infrared heat rays in sunlight is high, but the far-infrared long-wave heat rays generated by reflection of visible light to the interior wall and furniture and fabric are effectively blocked, so that a "warm-room effect" can be produced. . The net glass has a low transmittance to ultraviolet light in sunlight;
2, sound insulation, have a certain thermal insulation performance;
3, tensile strength is much smaller than compressive strength, is a typical brittle material;
4, has a high chemical stability, usually, it has strong resistance to acid and alkali salts and chemical kit gases, but long-term exposure to aggressive media can also lead to deterioration and destruction, such as weathering of glass. And moldy will result in appearance damage and reduced light transmission performance;
5, the thermal stability is poor, rapid cold and prone to burst.
Second, decorative glass characteristics
1, color flat glass can be assembled into various groups, and has the characteristics of corrosion resistance, erosion resistance, easy cleaning.
2. Glazed glass has good chemical stability and decoration.
3, embossed glass, sprayed glass, opaque glass, engraved glass, ice glass according to the different process of making the pattern, there are a variety of colors, look, shine effect, rich in decorative.
Third, safety glass characteristics
1. Tempered glass has high mechanical strength, good elasticity, good thermal stability, and is not easy to injure after crushing, and can cause self-explosion.
2. After the impact of the wire or the sudden change of temperature, the debris will not scatter; it can prevent the flame from spreading for a short time; it has certain anti-theft and anti-robbing effects.
3. The laminated glass has good transparency and high impact resistance, and the interlayer PVB film adheres to protect the debris from being scattered and wounded, and is durable, heat-resistant, moisture-resistant and cold-resistant.
Fourth, energy-saving decorative glass
1. The colored glass absorbs the solar radiant heat effectively, and achieves the energy-saving effect of shielding heat; absorbs more visible light, makes the transmitted light soft; strongly absorbs ultraviolet rays, prevents ultraviolet rays from affecting the indoors; the color is bright and durable, and the appearance of the building is beautiful.
2, coated glass insulation effect is better, easy to produce light pollution to the outside environment.
3. The insulating glass has good optical performance, good thermal insulation performance, anti-condensation and good sound insulation performance.
