For float glass, there are four major characteristics of float glass according to the classification of building glass, including the properties of clean glass, decorative glass, safety glass and energy-saving decorative glass.
The characteristic of clean glass
1) Good fluorescence and light transmittance (the visible light transmittance of 3mm and 5mm thick glass is 87% and 84% respectively).The transmission rate of near-infrared thermal rays from sunlight is higher, but the far-infrared long-wave thermal rays from the reflection of visible light to the floor of the indoor wall roof, furniture and fabric are effectively blocked, thus producing obvious "warming room effect".The transmission rate of net glass to ultraviolet ray in sunlight is low.
2) Sound insulation and certain insulation performance.
3) Tensile strength is far less than compressive strength and is a typical brittle material.
4) The clean glass has high chemical stability. Generally, it has strong resistance to acid-base salt and chemical kit gas. However, long-term exposure to corrosive media can also lead to deterioration and destruction.
5) Poor thermal stability and quick cold and hot cracking easily occur.
2.The characteristics of decorative glass
1) Colorful flat glass can be assembled into various types of groups, and has the features of corrosion-resistant, anti-scour and easy to clean.
2) Glazed glass has good chemical stability and decoration.
3) Pattern glass, sprayed glass, emulsion glass, etched glass and iced glass have various colors, impressions and luster effects and are full of decorative effects according to the different processes of making patterns.
3.The characteristics of safety glass
1)Tempered glass has high mechanical strength, good elasticity, good thermal stability, and is not easy to hurt after being broken, which can cause self-explosion.
2) When the wire glass is impacted or the temperature changes suddenly, the fragments will not disperse;It can prevent the flame from spreading for a short time.The wire glass has certain anti - theft, anti - robbery function.
3) Laminated glass has good transparency, high impact resistance, and the adhesive effect of sandwich PVB film can protect the fragments from falling and hurting people. It has high durability, heat resistance, humidity resistance and cold resistance.
4. The characteristics of Energy-saving decorative glass
1) Colored glass can effectively absorb solar radiation heat, thus achieving heat shielding and energy saving effect.Absorb more visible light, making the light through soft.Strong absorption of uv, to prevent the impact of uv on the indoor.The color is gorgeous and durable, and the appearance of the building is beautiful.
2) Coated glass has good thermal insulation effect and is easy to cause light pollution to the external environment.
3) Insulating glass has good optical performance, thermal insulation performance, anti-condensation and sound insulation performance.
