China top quality Ocean Blue Tinted Glass
What is it?
Colored float glass is also called tinted float glass, tinted float glass has excellent solar control properties. The transmittance of visible and infrared light is adjusted. Meanwhile, those rich and pure colors may meet the requirement by various building styles.
They also can be coated with Low-E, self-cleaning glass.
Advantages:
1) The body tinted float glass can reduce transmission of the sun's harmful rays by up to 80% thus minimizing fading to interior furnishings.
2) Tinted float glass can be bent, tempered or heat strengthened and in addition can be silk-screened or enameled.
3) The comprehensive range of soft natural colors compliments and harmonizes with modern building materials to provide an exciting and different look to new or existing buildings.
Application:
1.External use of windows, doors in offices, houses and shops etc
2.Interior glass screens, partitions, balcony etc
3.Shop display windows, showcases, display shelves etc
4.Furniture, table-tops etc
5.Deep processing etc
Blue colored glass is most easily produced simply by adding cobalt oxide to a batch composition. However, cobalt oxide reduces the light transmission of the glass and does relatively little to reduce the infrared (heat) transmission.
Alternatively, blue glass can be produced by using solely iron as the colorant. This is achieved by increasing the proportion of total iron in the ferrous state to very high levels or values, often in excess of 50%. However, the glass then becomes progressively more difficult to melt without the risk of inclusions being formed in the glass, particularly silica scum. Furthermore, sulphate is often used to refine the glass and, at very high ferrous levels, iron sulphide may be produced which makes the predominant color of the glass yellow or amber.
Accordingly, to overcome these problems, batches containing very low amounts of sulphate and techniques such as vacuum refining have been suggested. It has been reported that this latter procedure is, in itself, difficult to operate. Alternatively, special reagents, which are relatively expensive, may be used to avoid the need for special refining techniques. For example, oxides of tin may be required. Ultraviolet radiation absorption is, however, reduced in glasses having a high ferrous to ferric iron ratio. This is because ferric iron absorbs strongly in the ultraviolet portion of the spectrum.
