Terminology & Definition

 

Coated Glass

Sputtering Process
Coated glass is made by coating films on the normal glass under the vacuum condition, which changes its physical and optical characters, and possesses heat reflecting, low-emissivity and mirror distinguishing features. It is a updated product as building for saving energy material.

The products have multiplex firm coatings, high chemical stability, beautiful and uniform color. They are the crystallization of perfect combination of high quality float glass from Luoyang Glass Group with advanced technology and coating equipment from Airco Co. of America.

The products have been given the gold medal in Aisa-pacific Trade Fair (ASPAT) held in 1994 and in 1995.

The products have been tested by China National Glass Inspection Center, American G. E. Co. and Dow Corning Co. The testing results show that the adhesion capability, coating film hardness, wearability and color and etc... . It have reached and surpassed the American Airco quality standards. The products can keep the good quality at least 15 years.

Process Theory of Coating

 

The distinctive feature of solar control glass is that is transmissible for visible light and short-wave infrared ( wave length 0.30 to 2.5 micron ), while its reflectivity for far infrared ( wave length 3 to 12 micron ) radiation is up to 97 percent. That means it can reflect the great majority of heat from the sunlight therefore solar control glass can keep nice and cool and save the expenses of ventilation and air conditioning in buildings.

 

The light transmittance of solar glass goes from 8 percent to 40 percent and the shading coefficient from 0.28 to 0.56, Solar control glass can be used as monolithic or double glazing ( insulating glass ) as well.

The company supplies various kinds of solar control glass with different performance and color such as gold, silver, chrome, bronze, blue, green, and so on. A building with solar control glass as curtain wall not only shines with brilliant color but also reflects the surrounding buildings and natural scenery, hence the building will have a very nice colorful appearance.

Coated Glass Products Code and Parameter

 

 

Tempered Glass

Tempered glass is made by heating glass to just below its softening temperature and suddenly cooling it with jets of cold air. It has the following features: 3-5 times stronger than ordinary annealed glass. When breakage does occur, the glass disintegrates into small cubical fragments which greatly reduces the risk of personal injury. It withstands abrupt changes in temperature. For these reasons, tempered glass has wide applications which include doors, windows, tables, and furniture.

 

The company has imported a complete set of advanced horizontal bent tempered glass production line from Glasstech America which is world-famous tempered glass equipment manufactory. With an annul output of 500,000m2, it continuously produce tempered and semi-tempered safety glass of various styles and high quality. It'll wholeheartedly provide service to clients at home and abroad.

Insulating Glass

Insulating Glass is a kind of ideal material for modern building glazing. It has the advantage of heat insulation, constant moisture, noise-proof, anti-frest, anti-dew and energy-saving.

The insulating glass made by Jingrun has reached and surpassed the national standards after testing by China National Glass Inspection Center. The item of "Dew Point" has reached-60°C, which has surpassed the national standard (-40°C)

The company introduced the full set of insulating glass production line and glass cutting machine from Lisec G.M.B.H. Overall annual yield of insulating glass are 85000m2 with the max size 3500 * 2500mm,

The performance of glass cutting machine.
Max Size: 3700 * 2600mm
Thickness: 3 * 12mm
Cutting Speed: 80m/min
Tolerance: + 0.4mm

 

With high air-tight double sealant and second sealing process, the glass sheets are separated by aluminum frames which seal the sheets. A desiccant is placed inside the aluminum frames to sure high desiccating scale of air space between the sheets.

 

Properties of Insulating Glass

Photometry: Decided by properties of the original glass products, photometry of the insulating glass is generally within the scope of 10%-80%, reflectivity is about 13%-14%.
Heat Conduction: The thermal conductivity parameter k of double glazing is between 1.4-2.9kcal/sq.m.hr.°C, 2-4 times higher than the former.
Sound-proof: Normally, insulating glass can lower the noise level by around 30db, therefore it is sufficient to achieve a satisfactory interior noise level for most street-facing buildings.
Dew Avoidance: The dew point of insulating glass is at about-60°C, 15°C lower than ordinary single panel glass window.
Others: When achieving same heat insulation performance, using double glazing can reduce building weight, as well as improve natural lighting condition, compared with conventional brick and concrete walls. An insulating glass window could save about 40% window frame materials compared to a double-framed window.
