& Definition

Coated Glass
|
|
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.

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.

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. |
