Common classification of building glass
Common classification,according to insulated glazing units insulated glass factory Hiking Glass.
One. Float hollow glasstwo. Tempered insulating glass
three. Coated insulating glass
four. LOW-E insulating glass Common insulating glass: 5+9A+5 double-layer hollow.
insulated glazing units insulated glass factory Hiking Glass doors and windows explained that 5 means that the thickness of the glass is 5mm, 9 means that the hollow part is 9mm, and the letter A is the abbreviation of air. There are models 5+15A+5, 5+22A+5, 5+27A+5, 5+32A+5, etc. on the market. It is not difficult to understand the meaning of the above. Safety performance Due to the good heat insulation performance of insulating glass, the temperature difference between the two sides of the glass is large, and the effect of cold radiation can be reduced; when the outdoor temperature is -10℃, the temperature in front of the indoor single-layer glass window is -2℃ and the hollow The temperature in front of the glass window is 13°C; in the same house structure, when the outdoor temperature is -8°C and the indoor temperature is 20°C, the cold radiation area of 3mm ordinary single-layer glass accounts for 67.4% of the indoor space, and double-layer Insulating glass (3+6+3) is 13.4%.
The use of insulated glazing units can improve the safety performance of the glass. In the case of using the same thickness of the original glass, the wind pressure strength of the insulating glass is 1.5 times that of ordinary single glass. Prospects The upgrading of the consumption structure of residents, the encouragement of independent innovation by enterprises, the construction of new rural areas and the process of urbanization will all ensure that the growth trend of the domestic market for glass products in the medium and long term remains unchanged. With the development of construction, automobile, decoration, furniture, information industry technology and other industries and the improvement of people's requirements for living space environment, functionally processed products such as safety glass and energy-saving insulating glass are widespread. The supply and demand patterns as well as the consumption structure of flat glass are changing.The development of the glass industry is related to many industries in the national economy, and the glass industry plays a positive role in promoting the development of the entire national economy.
The "Eleventh Five-Year Plan" therefore also places specific requirements on the development of the glass industry. Various laws and regulations have also been enacted to regulate the healthy development of the glass industry.Under the new situation, the glass industry must change the growth mode and effectively adjust the industrial structure in accordance with the requirements of the scientific development concept by insulated glazing units insulated glass factory, in order to promote the healthy development of the industry. [3] Design Points
1 Trough aluminum double-sealed insulated glazing units uses butyl rubber for the first seal, which has extremely low water vapor transmission rate; the second sealant mainly includes polysulfide glue and silicone glue. The water vapor transmission rate of polysulfide glue is lower than that of silicone glue, but its UV resistance is not as good as that of silicone glue, so it is suitable for windows or framed glass curtain walls (because the aluminum frame can shade and avoid direct sunlight); silicone glue is suitable for The hidden frame glass curtain wall has higher UV resistance and strength than polysulfide glue. When the building has higher decorative requirements for insulating glass, milky white or transparent silicone glue can be used. For wooden windows, silicone glue should not be used as the second seal because of its poor resistance to wood preservatives, and the sealant will be damaged due to migration.
2 The partition aluminum frame should adopt the continuous long tube elbow type, and the joints should be sealed with butyl rubber; if the partition aluminum frame adopts the four-corner plug-in type, the joints of the partition should also be sealed with butyl rubber. Insulating glass, the service life is not as good as the former. When the second sealant of insulated glazing units insulated glass factory adopts silicone glue, the insulating glass with four-corner plug-in spacer aluminum frame should not be used.
3 Because the sealant is used for sealing, it should not be used at a temperature of 70°C or higher, otherwise it will greatly affect the service life of the insulated glazing units insulated glass factory.
4 The change in the internal pressure of the air layer of insulated glazing units deforms the glass, which will cause image distortion. Therefore, when insulated glazing units is used at an altitude of 1000m or above, the air pressure must be adjusted, and the insulated glass factory should be discussed when placing an order.
5 The thermal insulation performance of the window is closely related to the window frame material, so a window frame material with good thermal insulation performance should be selected.
6 If used as a lighting ceiling, the indoor side glass should be laminated or explosion-proof film.
7 Low-E insulated glass factory, the membrane surface is located on the second or third surface, which should be selected according to design requirements. If the designed hollow glass must be in the form of large and small pieces, the membrane surface must be placed on the third side.
8 The maximum allowable area of the four-sided supporting insulated glazing units is 1.5 times the maximum allowable area of the insulating glass calculated by the thickness of two single glass sheets.
9 The following technical performance requirements should be put forward during building design: thermal insulation performance, thermal insulation performance, sound insulation performance, lighting performance, sealing performance, and weather resistance.
