How to design the glass strength of insulating glass equipment

[China Glass Network] The factors affecting the quality of insulating glass are mainly the selection of raw materials and the manufacturing process. The quality of the raw materials will directly affect the quality and service life of the insulating glass. At present, there are three main types of insulating glass in China: slot aluminum single-channel sealing, slot aluminum double-channel sealing, and composite sealing strip-type insulating glass. The slot aluminum single-channel seal has been gradually eliminated due to its poor sealing performance and easy entry into moisture, resulting in condensation and frosting of the glass and short service life.

After the glass material is given, such as ordinary flat glass or tempered glass, the breaking strength of the original glass sheet is determined according to the glass strength design theory. Since the glass produced by the insulating glass machine is composed of two pieces (or two or more pieces of glass), the peripheral seal forms a sealed air layer, and when the insulating glass is subjected to a load on one side of the glass, the surface of the force-receiving glass is deformed to compress the hollow layer gas and gas. The pressure is increased and part of the load is transmitted to the other side of the glass. Therefore, in the gas-tight state, the insulating glass is the load of the two sheets of glass, and the two sheets of glass are simultaneously deformed.

Insulating glass is a two-layer or multi-layer flat glass made of a butyl wave and a polysulfide glue bonded to an aluminum frame filled with a desiccant. The original sheet glass for producing the insulating glass may be a colorless float glass, a coated glass, a tempered glass, a laminated glass, or the like. The use of ordinary flat glass should be avoided, and the transparency and strength of ordinary flat glass can not meet the requirements. The above-mentioned original glass film must meet the requirements of the corresponding standards and can only be used after passing the inspection. Different batches of glass from different manufacturers should first check for chromatic aberration before cutting, and use different chromatic aberration glass for different projects or different building façades. The glass cutting size shall be strictly implemented according to the drawings, and the operator shall pay attention to the glass surface, and shall not have obvious defects such as scratches and bubbles. Selection of aluminum strips and gussets: The thickness of the aluminum strips should be between 0.30mm and 0.35mm, the thickness should be uniform and the venting holes should be evenly distributed. Aluminum strips must be anodized or decontaminated. Be sure to use high quality and high grade products to improve the utilization of aluminum strips. The gusset size should be chosen and the surface should be cleaned. The larger advantage of insulating glass is energy saving and environmental protection. The energy consumption of modern buildings is mainly air conditioning and lighting. The former accounts for 55% and the latter accounts for 23%. Glass is a thinner and more heat-transferable material in the exterior wall of buildings.
