• Glass processing-Special glass tempering

    Glass factories will encounter many irregular tempered glass orders,for these special orders,tempering operator should pay attention to below points and ensure good tempering quality. 1.Glass with holes and notches The holes position,diameter and notches should follow below requirement,or the glass will be easy to break during tempering process. a.Distance between hole edge to glass edge should be at least 1.5 times that of glass thickness_3-6mm. Distance between hole edge to glass edge should be at least 2 times that of…

  • Glass Processing technology -Glass Cutting

    Glass cutting is the process of cutting the standard glass panel purchased from the float glass factory according to the order size provided by the clients. Our current machines cutting capability can reach 25mm, the maximum size of is 3300*6000. For 15mm, 19mm thick glass, the extra remained margin is required to be larger, and the chipping may occur during spliting the glass, resulting in uneven glass edge. When cutting the shaped glass, the arc edge is generally hand-polished. When…

  • some misunderstanding about glass U value

    Misunderstanding 1: Thicker glass has much better U value than thin glass, laminated glass U value is significantly lower than that of the same thickness glass. For clear float glass, the increase of glass thickness does not increase the insulation performance. For example, thick 12mm clear glass and 5mm clear glass,the thickness and glass weight increased by 1.12 times. but its U value only decreased by 7.59%. The hydrogen-filled insulating glass made of 12mm glass and 5mm glass,U value decreased…

  • Laminated glass lifetime

    Laminated glass is a composite glass product in which two or more layers of organic polymer interlayer film are sandwiched between glass and processed to make the glass and the intermediate film adhere together for a long time. The laminated glass will be stuck to the film even if the glass is broken, which effectively prevents the occurrence of debris pitting and penetrating fall events, and ensures personal safety. The lifetime of laminated glass depends mainly on the material of…

  • The reasons for argon leakage for Insulated glass

    The argon filled insulated glass can improve the thermal insulation performance and sound insulation performance of the insulated glass, reduce the dew point of the insulated glass, prevent oxidation of the coated glass, and reduce the amount of failure of the insulated glass due to the stress . Maintaining argon gas that has been filled into the interior of the double glazed units glass for a long time is very beneficial for maintaining good performance of the insulated glass and…

  • The advantage of glass greenhouse

    Glass greenhouses are expensive compared with other greenhouses and are suitable for large-scale ecotourism parks. The glass greenhouse has beautiful appearance, smooth visual flow, strong wind load capacity and large displacement, and is suitable for areas with high wind and rainfall. Here are the advantages and uses of the glass greenhouse: Advantages of the glass greenhouse: 1. Evenly distributed light in the room: the triangular roof of the large slope (that is, there is only one triangular roof in one…

  • Vacuum glass VS insulated glass

    Vacuum glass is becoming the new trend of energy efficient glass,with the development of new technology,vacuum glass costs is decrease these years and becoming more and more popular. Energy conservation and environment protection ◆Super light—reduce building load-bearing and decrease building cost. ◆Super thin—Insulated glass Min configuration is 3-6-3,total 12mm,for some passive buildings,triple glazing is required with thickness between 42-50mm,that’s really thick and high costs. Vacuum glass Min thickness is only 6mm,reduce the use of frame materials,especially aluminium profiles/PVC profiles and…

  • Decent PVB new products-Achieve low iron effect through special PVB

    In the Chinaglass show during 22-25th,May,Decent PVB showed their newest PVB products named GLE PVB. The traditional way to achieve ultra clear laminated glass is through ultra clear glass and ultra clear PVB interlayer,the ultra clear glass,or low iron glass costs is about 1.5 times that of clear one,some international brands,such as PPG Starphire,price is 3-4 times that of normal clear glass.Ultra clear PVB from Trosifol is also 2 times that of normal PVB,which caused the ultra clear laminated glass…

  • 3M Dichroic glass film-Chill ,Blaze

    Chill and Blaze are the dichroic film invented by 3M company. The products appears to change color when viewed at various angles,in which Chill will appear blue/magenta/yellow and gold/blue colors,Blaze will cyan/blue/magenta and red/gold color. See below pictures to see the difference: There’re 2 different applications of these film: 1.Film with glue,specification 1220mm*30M/Rolls. It can be stick on glass surface,usually inside surface of the glass after installation,but it’s price is quite expensive,usually over USD120/SQM. 2.Film without glue,specification 1830mm*100M/roll. It can…

  • Some knowledge about ultra clear glass&heat soaked glass

    1. Why is the self-explosion rate of ultra clear tempered glass low? Low iron glass, because it contains much less iron elements than normal glass, it looks crystal clear, so it is also called ultra-white glass. Compared with float glass, in order to remove iron from the ultra-white glass in the production process, a magnetic selection process is added, and nickel is also removed during the process of removing iron, so that the content of nickel sulfide in the ultra-white…
