• Vacuum Insulating Glass – Past, Present and Prognosis

    Copyright:Richard Collins; University of Sydney, First presented at GPD 2017 General description of Vacuum Insulating Glass Vacuum Insulating Glass (VIG), illustrated in Figure 1, is simply conventional insulating glazing (IG) with an evacuated space between the two glass sheets [1, 2, 3]. (Note: Due to space limitations, most of the references in this paper are to review papers, which contain source references.) VIG achieves high levels of thermal insulation using the same principles as the Dewar flask – the vacuum…

  • Advantage of vacuum glass

    Vacuum glass as a new generation of energy-efficient glass, vacuum glass has heat transfer performance advantages,the glass takes advantage of the low thermal conductivity of air. In terms of heat transfer,the thermal conductivity of the air or filled argon has small thermal conductivity. Insulated glass dominates gas heat transfer, so that the effect of improving LOW-E glass performance to reduce radiant heat is not obvious. Insulated glass made of the best LOW-E glass (such as emissivity ≤ 0.1) is filled…

  • What’s hot bending glass?

    Some projects require curved tempered glass with small radius (R< 1000mm),but most glass manufacturers cannot process this curved glass for machine limit. Let’s take LandGlass tempering machine as example,the min curved glass radius is: 5-6mm:Rmin =1000mm 8-12mm:Rmin =1500mm 15-19mm:Rmin =2500mm Then hot bending glass can solve this problem perfectly.Different from tempered glass,hot bending glass can be made in many shapes:Small radius,90 degree,double curved glass etc,here are some pics that shows the hot bending glass fantastic different shapes: C shape glass…

  • Glass Classification

    Tempered glass. It is processed by ordinary clear float glass. Tempered glass has two major characteristics compared to clear float glass: 1) The strength is several times that of clear float glass, the tensile strength is three times that of the latter, and the impact resistance is more than five times that of the float glass. 2) Tempered glass is not easy to be broken, even if it is broken, it will be broken in the form of particles without sharp angles,…

  • The history of glass

    The glass is originally obtained by solidification of acidic rocks ejected from volcanoes. Around 3,700 BC, the ancient Egyptians had made glass ornaments and simple glassware. At that time, only colored glass was produced. About 1000 BC, China made colorless glass. In the 12th century AD, commercial glass appeared and began to become an industrial material. In the 18th century, optical glass was produced to meet the needs of developing telescopes. In 1873, Belgium first produced flat glass. In 1906,…

  • The advantage of diffused glass in Greenhouse

    Glass has been used as primary glazing materials for greenhouse for long times because of its high light transmittance and longevity.Compared with other glazing materials, glass has high price and has poor thermal insulation properties.Although glass high daylight transmits , most of that light penetrates through the glazing directly;only little are diffused light. Therefore, glass-glazed greenhouse has better lighting than most other glazing choices, on sunny days the uniformity of that light is poor since the structure and overhead obstructions (heat pipes, hanging baskets, etc.) solid distinct shadows on crops below. Diffused glass is usually low iron patterned glass that scattering the sunshine. A challenge is to prevent dust from accumulating without scratching…

  • How to confirm the best PVB thickness for your project?

    Laminated glass is widely used in buildings,but confirming the best PVB thickness for your project to save the most costs and guarantee the glass quality is quite important. PVB thickness are usually 0.38mm,0.76mm,1.14mm,1.52mm,2.28mm.Here is a guideline -PVB interlayer thickness for different laminated glass-Annealed laminated glass,tempered laminated glass,heat strengthened laminated glass,curved laminated glass. Bulletproof glass,aquarium glass,and multi layer laminated glass are excluded. 1.Annealed laminated glass Glass Types Glass thickness PVB thickness L≤800mm L>800mm Annealed laminated glass ≤6mm 0.38 0.38 8mm 0.38…

  • Thermal insulation function of low e coating

    In the mid-1970s, it was discovered that most of the heat transfer of double glazing was caused by infrared radiation exchange from one layer of glass to another. Therefore, as long as the emissivity of any one of the double glazing is reduced, the heat transfer can be greatly reduced. This is the reason for LOW-E glass. There is data showing that the clear float glass has an emissivity of 0.84 and the low e coated glass with an emissivity of 0.2 reduces the…
