Definitions

  • insulating glass is used in order to be able to store food in particular at temperatures of 5 degrees Celsius or below 5 degrees Celsius, in the so-called deep-freeze area, and at the same time present it to customers. Refrigerated shelves with glass doors are also used for this.
  • aluminum spacers have primarily been used as spacers between the two panes of glass doors installed parallel to one another, based on the same principle as insulating glazing in construction.
  • a butyl cord was applied using an extruder.
  • An aluminum profile is perforated to the inside of the pane.
  • a water-binding material e.g. B. silica gel or molecular sieve.
  • the air trapped between the two panes contains moisture, which would condense if the temperature falls below the dew point, forming precipitation on the glass panes inside the pane composite.
  • the water-binding material now binds this moisture, up to a maximum of the saturation limit of this material. If no new air comes between the two panes due to leaks in the butyl cord and the external sealing compound, e.g. B. polysulfide, the risk of condensation formation is permanently eliminated.
  • the inserted aluminum profile is surrounded on the outside by a sealing compound again with the glass tied together. Sealing compound and butyl cord thus form a double sealing system.
  • a refrigerator for storing food with an access opening located in a vertical plane, which can be closed by a pivoting or sliding and multi-glazed refrigerator door
  • the refrigerator door having at least two transparent glass panes which are spaced apart from one another by edge-side spacer elements, on a transparency -A vertical transparent spacer element made of a transparent material and no supporting frame element is provided on the vertical edge of the refrigerator door, the vertical transparent spacer element connecting the two glass panes together and keeping them at a defined distance from one another, the spacer element being designed as a hollow profile on the lower horizontal edge of the refrigerator door, wherein the hollow profile has several openings towards the space between the glass panes and the hollow spacer element is filled with desiccant which serves to absorb moisture from the space.
  • DE 11 2014 002 800 T5 discloses a glazed element for a refrigerated container furniture, with a resin-based spacer between two glass slides.
  • the EP 2 456 942 A1 discloses glass spacers which are glued between two glass plates.
  • the WO 2016/091954 A1 discloses an insulating window comprising at least two spaced glass panes for buildings, in particular for equipping exhibition halls, public and commercial building halls, verandas and pergolas and other applications apart from a cooling device with high thermal insulation and sufficient resistance to wind and others Weather influences, with polymethyl methacrylate being used as a spacer material.

  • Insulating glass panes and insulating glass elements are synonymous in this respect. For simplicity, insulating glass elements are predominantly used in the text.

This includes temperature resistance, for example in terms of shape, size, color, transparency, structure and strength. Depending on your needs, additional criteria may be added.
  • EVA is also used as an abbreviation for the name ethylene-vinyl acetate copolymer and is to be understood as having the same meaning.
  • Ethylene-vinyl acetate copolymer or Eva can be in film form or granulate form and each forms a laminating layer.
  • the connection between the glass spacers, which are preferably a soda-lime glass rod, and the two glass panes is carried out by means of a laminating layer, preferably with ethylene-vinyl acetate copolymer in film form or granulate form by lamination.
