Definitions

  • the present invention relates to a method for preparing a operational sealant or adhesive with an elongated commercial Cartridge, especially by thorough mixing.
  • Sealing compounds are used today for a wide variety of purposes. Sealing compounds are used to connect or glue parts and / or Sealing or filling voids or gaps. You will be particular used in the aerospace industry, in vehicle, equipment and mechanical engineering, in of construction technology, in the household or everywhere where it comes to sealing, gluing or fillings as well as corresponding repairs.
  • They are preferably used to seal construction elements, for gluing e.g. of sheets on existing structures such as Segments of an airplane or for corrosion protection in places where e.g. in the area of drilling Corrosion protection layers of the metallic construction elements injured or removed and can temporarily have a supporting function e.g. during the Take over transports of structures under construction, which can be done later still be equipped with permanent load-bearing connecting elements.
  • Adhesives are also used in a similar way to sealants for today used for a wide variety of purposes. You can do the same tasks as Apply sealants. The terms sealing compound and adhesive compound go flowing into each other.
  • Sealing compounds and adhesive compounds from more than one component that are used for Sealing, gluing, etc. must first be mixed together before the Harden thoroughly.
  • the mixing quality must be special If components that are difficult to mix, higher proportions of filler are taken into account or / and light fillers or less favorable viscosities of the individual mixing components are present.
  • sealing compound is also partially used in the sense of this invention used that - for reasons of language simplification - the term the basic composition and the basic composition mixed with the hardener.
  • the Mixture can comprise at least two components.
  • fourth or other components may include hardening accelerators, Hardener additive (s) and / or retarder may be included.
  • the term basic mass denotes a mixture that after mixing with the hardener and after Hardening with the hardener is usually understood as a sealing compound.
  • the term adhesive composition is used in part for the purposes of this invention also used in such a way that - for reasons of linguistic simplification - the Concept of the basic mass - which is sometimes referred to as the basic component - and the base compound mixed with the hardener - which is otherwise usually called Glue is called - as well as the adhesive after mixing with the hardener or after curing with the hardener.
  • the term basic mass denotes one of at least two components of a mixture, the is usually understood as an adhesive and is prepared for curing.
  • fourth or other components can be in the mixture
  • Hardening accelerator, hardener additive (s) and / or retarder may be included.
  • cartridges are often used which, after the components have been mixed, have a filling volume of prepared mass of, for example, approximately 130 cm 3 or, for example, approximately 500 cm 3 .

  • the simultaneous movement is however very uneven and the mixing effect even with simultaneous Movements minimal. Usually it only works by hand, only one at a time Only one type of movement can be performed well and reasonably evenly. In this way however, a time in the range of about 4 to 10 minutes is required to be done by hand to achieve such a mixing quality that that well prepared by mixing Mass as drops pressed between two glass plates when looking through or Oversight of the glass plates with the bruised drop with the naked eye Schlieren reveals more.
