  • Publication number: 20230061371
    Abstract: The disclosure relates to a method for reducing volatile organic compounds (VOC) from wood chips for wood fibre production in a processing system, at least comprising the following consecutive steps: a first thermal treatment of the wood chips in a first thermal treatment device, which is designed to receive VOC-containing waste gases; cleaning the wood chips in a washing device; a second thermal treatment of the wood chips in a second thermal treatment device, which is designed to receive and separate VOC-containing waste gases; digesting the wood chips in a digester, which is designed to receive and separate VOC-containing waste gases; and crushing the wood chips in a refiner, which is designed to separate VOC-containing waste gases. This allows for an efficient, and thus energy-optimised or environmentally friendly and therefore also cost-optimised reduction of volatile organic compounds from wood chips.

  • Patent number: 10385244
    Abstract: The present invention comprises a single-component binder for heat-sealing applications which can be used for the sealing of polyester foils, in particular of polyethylene terephthalate foils (PET foils) with respect to containers made of polystyrene, of PVC, and of polyester. These polyesters can in particular be polyethylene terephthalate (PET) or polylactic acid (PLA). The binders here feature not only good seal seam strengths but also in particular good transparency and excellent application properties. A substantive aspect of the invention is that the sealing can be achieved without addition of adhesion promoters, in particular without addition of adhesion promoters based on polyvinyl chloride (PVC) or on polyester, and that barrier properties and sealing properties achieved in respect of containers made of PS and of PET are nevertheless at least comparable with, and sometimes better than, those achieved with heat-sealing systems already marketed.

  • Patent number: 10195829
    Abstract: A transparent, heat-sealable coating for transparent PET packaging foils can be provided by using a heat-sealable lacquer based on styrene-containing copolymers, on poly(meth)acrylates, on at least one polyester and optionally on a tackifier, and also the process for the sealing of a foil coated with this lacquer. It is surprising here that, despite the use of a rubber based on styrene-containing polymers that is not optically compatible with polyesters and polymethacrylate, the transparency of the heat-sealable coatings is still very high.

  • Patent number: 8987380
    Abstract: The present invention relates to an innovative method for controlling the viscosity of, for example, adhesives or coating formulations. The method for controlling viscosity allows very rapid thermoplastic curing of a formulation even at room temperature and a significant reduction in the viscosity at higher temperatures, thereby regaining the capacity for simple processing and allowing, for example, the originally bonded substrates to be separated from one another again with ease. A particular aspect in this context is that a plurality of cycles of thermoplastic curing and a significant reduction in the viscosity are possible with the present system.

  • Patent number: 8916635
    Abstract: The present invention relates to an innovative method for the reversible crosslinking of, for example, adhesives or coating materials. The reversible crosslinking method allows very rapid crosslinking even at room temperature and undoing of the crosslinks at higher temperatures, thereby regaining the capacity for thermoplastic processing and allowing the originally bonded substrates to be separated from one another again with ease. A particular aspect in this context is that a plurality of cycles of crosslinking and undoing of the crosslinks are possible with the present system.
