Definitions

  • Static mixer for mixing at least two flowable components.
  • the invention relates to a static mixer according to the preamble of claim 1 and a supply part thereof. Furthermore, the invention relates to a static mixer according to the preamble of claim 11.
  • Static mixers are used, for example, for mixing two-component putties.
  • the mixer usually has a mixer head which is connectable to a two-chamber cartridge containing the components of a mixer structure arranged in a tube, in which both components pass through a chamber or web construction, so that at the end of the mixer through an outlet nozzle of the mixed Glue exits.

  • the device is designed such that the supply of the binder component and the hardener component by means of control means to the mixing chamber of a mixing device is such that a small amount of hardener component is supplied to the mixing chamber by expansion of micro air bubbles as pre-injection with respect to the binder components.
  • the invention has for its object to improve a static mixer such that it is particularly suitable for mixing systems for polyester resins using cartridges, especially two-chamber cartridges.
  • the additional part of the invention which is preferably releasably attachable to the mixer head, it is possible to supply binder and hardener for static mixing in different levels of the mixer structure. This allows the hardener component to be sprayed into the vicinity or even directly into the chamber structure, while the rear exit openings of the binder component ensure that this component is retained at the beginning of the mixing. It has surprisingly been found that this measure leads to optimum mixing at the beginning of mixing.
  • the delay between the metering of the hardener mass and the binder mass is practically a pre-injection.
  • the hardener mass can in principle be applied directly to a cross-shaped formation of partitions of the mixer structure so that the hardener mass quickly reaches all four chambers, which leads to optimum mixing.
  • the binder component must fill by the invention at the start of mixing a resulting in the mixer head prechamber or a reservoir, since their outlet openings lie back, so that the binder component reaches the partitions of the mixer structure later than the hardener component.
  • the invention thus prevents in a simple manner that an uneven mixing of the two components takes place, which could ensure that the first outlet of 5 to 20 g from the mixing system does not harden.
  • outlet openings for the flowable components are arranged in different planes of the mixer head, so that they are arranged offset in the longitudinal direction, unscrewing the mixer from the cartridge does not lead to contamination or contact between hardener and binder, since the part according to the invention with through holes for the binder and eg one of these openings sufficiently spaced through hole is provided for the hardener. The exit of binder and hardener occurs in different levels.
  • binders and hardeners e.g. in the ratio 98: 2 (by weight) or 97: 3 (by volume) to mix and to achieve optimal mixing.
  • the invention is based on the recognition that the problems of non-uniform distribution and non-hardening of the adhesive arise from the volume distribution of the two components.
  • the cross section of the outlet openings determines the flow rate.
  • the cartridge dimensions determine the mixing ratio.
  • the mixer head is designed such that the binder component is retained, so that a pre-injection of the hardener component takes place.
  • a reservoir for the binder component is present in the mixer head in order to prevent the pre-injection of the hardener mask. to realize it.
  • the feed part is designed as a metering adapter, in which essentially the size ratio of the offset outlet openings and / or the arrangement of the outlet openings determine the mixing quality of the components.
  • the flow rate, especially at the outlet, results in a predosing of the hardener component.
  • a particularly preferred development of the invention is characterized in that the outlet openings offset in the longitudinal direction are arranged coaxially, wherein the feed part is designed for a cartridge outlet having coaxially executed outlet channels or outlet nozzles, wherein outlet openings of the cartridge are also arranged in different levels of the mixer head are.

  • the outlet openings for the binder component arranged around the preferably single central outlet opening are radially spaced from the hardener opening.
  • the binder component when turning or unscrewing the mixer from the cartridge, the binder component remains quasi in an orbit, which prevents unwanted mixing in the cartridge area.
  • the two nozzles of the cartridge are led directly to the openings of the feed part.
