Definitions

  • copolymeric acids in which one of the components has no acid function the proportion thereof in the interest of sufficient water solubility is not more than 70 mole percent, preferably less than 60 mole percent.
  • Copolymers of acrylic acid or methacrylic acid with maleic acid have proven to be particularly suitable, as are characterized, for example, in EP 25 551-B1. These are copolymers which contain 50 to 90% by weight of acrylic acid or methacrylic acid and 50 to 10% by weight of maleic acid. Copolymers in which 60 to 85% by weight of acrylic acid and 40 to 15% by weight of maleic acid are present are particularly preferred.
  • the storage container (1) is expediently identical to the shipping container in which the product (A) is delivered. Its shape can be any. Examples of this are barrels, barrels or cartridges made of metal or plastic material or also foil packaging, for example sacks or bags, which can be packed in outer cartons. Containers with rigid outer walls and a circular or square cross section are preferred, since these facilitate the removal of the paste.
  • a controllable or automatically closing shut-off device integrated in the mixing device or in the injector avoids these possible disadvantages.
  • This shut-off device can e.g. consist of a ball shut-off valve that interrupts the access of the water to the paste feed as soon as the system is in the idle phase or a back pressure builds up inside the injector. The valve releases the feed as soon as a sufficiently large negative pressure has built up in the area of the paste feed.
  • the valve can be controlled by means of counter pressure from an adjustable spring.
  • the valve is preferably also opened and closed via the control device (9).
  • the locking device can e.g. consist of a rotatable shut-off valve, which is driven by a motor and whose position is based on the prevailing pressure conditions.
  • softened (permuted) water is used, and also for rinsing, at least for the first rinse cycle , usually softened water is used.
  • the washing process in the machine does not differ significantly from the conventional working methods, with the exception that (as explained above) the detergent can be automatically replenished if there is an increased demand as a result of heavy soiling.
