Definitions

  • none of the known products is free from disadvantages; be it too high a dissolving speed, be it insufficient cohesion or inadequate adhesion to the container wall, so that the detergent is carried away in part or in total undissolved by the water, or be it a lack of cleaning ability due to uneven product delivery.
  • the object of the invention was to develop a cleaning block with better properties overall.
  • this block as a slowly soluble detergent depot in the water tank of flush toilets and a method for the production.
  • the cleaning agent blocks according to the invention are primarily characterized by a particularly uniform rinsing rate; ie, regardless of how far the cleaning blocks have already been removed, there is always approximately the same concentration of active ingredients in the rinse water. This is not least due to the fact that the blocks melt somewhat in the water with increasing service life and thereby the loss of surface area due to the mass erosion, approximately compensate. Also very noteworthy is the good adhesion of the blocks to the container walls, which means that the blocks are not carried away by the water flow even under unfavorable conditions, such as can be found in the suction toilets working with large amounts of water. Since the blocks also do not tend to disintegrate, they have an extremely long service life.
  • a long period of effectiveness is particularly desirable today because cisterns are increasingly being installed under plaster and these cisterns are difficult to open.
  • a further advantage of the formulations according to the invention is that all active ingredients are to a high degree ecologically compatible or readily biodegradable.
  • the production of the cleaning blocks according to the invention is particularly simple due to the fact that all solid raw materials are available in the form of fine powders and can therefore easily be intimately mixed in simple mixers such as barrel, Lödige or paddle mixers.
  • the liquid components can be introduced during the mixing process without the mixture clumping.
  • the result is a free-flowing, largely homogeneous premix which can be easily transferred to an extrusion system via screw conveyors, where it is pressed into dense strands. This procedure avoids energy-intensive stages such as heating and kneading.
  • the extruded strands are preferably given a square or rectangular shape, so that cleaning blocks in the form of cubes or cuboids can be produced therefrom. This shape is particularly preferred because it ensures an optimal contact surface in the water tanks and thus good adhesion.
  • the cleaning blocks preferably have weights of 50 to 150 g and have densities of about 1.2 to about 1.7 g / cm 3.
  • the cleaning blocks are used in such a way that one or, if necessary, also several cleaning blocks are thrown into the water tank of the flushing toilet.
  • the cleaning power then develops automatically by slowly dissolving the blocks in the water and transporting the dissolved active ingredients with the water into the toilet bowl.
  • the test was carried out in an automatically controlled toilet system, which released the contents of the water tank every 1 hour and refilled the tank with 9 liters of tap water of 17 ° German hardness and a temperature of approx. 15 ° C.
  • One block was placed in each case in the water tank and it was determined how many rinses were possible until the block was completely used up.
  • Table 2 shows the rounded results obtained in five parallel experiments.
