Definitions

  • the present invention relates to a method for producing detergent tablets, in particular for use in automatic dishwashing.
  • Powder, granule or tablet detergents for dishes in dishwashers essentially consist of sodium tripolyphosphate, alkali silicate, mostly alkali metasilicate, and optionally a low-foaming, preferably chlorine-stable, nonionic surfactant and bleaching agents, preferably those that release chlorine in aqueous solution. They are mainly used to facilitate the removal of stains from tea, coffee or fruit juices.
  • the agents are strongly alkaline due to their high content of alkali silicates and sodium tripolyphosphate. Their working solutions have a pH value of around 11 to 12. An addition of sodium hydroxide is not provided, because with the contact times customary in household dishwashers, the excessive alkalinity would then attack porcelain, frosting decorations and glasses. This attack is called corrosion. Silicate, on the other hand, synergistically supports the cleaning power of the tripolyphosphate and inhibits corrosion in certain concentrations in the total tripolyphosphate / silicate mixture.
  • the known agents are generally produced by customary production processes, such as mixing or granulating.
  • the application takes place in powder or Granules in the usual concentrations, ie in amounts of about 30 to 50 g per machine filling.
  • the respective pressure level and the resulting density of the tablets is always determined by the necessary compromise between the strength and the dissolution rate of the tablets. Other factors influencing these properties are the nature of the constituents themselves and suitable tabletting aids.
  • the present invention therefore preferably relates to a process for the production of alkaline detergent tablets suitable for use in dishwashers and known composition using pressure of more than 70 kp / cm 2 characterized in that a completely crystallized granulate with a bulk density of 800 to 1200, preferably 850 to 1100 g / l, obtained by (a) partial hydration of 10 to 60, preferably 25 to 40 parts by weight of an anhydrous sodium tripolyphosphate, the 60 up to 100% consists of one of phase II and has an average grain size of 0.05 to 0.5 mm, in a continuously operating mixer (1st mixing stage) within an average residence time of 0.2 to 5 seconds with such an amount of water , as is necessary for the formation of 30 to less than 80 mol% tripolyphosphate hexahydrate and at the same time mechanical processing of the mixture such that at least 85% by weight thereof has a grain size of more than 0.2 mm and less than 2% by weight have a grain size of less than 0.1 mm, (b) mixing the
  • further granulation aids can be added agents such as anhydrous sodium carbonate, bicarbonate, sodium hydroxide or water glass, but also water, paraffin oil, which can simultaneously serve as a foam suppressant, and / or low-foaming nonionic surfactants can be added.
  • the amount of the surfactant additive should be limited to 0.1 to 2, preferably 0.2 to 0.5% by weight, since otherwise undesired foaming can occur when the tablets are used in the dishwashers in connection with the soiling of the dishes.
  • Suitable low-foaming nonionic surfactants are the known ethoxylation products of long-chain alcohols and alkylphenols, the free hydroxyl group of the polyethylene glycol ether radical being substituted by ether or acetal groups or by polypropylene glycol ether radicals to reduce the tendency to foam.
  • the block polymers of ethylene oxide with polypropylene oxide are also suitable.
  • bleaching agents come the active oxygen-releasing compounds such as perborates, preferably in conjunction with bleach activators such as. B. tetraacetylethylenediamine (TAED) or tetraacetylglycoluril (TAGU) or peracids or their salts, e.g. B. the magnesium salt of monoperphthalic acid.
  • bleach activators such as. B. tetraacetylethylenediamine (TAED) or tetraacetylglycoluril (TAGU) or peracids or their salts, e.g. B. the magnesium salt of monoperphthalic acid.
  • TAED tetraacetylethylenediamine
  • TAGU tetraacetylglycoluril
  • peracids or their salts e.g. B. the magnesium salt of monoperphthalic acid.
  • compounds which release active chlorine such as the salts of chlorine-substituted isocyanuric acids, in particular pure
  • enzymes can be used to improve the cleaning performance, preferably commercial amylases in amounts of 0.2 to 2, preferably 0.5 to 1% by weight.
  • part of the bleach-free granules can be bleached with stable dyes or pigments such as. As phthalocyanine, stain and then mix together with the bleaching agents. Fragrances, known bactericidal and dirt-suspending agents and corrosion inhibitors can also be added.
  • the mixing of the prefabricated granules with the other detergent components takes place in known mixing devices such as a Lödige mixer.
  • the finished granule-containing mixture will be as tableting preferably sodium acetate in amounts from 1 to 5, preferably 2 to 3 wt .-% and / or Dicaicium- phosphate di h ydrat in amounts of from 0.5 to 3, preferably 0.8 to 1 , 2 wt .-%, based in each case on 100% of the total tablet granulate mixture.
  • other known agents which improve the compressibility of the agents and the disintegration of the tablets during use can also be added. These include non-surface-active alkali salts of one to three-base organic carboxylic acids, e.g. As citrates, formates, benzoates, tartrates, oxalates and the like.
  • the granulate mixture prepared in this way can be pressed into any desired shape without problems.
  • Prismatic compacts with a hexagonal cross section are preferred. Their volume is determined by the desired tablet weight of approximately 20 g.
  • All known eccentric and rotary presses which can be used for the production of tablets with diameters of approximately 1.0 cm and more, are suitable for pressing the granulate mixture.
  • the compression pressure must be optimized for a given composition so that the tablets obtained are stable enough for a given weight on the one hand so that they are not damaged during packaging and transport, but on the other hand disintegrate quickly enough during use. This optimum is usually determined by the person skilled in the art by routine trial and error.
  • the density of the tablets is then - for a given mixture - a consequence of the pressure applied.
  • the compression of the tablet ingredients according to the invention has a pressing pressure of 800 to 1500, preferably 950 to 1 0 5 0 kgf / cm 2 proved to be optimal.
  • the tablets obtained by this process have an average density of 1.6 g / cm 3 and, in addition to high mechanical stability, have a uniform porous structure with a large inner surface. They therefore disintegrate particularly quickly when used in the dishwasher and can be washed into the machine faster than the granular detergent used for tabletting.
  • the tablets according to the invention can also contain other inorganic phosphate substitutes.
  • the preferred Inorganic phosphate substitutes include the synthetically produced zeolites of the NaA or NaX type, as are described, for example, in US Pat. Nos. 2,882,243 and 2,882,244. They are used in amounts of 3 to 30, preferably 5 to 10,% by weight and are added in the second mixing stage.
  • the zeolites have an additional corrosion-inhibiting effect with regard to decorative glazes on porcelain or ceramic, which goes beyond that of the known tripolyphosphate / metasilicate mixtures.
  • the tablets according to the invention also have excellent chlorine stability, although the water content of the tablets is approximately 10% by weight.
