  • DE-A-23 13 330 describes soap-based lubricants which contain aqueous mixtures of Ciß-Ciß fatty acid salts and surface-active substances.
  • DE-A-36 31 953 describes a method for lubricating chain-shaped bottle conveyor belts in beverage removal plants, particularly in breweries, and for cleaning the belts using a liquid cleaning agent, which is characterized in that the chain-shaped bottle conveyor belts are based on belt lubricants neutralized primary fatty acids, which preferably have 12 to 18 carbon atoms and contain an unsaturated portion of more than 10%, lubricate and bottle conveyor belts with cationic detergents, namely quaternary ammonium compounds such as alkyltrimethyla monium, dialkyldimethylammonium and alkyldimethylbenzylammonium chlorides or organic acids.
  • the main disadvantages of these fatty amines are: the reaction with anions in water, in particular with sulfates, bicarbonates, phosphates and carbonates from alkaline waters and other water constituents; a strong reaction with carbonic acid dissolved in water to give poorly soluble ammonium carbonates, for example in the case of carbonated drinks; solubilizers must be used; cleaning the spray and Verte lSystems is necessary at regular intervals; otherwise the entire system becomes blocked and becomes unusable.
  • EP-A-0 044 458 describes lubricant preparations which are practically free of fatty acid soaps and which also contain a carboxylated nonionic surfactant and an acyl sarcosinate.

  • high substantivity and thus high lubrication performance even under unfavorable operating conditions eg belt lubrication
  • low toxicity generally usable even with equipment deficiencies
  • good cleaning effect high capillary activity and film formation on surfaces; effective even in the presence of organic loads and acids or alkalis and also non-corrosive as a concentrate; insensitive to a drink entry.

  • auxiliaries within the meaning of the present invention are also anionic or nonionic surfactants, for example alkoxylated fatty amines, fatty alcohols, alkoxylated fatty alcohols, but also alkylbenzenesulfonates soluble in hydrophilic solvents. These surfactants can improve the wetting of the chains and plate conveyor belts, should this be necessary in individual cases. In general, surfactant additives in the range from 1 to 10% by weight, based on the total formulation, are sufficient for this.

  • Spraying the bottle conveyor belt with 0.4% by weight belt lubricant solution as mentioned in the examples. Spraying performance of the nozzles: 4 1 / h, 1 nozzle per belt.
  • the coefficient of friction " ⁇ " given below is the quotient of the measured tensile stress for a bottle to the weight of the bottle in grams. Furthermore, the products were tested with hard water (16 ° d) according to the provisions of DIN 53902.
  • the foam behavior is assessed according to the following classes:
  • the coefficient of friction should be less than 0.15 for sufficient lubrication. If the value exceeds 0.15, the lubricating effect and thus the perfect transport decrease significantly.
  • the clear water solubility of the application solutions should also be guaranteed over a longer test period in order to avoid deposits in ball valve filters, nozzles, spray and distribution systems, belts and transport goods.
  • a 0.4% by weight solution was stored in 16 ° d water for 72 h and then assessed visually.
  • the foam development should be low, since excessive foam not only interferes with the workflow (automatic bottle inspector) and occupational safety (risk of slipping), but also can soften the label and penetrate into the not yet sealed container. In addition, the coefficient of friction deteriorates due to excessive foaming tendency.
  • a low level of foaming is advantageous because it requires a better distribution of the lubricant on the conveyor belts.
