- Neutral pH values are particularly preferred for clear water-soluble concentrates.
- the lubricants according to the invention are namely suitable in the concentration required for chain and belt lubrication also for cleaning empties as well as machines and machine parts.
- central foam systems in the food industry are partially equipped with permanently installed, automatic systems which, after the production process or during breaks, automatically clean the outside of fillers, cylindroconical fermentation and storage tanks, conveyor belts and other machines and systems .
- the lubricants according to the invention can be used with great advantage.
- the present invention thus also relates to the use of lubricants of the type described above for disinfecting and cleaning empties, machines and systems in the food and beverage industry.
- the PET bottles are filled with carbonated water of 4.5 vol% CO 2 and sealed accordingly.
- the bottles are immersed in the substance to be tested in the bottom area (see Table 1) and stored at 38 ° C for 72 hours. The bottle is then sampled (from no stress cracks to the destroyed bottle).
- Bottle transport speed approx. 1 m / s
- Spraying the bottle conveyor belt with 0.4% band 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 0.10 to 0.12 or less. If the value exceeds 0.15, the lubricating effect and thus the problem-free transport clearly deteriorates.
- 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.
- 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.
- Anionic surfactants such as alkylbenzenesulfonate cannot be incorporated into the cationically reacting chain lubricants based on alkylamines, so that only amine oxides and alkyl polyglucosides remain for use in corresponding chain lubricants.
- PET suitability: few cracks. Clear water solubility: opaque
- PET suitability: no cracks. Clear water solubility: slightly opaque
