CHEMICAL INFO THE SMALL 1X1 OF CLEANING I E H C S N H C E T I E M E H C ABOUT THE TYPE OF POLLUTION TO THE CORRECT CLEANING SOLUTION! At the beginning, the question of the type of pollution must be clarified. There are three groups of pollution: organic, neutral and inorganic pollution. When selecting the cleaning agent for the first time, the relationship between the type of soiling and the pH value should be taken into account. The pH value is an indication of the strength of an acidic or alkaline, aqueous solution. The information is given in digits from 0 to 14, with 7 indicating a neutral solution. Inorganic contamination Urine scale, lime, cement veil, rust, brake dust, flash rust, water scale, soap residue, mortar and concrete encrustations and much more. neutral soiling fungi, lichens, odors, body fats, protein incrustations, oils, fats, protein deposits, coffee, sauce and much more. m. Organic pollution Oils, fats, smoke resin, blood, protein, insects, cooking residues, nicotine, wax and much more. ACID CLEANERS pH value <7 NEUTRAL CLEANERS pH value = 7 ALKALINE CLEANERS pH value> 7 0 5 strongly acidic mildly acidic 7 9 14 mildly alkaline strongly alkaline MIXING RATIOS The strength of a cleaning agent is determined by factors such as e.g. B. The starting active ingredient, the type of surfactants, the foam activators contained, but also the pH of the ready-to-use mixture is determined. In general, the following statement can be made: "The more the pH value deviates from the neutral range, the more cleaning-intensive and aggressive the solution is to dirt and surfaces." At this point, a compromise has to be made. The older and more stubborn the dirt, the more intensive the cleaner should be. However, this can only be chosen so intensely that the surface is not damaged. As a guideline, the mixing ratios of our cleaners are divided into basic and maintenance cleaning, and there is also information about processing in the high-pressure foam lance. BASIC CLEANING: Medium to heavy soiling MAINTENANCE CLEANING: Light soiling If you are unsure whether the surface is stable against the intensity of the cleaner, start with a less powerful cleaner and test it on a hidden area, observing the relevant safety instructions. TIPS AND TRICKS FOR SUCCESSFUL APPLICATION! 1. To ensure safe use, it is essential that you read all the safety instructions on the label and on the safety data sheet (www.iwetec.com) before use. 2. With concentrates, make sure that the selected mixing ratio is set in such a way that it removes the dirt quickly but does not damage the surface. 3. Never clean on hot surfaces or in direct sunlight, as the solvent will evaporate too quickly and residues will burn into the surface. 4. If a maximum exposure time is specified, then adhere to it. If the exposure time is exceeded, the surface can be damaged despite the correct mixing ratio. 5. On sloping or vertical surfaces, always apply the cleaning agent from bottom to top and rinse from top to bottom. If you clean in the reverse order, this leads to the formation of streaks on the not completely wetted surface, since the solvent evaporates more quickly and leaves residues behind. 6. After cleaning, you should always rinse the surface with clear water or other neutralizing solutions. In this way, the very high or low pH value of a cleaning solution can be neutralized. 7. Always test the product in advance in a concealed place. 20 B2B ONLINE SHOP - eshop. iwetec.de
