Abstract |
: |
The present work investigates the effect of the detergent content diluted in the washing water on the friction coefficient of bare foot sliding against marble tiles during walking. Two types of deodorizers as well as a disinfectant were used. The static friction coefficient of bare foot at wet and dry sliding conditions was measured. The tested detergent was added into water in concentration varied from 0 to 0.5 vol. %. The water was diluted by disinfectant of 2.0 vol. % concentration before the tested tiles were replenished by the dilution. Experiments were carried out using a test rig designed and manufactured for these tests. Loads were applied up to 700 N. The normal and friction forces were measured to determine the static friction coefficient under wet and dry sliding conditions.
Based on the experimental results, it was found that friction coefficient decreased with increasing the deodorizers content, where values of friction coefficient were relatively low so that the sliding conditions could be classified as unsafe walking. After drying, friction coefficient displayed relatively higher values than that observed by wet sliding. Besides, it was observed that friction coefficient decreased with increasing detergent content. The friction values were higher than that displayed by deodorizers. After drying, friction coefficient increased up to maximum then decreased with increasing detergent content. Diluting water by detergent and deodorizers showed drastic friction decrease for deodorizer (I). Significant friction increase was observed for deodorizer (II) at wet sliding condition. After drying, friction increased up to 0.7 at 200 N load. |
