Washing machines wash experiment and rate of unreliable: we want is the purpose of the use of washing equipment washing effect is better, so the washing rate is becoming the key of washing equipment quality indicators.Although the rate is very important to clean, but up to now, we still do not have the exact ideal method to appraisal.In order to meet the needs of the development of cleaning industry, experts from all over the world have done some experiments, although there is no experiment content is different, but the experimental principle and the results are the same, mainly control can affect the washing effect of external factors:
1: ensure the washing equipment of measuring point distribution and filling amount is consistent, can accurately measure the washing effect Rules of washing clothing specifications, quantity, quality of a material, the degree of pollution, pollution and clothing to the same position.
2: to use the same brand the same amount of detergent or washing powder.
3: artificial pollution of pollution sources, pollution, pollution of the use of fabric texture and pollution are consistent, can be concluded that the index is more fair and just,
4: the number of washing and at the same time.
5: the washing water temperature, water quantity and water quality are the same, after washing clothes and stored in the same way
6: to the correct use of washing equipment. According to different method of pollution and contamination, it is concluded that the results differ greatly also, if it is a pollution source is easy to wash, then wash the rate will be on the high side, on the contrary, if it is difficult to wash pollutants, washing machines wash rate is very low
But because it is artificial, the results are not necessarily fair, too.According to different method of pollution and contamination, it is concluded that the results differ greatly also, if it is a pollution source is easy to wash, then wash the rate will be on the high side, on the contrary, if it is difficult to wash pollutants, washing machines wash rate is very low.We can clearly see, pollution and pollution sources used in our study are uniform, but its actual washing and pollution vary widely, even had nothing to do, so, our experimental results only for specific pollution, are not consistent with the actual washing rate, also can not general according to the results to determine the washing machines wash rate.
