What is the main cause of baby red ass in diapers?Your baby's metabolism is very active, especially water metabolism. The younger the age, the more the number of urine. If the care is not timely, the small butt is often in a damp state. The red buttocks and diaper rash occur because the urine makes the baby's buttocks skin too moist, and a layer of natural acidic protective film on the baby's buttocks is destroyed, making the stratum corneum on the skin surface easily irritated. Wear, infiltration, and ultimately damage and inflammation of the skin, causing the baby to develop a diaper rash. The reason for the baby's red buttocks, in addition to changing the diaper or cleaning is not timely, the reason for the diaper, mainly because the diaper does not dry in a short time after urine absorption, that is, the absorption speed of the diaper is not fast enough. Why do many diapers perform well in the data of the conventional test methods, but the customers often have red ass feedback when they actually use them? Today we will analyze it in detail. The routine test method for the diaper market is to add 240 ml of normal saline in 3-4 times. After the addition is completed for 10 minutes, it is necessary to add 5 minutes after the addition, and then press the code to measure the reverse osmosis, but ignore the 0-5 minutes, especially 0. - The absorption speed and dryness of the diaper in 3 minutes, and this time is not only the data is more important is the surface dryness of the diaper, but also the most important reason for the baby's red ass. The performance of the diaper in the urine for 3 minutes is very important, only the absorption speed is fast, dry and fast, the baby's butt is not caused by the long-term wet state caused by the red buttocks. The following is a test of two diapers using conventional reverse osmosis and short-term dryness after dosing. The test methods and results are as follows: Test method one: Add physiological saline 60ml*4 times, measure the amount of reverse osmosis three times, and add 1.25kg weight to measure the amount of reverse osmosis after adding liquid for 10 minutes. Test Method 2: Add liquid physiological saline 60ml*3 times, and add 2-3 minutes after adding liquid light plexiglass plate to measure the surface tidal feeling of the diaper. The above data can be clearly seen that in the first method, the reverse osmosis is measured 10 minutes after the addition of the liquid, and the product one is obviously superior to the product two, especially the latter two reverse osmosis, but the second method has the short liquid absorption of the product one. The dryness of time is obviously worse than that of the product. It seems that the trend of the two sets of experimental data is completely opposite, but the reason for the deep research is not the same. The product uses high-water retention SAP, and the absorption speed is slow. When the solution is added for 10 minutes in the first method, the salt water has been completely absorbed by the SAP in the diaper, so the reverse osmosis data is low. However, within 0-3 minutes of adding the liquid, the salt water only infiltrated below the surface layer and was not completely absorbed by the SAP. At this time, the dryness was tested again, and the data in Table 2 appeared, and Table 1 In contrast, the reverse osmosis data is excellent in product two. Without setting too complicated a method, it is obvious that the surface of the two diapers can be touched by hand while adding 1-3 minutes of salt water. The second product is composed of all Nuoer SAP. It has the characteristics of fast absorption and fast drying. Its water retention is not as good as that of the product, but the practical effect is far better than the product. Therefore, the performance of the diaper can not simply refer to the above-mentioned first reverse osmosis data, but also pay attention to the short-term dryness of the diaper after liquid absorption, which requires the absorption speed of SAP in the diaper must be fast to ensure its dryness.
