The softness of the diaper can be detected with the RRD-1000 hand softness meter. There is no very clear physical definition of "softness", so it is very complicated to derive a softness value, but softness is a comprehensive expression of the quality parameters of the diaper. Softness is a fundamental parameter for tissue products and textiles. Therefore, Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd. has developed an RRD-1000 hand-feel softness meter that is specially designed to detect the softness of diapers. RRD-1000 hand softness meter   The diaper is made of non-woven fabric, toilet paper, fluff pulp, polymer water-absorbent resin, PE film, rubber band and other materials, and is an important sanitary product for children to grow up. For a newborn baby, touch is a first step in knowing the world. It has a good tactile experience, which allows him to develop a more complete sense of security. The establishment of a sense of security has a direct impact on the development of behavior in the future. Your baby's skin is very sensitive, and if you have a little stimulation, it will make him feel very uncomfortable. Therefore, the softness of the diaper is very important to the baby. The following small series introduces how to use the hand-feel softness meter of Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd. to test the softness of the diaper?   I. Experimental project: The softness of a brand diaper was measured by RRD-1000 hand softness meter of Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd .;   Second, the experimental equipment: RRD-1000 hand-feel softness meter, suitable for measuring the softness of the tissue paper, toilet paper, wet wipes, tobacco sheets, sanitary products and other materials, RRD-1000 uses microcomputer control technology, touch screen display can be automatic It shows the whole experimental process curve, which is easy to operate and has high test accuracy. It is widely used in papermaking, hygiene products, cigarettes and quality inspection.   Third, the reference standard: GB/T8942 "paper softness determination" standard specifies the method of measuring the softness of paper by hand-type softness meter; RRD-1000 hand softness meter   4. Preparation of the model: According to the number of layers specified by the product standard, the sample is cut from the sample taken, cut into 100mm*100mm samples, and the longitudinal, lateral and front and back surfaces are marked respectively. The dimensional deviation should be no more than ±0.5mm. Whether it is embossed or unembossed sample, the sample should be uncovered and then overlapped for softness test.   Fifth, the experimental steps:   1. After starting the preheating according to the instrument manual, adjust the zero point of the instrument and adjust the slit width according to the product standard. At the same time, according to GB/T8942 "paper softness determination" Appendix A A 1 check the width error and parallelism, so that the two meet the instrument test slit width should be divided into 5.0mm, 6.35mm, 10.0mm, 20.0mm four Grade, width error should not exceed ± 0. 05mm, parallelism should not exceed 0.05mm.   2. Place the sample on the instrument test bench and make it as symmetrical as possible to the slit. Multi-layer samples should be stacked on top of each other. Turn the instrument peak/tracking switch to the peak position and press the test button to start the instrument's plate-like probe. After the probe is completely taken, the measured value is read from the display, and then the next sample is tested. Ten data should be tested in the vertical and horizontal directions.   Sixth, the experimental results:   The results are expressed as the arithmetic mean of the results of the vertical and horizontal tests, expressed in millinewtons, rounded to integers. For samples with too high softness, the test can be tested with a bending width of less than 100 mm. The results should be converted in a proportional relationship.   The baby's delicate skin needs a soft diaper with a soft feel. The soft diaper is even worse for children with diaper rash, so parents should choose a regular manufacturer for their healthy growth. Diaper manufacturers also need to use professional equipment to control product quality.
