WSJ-NH03   Adhesive strength tester for sanitary napkin


The adhesive strength tester wsj-nh03 is Jinan Chenchi According to GB / t8939 standard. However, GB / t8939 has changed the adhesive strength index of sanitary napkin from qualitative assessment to quantitative assessment, which requires that the adhesive strength of sanitary napkin should not be less than 8 seconds. Although the reference data is not used to judge whether it is qualified or not, it should at least provide a reference data for manufacturers, quality inspection institutions and colleges and universities, It also provides a basis for sanitary napkin manufacturers to provide a reasonable adhesive strength of the quality.

Test principle: 180 ° stripping method is used to apply a certain pressure to peel off the joint between the back glue of sanitary napkin or cushion sample and pure cotton sweat cloth. The bonding strength is reflected by timing the time required for stripping a certain length.

It takes a long time to reflect that the adhesive strength of sanitary napkin back is relatively high, and the adhesive of sanitary napkin is closely connected with sweat cloth. The user is not easy to fall off when walking, running and turning over in the process of use. The adhesive performance is good, and it is not easy to fall off and contaminate underwear. However, if the adhesive strength of sanitary napkin back is too high, it is easy to tear the PE breathable film when it is torn off from the underwear. The film and the adhesive stick together on the underwear, which is difficult to clean, which will also bring trouble to users.

If the stripping time is relatively short, and the adhesive strength of the napkin back is too small, it will easily fall off when the user is walking around and get contaminated with underwear, which is very embarrassing. It is estimated that users will no longer use this brand of products.


The adhesive strength device is relatively free and simple. It is produced and supplied by Jinan Chenchi Instrument Co., Ltd. the instrument is designed with three working positions. However, it must strictly comply with the test specified in the standard and be equipped with all accessories, as shown in the figure below.
