Problems solved by technology

For products with slightly less dispersibility, this method is prone to jumping of the magnetic rotor during the test process. In addition, the sample will sink to the bottom of the vortex with the generated eddy current, and then be broken by the magnetic rotor at the bottom of the vortex, affecting The effect of the test, causing the test to fail to complete

Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] The method provided by the invention is used for detecting the dispersibility of paper and products.

[0023] The detection method of the paper and products provided in this embodiment is based on figure 1 The shown paper and product dispersibility tester disperses the paper and products by generating a water vortex with shear force, and judges the dispersibility of the paper and products, as well as the time required for the paper and products to disperse.

[0024] Specifically, inject water into the barrel 3 of the paper and product dispersibility tester, so that the water volume in the barrel 3 reaches 2L-8L, so as ...

Abstract

The invention discloses a method for detecting dispersibility of paper and products, and belongs to the field of paper and product detection. The paper and the products include household paper (such as toilet paper, tissue paper, wet tissues and wet toilet paper) and toilet seat paper. Compared with the prior art, the method can achieve the effect that water vortex with shear force can be formed by accurately controlling the rotation speed of a rotor during a test process, compressed air is introduced into the bottom of a barrel to form bubble flow to prevent the paper and the products from sinking to the bottom with the generated water vortex during the test, and the paper and the products are dispersed by the shear force of the water vortex. The dispersibility of the paper and the products is evaluated by determining whether the paper and the products are dispersed within certain time or determining the time required for dispersion of the paper and the products. The method has strongoperability, high accuracy and reliable evaluation mode.

Description

technical field [0001] The invention relates to a method for detecting the dispersibility of paper and products, belonging to the field of detection of paper and products. The paper and products involved include: household paper (such as toilet paper, tissue paper, wet wipes, wet toilet paper) and toilet seat paper, etc. Background technique [0002] Household paper and toilet seat paper are disposable sanitary products, which are consumer goods for daily use. Disposal of poorly dispersed paper and its products into the toilet will cause blockage of the toilet and sewage system, thereby affecting the normal operation of the toilet and sewage system, as well as other adverse consequences. Considering the safety of consumers and the product characteristics of paper and products, the dispersibility of paper and products is an important performance for testing their quality. [0003] In Japan and other countries, the dispersibility index is clearly stipulated in the toilet pap...
