detecting items: negative oxygen ion
The detection method comprises the following steps: method for referencing JC/T1016-2006
TABLE 1 Performance test results
As can be seen from the detection data in the table above, in the comparative example 1, because the modified anion releasing agent of the invention is not used, but tourmaline is directly used, the probability of contacting with air is low, and the compatibility with polypropylene is poor, the quantity of anions of the final material is seriously reduced, and the addition of the modified anion releasing agent of the invention can be seen to improve the performance of the cup body material for releasing anions;
in comparative example 2, since the porous composite powder is not modified to improve the compatibility, the compatibility with polypropylene is reduced, and the release amount of negative ions is reduced, so that the modification step of improving the compatibility of the invention can indeed improve the release amount of the negative ions in the product;
in the comparative example 3, because the step of modifying the tourmaline to enlarge the porosity is not carried out, the contact probability with the air is reduced, and the release amount of negative ions is reduced, so that the step of modifying the porosity to enlarge the porosity of the tourmaline can be seen, and the release amount of the negative ions of the product is indeed improved; has wide application prospect.
