Analysis of results
The strength of the sustained-release glass particles obtained in examples and comparative examples was measured by a microsphere strength measurement method described in research on crushing strength test method for ceramic microspheres (wu nu et al, modern ceramic technology, stage 6 of 2015) (test condition 1 mm/min). As a result, it was found that:
compared with the slow-release glass particles in the embodiment 1, the glass particles obtained in the comparative examples 1-4 have poor strength, cannot effectively ensure the stability of the glass particles, and cannot provide a basis for long-term continuous and stable release of antibacterial substances.
The sustained-release antibacterial agents prepared in examples and comparative examples were tested for their sustained-release properties by the method described in section 6.7.1 of GB/T23348-2009. As a result, it was found that:
compared with the slow-release glass particles in the example 1, the slow-release glass particles obtained in the comparative examples 1, 3 and 4 release a great amount of antibacterial components at the early stage of testing, and the dissolution concentration of the antibacterial components is far greater than that of the antibacterial components on the slow-release antibacterial agent in the example; by the late stage of the test, the dissolution of the antibacterial component has not been detected in comparative examples 1, 3 and 4. The alkaline earth metal oxide, the regulator and the silicon dioxide in the components of the slow-release glass particles can generate direct influence on the slow-release performance of the slow-release carrier.
While the present invention has been described in detail with reference to the embodiments, it should not be construed as limited to the scope of the patent. Various modifications and changes may be made by those skilled in the art without inventive step within the scope of the appended claims.
