Ceramsite capable of realizing slow release of effective components and preparation method thereof
The invention discloses ceramsite capable of realizing slow release of effective components and a preparation method thereof. According to the ceramsite capable of realizing slow release of effectivecomponents, a slowly-released substance is used as an inner core, and an inorganic material coats the inner core to form a shell. The preparation method comprises the following steps: pretreating theprepared slowly-released substance, adding an auxiliary material to prepare the inner core, wrapping the inner core with the inorganic material through a disc type granulator, carrying out sintering or maintaining, and carrying out surface treatment according to use environments or slow-release requirements after sintering or maintaining is finished, thereby obtaining the ceramsite capable of realizing slow release of effective components. According to the invention, the inorganic material with the characteristic of porosity is used as a shell and then coats the inner core formed by the slowly-released substance; according to different application scenes, the effective components of the slowly-released substance in the core can seep out at a certain rate by changing the porosity, a pore diameter and a surface treatment mode, and liquid outside the core can also slowly seep into the core so as to allow the slowly-released substance in the core to be dissolved and then to enter environment; and thus, the purpose of long-term effectiveness is achieved.
本发明公开了一种有效成分缓释陶粒及其制备方法，所述有效成分缓释陶粒为利用被缓释物质为内核，在外包覆无机材料形成壳的有效成分缓释陶粒，将准备好被缓释物质经预处理后添加辅助材料制备成内核，将内核通过圆盘式造粒机包裹无机材料，然后进行烧结或养护，在烧结或养护结束后，可根据其使用环境或缓释要求，进行表面处理，制得有效成分缓释陶粒；本发明通过利用具有多孔性特点的无机材料作为壳，然后包覆被缓释物质形成的内核，可以根据不同的应用场景通过改变孔隙率、孔径和表面处理的方式内核里面的被缓释物质有效成分按照一定的速率渗出，也可以让内核外部液体缓慢渗入至内核，让内核里的被缓释物质溶解进入环境，起到长期有效的目的。
