通过淤泥与固化剂之间发生一系列的物理化学反应。一方面添加固化剂后污泥胶体性质即刻被破坏，毛细管通道迅速建立，增加和扩散，使污泥内部水份向外扩散挥发通道打开，利于污泥的迅速干化。
Through a series of physical and chemical reactions between sludge and curing agent. On the one hand, after the addition of curing agent, the colloidal properties of sludge are destroyed immediately, and the capillary channel is rapidly established, increased and diffused, so that the water in the sludge diffuses outward and the volatilization channel is opened, which is conducive to the rapid drying of sludge.
同时固化剂和污泥中的游离态水分和破胶释放的水分进行水解和水化反应，产生大量胶凝物质和链状结晶物质，是污泥整体形成一个密实又略有空隙的整体微观蜂窝状的结构，改变了泥土性质，使淤泥具备一定的结构强度、防水，快速干化等特性。
At the same time, the curing agent hydrolyzes and hydrates the free water in the sludge and the water released by gel breaking to produce a large number of cementitious substances and chain crystalline substances. It is the overall micro honeycomb structure of the sludge with dense and slight gap, which changes the properties of the soil and makes the sludge have certain structural strength, waterproof, rapid drying and other characteristics.
