Activated clay is called the acidic argil also to call the active floridin after the acid treatment . Its principal constituent is the diatomaceous earth, itself already activated. The active floridin odourlessness is tasteless, non-toxic, activeness and adsorbability are good. In the air, easy absorption of moisture, if will lay aside too long or is affected with damp will reduce its adsorption function. When using , should heating (take 80-100 degrees as suitable). If heats up to 300 degrees above starts to lose the crystal water, the itself structure changes. The chemical constituent is SiO 2: (50~70)w%; Al 2 O 3: (10~16)w%; Fe 2 O 3: (2~4)w%; M g O: (1~6) w% and so on.. Also widely applies in professions and so on food, chemical industry, national defense and medicine health.
