Embodiment Construction
[0013] The raw materials for preparing the diatomite adsorption slow-release control functional material are as follows: 55-65 kg of 500-mesh diatomite powder; 0.5-1.5 kg of 1250-mesh tourmaline powder or nano titanium dioxide; 38-42 kg of 325-mesh attapulgite powder.
[0014] See figure 1 , the production method is as follows: First, the above-mentioned 500-mesh diatomite powder and a quarter of the 325-mesh attapulgite powder are stirred and mixed, and rolled into a spherical shape by a granulator. The granulation adopts the existing process, that is, rolling granulation Spray a mist liquid adhesive (aqueous solution containing 0.05% CMC); coat the remaining three-quarters of the attapulgite powder on the spherical surface for the first time, and at the same time coat 1250 mesh tourmaline powder or nano-titanium dioxide for the second time; then Drying is carried out by drying equipment at a drying temperature of 100° C. for 2 hours; finally, roasting is carried out by ...
