Embodiment 1
[0028] A method for preparing soil passivation material by compounding attapulgite with phosphate wet method, the manufacturing steps are as follows:
[0029] 1) Selection of raw materials: Attapulgite and high-quality phosphate with strong adsorption, passivation and dispersibility are selected as raw materials;
[0030] 2) Crushing and grinding of raw materials: crushing and grinding the attapulgite into powder;
[0031] 3) Mixing of raw materials: stirring and mixing the crushed and ground attapulgite and high-quality phosphate until uniform;
[0032] 4) Making mud: add water to the attapulgite and high-quality phosphate after mixing, then stir to form mud, and stir the mud for 2 hours every day;
[0033] 5) drying mud: drying the mud;
[0034] 6) Pulverizing mud: pulverizing the dried mud into particles;
[0035] 7) Packing and storage: Pack the crushed particles and put them into a dry warehouse for storage.
[0036] The attapulgite and the phosphate are stirred and m...
