[0065] The method for preparing the material for removing formaldehyde and peculiar smell in the air in the wardrobe based on the superfine diatomite powder includes the following steps:
[0066] Step 1. Add the redispersible latex powder and water above 85°C into the device and stir evenly to obtain a glue;
[0067] Among them, the device is generally a glue tank with a heat preservation function; during the stirring process, the water is in a boiling state and evaporates. Considering the production cost, the temperature of the water is generally 85-100°C; the stirring speed is not limited, and it can be stirred evenly; The mass percentage of redispersible latex powder in the final obtained glue is 25-35%, preferably 30%; when feeding, the mass ratio of redispersible latex powder to water can be 1:10;
[0068] Step 2: Add the superfine diatomite powder into the granulator, spray the glue obtained in step 1 at 30-45°C, and granulate to obtain granules;
[0069] Among them, the granula...
