Abstract
The present application discloses method for making air adsorbent particles. The method includes the steps of: providing and mixing porous powder, water, adhesive, and additive agent for obtaining sizing agent; obtaining air adsorbent particles by spray shaping, drying, and screening the sizing agent. The mass ratio between the porous powder, water, adhesive and the additive agent is 1:(0.5˜8):(0.01˜0.16):(0.001˜0.15). Particles obtained by the method of the present application have higher strength.
