| titleOfInvention | The preparation method of nanotechnology formaldehyde scavenger |
| abstract | The preparation method of nanotechnology formaldehyde scavenger of the present invention, comprising the following steps: 1) disperse raw material titanium salt through mashing, adjusting to the concentration of slurry in terms of titanium dioxide is 150~320g/L, stirs 0.5~3h at room temperature；2) ammonium salt is added into the obtained slurries of step 1) to be precipitated, stirs 0.5~3h, adjustment pH value to 3~8 at normal temperature；3) dispersion of addition ammonium salt and secondary precipitation again, continues 2~3h of stirring；The mass ratio of ammonium salt in added ammonium salt and step 2) is 1~10；4) silver salt is added after dispersing to precipitating obtained by step 3) into its slurries and carries out intercalation, stirs 1~3h under room temperature；5) silver salt secondary intercalation is added again, continues 2~3h of stirring, blocky filter cake is obtained by filtration in the slurry wash obtained after processing；The present invention does not need the subsidiary conditions such as additional illumination, heating；Added ammonium salt is one of ammonium citrate, ammonium carbonate, ammonium sulfate or ammonium polyacrylate or a variety of, reduces the corrosion to equipment, reduces cost of investment. |
