Abstract
The invention discloses a preparation method of titanium dioxide for chemical fiber, which comprises the following steps of dispersion, ball milling, sand grinding, ion grading, post treatment, press filtering, spray drying, air flow crushing, magnetic suction and package. The preparation method is characterized in that in the dispersing step, titanium white kiln falling products are dispersed by deionized water with the pH value being 10 through being stirred for 0.5 to 1 hour at the rotating speed being 800 to 1200 r/min. The indexes of the prepared titanium dioxide such as the whiteness, the purity, the fineness, the iron trioxide content and the like completely reach the quality index of titanium white for the chemical fiber.
Description
Technical field
The present invention relates to the preparation method of a kind of chemical fibre with titanium oxide.
Background technology
In order to improve the transparency of synthon, obtain gorgeous color after making it to print and dye, usually need add matting agent.Titanium oxide is a kind of good matting agent, delustring and outer delustring in often being used to carry out.In the stoste of weaving, add quantitative titanium white, can not only obtain good permanent delustring and whitening effect, and not influence the intensity and the physicals of fiber, also can improve toughness of products, through the fiber product of titanium white delustring, easy dyeing, feel is good.
Titanium oxide requires that whiteness is good, strong coloring force, purity, fineness, ferric oxide content, burning decrement simultaneously.Water dispersibles etc. all have corresponding requirement.But the product that existing titanium dioxide production method is produced is difficult to reach requirement.
Summary of the invention
Technical problem to be solved by this invention is to the deficiency of prior art the preparation method of a kind of chemical fibre with titanium oxide to be provided; Indexs such as the whiteness of the titanium oxide of this method preparation, purity, fineness, ferric oxide content reach the quality index of chemical fibre with titanium white fully.
Technical problem to be solved by this invention can realize through following technical scheme:
A kind of chemical fibre is with the preparation method of titanium oxide; Comprise dispersion steps, ball milling step, sand milling step, ion classification step, post-processing step, press filtration step, spraying drying step, comminution by gas stream step, magnetic step and packaging step; It is characterized in that; Said dispersion steps is that titanium white is fallen the kiln article with the deionized water of pH=10, under 800～1200r/min rotating speed, stirs 0.5～1 hour.
Indexs such as the whiteness of the titanium oxide of the present invention's preparation, purity, fineness, ferric oxide content reach the quality index of chemical fibre with titanium white fully, and concrete quality index is following:
| Project | Index | Analytical results |
| Outward appearance | White powder | White powder |
| TiO 2Content % >;= | 98.5 | 98.65 |
| PH value | 7.0±0.5 | 7.2 |
| Iron (Fe) %<= | 0.005 | 0.0038 |
| Moisture %<= | 0.5 | 0.3 |
| Burning decrement %<= | 0.5 | 0.3 |
| Screenings %<= | 0.03 | 0.02 |
| Powder color L >;= | 96 | 96.5 |
| a≤ | 0 | -0.2 |
| b≤ | 1 | 0.8 |
| The moisture divergence >;= | 95 | 96 |
Embodiment
A kind of chemical fibre is with the preparation method of titanium oxide; Comprise dispersion steps, ball milling step, sand milling step, ion classification step, post-processing step, press filtration step, spraying drying step, comminution by gas stream step, magnetic step and packaging step; Its dispersion steps is that titanium white is fallen the kiln article with the deionized water of pH=10, under the 1000r/min rotating speed, stirs 0.5 hour.
