Technical field
The invention belongs to field of titanium dioxide production, and in particular to the co-production technology of a kind of general titanium white and papermaking titanium white, from
And obtain the technology of high quality titanium white powder.
Background technology
Titanium dioxide chemical property is stable, is not reacted with most of material in general.The dioxy in nature
Changing titanium has three kinds of crystallizations：Plate titanium-type, rutile titania and rutile-type.Plate titanium-type is unstable crystal formation, no industrial utility value, rutile titania
Type (Anatase) abbreviation A types, and rutile-type (Rutile) abbreviation R types, all there is stable lattice, be important white face
Material and porcelain glaze, relatively there are superior whiteness, tinting strength, tinting power, covering power, weatherability, heat resistance with other Chinese whites and change
Stability is learned, particularly no toxicity, is a kind of current best Chinese white of performance in the world, is widely used in coating, modeling
The industry such as material, papermaking, printing-ink, chemical fibre, rubber, cosmetics.
Titanium dioxide application field of papermaking：Papermaking is the third-largest user of titanium dioxide, and facing paper, Bible paper and bank note are (such as：Word
Allusion quotation, magazine, journal surface, computer, banknote, duplicator paper and facing paper etc.) in must use titanium dioxide, use titanium dioxide
Paper, whiteness is good, intensity is high, it is glossy, thin and smooth, printing when do not penetrate, opacity compares carbonic acid under the same conditions
Calcium, talcum powder are high 10 times, and weight can also mitigate 15%~30%.Facing paper is also referred to as titanium white paper, be mainly used in make furniture,
The raw material of plate, wallpaper etc..Rutile is used for weather-proof, ash-rich paper, because cost ratio of the titanium white in papermaking is up to
30~50%, therefore paper mill can never use rutile in the case where meeting that user requires using anatase titanium dioxide.
Titanium dioxide general field：General titanium dioxide be widely used in coating, rubber, ink, paper, chemical fibre, ceramics, daily use chemicals,
The industries such as medicine, food.

(CN104119702B) higher requirement is respectively provided with from pigment performance and application performance, therefore in actual production process, it is right
The impurity in process control, crush, post processing etc. must be controlled strictly；Papermaking titanium white (CN104179066A) is for pigment performance
The requirement of (brightness, whiteness) is slightly below general titanium white, and 0.1 is often added in order to improve its light resistance mainly due to papermaking titanium white
~1.0% coloured rare earth element, therefore whiteness is unable to reach general titanium white requirement, and in paper-making process titanium dioxide addition just
It is scattered in water paste, due to the solid base that paper pulp originally granularity is larger, its main function is exactly to retain
Titanium dioxide improves the purpose of covering, titanium dioxide inherently hydroaropic substance, therefore titanium white so as to reach and divided in paper pulp
It is scattered to be natively easy to, particular/special requirement is had no for product dispersiveness, but the weatherability of papermaking titanium dioxide requires higher, this
It is individual mainly to be realized by conversion ratio and coating uniform recipe design.
Domestic typical Production By Sulfuric Acid Process titanium white is mainly made up of following several processes：Raw ore crushes；With sulfuric acid decomposition essence
Ore deposit extracting sulfuric acid oxygen titanium solution；Solution purification iron removaling；Hydrolyzed by titanium sulfate solution and separate out metatitanic acid；Metatitanic acid is washed through one, and two wash,
Salt treatment obtain metatitanic acid calcining be made titanium dioxide and according to different purposes to calcining gained titanium dioxide carry out it is various after
Processing is so as to good, the high whiteness that obtains surface nature, the high rutile titanium dioxide finished product of dispersiveness.In above-mentioned production process
One wash, two wash, press filtration, calcining spray (powder containing tail, hereafter identical), three wash before kiln will all produce substantial amounts of waste water, in waste water
The titanium dioxide that unavoidably generation of (filter plate is damaged, and filter cloth is damaged, and filter cloth is not arranged by specification) is largely lost in, in order to improve
Titanium yield, production cost is reduced, about 10-20ppm Flokal B, the dioxy to be suspended in waste water are generally added into waste water
Change titanium agglomerate grain, precipitation, reach the purpose of supernatant Sewage treatment titanium dioxide, but produce in this process substantial amounts of
Thick slurry, thick slurry are substantially that titanium dioxide and Flokal B occur charge neutrality reaction and precipitate and obtain, therefore almost all of
Flocculant is in thick slurry.Thick slurry viscosity is big, and shipwreck is with through by the washing of routine, bleaching process is unable to reach normal thing
The clean result of material, therefore produced a very large impact for product quality.
Iron related data after table 2. produces the various thick slurry amounts of ton titanium dioxide and bleached
