coating titanium dioxide manufacturer

White crystalline powder. It is a mixture of zinc sulfide and barium sulfate. The more zinc sulfide it contains, the stronger the hiding power and the higher the quality. Density 4.136~4.34 g/cm3, insoluble in water. It easily decomposes when exposed to acid to produce hydrogen sulfide gas, but does not work when exposed to hydrogen sulfide and alkaline solutions. It turns into light gray after being exposed to ultraviolet rays in the sun for 6 to 7 hours, but it still returns to its original color when placed in a dark place. It is easy to oxidize in the air and will agglomerate and deteriorate when exposed to moisture.

  • Rutile titanium dioxideThis week, the domestic rutile titanium dioxide mainstream negotiation interval is stable, and the overall market center of gravity is up. As of the close of this week, the average price of the weekly rutile titanium dioxide national market assessment was 16,558 yuan/ton, up 288 yuan/ton from the average price last week, an increase of 1.77%, and the increase narrowed by 0.03 percentage points from last week. Within the week, the new single negotiation interval is still referred to 16000-17200 yuan/ton interval (different brands of rutile products). This week, the new single stable price of titanium dioxide factory, most of the early orders of the factory are sufficient, the downstream holiday one week before the festival, the new orders in the market are reduced, and the trading atmosphere is light.This week, the domestic industry started load of 76.92%, more stable than the previous period. Domestic manufacturers maintain normal production rhythm, industry output is relatively stable; From the inventory point of view, the mainstream factory inventory days are still less than 10-15 days, the mainstream manufacturers are in short supply, and the factories rush to deliver pre-holiday orders. In terms of orders, large manufacturers receive orders relatively better than small and medium-sized manufacturers.This week, some downstream stocks according to their own dosage, and the pace of transactions has slowed down.

    Should a grade of lithopone be desired higher than the standard grade and another by-productas, for example, a forty-five*per= cent. grade of lithopone and barium chlorid the following process may be pi'acticed,\vhich, however, is quite analogous to the one already 10o described. Aqueous solutions of the ingredients are prepared as before, in these proportions: zinc sulfate, one hundred and sixty-one pounds; zinc chlorid, one hundred and thirty-six pounds, and barium sulfid, three hundred and thirty-eight pounds. Upon mixing these several solutions the lithopone will at once be precipitated in accordance with the following reaction:
