titanium dioxide cost suppliers

Titanium dioxide's significance in rubber production stems from its exceptional opacity and whiteness, which significantly improves the visual appeal of products like tires, rubber sheets, and various industrial rubber goods. Its ability to scatter light effectively makes it a preferred choice for creating bright, clean white shades in rubber products. Moreover, TiO2 also imparts heat resistance, enhances tensile strength, and improves the overall mechanical properties of the rubber, making it more durable and long-lasting.

I will now describe some typical methods of practicing my invention, whereby lithopone of any desired grade may be produced. One of the known grades of lithopone as prepared and mixed for the trade contains sev- 6o enteen per cent. of zinc sullid. To produce this grade and a by-product of hydrosulfid of sodium, for example, I proceed as follows: The usual precautions, it will be understood, mustbe taken in preparing or for insuring the purity of the several ingredients used; but these preliminaries do not require description here. Separate aqueous solutions of the following ingredients in the proportions named are prepared: zinc sulfate, one x hundred and sixty-one pounds; barium sulfid, three hundred and thirty-eight pounds, and sodium bisulfate one hundred and twenty pounds. These ingredients, it will be recognized, are readily soluble in water. The separate solutions are then mixed and the following chemical reaction at once takes place:

  •  1) Leaching: Ammonia-ammonium sulfate solution for leaching with an aqueous ammonia concentration of 5. 5~7. Omol/L, ammonium sulfate molar concentration of 0~lmol/L (adjusted sulfate concentration according to product type) , at a temperature of 20~50 ° C, leaching for 3h~9h, the final infusion solution is used in the next step;
