titanium oxide and 2 per cent' sulphuric acidand 63 per cent water, are slowly added to a solution containing 1050 pounds of barium sulphide, held in a large cylindrical tank, provided with a rotary agitation :capable of producing rapid agitation. The mass isthus v rapidly agitated, and the 2 per cent of sulphuric acid contained in the titanium acid cake reacts with a small portion of the barium sulphide. This reaction may be represented by the following equation TiO H 80 The free sulphuric acid of the titanium acid cake is neutralized by thebarium sul-' phide solution, forming barium sulphate and hydrogen sulphide, as indicated by the above equation. As the sulphuric acid is present only in a small percentage, the major porltiion of the barium sulphide remains as suc very fine colloidal suspension. The barium sulphate produced is also very fine, and the presence of this. very fine barium sulphate in suspension, and also of the very fine colloidal titanium oxide, is believed to be the explanation of the great improvement in the properties of the finished lithopone.

  • 1. Efficient Water Management The primary role of trench drain grates is to facilitate the quick and efficient drainage of water. They provide an unobstructed pathway for rainwater to enter the drainage system, helping to prevent pooling and flooding in surrounding areas. This is particularly important in regions that experience heavy rainfall, where the risk of water damage is high.


  • One of the primary advantages of stainless steel bar grating is its exceptional durability. Stainless steel is known for its toughness and ability to withstand heavy loads without deforming. This makes it an ideal choice for environments where equipment and foot traffic may exert significant pressure on the flooring. Furthermore, steel grating retains its structural integrity over time, decreasing the need for frequent replacements and repairs, thus providing a cost-effective solution for long-term projects.
