Trotz der Fortschritte in der Technologie stehen Hersteller von Sandpumpen vor mehreren Herausforderungen. Eine der größten Herausforderungen ist der globale Wettbewerb. Besonders in aufstrebenden Märkten steigen die Anforderungen an Preis und Qualität, was es etablierten Unternehmen schwer macht, ihre Marktanteile zu halten. Darüber hinaus müssen die Hersteller sich ständig an sich ändernde Umweltvorschriften und Marktbedürfnisse anpassen.

Market dynamics also influence the price of drilling machines. Economic factors, such as fluctuations in raw material costs, changes in labor costs, and overall market demand, can lead to price variations. When demand for construction and industrial projects rises, so too can the price of drilling machines due to increased competition for high-quality equipment. Additionally, advancements in technology can render older models obsolete, affecting their resale value.

  • The European Commission banned titanium dioxide as a food additive in the EU in 2022 after the European Food Safety Authority (EFSA) conducted an updated safety assessment of E171 and concluded the panel could not eliminate concerns about its genotoxicity. 

  • Furthermore, titanium dioxide has been shown to possess antioxidant properties

  • 2. Hazard identification The MSDS should outline any potential hazards associated with the handling and use of lithopone. This includes information on the physical and chemical properties of the product, as well as any potential health hazards or environmental risks.


  • These manufacturers cater to a diverse clientele, ranging from architectural companies to automotive and industrial coating producers
  • In addition to paints and coatings, titanium dioxide powder is also widely used in the cosmetics and personal care industry. Titanium dioxide is a common ingredient in sunscreens, as it provides excellent UV protection and helps prevent sunburn and skin damage. Suppliers who can offer titanium dioxide powder that meets stringent regulatory requirements and quality standards are crucial for manufacturers of sunscreen products.
  • The first commercial production of TiO2 began in the early 20th century, using the sulfate process. This method involved reacting ilmenite ore with sulfuric acid to produce titanium sulfate, which was then calcined to obtain titanium dioxide. However, this process had several drawbacks, including high energy consumption, generation of large amounts of waste, and release of harmful gases such as sulfur dioxide. As a result, many factories transitioned to the chloride process, which offers higher purity TiO2 and reduced environmental impact.

  • It is a white crystalline powder, which 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. The density of lithopone is 4.136~4.34/cm3 and it is 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.
