china printing ink grade rutile titanium dioxide r-906

1. The process for preparing from solution, lithoponeof various grades and a soluble commercial byproduct preferably of sodium, which consists in preparing separate solutions of zinc sulfate and barium'sulfid, which solutions are mixed with each other and with that of a third salt adapted to enter into combination with a freed acid group from the firstnamed salts, the same being brought together in equivalent and calculated amounts to produce and precipitate lithopone of the desired percentage, and leave in solution the soluble by-product, substantially as described.

Titanium dioxide (TiO2) is by far the most suited white pigment to obtain whiteness and hiding power in coatings, inks and plastics. This is because it has an extremely high refractive index and it does not absorb visible light. TiO2 is also readily available as particles with the right size (d ≈ 280 nm) and the right shape (more or less spherical) as well as with a variety of post-treatments.

However, the pigment is expensive, especially when the volume prices of systems are used. And, there always remains a need to develop a full-proof strategy to obtain the best results in terms of cost/performance ratio, scattering efficiency, dispersion… while using it in coating formulations. Are you searching for the same?

Explore the detailed knowledge of TiO2 pigment, its scattering efficiency, optimization, selection, etc. to achieve the best possible white color strength and hiding power in your formulations.

  • In conclusion, gate valves with nipples are integral components in fluid control systems, offering a myriad of benefits ranging from ease of installation and maintenance to enhanced versatility in application. Their robust construction and operational efficiency make them a preferred choice across various industries. Understanding the functionality and advantages of these valves is essential for anyone involved in the design, operation, or maintenance of fluid handling systems. As technology advances, gate valves with nipples will undoubtedly continue to evolve, further solidifying their role in modern engineering solutions.


  • In every urban environment, we often pass by manhole drain covers without giving them much thought. Yet these seemingly simple objects play a crucial role in our everyday lives and the functioning of a city. manhole drain covers, designed to provide access to underground utility systems, help protect the public, maintain infrastructure integrity, and contribute to urban safety.


  • A Community-Centric Approach


  • When we think of urban infrastructure, manholes are often overlooked yet play a crucial role in the functioning of our cities. They are essential access points to underground utilities, including sewer systems, water lines, and telecommunications. One of the key features that aid in accessing these underground systems is the manhole step.

  • Moreover, pyramid bollards can be used to delineate vehicular lanes and guide traffic flow. By marking off specific areas, they help in directing vehicles to designated parking spaces or through controlled routes, thereby minimizing confusion and enhancing the overall efficiency of traffic management.


  • Metal gully grids are typically fabricated from materials such as cast iron or stainless steel, chosen for their strength and resistance to corrosion. The primary function of these grids is to cover drainage gullies, preventing debris, leaves, and other pollutants from clogging the drainage systems. By facilitating the efficient flow of water, metal gully grids help minimize the risk of flooding, protect roadways, and maintain the integrity of urban infrastructure.


  • - Prevention of Flooding During heavy rainfall or snowmelt, excess water can quickly accumulate on surfaces, leading to potential flooding. A 6% wide trench drain efficiently diverts this water, protecting structures and landscapes from damage.


  • The Significance of Tank Manhole Covers in Modern Infrastructure


  • Education and training play a crucial role in maximizing the effectiveness of construction dustbins. Workers should be trained to understand the importance of waste segregation and the proper disposal methods for different materials. This not only fosters a culture of safety but also instills a sense of responsibility toward the environment.


  • Urban environments are increasingly recognizing the crucial role that trees play in improving air quality, enhancing aesthetics, and contributing to biodiversity. However, as cities expand and asphalt dominates the landscape, protecting these valuable natural resources becomes imperative. One effective solution for maintaining the health of urban trees is the use of tree pit grates. This article explores the significance of tree pit grates and their benefits for urban landscapes.


  • The typical hose bib is made of durable materials such as brass, PVC, or stainless steel, ensuring resilience against outdoor conditions. The inclusion of the gate valve enhances its functionality by allowing users to shut off the water supply completely when necessary. This is particularly advantageous in contexts where you might need to repair or maintain connected hoses or irrigation systems without the inconvenience of draining the entire line.
