  • 1.The selection of the pump is too large, and the flow and head are larger than the actual condition due to improper selection of the coefficient. This situation makes the pump in the operation process, cavitation phenomenon, resulting in premature damage of the pump flow parts under the combined action of cavitation and abrasion, in the case of serious cavitation, the pump will produce vibration and noise, and even lead to a sharp decline in the flow, head and efficiency of the pump can not run; In addition, the pump in the operation of large flow, will also cause motor overload, heat, serious will burn the motor.

  • Overall, titanium dioxide plays a critical role in the paper industry by improving the quality, performance, and appearance of a wide range of paper products. Its unique optical properties make it a valuable additive for enhancing the whiteness, brightness, and opacity of paper, while also providing important functional benefits such as print quality, show-through prevention, and light stability.
  • China is a leading producer of titanium dioxide (TiO2), especially for masterbatch and plastic use. TiO2 is a white pigment widely used in various industries such as paints, plastics, paper, and cosmetics due to its excellent opacity and UV resistance.

  • R-895:

  • With the increasing demand for titanium dioxide in various industries, manufacturers like RC 823 play a vital role in meeting this demand and driving the growth of the industry. As the market for titanium dioxide continues to expand, companies like RC 823 will continue to innovate and adapt to new trends and technologies, ensuring their position as leaders in the industry.

  • In a 2017 study published in Scientific Reports, researchers exposed rats to human-relevant levels of E171 to examine the effects of intestinal inflammation and carcinogenesis. They saw that “a 100-day E171 treatment promoted colon microinflammation and initiated preneoplastic lesions while also fostering the growth of aberrant crypt foci in a chemically induced carcinogenesis model.” They continued: “Stimulation of immune cells isolated from Peyer’s Patches [which are clusters of lymphoid follicles found in the intestine] showed a decrease in Thelper (Th)-1 IFN-γ secretion, while splenic Th1/Th17 inflammatory responses sharply increased,” researchers wrote. “A 100-day titanium dioxide treatment promoted colon microinflammation and initiated preneoplastic lesions.” The scientists concluded: “These data should be considered for risk assessments of the susceptibility to Th17-driven autoimmune diseases and to colorectal cancer in humans exposed to TiO2 from dietary sources.”

  • It’s true that titanium dioxide does not rank as high for UVA protection as zinc oxide, it ends up being a small difference (think about it like being 10 years old versus 10 years and 3 months old). This is not easily understood in terms of other factors affecting how sunscreen actives perform (such as the base formula), so many, including some dermatologists, assume that zinc oxide is superior to titanium dioxide for UVA protection. When carefully formulated, titanium dioxide provides excellent UVA protection. Its UVA protection peak is lower than that of zinc oxide, but both continue to provide protection throughout the UVA range for the same amount of time.

  • Gravimetric analysis is a method of quantitative chemical analysis in which a substance is converted into a stable compound of known composition, and the mass of this compound is then measured. This technique offers a high level of precision and is particularly useful in determining the concentration of materials within complex mixtures. The gravimetric determination of titanium dioxide typically involves a series of well-defined steps, which include precipitation, filtration, washing, drying, and weighing.


  • One common method to determine sulfate as TiO2 involves gravimetric analysis. In this technique, a sample containing sulfate is treated with barium chloride, resulting in the precipitation of barium sulfate. The precipitate is then filtered, dried, and weighed. The weight of the barium sulfate precipitate correlates directly with the amount of sulfate originally present in the sample. To express this as TiO2, a conversion factor based on stoichiometry is applied. This method, while straightforward, can be time-consuming and subject to errors in filtration and drying.
