There are three different >types of slurry pump impellers; open, closed, and semi-open. Each has its own strengths and weaknesses, depending on the application. Some are better for solids handling, others are better for high efficiency.

We use CFD, CAD method for product design and process design based absorbing experience of world leading pump companies. We integrate molding, smelting, casting, heat treatment, machining and chemical analysis, and have professional engineering and technical personnel.

The slurry must be pumped from the absorber tank to the top of the spray tower where it is sprayed downwards as a fine mist to react with the upward moving flue gas. With pumping volumes typically in the range of 16,000 to 20,000 gallons of slurry per minute and heads of 65 to 110 feet, rubber lined slurry pumps are the optimal pumping solution.

Process speed doesn’t have anything to do with choosing slurry pump impeller, but it does have an effect on the life of slurry pump impeller. It is important to find the sweet spot that allows the slurry pump to run as slow as possible, but fast enough to keep solids from settling and clogging. If pumping too fast, the slurry can quickly erode the impeller due to its abrasive nature. This is why it is important to select a larger impeller if possible.

A safety review conducted by the EFSA in 2021 assessed thousands of studies published on titanium dioxide.

Just because we are applying makeup containing titanium dioxide as one of the ingredients does not equate sufficient coverage. Instead of relying on mineral makeup, try layering it over your daily sunscreen instead.

According to the feedback of the manufacturers, the new mainstream factory has risen, and the overall transaction center of the market has moved up. On the demand side, the terminal is currently considering stocking up in autumn, and the actual transaction willingness is enhanced; From the supply side, some mainstream manufacturers have increased the load, and the actual output of the industry has increased. Some plastics and papermaking related downstream feedback some of the tight models are more expensive. Recent titanium dioxide raw material price trend is strong, titanium dioxide price upward support also increased, comprehensive market factors, the current price of titanium dioxide rose again.

6. What happens next?

Lithopone was discovered in the 1870s by DuPont. It was manufactured by Krebs Pigments and Chemical Company and other companies. The material came in different seals, which varied in the content of zinc sulfide. Gold seal and Bronze seals contain 40-50% zinc sulfide, offering more hiding power and strength. Although its popularity peaked around 1920, approximately 223,352 tons were produced in 1990. It is mainly used in paints, putty, and in plastics.

Titanium dioxide has many purposes in both food and product development.

The European Food Safety Authority updated its safety assessment of the mineral in March 2020, stating that titanium dioxide can no longer be considered safe as a food additive. This was due to evidence of potentially harmful effects after consumption of the mineral, which may accumulate in the body over time.

The California plaintiff is apparently not the only one concerned about titanium dioxide. The European Union recently banned its use citing concerns about serious health consequences.

By September, demand in the construction sector had significantly increased; however, resurgent cases of virus hindered the anticipated recovery in demand. However, due to a severe fall in market fundamentals in some end-use areas, its prices had significantly faded by quarter-end. Delays in a number of commercial projects, followed by a poor recovery in the downstream automotive market, were identified as primary causes of the protracted recovery curve.

In a 2019 study published in the journal Nanotoxicology, researchers recreated the first phase of digestion in mice and fed them titanium dioxide, then examined whether accumulation occurred in the organs. Researchers wrote: “Significant accumulation of titanium was observed in the liver and intestine of E171-fed mice; in the latter a threefold increase in the number of TiO2 particles was also measured. Titanium accumulation in the liver was associated with necroinflammatory foci containing tissue monocytes/macrophages. Three days after the last dose, increased superoxide production and inflammation were observed in the stomach and intestine. Overall, [this] indicates that the risk for human health associated with dietary exposure to E171 needs to be carefully considered.”

For this reason alone, its time to ditch the Titanium Dioxide & give your skin a break from the relentless free radical damage.

That being said, most experts tell us that these potential health risks shouldn’t trouble us, because titanium dioxide has been used in the market for decades, and no adverse reactions have been reported by users. The bottom line is that when used correctly, titanium dioxide should be a safe ingredient that’s safe for all skin types, every day

Some websites maintain titanium dioxide is inferior to zinc oxide, another mineral sunscreen ingredient whose core characteristics are similar to those of titanium dioxide. The reality is that titanium dioxide is a great broad-spectrum SPF ingredient and is widely used in all manner of sun-protection products. What gets confusing for some consumers is trying to decipher research that ranks sunscreen ingredients by a UV spectrum graph. By most standards, broad-spectrum coverage for sunscreen ingredients is defined as one that surpasses 360 nanometers (abbreviated as “nm” - how the sun’s rays are measured). Titanium dioxide exceeds this range of protection, but depending on whose research you read, it either performs as well as or slightly below zinc oxide.

Titanium dioxide as used in sunscreens is commonly modified with other ingredients to ensure efficacy and stability. Examples of what are known as surface modifier ingredients used for titanium dioxide include stearic acid, isostearic acid, polyhydroxystearic acid, and dimethicone/methicone copolymer.

Barium sulfide is produced by carbothermic reduction of barium sulfate. Zinc sulfate is obtained from a variety of zinc products, often waste, by treatment with sulfuric acid.

Titanium dioxide prices climbed significantly in the European region during Q2 2021, owing to strong demand from the downstream sector. Major global suppliers indicated that they have seen a surge in its demand for primarily from Europe and Asia, despite a global supply constraint. Furthermore, a global player raised titanium dioxide costs in Europe by 200 USD /MT this quarter, effective Q3 2021.
