It depends on the volume of the cube. the concentration of contaminants in the air. and the type of cleaning method e.g.. photocatalytic oxidation how much titanium dioxide is needed to purify the air in the cube. In the absence of more detailed information. I can't provide you with an accurate answer. If you provide more detailed information. I might be able to do so.
According to the International Agency for Research on Cancer IARC. titanium dioxide is classified as Class 2B. meaning it is likely to cause cancer in humans. This determination is based on studies showing that inhaling the dust has led to respiratory tract cancer in rats. It should be noted. however. that the IARC points out the limited evidence in humans and recommends further research. While not all exposure to titanium dioxide may be harmful. caution may be necessary. particularly in occupations with significant levels of dust exposure.
The price of polypropylene granules varies based on factors such as quality, region, and market dynamics. As of my last update in 2023, the average global price ranges from $1 to $1.5 per kilogram. However, this can fluctuate due to changes in crude oil prices, as polypropylene is a petroleum derivative. Additionally, supply chain disruptions and demand from various industries, like automotive and packaging, can further influence prices. For the most accurate and current prices, it’s advisable to consult with suppliers or market reports specific to your region and the grade of polypropylene required for your application. Remember, buying in bulk and establishing long-term supply agreements can sometimes secure more favorable pricing.
