IS CHROMITE SAND/FLOUR DANGEROUS?
Chromite sand is an ore composed of a mixture of iron, chromium oxide, silicate and other components,with Cr2O3 as main chemical and high strength,high temperature resistance and corrosion resistance;And chromite flour is produced from the raw material chromite sand through milling,mainly used in foundry,chemical,glass fields.
Although chromite sand/flour is a useful ore,but it also has some danger as follows:
1.Volatility:chromite sand/flour releases chrominum compounds at high temperature.
2.Toxicity:there is chrominum in chromite sand/flour,and chrominum is toxic metal.if touch long time,will be harmful to human.
3.Corrosivity:chromite sand/flour will corrode some metal and nonmetal.
Then how to use chromite sand/flour properly to avoid above dangers:
1.Protective measures:take protective golves,glasses etc to avoid touch skin and eyes.
2.Processing conditions:control the temperature and keep air circulation to avoid chromium volatilization.
3.Waste disposal:take action on protecting the environment when dealing with waste of chromite sand/flour.
In a word,chromite sand/flour is a useful material,but also a litte dangerous.As long as we take correct pretective measures,comply with relevant regulations and standards,it can be used safely.
