Is tungsten carbide spraying harmful to human health?

Many people say that for the sake of health, it is recommended not to enter a hard alloy factory, but is there any basis for this statement? Next, let's talk about whether the cough resistant tungsten salt coating produced by the hard alloy factory is harmful to human health. Tungsten carbide is a type of hard alloy material. The commonly used raw material for industrial production of tungsten carbide is tungsten carbide powder, which is used in many tungsten carbide technologies including tungsten carbide spraying technology. As is well known, ordinary dust is harmful to the human body, so is tungsten carbide powder also harmful to the human body?

Foreign chemical and physical research has shown that tungsten carbide powder can be stabilized by albumin or serum in nutrient solutions. If it is very close to the human body, adding albumin to nutrient solution can be studied, and electron microscopy can be used for examination. Tungsten carbide nanoparticles are absorbed by cells. Subsequent biological experiments showed that a single tungsten carbide nanoparticle had no odor.

In fact, it is precisely because tungsten carbide has no toxicity or side effects on the human body that it has been widely used in many occasions, especially in some consumer industries such as manufacturing rings.. In addition, there is another type of tungsten carbide powder that contains cobalt element, namely tungsten carbide nanoparticles, which are highly toxic to the human body. However, in order to produce harmful effects, this toxicity requires higher concentrations. Scientists still don't know why the combination of tungsten carbide and cobalt becomes more toxic.

In general, tungsten carbide powder does not cause harm to the human body when in contact with it in daily life.. Of course, in order to avoid the adverse effects of exposure to large amounts of tungsten on human health, personnel producing or processing tungsten carbide should regularly monitor and check whether the tungsten content in their bodies exceeds the standard. In the tungsten carbide spraying industry, environmental workers should take measures such as toxic surfaces, gloves, eyes, and dust-proof clothing.

Take measures to prevent dust leakage, clean the workshop in a timely manner, dispose of industrial waste, and prevent secondary pollution. Although daily exposure to tungsten carbide powder is not harmful to human health, employees in the tungsten carbide production and processing industry still need to follow the formal operating requirements for production and processing, and wear appropriate labor protection equipment such as masks and gloves.
