It is dangerous and safety precautions are necessary during operation.
1. Dust, any blade production inevitably requires cutting and polishing (cutting leaf roots, smoothing, cutting flanges, cutting small parts, cutting edges after processing, sanding gel coat paint, etc.), which will produce a lot of dust. These dusts cannot be broken down after entering the respiratory tract and if they accumulate in too large quantities, they can easily cause pneumoconiosis. Therefore, everyone working in the workshop must wear a dust mask or dust mask.
2. Resin curing chemical agents, epoxy resin itself is not very harmful, but the curing agent used is amine curing agent, which is very reductive and has certain toxicity. Try not to come into contact withc the skin (it will be corrosive). The same goes for epoxy adhesives. If it is polyester resin or another unsaturated resin, the damage will be even greater.
Detailed information
The harm of “dust” on the human body:
Most dust inhaled in the respiratory tract through the human body are inhaled and exhaled. In the absence of resistance, inhaled dust particles will pass through the trachea, main bronchi and bronchioles, and then enter the respiratory bronchioles, alveolar ducts and alveoli of the gas exchange zone, and produce toxic effects when of the process of entering into the person. , affecting the gas exchange function.
In fact, once inhalable dust is inhaled into the respiratory tract, it is mainly deposited in the respiratory tract by impact, gravity deposition, dispersion (also known as nom of Brownian motion), electrostatic deposition and interception. a very small amount of dust can enter the alveolar area of human lungs.
The dust particles themselves contain soluble substances or other harmful substances adsorbed in the air. Depending on their solubility, they can dissolve in the mucus of the respiratory tract or alveoli and be absorbed by the human body, thus causing a direct reaction. poisoning.
