1. What are the toxic gases produced during the vulcanization of rubber products? The vulcanization process of rubber is semi-closed vulcanization in the oven. Some rubber will emit a trace amount of toxic gas and can smell very heavy rubber. For example, sulfur monoxide, sulfur dioxide, sulfur trioxide, and hydrogen sulfide gas are not very toxic, but the products that are definitely harmful to the human body will cause carcinogenicity or the rubber before vulcanization will have less carcinogenic components. As well. The organic agents used in rubber vulcanization are more or less harmful to the human body. Such as dimethylbenzene, etc.
2. The vulcanization temperature of general rubber is generally from 115 to 180 degrees depending on the rubber type. The temperature of 200 degrees is high temperature vulcanization.
3. What are the hazards of sulfur dioxide? Hazard Category - Three Star Invasion Pathway Through the respiratory system, health hazards are easily absorbed by the moist mucosal surface to form sulfurous acid and sulfuric acid. It has a strong stimulating effect on the eye and respiratory mucosa. A large amount of inhalation can cause pulmonary edema, laryngeal edema, vocal cords and suffocation. Acute poisoning, mild poisoning, tearing, photophobia, cough, throat, sore throat and other serious poisoning can occur within a few hours of pulmonary edema, a very high concentration of inhalation can cause reflex glottic sputum and suffocation. Inflammation or burns to the skin or eye contact. Chronic effects Long-term low-level exposure may have systemic symptoms such as headache, dizziness, and fatigue, as well as chronic rhinitis, pharyngitis, bronchitis, olfactory and loss of taste. Environmental hazards can cause serious pollution to the atmosphere.
