With the development of industry, more and more hazardous wastes are discharged in the process of industrial production, resulting in increasingly serious pollution and potential dangers. People are very sensitive to the issue of hazardous waste, so what does hazardous waste mean? Is industrial rock wool with ever-expanding demand a hazardous waste?
The full name of hazardous waste is hazardous waste, which refers to the waste that is listed in the national list of hazardous wastes or has the characteristics of hazardous wastes identified in accordance with the identification standards and identification methods of hazardous wastes stipulated by the state. Hazardous wastes have five common characteristics, namely toxicity (including leaching toxicity, acute toxicity, biological toxicity, etc.), corrosiveness, flammability, infectiousness and chemical reactivity. Solid waste with one or several hazardous properties is classified as hazardous waste.
Industrial rock wool is an industrial product, not a hazardous waste. According to the "National List of Hazardous Wastes", waste insulation materials and construction waste containing asbestos are hazardous wastes. The list does not specify that rock wool is hazardous waste. Solid wastes with unclear hazardous properties should be identified in accordance with the identification standards and identification methods of hazardous wastes stipulated by the state.
The main materials of industrial rock wool are natural rocks such as high-quality basalt and dolomite. After being melted at a high temperature above 1450°C, it is centrifuged at a high speed by an internationally advanced four-axis centrifuge to form fibers. It is made by adding water repellent, etc., after being collected by the cotton collector, by the pendulum method, and then laying cotton to solidify and cut. Uetersen rock wool does not contain asbestos, and during use, even if a fire occurs, it will not release toxic and harmful gases, and will not produce smoke and drips. As a biodegradable fiber, even if it comes into contact with the skin or is inhaled into the human body, it is easily dissolved and eliminated from the body. It has no carcinogenicity.
