Research on modeling and analysis of carbon emission from tire mold remanufacture
Remanufacturing tire molds emerges as a pivotal strategy in the pursuit of"peak carbon and carbon neutrality"objectives.Based on the life cycle assessment theory,this paper systematically examines the carbon emissions throughout the tire mold remanufacturing process.A quantitative model of carbon emissions based on material flow,energy flow and waste flow is established,and the carbon emission of equipment,material and waste in each stage is obtained.Focusing on the sidewall plate as a representative component various processes such as welding repair,turning repair,milling repair and lettering are employed.The life cycle carbon emissions of the remanufacturing process are then computed.For the prospect with high carbon emissions,it is proposed to reduce carbon emissions by optimizing equipment and improving processing technology.The results indicate that the carbon emission of equipment,materials and wastes at each stage can be efficiently obtained by using the life cycle theory;the carbon emissions of materials and energy in the sidewall remanufacturing process accounted for 75.3%and 18.3%respectively;after the transformation of the process,its carbon emissions decreased by 10.7%and 6.1%respectively,signifying a substantial impact on energy conservation and carbon reduction.
