With the rapid development of the emerging industry of photocured 3D printing technology,PCW as a new type of solid waste,may pose new challenges to the environment.At present,PCW production is growing rapidly but the output is low,there is no targeted recycling and disposal method,mainly as a part of MSW for disposal,due to its thermosetting and difficult degradation characteristics,mainly incineration,but the incineration characteristics of PCW is still not clear.In this paper,the decomposition reaction characteristics of PCW during incineration were studied,and the kinetic parameters of PCW incineration reaction were calculated using FWO,Starink,and KAS model.According to the current situation of PCW along with MSW treatment,the activation energy changed before and after mixing were further compared.At the same time,TG-FTIR was used to verify the analytical results of the reaction process.The results showed that the calculation results of the KAS method and the Starink method were similar,and both their fitting effects were better.The incineration process of PCW was mainly divided into 4 stages,the activation energy was between 210～400 kJ/mol,and it was easier to decompose at high temperatures.The thermogravimetry process before and after incineration of PCW along with MSW was mainly divided into two stages.The activation energy was the highest and the reaction was the most difficult when the temperature was 440 ℃.The co-disposal of PCW and MSW would increase the energy consumption of the full combustion reaction.With the increase in PCW production,the incineration disposal of MSW may be slightly affected.With the increasing application of light curing 3D printing technology,the rational disposal of 3D printing waste should be considered.
