Thermal Stability Regulation and Thermal Risk Assessment of Cottonseed Oil-containing On-site Mixed Emulsion Matrix
摘要
Abstract
To investigate the thermal decomposition characteristics of on-site mixed emulsion matrixes containing cottonseed oil and conduct thermal risk assessment,specimens of on-site mixed emulsion matrix with cottonseed oil at mass fractions of 1％,1.5％,2％and 2.5％,and a controlled specimen with engine oil at a mass fraction of 2.5％were prepared.Thermo-gravimetry(TG)was adopted to analyze the thermal decomposition process and calculate the kinetic parameters,and an ac-celerating rate calorimeter(ARC)was utilized to study the adiabatic decomposition behavior of five samples and evaluate their thermal risks.The results indicate that the cottonseed oil-containing emulsion matrix presents a new mass loss peak in compari-son with the engine oil-based emulsion matrix.With the increase of cottonseed oil content,its extrapolated onset decomposi-tion temperature and activation energy rise correspondingly,and the thermal stability of the on-site mixed emulsion matrix is im-proved.When the cottonseed oil content is more than 1.5％,the thermal stability is better than that of the 2.5％content of engine oil-based emulsion matrix.Both cottonseed oil-based and engine oil-based emulsion matrixes are graded as Grade 4 in runaway reaction probability rating and severity assessment.The matrix risk assessment presents an unacceptable risk,and the safety measurements need to be formulated.关键词
