【摘要】：Bodala,運(yùn)用靜態(tài)雙倉法建立的測(cè)定干建材中VOCs擴(kuò)散系數(shù)和分配系數(shù)的數(shù)學(xué)模型是合理的,有一定的應(yīng)用價(jià)值.但該模型假設(shè)低濃度倉中VOCs的初始濃度為零,限制了模型的應(yīng)用范圍.針對(duì)使用VOCs液體為污染源且建材透氣性較好的條件,作出合理的假設(shè),構(gòu)建了VOCs在建材中擴(kuò)散的數(shù)學(xué)模型.采用LaplaceCarson變換詳細(xì)求解模型,得出計(jì)算VOCs擴(kuò)散系數(shù)的方法,并運(yùn)用兩組數(shù)據(jù)對(duì)模型進(jìn)行了比較分析,結(jié)果表明優(yōu)化后的模型有一定的實(shí)用性和可行性.
[Abstract]:The mathematical model established by Bodala, for the determination of diffusion coefficient and distribution coefficient of VOCs in dry building materials by static double warehouse method is reasonable and has certain application value. However, the model assumes that the initial concentration of VOCs in the low concentration bin is zero, which limits the application range of the model. Aiming at the condition that VOCs liquid is used as the source of pollution and the permeability of building materials is good, a mathematical model of VOCs diffusion in building materials is constructed by making reasonable assumptions. The LaplaceCarson transform is used to solve the model in detail, and the method of calculating the diffusion coefficient of VOCs is obtained, and the two groups of data are used to compare the model. The results show that the optimized model has certain practicability and feasibility.
