摘要:
考察了不同改进剂对十六烷相变温度、相变体积收缩率、熔解时间的影响. 结果表明,正辛烷、正壬烷、正庚烷、对二甲苯均可以调节十六烷的相变温度. 但是,正壬烷、正庚烷、对二甲苯会导致十六烷的相变体积收缩率大幅度下降,而正辛烷则较小. 当正辛烷加入质量分数为5%时,十六烷的相变温度为13.3 ℃,相变体积收缩率为9.6%. 此外,随着正辛烷质量分数的增加,不同温度条件下相变材料的熔化时间可降低15%~59%. 正辛烷是一种既能调节十六烷相变温度又可缩短其熔解时间,同时对十六烷相变体积收缩率影响较小的改进剂.
Abstract:
Effects of different modifiers on phase change temperature, volumetric contraction rate and melting time of n-hexadecane were investigated. The results show that the four modifiers of n-octane, n-nonane, n-heptane and para-xylene can adjust the phase change temperature of n-hexadecane. The volumetric contraction rate of n-hexadecane decreases sharply by n-nonane, n-heptane and para-xylene, while it varied a little by n-octane. The phase change temperature of n-hexadecane reaches 13.3 ℃ and the volumetric contraction rate of the n-hexadecane is 9.6% with 5% of n-octane. The melting times of n-hexadecane reduce 15%-59% at different temperature conditions with the increase of n-octane mass fraction. It can be concluded that n-octane is an effective modifier adjusting the phase change temperature and reducing the melting time of n-hexadecane, and has slight effect on the volumetric contraction rate of n-hexadecane.
