文章论述了挥发性组分在岩浆熔体中的溶解行为及其在岩浆熔体中溶解的限制条件,在此基础上讨论了挥发性组分对岩浆演化及岩石学成因方面的意义:溶解在岩浆中的水可明显地改变矿物从岩浆中结晶出的顺序,改变岩浆熔体的演化轨迹。
补充资料:挥发性发泡剂
分子式:
CAS号:

性质:又称挥发性发泡剂。加入其使聚合物基体形成泡孔结构的物质只发生物理变化,不发生化学变化。一般是能够溶于树脂的低沸点液体或易升华固体,当树脂受热时,它们挥发或升华产生大量气体,使塑料发泡。在此过程中,发泡剂仅是在物理形态上发生变化,化学组成不变。常用的物理发泡剂主要是脂肪烃或卤代烃如戊烷、己烷、三氯氟甲烷、三氯三氟乙烷等,沸点一般不超过100℃。此外,还有二氧化碳、氮气等气体。
