,具体为一种塑料粒子微波烘干箱。
技术介绍
塑料是以单体为原料,通过加聚或缩聚反应聚合而成的高分子化合物(macromolecules),俗称塑料(plastics)或树脂(resin),可以自由改变成分及形体样式,由合成树脂及填料、增塑剂、稳定剂、润滑剂、色料等添加剂组成。塑料的主要成分是树脂。树脂这一名词最初是由动植物分泌出的脂质而得名,如松香、虫胶等,树脂是指尚未和各种添加剂混合的高分子化合物。树脂约占塑料总重量的40%~100%。塑料的基本性能主要决定于树脂的本性,但添加剂也起着重要作用。有些塑料基本上是由合成树脂所组成,不含或少含添加剂,如有机玻璃、聚苯乙烯等。所谓塑料,其实它是合成树脂中的一种,形状跟天然树脂中的松树脂相似,经过化学手段进行人工合成,而被称之为塑料。特别是新型塑料材料的制备过程中,需要预先对塑料粒子进行烘干,采用现有的烘干设备,因烘干箱体的温度不易精确控制,塑料粒子在烘干时很容易因温度过高而焦化,加热速度不够快。
