一种电加热热风循环加热器
:本技术涉及一种电加热热风循环加热器,属于电加热设备
技术介绍
:覆膜砂是由德国克洛宁博士于二次大战期间专利技术的,其工艺过程是将粉状的热固性酚醛树脂与原砂机械混合,加热时固化。后发展成用热塑性酚醛树脂加潜伏性固化剂(乌洛托品)和润滑剂,通过一定的覆膜工艺配制成覆膜砂,当覆膜砂受热时包覆在砂粒表面的树脂熔融,在乌洛托覆膜砂品分解出的亚甲基的作用下,熔融的树脂由线性结构迅速转变成不熔融的体型结构,从而使覆膜砂固化成型,当前国内外生产树脂热法覆膜砂的方法多采用火焰加热,这不仅污染环境还降低覆膜砂强度。并损失大量的热能,热效率很低,而且砂温不易控制;而现有的电加热式加热器在加热时其时间长,且电热管均为平直设置,其利用率低。
