Electric heating regimes are determined for mixture self-compaction. Three periods of change in its specific electrical resistance are noted due to the water absorption capacity of the plant supplement. The relationship between electrophysical processes and their influence on mixture compaction is described. A scheme of drying raw material according to the moisture loss rate is considered. A firing regime is selected taking into account the influence of gases formed during vegetable additive burn-off and volumetric changes in clay during sintering. The microstructure of lightweight material is distinguished by a large number of circular closed pores in the range of 0.1 – 1.2 mm.

基于植物来源的燃尽添加剂的自固结混合物的无沙莫特的绝热。第3部分。基于具有胶束结构的淀粉芯的燃尽添加剂的无烟煤隔热材料的生产特性1

确定电加热方式以实现混合物的自压缩。由于植物补充剂的吸水能力,注意到其比电阻的三个变化期。描述了电物理过程及其对混合物压实的影响之间的关系。考虑根据水分损失率干燥原料的方案。选择一种烧制方案时要考虑到植物添加剂烧尽过程中形成的气体的影响以及烧结过程中粘土的体积变化。轻质材料的微观结构的特点是在0.1-1.2 mm范围内有大量的圆形封闭孔。
