Silent-free thermal insulation from self-sealing masses based on a burnable additive of plant origin. Part 3. Technological features of the production of non-chamotte-free thermal insulation products based on a burnable additive with a starchy core of micellar structure
The modes of electric heating of the self-compacting mass are determined. Three periods of changes in its specific electrical resistance are noted, due to the water absorption capacity of the herbal supplement. The relationship between electrophysical processes and their influence on the compaction of the mixture is described. The scheme of raw drying according to the rate of moisture loss is considered. The selection of the firing regime was carried out taking into account the influence of gases formed during the burnout of the vegetable additive and volumetric changes in clay during sintering. The microstructure of the lightweight material is characterized by a large number of circular closed pores in the range of 0,1‒1,2 mm. Ill. 5. Tab. 3.
