METHOD OF PRODUCING BIOLOGICAL COMPOSITE MATERIAL

摘要

FIELD: process engineering.SUBSTANCE: invention relates to production of construction materials, particularly, to fabrication of compacted wood biological composite materials. Proposed method comprises making biological composite material including biological binder and saw dust. Produced material is dried to make a mat by cold compaction and subjected to hot forming. Saw dust is mixed with biological binder based on culture broth obtained in cultivation of Leuconostoc mesenteroides bacterium on nutrient medium. Said medium consists of the mix of molasses, wastes of sugar production, and lactoserum taken in the ratio of 2:2:1 at temperature 24-26°C for 72-96 hours in static conditions with addition of liquid glass in concentration of 2.5 wt %.EFFECT: moisture-resistant nonpolluting materials without phenol compounds.1 ex
