AGENT FOR FIRE- AND BIOPROTECTION OF WOOD AND WOOD-BASED MATERIALS

摘要

FIELD: chemistry. ^ SUBSTANCE: agent is a mixture of potassium fluorosilicate and a surfactant, with the following ratio of components in wt %: potassium fluorosilicate 97-99, sodium sulphonate 1-3. Potassium fluorosilicate is a foundry production waste formed from etching out castings from rods, removing the aluminised layer from the cast moulding production site. The surfactant used is sodium sulphonate. ^ EFFECT: ensuring high efficiency of fire- and bioprotection with low consumption of the saturating compound and low cost owing to use of cheaper raw material. ^ 1 tbl, 9 ex
