FIELD: production of porous molded articles.
SUBSTANCE: powder-like agents are mixed with water and are molded in mold for making blanks. Powder-like agents are mixed with water in the amount of 5-40 mass-% of water and salt containing hydration water in the amount of up to 15 mass-% for entire mixture. Blanks thus obtained are carefully strengthened by heating to ensure contact between grains of powder without keratosis of starch and cellulose derivatives or without film forming in case of powders of repeatedly dispersing polymers.
EFFECT: avoidance of separation and dust; enhanced efficiency.
