METHOD OF MAKING HEAT-INSULATION ARTICLES AND PROCESS LINE TO THIS END Russian patent published in 2012 - IPC B28B3/00 C04B38/06 

FIELD: process engineering.

SUBSTANCE: invention relates to construction and may be used in production of heat insulation panels from diatomite stock. Proposed method comprises preparing and feeding diatomite mix, additives and plasticisers to up articles quality, their mixing, moulding, drying and annealing. Diatomite stock delivered from quarry, sized to at least 80 mm and subjected to iron removal, is placed into heated storage room with temperature not lower than 5°C for at least 24 h, and mixed with the following additives for mix preparation: dispersed diatomite powder bearing 90% of fractions smaller than 15 mcm and moisture content of 3-8% in amount of 7-12% of mix bulk, chalk of fraction smaller than 140 mcm and moisture content not exceeding 2% in amount of 15% of mix bulk, saw dust with 90% of fractions exceeding 0.5-2 mm and moisture content not exceeding 40% in amount of 3% of mix bulk. Prepared mix moisture content is brought to 34-36%.

EFFECT: higher heat resistance.
