METHOD OF GLUING ROLL MATERIALS WITH ADHESIVE LAYER Russian patent published in 2002 - IPC

FIELD: construction engineering, particularly, methods of gluing of roll materials in roofing and waterproofing. SUBSTANCE: method is based on surface heating of roll fused materials by infrared radiation to depth of 0.5-1.0 mm and temperature of 110-180 C with radiation wave length of 1.8-2.4 mcm and radiation density of 12-18 W/sq.cm. Rolling down is carried out with unit pressure of 0.035-0.065 MN/sq.m. As radiation wave length increases and density of infrared radiation reduces, depth of material heating rises. EFFECT: increased rate and quality of work. 2 ex
