Problems solved by technology

The system is prone to leakage after the rock wool insulation material is added to the color steel to insulate the tank body. After the leakage, the rock wool expands and loosens when it encounters water, losing the original insulation effect, and the riveting technology used directly produces a thermal bridge. Phenomenon, color steel begins to rust and damage after about two years of normal use, and it is not easy to repair. It must be dismantled and reinstalled to achieve a good heat preservation effect
The polyurethane material used for polyurethane spraying tank insulation is a flammable insulation material, which is prone to safety hazards during construction, and is expensive, and it is not easy to repair after the system is damaged

Description

technical field [0001] The invention relates to thermal insulation materials for industrial tanks, in particular to a high-performance nano thermal insulation paste. Background technique [0002] At present, the existing industrial tank insulation mostly uses rock wool insulation material plus color steel and polyurethane spray tank insulation. The system is prone to leakage after the rock wool insulation material is added to the color steel to insulate the tank body. After the leakage, the rock wool expands and loosens when it encounters water, losing the original insulation effect, and the riveting technology used directly produces a thermal bridge. Phenomenon, color steel begins to rust and damage after about two years of normal use, and it is not easy to repair. It must be dismantled and reinstalled to achieve a good heat preservation effect. The polyurethane material used for the insulation of the polyurethane spray tank body is a flammable insulation material, which i...
