Spray polyurethane wall temperature ![]()
Polyurethane hard foam thermal insulation material has excellent thermal insulation properties and formability, and the party has very extensive application in terms of thermal insulation refrigeration; For difficult to use mould, such as large-scale spherical tank, large diameter pipe fittings, cold storage of objects, such as, building walls and roof insulation coating, is the best way to spot spraying foam: the method is to directly spray polyurethane foam material on the surface, the material quickly foam and gel, shape into a consistent with the substrate shape of rigid polyurethane insulation thermal insulation layer.
Spraying construction technology of the main benefits include the following aspects:
(1) for the base material of various shapes, theory is at the top of the plane, elevation, or not, whether it is a round, spherical, or other irregular shape of complicated objects, can be directly implemented spraying foam processing, does not need costly mould manufacturing cost;
(2) spraying foam molding foam thermal insulation layer of the base material and shape of the object shape is consistent; No juncture, thermal insulation effect is good; Foam layer has a dense layer of external protection layer, can well protect the internal core material, but also easy to outer surface coatings and further repair;
(3) high efficiency, especially suitable for large area, abnormity object adiabatic processing, molding speed, high production efficiency.
Chemical composition and properties:
Spray type polyether composite material composed of polyether polyols, and foam agent, catalytic agent, crosslinking agent, flame retardants, such as hair bubble agent components, in accordance with the different purposes of can be divided into cold storage insulation, roof insulation waterproof, equipment, etc. Three main types.
Usually polyether composite material shows light yellow or red brown sticky and transparent liquid, no sludge and rare stiff and uneven phenomenon, no mechanical impurities.
