main feature:
1. Polyurethane foam has low thermal conductivity, is not easy to absorb water, has high strength and is resistant to corrosion.
2, spraying polyurethane rigid foam wall insulation is based on A material (isocyanate) plus B material (polyol, foaming agent, catalyst, flame retardant, etc.) by high-pressure foaming equipment on-site spray foaming into insulation layer, with polymer The dry-mixed mortar is an overcoat layer, and the fiberglass mesh is used as a reinforcing layer for the external wall insulation system. The finish layer is suitable for coatings, tiles, and elastic coating.
The polyurethane rigid foam is seamlessly bonded and has a strong integrity, and it is very firmly bonded to the base surface (ç ¼, mortar, red brick, block, wood, steel, glass, etc.).
3, the cover layer has no cracking, waterproof, impact resistance, anti-aging properties
4. The system life can be more than 25 years.
Construction process:
Base treatment-----spray polyurethane rigid foam----grinding----wiping polymer dry-mixed mortar----pressing glass fiber mesh---covering (polymer dry-mix mortar)
The main advantages of the spray application process include the following:
(1) For substrates of various shapes, whether it is a plane, a façade or a top surface, whether it is a circular, spherical or other irregularly shaped complex object, it can be directly spray-foamed without expensive molds. Manufacturing costs;
(2) The shape of the foamed foamed insulation layer is consistent with the shape of the substrate; no joints, good thermal insulation effect; a dense protective skin layer on the outside of the foam layer, which can better protect the inner core material, and is also easy Coating and further repairing the outer surface of the paint;
(3) High production efficiency, especially suitable for the heat treatment of large-area and special-shaped objects, fast forming speed and high production efficiency. Spray-type polyether composition is composed of polyether polyol, foam stabilizer, catalyst, trainer and flame retardant. , foaming agent and other components.
(4) Usually, the polyether composition is a pale yellow or brownish red viscous transparent liquid, free of coagulum and thick matter and unevenness, and no mechanical impurities.
Construction points:
1) The base layer is leveled (in accordance with the requirements of the specification). Before spraying, remove the loose parts of the base layer, floating ash, dirt, block the eyes of the scaffold, install the embedded parts, the base layer must be dry, and the water content is ≤8%.
2) Heavy wind (>4 grade), below 0 °C, raining shall not be applied.
3) Before spraying, the doors and windows, adjacent walls, ground pedestrians and vehicles must be protected from any pollution. Operators should wear protective clothing, protective helmets and protective glasses.
4) Layered spraying, each layer shall not exceed 2cm, and the error shall not exceed ±5mm.
5) The grinding should be fine and flat, and the error should not exceed ±2mm.
6) Do safe operation measures, prevent falling from high altitude, prevent electric shock, and carefully check the scaffolding tools, lifting equipment, grinding equipment and spraying equipment. Operators must wear safety belts, safety ropes, safety helmets and full-time safety officers.
