Insulated Exterior Pu Sandwich Panels

The surface of the Insulated Exterior Pu Sandwich Panel is a high-quality color relief surface metal plate treated by special layers. It is mainly composed of three parts: surface material, core material and inner material. It has the advantages of heat preservation, sound insulation and so on

It is made of alloy steel plate molding, after special resin high temperature coating, filled with hard polyurethane foam insulation, paste aluminum foil paper composite. Metal carved aluminized zinc insulation board is an energy-saving wall decoration building material developed in recent years. The surface is metal embossed, with a variety of patterns such as brick pattern, stone pattern and water ripple. Seven times special resin coating, more than 50 colors to choose from, and guaranteed 10 years of non-fading.​​​​​​

The plate is composed of polyurethane foam in the middle of the insulation, heat breaking layer, its internal is an independent closed bubble structure. The aluminum foil pasted on the back can effectively reflect the heat source to play the role of heat insulation, heat preservation and moisture-proof. Concave-convex splicing and groove combination, the construction is very simple. Metal carved aluminum zinc composite insulation board is a kind of high pressure resistance, moisture-proof, low thermal conductivity, beautiful, durable, energy saving, convenient construction, environmental protection integrated excellent performance building materials.

The appearance of metal wall panels breaks the complicated operation links in the traditional painting mode, realizes the excellent characteristics of simple installation and long-term use, so the specific installation method can be understood through the following.

(1) basic wall treatment: For the dirt on the wall, soft empty plaster layer and oil stains, etc. should be completely removed, and the damaged plaster layer needs to be repaired and flattened. Old walls with moss should be thoroughly cleaned with insecticide. The plastering of the external walls of new buildings shall meet the requirements of the code.

(2) Brushing interface mortar: use a rolling brush or broom to evenly brush the interface mortar or mechanical spraying. Do not miss brush, pull hair should not be too thick.

(3) Preparation of polymer bonded sand: bonding mortar: water =4.5:1 (weight ratio) ratio of water (reference ratio), use electric mixer fully and evenly, stand for 5-10 minutes, stir again can be used up, mixed mortar within 2 hours, it is strictly prohibited to have solidified mortar secondary stirring before being put into use.

(4) Check the size and wall layout according to the drawings: vertical, square and elastic thickness control line should be hung on the side wall and roof according to the thickness of the insulation decorative board, and the control line should be installed on the wall.

(5) Paste integrated board: the board coated with adhesive mortar should be immediately flat glued to the base wall, and slide in place on the wall. The operation should be gentle and evenly squeezed to ensure that the surface flatness of the decorative board pasted to the wall meets the requirements, and at any time use a 2.0m ruler for flatness correction. About 24 hours, such as mortar hardening, play "ten" and "one" font anchorage.

(6) sealant or crocheting putty crocheting: caulking first with thermal insulation material, and then with building weather sealant or caulking putty crocheting, building weather sealant or caulking putty should not be less than 3㎜ thick, glue seam should be hooked into a full, dense, continuous, uniform, no bubble concave groove.

(7) To remove the protective film and clean the surface: after the sealant is dry, the putty lifts the protective film, cleans the board, and beware of scratching the board.

(8) Acceptance: After removing the protective film and cleaning the surface, check the layout flat, vertical and square of the Yin and Yang Angle. Timely replacement of non-conforming.

The above is the detailed construction technology of metal carving board. During installation, the specific process can be understood through the above, and the influence of the external climate environment on the installation of the finished metal carving board is very limited, so you can rest assured that you can use it.
