1. In construction, the first thing to consider is the bearing capacity of the wall and the construction ability of the workers. The phenolic board can not only be used in traditional external wall insulation systems but also can be combined with a facing layer to make integrated insulation and decoration board. It can also be used to construct a traditional EPS/XPS/PU external wall insulation system fire isolation belt and used as a curtain wall. Fire-prevention thermal insulation materials, thermal insulation materials in fire doors, and fire-prevention thermal insulation materials for low or high-temperature occasions. Phenolic insulation board is easy to make: it can be constructed on-site according to user needs; it is clean and hygienic; the surface of the sandwich board is made of aluminum foil to ensure the sanitation of the air duct, the resistance is small along the way, and the air quality is high, so the product is called environmental protection Conveyor.

Because the product is made of aluminum foil (phenolic foam) aluminum foil, it has good sound insulation and shock resistance, warmth retention, flame retardancy, and energy-saving characteristics, so that it can reduce operating costs. The most important thing is that the phenolic insulation board is a simple and convenient building material, which effectively improves the progress of the project.

2. According to the design requirements, paste or hang the surface of the phenolic insulation board on the reinforcement net. Its surface area is slightly larger than the width of the reinforcement net. It is suitable for the bottom layer of anti-cracking mortar. The thickness of the mortar is about Intern or 3nmm, the steel mesh is set on it, the convex surface of the steel mesh is inside it, and then anchored with an anchor rod, and then flattened from the middle to the periphery of the reinforcement mesh with a scraper, making it close to the bottom layer of the anti-cracking mortar.

After the test, before the bottom anti-cracking mortar sets, apply the anti-cracking mortar to the surface. Anti-crack mortar plastering should be naturally disconnected at expansion joints, yin and yang corners, platforms, etc., to facilitate subsequent lap construction. When the continuous wall needs to be stopped, the surface mortar should not completely cover the laid reinforced mesh, it should step slope stubble with rubbed layer, and the stubble spacing should not be less than 150, and the deviation of the overlapping flatness of the reinforced mesh should not be exceeded.

To sum up, this is an introduction to the construction operation and acceptance knowledge of phenolic board insulation materials. The phenolic board can not only be used in a traditional external wall insulation system but also can be combined with a facing layer to make integrated insulation and decoration board. It can also be used to construct a traditional EPS/XPS/PU external wall insulation system fire isolation belt and used as a curtain wall. Fire-prevention thermal insulation materials, thermal insulation materials in fire doors, and fire-prevention thermal insulation materials for low or high-temperature occasions.

The phenolic board has strong corrosion resistance and will not undergo structural changes in sunlight and rain for a long period of time. The environmental protection meets my country's environmental protection requirements and is an excellent product material.
