In the case of a large number of external wall insulation decorative panels being flooded, how to develop small and medium-sized enterprises and how to formulate enterprise development plans. This is a very serious practical problem. Enterprises need to test customer support, so enterprises should start from the perspective of customers, really put themselves in customer service, solve customer problems, and then how to start? First of all, the main problem facing customers is how to choose external wall insulation decorative panels, which has become a problem faced by many customers. There are many manufacturers of external wall insulation decorative integrated panels, and there are many types of products. So, what kind of products do customers need?
Insulation boards, thin plastering and external wall insulation materials are mainly composed of bonding layers, insulation layers, auxiliary connectors, bottom layers, reinforcement materials and finishing layers. Insulation boards, thin plastering and external wall insulation have strict technical requirements. Its performance requirements can be summarized into six aspects: effective insulation, reliable connection, fireproof, durable, waterproof and breathable, and beautiful. On the basis of using qualified system materials, external insulation projects also require professional teams to build high-quality external insulation products in accordance with strict construction techniques. Taking polystyrene boards as an example, the construction process of insulation boards, thin plastering and external insulation is explained.
The main construction processes of external wall insulation materials are: construction preparation, surface treatment of the base layer, laying out, installation of the starting bracket, preparation of adhesives, paste and flip glass fiber mesh, paste insulation board, installation of fire barriers, insulation board repair, installation of anchor bolts. Installation, preparation of plastering mortar, special joint treatment, laying glass fiber mesh with the bottom plastering mortar, plastering mortar and plastering, and external decoration work.
After entering the site, the insulation board should be kept away from fire sources. The insulation board should be stored in a warehouse or shed. Pay attention to ventilation and moisture-proof, and do not rain. When storing in the open air, use incomplete materials covered with non-combustible materials and indicate the name of the material. Prepare with other materials and keep in a safe place. The external insulation system requires all materials to have good compatibility so that the external insulation structure is organically combined. Therefore, the system should provide external insulation materials, and the supplier should bear full responsibility for the quality of the system products.
When the materials enter the construction site, the construction site should be sampled and re-inspected as required. The re-inspected materials should be sampled and sent to witnesses for inspection. Among them, thermal conductivity, apparent density, tensile strength perpendicular to the board surface and combustion performance should be retested. The combustion performance, thermal conductivity and water absorption of the insulation area should be rechecked. The adhesive should be retested at room temperature with the normal tensile strength of cement mortar insulation board and insulation tape. The tensile strength of plaster mortar and the compression ratio of insulation board and partition should be checked at room temperature and when immersed in water. The retention of alkali fracture resistance and alkali fracture resistance should be rechecked. All materials must be used after witnessing sampling tests. Prepare external insulation construction equipment, including balance, electric stirrer, hammer or drill, ink box, wiper, yin and yang wiper, level gauge, two-meter ruler, cutter, wire brush, brown brush, etc.
1. There is no doubt that one of the main functions of the exterior wall composite board is to decorate the exterior wall.
2. The thermal insulation performance of the exterior wall insulation decorative board is of course a concern. The insulation performance is determined by the materials used in the insulation material. Such as inorganic insulation materials (such as rock wool, glass wool, etc.); organic insulation materials (such as EPS, XPS, polyurethane, etc.).
3. While paying attention to insulation performance, fire rating is also a noteworthy indicator. As an integral building decoration material, the exterior wall insulation decoration integrated board has a large construction area and is not a fireproof insulation material, which can easily cause the spread of fire. Therefore, we need to choose high-end fireproof exterior wall insulation decorative panels. Similarly, the fire rating of exterior wall insulation decorative panels is also determined by the flammability of the insulation material. The fire rating of insulation materials is divided into Class A and Class B. Class A insulation materials have good fire resistance. Class A insulation materials include: Class B insulation materials, such as rock wool boards and polyurethane composite boards: EPS exterior wall insulation boards, XPS exterior wall composite insulation boards, rigid foam polyurethane composite insulation boards, etc.
4. In addition to paying attention to the quality of the exterior wall insulation decoration integrated board products, another factor is also very noteworthy, that is, the insulation decoration integrated board during construction.
The dry hanging method of exterior wall insulation materials is also called the empty hanging method. At present, it is a new type of wall decoration construction technology. This method uses metal pendants to hang the facing stone directly on the wall or vacant on the steel frame without grouting. The principle is to set the main points on the main structure and fix the exterior wall insulation material to the building through the metal ceiling to form a stone decorative curtain wall. Through professional drilling equipment, the edge of the ceramic plate is accurately processed into a circular hole, the pin is inserted into the hole, and the ceramic plate is fixed to the keel through the connector. Because the edge of the ceramic plate has holes, it is easy to collapse, the ceramic plate loss is large, and the construction process is complicated, it has been eliminated and is basically not used.
