What matters needing attention in the application of EPS color steel sandwich panel
|EPS wall panel and roof panel|
1. Quality problems
In terms of quality problems, EPS color steel sheet sandwich panel are most likely to have problems in bond strength, surface density, peeling performance, size deviation, etc. The poor bond strength results in that the sandwich panel cannot bear enough external force, which is easily damaged and torn. In the actual installation process, the sandwich panel cannot bear enough mechanical force and the difference of surface density will lead to conductivity. The sandwich panels have insufficient flexural properties and cannot withstand pressure. For example, when they are used in roof sandwich panels and are accidentally weighted, they are liable to cause indoor personal injury. The enclosure structures used in light composite houses cannot withstand greater thrust. In fact, as long as the manufacturers organize the original materials production according to JC689, 1998 (Metal Surface Polystyrene Sandwich Panels) standard, surface density indicator is very easy to achieve.
If the peeling performance is poor, the service life of the cold storage with sandwich panel insulation will not meet the design requirements. The economic interests of consumers will be seriously harmed. Size deviation will reduce specifications, increase usage, increase construction costs. The deviation of length, width and thickness of the standard is regulated. Many Enterprises The standard is not understood, and the product specifications and models reported are quite different from the actual production. For example, the standard width series is 1150 mm, 1200 mm, and the allowable deviation is (+2 mm), while some manufacturers submit 1150 mm specifications to 1200 mm. In addition, some manufacturers are prone to unqualified size deviation due to inadequate cutting accuracy of equipment.

2. Construction problems
Attention should be paid to whether the connection between the steel framework and the EPS color steel sandwich panel is firm enough, whether the connection is covered with fire-proof paint or not. Attention should be paid to the steel structure, whether the EPS color steel sandwich panel building is equipped with lightning rods and whether there is a good grounding point.
3. Scope of application
Because the spontaneous combustion and ignition temperature of EPS are 495 C and 370 C respectively, the EPS color steel sandwich panel cannot decorate the kitchen, cannot be used in high-power lamps and lanterns, cannot be close to the place where the power consumption is large and the frequency is high. EPS color steel sandwich panel cannot be used as temporary low, high-voltage distribution room building material.EPS color steel sandwich panel can be used as the envelope structure material of clean workshop.
As a new building energy-saving material, EPS color steel sandwich panel is widely used in the construction industry. How to use EPS color steel sandwich panel regularly under the condition of energy-saving and safety on the basis of learning fire lessons is still a big topic for fire fighters to study and explore in the future.
