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.
