Building materials flame retardant coating testing machine (large
plate method)
Introduction:
The flame retardant coating testing machine (large plate method) is
used to place the fire retardant coating coated on the surface of
the combustible substrate in the flame under specified conditions
in accordance with the technical indicators and requirements
specified in the national standard GB 12441-2018 to test its flame
retardant time and flame retardant performance, so as to judge the
fire retardant effect of the coating and determine whether it meets
the relevant standards.
Main usage:
Evaluating the performance of fire retardant coatings:
The large panel method can be used to evaluate the flame retardant
properties of fire retardant coating, so as to determine whether
they are suitable for fire protection of specific buildings.
Product quality control:
In the production and sales process of fire retardant coatings, the
large panel method can be used as a quality control method to
ensure product quality.
Scientific research and development:
The large panel method can also be used for scientific research and
development of fire retardant coatings, such as exploring new
materials and new processes, and evaluating their performance.
Features:
