A traditional
metal bridge surface corrosion layer thickness is small,
easily damaged during transportation, installation and fine
holes on the surface, corrosive gas through the hole easily
into the structure layer affect the preservative effect;
strong, non-metallic cable tray antiseptic properties, but
not enough mechanical strength. Based on these
circumstances, I developed a composite epoxy composite cable
tray: composite epoxy cable tray metal skeleton, not only to
retain the characteristics of the original composite epoxy
cable tray, while increasing the mechanical strength ,
carrying large diameter cables, bridge span up to 15 meters.
Third, in order to solve the metal and nonmetal caused
delamination problems due to different coefficients of
expansion between the metal and nonmetal Uploaded bonding
layer; IV easy to aging, in order to solve the easy powder,
the problems molded protective layer has a special role in
the anti-light, in the surface of the bridge; five composite
epoxy composite cable tray identified by the authority, life
in more than 30 years, this product has been used for 15
years, not signs of fading and aging. In six, cable tray,
including bridge main tray cover, both of which are layered
structure between the layers by molding closely integrated
into one structure of the bridge body and bridge cover layer
from the outside in are as follows a protective layer, a
fireproof layer, corrosion protective layer, a protective
layer. The filler is mainly aluminum hydroxide, flame
retardant and the other, when the external fire and local
cable fire, water vapor, volatile extinguish a fire source
and prevent the spread of flame, reducing the temperature of
the cable environment ensure smooth cable within a certain
time (up to N3 level), the cable tray has a high fire
performance, space efficient, beautiful appearance,
anti-corrosion properties.
