Product Name：PBO ROLLER SLEEVE
When the aluminum profile is extruded through the die, the
temperature of up to 5500 ℃, with the general material can not be
long time to bear such a high temperature. PBO fiber is a kind of
high temperature resistant material, its maximum temperature
resistance can reach 600. PBO fiber and para aramid fiber layer
acupuncture and resistance temperature felt drum the most suitable
for use in aluminum profile extrusion machine of a feed opening and
sliding introduced on.
PbO drum using the key to life is the density of the surface of PBO
rather than its thickness, strong dense PbO layer can ensure the in
successive 550 DEG C high temperature environment, and to withstand
the wear and tear of sharp shape of aluminum. Low density of PBO
drum due to PBO fiber and the underlying para aramid fiber with
closely enough, thus in continuous wear will make the surface of
PBO into blocks into a layer of wear, once the PBO fiber layer is
worn, the service life of the bottom of the para aramid fiber up to
more than 15 days.
Because PBO is a kind of metal fiber, its strength is very high (20
times the steel), high PBO density will cause difficulties in the
production process, such as broken needles is a biggest technical
problems. After years of practice and research, the most reasonable
production technology and the best balance point of PBO layer
thickness and density have been mastered.
Can provide you with special resin hardening process, improve
product wear resistance, prolong the service life.
