Model 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.
