Nichtmetallische Verbundwerkstoffe Multi Materials Idlers

The conventional operating of the rollers will directly affect the transportation quantity and quality of cargo. On the basis of professional standards MT821-1999 of Belt Conveyor for Coal Mines-ldlers-Technical Specification, we use Polymer Composite as the main material. The idler was processed through toughening ,strengthening,anti-aging,antistatic and flame-retardant , then goes through high temperature mould pressing a former. Not only our product has the advantages of antistatic,corrosion resistance,flame-retardant,lightweight ,efficiently start-up power,but also has low inertia braking power,lower noise, excellent sealing performance and long service life and so on. The idler applies both aluminum alloy and engineering plastics labyrinth seal, which have good performance of sealing. Studies show promising results that sealing effect may increase by 300% than nylon. Product Characteristic 1.Lightweight and Convenient Replacing The main material Polymer Composite is made of fine-quality pure cotton and high-molecular resins. Net weight of our idler is1.4-2.0kg, a decline of one-third as compared with the previous ones. It is decreased labor intensity and improved productivity effect. 2.Long Service Life and Non-Maintenance The roller has the merits of steady operation, a maintenance free, long life, maintenance free and reducing enterprise cost. 3.Excellent Corrosion Resistance and Better Sealed Polymer Composite Materials Idler has lower demand of environmental condition; which withstands the corrosion of acid, alkali salt. We adopt a new one step method producing technology of sealing structure, having a strong water resistance and good dustproof performance. 4. It is really featured of heat curing solidification and high-temperature or low- temperature resisting. Our idler can deal with all kinds of complicated situations and environment temperatures, which is not distortion under abnormal environmental temperature. 5. Flame Retardant and Antistatic Property The polymer complex materials contents flame retardant agent,strength agent and antistatic agent, when the rollers are collided that can not create sparks. It is best fit for chemical industry ,fuel gas and mine shaft and many other inflammable and explosive dangerous places. 6.Good Fatigue Resistance and Impact Resistance At long period of excessive loaded circumstances, Composites Materials Idler has better fatigue strength than metal idler. It can be used more than 20000h and better mechanical strength than ordinary carbon steel. 7.Reduce Abrasion of Rubber Belt and Friction Resistance Our idler has the advantages of light weight, less friction, low noise and smoothly working that prolong the rubber belt the lifetime. On conveyance occasions, the rubber belt was not worn, or even belt joint not loss. Technology Parameters 1.
