HDE
We use DuPont nylon 66 fiber, which is produced from the source. Through a special production process, the internal structure of the non-woven fabric is rearranged in multiple crosses, making it wear-resistant, tough, friction-resistant, more absorbent, and has good recovery. SGS certification ensures the stability of product quality.
Main parameters of HDE roller
Temperature resistance | ≤200℃ |
Normal length | 500-5500mm |
Normal outer diameter | φ120-500mm |
Hardness control | 55-100 shore A |
PH value range | 2-10 |
Line pressure and winding calculation
E: Young's modulus (elastic modulus) of steel (Kgf/cm3)
I: moment of inertia (cm4)
Solid shaft:
R=shaft radius (cm)
Tube axis:π/4*(R4-r4)
R=tube outer diameter (radius)
r=tube inner diameter (radius)
W: Line pressure (kgf/cm)
(2*P+roller weight)/roller surface length
Winding amount δ={(5*W*L4)/(24*E*I)}*(1+12/5*a/L)
Roller repair process
1. Old roller inspection
2. Confirmation of repair plan
3. Replacement of damaged parts
4. Turning and grinding of roller surface
5. Performance inspection
