Causes for substandard quality of rubber belt
Author:admin Source:Original Updated:2013-7-13

Conveyor belt production and processing is not perfect, there is always defective produce, and even out of the conveyor belt production can not meet the standard, then the reasons for non-compliance causing belt are what it?

   
1, mainly due to the composition of the decision conveyor belt is made of rubber processing, conveyor belts in colder weather becomes more rigid, used in this weather conveyor belt will greatly reduce the life; while relatively warm weather, the conveyor belt will become more flexible, so that we can improve belt life and reduce warm-up boot time and improve work efficiency.

   
(2) special zonal elongation of yarn canvas belt body caused by excessive contraction of the mold quickly narrowed. Often used in ordinary canvas roughly parallels the structure there are so few, one polyester / cotton, polyester filament; Second, pure polyester; Third DTY plus cotton; fourth is pure DTY; Fifth miscellaneous yarn and cotton; six is ​​a pure hybrid yarn. The first two heat-shrinkable weft structure relatively stable, low. The rest of the weft structure shrink and instability, especially DTY, not only shrink large and sticky and force a minimum, leading to narrowing the width of the main belt body. Bring your own canvas width inconsistent, molding good grasp of the whole is inconsistent with the core width; by bringing manufacturing process is not standardized canvas, canvas width also varies in width, covered in molding edge width narrowing or covered The phenomenon is extremely common, for molding work has brought great inconvenience, but this is the result after vulcanization of conveyor width inconsistency is an important factor.

3 bezel width is not standardized or g over horn. The original board design with a face width less when 5mm, so even with the use of the material does not shrink the body, curing the finished product will also narrower; during vulcanization time and time again during the operation led to the emergence of the stereotype baffle polished several times the width of the baffle varies in width, the roller is caused by a wide section of narrow reasons.

4 hot plate welding under non-standard or stopper excessive wear. Block fast in use sometimes off phenomenon, maintenance man in the welding due to lack of precision measurement and welding of expansion and contraction can also lead to non-standard layout; in there, prolonged use can also cause wear plate head plate tail block fast darken width increases, resulting in inconsistencies within and outside width.
