Cause Analysis and Improvement Measures of Poor Appearance of White Circles on Sidewall of Steel-belted Radial Tire
The causes of the poor appearance of white circles on the sidewall of steel-belted radial tires were analyzed,and improvement measures were proposed.By adopting measures such as using specialized compound covering for white sidewall tires,designing the position of white compound in the sidewall reasonably,controlling the extrusion pressure of white compound and black compound during sidewall production,ensuring the surface smoothness of extruded semi-finished parts,reducing the deviation of sidewall position during building,controlling the joint overlap size according to zero deviation,and so on,and at the same time strictly controlling the production process,the problem of poor appearance of white circles on the sidewall of steel-belted radial tire had been effectively solved.
