los fallos de los rodillos rara vez se producen en un momento oportuno. En operaciones log\u00edsticas de alta velocidad que funcionan las 24 horas del d\u00eda, un componente averiado puede crear una reacci\u00f3n en cadena en toda una l\u00ednea.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Repeated polyurethane delamination on a sorting conveyor is a symptom, not a complete diagnosis. The underlying cause may involve heat build-up, bond preparation, contamination, geometry, overload or a combination of factors.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">En lugar de suministrar otro rodillo de repuesto, comenzamos con un an\u00e1lisis de fallos.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">El objetivo era sencillo: identificar por qu\u00e9 fallaban los rodillos y determinar si el problema proven\u00eda de la selecci\u00f3n de materiales, los m\u00e9todos de uni\u00f3n o los procesos de fabricaci\u00f3n.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The following workflow explains how to diagnose the failure, redesign the roller and define a validation plan without assuming that one material change will solve every application.<\/p>\n\n\n\n<figure

high speed, repeated compression can generate internal heat through hysteresis.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If heat is not dissipated, it can accelerate changes in the polyurethane and bond system.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Temperature evidence must be confirmed with operating measurements and bond-line inspection rather than inferred from delamination alone.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Para aplicaciones con ciclos continuos, la hist\u00e9resis adquiere m\u00e1s importancia de lo que muchos compradores creen.<\/p>\n\n\n\n<p

Shore ideal para los rodillos industriales de poliuretano?<span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>A:<\/strong> There is no single ideal range. Select hardness from load, contact area, required deformation, traction, speed, floor or belt surface and duty cycle. Ask the supplier to confirm the proposed grade and tolerance on the drawing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Q2_Polyurethane_rollers_vs_rubber_rollers_Which_is_better_for_heavy-duty_applications\"><\/span>P2: Rodillos de poliuretano frente a rodillos de caucho: \u00bfCu\u00e1l es mejor para aplicaciones pesadas?<span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>A:<\/strong> Neither is universally better. Polyurethane can offer useful abrasion, load and chemical-resistance options, while rubber may be preferred for heat dissipation, flexibility or a particular friction requirement. Compare both materials against the actual load, speed, temperature, media and maintenance target.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Q3_What_causes_polyurethane_to_delaminate_or_peel_away_from_a_metal_core\"><\/span>Q3: What causes polyurethane to delaminate or peel away from a metal core?<span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>A:<\/strong> Delamination can result from contamination, inadequate surface preparation, an incompatible bonding system, cure deviations, excessive heat build-up, overload, edge stress or corrosion.

The worn covering is removed, the core is prepared and the new polyurethane is bonded and cast to the approved drawing.
