P: \u00bfC\u00f3mo se compara el coste total de propiedad entre el PU moldeado por fundici\u00f3n y el moldeado por inyecci\u00f3n?<\/p>\n\n\n\n
R: La elecci\u00f3n incorrecta del PU aumenta su coste total de propiedad en 30%+. Las piezas de fundici\u00f3n duran 3 veces m\u00e1s, lo que reduce los costes de sustituci\u00f3n y los tiempos de inactividad.<\/p>\n\n\n\n

P: \u00bfPuede el PU moldeado por inyecci\u00f3n igualar la resistencia qu\u00edmica del PU fundido?<\/p>\n\n\n\n
R: No. La estructura totalmente reticulada del PU fundido resiste el aceite, el combustible y los disolventes mucho mejor que el PU de inyecci\u00f3n de cadena rota.<\/p>","protected":false},"excerpt":{"rendered":"
Last November, I stood in a coal washing plant in northern China at 3 a.m. Their main coal conveying line had been down for 8 hours. The root cause? 16 injection-molded PU coated conveyor rollers that delaminated mid-operation, seized up, and tore a 12-meter gash in the heavy-duty belt. I\u2019ve seen hundreds of these cases: […]<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_seopress_robots_primary_cat":"","_seopress_titles_title":"","_seopress_titles_desc":"","_seopress_robots_index":"","footnotes":""},"categories":[48,3],"tags":[],"class_list":["post-3047","post","type-post","status-publish","format-standard","hentry","category-blog","category-newsblog"],"_links":{"self":[{"href":"https:\/\/pepsenpu.com\/es\/wp-json\/wp\/v2\/posts\/3047","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pepsenpu.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/pepsenpu.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/pepsenpu.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/pepsenpu.com\/es\/wp-json\/wp\/v2\/comments?post=3047"}],"version-history":[{"count":12,"href":"https:\/\/pepsenpu.com\/es\/wp-json\/wp\/v2\/posts\/3047\/revisions"}],"predecessor-version":[{"id":3063,"href":"https:\/\/pepsenpu.com\/es\/wp-json\/wp\/v2\/posts\/3047\/revisions\/3063"}],"wp:attachment":[{"href":"https:\/\/pepsenpu.com\/es\/wp-json\/wp\/v2\/media?parent=3047"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/pepsenpu.com\/es\/wp-json\/wp\/v2\/categories?post=3047"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/pepsenpu.com\/es\/wp-json\/wp\/v2\/tags?post=3047"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
