60 \/ 100 Partes de resina de pvc. el exceso hace que el cuero sea demasiado suave, y si no es suficiente, el endurecimiento es f\u00e1cil de agrietar.<br \/>\nSoluci\u00f3n: reemplazar plastificantes resistentes a la migraci\u00f3n (como los de poli\u00e9ster) y reducir los microporos superficiales causados por la volatilizaci\u00f3n.<br \/>\nTratamiento de rellenos y aditivos:<br \/>\nCuando el contenido de agua de los rellenos como caco en el PVC duro es superior al 0,3%, el procesamiento a alta temperatura es propenso a la producci\u00f3n de burbujas; La adici\u00f3n insuficiente de estabilizadores (menosde 2 partes) desencadenar\u00e1 la descomposici\u00f3n de la resina para producir gas.<br \/>\nSoluci\u00f3n: el relleno se seca hasta que el contenido de agua sea \u2264 0,3%, y el estabilizador se agrega en una proporci\u00f3n de 2 &#8211; 3 partes.<br \/>\n2. dificultades del proceso<br \/>\nDefectos de tratamiento de tela base:<br \/>\nLa pulpa de la tela base no se retira completamente (la temperatura de cocci\u00f3n es inferior a 90 \u00b0 c o el tiempo es inferior a 30 minutos) y el aceite residual reduce la adherencia de la capa de pvc.<br \/>\nSoluci\u00f3n: cocinar a 100 \u00b0 C durante 60 minutos + aplicar la capa inferior para fortalecer la adherencia.<br \/>\nDesaf\u00edo de uniformidad de recubrimiento:<br \/>\nEl error de distancia de la esp\u00e1tula es superior a 0,1 mm, lo que resulta en un espesor desigual (por ejemplo, la fluctuaci\u00f3n real del cuerpo de cuero objetivo de 0,5 mm es de \u00b1 0,2 mm).<br \/>\nSoluci\u00f3n: el PVC blando utiliza tornillos de bajo Corte para reducir el da\u00f1o t\u00e9rmico; El PVC duro eleva la contrapresi\u00f3n del tornillo a 22 MPA para mejorar la densidad de fusi\u00f3n.<br \/>\nControl de secado y plastificaci\u00f3n:<br \/>\nLa zonificaci\u00f3n inadecuada de la temperatura del horno (por ejemplo, la zona de prehorneado es superior a 80 \u00b0 c) provoca descamaci\u00f3n de la superficie, y los compuestos vol\u00e1tiles internos no pueden expulsarse para formar burbujas de aire.<br \/>\nSoluci\u00f3n: PVC blando: 60 &#8211; 80 \u2103 precotizado durante 3 &#8211; 5 minutos \u2192 150 &#8211; 180 \u2103 horneado final durante 5 &#8211; 8 minutos; PVC duro: la actualizaci\u00f3n simult\u00e1nea de la bomba de vac\u00edo de dos etapas mejora la eficiencia de bombeo en un 40%.<br \/>\n3. medidas clave para la optimizaci\u00f3n de la calidad<br \/>\nMonitoreo en l\u00ednea: medidor de humedad infrarrojo integrado + sensor de presi\u00f3n de fusi\u00f3n para advertir la desviaci\u00f3n del proceso en tiempo real.<br \/>\n\u200c m\u00e9todo de investigaci\u00f3n r\u00e1pida: reemplazar las materias primas secas para verificar el origen de las burbujas; Cierre el sistema de vac\u00edo a corto plazo para comparar el n\u00famero de burbujas.<br \/>\nColaboraci\u00f3n entre procesos: el intervalo entre la base y el proceso de recubrimiento es \u2264 10 minutos para evitar la oxidaci\u00f3n de la interfaz.<br \/>\nA trav\u00e9s del refinamiento de las materias primas, la estandarizaci\u00f3n de los par\u00e1metros del proceso y la actualizaci\u00f3n de los equipos ambientales, se puede romper sistem\u00e1ticamente el cuello de botella de la producci\u00f3n de cuero de pvc.<\/p>\n<p><img decoding=\"async\" class=\"lazyload alignnone size-full wp-image-9775\" src=\"http:\/\/www.longyuen.com\/wp-content\/uploads\/2025\/08\/ce4870c86c9148a5a9424ede9fb767eb.jpg\" data-orig-src=\"http:\/\/www.longyuen.com\/wp-content\/uploads\/2025\/08\/ce4870c86c9148a5a9424ede9fb767eb.jpg\" alt=\"\" width=\"800\" height=\"800\" srcset=\"data:image\/svg+xml,%3Csvg%20xmlns%3D%27http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%27%20width%3D%27800%27%20height%3D%27800%27%20viewBox%3D%270%200%20800%20800%27%3E%3Crect%20width%3D%27800%27%20height%3D%27800%27%20fill-opacity%3D%220%22%2F%3E%3C%2Fsvg%3E\" data-srcset=\"https:\/\/www.longyuen.com\/wp-content\/uploads\/2025\/08\/ce4870c86c9148a5a9424ede9fb767eb-66x66.jpg 66w, https:\/\/www.longyuen.com\/wp-content\/uploads\/2025\/08\/ce4870c86c9148a5a9424ede9fb767eb-150x150.jpg 150w, https:\/\/www.longyuen.com\/wp-content\/uploads\/2025\/08\/ce4870c86c9148a5a9424ede9fb767eb-200x200.jpg 200w, https:\/\/www.longyuen.com\/wp-content\/uploads\/2025\/08\/ce4870c86c9148a5a9424ede9fb767eb-300x300.jpg 300w, https:\/\/www.longyuen.com\/wp-content\/uploads\/2025\/08\/ce4870c86c9148a5a9424ede9fb767eb-400x400.jpg 400w, https:\/\/www.longyuen.com\/wp-content\/uploads\/2025\/08\/ce4870c86c9148a5a9424ede9fb767eb-600x600.jpg 600w, https:\/\/www.longyuen.com\/wp-content\/uploads\/2025\/08\/ce4870c86c9148a5a9424ede9fb767eb-768x768.jpg 768w, https:\/\/www.longyuen.com\/wp-content\/uploads\/2025\/08\/ce4870c86c9148a5a9424ede9fb767eb.jpg 800w\" data-sizes=\"auto\" data-orig-sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Hay muchas  [&#8230;]<\/p>\n","protected":false},"author":1,"featured_media":9775,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"om_disable_all_campaigns":false,"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"_uf_show_specific_survey":0,"_uf_disable_surveys":false,"footnotes":""},"categories":[238],"tags":[435],"class_list":["post-9781","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news-es","tag-cuero-de-pvc"],"aioseo_notices":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.2 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>\u00bf\u00bf cu\u00e1les son las dificultades t\u00e9cnicas en la producci\u00f3n de cuero de pvc? - Wenzhou Longyuan International Trade Co., Ltd.<\/title>\n<meta name=\"description\" content=\"Discover premium fabrics at Longyuan.
