Im Vergleich zum Einschneckenextruder ist der Doppelschneckenextruder<\/a> haben viele Vorteile.<\/p>\n\n\n\n

1. gesteigerte Vielseitigkeit<\/strong>
Die zwei parallel angeordneten Schnecken erm\u00f6glichen unterschiedliche Konfigurationen und variierende Bedingungen in den verschiedenen Extruderzonen. Daher gibt es verschiedene Arten von Doppelschneckenextrudern mit unterschiedlichen Betriebsmechanismen, die f\u00fcr verschiedene Anwendungen eingesetzt werden k\u00f6nnen.
2. geringere Neigung zur \u00dcberhitzung<\/strong>
Bei Einschneckenextrudern entsteht durch die Erh\u00f6hung der Schneckendrehzahl W\u00e4rme, die Materialien, die empfindlich auf eine erh\u00f6hte Temperatur reagieren, zersetzen kann. Dieses Problem wird bei Doppelschneckenextrudern vermieden, da die W\u00e4rme durch externe Quellen gesteuert und unabh\u00e4ngig von der Schneckendrehzahl erzeugt wird.\u00a0
3. verk\u00fcrzte Verweildauer<\/strong>
Die Verweildauer eines Stoffes im Extruder ist k\u00fcrzer, vor allem wegen der im Vergleich zum Einschneckenextruder relativ schnellen Schmelzzeit. Ein typischer Extrusionsprozess dauert nur zwischen f\u00fcnf und zehn Minuten.
4. selbstreinigend<\/strong>
Der Doppelschneckenextruder verf\u00fcgt \u00fcber ineinandergreifende, gleichlaufende Schnecken, wobei der Schneckengang einer der Schnecken die Basis der parallelen Schnecke abstreift, was eine vollst\u00e4ndige Entleerung des Ger\u00e4ts gew\u00e4hrleistet und die Menge des am Ende einer Charge verschwendeten Produkts reduziert.
5. erh\u00f6hte Flexibilit\u00e4t<\/strong>
Mit der Doppelschnecke lassen sich die Prozessparameter einfach und stufenlos regeln, je nach gew\u00fcnschter Extrusionsrate oder Mischfunktion.\u00a0
6. verbessertes Mischen<\/strong>
Die ineinandergreifenden gleichlaufenden Schnecken im Doppelschneckenextruder erm\u00f6glichen eine bessere Durchmischung. Es kann eine von zwei Mischungsarten erreicht werden: die distributive oder die dispersive Mischung. Die erste Art erm\u00f6glicht eine gleichm\u00e4\u00dfige Vermischung und einen begrenzten Abbau der Stoffe. Beim dispersiven Mischen hingegen wird der Feststoffbereich in einen feineren Zustand aufgespalten.<\/p>\n\n\n\n

Compared with Single screw extruder, the twin screw extruder have many advantages. 1.Increased versatilityThe two screws mounted in parallel enables different configurations and varying conditions in the different extruder zones.therefore,Various types of twin-screw extruders available with different operating mechanisms that can be employed for different applications.2.Lower tendency to overheatIn the single screw extruder, increasing the […]<\/p>\n","protected":false},"author":1,"featured_media":105,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"unboxed","site-sidebar-style":"unboxed","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[11],"tags":[],"class_list":["post-64","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-product-introduction"],"_links":{"self":[{"href":"https:\/\/extruder-lab.com\/de\/wp-json\/wp\/v2\/posts\/64","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/extruder-lab.com\/de\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/extruder-lab.com\/de\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/extruder-lab.com\/de\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/extruder-lab.com\/de\/wp-json\/wp\/v2\/comments?post=64"}],"version-history":[{"count":4,"href":"https:\/\/extruder-lab.com\/de\/wp-json\/wp\/v2\/posts\/64\/revisions"}],"predecessor-version":[{"id":917,"href":"https:\/\/extruder-lab.com\/de\/wp-json\/wp\/v2\/posts\/64\/revisions\/917"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/extruder-lab.com\/de\/wp-json\/wp\/v2\/media\/105"}],"wp:attachment":[{"href":"https:\/\/extruder-lab.com\/de\/wp-json\/wp\/v2\/media?parent=64"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/extruder-lab.com\/de\/wp-json\/wp\/v2\/categories?post=64"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/extruder-lab.com\/de\/wp-json\/wp\/v2\/tags?post=64"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
