Par rapport \u00e0 l'extrudeuse \u00e0 vis unique, l'extrudeuse \u00e0 vis unique extrudeuse \u00e0 double vis<\/a> pr\u00e9sentent de nombreux avantages.<\/p>\n\n\n\n

1. polyvalence accrue<\/strong>
Les deux vis mont\u00e9es en parall\u00e8le permettent diff\u00e9rentes configurations et des conditions variables dans les diff\u00e9rentes zones de l'extrudeuse. Il existe donc plusieurs types d'extrudeuses \u00e0 double vis avec diff\u00e9rents m\u00e9canismes de fonctionnement qui peuvent \u00eatre utilis\u00e9s pour diff\u00e9rentes applications.
2.une moindre tendance \u00e0 la surchauffe<\/strong>
Dans l'extrudeuse monovis, l'augmentation de la vitesse des vis produit de la chaleur qui peut d\u00e9grader les mat\u00e9riaux sensibles \u00e0 une temp\u00e9rature \u00e9lev\u00e9e. Ce probl\u00e8me sera \u00e9vit\u00e9 avec les extrudeuses \u00e0 double vis, car la chaleur est contr\u00f4l\u00e9e par des sources externes et produite ind\u00e9pendamment de la vitesse des vis.\u00a0
3. diminution du temps de s\u00e9jour<\/strong>
La dur\u00e9e pendant laquelle une substance reste dans l'extrudeuse est r\u00e9duite, principalement en raison d'un temps de fusion relativement rapide par rapport \u00e0 celui de l'extrudeuse \u00e0 vis unique. Un processus d'extrusion typique ne dure que cinq \u00e0 dix minutes.
4. autonettoyage<\/strong>
Les extrudeuses \u00e0 double vis ont des vis co-rotatives qui s'engr\u00e8nent, la vol\u00e9e de l'une des vis essuie la base de la vis parall\u00e8le, ce qui assure une vidange compl\u00e8te du dispositif et r\u00e9duit la quantit\u00e9 de produit perdue \u00e0 la fin d'un lot.
5. flexibilit\u00e9 accrue<\/strong>
Avec la double vis, les param\u00e8tres du processus peuvent \u00eatre facilement et continuellement contr\u00f4l\u00e9s, en fonction du taux d'extrusion ou de la fonction de m\u00e9lange souhait\u00e9s.\u00a0
6. Am\u00e9lioration du m\u00e9lange<\/strong>
Les vis co-rotatives enchev\u00eatr\u00e9es de l'extrudeuse bi-vis permettent un meilleur m\u00e9lange. Deux types de m\u00e9lange sont possibles : le m\u00e9lange distributif et le m\u00e9lange dispersif. Le premier type permet un m\u00e9lange homog\u00e8ne et une d\u00e9gradation limit\u00e9e des substances. \u00c0 l'inverse, dans les processus de m\u00e9lange dispersif, le domaine solide est d\u00e9compos\u00e9 en un \u00e9tat plus fin.<\/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\/fr\/wp-json\/wp\/v2\/posts\/64","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/extruder-lab.com\/fr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/extruder-lab.com\/fr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/extruder-lab.com\/fr\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/extruder-lab.com\/fr\/wp-json\/wp\/v2\/comments?post=64"}],"version-history":[{"count":4,"href":"https:\/\/extruder-lab.com\/fr\/wp-json\/wp\/v2\/posts\/64\/revisions"}],"predecessor-version":[{"id":917,"href":"https:\/\/extruder-lab.com\/fr\/wp-json\/wp\/v2\/posts\/64\/revisions\/917"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/extruder-lab.com\/fr\/wp-json\/wp\/v2\/media\/105"}],"wp:attachment":[{"href":"https:\/\/extruder-lab.com\/fr\/wp-json\/wp\/v2\/media?parent=64"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/extruder-lab.com\/fr\/wp-json\/wp\/v2\/categories?post=64"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/extruder-lab.com\/fr\/wp-json\/wp\/v2\/tags?post=64"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
