Cordierit-Filter bieten hervorragende Filtrierungsleistung. Dank der g\u00fcnstigen thermischen Eigenschaften des Werkstoffes k\u00f6nnen Filter zum Einbau in Fahrzeugen leicht zusammengestellt werden. Der gr\u00f6\u00dfte Nachteil von Cordierit ist der relativ niedrige Schmelzpunkt (etwa 1200 \u00b0C): Cordierit-Substrate k\u00f6nnen bei der Filterregeneration schmelzen. Dies ist insbesondere bei st\u00e4rkerer Beanspruchung als gew\u00f6hnlich der Fall. Abgesehen von einem Ausfall des Systems tritt dies eher bei passiven Systemen als bei aktiven Systemen auf.<br \/>\nCordierit-Filter \u00e4hneln Katalysatoren mit wechselseitig verschlossenen Kan\u00e4len: Das Abgas wird dadurch gezwungen, die por\u00f6se Wand zu durchstr\u00f6men, wodurch sich die Partikel an der Oberfl\u00e4che ansammeln.<\/p>\n                <\/div>\n\n                \n                          <\/div>\n          <\/div>\n        <\/div>\n<\/div>\n\n\n<div class=\"image-text-block container mt-125 mb-125\">\n  <div class=\"row\">\n              <div class=\"col-12 col-md-6 image-text text text-vertical-center\">\n            <div>\n              \n              \n                                  <div class=\"bg-primary mb-3\" style=\"width: 86px;height: 4px;\"><\/div>\n                \n                                  <h2 class=\"h1 mb-3\">Siliziumcarbid-Wandstromfilter<\/h2>\n                \n                <div class=\"text-muted\">\n                  <p>Beim\u00a0EHC PF\u00a0kommt Siliziumcarbid (SiC) als Werkstoff zum Einsatz. Siliziumcarbid (SiC) ist ein beliebter Filterwerkstoff, da SiC-Filter eine hervorragende Filtrierungsleistung bieten und einen hohen Schmelzpunkt von 2700 \u00b0C aufweisen. Kleine SiC-Filter werden aus Einzelteilen gefertigt, gr\u00f6\u00dfere Filter hingegen aus einzelnen Segmenten mit einem speziellen Klebemittel zusammengeklebt, sodass die W\u00e4rmeausdehnung des Dieselpartikelfilters vom Klebemittel aufgenommen wird und nicht vom Mantel. SiC-Filter sind in der Regel teurer als Cordierit-Filter. Da sich deren Fertigungsverfahren jedoch sehr \u00e4hneln, lassen sie sich h\u00e4ufig gegenseitig austauschen. Auch Siliziumcarbid-Filter \u00e4hneln Katalysatoren mit wechselseitig verschlossenen Kan\u00e4len: Das Abgas wird dadurch gezwungen, die por\u00f6se Wand zu durchstr\u00f6men, wodurch sich die Partikel an der Oberfl\u00e4che ansammeln.<br \/>\nDas Substrat des Dieselpartikelfilter-Wandstromfilters zeichnet sich durch folgende Eigenschaften aus: Partikelgr\u00f6\u00dfe 0,2-150 \u03bcm, hohe Filtrierungsleistung (bis zu 95 %), hochtemperaturbest\u00e4ndig.<\/p>\n                <\/div>\n\n                \n                          <\/div>\n          <\/div>\n                <div class=\"col-12 col-md-6 image-text image \">\n            <div>\n                              <img decoding=\"async\" alt=\"\" src=\"https:\/\/ehcteknik.com\/wp-content\/uploads\/2019\/12\/Silicon-carbide-wall-flow-filters.png\">\n              \n                          <\/div>\n          <\/div>\n        <\/div>\n<\/div>\n\n\n<div class=\"image-text-block container mt-30 mb-30\">\n  <div class=\"row\">\n              <div class=\"col-12 col-md-6 image-text image \">\n            <div>\n                              <img decoding=\"async\" alt=\"\" src=\"https:\/\/ehcteknik.com\/wp-content\/uploads\/2019\/11\/mikroglasfiber-filter.jpg\">\n              \n                          <\/div>\n          <\/div>\n                <div class=\"col-12 col-md-6 image-text text text-vertical-center\">\n            <div>\n              \n              \n                                  <div class=\"bg-primary mb-3\" style=\"width: 86px;height: 4px;\"><\/div>\n                \n                                  <h2 class=\"h1 mb-3\">Einweg-Mikroglasfaser<\/h2>\n                \n                <div class=\"text-muted\">\n                  <p>Die Filtermedien der DPF\u00a0EHC HT,\u00a0EHC L20\u00a0und\u00a0EHC P15\u00a0sind aus Mikroglasfaserwerkstoffen gefertigt.
