id=\"The_production_process\"><\/span>Het productieproces<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"Material_selection\"><\/span>Materiaalkeuze:<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Het materiaal voor het maken van grafietkroezen moet zeer zuiver, hoogkristallijn natuurlijk grafiet of kunstmatig grafiet zijn. Het koolstofgehalte van grafiet moet hoger zijn dan 99% en het gehalte aan onzuiverheden moet lager zijn dan 0,2% om de kwaliteit en prestaties van het product te garanderen.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Physical_sintering\"><\/span>Fysiek sinteren:<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>De grafietkroes wordt gemaakt door een fysisch sinterproces. Eerst wordt het grafietpoeder gezeefd om onzuiverheden en grafiet met ongelijke deeltjes te verwijderen. Dan de <a href=\"https:\/\/jinsuncarbon.com\/nl\/what-are-the-properties-of-graphite-powder\/\">grafietpoeder<\/a> wordt in de vorm van een smeltkroes geperst en bij hoge temperatuur gesinterd tot een vaste grafietstructuur.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Precision_machining\"><\/span>Precisiebewerking:<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>De gesinterde grafietkroes wordt met precisie bewerkt. Inclusief afwerking van het uiterlijk, groottecorrectie, oppervlaktebehandeling en andere processen. Door machinale bewerking en polijsten heeft hij een glad uiterlijk, precieze afmetingen en is hij gemakkelijk toe te passen en te bedienen.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Inspection_and_quality_control\"><\/span>Inspectie en kwaliteitscontrole:<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Inclusief inspectie van de materiaalsamenstelling, inspectie van de sinteruniformiteit, inspectie van de maatnauwkeurigheid, enz. Tegelijkertijd zijn ook chemische stabiliteitstests en weerstandstests bij hoge temperaturen vereist om de stabiliteit en betrouwbaarheid van het product in reacties bij hoge temperaturen te garanderen.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Sintering_process_control\"><\/span>Controle sinterproces:<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>We moeten de sintertemperatuur en sintertijd regelen om ervoor te zorgen dat de kristalstructuur van het grafietmateriaal goed wordt veranderd en een harde structuur vormt. Tegelijkertijd moet tijdens het sinterproces ook aandacht worden besteed aan het voorkomen van vervorming en barsten van de grafietkroes en moeten passende maatregelen worden genomen om de productkwaliteit te waarborgen.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Graphitization\"><\/span>Grafitisatie:<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>De smeltkroes wordt onder hoge temperatuur en zuurstofvrije omstandigheden onder stroom gezet voor een grafitisatiebehandeling om het om te zetten in een stabiele grafietstructuur.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Surface_treatment\"><\/span>Oppervlaktebehandeling:<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Dit is om de corrosieweerstand en chemische stabiliteit te verbeteren. Veelgebruikte methoden voor oppervlaktebehandeling zijn impregneren en coaten. Bij impregneren wordt de grafietkroes ondergedompeld in een specifieke vloeistof om een beschermende laag te vormen. <a href=\"https:\/\/www.xometry.com\/resources\/casting\/what-is-casting\/\" target=\"_blank\" rel=\"noopener\">coating<\/a> op het oppervlak; de coatingmethode bestaat erin het coatingmateriaal op het oppervlak aan te brengen om een beschermende laag te vormen.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Packaging_and_storage\"><\/span>Verpakking en opslag:<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Na voltooiing moet het verpakt en opgeslagen worden om productschade en besmetting te voorkomen. Veelgebruikte verpakkingsmethoden zijn plastic folie, schuimbescherming, enz. Vermijd tijdens de opslag contact met vocht en chemicali\u00ebn, houd het droog en schoon.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Technical_requirements_of_graphite_crucible\"><\/span>Technische vereisten van grafietkroezen<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>De werktemperatuur van de grafietkroes ligt over het algemeen boven de 1000\u2103 en het maximum ligt boven de 3000\u2103. De baktemperatuur is een van de belangrijkste factoren die de kwaliteit be\u00efnvloeden. Hoe hoger de baktemperatuur, hoe groter de dichtheid, hoe hoger de sterkte en hoe sterker de corrosiebestendigheid. Maar het heeft ook een grotere invloed op de prijs.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Conclusion\"><\/span>Conclusie:<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Het productieproces en de technische vereisten van grafietkroezen omvatten materiaalselectie, fysisch sinteren, precisiebewerking, testen en kwaliteitscontrole, sinterprocescontrole, oppervlaktebehandeling, verpakking en opslag. Dus alleen door een strikte controle van de kwaliteit en procescondities van elke schakel kunnen we grafietkroezen produceren met superieure prestaties en een stabiele kwaliteit.<\/p>","protected":false},"excerpt":{"rendered":"<p>Graphite crucible is a melting container for high-temperature reactions.
