The <strong>Electric Furnace for Carbon Black Testing<\/strong> manufactured by <strong>Polymer Test<\/strong>, unlike ordinary ash furnaces, is equipped with a system that allows for precise control of the atmosphere inside the furnace.<\/p>\n<h3>Operating Mechanism: Pyrolysis in Inert Atmosphere<\/h3>\n<p>To measure <strong>Carbon Black Content<\/strong>, the sample must not be burned (oxidized) but rather thermally decomposed (pyrolyzed). Therefore, this device is equipped with the following essential components:<\/p>\n<ul>\n<li><strong>Nitrogen Gas System:<\/strong> Includes connection for cylinder, regulator, and a precise flow meter to replace oxygen with nitrogen during the first phase of the test.<\/li>\n<li><strong>Quartz\/Pyrex Glassware:<\/strong> Heat-resistant tubes that contain the sample boat and direct the nitrogen gas flow over it.<\/li>\n<li><strong>Kanthal Elements (A1):<\/strong> Utilizes the best Swedish heating wires that do not deform or burn out even at temperatures up to <strong>1200\u00b0C<\/strong>.<\/li>\n<\/ul>\n<h3>Temperature Precision and Control<\/h3>\n<p>This furnace utilizes high-precision Type K thermocouples and a PID controller that displays temperature with a resolution of 1\u00b0C. Temperature stability is crucial in the <strong>Ash Content<\/strong> test to ensure the remaining weight is accurate.<\/p>\n<h3>Completing Laboratory Equipment<\/h3>\n<p>This device is typically used alongside the <a href=\"https:\/\/polymertest.com\/en\/product_en\/melt-flow-index-tester-mfi\"><strong>Melt Flow Index (MFI) Tester<\/strong><\/a> to verify raw material (granule) quality before production. The combination of Carbon Black Content and MFI results constitutes the complete &#8220;identity card&#8221; of your incoming materials.<\/p>\n<h3>International Standards<\/h3>\n<p>This device is designed and manufactured exactly according to the requirements of the following standards:<\/p>\n<ul>\n<li>Standard <a href=\"https:\/\/www.astm.org\/d1603-14.html\" target=\"_blank\" rel=\"nofollow noopener\"><strong>ASTM D1603<\/strong><\/a> (Test Method for Carbon Black Content in Olefin Plastics).<\/li>\n<li>Standard <a href=\"https:\/\/www.iso.org\/standard\/63054.html\" target=\"_blank\" rel=\"nofollow noopener\"><strong>ISO 6964<\/strong><\/a> (Determination of carbon black content in polyethylene pipes and fittings).<\/li>\n<li>Standard <a href=\"https:\/\/www.iso.org\/standard\/71205.html\" target=\"_blank\" rel=\"nofollow noopener\"><strong>ISO 3451<\/strong><\/a> (Determination of Ash).<\/li>\n<\/ul>\n<p>For price inquiries regarding the furnace and accessories, please click the contact for purchase button or visit our <a href=\"https:\/\/polymertest.com\/en\/contact-us\/\"><strong>contact us<\/strong><\/a> page.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The PolymerTest Electric Furnace is a specialized instrument designed for determining Carbon Black content and Ash content in polyolefins and rubber.
