It heats polymer residues (like those in spinnerets, filters, and extruder parts) to a temperature where they\u00a0<strong>crack and pyrolyze<\/strong>. The vacuum environment plays a crucial role: it\u00a0<strong>removes oxygen<\/strong>\u00a0to prevent burning and oxidation, and it\u00a0<strong>evacuates the decomposed residue<\/strong>\u00a0from the chamber\u00a0<a href=\"https:\/\/8ruiyan.com\/boiler-products\/\" target=\"_blank\" rel=\"noreferrer noopener\"><\/a>.<\/li>\n\n\n\n<li><strong>Core Advantage<\/strong>: The process is\u00a0<strong>clean and residue-free<\/strong>. By avoiding combustion, it leaves no ash and causes no oxidative damage to the expensive tooling being cleaned, significantly extending its service life.<\/li>\n\n\n\n<li><strong>Environmental &amp; Safety Benefit<\/strong>: The vacuum system captures the fume and volatile by-products of the pyrolysis process, making it a much cleaner and safer alternative to fluidized beds or salt baths.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Primary Applications<\/h3>\n\n\n\n<p>Its use is almost exclusively focused on the polymer and plastics industries:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Cleaning Spinnerets<\/strong>: Essential in the synthetic fiber industry (for materials like polyester and nylon) to remove hardened polymer from the fine holes of spinnerets.<\/li>\n\n\n\n<li><strong>Cleaning Extrusion Tools<\/strong>: Used to clean dies, screws, and filters in plastic extrusion and molding operations.<\/li>\n\n\n\n<li><strong>General Polymer Component Cleaning<\/strong>: Effective for cleaning various components contaminated with polymers.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Head-to-Head Comparison<\/h2>\n\n\n\n<p>o make the right choice, you need to see how these two furnaces stack up against each other.
