\u771f\u7a7a\u6d17\u6d44\u7089<\/strong>, https:\/\/8ruiyan.com\/en\/all-vacuum-cleaning-furnaces\/<\/a>as an efficient and eco-friendly cleaning solution, is increasingly becoming the industry’s preferred choice.<\/p>\n\n\n\n

In the polymer processing industry, production equipment (such as spinnerets, extruder screws, and molds) accumulates residual polymers, additives, or carbon deposits during use, affecting product quality and production efficiency. Traditional cleaning methods (such as chemical cleaning or incineration) suffer from environmental pollution, inefficiency, or potential damage to workpieces.\u00a0<\/p>\n\n\n\n

This article provides a detailed introduction to the working principle<\/strong> of vacuum cleaning furnaces, their four main types (horizontal, cabinet, vertical, and pit-style)<\/strong>, and their advantages and disadvantages<\/strong>, helping you select the most suitable cleaning solution.<\/p>\n\n\n\n

Working Principle of Vacuum Cleaning Furnaces<\/strong><\/h2>\n\n\n\n

Vacuum cleaning furnaces utilize high-temperature pyrolysis in a vacuum environment<\/strong>, breaking down polymers into small volatile molecules under oxygen-free conditions, which are then evacuated by a vacuum pump, ensuring thorough cleaning. The core principles include:<\/p>\n\n\n\n

    \n
  1. Oxygen-free environment<\/strong>: The vacuum state (typically 1~100 Pa) prevents polymer oxidation and combustion, minimizing residual ash.<\/li>\n\n\n\n
  2. Thermal cracking reaction<\/strong>: Heating to 300~500\u00b0C breaks polymer molecular chains, decomposing them into gases and minimal residues.<\/li>\n\n\n\n
  3. Volatile removal<\/strong>: The vacuum pump continuously extracts cracked gases, ensuring complete cleaning.<\/li>\n<\/ol>\n\n\n\n

    The entire process is flameless and chemical-free<\/strong>, making it environmentally friendly and non-damaging to workpiece surfaces.<\/p>\n\n\n\n

    Four Types of Vacuum Cleaning Furnaces and Their Pros & Cons<\/strong><\/h2>\n\n\n\n

    1. Horizontal Vacuum Cleaning Furnace<\/strong><\/h3>\n\n\n\n

    Features<\/strong>: The furnace body is horizontally arranged, with rail or cart loading, suitable for elongated workpieces (e.g., screws, molds).<\/p>\n\n\n\n
