Vacuum Cleaning Furnace: The Ideal Solution for Efficient Polymer Cleaning

Tungku pembersih vakum, https://8ruiyan.com/en/all-vacuum-cleaning-furnaces/as an efficient and eco-friendly cleaning solution, is increasingly becoming the industry’s preferred choice.

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. 

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

Working Principle of Vacuum Cleaning Furnaces

Vacuum cleaning furnaces utilize high-temperature pyrolysis in a vacuum environment, 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:

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

The entire process is flameless and chemical-free, making it environmentally friendly and non-damaging to workpiece surfaces.

Four Types of Vacuum Cleaning Furnaces and Their Pros & Cons

1. Horizontal Vacuum Cleaning Furnace

Features: The furnace body is horizontally arranged, with rail or cart loading, suitable for elongated workpieces (e.g., screws, molds).

Advantages:

• Exceptional load capacity, capable of cleaning heavy components.
• Excellent thermal insulation, energy-efficient.
• Ideal for specialized industrial needs (e.g., aerospace components).

Disadvantages:

• Complex installation, requiring underground construction.
• Difficult maintenance, with higher inspection costs.

Aplikasi: Heavy machinery, large molds, and specialized industrial component cleaning.

Vacuum Cleaning Furnace vs. Traditional Cleaning Methods

Comparison	Tungku Pembersih Vakum	Chemical Cleaning	High-Temperature Incineration
Eco-Friendliness	✅ Pollution-free, minimal gas emissions	❌ Difficult chemical waste disposal	❌ Harmful smoke generation
Cleaning Effect	✅ Thorough, no residue	⚠️ Potential workpiece corrosion	❌ Ash residue
Energy Consumption	⚠️ Medium-high (electric heating)	✅ Low	❌ Very high (gas/oil)
Workpiece Damage	✅ No oxidation or deformation	❌ Possible corrosion	❌ Risk of thermal deformation

How to Choose the Right Vacuum Cleaning Furnace?

1. Based on workpiece size: Large workpieces—horizontal/pit-style; small/medium—cabinet/vertical.
2. Production volume: Batch production—horizontal; labs/small batches—cabinet.
3. Workshop space: Limited space—vertical or cabinet.
4. Budget: Pit-style is the most expensive;

Kesimpulan

Vacuum cleaning furnaces, with their efficiency, eco-friendliness, and non-damaging properties, are gradually replacing traditional cleaning methods. Horizontal, cabinet, vertical, and pit-style furnaces each have unique advantages, allowing users to select the best option based on workpiece type, production needs, and space constraints.

With advancements in smart controls and energy-saving technologies, vacuum cleaning furnaces will play an even greater role in the polymer processing industry!
