🔥 Industrial Heat Gun and Geomembrane Sheet Insulation: A Small Heat Source with a Big Impact
In the world of geosynthetic engineering—where precision in installation and quality of waterproofing determine the longevity of a project—the
Industrial Heat Gun (Hot Air Gun) is recognized as one of the key tools used in installing and welding geomembrane sheets. This compact yet powerful device plays a critical role in ensuring complete waterproofing for landfills, water storage ponds, evaporation basins, and wastewater treatment lagoons.
⚙️ What Is an Industrial Heat Gun?
An industrial heat gun is a device that heats compressed air to high temperatures (typically between 250°C and 650°C) and expels it at high speed through a nozzle. This hot air stream is used in various processes such as paint removal, plastic forming, and—most importantly—thermal welding of polymer sheets.
In geomembrane projects, the heat gun is the primary tool for accurately bonding and sealing the sheet edges, where every millimeter of adhesion matters.
🔩 The Role of the Heat Gun in Geomembrane Welding
Geomembrane sheets are typically made of HDPE (High-Density Polyethylene) or LDPE (Low-Density Polyethylene). These materials are resistant to chemicals and UV rays, but they can only perform at their full potential when the seams between sheets are properly welded.
Thermal welding with a heat gun is performed as follows:
- Surface Preparation: First, the edges of the sheets are cleaned from dust and moisture.
- Temperature and Pressure Adjustment: Depending on the sheet thickness (usually 1.5 to 2 mm), the heat gun temperature is set between 320°C and 450°C.
- Applying Heat: Hot air is directed between the two layers, and with a pressure roller, the surfaces are pressed together with uniform pressure.
- Quality Testing: After cooling, the weld seam is checked for continuity, color, and mechanical strength (visual test or vacuum test).
🧰 Types of Industrial Heat Guns Used
In geomembrane installation workshops, two types of heating devices are commonly used:
- Handheld Industrial Heat Gun: For details, edges, corners, and hard-to-reach points.
- Automatic Welding Machine (Arian Weld): For long and straight paths, offering precise control over temperature and speed while creating double-track welds.
However, for delicate areas and final adjustments, the handheld heat gun remains indispensable.
