PVC welding technology using industrial hair dryers.

The Mixt company presents on the market the unique technology and equipment (industrial hair dryers) of the Leister company for PVC welding. The complex configuration of PVC products to be welded (swimming pools, attractions, car bodies, tents, shelters, etc.), thick materials (thick PVC fabric), different melting temperatures of PVC require a careful approach to the selection and configuration of hair dryers for PVC welding. What do hair dryers provide for welding PVC
: this is welding using special industrial hot air dryers using special nozzles or welding using special automatic welding machines. The melting temperature of PVC is smoothly regulated on the equipment and you can set the exact temperature. We recommend starting the welding process with a test on similar materials (scraps) to select the temperature conditions.

The main device that Russian buyers choose is the Leister Triac S hair dryer. This is a reliable and proven hair dryer for PVC welding. But we believe that in the case of “heavy” PVC welding, where it is necessary to weld heavy fabric, it is better to use a Leister Electron ST hair dryer:

The most powerful (3400W), compact and durable device from the Leister line of hand-held hair dryers, suitable for performing various tasks where increased power is required. Its power is 2 times more than the popular Leister Triac S hair dryer model, but the price is almost the same!!

Features of the Leister Electron ST hand dryer:

Here are some features of a PVC welding gun:

• high air consumption at higher power (compared to other models)
• designed for long-term operation and non-stop operation
• brushes and heating elements can be replaced multiple times
• can be installed in technological equipment
• can be used for manual work
• many different attachments that allow you to use the hair dryer in various areas

Application of a hair dryer for welding PVC:

• thermal laying of floor coverings
• thermal laying of waterproofing in construction
• thermal laying of geomembranes (landfills, waste storage facilities, etc.)
• heat shrinkage of linoleum
• Application of plastic sealants;
• removal of old coatings by construction dryers
• heating pipes in winter;
• melting various bitumens
• hot air welding of pipes
• heating construction adhesive
• heating the adhesive layer before separation
• heating the epoxy resin to cure.
• placing thermal insulation on wires;
• and much more

There are several options of different power and voltage consumption, but the main and most popular model in Russia is Leister Electron ST- 3400 W.

Application options for PVC welding equipment

For high-quality PVC welding, you need a set of equipment and attachments. Below we will talk a little about the equipment necessary for welding.

Functions

A technical hair dryer can be used to perform various tasks, including:

• welding (soldering) of plastic and polymers. This can be PVC film, awning fabrics, polypropylene, polyethylene;
• laying floor and roof coverings. A soldering gun is ideal for this task. Geomembrane and insulation can be used as roofing materials;
• heat shrink;
• heat treatment;

Step-by-step instruction

• Select a rod that matches the composition of the material. If this is not observed, then heating will occur at different times and the seam will be of poor quality.
• Select temperature mode.
• You need to clean the edges of the elements with sandpaper, a sanding machine or a file.
• Bring the rod of a welding gun with a sharp end to the finished cleaned part and begin to connect.
• While melting the rod, carefully push through the polypropylene by pressing on it. At the same time, smoothly move the solder, drowning the rod in the crack. This should be done throughout the entire seam.
• Residual particles of the rod must be removed. Use a heat gun to heat the excess and gently pull it to your side until it comes off the surface. Do this carefully as you risk tearing off the still hot part of the polypropylene.
• Once the joint has cooled completely, you can begin sanding it.

Adjusting the temperature in the Leister Electron ST hair dryer

The Leister Electron ST industrial hair dryer can be adjusted to different power levels for different attachments to achieve the required temperatures. Temperature conditions for different nozzles are presented directly on the body of the hair dryer in the form of a graph:

Temperature adjustment is carried out using a special regulator:

Features of work

To operate a hot air gun, you must have special components available: attachments, nozzles and tips. There are a variety of attachments, and the necessary ones are not always included in the kit.

Most often you have to order additional ones. Next, we list the most famous and necessary welding attachments for a construction hair dryer:

• Round (for sealing cracks, repairs).
• Flat (to remove paint, wallpaper, fixing polymer products).
• Mirror for welding (for butt method).
• Welding nozzle for a hair dryer (for connecting welding cables).
• Glass-protective (for working with glass surfaces).
• Slotted (for PVC fabric/membrane (like a semi-trailer awning)).
• Reducer attachment (point soldering).
• Carved (to cut foam).

Compounds of polymer materials are divided into three types according to the level of heating:

• Must be viscous or fluid;
• No heating required;
• Light level of heating, but without bringing the material to a viscous-fluid state.

Many articles mention different types of polymers: polypropylene, propylene, polyethylene, pvc. They almost always mean the same material because they all have the same chemical structure.

Welding rules

Many plastic products are joined by heating to a soft state. The following types of connections are distinguished, depending on the heat sources:

• High frequency alternating current
• Additive material
• Infrared or laser radiation
• Friction force
• Ultrasound

Why are Leister PVC welding machines so expensive?

Indeed, Leister tools and equipment are much more expensive than the manufacturers' analogues. But believe me, Leister quality is worth it! All equipment is made from high quality materials and thoroughly tested at the manufacturer. Welding machines and hair dryers from other manufacturers cannot work an 8-hour shift without changing their characteristics. Most of the industrial hair dryers offered on the market will begin to reduce the temperature of the air flow within a few minutes after starting work, because... It's just that the electronics are already overheated. And this in turn leads to poor-quality work results. Therefore, Leister industrial hair dryers and attachments are chosen by professionals who want to get a high-quality welding gun that will work for many years and will never let them down.

What other models of welding guns are on sale?

You can view the full catalog of industrial hair dryers in the online store (and also find out the cost): catalog of industrial hair dryers.

Hair dryer device

All professional technical hair dryers have identical operating principles and design. They are capable of heating air to temperatures above 600 degrees Celsius, which will be quite enough to perform the above tasks. For this purpose, special heating elements are used, which consist of a metal spiral and a ceramic tube. Hot air enters the nozzle under the influence of a fan located at the rear of the power tool. It is powered by a conventional electric motor.

All such devices differ in their characteristics. First of all, this concerns the volume of hot air that comes out of the nozzle per minute. In a modern soldering gun, this figure can be about 200 - 700 liters. Everything directly depends on the power of the motor.

What parameters to consider when choosing such a power tool?

Today, the best place to buy a technical hair dryer is in our online store. It is worth considering the characteristics of such a device, because the price will directly depend on this. Each buyer should pay special attention to the following parameters:

• temperature and volume of blown air. Professional hair dryers can heat air up to 650 - 700 degrees Celsius while its productivity is up to 700 liters per minute. For domestic use, a model that can heat the air to 300 - 400 degrees will be quite sufficient;
• possibility of adjusting the flow rate and temperature of the blown air. Most modern models have such functions. On professional soldering guns, there is a smooth adjustment of these indicators, which significantly simplifies a person’s work when performing specific tasks;
• the ability to maintain stable air temperature. This is possible thanks to the use of an electronic stabilization system. It can be found on most models;
• protection of internal elements from possible overheating;
• presence of a thermal protective casing. This element will protect against burns during operation. Also, soldering guns often have a removable casing, which makes it possible to work in hard-to-reach places;
• the presence of a handle, which greatly simplifies the process of using the tool.

For a technical hair dryer, the price depends on the above parameters. When choosing, it is better to consult with specialists, which will allow you to choose the most optimal option among the presented models.

Also, before making a purchase, it is better to read technical reviews about the selected hair dryer, which will allow you to be aware of how it performs in operation.
