Why do you need and what can you use a construction hair dryer for?

What is and what does a construction hair dryer look like?

A household tool supplies hot air to a selected object. The photo of a construction hair dryer shows that in appearance it most closely resembles an electric drill or a regular hair dryer. But its operating temperatures are much higher than the latter.

A construction hair dryer consists of a housing under which a powerful motor is hidden. On the internal spindle of the device there is a fan that forces air into a thermally insulating casing with a heating element, usually ceramic with a nichrome spiral. The casing has an outlet nozzle through which a hot air stream is supplied.

Many models of construction hot air guns are equipped with a long handle on which there is a start button and mode switching keys. Because of this shape, the tool can be called a heat gun.

The handle usually has rubber pads to prevent slipping.

Depending on the model, hair dryers may vary in size and weight. On average, the length of the instrument is 22-30 cm, and the weight is up to 1 kg, in rare cases up to 2 kg.

Important! The more massive the heat gun, the higher its power. But working with heavy tools is not very convenient; your hands get tired quickly.

Operating a hair dryer

A construction hairdryer is good for removing old paint, especially from wood. A temperature of 500° C is sufficient. Warming up is carried out in small areas - the swollen paint is cleaned off with a scraper.

Using a hair dryer, wooden surfaces are given a noble dark shade. Coniferous trees are better suited - spruce, pine, etc. Operating temperature - 600 ° C, high flow rate. The distance from the nozzle to the surface is 1 cm.

Joining pipes with a technical hair dryer is distinguished by its simplicity and quality. At the joints it is necessary to cut off the edges and press the ends together. The resulting groove is filled using a plastic rod and hot air, and the remaining end of the additive is trimmed.

A hair dryer allows you to bend plastic pipes. 400° C is enough, and to prevent the pipe from bursting, a spring or sand is placed inside. The bent pipe is not released until it cools completely.

The connection of linoleum or film is made through an overlap of 2-3 cm, heated from the outside with a hairdryer with a narrow nozzle at close range. Temperature - 300° C, wiring along the joint is done quickly (depending on the thickness of the material).

This is not a complete list of the functions of a hair dryer. The unit adapts to any work requiring the supply of hot air. Therefore, the heat gun is capable of fanning coals for barbecue, heating rusted nuts (for easy removal), and drying/disinfecting products and surfaces. A convenient technical hair dryer is indispensable for repair work - the use depends on the needs and ingenuity of the master.

Working with a hair dryer requires certain safety rules:

• The new unit warms up at low speed for fifteen minutes before starting stable operation;
• Do not suddenly give high power;
• Air intake grilles must be open;
• It is necessary to take a break from work every fifteen minutes.

Conclusion

The price of a construction hair dryer with temperature control varies depending on the model, manufacturer and additional equipment.

When purchasing, you should pay attention to the presence of a warranty card and a quality certificate. It is important to correctly compare the required qualities with the actual capabilities of the thermal unit.

How does a hair dryer work?

The operating principle of a hair dryer is practically no different from the operation of a conventional hair dryer. An electric motor, using a fan, draws air inside the device through special holes, directing it to the heating element.

When passing through a hot coil, the flow reaches very high temperatures, and is then transferred to the outlet nozzle on the other side of the hair dryer. A directed hot jet bursts out of the nozzle at high speed, capable of not only heating, but also melting objects.

Types of construction hair dryers

Construction hot air guns are divided into categories rather arbitrarily. It is customary to distinguish the following types according to power:

1. household - up to 1.1 kW;
2. professional - on average up to 2 kW;
3. industrial - 2 kW or more.

The higher the power of the hair dryer, the higher its maximum temperatures. Industrial models are capable of delivering a jet of air at about 700 °C.

Another classification divides hair dryers by design.

1. Pistol. These models are the most popular; they have a handle located perpendicular to the body, on which control buttons are mounted.

   
   Pistol hair dryers are quite lightweight - they can be held with one hand.

2. Direct. These models do not have a handle; they have an elongated shape. You need to hold a straight hot air gun by the body, which allows you to conveniently grab it with both hands, but at the same time increases the risk of burns or electric shock.

   
   Straight heat gun is good for working in confined spaces

Another classification divides technical hair dryers into varieties according to the type of power supply:

1. From the network. Models are more powerful, but they can only be turned on close to an outlet.

   
   The range of a powered hot air gun is limited by the length of the cord

2. From the battery. You can use a technical hairdryer of this type anywhere, but its capabilities are limited.

   
   Cordless heat guns are very convenient, but not suitable for long-term work

The handle of pistol models can be not only open, but also closed, protecting fingers from accidental burns. In addition to the fact that such devices are safer, they can be comfortably grabbed with two hands. But at the same time, the disadvantage of the protected design is its bulkiness; you cannot use such a hairdryer in hard-to-reach places.

Video “Thermal gun and its scope of application”

A construction hair dryer has worked well in removing old paint. To clean large wooden surfaces, you need to use a wide nozzle. When performing work with the device, special clothing, glasses and gloves are required. When processing painted surfaces, the temperature regime should be set to the maximum value. The air stream should also be as powerful as possible. The material is heated in small areas. Under the influence of temperature, paint wrinkling, swelling and peeling occurs. You can use a scraper to remove it. The layer is removed together with heating of the next surface area.

This method allows you to remove old paint only on a smooth or slightly rounded surface; it is not suitable for wood.

Decades ago, a blowtorch was used to remove paint from wood materials. Today it is much more optimal to use a technical hair dryer, which is safer and more convenient.

First of all, the working surface is cleaned with a brush, the remaining paint and dust are removed with a vacuum cleaner, after which the material is processed with a hairdryer. For such types of work, a wide nozzle is used. Thanks to it, it is possible to achieve uniform heating of the treated area. The temperature during processing and the strength of the air flow should be set to the maximum.

Surface treatment is carried out in small areas with a change in the direction of the air flow. The distance from the hair dryer and the material is 1 cm or more; if you process it more closely, this is fraught with the formation of defects on the wood. To obtain a uniform pattern, processing should be carried out at a greater distance. To achieve a good result, you need to work with a hairdryer for quite a long time, but it's worth it.

What can it be used for and why do you need a construction hair dryer?

Videos about what you can do with a hair dryer present it as a universal device with a wide range of applications. The possibilities of use are practically unlimited; the device will be in demand wherever high-temperature processing is needed:

1. Using a hair dryer, you can stick vinyl film on any surface or carefully remove stickers and tinting from objects.
2. The device is used to solder and mold plastic parts, for example, when installing drainpipes. The device allows you to make and attach patches to an object. You can also remove shallow scratches from plastic surfaces without leaving a trace using heating.
3. Another area of ​​application for a construction hair dryer is electrical work. With its help, small parts are soldered and desoldered, and the chips of motherboards, video cards, and smartphones are warmed up.
4. The tool allows you to defrost brake pads or car glass; battery-powered models are especially convenient in this regard. Also, using the device, minor dents are leveled out on the car body.
5. In furniture production, using a heat gun, you can glue parts and replace decorative edges. If you heat the wood with hot air and then treat it with beeswax, you will be able to return the beautiful shine to the product.
6. A hair dryer is suitable for sterilizing metal objects. It can be used to clean manicure and pedicure tools after use.
7. The device is used to remove contaminants. A stream of hot air effectively burns away plaque from ceramic and metal surfaces.

In home repairs, a technical hair dryer is most often used to remove old paint.
An unusual option for using a construction hair dryer in everyday life is heating and cooking. At the dacha, using the device, you can make popcorn or fry shish kebab, bake meringues or make coffee if other equipment and an open source of fire are not at hand.

How to use a hair dryer

A technical hot air gun is a rather dangerous device to use. If you handle it carelessly, you can get serious burns, so it is very important to carefully follow the operating instructions and safety precautions. For any method of using a construction hair dryer, you must:

• ensure good ventilation of the room;
• remove all potentially flammable or explosive objects from the work area;
• during operation, keep the hot air gun below or above the level of the head, so as not to burn your face in case of a possible mistake;
• use safety glasses and gloves.

There are also general rules for using a hair dryer, which recommend:

• start the device into operation smoothly, from low power to maximum;
• before turning off the hair dryer, first turn it back to the minimum settings so that the temperature changes gradually;
• Before operation, check whether the air intake grilles are open, otherwise the unit will quickly overheat and fail;
• take short breaks when working for a long time; usually construction hair dryers are not designed for continuous operation longer than 20 minutes.

When working with a technical hair dryer, you should wear gloves that are as tight as possible.
Before turning on the device, you should carefully study the instructions for using the construction hair dryer and determine which mode you need to set to carry out certain work. You cannot select the temperature and blowing speed settings at random - this will reduce the efficiency of using the device, and in some cases it will damage the surface being treated.

Advice! When you turn on a new device for the first time, you need to let it run idle for 15-20 minutes.

A brand new hair dryer may emit a specific odor when starting up; it comes from burning dust and lubricant residues inside the device. Normally, the aroma quickly disappears on its own and does not indicate any damage.

How to replace a hair dryer at home

A technical hair dryer is not present in every tool cabinet. Sometimes the need for a device arises suddenly and urgently.

It is quite difficult to completely replace a specific device; for example, a regular hair dryer for repair and construction purposes is clearly not suitable. The closest thing to a device in terms of properties and capabilities is a gas burner. It only needs to be slightly improved before use.

The burner functions as follows: compressed gas is supplied from a cylinder, and when a special button is pressed, its stream is ignited by a spark. In this case, the flame power can usually be adjusted using a valve. To convert a burner into a hair dryer, you only need to equip it with a homemade nozzle that will hide the fire and leave a stream of hot air at the outlet.

You can do it like this:

• select a metal tube whose width will coincide with the inner diameter of the burner outlet nozzle;
• insert the elements tightly into each other, the structure should not play or fall out;
• If necessary, cut the nozzle slightly to length.

You can upgrade a gas burner to a hot air gun in a few minutes.
Then all that remains is to check the device in operation. Open the gas valve slightly and press the spark button. When the structure is properly assembled, the flame should not extend beyond the installed nozzle - only air is needed for heat treatment.

A homemade hot air gun will not be as convenient to use as a real one; for example, it will be more difficult to regulate the temperature and determine its current values.

But for simple urgent work, a converted burner is suitable, for example, it can be used to warm up objects and surfaces, soften glue, and remove old paintwork from a wall.

Important! When using a homemade hot air gun, you must follow standard safety precautions, wear gloves and safety glasses, and do not point the device at flammable objects.
