Fastening of parts or designs glue — one of the easiest and convenient ways of connection. In many cases use of thermogun will be optimum.
Chemists have developed huge number of types of glue for various cases. Without big exaggeration it is possible to claim that modern glue can paste anything to anything.
However all glue structures have one general bottleneck: that glue has hardened, time is required. For this reason fast-setting glues are so popular. Glue-fusion belongs just to this category.
Features of thermoglue
The principle of use of thermoglue is very simple: by means of special adaptation glue weight is warmed up to the temperature at which the structure becomes liquid, applied on surface of one of stuck together parts then parts immediately connect. After cooling, glue hardens and connection can be operated.
Advantages of thermoglue:
- universality (sticks together the majority of materials);
- possibility of the choice of optimum glue from several grades;
- speed of skhvatyvaniye;
- high strength;
- small shrinkage, ability to fill cavities.
Shortcomings:
- need to use special purpose tool for glue warming up up to the working temperature;
- the warming up requires time, it is required to turn on the heater in advance;
- difficulties when using glue on cold (fusion quickly cools down or does not heat up to the necessary temperature at all);
- difficult pasting of parts with the high thermal capacity and heat conductivity (parts need to be warmed before gluing together).
In life for work with glue-fusion the thermogun is used.
Choice of thermogun
In the body of thermogun the electric heater is placed. By means of trigger the rod from the glue weight which melts and squeezed out through nose on adherend part is gradually moved into it.
Choosing thermogun, it is important to pay attention to three parameters:
- energy source,
- device power,
- diameter of the used rods.
Energy source
The majority of models of the guns provided on sale work from the power supply network of 220 Volts. Such simple and cheap technical solution possesses obvious shortcoming: the gun will not work in places where there is no network. If the mobility is necessary for you and you do not want to depend on availability or lack of the electric socket, choose accumulator thermogun.
Power
The high power of the device, subjects more its performance and the quicker it will come to operating mode after inclusion. Big power gives the chance to prepare more glue for smaller time. It is crucial for pasting of large parts. The low-power thermogun is useless here: until you apply glue on adherend surface, the first portions will be in time will cool down and to harden.
Diameter of glue sticks
The majority of models of thermoguns are intended for work with the rods Ø of 11 mm. You can easily find spare glue sticks of different function in sale.
For delicate and delicate works the amateur master will prefer gun with smaller diameter — 7 mm.
