The glue gun is widely used for construction and household purposes. With its help, it is possible to easily and efficiently glue various objects together. Many would be interested to understand the characteristics of this device and to understand what type of adhesive gun to choose?
The principle of the gun under the adhesive
The principle of the pistol is as follows:
- It is loaded with special adhesive cartridges. The device is connected to the mains and the cartridges are heated to a temperature exceeding 100 ° C and melting them.
- To squeeze out the glue on the surface of the parts that need to be glued, press the trigger of the gun. At the same time, the consumption of glue is very economical due to the fact that extrusion is produced in the required quantity.
Advantages of the gun under the adhesive
The glue gun has a number of advantages, which include:
- rapid cooling. Within 10 minutes you will be able to use objects that have been glued together;
- possibility of gluing any objects.
What can I glue with a hot glue gun?
A glue gun can be used to glue virtually any parts. It is suitable for items consisting of the following materials:
- wood;
- plastic ;
- rubber;
- glass;
- metals;
- fabrics ;
- polystyrene foam;
- ceramics;
- paper;
- cardboard.
Exceptions are concrete, plaster, certain types of plastic and textiles.
What is the glue in the glue gun?
Adhesive rods can be designed for gluing various types of materials or have a universal purpose.
They differ in different parameters:
- diameter;
- length;
- color;
- temperature.
By diameter, you can distinguish the two most common types of glue rods: with a size of 7 and 11 mm. If you need to glue a small amount of parts, you will need a hot-melt glue with a diameter of 7 mm. In the case of repair work, you should use a rod with a size of 11 mm.
The length of the rods is generally from 4 to 20 cm.
Depending on the color, the glue rods are:
- white transparent - they are universal and suitable for gluing any objects;
- color opaque - also refer to universal, they are selected for joining details of a certain color;
- white opaque - designed to work with glass or metal;
- yellow transparent - glue wood, paper and cardboard;
- black or gray - they are used as a sealant and insulating material.
It should be noted that there is no uniform color differentiation, therefore, it is necessary to carefully study the instruction in which the purpose of the glue rod is indicated.
The heaters melt at a certain temperature, which can range from 100 to 200 ° C.
Kinds of pistols for glue
Pistols differ depending on their design and characteristics. For example, the following models of devices are encountered:
- Pistols with a hammer "carousel type", where the supply of glue is carried out by turning the trigger around its axis. Then the rod enters the metal chamber where it melts. The heating of the chamber takes place by means of a heating element located in its lower part. Molten glue is squeezed out of the nozzle in the required amount.
- Pistols with a trigger "slider type." In them the movement of the trigger is parallel to the trunk.
- Pistols with the ability to heat the glue rods to different temperatures using a special switch. This will allow the device to be used simultaneously as a gun for hot and low-temperature glue.
- Mini-gun, which has a thin long nozzle. It is ideal for children, as it is small in size and requires minimal effort to push.
- A pistol with its own power switch. This provides additional convenience in working with it.
Thus, you can select for yourself a gun for the glue with the most suitable characteristics.
