Types of guns according to the method of supplying material
Depending on the area in which the sealant will be used, as well as the volume of work performed, the following types of guns are distinguished: mechanical( or manual), pneumatic and battery.
- The mechanical gun is often used for home repairs and professional construction( when small jobs are required).Inside is placed acrylic or silicone sealant. Extrusion is carried out by hand, by pressing the special stem. From the cylinder or cartridge begins to leave the material. In the proper proportions, they are filled with voids or isolate joints and other compounds.
- Pneumatic gun for sealant is used in small and medium construction for fixing, insulation and filling all kinds of voids. Inside is placed polyurethane or acrylic composition. Extrusion occurs automatically when the handle is released. This is due to air pressure.
-
rechargeable gun for sealant application is used for professional work with medium and large construction. It works with the help of a battery due to autonomous energy. Material is squeezed out by lowering the handle.
gun for silicone sealant ( first and second type) is often used, because silicone is suitable for joining various surfaces of glass, metal, plastic, ceramics, tiles, concrete, bricks and others.
This material is weatherproof, has excellent adhesion and is easy to use.
Types of guns according to the features of the
device. Depending on the device of the device, there are: tubular, semi-body and skeletal gun for hermetic. They all have different structures.
- The tubular or closed sealant gun has a cylinder and a stem. The cylinder functions as a cartridge, which can contain from 500 to 1600 ml of acrylic or silicone mixture. Its main advantage is that there is no need for frequent refilling of the cartridge.
- Semiuthorized construction sealant gun has a standard 310 ml cartridge. Equipped with a rod, a stand for the cartridge. The mechanism of operation of the apparatus is quite simple, since it provides a free stroke of the rod( this is its main advantage).
- . The skeleton gun has a stem and three stiffeners. The standard volume of the cartridge is 310 ml. The main advantage of this device is that you can use the mixture in parts( in small quantities).
Sealant gun: how to use
Often the question arises - and how to use a gun for sealant? For this we describe a brief and simple instruction. To begin with, install a cartridge( with a certain mixture).The rear lever is pressed to the handle, then the metal pin is pulled out. In the liberated space and place the cartridge.
Next, the piston is pressed against the stop in the newly inserted cartridge. After all these procedures, the sealant sealant gun is ready for use. By the way, it's also easy to apply. To do this, just pull the trigger( or, more simply, the lever).After finishing the installation work, the gun must be thoroughly rinsed.
