Pneumatic gun -
principle Usually a good or professional pneumatic gun for the sealant has a pressure regulator that functions on the principle of a "relief valve", which ensures that the air is supplied immediately after the trigger is pressed. Pneumatic applicator is a professional tool designed for precise application of silicones and sealants. It is used as follows:
- with a nut connects the air supply line to the exhaust pipe of the applicator;
- makes a hole in the sealant packing, and this cartridge is screwed onto the nozzle of the gun;
- the bottom is removed if the product is packaged in a tube, placed in an applicator and the valve is tightly attached;
- , when the trigger is pressed under pressure, air is supplied, which subsequently pushes the product out of the applicator.
What should not you forget when using?
If you loosen the trigger, the product will stop flowing, and the air will exit the applicator from the back, using the exhaust automatic valve. If something does not work, then most likely, you should replace the defective diaphragm of the exhaust valve.
In the air supply line that was connected to the gun, the pressure should not be more than ten bar. Do not forget to disconnect the air supply line before the applicator is dismantled.
To ensure that the tool can function without problems, it must be completely cleaned of silicone residues after use, for this use a solvent that is recommended by the manufacturer( do not immerse the gun in a solvent).
If a problem arises with the exhaust valve, it is necessary to change the diaphragm of the quick release valve as described in the instructions. Usually, the diaphragm is changed after using about two thousand cassettes. During operation, the front caps must always be fitted tightly. Wear goggles when working with any pneumatic tools.
Electric and battery pistols
The rechargeable gun for gun sealant often has a very high level of supply, works with cartridges or film bags, it can easily switch from one type of sealant to another. Most often works on lithium-ion blocks and provides high accuracy in operation, thanks to the ability to regulate the supply, and also provides cleanliness due to leakage protection. Upon completion of the work, the product does not flow from the gun, does not create unnecessary droplets, because the piston immediately returns.
Electric gun for sealant greatly simplifies the work on the filling of voids and sealing. Due to the speed controller you will be very comfortable to adjust the necessary flow of sealant in operation. For power supply, a network of alternating current with a voltage of 220 V, frequency of about 50 Hz is used.
The choice to do in favor of any of the proposed pistols is unequivocally impossible only because they all perfectly fulfill the duties assigned to them. The main difference is in the principles of power supply, which means that if the work is to be done on the site, where the power source is difficult to power, the choice falls on pneumatics and a battery pistol. If the network is available, and you will not be burdened with wires stretching to the gun, then the electric option will suit you, even if you can call it the most awkward.
When working with any kind of sealant gun, it is important to remember the safety and precautions. Use safety glasses and other protective equipment such as gloves or special work clothing. Heated or melted sealant can be dangerous, be careful.
