The foam gun is a special tool that allows you to carry out installation work with great convenience. In particular, he is able to accurately dose the protective solution, filling it with very hard-to-reach places. Today, many different models of foam pistols are produced. Their design is quite simple.
The foam gun is a tube with valves at the ends. To make it more convenient to work, the rod is equipped with a special handle and an exhaust valve mechanism actuated by a trigger. When choosing a gun, the following criteria must be considered. First, all parts of the tool must be made of metal. Serious companies can also make some elements from plastic, but in this case it is better to purchase only branded devices. If the foam gun is made by an unknown company, and even has a lot of plastic parts in its design, then thisIt is better not to buy the product at all. The choice of such tools is quite wide: products of the Workman and Zubr brands have proven themselves well. These devices, despite their low cost (about 500 rubles), are capable of spraying several hundred cylinders.
It's good if the foam gun has a removable design. In this case, it can be disassembled into parts, washed or replaced with a broken or worn assembly. Particular attention must be paid to the quality of the valves in the fixture. However, they can only be checked during operation. Do it in the following way. They take a can of acetone and screw it onto the gun. After a few pulls of the trigger (to fill the gun tube with acetone), the balloon is removed, and the device is left inactive for several days. After that, when pressed, acetone should escape from the exhaust valve, which has been under pressure all this time. will not be executed, and it must be taken back to the seller for an exchange. It will be inconvenient to work with such a device, it will have to be
rinse all the time, even after short breaks. Therefore, when buying a device, you must keep the cash receipt.
This tool requires proper maintenance and operation. Before starting work, it is recommended to spray the place of application of the substance with water, since for its hardeningmoisture is needed. When using foam, the coefficient of expansion must be taken into account. Therefore, the cavity must be filled by a quarter. Parts that can move when the foam expands should be fixed. The foam gun has another good feature: the wound balloon can remain on the device for quite a long time. At the same time, he is ready to work at any moment. However, do not leave an empty can on the gun. It is better to remove it, and blow the device. If the right substance is not at hand, then you can rinse the foam gun with pouring acetone, after disassembling the device.
