In various engineering projects, a wide variety of adhesives are used, each serving different purposes. In the case of aluminum alloy doors and windows, as well as the gaps with wall bodies, what kind of adhesive should be used?
I. What adhesive should be used for the gaps between aluminum alloy doors and windows and the wall?
Typically, polyurethane foam sealant is used. This type of adhesive is environmentally friendly, energy-saving, and easy to use. It is commonly used for sealing, filling gaps, fixing and adhering, as well as providing thermal insulation and soundproofing.
Currently, two common types available on the market are cartridge style and can style. However, these two types have different applications. The cartridge style requires a specialized polyurethane foam gun, while the can style is used with a disposable nozzle.
II. How to use a foam gun adhesive?
1. Start by taking out the foam gun and using a polyurethane cleaner to clean it. This ensures smooth operation during use.
2. Next, take the foam canister, hold the middle of the canister firmly in one hand, and shake it horizontally 15 to 30 times to ensure the contents are well mixed.
3. Remove the protective cap from the foam canister valve, and then detach the cleaning agent from the foam gun. Insert the body of the foam canister into the foam gun's connector, hold the gun by its handle ensuring the canister is positioned above, and then open the flow adjustment valve at the back of the foam gun.
4. Aim the gun nozzle at the area that needs to be filled, carefully squeeze the trigger, and adjust the flow using the adjustment valve at the back to the desired rate. When one canister is emptied, if further filling is required, remove the empty canister and repeat the steps to install a new foam canister for continued use.
5. Once the work is completed, remove the canister and replace it with a specialized cleaning agent to clean the foam gun to avoid residue hardening and blocking the gun.
In summary, it is evident from the above article that polyurethane foam sealant is typically used in this situation. However, it is essential to follow the correct sequence and guidelines when using foam sealant to ensure that the repair work proceeds smoothly while avoiding damage to materials or tools, thus saving both time and money. Hope this helps everyone!
