Polyurethane foam caulking agent is commonly known as foaming agent. As a commonly used industrial product, polyurethane foam caulking agent also plays an important role in the construction process. However, you still need to pay attention to the following issues during the construction process:
1. Polyurethane foam caulking agent has a certain post-effect. It does not need to fill all the gaps. It depends on the situation, usually half The amount is enough.
2. When it is necessary to fill a closed space, it should be ensured that there is more moisture in the cavity, and the construction needs to be carried out in batches;
3. When using polyurethane foam When applying caulking agent, it is best to use it one jar at a time. If you find that there are other materials in the jar after the construction, you can leave the foaming gun in the jar, turn off the flow regulating valve, and place it in a cool place. , use it the next day;
4. If the polyurethane foam caulking agent accidentally splashes on the clothes during the construction process, you can scrape it clean and then clean it with detergent; if it splashes on the skin, you need to use Wipe dry with a cloth and then wash with soap;
5. Smoking is prohibited when construction workers are working. Polyurethane foam caulking agents are not allowed to be near open flames, and empty cans are not allowed to be burned or burned on the spot. It cannot be punctured and children cannot play with it;
Having said so much, how should polyurethane foam caulking be used in construction?
First of all, get a foam gun. Clean well with cleaning agent to ensure that the foam gun is unobstructed; then pour the polyurethane foam caulking agent into the tank and shake it vigorously to ensure that the polyurethane foam caulking agent and prepolymer in the tank are fully mixed;
Remove the valve protective leather cover on the threaded ring of the polyurethane foam caulking agent, remove the cleaning agent, and install the polyurethane foam caulking agent can body onto the interface of the foaming gun along the threads;
Hold the foaming gun, place the can on top, put the foaming gun under the can, and open the flow regulating valve;
After the construction is completed, remove the material tank and replace it with a special Use the cleaning agent to clean the foaming gun;
The above is how to use the gun-type product. The use of the tube-type product is very simple. There is no need to use a foaming gun. You only need to remove the tube from the tank once. It is very convenient and quick to use.
