Foam adhesive is a kind of mainly used for filling, sealing and bonding at the edge joints of building doors and windows, expansion joints of components and holes. It is a kind of polyurethane elastic sealing foam material that relies on moisture curing. It is divided into gun type and tube type two kinds, gun type is need special polyurethane foam gun to use, tube type with disposable hose. It is a one-component, moisture-curing, multi-purpose polyurethane foam filling elastic sealing material. Foaming rubber is the polyurethane prepolymer, foaming agent, catalyst and other components filled in a pressure-resistant aerosol cans in the special polyurethane products.
Applications:
Door and window installation: caulking and sealing between door and window and wall, fixed bonding.
Advertising model: the production of models, sand table, exhibition board repair.
Acoustic muffling: voice room, broadcasting room and other decoration gap filling, can play the role of sound insulation and muffling.
Gardening landscape: flower arrangement, gardening landscape, lightweight and beautiful.
Daily maintenance: repair of hollows, gaps, wall tiles, floor tiles, flooring.
Waterproof plugging: water pipes, sewers and other loopholes in the repair, plugging.
Method of use
The use of gun-type styrofoam and steps:
①Take the foam gun, clean it with polyurethane cleaner to ensure smooth;
②Then take the styrofoam, hold the middle of the canister tightly in your hand, and shake it hard in a transverse direction along the canister for at least 15-30 seconds to make sure that the canister pre-polymers are well-mixed;
③ Remove the threaded ring of the gun-type styrofoam. Remove the protective skin cover of the valve on the threaded ring of the gun-type foaming gel, remove the cleaning agent on the foaming gun, and load the foaming agent canister to the interface of the foaming gun along the thread;
④Grip the handgrip of the foaming gun tightly, make sure that the canister is placed on the top, and the foaming gun is placed on the bottom of the canister, open the flow rate adjusting valve at the back of the foaming gun;
⑤ Aim the head of the gun at the bottom of the part or the inside of the part of the object to be filled, and gently pull the trigger, and start the construction. The trigger is pulled gently to start the construction. The flow rate can be adjusted to the proper flow rate by the flow rate adjustment valve at the back of the foam gun.
6 After spraying a can, if you want to fill, you can immediately remove the empty can, according to the method in point ③ to re-fill the foaming agent, continue construction.
⑦After the construction is completed, remove the material tank in time, replace the special cleaning agent to clean the foam gun, so as to avoid the residual material curing clogging damage to the foam gun.
The use of tube-type styrofoam and steps:
1, and the second step of the gun type.
2, and then take the disposable hose screwed clockwise;
3, make sure that the material tank is placed on top, the foam gun in the material tank underneath, aimed at the object to be filled parts of the bottom or inside, gently pull the trigger to start construction.
4, spray from the bottom up, spray volume to 80% of the required filling volume can be (tube filling volume of 2/3)
