Use method and steps of gun type styrofoam
① Take the foaming gun and clean it with polyurethane cleaner to ensure smooth flow;
② Then take the styrofoam, hold the middle of the can body tightly with your hand, shake it at least 15-30 times along the horizontal direction of the can body, and ensure that the prepolymer in the tank is fully mixed;
③ Remove the protective cover of the valve on the gun type styrofoam thread ring, remove the cleaning agent on the foaming gun, and install the foaming agent tank onto the interface of the foaming gun along the thread;
④ Hold the handle of the foaming gun tightly to ensure that the material tank is placed above and the foaming gun is under the material tank. Open the flow regulating valve at the back of the foaming gun;
⑤ Align the gun head with the bottom or inside of the part to be filled, gently pull the trigger to start construction. The proper flow can be adjusted through the flow regulating valve behind the foaming gun.
⑥ After one tank is sprayed, if it needs to be filled, the empty tank can be immediately removed, and the foaming agent can be reinstalled according to the method in point ③ to continue the construction.
⑦ After the construction is completed, the material tank shall be removed in time, and the foam gun shall be cleaned with a special cleaning agent to prevent the residual materials from solidifying and blocking to damage the foam gun.
Use method and steps of tubular foam adhesive
1. Same as the second step of gun style.
2. Take the disposable rubber hose and screw it on clockwise,;
3. Make sure the charging tank is placed above and the foaming gun is under the charging tank. Align it with the bottom or inside of the part to be filled. Gently pull the trigger to start the construction.
4. Spray from bottom to top, and the injection amount can reach 80% of the required filling volume (the filling volume of tubular type is 2/3)
Use tips
Pay attention to the traveling speed when spraying. Generally, the spraying amount can reach 2/3 of the required filling volume. The vertical gap shall be filled from bottom to top; When filling gaps, such as those on the ceiling, the uncured foam may fall due to gravity. It is recommended that proper support be provided just after filling, and the support should be removed after the foam is solidified and bonded with the seam wall. After about 10 minutes, the foam will be debonded and cut after 60 minutes. Cut off the excess foam with a knife, and then apply cement mortar, paint or silica gel on the surface.
