Use of glue during rubber and plastic construction

During the construction of rubber foam insulation for pipes, air-conditioning pipes, and so on, glue needs to be used for bonding and fixing. The following describes the use and precautions of glue.

① Before using the glue, shake it gently to make the glue mix evenly. In actual use, use a small pot of glue to prevent the glue from volatilizing too quickly. Of course, you can also pour the glue from the big can into the small can. The mouth of the can must be sealed when not in use to prevent the glue from evaporating.

② When the glue is not used, the brush cannot be immersed in glue.

③ Apply glue evenly on the surface of the material to be bonded and wait for the glue to dry to the extent that it does not stick to hands. At this time, the best bonding effect is achieved. The natural drying time of the glue is about 3-8 minutes, and the specific time depends on the temperature and relative humidity of the construction environment.

④ If the glue is completely dry, reapply the glue. If the glue dries more than twice, the old glue must be removed before applying the refreshed glue layer.

⑤ The amount of glue: each liter of glue can be painted 3 to 4 square meters of sheet or 15 to 18 meters of pipe.

⑥ The temperature range of glue is 5 ℃ -70 ℃.
