995 neutral silicone glue due to improper glue selection or improper operation, there will be some problems in the process of use, in order to avoid the occurrence of these problems, Auman environmental protection Xiaobian is now the causes of the problem and solutions summarized as follows:

         First, there are bubbles in the colloid

         Causes of bubbles:

         1. When replacing the rubber bucket, the air mixed with the bucket and the rubber surface is not discharged cleanly.

         2. Improper use of bottom glue in the collection bucket.

         3. When the sealant is used up and needs to be changed, it is not replaced in time. The rubber supply pump has been running empty, so that the air is mixed with the rubber supply cylinder. Air and sealant mix, produce or large or small bubbles.

         4, cleaning glue equipment solvent is not volatilized completely, glue attached to the surface of the sealant, sealant and substrate bonding surface formed pores.

         Solution:

         1. After cleaning the gluing equipment, arrange more glue, and carry out normal construction after the complete volatilization of the solvent.

         2. It is recommended to replace sealant in time after it is used up, and avoid idling glue pump.

         3. Open the exhaust valve after changing the barrel, so that all the gas in the pressure disc is discharged, and a small amount of glue spills out from the exhaust port, and there is no sound of firing.

         Two, the bond is not stable

         Cause: When part of the path of gluing equipment is blocked or the air pressure is unstable, it will cause abnormal gluing equipment, and the ratio of A and B is unstable. When the fluctuation is large or even exceeds the normal proportion range, it will cause abnormal sealant curing, unstable bond or prolonged bond time.

         Solution:

         1, in the construction process, often check the air source, the stability of the perfect air pressure, and regularly clean the glue equipment, so that the glue path is smooth.

         2, OM906 silicone hollow sealant A, B component of the use of mass ratio range of 11:1 ~ 14:1,. It is better to use a mass ratio of 12:1, which is converted into a volume ratio of about 8.5:1.
