995 structural adhesive and frame with aluminum profile bond instability what? Here's Auman Environmental Protection for you:

         1, the selection of profiles does not meet the requirements of the specification - the selection of material or viscose surface as material;

         2, do not do compatibility test, glue and profile itself is incompatible;

         3, compatibility test profile is inconsistent with the actual use of profiles;

         4, the difference between profiles is large;

         5, profile cleaning is not clean enough;

         6. The primer is not used correctly;

         7, uneven mixing;

         8, maintenance time is not enough;

         9. There is no strict quality control.

The above information is provided by 995 structural glue manufacturers!

         B component segregation, stratification, abnormal colloid solidification

         Segregation reason: Component B is mainly composed of curing agent, coupling agent, filler, etc., which is easily separated and stratified after a long time of placement or bumpy transportation. Not stirred well before use.

         Solution: Please stir well in the same direction before use.

         Glue in the process of "flower glue".

         Reasons for "flower glue" : 1. The B component pipeline of the glue machine is blocked. 2. The static mixer has not been cleaned for A long time, resulting in the solidified sealant blocking part of the path of the mixer, so that A and B components can not be fully mixed. 3. Different manufacturers have different product performance and different equipment process parameter Settings.

         Solution: 1. Clean Component B. 2. Clean the static mixer regularly. 3. Adjust the equipment process parameters to Good.

         When gluing, the pressure plate can not be pressed down or the phenomenon of gluing.

         Reasons: 1. The size of the packing bucket does not match that of the press plate of the glue machine. 2, the diameter of the sealing ring is too large or too small or the sealing ring aging loses elasticity.

         Solution: 1. Choose the packing bucket or dressing pressure plate size matching with the pressure plate of the glue machine. 2. Replace the sealing ring with a larger diameter or add some lining in the original sealing ring to increase the diameter of the sealing ring.

         Curing too fast or too slow.

         Cause: 1. The amount of component B is too large or too small. 2, glue equipment is not normal. 3, different manufacturers of sealant cross use.

         Solution :1. Components A and B should be used in the correct proportion (mass ratio A:B=11:1 ~ 14:1). 2. Clean and maintain glue equipment. 3, different manufacturers of sealant composition is not the same, curing system is not the same, can not be cross-used.

         After gluing, there is a section of curing, a section of not curing phenomenon.

         Cause: The B component pipeline of the glue machine is blocked, which causes the above phenomenon when the B component is supplied.

         Solution: 1. Clean the B component pipeline. 2, adjust the equipment process parameters to the best.
