There are 3 standards to judge the quality of aluminum spacer:
At first,to observe the surface of aluminum spacer bar. Better spacer bar with the highlight and clear
surface. If the surface was covered with oil or grease,it will be difficult to coat butyl sealant. So that
it will reduce the working life of Insulating glass.
Secondary,to observe whether air holes of aluminum spacer bar is well-distributed and well-ventilated.
If the air holes are not well-distributed and well-ventilated,it will impede the function of molecular sieve.
Finally,to check the weight.Because the thickness of spacer bar is very thin.It is very difficult to
find that whether the thickness is enough as the supplier said.Weight them (without package) is a easy
way to check it.The error of 10kg should be less than 0.1kg.
