(1) Water quality requirements for glass cleaning: Calcium and magnesium ions dissolved in water can easily remain on the glass, affecting the appearance and corroding the coating surface. Therefore, it is recommended to use softened water or pure water with a conductivity lower than 30 Siemens to clean the glass;
(2) After the glass cleaning is completed and the working section before lamination is completed, it is recommended to build a clean room to prevent dust from falling on the surface of the glass that has just been cleaned;
(3) Butyl sealant is the first seal in the production process of insulating glass and plays a bonding role between glass and aluminum spacers. Butyl sealant is required to be applied evenly without breakage in order to achieve good sealing and adhesion effect;
(4) The installation of aluminum spacers requires skillful techniques, and the margins should be placed evenly and neatly to prevent the outer channel sealant from being of different shades, which is not beautiful and prone to air leakage;
(5) Precautions for filling molecular sieves. The first is the ambient humidity, and the second is the validity period of the molecular sieve. After unpacking, use it as soon as possible. Do not expose it to the air for a long time, otherwise it will affect the ability of the molecular sieve to absorb water vapor;
