During the tempering process, we take a variety of measures to ensure the integrity of the tempered glass. Here are some of the steps we follow:
First, we adjust the thickness of the glass based on multi-point measurements. This is important because the glass needs to adhere to a precise thickness range. Any deviation from this behavior will result in inconsistent tempering.
We also visually inspect the glass surface to test for defects such as scratches, chips or stains. Only glass with suitable surface is selected for tempering.
To maintain the clarity of tempered glass, we check its optical distortion. We will be on the lookout for any wavy or uneven patterns that may impede visibility.
Throughout the tempering process, heating and cooling methods are carefully monitored. This ensures that the glass is exposed to optimal temperatures and lengths of time. Proper temperature control is critical to achieving uniform tempering.
We use specialized techniques such as polarizers or pressure inspection systems to study the pressure distribution on tempered glass. This helps us ensure that the stress distribution is even, which indicates stable tempering.
To understand the strength of tempered glass, we conducted fragility tests. This allows us to determine its resistance to the effect and guarantees that when broken, it will break down into small and harmless pieces.
There are also many chemical tests we can perform in order to study the chemical properties of glass. These checks help us compare its composition and surface resistance to ensure it meets the required standards.
To ensure the overall top-notch quality and safety of tempered glass, we test it according to industry standards set by organizations such as ASTM, EN, or ISO. This guarantees that the glass meets specific standards of satisfaction and protection.
Regular calibration and protection of our equipment, as well as laboratory testing and inspections, are performed to maintain the consistency of tempered glass throughout the manufacturing system.
