Detailed Manufacturing Process Flow of Temperable Mirror Glass

The production of high-quality tempered mirror glass involves a meticulously controlled multi-stage process, ensuring both optical clarity and structural resilience. Our manufacturing process adheres to stringent international standards, including ISO 9001 for quality management and CE for safety glazing materials.

Phase 1: Glass Preparation & Cutting

• Material Selection: We begin with high-quality annealed float glass substrates, typically low-iron variants to ensure maximum clarity and true color reflection once mirrored. These materials are selected for their consistent thickness and absence of optical distortions.
• Precision Cutting: Using advanced CNC cutting equipment, glass sheets are cut to precise dimensions based on client specifications. This stage is critical for minimizing material waste and ensuring exact fitment for end applications.
• Edge Work & Drilling: Edges are ground and polished to remove stress points and improve safety during handling and installation. Any required holes, notches, or complex shapes are machined at this stage before tempering, as post-tempering modifications are impossible.
• Washing & Drying: The glass is thoroughly washed with de-ionized water and specialized detergents, then air-dried to remove any residue, dust, or contaminants that could affect the tempering or mirroring process.

Phase 2: Thermal Tempering

• Heating: The prepared glass is transported through a tempering furnace, where it is uniformly heated to a temperature exceeding 600°C (typically 620-680°C), just below its softening point. This process is carefully controlled to ensure consistent heat distribution across the entire glass surface.
• Quenching (Rapid Cooling): Immediately upon exiting the furnace, the glass undergoes a rapid cooling process, known as “quenching.” High-pressure air jets rapidly cool the outer surfaces of the glass, while the interior remains hot. This causes the outer surfaces to contract and solidify, creating a state of high compression. As the interior cools more slowly, it attempts to contract, but is restrained by the already solidified outer layers, resulting in a state of tension in the core. This differential cooling creates internal stresses that give tempered glass its characteristic strength.
• Testing Standards: Each batch undergoes rigorous testing to ensure compliance with relevant standards, including fragmentation tests to verify safe breakage patterns and surface compression measurements.

Phase 3: Mirroring Process (After Tempering)

• Surface Preparation: The tempered glass undergoes a secondary, even more meticulous cleaning process to ensure a pristine, molecularly clean surface for optimal adhesion of the reflective layers. This often involves chemical washes and rinsing with ultra-pure water.
• Sensitizing & Activation: The glass surface is treated with sensitizing agents (e.g., stannous chloride solution) to prepare it for silver deposition. An activating solution follows to create catalytic sites for uniform silver adhesion.
• Silver Deposition: A thin, uniform layer of silver is chemically deposited onto the glass surface. This silver layer forms the primary reflective element.
• Copper Protection: A protective layer of copper is then electroplated over the silver. This layer enhances durability, protects the silver from oxidation and corrosion, and provides a stable base for subsequent coatings.
• Protective Paint/Coating Application: Finally, one or more layers of protective paint (e.g., epoxy or phenolic resins) are applied over the copper layer. These coatings provide physical protection against scratching, abrasion, and chemical attack, ensuring the longevity and performance of the mirrored surface.

The integrated manufacturing process results in a highly durable tempered mirror glass product with an extended service life, typically exceeding 15-20 years in indoor applications, even in target industries like water supply & drainage or certain metallurgical environments where conventional mirrors would degrade rapidly. This process ensures energy saving through reduced replacement cycles and superior corrosion resistance.
