Detailed Manufacturing Process Flow of Blue Coated Glass

The production of blue coated glass is a sophisticated, multi-stage process that combines precision engineering with advanced material science. It begins with high-quality float glass, which serves as the substrate. The choice of substrate material is critical, often a low-iron clear float glass to ensure optimal optical transparency and color neutrality before coating.

Process Steps:

1. Substrate Preparation: High-quality float glass sheets are meticulously cleaned using a multi-stage washing process involving deionized water, specialized detergents, and high-pressure brushes. This removes all surface contaminants, ensuring pristine adhesion for subsequent layers. Surface tension analysis verifies cleanliness.
2. Coating Deposition (Magnetron Sputtering): This is the primary method for applying the desired optical and functional layers. In a vacuum chamber, the clean glass is passed beneath a series of magnetron cathodes. These cathodes contain target materials, typically metals (e.g., silver, titanium, chromium) or metal oxides (e.g., silicon dioxide, tin oxide), which are bombarded by argon ions. This bombardment dislodges atoms from the target, which then travel and deposit onto the glass surface, forming extremely thin, uniform layers (nanometer scale). For a blue tint and specific solar control properties, layers might include a combination of dielectric films and thin metallic layers designed to selectively reflect or absorb certain wavelengths of light.
3. Layer Configuration: Multiple layers are applied sequentially. A typical coating stack for blue coated glass might include:
   • Protective layer (e.g., TiO2, SiO2)
   • Functional layer (e.g., Ag for Low-E properties, or specific metal alloys for color)
   • Barrier layer (e.g., NiCr)
   • Another functional layer (for enhanced performance or specific blue coloration)
   • Top protective layer
   The precise thickness and composition of each layer are meticulously controlled to achieve the desired spectral selectivity, thermal performance, and characteristic blue hue.
4. Quality Control & Testing: Throughout the process, and post-coating, rigorous testing is conducted. This includes:
   • Optical Spectrophotometry: Measures visible light transmittance, reflectance, solar heat gain coefficient (SHGC), and U-value (thermal transmittance) to ensure compliance with specified performance parameters.
   • Adhesion Testing: Cross-hatch adhesion tests and scrub resistance tests verify coating durability.
   • Environmental Durability: Accelerated weathering tests (humidity, salt spray, UV exposure) are performed to predict service life, often adhering to ISO 9227 (Salt Spray) and ASTM C1376 (Standard Test Method for Measurement of Architectural Glass by Spectrophotometry).
   • Visual Inspection: Ensures freedom from defects such as pinholes, scratches, or uneven coating.
5. Cutting & Finishing: The coated glass is then cut to precise dimensions using CNC machining, followed by edge processing (e.g., grinding, polishing) and tempering (if required for safety glass applications) to meet specific project requirements.

Materials, Standards, and Service Life:

Typical materials used in coating include silver (Ag) for low-emissivity, titanium (Ti), silicon dioxide (SiO2), tin oxide (SnO2), and various nitrides for durability and specific optical properties.
