The manufacturing secret of transparent colored acrylic sheet: How to balance color saturation and light transmittance?
In today's architectural decoration, advertising signs and art design fields, transparent colored acrylic sheets are highly favored for their unique visual effects and functionality. As China's leading manufacturer of cast acrylic sheets, Hangzhou Oleg International Trade Co., Ltd., with ten years of professional experience, will reveal to you the manufacturing process of high-quality transparent colored acrylic sheets.
1. Raw material selection: the cornerstone of quality
We use high-purity MMA monomer imported from Germany as the basic raw material, and its light transmittance can reach more than 93%. In order to ensure the true reproduction of color, we select products from internationally renowned color paste suppliers, which have:
Excellent dispersion stability
Excellent weather resistance
Accurate color reproduction
In the 50,000 square meter production base in Huzhou, our 6 fully automatic production lines are equipped with precision metering systems to ensure the consistency of the raw material ratio of each batch.
2. Precision casting process: the art of balance
The key to balancing color saturation and transmittance lies in our patented casting process:
1) Prepolymerization stage:
Strictly control the temperature at 45-50℃
Use low-speed stirring to ensure uniform dispersion of color paste
Vacuum degassing to eliminate impurities
2) Polymerization stage:
Gradient heating technology (50℃→80℃→120℃)
Constant temperature control accuracy ±0.5℃
Polymerization time accurate to hours
This process makes our products not only bright and full in color, but also maintain a transmittance of more than 92%, far exceeding the requirements of GB/T7134-2008 standard.
3. Color management system
To ensure color consistency, we have established a complete color management system:
Use spectrophotometer for color detection
Establish a dedicated color database
Achieve color deviation control of ΔE≤1.5
Support Pantone color card customization
Our 370-person professional team can provide customers with a full range of color solutions from design to production, with an annual production capacity of 35,000 tons to meet various batch requirements.
4. Quality Assurance System
Each piece of OLEG transparent colored acrylic sheet is strictly tested:
Transmittance test (in accordance with ASTM D1003 standard)
Color difference test (using X-Rite spectrophotometer)
Weather resistance test (QUV accelerated aging test)
Mechanical property test (impact resistance, bending strength, etc.)
5. Application solutions
