Transparent Pattern Print Steel Plate UV Curing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for manufacturing steel plates with patterns are complex and costly, and they often result in low hardness and poor processability due to the use of acid etching or solutions with matting agents, which can lead to increased operating costs and reduced resolution.
Innovation Solution
A method involving the formation of a printed paint film layer on steel plates using transparent ink, cured with ultraviolet light, and dried at room temperature to achieve a high-gloss and high-hardness finish, with optional plasma preprocessing to enhance adhesion, using inkjet or laser printing at rates between 1 kHz to 20 kHz.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If acid etching is used to create patterns on steel plates, then pattern designs can be applied, but the process becomes complicated and operating costs increase
Solution Approach 1:
The invention extracts and eliminates the acid etching step from the manufacturing process. Instead of using acid etching to create patterns, the patent applies transparent ink directly to the steel plate surface, which is then cured to form the desired pattern. This removes the complex multi-step process of acid etching, washing, and polymer removal, simplifying the overall manufacturing process while maintaining pattern application capability.
Solution Approach 2:
The invention replaces the chemical acid etching system with a physical curing system. Instead of using acid to dissolve and create patterns, the patent uses ultraviolet light curing to harden transparent ink on the steel plate surface. This substitution eliminates the need for acid handling, neutralization, and extensive washing steps, significantly simplifying the manufacturing process.
2Ease of manufacture
If silica particles are added to solution to create etching effect, then gloss is lowered, but hardness of paint film increases and processability deteriorates
Solution Approach 1:
The invention extracts and removes silica particles and other matting agents from the ink formulation. Instead of relying on these particles to create the etching effect and reduce gloss, the patent uses pure transparent ink that is cured to achieve the desired appearance. This eliminates the problems of increased hardness and poor processability associated with silica particle addition.
Solution Approach 2:
The invention changes the fundamental parameter of how the etching effect is achieved - from particle-based matting to light-based curing. By using ultraviolet light to cure transparent ink, the patent achieves the desired gloss reduction and pattern effect without introducing particles that would harm paint film hardness and processability. The curing process allows precise control over the etching effect through parameter adjustment.
3Ease of manufacture
If excessive silica is added to solution, then etching feeling is enhanced, but resolution is lowered
Solution Approach 1:
The invention replaces the particle-based matting system with a light-based curing system. By using ultraviolet light to cure transparent ink, the patent achieves high-resolution patterns without the resolution-degrading effects of excessive silica particles. The optical curing mechanism allows for precise pattern definition while maintaining the desired etching feeling through controlled gloss reduction.
