Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing engineered stone technologies struggle to replicate the visual depth and light transmittance of natural quartzites, particularly when using colored pigments and opaque inorganic quartz particles.
Innovation Solution
An artificial marble composition comprising a binder resin, inorganic particles with a barium element, and quartz powder, where the inorganic particles have a barium content of 10-35% by weight, and the quartz powder has a SiO2 content of 99.5-100%, to achieve high light transmittance and visual similarity to natural quartzites.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If colored pigments and opaque inorganic quartz particles are used in existing E-stone production process, then color development and pattern variety are improved, but light transmittance and visual depth are reduced
Solution Approach 1:
The patent changes the chemical composition parameters of inorganic particles by incorporating barium elements (BaO content: 10-35 wt%) alongside silica (SiO2: 65-85 wt%). This compositional parameter change transforms the particles from opaque to transparent while maintaining their function as filler and pattern-forming elements, thereby resolving the contradiction between color development and light transmittance.
Solution Approach 2:
The patent creates a composite material system combining binder resin (90-99 wt%), transparent barium-containing inorganic particles (0.1-2.5 mm, 1-50 parts by weight), and transparent quartz particles (0.1-0.5 mm, 50-99 parts by weight). This composite structure enables simultaneous achievement of color patterns, visual depth, and high light transmittance (6-20%), resolving the contradiction between aesthetic appearance and optical properties.
2Illumination intensity
If transparent inorganic particles are used to improve light transmittance, then visual depth and clarity are improved, but color development and pattern richness are reduced
Solution Approach 1:
The patent applies local quality by using transparent particles with different sizes (barium-containing particles: 0.1-2.5 mm, quartz particles: 0.1-0.5 mm) and different distributions within the binder resin. This size differentiation and spatial distribution create visual depth and pattern richness through light scattering and refraction at different levels, while maintaining overall transparency and color development.
