Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The shipping of high solids aqueous titanium dioxide slurries is inefficient due to resource waste from transporting large amounts of water, and lower solids slurries require costly and time-consuming drying to remove excess water, and existing methods do not adequately address the dispersion of titanium dioxide particles in paints and coatings, particularly in the form of paints and coatings.
Innovation Solution
A concentrated titanium dioxide slurry composition is developed, comprising titanium dioxide particles, a dispersant package, and a dispersant package deposited on the surfaces of the titanium dioxide particles, a dispersant package, and a dispersant package, and a dispersant package, and a dispersant package, including water, preservatives, organic alkali salts, thickeners, defoamers, and resins, which enhances dispersion and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If high solids aqueous titanium dioxide slurries are shipped, then pigment concentration is improved, but water transport efficiency deteriorates due to transporting large amounts of water
Solution Approach 1:
The patent changes the physical state of the pigment from dry powder to concentrated slurry form, and adjusts the water content parameter to optimize both pigment concentration and transport efficiency. The slurry is formulated with controlled water content to achieve high pigment loading while maintaining pumpability and storage stability.
Solution Approach 2:
The patent creates a composite slurry system combining titanium dioxide pigment with water and dispersants. This composite formulation allows high pigment concentration while the dispersant package prevents aggregation, enabling efficient transport and storage without requiring complete drying of the slurry.
2Quantity of substance
If lower solids slurries are used, then water content is reduced, but costly and time-consuming drying is required to remove excess water
Solution Approach 1:
The patent performs preliminary dispersion and stabilization of the titanium dioxide particles in the slurry formulation before shipping. The dispersant package is pre-applied to particle surfaces to prevent aggregation during storage and transport, eliminating the need for time-consuming drying processes while maintaining controlled water content.
Solution Approach 2:
The patent introduces a dispersant package as an intermediary substance that mediates between the titanium dioxide particles and water. This dispersant system prevents particle aggregation and stabilizes the slurry, allowing the slurry to be shipped in a semi-concentrated form without requiring complete water removal, thus reducing drying time and costs.
3Stability of the object's composition
If pigments are dispersed homogeneously, then paint stability is improved, but complex wetting and deaggregation processes are required
Solution Approach 1:
The patent employs a dispersant package as an intermediary that facilitates homogeneous dispersion of titanium dioxide particles in the paint vehicle. This dispersant system simplifies the wetting and deaggregation processes by pre-coating particle surfaces, enabling stable homogeneous dispersion without requiring complex multi-step processing.
Solution Approach 2:
The patent performs preliminary surface treatment of the titanium dioxide particles by applying the dispersant package before incorporation into the paint formulation. This pre-dispersant application simplifies subsequent wetting and deaggregation processes, leading to homogeneous dispersion and stable paint composition without requiring complex processing steps.
