Industrial Applications of Rutile
| Industry | Application | Process |
|---|---|---|
| Coatings | Primary white pigment providing high hiding power and whiteness | Production of titanium dioxide via the sulfate or chloride process, followed by surface treatment (e.g., alumina or silica coating) and dispersion into resin matrices |
| Plastics | White coloration and ultraviolet (UV) protection | Blending titanium dioxide with polymers (e.g., PVC, PE, PP), followed by melt extrusion or injection molding |
| Papermaking | Enhancement of paper whiteness, opacity, and printability | Addition of titanium dioxide to pulp, followed by papermaking and calendering to produce high-whiteness paper |
| Inks | White pigment improving ink hiding power and gloss | Grinding and dispersing titanium dioxide with resins, solvents, and additives to formulate white ink systems |
| Cosmetics | Physical UV filter and white colorant | Surface-treated titanium dioxide (e.g., with polydimethylsiloxane) dispersed into emulsions, foundations, and other cosmetic bases |
| Food | Food additive E171 (banned in some countries) for whitening | Use of food-grade titanium dioxide, ultra-finely milled and incorporated into confectionery, chewing gum, sauces, and similar products |
| Textiles | Fiber whitening and UV protection | Incorporation of titanium dioxide as masterbatch or slurry into synthetic fiber (e.g., polyester) spinning processes |
| Ceramics | Glaze additive enhancing whiteness and gloss | Mixing titanium dioxide with silicate-based glazes, followed by high-temperature firing to yield white ceramic surfaces |
| Rubber | Improvement of product whiteness and weather resistance | Blending titanium dioxide with rubber latex or compounded rubber, followed by vulcanization and molding |
| Construction Materials | Used in white cement, putties, and exterior coatings | Mixing titanium dioxide with cement, lime, and fillers, followed by mixing, spraying, or plastering during application |
Manufacturing Quality Control of Rutile
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Titanium Content (TiO₂ Purity) | Chloride Titration Method, ICP-OES | Dissolve the sample chemically, then determine TiO₂ content using chloride reduction titration or inductively coupled plasma optical emission spectrometry (ICP-OES). |
| Whiteness | Whiteness Meter Measurement (e.g., HunterLab, CIE Lab) | Measure the reflectance of the sample under standard light sources using a whiteness meter to calculate the whiteness value and evaluate its degree of whiteness. |
| Particle Size Distribution | Laser Particle Size Analysis | Disperse the sample in liquid or gas and use laser scattering principles to measure particle size and distribution. |
| BET Surface Area | BET Nitrogen Adsorption Method | Determine the specific surface area per unit mass of the material by physically adsorbing nitrogen at low temperatures and applying the BET theory. |
| pH Value | pH Meter Measurement | Stir the titanium dioxide aqueous suspension uniformly, then directly measure its acidity or alkalinity using a pH meter. |
| Water-Soluble Content | Gravimetric Method | Dissolve the sample in water, filter, evaporate the filtrate to dryness, weigh the residue, and calculate the percentage of water-soluble substances. |
| Sieve Residue (Impurities) | Wet Sieving Method | Wash the sample through a standard sieve (e.g., 45 μm) with water, measure the mass of residue on the sieve, and assess the content of coarse impurity particles. |
| Oil Absorption | Blade Method (DBP Absorption Method) | Gradually add DBP and mix it with titanium dioxide until a paste forms; calculate the amount of DBP absorbed per unit mass of pigment to reflect dispersibility. |
| Opacity | Brush Coating Comparison Method / Reflectance Method | Prepare a paint film from the sample and measure its ability to cover black and white substrates. Opacity is typically expressed as minimum coating thickness or contrast ratio. |
| Dispersion | Grit Fineness Meter Method / Turbidity Method | Prepare a slurry, measure the degree of particle aggregation using a fineness meter, or assess dispersion stability using a turbidimeter. |
| Impurity Elements (Fe, Si, Al, etc.) | ICP-MS or AAS | Dissolve the sample and determine trace metal impurities using inductively coupled plasma mass spectrometry (ICP-MS) or atomic absorption spectroscopy (AAS). |
| Weather Resistance | Accelerated Aging Test (e.g., Xenon Lamp Aging) | Apply the sample to a coating and subject it to aging under simulated sunlight, humidity, and temperature conditions to evaluate resistance to discoloration and chalking. |
