- Environmental considerations are paramount in these facilities. Waste management strategies are put in place to minimize the environmental footprint. For instance, waste acids generated during the sulfate process can be treated and reused, reducing both cost and environmental impact. Moreover, energy efficiency is a key focus, with many factories investing in renewable energy sources to power their operations.

- List of inorganic pigments
- The majority of the world's production of titanium dioxide goes into the manufacturing of paints, coatings, plastics, paper, and ink. As a pigment, it boasts high refractive index properties that provide exceptional opacity and brightness, making it ideal for enhancing the durability and appearance of products. Moreover, titanium dioxide's stability and ability to withstand high temperatures mean it can be used in exterior paints designed to resist fading caused by sunlight exposure.

Polyvinyl butyral (PVB) is dissolved into 12 ~ 14% solution with ethanol and made into film. It is used for printing paper film of ceramic (or enamel) products. The fired ceramic (or enamel) patterns have bright color and smooth texture. The flower paper is characterized by convenient use, low cost, smaller than the original glue, greatly reducing the decal process and high color burning rate. At present, most porcelain factories in China have formed relatively formal production lines for standardized production. Therefore, the demand for PVB in the ceramic (or enamel) flower paper industry is increasing.
Application field of polyvinyl butyral -- electronic adhesive
Polyvinyl butyral contains hydroxyl, vinyl acetate and butyraldehyde, which has high bonding properties. Phenolic Resin was added into PVB ethanol solution to make adhesive, which can be used for a long time at 120 ℃. The product has strong adhesion to metal, wood, leather, glass, fiber and ceramics; FRP can be manufactured to replace non-ferrous metals such as steel, aluminum and copper; The adhesive made by adding this product and curing agent into epoxy resin is often used for bonding and assembly of electronic instrument components, bonding between metal and porous materials, emergency repair, etc. it can also be used in the field of electronic ceramics. In the development of ceramic integrated electronic circuits, this product with medium viscosity and low hydroxyl is used as ceramic powder adhesive to increase the primary strength of ceramics.
Application field of polyvinyl butyral -- copper foil adhesive
Polyvinyl butyral (PVB) and phenolic resin cooperate to produce copper foil adhesive, which is used in the production of copper clad laminate. It has good peel strength and tin welding temperature resistance, and is widely used in various fields.
Application field of polyvinyl butyral - self adhesive enamelled wire paint
Polyvinyl butyral is the main raw material of self-adhesive enamelled wire paint. After the enameled wire is wound and formed in the electrodes of motors, electrical appliances and instruments, as long as it is heated for several minutes at a certain temperature or treated with appropriate solvent, the coils can be bonded together by themselves without impregnation and drying. -
Is titanium dioxide illegal in other countries?

In order to contribute with experimental evidence that could help to achieve a better understanding of the field for future regulation, in the present work, the biocompatibility of commercial P25TiO2NPs (one type of TiO2NPs used in sunscreen formulations) and two novel functionalized P25TiO2NPs were evaluated under solar simulated irradiation. White light, generated by red, blue, and yellow LEDs, together with UV ones, was chosen to simulate the solar spectra. Functionalization of TiO2NPs was made with antioxidant vitamins in order to prevent the expected photo-initiated ROS production when nanoparticles are exposed to the simulated solar spectra. Vitamin B2 (riboflavin) and vitamin C were chosen to carry out the functionalization because they are water-soluble, low-cost, and are a constitutive part of biological processes. In addition, it is known that both have the potential to prevent macromolecular oxidation by ROS [23], [24], [25], [26].
In the context of titanium dioxide determination, the process generally begins with the sample preparation, where a known mass of the sample containing TiO2 is dissolved or digested appropriately. The subsequent steps involve adding a precipitating agent, such as ammonium sulfate or sulfuric acid, to the prepared solution, which facilitates the formation of a titanium precipitate. This precipitate is often titanium hydroxide, which is not only insoluble but can be easily filtered out from the liquid phase.
One of lithopone's outstanding characteristics is its exceptional whiteness. The pigment has a brilliant white color that brings vibrancy and brightness to any application. Whether you are producing paints, coatings, plastics, rubber or printing inks, lithopone will ensure that your end product stands out with its unrivaled pure white shade.
European food safety regulators have since labeled titanium dioxide as no longer safe for human consumption, due to its potential toxicity.
The calcined product obtained by the ordinary zinc-barium white preparation method is beaten into a slurry, which is then surface-treated with sodium silicate, aluminum sulfate or sodium aluminate and surfactant, and then filtered, washed, dried and pulverized. Can.
We’re most often exposed to E171 through the foods we ingest. We find E171 in many food products, like popsicles, ice cream, gum, and more. Another way we ingest E171 is through pharmaceutical drugs. Many pills and capsules contain E171 as an inactive ingredient.

Food safety experts in the European Union (EU) have recently updated their safety assessment of TiO2 as a food additive. In Europe, TiO2 is referred to as E171, in accordance with European labelling requirements for food additives. The EU expert panel took into account toxicity studies of TiO2 nanoparticles, which to this point had not been considered relevant to the safety assessment of TiO2 as a food additive.
Barium sulphate, a chemical compound with the formula BaSO₄, is widely recognized for its numerous applications in various industries, particularly in the field of medicine, paints, plastics, and as a component in drilling fluids. One of the distinguishing features of barium sulphate is its striking physical property its color. Understanding the color of barium sulphate not only helps in identifying the compound during handling but also plays a significant role in its applications and quality assessment.
