Based on this opinion, the European Commission and the Member States agreed to remove all uses of titanium dioxide as an additive in food. In January 2022, a Regulation withdrawing the authorisation to use titanium dioxide as a food additive in food products was adopted i.e. Commission Regulation (EU) 2022/63.

Wholesale TI02 powder plays a critical role in photocatalysis, a process that harnesses sunlight to drive chemical reactions

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.

Pure PVB is non-toxic and harmless to human body. In addition, ethyl acetate or alcohol can be used as solvent, so PVB is widely used in printing ink of food containers and plastic packaging in European and American countries.

Storage safety properties

PVB can be stored for two years without affecting its quality as long as it is not in direct contact with water; PVB shall be stored in a dry and cool place and avoid direct sunlight. Heavy pressure shall be avoided during PVB storage.

Solubility

PVB is soluble in alcohol, ketone, ester and other solvents. The solubility of various solvents changes according to the functional group composition of PVB itself. Generally speaking, alcohol solvents are soluble, but methanol is more insoluble for those with high acetal groups; The higher the acetal group, the easier it is to dissolve in ketone solvents and ester solvents;

PVB is easily soluble in cellosolve solvents; PVB is only partially dissolved in aromatic solvents such as xylene and toluene; PVB is insoluble in hydrocarbon solvents.

Viscosity characteristics of PVB solution

The viscosity of PVB solution is greatly affected by the formula of solvent and the type of solvent; Generally speaking, if alcohol is used as solvent, the higher the molecular weight of alcohol, the higher the viscosity of PVB solution;

Aromatic solvents such as xylene and toluene and hydrocarbon solvents can be used as diluents to reduce the viscosity of PVB solution; The effect of PVB chemical composition on viscosity is summarized as follows: under the same solvent and the same content of each base, the higher the degree of polymerization, the higher the solution viscosity; Under the same solvent and the same degree of polymerization, the higher the acetal group or acetate group, the lower the solution viscosity.

Dissolution method of PVB

Where mixed solvents are used, the dissolution step is to first put aromatic solvents (such as xylene, toluene, etc.) or ester solvents (such as n-butyl acetate, ethyl acetate, etc.) into the mixing, slowly put PVB into the mixing, and then add alcohol solvents (such as n-butanol, ethanol, etc.) after PVB is dispersed and expanded,

At this time, the dissolution time can be shortened by heating; Using this dissolution method, the formation of lumpy PVB can be avoided (because the dissolution time will be several times after the formation of lumpy PVB), so the dissolution speed can be accelerated. Generally, the ratio of aromatic and alcohol solvents is 60 / 40 ~ 40 / 60 (weight ratio), and PVB solution with low viscosity can be prepared.

The solvent composition contains 2 ~ 3wt% water, which can improve the hydrogen bonding strength of alcohol solvents and help the solubility of PVB.

Processing properties

Although PVB resin is a thermoplastic, it has little processability before plasticizer is added. Once plasticizer is added, its processability is very easy.

The purpose of general coatings and adhesives is to change the resin characteristics by adding plasticizers to meet the application requirements, such as film softness, reducing the TG point of the resin, reducing the heat sealing temperature, maintaining low-temperature softness, etc.

Compatibility

PVB can be compatible with a variety of resins, such as phenolic resin, epoxy resin, alkyd resin and MELAMINE resin.

B-08sy, b-06sy and b-05sy with high acetal degree can be mixed with nitrocellulose in any proportion. PVB and alkyd resin are partially compatible. General PVB is compatible with low molecular weight epoxy resin, while high molecular weight epoxy resin needs PVB with high acetal degree to be compatible with each other.

In conclusion, China's dominance in the titanium dioxide industry brings both economic benefits and environmental challenges. The country's commitment to reducing CO2 emissions through technological advancements and policy interventions is a step towards a more sustainable future. However, the journey ahead necessitates a delicate balance between industrial growth and environmental responsibility, making China's experience a significant case study for the global transition to a low-carbon economy.

After drying, the sample is weighed precisely, and through stoichiometric calculations, the amount of titanium dioxide in the original sample can be determined. The resulting calculation helps determine the gravimetric percentage of titanium dioxide present, providing manufacturers with critical information for quality control.

However, other countries like the United States, Japan, and Germany also have notable lithopone producers. These companies, although operating on a smaller scale, often offer higher quality products with specialized grades tailored to specific industries. For instance, American company Huber Engineered Materials and German-based Merck KGaA are renowned for their high-performance lithopone products.

Manufacturers of latex paints recognize the importance of incorporating rutile TiO2 into their formulations. This form of titanium dioxide imparts excellent opacity, which is crucial for achieving uniform coverage and concealing underlying surfaces effectively. The ability to hide imperfections with fewer coats not only saves time but also reduces material costs, contributing to more efficient and economical painting projects.

There are several factors that can affect the pricing of lithopone pigment. The quality of the product, the source of the raw materials, and the production process all play a role in determining the final cost. Additionally, market conditions and demand can also impact pricing.

In a review published in 2022 in the journal Archives of Toxicology, researchers found that the ingestion of E171 is a “a definite health risk for consumers and their progeny.” After reviewing dozens of in vivo, ex vivo and in vitro studies on the toxicity of E171, the researchers wrote that two facts must be noted: “First, reprotoxicity studies show that animals of both sexes are impacted by the toxicity of these nanoparticles, underlining the importance of conducting in vivo studies using both male and female animals. Second, human exposure begins in utero via maternal-fetal transfer and continues after birth by breastfeeding. Children are then chronically re-exposed due to their food preferences. To be relevant to the human in vivo situation, experimental studies should therefore consider nanoparticle exposure with respect to the age or life period of the studied population.”
