  • Another crucial property of TiO2 is that it can show photocatalytic activity under UV light. This makes it effective for environmental purification, for different kinds of protective coatings, sterilisation and anti-fogging surfaces, and even in cancer therapy.

  • In conclusion, titanium dioxide is a versatile and indispensable material that plays a crucial role in various industries. Its unique properties make it an ideal choice for use as a pigment, photocatalyst, semiconductor material, and more. As technology continues to advance, the demand for titanium dioxide is likely to increase, making it an essential material for the future.
  • Regulatory agencies around the world are currently working to establish guidelines for the safe use of TiO2 in consumer products and water supplies. In the meantime, consumers can take steps to minimize their exposure to TiO2 by choosing products that do not contain the pigment and using water filters that can remove nanoparticles.
  • In addition to paints and coatings, titanium oxide is also used in the production of ceramics. It is added to ceramic glazes to give them a smooth, glossy finish and to improve their durability. Titanium oxide is also commonly used in the production of glass, where it helps to provide clarity and strength.
  • In conclusion, the determination of barium as TiO2 in industrial factories requires a combination of analytical techniques depending on the specific requirements of the application. Each method has its own advantages and limitations, and the choice of technique should be based on factors such as accuracy, precision, cost, and turnaround time. With the proper selection and implementation of these techniques, manufacturers can ensure the quality and safety of their products while complying with environmental regulations.

  • 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, titanium dioxide is an integral part of coatings factories, transforming the quality and functionality of coatings. Its role as a pigment not only adds aesthetic appeal but also provides crucial protection against environmental factors. As technology advances, the coatings industry will likely continue to harness the full potential of TiO2, ensuring its continued dominance in the sector.

  • 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.”
