Additionally, air purifiers are beneficial for those living in urban areas where traffic congestion and construction work contribute to higher pollution levels. With many people spending a significant amount of time indoors, particularly in small apartments or offices, the need for clean indoor air becomes paramount. An air purifier can act as a safeguard against the harmful effects of outdoor pollutions, such as particulate matter and volatile organic compounds (VOCs), creating a sanctuary of clean air within closed spaces.

  • 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.

  • Quality control is a vital aspect of paint pigment factories. Rigorous testing is conducted throughout the production process to ensure the pigments meet industry standards for color strength, lightfastness, and stability. This ensures that the paints made with these pigments will retain their vibrancy over time and withstand various environmental conditions.
  • Name:

  • Lithopone B301, scientifically known as zinc sulfide-barium sulfate, is a blend of two pigments - zinc sulfide and barium sulfate. It offers a cost-effective alternative to titanium dioxide, providing comparable whiteness and opacity while being less expensive. The 'B301' grade specifically refers to a variant with optimized properties for enhanced performance in different applications.
  • Our commitment to excellence starts with our state-of-the-art manufacturing facility, which is equipped with the latest technology and machinery. This enables us to produce barium zinc sulfate that meets the highest standards of purity and consistency. Our team of experienced chemists and technicians monitors every step of the production process to ensure that our products meet the highest quality standards.
  • The global demand for lithopone has been steadily increasing in recent years, driven by the growth of the construction, automotive, and electronics industrieslithopone factory in china. In addition, the increasing awareness of environmental issues has led to a shift towards more sustainable products, which has benefited the lithopone industry. However, the industry also faces challenges such as rising raw material prices and competition from alternative pigments.
  • Installing rutile TiO2 wallpaper is a breeze, thanks to its pre-pasted backing. This eliminates the need for messy glue and allows for quick and easy installation. Plus, it is removable, so if you ever decide to redecorate or change the layout of your room, you can easily remove the wallpaper without causing any damage to the wall.
  • Global Titan Tio2 suppliers cater to this diverse demand, offering high-quality products sourced from pure titanium minerals. Key players in this industry include companies like Cristal Global, Tronox, Chemours, Evonik Industries, and Venator Materials. These companies not only supply TiO2 but also engage in research and development to enhance the performance of their products.
  • While IARC listed titanium dioxide as “possibly carcinogenic to humans,” they also add that “there is inadequate evidence in humans for the carcinogenicity of titanium dioxide.” Of the four human studies that they reviewed, only one showed a potential risk for occupational workers inhaling titanium dioxide particles and lung cancer, while the other three showed no risk for cancer at all. And it’s key to note that IARC did not assess the effects of titanium dioxide found in foods.

  • One of the key challenges facing TiO2 industry suppliers is the fluctuation of raw material prices. The production of TiO2 requires raw materials such as ilmenite or rutile, which are subject to market price volatility. Suppliers must carefully monitor these fluctuations and adjust their production processes accordingly to ensure profitability.

  • In a 2016 study published in Scientifica (Cairo), Egyptian researchers examined the effects of titanium dioxide nanoparticles on the organs of mice by orally administering the food additive daily, for five days. The results showed that the exposure produced “mild to moderate changes in the cytoarchitecture of brain tissue in a time dependent manner.” Furthermore, “Comet assay revealed the apoptotic DNA fragmentation, while PCR-SSCP pattern and direct sequencing showed point mutation of Presenilin 1 gene at exon 5, gene linked to inherited forms of Alzheimer’s disease.” The researchers wrote: “From these findings, “the present study concluded that TiO2NPs is genotoxic and mutagenic to brain tissue which in turn might lead to Alzheimer’s disease incidence.”

  • The market for titanium dioxide coatings is dynamic and subject to fluctuations in demand from various industries. Exporters must stay informed about global trends and adapt to changes, such as advancements in technology or shifts in consumer preferences. They must also be prepared to navigate challenges like international tariffs and transportation costs which can affect the pricing and availability of their products.
