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. -
Barium sulfide is produced by carbothermic reduction of barium sulfate. Zinc sulfate is obtained from a variety of zinc products, often waste, by treatment with sulfuric acid.

Zhu et al. were the first to provide evidence that TiO2 NPs (21 nm) can transfer from daphnia to zebrafish by dietary exposure. Hence, dietary intake could be a major route of exposure to NPs for high trophic level aquatic organisms. Ecological research should therefore focus, not only on the concentration of NPs in the environment, but also on its bioconcentration, bioaccumulation and biomagnification. In addition it has been shown that TiO2 NPs can increase accumulation of other environmental toxicants: enhanced accumulation of cadmium (Cd) and arsenic (As) was found in carp in the presence of TiO2 NPs. The strong adsorption capacity for Cd and As was explained by the large specific surface area and strong electrostatic attraction of TiO2 NPs that contribute to facilitated transport into different organs.
- In conclusion, the anatase and rutile nano-TiO2 factory represents a microcosm of modern materials science, where cutting-edge technology, innovative chemistry, and meticulous engineering converge to produce high-value nanomaterials. As research continues to uncover new applications and improve upon existing methodologies, the future of these factories promises to be exciting and transformative, pushing the boundaries of what is possible in material synthesis and application.
The zinc content in the electrolytic zinc acid leaching residue in the leaching step is 5% to 35%. In the purification step, after the primary immersion liquid is added with ammonium persulfate for one oxidation, a polyacrylamide coagulant is added before the filtration separation. It is used for flocculation to produce arsenic and iron coprecipitation to remove harmful elements.Topical Exposure

There seems to be a lot of misunderstanding about titanium dioxide, which can be used as a colorant in foods. While headlines may suggest titanium dioxide is a health concern, scientific research has actually shown titanium dioxide to be safe. So what is it used for and why is it used? Read on to learn more!
- The pH of titanium dioxide refers to its acidity or alkalinity level, which can greatly affect its dispersibility, stability, and performance. Typically, titanium dioxide is most stable and exhibits its optimal properties at neutral pH levels, around 7.0. At this pH, the titanium dioxide particles are well-dispersed and have maximum brightness and opacity.
- The benefits of wholesale TI02 powder extend to the health and beauty industry, where it is used as a key ingredient in sunscreens and cosmetics. Its ability to deflect and scatter UV radiation protects the skin from harmful rays while ensuring that cosmetic products maintain their intended appearance without discoloration.

TiO2 powder is also widely used in the cosmetics industry, where it is used as a whitening agent in skincare products, sunscreen, and makeup. TiO2 powder suppliers work closely with cosmetic manufacturers to ensure that they have a reliable and high-quality supply of TiO2 powder to meet the demands of their consumers.
- Lithopone is a popular white pigment that is commonly used in the manufacturing of paints, inks, and plastics. It is known for its high opacity and excellent coverage, making it a preferred choice for many industries.
- As the demand for high-performance plastics continues to grow, the use of lithopone as a key additive in the industry is expected to increase. Manufacturers are constantly looking for ways to improve the quality and cost-effectiveness of their products, and lithopone offers a versatile solution to help them achieve their goals.

It is an anatase titanium dioxide pigment produced by a special process from sulfuric acid. Widely used in PVC pipes, interior coatings, industrial pigments, rubber, leather, polyolefins, Printing ink, plastic, paper, etc.
Although barium sulfate is almost completely inert, zinc sulfide degrades upon exposure to UV light, leading to darkening of the pigment. The severity of this UV reaction is dependent on a combination of two factors; how much zinc sulfide makes up the pigments formulation, and its total accumulated UV exposure. Depending on these factors Lithopone B301, Lithopone B311 powder itself may vary in shade over time, ranging from pure white all the way to grey or even black. To suppress this effect, a dopant might be used, like small amount of cobalt salts, which would be added to the formulation. This process creates cobalt-doped zinc sulfide. The cobalt salts help to stabilize zinc sulfide so it will not have as severe a reaction to UV exposure.
