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.

One of the most remarkable aspects of titanium dioxide is its versatility. It is commonly used as a pigment in paints, coatings, and plastics due to its excellent whiteness, brightness, and opacity. In these applications, titanium dioxide helps to create vibrant and long-lasting colors while also providing durability and resistance to weathering.

In addition to producing TiO2 pigment, some factories also offer custom blending and color matching services to meet the specific requirements of their customers. This allows industries such as paint manufacturers to create unique shades and colors by blending different pigments to achieve the desired results.

Lithopone was discovered in the 1870s by DuPont. It was manufactured by Krebs Pigments and Chemical Company and other companies.^[2] The material came in different seals, which varied in the content of zinc sulfide. Gold seal and Bronze seals contain 40-50% zinc sulfide, offering more hiding power and strength.^[3] Although its popularity peaked around 1920, approximately 223,352 tons were produced in 1990. It is mainly used in paints, putty, and in plastics.^[1]

Despite these positive developments, challenges remain for TiO2 factories. One major issue is the depletion of high-grade ilmenite ore, which is the primary source of titanium for producing TiO2. This has led some factories to explore alternative sources of titanium, such as upgrading lower-grade ores or。，，TiO2，。

Exposure routes are the pathways that allow ingredients to enter our bodies. Primary exposure routes include:

The use of lithopone in rubber products extends beyond mere coloration. Its unique chemical composition allows it to act as an effective UV stabilizer, protecting rubber from the degradative effects of sunlight exposure. Furthermore, lithopone contributes to enhancing the strength and durability of rubber compounds. Its fine particle size and uniform dispersion within the rubber matrix lead to improved stress distribution, thereby reducing the likelihood of cracks and fractures under mechanical strain.

The production process of titanium dioxide involves several stages, starting with the extraction of raw materials from mineral ores such as ilmenite, rutile, and anatase. These ores are then processed through various methods, including the sulfate and chloride processes, to produce high-purity titanium dioxide powder. The sulfate process involves treating the ore with sulfuric acid to extract titanium dioxide, while the chloride process uses chlorine gas to produce a purer form of the pigment.
