Before storing your cast iron cookware, make sure it's clean. Use warm water and a stiff brush to remove any food residue. Avoid using soap, as it can strip away the seasoning. After washing, dry your cookware completely using a towel or by placing it over low heat on a stove. Moisture can lead to rust, which is the enemy of cast iron.

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, the rutile type TiO2 stands out for its robust physical and chemical properties, which translate into a myriad of practical applications. From enhancing the performance of industrial coatings to aiding environmental clean-up efforts, rutile continues to be a cornerstone material in modern industry and science. As research progresses, it is likely that new uses for this remarkable substance will be discovered, further cementing its status as a versatile and indispensable material.
Though the regulated use of titanium dioxide in food products is legal in the U.S. and Canada, it's banned in some other countries, notably throughout Europe. In May 2021, the European Food Safety Authority announced that titanium dioxide can no longer be considered safe as a food additive.
3. The calcined product obtained by the ordinary zinc bismuth method is slurried into a slurry, which is sequentially treated with sodium silicate, aluminum sulfate or sodium aluminate and a surfactant, and then filtered, washed, dried and pulverized.
In both processes, the size of the pigment particles as well as the post-treatment is adjusted by fine-tuning the final steps in the chemical route.
Titanium Dioxide Rutile Tio2 POWDER Titanio Dioxide Pigment- However, challenges remain for China's talc and titanium dioxide industry. Environmental concerns surrounding the mining and processing of these minerals have led to increased scrutiny from both domestic and international regulators. Additionally, competition from other countries with abundant reserves of these minerals could potentially limit China's market share in the future. Despite these challenges, China's role in the global talc and titanium dioxide market is expected to remain significant, as the country continues to invest in its mining infrastructure and explore new applications for these versatile minerals.

1. Paints and Coatings Due to its excellent opacity and brightness, anatase TiO2 is extensively used as a pigment in paints. The high refractive index of this compound allows for better coverage and durability, making it an essential component in decorative and protective coatings.
No acute effects of nano-sized TiO2 were observed in Danio rerio (zebrafish) embryos. Exposure of rainbow trout to TiO2 NPs triggered lipid peroxidation, influence on the respiratory tract, disturbance in the metabolism of Cu and Zn, induction of intestinal erosion and accumulation in kidney tissue. Linhua et al. exposed juvenile carp to 100 and 200 mg/ml of particles and TiO2 observed no mortality. However, the fish suffered from oxidative stress and pathological changes in gill and liver. In the infaunal species Arenicola marina, exposure to TiO2 NPs in sediment caused sub-lethal effects including decrease in casting rate and increase in cellular and DNA damage. Aggregated particles were visible in the lumen of the gut, but no uptake through the gut or the skin was observed.

- The first step in obtaining titanium dioxide typically begins with the mining of ilmenite, rutile, and anatase – minerals that contain titanium. These minerals are extracted from the earth through open-pit or underground mining methods. Once mined, they undergo beneficiation processes such as crushing, grinding, and gravity separation to concentrate the titanium-bearing ore.
36 In food, titanium dioxide has a few different uses. Most notably, its food-grade form is used as a colorant to enhance and brighten the color of white foods such as dairy products, candy, frosting, and the powder on donuts. For foods that are sensitive to UV light, titanium dioxide is used for food safety purposes to prevent spoilage and increase the shelf life of food.
- One of the most significant uses of titanium dioxide is in the production of paints and coatings. It acts as a pigment that provides brightness, opacity, and durability to the final product. The high refractive index of titanium dioxide allows it to scatter light effectively, making it ideal for creating opaque finishes. Moreover, its chemical stability ensures that the color remains consistent over time, even when exposed to harsh environmental conditions.
The uses and applications of Titanium Dioxide may vary according to its specification. The main forms of Titanium Dioxide are dependent on particle sizes, surface treatment, and crystalline forms.
Titanium dioxide (TiO2) is a multifunctional semiconductor that exists in three crystalline forms: anatase, rutile, and brookite. Owing to an appropriate combination of physical and chemical properties, environmental compatibility, and low production cost, polycrystalline TiO2 has found a large variety of applications and is considered to be a promising material for future technologies. One of the most distinctive physical properties of this material is its high photocatalytic activity (Nam et al., 2019); however, more recently it has attracted growing interest because of its resistive switching abilities (Yang et al., 2008).
