3000 Mesh Barium Sulate's Taste and Texture

3000 mesh barium sulate is a kind of white powder without any taste.Its specific gravity is 4.20.It is chemically inert and insoluble in water,alcohol,or many other solvents,except hot concentrated sulfuric acid.

Barium sulfate suspensions could be described as having the consistency of a very thick glass of milk, or a very thin milkshake. Liquid chalk, with a not too unpleasant medicinal taste, is more accurate. The suspension is homogeneous, perfectly smooth, and white in color - very much like the color of milk. The suspension is stored at room temperature (labels suggest 25°C), so "warm, thick milk" is a common description of the general weight and consistency of the drink.

The taste is generally considered unpleasant, but not unbearably repulsive, and is dependent on the exact makeup of the drink. Descriptions range from "poor tasting, very runny vanilla pudding" to "mildly citrus, with a strong bitter aftertaste". In addition, the presence of the barium sulfate makes the drink have a mild acidic burning sensation. Because of the ease of the actual test, the paced two-hour consumption of the barium sulfate suspension is often considered the worst part of a CT scan.

Powder coating is a type of coating that is applied as a free-flowing, dry powder. The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form. The coating is typically applied electrostatically and is then cured under heat to allow it to flow and form a "skin". The powder may be a thermoplastic or a thermoset polymer. It is usually used to create a hard finish that is tougher than conventional paint. Powder coating is mainly used for coating of metals, such as "whiteware," aluminium extrusions, and automobile and bicycle parts. Newer technologies allow other materials, such as MDF (medium-density fibreboard), to be powder coated using different methods.

Although soluble salts of barium are moderately toxic to humans, barium sulfate is nontoxic due to its insolubility. The most common means of inadvertent barium poisoning arises from the consumption of soluble barium salts mislabeled as BaSO4. In the Celobar incident (Brazil, 2003), nine patients died from improperly prepared radiocontrast agent.

A Simple Description of Ultra-fine Modified Precipitated Barium Sulfate for General Use

Ultra-fine modified precipitated barium sulfate for general use is a type of white powder without any taste.Its specific gravity is 4.20.Is the highest of the minerals.It is chemically inert and insoluble in water, Alcohol,or many other solvents,except hot concentrated sulfuric acid.

Recently, the preparation of barium sulfate, BaSO4, has received considerable attention for its applications in such areas as ceramics, pigments and fillers for polymers. The method of preparing a powder and processing a controlled morphology is an important problem in material science. In order to inhibit crystallization process and to modify the morphology of crystalline product, many different methods have been reported for synthesis of BaSO4  including the addition of different additives and microemulsions. (Poly)phosphonate- and polycarboxylate-type additives are commonly applied to retard the unwanted deposition of inorganic ormineral salts. Such inhibitors have the ability to form a sufficient number of coordinative bonds with cations on the mineral surface. In general, the reaction media was mainly aqueous solution and the addition of additives can cause a significant change in morphology, but the obtained BaSO4 crystals in size are generally ordered on the micron scale rather than the nanometer scale. Water-in-oil (w/o) microemulsions or reverse micelle have been used for the synthesis of inorganic nanoparticles of metal sulfate, barium chromate. The principal reason for using microemulsions is that the particle size and the corresponding morphology can be well controlled by varying the molar ratio of water to surfactant. However, the salt amount solubilized in conventional microemulsions is relatively low; it is not advantageous to get a high product yield.

As barium sulfate has high burning point and is insoluble in water, it is used as a coating material in casting of copper anode plates. The anode plates are cast in copper molds, so to avoid the contact of the liquid copper and the solid copper mold, a solution of barium sulfate in water is used as a coating material on the mold surface. Thus when the liquid copper solidifies in form of an anode plate it can be easily removed from its mold.

The Safety of Triglycidyl Isocyanurate

 Triglycidyl isocyanurate is toxic by inhalation and if swallowed. It is a severe eye irritant, and a mild skin and nasal irritant. Both pure TGIC, and TGIC-containing powder coatings have the potential to cause skin sensitisation in people which can lead to severe skin rashes. The effects of repeated long-term exposure to TGIC have not been well studied, but kidney damage has been observed in rats repeatedly exposed to TGIC by oral dosing, and damage to the developing sperm cells has been observed in mice repeatedly exposed to TGIC orally and by inhalation.
There is animal evidence that exposure of males to TGIC produces genetic changes in the sperm which may lead to heritable effects in the offspring. There is cause for concern that these effects could occur in humans, so that TGIC has been classified in the EU as a Category 2 mutagen. The reproductive toxicity of TGIC has not been well studied. Information on the health effects of TGIC is published in HSE guidance Note EH64 (1997 supplement).
