Use of Stainless steel powder

Submitted by admin on Fri, 11/09/2018 - 07:48

Metal stainless steel powder made of a stainless steel alloy.

The particle shape of stainless steel powder was a regular spherical shape with a density of 7.9 g/cm 3 and an average particle diameter of <33 μm. It has good corrosion resistance and durability. Its spherical particles can be positioned parallel to the surface of the coating film and distributed throughout the coating film to form a shielding layer with excellent hiding power to block moisture.

Use of Titanium

Submitted by admin on Thu, 11/08/2018 - 09:13

Pure titanium is a silvery white metal with many excellent properties. Titanium has a density of 4.54 g/cm3, which is 43% lighter than steel and slightly heavier than the long-established light metal magnesium. The mechanical strength is similar to steel, twice as large as aluminum and five times larger than magnesium. Titanium is resistant to high temperatures and has a melting point of 1942K, which is nearly 1000K higher than gold and nearly 500K higher than steel.

What is the Metal Titanium

Submitted by admin on Thu, 11/08/2018 - 09:08

Titanium looks like steel, has a silver-gray sheen, is a transition metal that has been considered a rare metal for some time. Titanium is not a rare metal. Titanium accounts for about 0.42% of the total weight in the earth's crust, which is 16 times the total amount of copper, nickel, lead and zinc. Ranked seventh in the metal world, with more than 70 minerals containing titanium. Titanium has high strength, low density, high hardness, high melting point and strong corrosion resistance; high-purity titanium has good plasticity, but becomes brittle and hard when impurities are present.

What is Mercury-II-chloride

Submitted by admin on Wed, 11/07/2018 - 08:33

Mercury-II-chloride, the molecular formula is HgCl2, colorless or white crystalline powder, a small amount of volatile at room temperature. Soluble in water, ethanol, ether, methanol, acetone, ethyl acetate, insoluble in carbon disulfide, pyridine. Long-term work in an environment where the mercury vapor content in the air exceeds the allowable range can cause chronic poisoning, and there are mental disorders such as memory loss, salivation, fatigue, fatigue, insomnia, and dizziness. Heavier fingers and tongue tremors appear. After poisoning, the stomach should be washed.

Different between Mercury (II) oxide red and yellow

Submitted by admin on Wed, 11/07/2018 - 07:59

Mercury oxide(mercury oxide (II)) is an alkaline oxide, inorganic, chemical formula HgO, bright red or orange-red scaly crystal or crystalline powder, almost insoluble in water, insoluble in ethanol, at 500 ° C break down. Very toxic and irritating. Mercury oxide can be used to make other mercury compounds, as well as catalysts, pigments, antibacterial agents and electrode materials in mercury batteries.

What is Manganese carbonate

Submitted by admin on Wed, 11/07/2018 - 07:37

Manganese carbonate is a raw material for the manufacture of soft ferrites for telecommunications equipment, synthesis of manganese dioxide and manufacture of other manganese salts. Used as a catalyst for desulfurization, pigments for enamels, coatings and varnishes. Also used as a fertilizer and feed additive. Used in medicine, welding electrode accessories, etc., used as raw materials for the production of electrolytic manganese metal.

Main use of Tin Tetrachloride

Submitted by admin on Wed, 11/07/2018 - 06:44

Tin Tetrachloride is a colorless, flowable liquid with gas molecules in a regular tetrahedral configuration. The bond length is Sn-Cl 228pm. The temperature of -33 ° C, the boiling point of 114.1 ° C. The density is 2.226 g/cm3. It is miscible with carbon tetrachloride, ethanol and benzene. It is easily soluble in water and soluble in most organic solvents such as gasoline, carbon disulfide and turpentine. Slowly add water to form a colloid of SnO2 and hexachlorostannic acid [H2[SnCl6]].

What is the manganese hydrogen phosphate

Submitted by admin on Mon, 11/05/2018 - 09:12

Manganese hydrogen phosphate is one of the natural ingredients of almost all foods and is widely used in food processing as an important food ingredient and functional additive. It is a salt of phosphoric acid and is an important substance in inorganic chemistry, biochemistry and biogeochemistry.

The naturally occurring Manganese hydrogen phosphate is a phosphate rock (including Manganese hydrogen phosphate) which is reacted with phosphate rock to form calcium dihydrogen phosphate and calcium sulfate which can be absorbed by plants to produce Manganese hydrogen phosphate.

Use of manganese hydrogen phosphate

Submitted by admin on Mon, 11/05/2018 - 09:07


Chemical fertilizer industry
Manganese hydrogen phosphate is generally used in detergents as a water softener, but in some areas manganese hydrogen phosphate cleaners are regulated because of the prosperous decay cycle of algae that affects phosphate discharge in watersheds.

There are generally three numbers of fertilizer grades: the first refers to the amount of nitrogen, the second refers to the amount of manganese hydrogen phosphate, and the third refers to alkaline water.
