Vitamin K-related information

Vitamin K is a group of naphthoquinone derivatives 2 - menadione, is a human vitamins, with a hydrophobic. It is a special post-translational protein necessary, particularly in the blood coagulation protein necessary. Vitamin K2 (menaquinone (Menaquinone) and four Menatetrenone (Menatetrenone)) is usually manufactured by bacteria in the intestines of animals, so vitamin K deficiency is extremely rare unless there is severe intestinal damage. In addition to natural vitamin K1, K2, there are also synthetic vitamin K3, K4.
Vitamin K is a family of compounds of similar structure, their common methylated naphthoquinone ring, but at position 3 of the hydrocarbon side chain is different. Phylloquinone (Phylloquinone. Also known as vitamin K1) with the side chain of four isoprene (isoprenoid) residues, one of which is unsaturated known. Menadione (Menaquinone, vitamin K2) an unsaturated side chain known unequal number of isoprene chains, commonly referred to as MK-n, n represents the number of isoprene chains. MK-4, 5,7 equal activity with vitamin K1. MK-1 only 1% of the activity of vitamin K1, MK-10 is only 30 to 49% of the active. Menadione (Menadione, vitamin K3) is a synthetic product, but with toxicity.

A brief history of the discovery of Sulphur

Sulfur (Sulphur) is a non-metallic element, chemical symbol is S, atomic number is 16. Sulfur Sulphur is a very common nonmetallic tasteless, pure sulfur is yellow crystals, also known as sulfur. In nature it is often in the form of sulfide or sulfate, pure sulfur in volcanic areas are also appearing in nature. It is an integral part of many amino acids. Mainly used in fertilizers, gunpowder, lubricants, pesticides and the production of anti-fungal agents. Generating combustion of sulfur dioxide in the air with oxygen and water to form sulfuric acid, causing acid rain.
Around 4,000 years ago, the Egyptians would have been formed by the combustion of sulfur dioxide to bleach cloth, the ancient Greeks and Romans also be proficient in the use of sulfur dioxide fumigation and bleaching. The ninth century BC, the Roman poet Homer in his writings about the sulfur burning when disinfecting and bleaching effect.
In ancient China, the first pharmaceutical monograph "Shen Nong's Herbal Classic" [1], contained in the animals, plants and minerals up to 365 kinds of medicines, contained 46 kinds of minerals in drugs, there are stone sulfur (ie sulfur). In this book there is also pointed out: "Stone sulfur can turn Yellow Gold iron, strange things." This shows that the sulfur was already known to work with copper, iron and other metals to form metal sulfides directly. World's oldest extant writings alchemy - Wei Boyang of the "Kinship" [2], but also chronicles the sulfur and volatile mercury can be less volatile mercury sulfide synthesis. Chinese study for gunpowder, probably began in the seventh century AD. Then black gunpowder gunpowder, which is composed of potassium nitrate, sulfur and charcoal composed of three. Sulfur is an important component of black powder was.
With the 1746 British J.Roebuck lead chamber method invented in 1777 manufacture of sulfuric acid and sulfur by the French ALLavoisier recognized as an element, the sulfur will enter the gates of modern chemistry. After this time, the sulfur is fast becoming the modern chemical industry and the modern chemical industry is closely related to one of the most important elements. Latin name Surphur estimates of sulfur from India Sanskrit Sulvere, the original meaning is bright yellow.

Zinc Oxide 99.7% of the usage history

Zinc oxide (ZnO), commonly known as zinc white, a zinc oxide. Insoluble in water, soluble in acid and alkali. Zinc oxide is a commonly used chemical additives, is widely used in plastics, silicate products, synthetic rubber, lubricants, paints, ointments, adhesives, food, batteries, flame retardants and other products production. Zinc oxide bandgap and a large exciton binding energy, high transparency, excellent performance often Wen Faguang in the semiconductor field of liquid crystal display, thin film transistors, light emitting diodes and other products are applied. Furthermore, zinc oxide fine particles as a nano-material in the relevant fields have begun to play a role.
Using History
Early humans learned to use it as a paint or zinc oxide topical medicine, but the history of mankind discovered zinc oxide has been difficult to trace.
In ancient Indian medicine book "Chakra The collection" describes a zinc oxide after being identified as a drug, used to treat eye diseases and injuries. 1st century AD Greek physician Dioscorides Clerides also mentioned to do with zinc oxide ointment. Avicenna completed in 1025, "Hui prescription" will be described as zinc oxide to treat various skin disorders, including skin cancer drug of choice. Nowadays, people are no longer using zinc oxide cure skin cancer, it is still widely used to treat other common skin disorders.
Romans as early as 200 BC, they learn how to use copper and zinc ore containing zinc oxide reaction produced brass. Zinc oxide zinc in the shaft furnace turned into steam, rolled into the flue react. Dioscorides Clerides also been introduced to this.
12th century onwards, the Indians know the zinc and zinc, and began using zinc smelting original way. Zinc smelting technology was introduced to China in the 17th century. 1743, Bristol, England, established the first European zinc smelting factory.
Another major use of zinc oxide is used as a coating, known as zinc white. In 1834, zinc white first became watercolor paints, but zinc white insoluble oil. But soon the problem of zinc oxide produced by the new process solutions. In 1845, in Paris, Leclerc began mass production of zinc white oil paint, to 1850, zinc white became popular throughout Europe. High purity zinc white, so that in the 19th century, some artists in painting painted zinc white as a background, however, after a hundred years later, these paintings are showing cracks.
In the latter half of the 20th century, zinc oxide is used in the rubber industry. In the 1970s, the second largest use of zinc oxide is copy paper additives, but in the 21st century, zinc oxide additive approach for copy paper has been eliminated.

Shipbuilding Plate Background and uses

Shipbuilding Plate refers to special structural steel shipbuilding production for the manufacture of the ocean, coastal and inland navigation ship hull structure steel sheets and thick steel plate.

Background:
Since 2011, the international shipping market downturn, shipbuilding overcapacity, resulting in the shipbuilding industry has entered a "winter period."
Experts pointed out that the international financial crisis, the impact of lag, shipbuilding real crisis has only just arrived, the current new orders declined significantly impact the next three years will be gradually upgraded. Authoritative data show that the first three quarters of last year, about 30% of the national shipyard did not receive new orders and new ship prices than last year before the financial crisis Heavy 30% -40%. Let shrinking shipbuilding shipbuilding plate market also suffered a weakness.

Purpose:
Shipbuilding plate is mainly used for domestic shipbuilding industry. Shipbuilding plate by different rolling equipment production, China's shipbuilding plate production with the development of shipbuilding industry composition is also changing, due to the different properties of the products rolling equipment there is a difference, shipbuilding plate prices are not the same, and in a certain market supply and demand environment more clearly reflected.
