Zirconium salt coating crosslinking agent

Zirconium salt coating crosslinking agent,Zirconium salt crosslinking acrylic resin containing carboxylic acid, also have a very good film performance.

Coating of the application of ammonium zirconium carbonate salt can be used for water-based coating, has good heat resistance, brush try resistance and water resistance. Ammonia carbonate zinc salt crosslinking agent with ammonia neutralization of acrylic resin crosslinking reaction.

Zirconium, Zirconium) is a kind of chemical element, chemical symbol is Zr, its atomic number is 40, is a kind of high melting point metal, the pale grey. The density of 6.49 g/cm3. The melting point of 1852 + / - 2.001 ℃, boiling point 1852 ℃. Valence + 2, + 3 and + 4. The first ionization energy of 6.84 electron volts. Zirconium surface is easy to form a layer of oxide film, gloss, so the appearance is similar to steel. Corrosion resistance, soluble in hydrofluoric acid and aqua regia, high temperature, metal and nonmetal elements and many elements reaction, generate solid solution of compound.

Natural silicate containing zirconium ZrSiO4 called Zircon (Zircon) or hyacinth stone (hyacinth) widely distributed in nature, with everything from orange to red beautiful color, since the ancient times is considered a gem, Zircon is said to have a word from the Arabic Zarq ū n, cinnabar, say from Persian Zargun, is golden, hyacinth comes from the Greek word "lily", in the Indian Ocean island of Sri Lanka is rich in Zircon. Containing zirconium stones as in ancient times was known in the form of zircon.

1789 germans M.H.K laproth study of zircon, it fused with sodium hydroxide, hydrochloric acid to dissolve the cooling, adding potassium carbonate in aqueous solution, precipitation, filtration and cleaning sediment, sediment and then cook with sulfuric acid, and then filter the silicon oxide, check in the filtrate of calcium, magnesium, aluminum oxide, has not been found, after adding potassium carbonate precipitation in aqueous solution, the sediment is not soluble in alkali as alumina, also don't like magnesium oxide and acid, Klaproth think the sediment and previously known oxides is different, is made up of Zirkonerde (zircon, German), soon, French chemist DE Morueau and Vauquelin both confirmed M.H.K laproth analysis is correct, the element Latin name Zirconium, symbol that Zr, Zirconium translated into Chinese.

In 1808, the British H.D avy zirconium compounds using current decomposition, without success, 1824 Swedish J.J.B erzelius first with K2ZrF6 potassium restored with metal zirconium, but is not pure, reactive as: K2ZrF6 + 4 k = Zr + 6 kf, the reaction can also be used Na as reductant, until 1914, when a Dutch metal incandescent lamp factory two researchers Lely and Ham bruger with anhydrous zirconium tetrachloride and excess sodium metal with sheng into the ball out, using the current heated to 500 ℃, the pure metal zirconium.

Completely pure zirconium was in 1925 the Dutch chemist Anton Eduard van Arkel and Jan Hendrik DE Boer, zirconium by four iodide decomposition (ZrI4). Now this kind of metal heated by magnesium zirconium tetrachloride to mass production.

Zirconium easily absorbed hydrogen, nitrogen and oxygen. Zirconium's affinity for oxygen is very strong, 1000 ° C zirconium oxygen dissolved in can make its volume increased significantly.

Zirconium surface is easy to form a layer of oxide film, gloss, so the appearance is similar to steel. Corrosion resistance, but soluble in hydrofluoric acid and aqua regia. High temperature, can react with nonmetallic elements and many metal elements, generate solid solution. Zirconium plasticity is good, is easy to be processed into plate, wire, etc.
 
When heated to a large number of zirconium in absorption of oxygen, hydrogen, nitrogen and other gases can be used as a hydrogen storage material. Corrosion resistance of zirconium is better than titanium, close to niobium, tantalum. Zirconium and hafnium are similar chemical properties, and the symbiotic together of the two metals, and other radioactive substances.
