Major titanium white powder manufacturer abroad - Kemeiji Company
Branch US-based company (Kerr McGee Corporation) is a natural resource companies, including oil and gas exploration and production, oil refining and sales, far sea drilling, chemical production and coal mining. Its subsidiary, Kemeiji Chemical Co., manufactures and sells industrial chemicals and specialty chemicals as well as forest products.
In 1959, the company formerly known as American potash Chemical Company (American Potash & -ChemicalCorp., Referred to as AP & CC) in cooperation with the British Ruburt industrial company, to develop the chloride process titanium white powder production technology. This technology was successfully developed in the 1960s and is called the AP&CC method. In 1962, the US Potash Chemical Company invested $15 million to build a 25,000 tonne/year chlorinated Titanium Dioxide plant in Hamilton, Miss., using the developed AP&CC technology, and commissioned it in 1965.
The company has developed AP & CC method technology is mature, can be transferred, using the technology to build chlorination of company American Cyanamid Company, SCM company, Ishihara Sangyo Yokkaichi factory and plant in Singapore, India Clara minerals and metals, British Labert Industrial Company. Since the late 1980s and early 1990s, the company has been active in the titanium dioxide business, with its chlorination technology as a share, and a 75,000 tons/year chlorination plant in Saudi Arabia.
In order to solve the problem of the supply of minerals in the chlorination process, the company invested $53 million in the early 1970s and built it in Mobile, Alabama, using the BCA method developed by Benilet (hydrochloric ACID circulation leaching). A 100,000 tons/year artificial rutile factory. It also works with an Australian company (Ti West) to produce rutile titanium dioxide.
In 1998, Kerr McGee merged with Bayer's titanium dioxide factory and Kemira's main titanium dioxide factory. Its annual production capacity increased from 170,000 tons to over 600,000 tons, ranking eighth from the original. Ascended to the third place, the chlorinated rutile titanium dioxide produced by the company was registered under the trademark “Tronox†and the production capacity of the titanium dioxide production plant located in the company.
Sodium Tripolyphosphate, Na5P3O10, Molecular weight 367.86, white powder; Melting point 622 °C. free soluble in water, aqueous solution appears acid. It has got salient chelating capacity to metal ions of Ca and Mg etc. and can soften hard water to make suspension into solution, alkalinity, without causticity. It is an inorganic compound with formula Na5P3O10, is the sodium salt of the polyphosphate penta-anion, which is the conjugate base of triphosphoric acid.Sodium tripolyphosphate is produced by heating stoichiometric mixture of disodium phosphate, Na2HPO4, and monosodium phosphate, NaH2PO4, under carefully controlled conditions.
It has different bulk density, i.e. low density 0.35-0.6g/cm 3 , medium density 0.6-0.8g/cm3 and high density 0.8-1.0g/cm3. This product has two crystalline forms, namely phase I (high temperature phase) and phase II (low temperature phase). The chemical properties of the two phases are the same, and the difference between them lies in the thermostability, hygroscopicity, solubility and hydration heat when dissolving.
It can be used as one of the main auxiliaries for synthetic Detergent, synergist for soap; water softener, tanning agent for leather making, auxiliary for dyeing; As an effective dispersion agent for suspensions of coatings, kaolin, magnesium oxide, calcium carbonate and drilling mud etc.
As an oil contamination resistance agent in paper production; As in foodstuff industry it is used as quality improver in the process of canned food, fruit juice drinks, foodstuffs from milk or soybeans. It may tender the meat in canned ham and soften the skin of horse bean in canned horse bean. It may also serves as a softener or densifier in foodstuff industry.
