What is Titanium Dioxide Ema?

Titanium Dioxide Ema takes place naturally in titanium ores such as titanium and rutile. Its molecular structure provides it high brightness as well as opacity, but initially it must be chemically extracted and detoxified. Greater than 60 years back, DuPont invented the chlorination approach Titanium Dioxide Ema manufacturing procedure. Compared with the old sulfuric acid technique, it can decrease environmental emissions and also power intake while making premium pigment products. It has become the favored modern technology worldwide.Titanium Dioxide Ema (or TiO2) is one of the most extensively utilized white pigment in the sector.

Titanium Dioxide Ema Production Method

There are two production methods of titanium dioxide: sulfuric acid method and chlorination method. The sulfuric acid method is to acidify ilmenite into a massive solid phase by concentrated sulfuric acid, and then leaching with acidic water to obtain titanium liquid. Decompose into metatitanic acid. Titanium dioxide is obtained by calcining and pulverizing after washing with water. Reaction equation:

H2SO4+TiO2→TiOSO4+H2OTi(SO4)2+H2O→TiOSO4+H2SO4TiOSO4+H2O→H2TiO3↓+H2SO4H2TiO3·SO3→TiO2+H2O+SO3↑The chlorination method is to mix the crushed rutile or high titanium slag with coke, It reacts with chlorine gas in a fluidized bed chlorination furnace to generate titanium tetrachloride, which is purified and oxidized by adding a crystal conversion agent in high turbidity to generate titanium dioxide, which is then washed with water, dried and pulverized. Reaction equation:

2TiO2+3C+4Cl2→2TiCl4+2CO↑+CO2↑TiCl4(vapor)+O2(gas)→TiO2(solid)+2Cl2(vapor) The operation method is as follows.

Inside a conical acid hydrolysis tank lined with two layers of tiles. According to the ratio of mineral acid ratio of 1:1.5~1:1.7 (mass ratio, sulfuric acid is calculated as 100%), make the pre-adjusted process concentration of 88%-90% sulfuric acid and pre-pulverize to 325 mesh and mix 0.2% antimony oxide The dried ilmenite powder is subjected to acidolysis reaction. The acid hydrolysis reaction can only take place when the reactants are preheated to above 90°C. Under the stirring of compressed air, with the progress of the reaction, the heat of reaction increases, and the temperature gradually rises to 180-200 °C, and a violent reaction occurs. Afterwards, a porous solid-phase acid hydrolysis reaction product is formed. After cooling, leaching is carried out in a precipitation tank at 55-65 °C. A flocculant is added to the obtained leachate, and the unseparated matter and mechanical impurities suspended in the leachate are separated by sedimentation. The obtained leachate mainly contains titanium sulfate, but also contains many divalent and trivalent ferric sulfates. The ferric iron is reduced by adding iron filings, and then frozen to 3-5°C. The ferrous sulfate can be crystallized out by a frozen brine refrigeration device or a vacuum adiabatic evaporative refrigeration device, the by-product ferrous sulfate is removed by filtration, and the pure titanium liquid is concentrated to 190-210gTiO2/L solution by vacuum evaporation, and sent to hydrolysis under stirring Reactor, adding pre-specialized seed crystals in the seed crystal tank for hydrolysis to generate hydrated Titanium Dioxide Ema (commonly known as metatitanic acid). There are two methods to realize the hydrolysis process in industry: normal pressure and pressurization, and the temperature is different. There are also many methods for making seed crystals, which vary with product requirements and manufacturers. The metatitanic acid generated by hydrolysis is repeatedly washed with a leaf filter to remove soluble iron salts, and then sent to a rotary furnace for calcination at 800-850 °C. Before calcination, salts should be added to the salt treatment tank for salt treatment. The purpose of the salt treatment is to reduce the calcination temperature and promote the transformation of the crystal form, and to improve the grinding wettability of the pigment. The calcined Titanium Dioxide Ema does not yet have pigment properties and requires post-processing. The post-processing is to dry-pulverize the calcined Titanium Dioxide Ema with a Raymond mill or a universal pulverizer, and then use a spray dryer (or a belt dryer, boiling Fluidized dryer, drying room, etc.) drying, and then superfine pulverization with a jet mill to ensure that the particle size of the product is below 1 μm.

Rutile ore containing 90% to 95% rutile is crushed, dried and strictly controlled in particle size (or high titanium slag) and continuously enters into the fluidized bed chlorination furnace with petroleum coke, and the chlorination reaction is carried out by passing chlorine gas at a temperature of 900 to 1000 ℃. Since the raw materials contain oxide impurities such as iron, manganese, silicon, zirconium, etc., the titanium tetrachloride obtained by chlorination is cooled to 400 ° C and subjected to rectification after preliminary purification to obtain refined tetrachlorotetratitanium. Refined titanium tetrachloride is vaporized at 150-200 °C and high-purity aluminum trichloride is added as a crystal transformation agent, and then preheated and heated to about 1000 °C before entering the oxidation furnace. The oxygen used in the oxidation furnace is also preheated. Oxidation temperature 1300 ~ 1500 ℃. The solid Titanium Dioxide Ema produced by gas phase oxidation has begun to have pigment properties. After post-processing, the pigment Titanium Dioxide Ema can be obtained. The post-treatment method is the same as the sulfuric acid method.

Analysis of Titanium Dioxide Ema Content

Properly weigh about 300mg of the sample pre-dried at 105 ° C for 3h, move it into a 250ml beaker, add 20ml of sulfuric acid as well as 7-8g of ammonium sulfate, and blend well. Warm on a warmer till sulfuric acid fumes appear, and also remain to heat on a strong fire till the sample liquifies, or it is apparent that the insoluble deposit is siliceous. Amazing, weaken thoroughly with 100ml of water and also mix well. Carefully heat to boiling with stirring, as well as filter after the insolubles have actually settled. The whole deposit was transferred to the filter and also washed extensively with chilly dilute sulfuric acid test option (TS-241). The filtrate and launderings were watered down with water to 200 ml, as well as concerning 10 ml of concentrated ammonia examination solution (TS-14) was carefully included in decrease the acid focus to regarding 5% (by volume of sulfuric acid). Prepare a zinc amalgam column in a 25cm Jones decrease tube, position a glass wool swab at the bottom of television, and fill the narrow part of the reduction tube with zinc amalgam. The prep work approach is as follows: add 20-30 mesh zinc powder to 2% mercury chloride In the solution, regarding 100ml of service is made use of for every 100g of zinc. After around 10 minutes, the option was decanted from the zinc, as well as the zinc was washed with water by decanting. Relocate the zinc amalgam into the decrease tube, and afterwards wash the column with 100ml of water down sulfuric acid test remedy (TS-241) each time until 100ml of the eluate can not make one decline of 0.1 mol/L potassium permanganate solution fade.

Place 50ml of ferric ammonium sulfate test solution (TS-99) in a 500ml suction filter container, add 0.1 mol/L potassium permanganate to pink, as well as continue for 5min. Link the Jones reduction tube including the zinc amalgam column to the bottle neck of suction filtration, and also make 50ml of thin down sulfuric acid test service go through the tube at a rate of concerning 30mL/min. After that pass the ready titanium service with the column at the very same rate, and afterwards pass through 100 ml of weaken sulfuric acid test option and 100 ml of water. During this procedure, keep the service or water completed the tube constantly over the top liquid degree of the zinc amalgam column. Gradually remove suction, purge the outlet tube and the side wall of the receiver, as well as instantly titrate with 0.1 mol/L potassium permanganate. At the same time, execute a blank test, that is, change the sample option with 200ml of 5% weaken sulfuric acid, as well as make necessary modifications. Each 0.1 mol/L potassium permanganate is equivalent to Titanium Dioxide Ema (TiO2) 7.990 mg.
