In conclusion, the preparation of titanium dioxide from factory settings is a testament to the harmonious integration of science and industrial practices. As technology advances and the demand for titanium dioxide grows, manufacturers continue to refine their methods to achieve greater efficiency, quality, and sustainability.
At present, the domestic wet zinc smelting mainly adopts the roasting-leaching-electrowinning production process, and the zinc content in the acid leaching residue is generally 8-15%, some up to 20%, and the sulfur mass fraction is 6-12%, of which sulfuric acid The root mass fraction is 15-30%, mainly in the form of 0^0 4 (in this ammoniatic environment, the leaching rate of sulfate leaching in multiple stages can reach 70%). The zinc in the acid leaching residue is mainly in the form of ZnFe 2 0 4 . In order to recover these zinc, the treatment methods are currently available in the fire method and the wet method. The fire method is the rotary kiln evaporation method (Wilz method) and the fumigating furnace evaporation method. . The wet method has hot acid leaching or high temperature pressure leaching. The fire treatment process is long, the equipment maintenance is large, the investment is high, the working environment is poor, and a large amount of coal or metallurgical coking coal is consumed, which has low efficiency and large environmental pollution. Therefore, it is usually leached by hot acid or high-pressure leaching. These methods still have the disadvantages of: 1 consumption of a large amount of acid, low leaching rate, due to the large amount of calcium sulfate, calcium sulphate and other ultrafine particles to isolate the zinc oxide particles, resulting in Electrolytic zinc enterprises are difficult to leach in acid environment, and the second weak acid leaching is not meaningful because the recovery rate is too low. 2 If leached with strong acid, although ZnFe 2 0 4 is destroyed, the leaching rate is improved, but the iron leaching rate is also high (up to 60%). The pressure of iron removal is large, and more reagents are consumed. 3 High temperature and high pressure equipment is corroded. Serious, complicated equipment investment; 4 high operating costs, poor economic returns. 5 The last slag discharged is acid leaching residue, which brings new pollution to the environment. It has to be cured and landfilled, which not only pollutes the environment, but also wastes resources.

Post time: 25-05-23Barbed wire was used as a barrier to livestock theft, for one thing, because the surface was covered with sharp spikes that made it very difficult to penetrate through the barbed wire. On the other hand, it is because livestock generally have the habit of running into each other, which makes livestock dare not run into each other with the barbed rope, thus saving the user’s use cost.
- Choose a cage with a proper structure, such as a tray under the cage so that the dog can urinate in the cage. It’s also easy for the owner to clean up.
Post time: 15-05-23- In order to adapt to the living habits of different birds, ornamental cages can be roughly divided into two types of bird cages, namely cereal and insectivorous cages. Cereal bird cage with canary cage, yellow bird cage, wenbird cage, bird cage, hydrangea cage, insect-eating bird cage with thrush cage, chin cage, myna cage and so on.
Large roll galvanized wire as a common industrial supplies in daily life, many people will use, but many of them are not standard operation. Cold galvanized wire is one of the many categories of iron wire, widely used, cold galvanized wire is a kind of galvanized iron wire products made of high quality low carbon steel wire processing, after drawing forming, pickling rust removal, high temperature annealing, hot galvanized, cooling and other processes.

Post time: 03-01-23Usually, there are three kinds of metal corrosion: physical corrosion, chemical corrosion, electrochemical corrosion, corrosion in addition to the chemical properties and organizational structure of the metal itself, but also related to the surrounding medium, such as wet environment is easier to rust than dry environment, more impurities than impurities less easy corrosion, high temperature conditions than low temperature conditions easy corrosion. After understanding these, we can effectively prevent the customized corrosion of hexagonal guardrail and extend the service life of the product.
Electric galvanized shaft wire direct selling is in the plating tank through the current unidirectional zinc gradually plated on the metal appearance, the production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust. Compared with hot dip galvanizing, the production cost of electric galvanizing is lower. The difference between cold galvanizing and hot galvanizing: the difference between cold galvanizing and hot galvanizing is that the amount of zinc is different. They can be identified from the color. The color of cold galvanizing is shiny silver white with yellow. Hot dip galvanizing shiny white.
Specific requirements for the safety of galvanized wire production: clean up all tools and other objects that hinder production in the galvanized wire production environment. Operators in the pickling process, pay attention to the action should be careful, not careless, into the pickling tank must be handled lightly, to prevent splashing on the body. When adding acid, the acid must be slowly poured into the water. It is forbidden to pour the water into the acid, so as to prevent the acid from splashing out and hurting people. Do not hurt yourself or others.
