Zinc oxide is an oxide of zinc. Insoluble in water, soluble in acids and strong bases. Zinc oxide is a commonly used chemical additive, which is widely used in the production of plastics, silicate products, synthetic rubber, lubricating oils, paints and coatings, ointments, adhesives, food, batteries, flame retardants and other products.
Zinc oxide has large energy band gap and exciton binding energy, high transparency, and excellent luminous performance at room temperature, and is used in liquid crystal displays, thin-film transistors, light-emitting diodes and other products in the semiconductor field. In addition, microparticle zinc oxide as a nanomaterial has also begun to play a role in related fields.

The raw material for indirect zinc oxide is zinc ingots or zinc slag. The raw material is converted into zinc vapor at a high temperature of 1000 °C in a graphite crucible, which is then oxidized by the air that is blown in to produce zinc oxide, and the zinc oxide particles are collected after cooling the tubes. The zinc oxide particles produced by the indirect method are about microns in diameter and in purity.
In terms of total production, the indirect method is the most important method for producing zinc oxide. The heavy metal content of zinc ingots or zinc slag directly affects the heavy metal impurity content of the product, and the product with low heavy metal content.

Anonymous users2024-02-01There are two preparation methods for zinc oxide, which are direct method and indirect method.
The direct method is to heat the zinc ore at a high temperature to oxidize it to produce zinc oxide, and then purify it by physical or chemical methods to obtain zinc oxide products. The zinc oxide prepared by the direct method is of high quality, but the preparation cost is high.
In the indirect method, the zinc ore is smelted to obtain crude zinc, and then the crude zinc is heated and evaporated to produce zinc oxide. Its preparation cost is lower, but its quality and purity are not as good as those prepared by direct zinc oxide. Shouzi Shed.
Therefore, for the selection of preparation methods for zinc oxide, it is generally necessary to consider the cost and quality factors. If high quality and high purity zinc oxide is required, and the cost is affordable, the registry recommends the direct method of preparing zinc oxide; If the cost requirement is low, the indirect method can be used to prepare zinc oxide.

Anonymous users2024-01-30Direct zinc oxide uses various zinc-containing minerals or sundries as raw materials;
The raw material of indirect zinc oxide is metal zinc ingots or zinc slag obtained by smelting.
Direct zinc oxide uses various zinc-containing minerals or sundries as raw materials; When zinc oxide is heated and reacted with coke, it is reduced to metallic zinc and steamed, and at the same time, it is oxidized to zinc oxide by oxygen in the air to remove most of the impurities. The zinc oxide particles obtained by the direct method are coarse, and the purity of the product is between 75%.
The raw material of indirect zinc oxide is metal zinc ingots or zinc slag obtained by smelting. Zinc is converted to zinc vapor at a high temperature of 1000 °C in a graphite crucible, which is then oxidized by the air that is blown in to produce zinc oxide, and zinc oxide particles are collected after cooling the tubes. The indirect method was popularized in 1844 by the French scientist Leclaire, so it is also known as the French law.
The process technology of indirect production of zinc oxide is simple, and the cost is greatly affected by raw materials. The zinc oxide particles produced by the indirect method are about microns in diameter and in purity. In terms of total production, the indirect method is the most important method for producing zinc oxide.
Direct zinc oxide is generally used in the ceramic, glaze, frit, glass, and pigment industries.
Indirect zinc oxide: It can be used in rubber, varistor, paint, phosphating liquid, film, thermal conductive materials and other industries. The heavy metal content of zinc ingots or zinc slag directly affects the heavy metal impurity content of the product, and products with low heavy metal content can also be used in livestock feed, medicine, health care and other industries.

Anonymous users2024-01-27Brief introduction of direct zinc oxide: it is a mixture of low-level zinc-containing material and pulverized coal in the volatilization kiln, so that the zinc is volatilized into zinc vapor and then drawn out of the kiln body through the exhaust fan.
Prepared by oxidation-cooling-dust collection. Direct zinc oxide is also known as "raw zinc" in the ceramic glaze industry.
Brief introduction of calcined zinc oxide: In order to improve the physical properties of direct zinc oxide (raw zinc) used in ceramic glazes and the influence of related chemical components, calcined zinc oxide is obtained after calcination by high-temperature processing. By the Institute of Mining and Metallurgy.

The crystalline structure of zinc oxide calcined by the standard heating firing curve is completely transformed, and the specific gravity will increase to about that. The use of calcined zinc oxide in porcelain glaze solves the shrinkage defect of glaze well, which can reduce the firing shrinkage of porcelain glaze, no bald glaze, no bubbles, no pinholes, and can improve the performance of glaze slurry, no thixotropy, good fluidity. Calcined zinc oxide has excellent performance and excellent quality, which is extremely suitable for ceramics and sanitary ware industries.
Business couch, in fact, business couch is a long history, business couch, the ancients said, there were once two towers, so named the twin towers, later, because the people littered in the tower and even urinated, so the fairy Tie Guan Li who took care of the two towers could not stand it, so he moved the two towers to Suzhou, when someone was still installing the best two windows for the tower, and then this person followed to Suzhou, and sure enough, he found that the tower there was just missing the two windows, so it was concluded that the two towers in Suzhou were the twin towers of the business couch. There are also ancients who said that the business couch was originally a place for merchants to pass through here and stay and rest, so it was named the business couch. Nowadays, the business couch is not only a clothing economic city, but also a lot of our traditional culture and art reserves, the business couch is also a good place for people to travel leisurely, because the people of the business couch are enthusiastic, the wind of the business couch is fragrant, the humanities of the business couch are ancient, and the transportation of the business couch is convenient. >>>More

White pollution is a unique environmental pollution in China's cities, a large number of discarded plastic products can be seen everywhere in various public places, they come from nature, made by human beings, and are not easy to be absorbed by nature when they are ultimately attributed to nature, thus affecting the ecological environment of nature. From the perspective of resource conservation, because plastic products are mainly facing depleted petroleum resources, they should be as much as possible, but because the production cost of re-production at this stage is much higher than the direct production cost, it is difficult to do so under the current market economy conditions. In the face of the increasingly serious problem of white pollution, people hope to find a plastic substitute that can replace the current plastic performance, and does not cause white pollution, degradable plastic came into being, this new functional plastic, which is characterized by a certain service life after being discarded, under specific environmental conditions, due to its chemical structure changes significantly, causing some performance loss and appearance changes and degradation, harmless or less harmful to the natural environment. >>>More
The thickness of the fuse is placed according to the load of electricity and the wire diameter of the wire in the circuit, and can not be thickened casually, if it is thickened, once the load increases (if the wire diameter is small) or the circuit fault fuse can not be blown in time, which may cause electrical fire. It is necessary to replace the wire and meter before replacing the fuse (** switch is generally used now). Your analysis of fuse burning there makes sense, it's hard to say about stealing electricity, you have to have evidence. >>>More
