Last week, the current prices of steel products all rose sharply. The State Council launched an investigation into the headwind violations and violations of individual enterprises in the steel industry's capacity reduction work, and the domestic property market ushered in a new round of regulation and control. The latest research report issued by Nishimoto Shinkansen pointed out that the recent theme of steel capacity reduction and environmental governance has once again heated up and fermented. The supply of the domestic steel market is expected to decline further. The current hot steel market may have a boosting effect again. It is expected that the short-term domestic steel prices The rebar inventory in 35 major markets nationwide will still be 3.951 million tons, an increase of 77,000 tons, an increase of 1.99%; the stock of wire rod is 868,000 tons, an increase of 19,000 tons, an increase of 2.24%. From the perspective of the total inventory of the five varieties of wire rod, rebar, hot-rolled coil, cold-rolled coil, and plate in the country, the total national inventory is 8.55 million tons, an increase of 69,000 tons from the previous week, an increase of 0.81 %. Qiu Yuecheng, a senior researcher at Nishimoto Shinkansen, said that national steel market inventories ended the six-week-old downward trend and turned to rise. The stocks that rose mainly were construction steel, and plate stocks were still on a downward trend. At present, construction sites in the Northeast region have basically been shut down. The Beijing-Jinji region of China has issued a wide range of environmental protection measures. Many construction sites have been shut down for rectification. Domestic steel market demand has weakened, and inventories have turned from falling to rising. The Executive Meeting of the State Council held on November 23 pointed out that all localities and central enterprises should be guided to carry out inspection and acceptance of the task of eliminating excess and backward production capacity this year in strict accordance with the standards. . In particular, backward production capacity must be resolutely eliminated, and no equivalent replacements are allowed. At the same time, the news shows that in response to the discovery of Hebei Anfeng Iron and Steel Co., Ltd.'s failure to first build and approve the construction of the iron and steel project, the production and sale of "ground strip steel" in Jiangsu Xinyi Small Steel Plant, and other laws that violate the law and regulations and seriously interfere with normal production and operation orders The State Council decided to send an investigation team to be severely investigated and dealt with, severely held accountable and accountable to the relevant responsible persons, and publicly notified the investigation and processing results. According to the deployment of the State Council, the two investigation teams of the State Council have gone to Hebei and Jiangsu to investigate the violations of laws and regulations of individual enterprises in the steel industry's capacity reduction work. Relevant agency sources revealed that some steel enterprises in Hebei and Jiangsu have voluntarily stopped production to cooperate with the investigation, especially in the middle frequency furnace production enterprises in Jiangsu area. With the deepening of the investigation in the later period, it is expected that more illegal enterprises will stop production, which will have a certain impact on the overall market supply. In addition, the Ministry of Environmental Protection recently sent a supervision team to conduct special inspections on the emergency response of Taiyuan, Linfen City, Shanxi Province, and Tangshan City, Hebei Province. During the inspection, the inspection team of the Ministry of Environmental Protection found that in some cities, the emergency response measures for heavily polluted weather are not in place. Qiu Yuecheng pointed out that the environmental protection in the later stage will continue to increase, and the production of steel companies will also be inhibited. Re-heating and fermenting the subject of production capacity reduction and environmental protection will be significantly beneficial to the steel market. With the continuous tightening of the housing market regulation and control policy, the hotspot cities have recently shown clear signs of cooling. If the cooling of the property market leads to a decline in the growth rate of real estate investment, it will have an adverse impact on the domestic steel market demand. Nishimoto Shinkansen believes that since the housing market cooled in October, there are obvious signs of accelerated capital inflows in the field of commodities, pushing up the prices of various commodities in turn, and the market has a strong atmosphere. Therefore, although the domestic steel market is facing pressure to weaken demand in December, domestic steel prices may still have the momentum to rise further due to factors such as high costs, reduced steel mill output, and sufficient funds.

1. After the aluminum silicate masonry is finished, stop the surface finishing once. The uneven parts must be smoothed with a pressing plate.

(Summary description)Ceramic fiberboard is suitable for high-temperature fields that require steel strength, but sometimes there will be some yellowing phenomenon. This actually has a certain impact on our use, not only affects the aesthetics, but also uses it. The effect will be somewhat affected, so what are the reasons for its yellowing? The main reasons for everyone are as follows. Ceramic fiberboard is suitable for high-temperature fields that require steel strength, but sometimes there will be some yellowing phenomenon. This actually has a certain impact on our use, not only affects the aesthetics, but also uses it. The effect will be somewhat affected, so what are the reasons for its yellowing? The main reasons for everyone are as follows. 1. The yellowing of ceramic fiberboard is mainly caused by the crosslinking agent and tackifier in the neutral rubber, because these two raw materials have "amine groups", and the amine groups are very easy to cause yellowing, and many imported famous brands The glass glue also turns yellow. 2. If the outer neutral transparent glue is used together with the acid glass glue, it may cause the neutral glue to turn yellow after curing. 3. It may be caused by the long storage time of the glue or the glue reacts with the substrate. The reason why the ceramic fiber board turns yellow may be caused by the raw materials in the neutral glue, or it may be caused by improper use and storage, but in the final analysis, no matter what, we need good maintenance and timely treatment.

The word "aerogel" has been increasing in frequency in recent years, and people's understanding of aerogels is also deepening. From knowing nothing about it to gradually realizing its superiority, especially after emphasizing the role of new materials strategy in the 13th Five-Year Plan, aerogel has become the focus of attention in advanced new materials. At present, China's research work on aerogels is mainly concentrated in the Boer Institute of Solid Physics, Tongji University, National University of Defense Technology, Tsinghua University, Zhejiang University, Harbin Institute of Technology, etc. At the same time, the professionalism of Chinese colleges and universities in the field of aerogel research and the ability of domestic companies to explore the technology of reducing aerogel manufacturing costs have been the continuously strengthened, and they have begun to advance to the world's advanced level and enter the world's advanced ranks. Tongji University helps research and development in the field of aerogels In 1931, Kistler of Stanford University prepared aerogel by hydrolyzing water glass, but because of the high production cost, it has not received widespread attention. In the 1980s, some physicists in Europe began to study this new material. In 1985, the Institute of Physics of the University of Wurzburg organized the first "Aerogel International Symposium". In the early 1990s, the United States resumed research on the aerogels. Tongji University also began research on aerogels in the 1990s, which can be said to be the earliest batch of research institutes in China to study aerogels. Aerogel is composed of more than 90% air and less than 10% solids. Aerogel is the most dense in the world One of the small solids, the density is only 3 kg per cubic meter. The special nanopores and network structure of aerogels exhibit many excellent physical and chemical properties and functions. Ni Xingyuan said, "We at the Institute of Solid Physics of Tongji University first started to study the application of the physical properties of aerogels. At present, most of the researches on the functions of aerogels are based on physical functions. At present, Tongji University Research on the function of aerogels has focused on thermal, optical, electrical, acoustic, and mechanics (such as explosion-proof, impact resistance), etc., and has also carried out some research on chemical adsorption. "In terms of materials, we The research is relatively extensive. We have studied inorganic aerogels, organic aerogels and composite aerogels. In addition to the most common silicon aerogels, there are carbon-based, sulfur-based, metal oxide-based, metal-based, etc. Wait, Tongji University is involved in most of these areas. " In the earliest applications, aerogel was widely used in the aerospace and military fields, because of some characteristics of aerogel, it has become an irreplaceable material in aerospace exploration, the Russian "Peace" space station and the US "Mars pathfinder" The detectors are used for insulation. At present, in addition to the aerospace field, aerogel can also be widely used in many fields such as military industry, petrochemical, power, metallurgy, construction, clothing, etc., especially as an important substitute for traditional thermal insulation materials. Insulation is currently a hot spot for aerogel application development. When the front of the aerogel is subjected to a flame spray of more than 1000 degrees Celsius, the back can still be touched by hand. This is due to the very low thermal conductivity and refractive index of aerogels, and its insulation capacity is dozens of times better than the best glass fibers. The promotion of aerogel should change the understanding and reduce the cost At present, many companies in China are engaged in the research and development of aerogels, but the application of aerogels in the field of building materials has not been widely promoted. The main reason is that the price of aerogel felts is relatively high compared to existing insulation materials. Therefore, if there are no special requirements in the construction field, building designers and developers will generally not consider the use of aerogel felts as thermal insulation materials. Compared with other thermal insulation materials, aerogel has comprehensive advantages that other materials cannot match. "Compared with other traditional thermal insulation materials, aerogel felt has lower thermal conductivity, better thermal insulation performance than other materials, and under the same environmental conditions, the better the thermal insulation performance, the more obvious the reduction in thermal insulation or insulation Thermal energy consumption; from the perspective of building structure, aerogel felt will be thinner and lighter, which can expand a large space in the area of the building. At the same time, due to the lighter product, it can reduce the building Concerns about load-bearing capacity. At the same time, aerogel composite products also have their own excellent performance in sound insulation, fire prevention, moisture resistance and other aspects. Overall, the cost performance of aerogel composite products is much higher than other insulation materials. Ni Xingyuan pointed out that in the design and development of buildings, people do not have enough knowledge about aerogel composite products. The next step is to strengthen their promotion and promotion in the field of building materials. Of course, from the perspective of aerogel production enterprises, it is necessary to consider further reducing their production costs, to reduce the raw material cost of aerogel production and adjust the production technology of composite aerogel to tap potential. In addition, if the production of aerogel products is of considerable scale, the production cost will be further reduced. After people's awareness is strengthened and product costs are reduced, aerogels will be used in the construction field on a larger scale.

Today, the editor briefly talked to you about the "Enpu" ceramic fiber board, a very widely used type of equipment-kiln. Classification of kilns According to the variety of calcined materials, it can be divided into ceramic kiln, cement kiln, glass kiln, enamel kiln, etc. Can be divided into flame kiln and electric kiln according to pyrogen. According to the condition of the heat source facing the blank, it can be divided into open flame kiln, muffle kiln and semi-muffle kiln. According to the green body delivery vehicles, it can be divided into kiln car kiln, push plate kiln, roller bottom kiln (roller kiln), conveyor belt kiln, walking beam kiln and air cushion kiln. Can be divided into single-channel kiln, double-channel kiln and multi-channel kiln according to the number of channels. The following are the most common types of kilns: The inside of the furnace roughly includes the following and parts: Ceramic fiberboard insulation layer, refractory brick layer, kiln frame and metal shell. Whether the kiln structure is reasonable and the material is reliable is directly related to the quality of the product, the output and the level of energy consumption. For a long time, "Enpu" ceramic fiber board has been widely used in various kilns and has established a good Word of mouth.
