Silane, that is, the compound of silicon
and hydrogen, is a general term for a series of compounds, including silane
(SiH4), ethyl silane (Si2H6) and some more advanced silicon hydrogen-derived
compounds, the general formula is SinH2n+2 or hydrogen is substituted by other
functional groups after the derivative, of which silane is the most common,
sometimes referred to as silane.
In 1857, the German chemist H Buff discovered silanes, and for the next 100 years or so silanes were only a few researchers studying in the laboratory, without any use. With the rise of semiconductor technology in the 1950s, people began to consider the specialties of silanes, and silanes began to be used in the electronics industry. In the 1980s, the application of silanes underwent major changes. With the advent of a series of new technologies or the success of the development of new products using silanes, the use of silanes has increased dramatically. Thousands of tons of silanes are processed into ultrapure semiconductor silicon in factories every year, and hundreds of tons of gas are used to make a wide variety of new materials and devices. Considering that most devices in these applications consume only milligrams or even micrograms of gas per device, and the thickness of the film made of silane is in the order of microns, it can be seen that the above silane amount is not a small number. In the 1990s, a larger number of new functional devices came out, among which ultra-high-speed, large-capacity computer chips, high-definition flat panel displays, high-efficiency and low-cost solar cells, high-performance ceramic engine parts, sensors with various specific functions, etc. have been developed on a large scale, and more updated devices are still emerging, and these devices are using silanes.

The difficult process of the development of concrete pump trucks in China
China introduced the Japanese technology from 1982 and started to mass-produce the pump truck. At the beginning, it basically introduced the assembly of parts, or the combination of technology and trade to introduce the production mode and the introduction of some parts. The production volume is not large. . After more than 20 years of development, the design level and manufacturing capacity of the pump truck have been greatly improved. At present, there are more than ten production and manufacturing enterprises in China, and the production capacity is mainly concentrated in Futian Heavy Machinery, Sany Heavy Industry, Zoomlion, Shanghai Putzmeister and other enterprises. The output accounts for more than 90% of the whole industry. . Before 1999, the annual sales volume of pump trucks nationwide was only about 50 vehicles. After 2000, the production and sales volume of pump trucks increased rapidly. In 2001, the output was 248. In 2002, the output reached 500 (there were 70 concrete pump trucks imported in the same year). In 2003, the sales volume was nearly 1,000. The concrete pump trucks currently produced in China are mainly at 37 meters and 45 meters.
The manufacturing cost of the pump truck is mainly composed of five parts—the chassis, the hydraulic system, the boom, the pumping system and the control system. The chassis accounts for the largest proportion. At present, the chassis selected for the pump trucks are all imported, mainly concentrated on several chassis such as Volvo, ISUZU and Mercedes-Benz. However, the introduction of high-cost foreign chassis makes the cost of pumping trucks increase invisibly, which makes it more difficult for domestic procurement users to purchase pump trucks. The most critical requirements for the pump to the chassis are the reliability of the power and the economy of the fuel. Futian Heavy Machinery seized this point and used the advantage of its own manufacturing chassis to introduce Cummins, the first brand engine of construction machinery, to develop a special chassis that meets the actual value of the pump truck.
The performance of the fourth generation concrete pump truck is second to none
With the rapid development of domestic commodity concrete industry and construction machinery leasing business, the expansion of construction scale and scope and the development of the western region have promoted the rapid development of construction machinery and related concrete conveying machinery, providing a large market space for concrete pump trucks. .
The “fourth generation concrete pump truck†launched by Foton Heavy Machinery is of great significance. It is developed and manufactured by Futian Heavy Machinery using value engineering principles. It has outstanding cost performance and localization advantages. It can be called “China Commodity Concrete Machinery onceâ€. The industry revolution has completely realized the value transfer to customers. Due to its independent intellectual property rights, it is a major breakthrough for China's domestic concrete pump truck manufacturers in this field. The timely launch of this product has well curbed many foreign concrete machinery. The speed of development of manufacturers in the Chinese market is bound to cause vibration and transformation of the concrete machinery industry. At present, the launch of the pump has attracted close attention and favor from domestic users.
Over the years, due to the influence and constraints of factors such as technology and cost, many domestic concrete machinery products have been unable to meet the actual needs in the increasingly demanding domestic construction market. To a certain extent, the reliability and price of the products determine the purchasing behavior of people. The “fourth generation concrete pump truck†launched by Futian Heavy Machinery is another wonderful work of the national industry. It will be a strong shock to the manufacturers who have used imported equipment in the past. The pump represents the nationalization of the concrete machinery industry. Direction of development.
The launch of the pump truck is a concrete manifestation of the strategic development of Futian Heavy Machinery, and is the result of the company's long-standing adherence to the law of market development. Futian Heavy Machinery has emerged in the field of commercial concrete machinery, and it will also indicate that in the future concrete machinery industry, the fourth-generation pump trucks manufactured by Foton Heavy Machinery will be the leader. Since the pump was put into Suzhou, it has experienced three days and three nights of “destructive†tests before and after the competition with the domestic counterparts. At present, it has been hitting Wanfang with no faults. The innate advantages of the products have created Futian Heavy Machinery.
In 2005, Futian Automobile brand value was 11.932 billion yuan, once again confirming Futian Automobile's position as the first brand of China's commercial vehicles. Foton Heavy Machinery took full advantage of this advantage and entered the special industry with high-end positioning to enter the special industry to lead the technology. Excellent quality and perfect service have entered the four fields of urban construction, urban logistics, urban security and urban management. They have mixer trucks, pump trucks, tow pumps, truck pumps, truck cranes, semi-trailers, dump trucks and oil tanks. Multiple series of cars. Due to the adoption of international advanced equipment and process technology, the company's comprehensive competitiveness is at the leading level in China, forming an annual production of 15,000 special vehicles such as concrete mixer trucks, pump trucks, semi-trailers, dump trucks and tank trucks. The production capacity of the concrete mixer truck in 2005 has jumped to the second place in the industry.
Since the establishment of Futian Heavy Machinery, there have been frequent appearances. On May 29, 2005, Futian Heavy Machinery Co., Ltd.'s first complete commercial concrete mixing plant was officially put into use in Jiaqiang Concrete Mixing Co., Ltd., Zhangjiakou City, Hebei Province, which marked the official start of Futian Heavy Machinery to enter the commercial concrete industry. pace of.
At present, Futian brand resources, superior product resources, and service network resources have formed the strength of Futian Heavy Machinery in the special-purpose vehicle industry market. This development momentum is also better for Futian Heavy Machinery to promote the use of value engineering principles to develop cost-effective "fourth. The generation of concrete pump trucks has laid a good development opportunity.
China's concrete machinery market in progress
At present, China's concrete machinery and international advanced technology maintain a synchronous development level, and are developing towards intelligence. The self-detection, self-protection, self-adjustment of concrete machinery and equipment, as well as the wide application of various sensing technologies, constant power control technology and GPS positioning technology, make the gap between domestic and international products in terms of product quality and international has become very small. The reliability and adaptability have been greatly improved.
Of course, because China's machining equipment, manufacturing materials and enterprise management still have a certain distance from the international advanced level, this also makes China's concrete machinery manufacturing and the world famous brand products also have some gaps, such as the pump truck produced in China. The height of the frame has not yet reached the height of 62 meters in Putzmeister, Germany. The engines and hydraulic components in China's high-end products have to rely on international support.
In the future, with the further development of China's commercial concrete machinery, there is still a lot of work in developing green manufacturing, research and development of energy-saving products, environmentally friendly products, reducing secondary pollution during construction, remanufacturing of machinery and equipment, and recycling of resources. Waiting for China's concrete machinery industry to work hard.
Here, I sincerely hope that the development of concrete machinery in China will be further enhanced.
The reason why silane is widely used in high technology and is becoming more and more important is first of all related to its characteristics, but also related to the special needs of modern high technology. Through thermal decomposition or chemical reaction with other gases, a series of silicon-containing substances such as monocrystalline silicon, polycrystalline silicon, amorphous silicon, metal silicide, silicon nitride, silicon carbide, and silicon Oxide can be prepared from silanes. Silanes enable the highest purity, finest (up to atomic size) control, and the most flexible chemical reactions. Thus, a variety of silicon-containing materials are made into complex and fine structures according to various needs, which is the basic condition required by modern materials and devices with various specific functions.
