The so-called low-carbon economy refers to an economic model based on low energy consumption, low pollution and low emissions. Its essence is the efficient use of energy and the development of clean energy. In this sense, the "low-carbon economy" and the machine tool as a production tool seem to be irrelevant.
However, when predicting the development of the machine tool industry in 2010, Wu Bolin, executive vice president of the China Machine Tool Industry Association, pointed out that “there are several unfavorable factors in the development of the machine tool industry this year. The low-carbon economy will also bring some constraints to the machine tool industry. In particular, it will affect the demand of medium and low-end machine tools." So, what impact does the low-carbon economy have on the machine tool industry?
With the release of the "Opinions on Accelerating the Development of China's Equipment Manufacturing Industry", the equipment manufacturing industry has developed rapidly in recent years. In 2008, the total output value of China's equipment manufacturing industry reached US$2016 billion, slightly higher than US$198 billion, far more than Japan's US$1.5 trillion, and Germany's US$132.51 billion. At the beginning of this century, the total output value was still fourth. China’s position has become the world’s number one in total output.
There are hidden concerns behind these exciting data. Taking the more representative CNC machine tool industry in the equipment manufacturing industry as an example, the CNC machine tool industry is the fastest growing industry in the equipment manufacturing industry in recent years. It has been 70% dependent on foreign imports and has been reduced to less than 40%. Among the less than 40% of imported components, they are basically high-end products. This shows that China's equipment manufacturing industry is only pursuing the scale of development in an extensive manner, ignoring the ability of independent innovation and international competitiveness. Low levels of repetitive development have resulted in overcapacity.
The "low carbon" in life is easy to understand. It is nothing more than reducing exhaust emissions and saving electricity. How to achieve "low carbon" in industrial production? This requires not only the innovation of energy utilization technology and emission reduction technology, but also the content of industrial restructuring, institutional innovation and the fundamental transformation of human survival and development concepts. The so-called adjustment of industrial structure is to make the part of overcapacity Slimming." Wu Bolin said that the low-carbon economy brings some constraints to the machine tool industry, which means that the machine tool industry will adjust its overcapacity, and the demand for low-end machine tools will be further narrowed. Big to strong is beneficial.
Although the equipment manufacturing industry itself has a small proportion of energy consumption and resource consumption, its products are “large households†in energy consumption. Therefore, in addition to adjusting the overcapacity in its industrial structure, the machine tool industry, which is the “master machine†of the equipment manufacturing industry, should also undertake the management and recycling equipment that provides low-energy and environmentally-friendly products, provides comprehensive utilization of resources and environmental protection. And advanced production and processing technology to improve the efficiency of machinery manufacturing.
"Low-carbon economy and energy-saving emission reduction have led to the transformation of the development mode of equipment manufacturing industry, from the extensive pursuit of scale development to the development of independent innovation and international competitiveness, as the '12th Five-Year' equipment manufacturing The transformation of the industry's development direction and the breakthrough of strategy." Qu Xianming, the vice president of the former Institute of Mechanical Science and the executive director of the China Mechanical Engineering Society, once said.
As a production tool, the machine tool products turn to the production mode of the equipment manufacturing industry. The significance of change is unquestionable. At the same time, to improve the ability of independent innovation and contribute to the development of low-carbon economy and energy conservation and emission reduction, the machine tool industry is duty-bound.
In recent years, smart dimming glass has been widely used in home partitions, hotel bathroom partitions, office partitions and other scenarios. The glass itself has all the characteristics of safety glass, but also has the control of glass transparent or not privacy protection function. EC dimming glass has a slow response speed, which may be as long as several minutes. PDLC has very limited thermal insulation effect. Increasing the thermal insulation effect can add a layer of low-E glass, while SPD and EC technologies have good thermal insulation effect.Due to the relatively high operating voltage, the application scenarios are relatively limited due to the consideration of security risks, and are relatively rare in China. PDLC has two basic states: transparent and atomized. Even if glass atomized, a lot of light will pass through, that is, transparent but opaque. PDLC can also create transformable transparent or atomized graphic effects on glass, with good design and expansion properties. EC and SPD can continuously adjust the rate of light passing between transparent and colored states, but cannot design graphic effects.
