At present, the energy saving rate of the general frequency converter is about 20% to 30%, and the maximum may even exceed 50%. Taking the electricity market as an example, in order to improve the atmospheric environment quality, the newly-built thermal power coal-fired generating units have all required simultaneous construction of denitrification projects and dust removal. Technological transformation projects are urgently needed for the transformation of corresponding equipment such as air preheaters and induced draft fans. Looking at China's inverter market, it has maintained a growth rate of 12% to 15% in recent years. Industry insiders expect that the growth rate of the installed capacity of the inverter in the Chinese market is actually around 20%. The potential market space is approximately 120 billion to 180 billion yuan, of which low-voltage inverters account for about 60% of the market share, and the remaining 40% are occupied by medium and high-voltage inverters.
In fact, the expansion of the domestic inverter market has become a catalyst for the rise of local inverter companies. Inventronics, Easy Energy, Anbang, Zhiguang Electric and other domestic inverter manufacturers have begun to occupy more and more market share thanks to their price advantage. Hekang's frequency conversion is dependent on continuous research and development, and it is not easy to capture 13% of the market share in the containment of foreign brands. The pace of localization still needs to be accelerated. After rapid development in recent years, the gap between local inverter brands and foreign well-known brands has gradually shortened.
However, it cannot be denied that the development of China's inverter industry depends on the penetration of foreign brands. The lack of market share has always been the constraint of local inverter brands. According to a power plant denitrification report issued by Chen Qiuquan, supervisor of Hekang Inverter Company, the share of China's inverter market in 2012 was still more than two-thirds of foreign brands such as Siemens, Schneider Electric, ABB, and Dongfang Hitachi. At present, the demand for high-precision and large-scale inverter equipment in the domestic market is still dominated by foreign brands such as Japan, Europe and the United States. The space reserved for domestic-made inverters and the growth time are few.
It is easy to see that the domestic inverter companies must seek breakthroughs in the invasion of foreign brands on the one hand, and on the other hand, they must face the reality that the domestic inverter market needs to expand, and the competition in the inverter market will intensify. Therefore, some enterprises lacking the precipitation of the inverter industry, the establishment of a short time, the small scale of the enterprise, and the shortage of funds will face the risk of being reshuffled. In order to open up the market, some newly-emerged brands, at all costs, shifted the contradiction of market competition to compressing manufacturing costs, lowering prices, and playing a price war. These are not conducive to the sustainable development of the domestic inverter market.
In industry, the amount of Fluorescent Whitening Agent Ob is very large, but there are many ink manufacturers using Fluorescent Whitening Agent OB but do not know what kind of good. I will introduce to you. The fluorescent Whitening Agent OB can be dissolved in an organic solvent, but the solubility is relatively low. When many ink manufacturers dissolve, it is considered that the product of the fluorescent whitening agent OB having good solubility is high in purity, which is also a mistake. Confirmed. The amount of good fluorescent whitening agent OB used in the ink is also very small, as long as it is added to 200 to 300 grams per ton, the high addition amount will affect the color of the product, so that the fluorescent whitening agent OB cannot be completely dissolved. The effect of using a fluorescent whitening agent OB is also good, and it is also recognized by many ink manufacturers, that is, plastic gang.
Generally, in the production process of good water-based ink coatings, the Fluorescent Brightener OB is used. Fluorescent Brightener OB not only increases the whiteness of the ink, but also increases the brightness of the ink. Fluorescent brightener OB-1 improves the grade of the product.
Therefore, it is very important to choose the Optical Brightener . Jinan Forever Chemical has always been adhering to the tenet of [ integrity management, cooperation and win-win", providing each customer with the highest quality optical brightener. And the appearance of color personalization needs.
