With the rapid development of China's cement industry, and the country's high regard for energy conservation and emission reduction, cement grinding aid has become a necessity for cement enterprises. In the 12th five-year development plan of cement industry issued by the ministry of industry and information technology, it is clearly stated that cement grinding agent has a remarkable effect on energy conservation and emission reduction in cement production.
It was first invented in the United States and Japan in the 1930s, when the composition of the grinding agent was mainly rosin ester and butter. Domestic study of cement grinding aid originated in the mid - 1980 - s, due to the development of domestic cement industry is limited, the appearance of grinding aid has not been the industry's high attention and promotion, until the 1990 s, under the guidance of foreign brands in China's firms pioneered the landmark cement grinding aid products.
Shortly after the emergence of these grinding aid companies, sharpening companies have sprung up, even in the form of local businesses. Subsequently, the domestic grinding agent industry entered the stage of vicious competition; It was not until the establishment of the trade association in July 2007 that the grinding agent industry entered a stage of orderly development; Now, with the slowdown of domestic economic growth, cement companies' profits have declined a certain amount, and the grinding aid industry has also been affected. What has changed in the market for grinding AIDS over the last decade? Where is the future development of the grinding aid industry? In this regard, we have compiled the development report of the grinding aid industry for reference by the industry.
1. Overview of the development of grinding AIDS.
1. Birth and survival.
In the mid 1990s, cement grinding aid was valued by the industry, but it was limited by the development level of the cement industry at that time, and there was no major change in the grinding aid enterprises. After entering the 21st century, with the surging of domestic cement industry, the grinding aid industry has also developed rapidly, and in 2006, it reached over 1000.
The emergence of many grinding aid enterprises has led to a mixed situation in the industry of grinding aid. Grinding agent product diversity, vicious competition between enterprises and the production process and time not neat, not only make the effect of grinding aid was supposed to have a big discount, also grinding agent. The development of the industry caused great resistance.
There are many kinds of products, using unscientific hidden trouble. At the beginning of the 21st century, the morphological classification of the grinding aid was liquid and powdery, and from the amount of participation, it was numerous. At that time, as there is no relevant industry standards, related to the quality and technical supervision departments to lax, some unscrupulous add grinding agent, cement enterprises in order to increase the participation of mixed material quantity, reduce the amount of raw material, and reduce the production cost. What's more, some of the mill companies use salt, alkali and urea, which seriously harm the quality and health of the cement.
Vicious competition promotes resistance to quality products. Any new industry appears at the initial stage of the chaotic situation, in this case, also hard to avoid can appear some irresponsible producers, they seize market means no more than two kinds: fake products and low price. The consequences of shoddy products to cement companies are self-evident. The low price of the grinding aid enterprise is also the premise of sacrificing product quality and service. For example, in 2006, more than 5000 national cement size, if there are more than thousand grinding agent enterprises, in addition to cement enterprises without grinding agent, each enterprises average to only five cement grinding agent customers, it is bound to cause grinding aid the vicious competition of the enterprise.
With the fission of the grinding aid enterprise insiders, the grinding aid formula is no secret, the automation equipment is the hard truth. As the initial grinding aid industry did not have access to the threshold, the manufacturers everywhere could be seen, which eventually led to the deterioration of the cement enterprises' attitude towards the grinding agent. With the development of the grinding aid industry, the automation equipment gradually replaced the manual. At this time, due to the lack of timely follow-up by the local grinding aid enterprises, it was not allowed to close down. The development of grinding aid production equipment has effectively purified the grinding aid industry.
When it entered 2007, the grinding aid industry was reduced by a third after nearly a year of market elimination and industry baptism.
2. Brand establishment and value expression period.
In July 2007, approved by the state ministry of civil affairs, China cement association cement grinding aid branch was founded in jinan, shandong, China research and development, production and use of grinding agent has entered the phase of the rapidness, standardization and standardized.
The association was set up two months or so, association issued "the cement grinding aid determination, product quality certification management regulations (draft)" (hereinafter referred to as the "measures"), to explicitly put forward: association and China building materials inspection certification center is responsible for the cement grinding aid product quality determination, authentication management work, on the basis of CTC/TVS - OP05 the cement grinding aid product certification implementation rules, the regular of grinding aid enterprise product certification, and the production process control, quality management system review and checking. In addition, the product identification, certification conditions and procedures of the grinding aid enterprise are specified in detail. At the same time, it also gives a detailed description of the supervision of the grinding aid enterprise.
By the end of 2008, China building materials science research institute of cement and new building materials research institute science to develop the cement grinding aid, get approved by the national standardization committee. After more than three years of efforts, the national standard "the cement grinding aid" (GB/T26748-2011) in September 2011 passed, and on March 1, 2012 officially replaced the original building materials industry standard "the cement grinding aid" (JC/T667-2004), to implement,
Since then the cement grinding industry has entered a rational and well-documented era.
3. Future innovation period.
On November 31, 2012, the seventh member congress of China cement association was held in Beijing. The assembly elected the new leadership of the association. The President of the new China cement association, former President of the China cement association, former President of the China cement association, former President of the China cement association, former President of the China cement association, is the honorary President of the China cement association.
At the meeting, the new President Joe fong kuo put forward "the second generation of new dry process cement technology", compared with the first generation, the second generation of new dry process cement technology has the disposal of waste, make full use of waste heat, low carbon technology development and efficient function, prevention and control of pollutant discharge, reducing carbon dioxide emissions is to use computer and network information technology in the cement industry production of integrated technology, including the function of the whole cement production process and indicators to optimize.
In order to develop the new dry cement technology in the second generation, it is bound to strengthen the management and guidance in energy conservation and emission reduction. As one of the important energy-saving measures in cement industry, cement grinding agent is bound to be innovated.
