3, worse on the snow! The stone processing industry is again being heavily tempered to remediate pollution problems ( read the original )
On May 16, the reporter went to the Darun Stone Factory in Baita Township, Luoyuan County. The entire factory door was closed and there was no one inside. The 8 large stone sawing machines in the factory had been dismantled. This is a microcosm of Luoyuan County's full efforts to carry out stone remediation. At present, 167 stone enterprises and 112 mines in the county have all been shut down.
The stone industry used to be the local pillar industry of Luoyuan. The annual output value was more than 5 billion yuan, and the annual tax revenue was more than 1 billion yuan. The county's mining stone industry directly employed nearly 10,000 people, and engaged in sales and other derivative industry chains. The number of people is nearly 100,000, accounting for 40% of the county's population. However, the environmental pollution problem caused by the stone industry has also plagued Luoyuan County.

4, Hebi, Faku Tao enterprises fully resume production ( read the original )
All along, the environmental protection and rectification trend is constantly invading the ceramic industry. As a result, many ceramic production areas have stopped production and undergo a rectification transition period. Then, look at the current situation of the local production areas.
Recently, a new round of environmental protection storms once again swept the ceramics industry, and caused a number of ceramic enterprises in Fujian, Guangdong, Sichuan, Guizhou, Hebi and other ceramic production areas to stop production, plus sorghum, Faku, etc., which were suspended due to environmental protection in April. In the production areas, this year's environmental remediation actions have blossomed throughout the country.
For this round of environmental protection, whether the ceramic enterprises are temporarily suspended or continue to stop production, the impact of the discontinuation on the ceramic industry chain, whether it will lead to tight supply of ceramic tile supply, and set off a new wave of price increases, causing great attention.

5. Selection and application of high performance phenolic resin for resin grinding wheel manufacturing ( read the original article )
Phenolic resins have been used for nearly a hundred years. Because phenolic resin raw materials are easy to obtain, the price is low, the production process and equipment are simple, and the products have excellent mechanical properties, heat resistance, cold resistance, electrical extinction, dimensional stability, molding processing, flame retardancy and low smoke. . Therefore, it has become an indispensable material in the industrial sector, and is widely used in various fields such as bonded abrasives, coated abrasives, friction materials, refractory materials, and bakelite powder, fireworks, and casting.
The phenolic resin is a polymer compound obtained by polycondensation of a phenol compound or an aldehyde compound as a raw material under the action of a catalyst, and a phenol resin which is polycondensed with phenol and formaldehyde is most important.
Phenolic resins are roughly classified into two types: thermosetting and thermoplastic. The thermosetting resin is synthesized by reacting phenol with an excess amount of formaldehyde under alkaline conditions; the thermoplastic resin is synthesized by reacting phenol with a small amount of formaldehyde under acidic conditions. The factors affecting the synthesis of phenolic resin and determining the properties of the resin are: chemical structure of the raw material and monomer functionality, molar ratio of phenolic aldehyde, properties of the catalyst and pH of the reaction medium.

6, China has issued a total of 2038 national environmental protection standards ( read the original )
The reporter learned from the Ministry of Environmental Protection on the 23rd that up to now, China has issued a total of 2,038 national environmental protection standards, 285 abolished standards, and 1,753 current standards.
At the press conference held on the same day, Zou Shoumin, Director of the Science and Technology Standards Department of the Ministry of Environmental Protection, introduced that China's two-level five-level environmental protection standard system has been formed, which are national and local standards, including environmental quality standards and pollutant discharge. (Control) standards, environmental monitoring standards, environmental management norms standards and environmental basic standards.
Local environmental standards have also developed rapidly. As of the end of the "Twelfth Five-Year Plan" period, the current mandatory local environmental protection standards passed the record reached 167, an increase of 104 from the end of the "Eleventh Five-Year Plan".
For a long time, the public has been very concerned about the lenient issue of environmental protection standards and the number of issues controlling pollutants.

7, Ming Yi intelligent Chen Jun: smart manufacturing makes the industry line more human ( read the original )
The 2017 “Dazhi Yunyun” Industry Development Forum hosted by the Hebei Provincial Department of Industry and Information Technology, the International Economic and Technical Cooperation Center of the Ministry of Industry and Information Technology, and the Xinhua News Agency Think Tank was held on May 18th in Langfang, Hebei Province. Chen Jun, Chairman of the Board of Directors attended and spoke.

It said that the current manufacturing industry's problems are that the product life cycle is relatively short, the product replacement is relatively fast, the investment pressure of enterprises to invest in the curing production line will be relatively large, and at the same time continue to meet market demand. So smart manufacturing solves these problems and makes the industry line more human.

10. How far is it from us to get rid of plunder and expand China's good market? ( read the original )
In the past two weeks in the United States, I first attended the Buffett annual meeting and the China-US investor cocktail reception, and then visited several cities. In this process, I have often been asked similar questions: the American dream is great, the US stocks are even new highs, the Chinese dream is great, and the economic growth rate is two or three times that of the United States, but why is the Chinese stock market falling?
More precisely, the question is: China's economy is very large and growing rapidly. Why is there no good, strong capital market?
At that time, my answer was nothing more than these angles: First, the US stock market can reflect the fundamentals of the economy, and the Chinese stock market cannot fully reflect the fundamentals of the economy. Tencent and Ali have risen by 30% to 40% this year. From $25 to more than $40, it has risen by more than 60%. Sina and Weibo have all hit new highs, but they are not listed on A-shares. Second, the US stock market is dominated by institutional investors, and the market is relatively rational. "Volunteerization" is still quite serious. It is a big ups and downs. After the skyrocketing, it is a plunge. After the plunge, it will take a long time to calm down the painful heart. It is difficult to quickly launch a round of vigorous love. Third, the performance of Chinese listed companies is unstable. The ability to eat and continue to create value is not strong. For example, the profitability of industrial enterprises has recently improved, 90% of which is based on the PPI (industrial producers' ex-factory price), which has nothing to do with the company's ability to innovate and manage.
