The rapid development of the city has also brought many side effects. For the moment, environmental protection has become the most serious challenge. The introduction of the “Strictest Environmental Protection Law in History†puts the issue under wide public view. Construction waterproofing membranes have also failed to escape the fate of the cracks. Whether it is from the national policy, industry-oriented or environmental protection awareness of the entire people, the concept of green building materials has become a social consensus. In order to seek the way out for the current environmental protection and energy conservation issues faced by the waterproofing industry, and ultimately realize the sustained and healthy development of the entire industry, the 2015 “Building Waterproof Industry Environmental Protection and Energy Innovation Technology Forum†was held in Beijing on October 11, 2015.
Environmental Protection Pressure Waterproof Industry Future Development
In the past five years, the development of the waterproofing industry has been the fastest in the past three years. Some industrial policies, production access conditions, etc. have also been gradually introduced, but the waterproofing industry also has 'backward overcapacity', 'low concentration', ' Environmental protection pressures increase the 'three major issues'. In the next few years, environmental protection pressures will increase or become the biggest challenges. Zhu Dongqing, chairman of the China Building Waterproofing Association, preached at the conference.
After the China Construction Waterproofing Association issued the 12th Five-Year Plan in 2010 and the introduction of the implementation rules for production of waterproof coiled coils and coils in 2013, the environment protection, equipment, and technology of the waterproofing coiled material have been further enhanced. Companies are also making many efforts in environmental protection. According to relevant statistics, the fixed investment in environmental protection equipment of waterproof enterprises has increased at a rate of 30% in the past five years.
A large amount of capital investment has led to a partial improvement in environmental protection issues, but it has not brought about the expected environmental protection effect for enterprises. This is because some companies are caught in some misunderstandings. It is hoped that with a once-and-for-all universal environmental protection device, pollutants such as highly polluted exhaust gas and dust will be filtered into products that meet the standard emission standards. And this is similar to building a dam on the Yangtze River, and it would be impractical to pass the dam's sewage into clean water. Changing thinking has become the key to many corporate governance pollution.
The root cause does not go to the old road of 'pollution first governance'
At the conference, from the China Academy of Building Materials Science Academy Suzhou Waterproofing Research Institute's Suzhou Waterproof Research Institute, the analysis of the major differences in domestic and foreign corporate governance pollution, domestic companies tried to address environmental issues solved on the post-processing of environmental protection equipment, and foreign Enterprises are treating them as issues of the previous paragraph. While we are still complacent about the huge environmental costs, some developed countries have already made environmental protection an essential early investment in the process of plant construction. Take Tajima, Japan as an example. The factory is surrounded by private houses, but effective environmental protection facilities make the Tajima company peaceful and coexist with the surrounding residents. 'Yong Yonghao preached.
It is reported that the asphalt used in the production of waterproof coiled materials of Tajima Corporation of Japan generally uses special asphalts such as modified asphalt, road asphalt, or waterproof asphalt with a softening point of 110 degrees Celsius. During the production of SBS modified asphalt membranes, it is not necessary to use waste. Powder replaces SBS modified materials. Strictly control the temperature of the asphalt heating, generally controlled within 200 degrees Celsius, to reduce the exhaust gas after heating the asphalt itself.
Therefore, the prevention of environmental pollution in the waterproof industry can not be followed by the old road of pollution control, but should follow the principle of 'prevention first, prevention and control, comprehensive management'.
However, how is the front-end pollution problem in the waterproofing industry caused? According to an interview with the reporter, as bitumen fume and industrial dust are easily produced during the production of bituminous waterproof membranes, they must be treated with bitumen fume to meet environmental protection requirements. However, many companies that go to earn a place in the sales market and obtain economic benefits will meet the bidding method for low-price bids and reduce product costs. In the production process of SBS modified bitumen, regardless of the quality of production capacity, waste rubber powder is used instead. The SBS modified material is accompanied by a large amount of waste engine oil as the solvent; in order to further reduce the cost, more stone powder is added to force the temperature of the asphalt heating to be increased to 200 degrees or more, which increases the difficulty in handling the asphalt gas. Asphalt flue gas, waste rubber powder and waste oil, as well as a large amount of sewage odor, are diffused in the atmosphere and seriously affect the environment.
Faced with such a status quo, where should the waterproof company go? The representatives of the companies at the conference made technical claims. Shanghai Xulu Environmental Protection Technology Co., Ltd. Professor Bao Xinxin, Chinese Academy of Building Research Institute of Building Materials Dr. Wang Hailong, Shanghai Sun Jie Environmental Technology Co., Ltd. General Manager Cai Hongbing respectively on the power wave + photocatalytic oxidation process program and application, water spray + High-voltage capture + UV oxidation process and application, water spray + plasma process program and application are introduced. Zhou Shengping, technical manager of Shanghai Xinti New Material Technology Consulting Co., Ltd., introduced the related technologies of wastewater reuse.
In order to meet the requirements of high speed, high precision and high processing life in modern aluminum alloy parts processing, PCD Milling Inserts has gradually become the best choice for processing. It can have higher cutting speed and tools life is dozens times longer than Carbide Inserts. In order to realize the optimization of productivity and machining quality, it is necessary to select correct type and geometric parameters of PCD Inserts carefully to meet different machining requirements, such as insert geometry, cutting edge strength, and the type of chip breakers.
