The company has been rated as Guangdong Province and national environmental protection backbone enterprises, "National Resources Conservation and Environmental Protection Major Demonstration Project" unit, "the first batch of pilot units of circular economy" and "national high-tech enterprises," 2005-2009 continuous Selected "Forbes" "China 100 potential list."
Multi-channel multi-level upgrade the company's technical level
Over the years, Dongjiang Environmental Protection has promoted the technical level of the Company through multi-channel and multi-level cooperation. Production, education and research cooperation plays an extremely important role in this respect. The company has with the Chinese Academy of Sciences, Tsinghua University, Huazhong University of Science and Technology, Southern University of Science and Technology, Hefei University of Technology and other universities, research institutes to carry out research cooperation in production, research and comprehensive management of river pollution and ecological restoration, declare the Guangdong Provincial Engineering Center and technical personnel training And the exchange of output issues, hazardous waste disposal and detection of persistent pollutants to carry out scientific and technological research and platform construction cooperation. Particularly worth mentioning is that in November 2016, Dongjiang Environmental Protection agreed with the government of Jianye District in Nanjing, Jiangsu Dongheng International Group and Monash University in Australia to set up the "Sponsor City and Research Center of China and Australia".
The Dongjiang environmental protection won the second prize of national scientific and technological progress, is the result of joint efforts with Tsinghua University. The technology for the first time in the country to build a regional renewable resources Internet + renewable resource recovery system technology and commercial operation system to control the material flow and a large number of common material and common cycle of the key technologies as a means to form a "system integration Planning, intelligent classification of recycling, clean waste regeneration, management policy support "as the characteristics of urban recycling economy common technology development model. The research results of the project have a positive and positive effect on the scientific and technological progress and technological upgrading of the national environmental protection industry.
Dongjiang Environmental Protection and Tsinghua University conducted a study on the key technologies such as the comprehensive utilization of precious metals, the recycling of scrap metal materials and the deep resource of polyurethane foam, and the transformation of the key technologies of dismantling and recycling of electronic wastes. Annual dismantling capacity of 10,000 tons of waste electrical and electronic products demonstration project construction and operation management, including waste electrical and electronic products processing facilities, secondary pollution control facilities, safety operations facilities planning, construction, rectification and so on. Relevant research results have been granted 8 invention patents, 7 utility model patents.
In the future, Dongjiang Environmental Protection will also invest in R & D investment and intellectual property through an open R & D management platform, the establishment and management of a distributed technology R & D system, a technology R & D team management mode combined with production, a wide range of domestic and international research and technological cooperation, And other areas, to promote the company's technology research and development, production and application of technological advances, the output of technical achievements and practical application, create economic benefits, technology to lead the company's development.
Business network covering the core area of ​​hazardous waste industry
At present, Dongjiang Environmental Protection employs more than 800 technicians and annually processes over 3.7 million tons of industrial and municipal waste for comprehensive utilization and disposal. It possesses 44 hazardous waste management qualifications and over 1.4 million tons of hazardous waste treatment capacity annually. More than 60 Its branches, subsidiaries and business networks cover the core areas of hazardous waste industry such as the Pearl River Delta, the Yangtze River Delta, Beijing-Tianjin-Hebei, the Bohai Rim and the Midwest, serving over 15,000 customers. It is the largest hazardous waste treatment and disposal enterprise in China.
For the main application of the project research results in the future, Dongjiang Environmental Protection said that the research results in the industry has universal applicability, can be widely used in urban disposal and recycling of typical waste and so on. The common system of urban circular economy development has been popularized and applied in many cities during the project implementation. The key technologies and complete sets of equipment for project development have been transformed and applied in the project completion units and carried out in more than ten enterprises To promote. The project authorizes about 50 invention patents, published nearly 300 papers, monographs more than 10 copies.
The next step, Dongjiang environmental research will focus on high concentration of refractory organic wastewater technology research and transformation of technical achievements, complete cement kiln co-disposal, plasma melting, rotary kiln incineration technology in the industrialization of hazardous waste pretreatment, compatibility, etc. In terms of R & D and industrialization of key technical issues, the Group will continue to promote the development of co-disposal technologies for hazardous wastes and provide strong technical support for the strategy of building a new smart city in our country.
Reactive Dyes Thickening Agent
A reactive dye Thickening Agent is a substance used in the textile industry to enhance the viscosity of reactive dye solutions, making them easier to handle and apply. Reactive dyes are known for their high affinity to cellulose fibers, such as cotton, but they can sometimes be difficult to work with due to their low viscosity. The addition of a thickening agent helps to stabilize the dye solution, improving its flow properties.
There are various types of thickening agents that can be used depending on the specific requirements of the dyeing process:
1. **Cellulose Derivatives**: These include materials like carboxymethyl cellulose (CMC), hydroxypropyl methyl cellulose (HPMC), and others. They form a gel-like structure when dissolved in water, which increases the viscosity of the dye solution.
2. **Polyacrylates**: These are synthetic polymers that can be used to increase the viscosity of reactive dye solutions. They provide good stability and are often used in conjunction with other thickeners.
3. **Polysaccharides**: Natural polymers such as starch or xanthan gum can also serve as effective thickening agents in reactive dye solutions.
4. **Polyvinyl Alcohol (PVA)**: PVA is another synthetic polymer that can increase the viscosity of reactive dye solutions, making them more manageable during the dyeing process.
When using a thickening agent, it's important to consider factors such as the type of fiber being dyed, the desired level of viscosity, and any potential interactions between the thickener and other components of the dye bath. Proper dosing is crucial to achieve the optimal thickening effect without compromising the colorfastness or the overall quality of the finished product.
