Dayang Biology: Focus on the main business, be specialized, refined and strong

Zhejiang Jiande scenic ocean town, there is a continuous development of township enterprises from expanding growth businesses listed companies, it is the Zhejiang Ocean Bio-Technology Group Co.
, Ltd
.

Although the market size of its leading products is not huge, its production capacity has occupied a dominant position in the domestic and foreign markets

The largest production capacity

The scale of production capacity takes the lead.

Dayang Bio, established in 1976, has a history of 45 years
.

The company was listed on the NEEQ in 2016 and listed on the Shenzhen Stock Exchange in 2020

Chen Yanggui, the chairman of the company, told the research team that the company's flagship product is the potassium carbonate series, which accounts for about 2/3 of the company's operating income
.

"At present, the company's potassium carbonate production uses the ion exchange process.
In the early stage of reform and opening up, there were 40 or 50 similar companies in China.
However, due to environmental protection issues in wastewater treatment, most companies have stopped production and are still using this process.
Only we and a company in Shanxi are left on the route
.

From the perspective of production capacity, the company's comprehensive production capacity of potassium carbonate (including potassium bicarbonate equivalent) reached 77,000 tons/year last year, ranking first in the industry in China

In addition to the absolute advantage in the production capacity of potash products, Dayang Bio's veterinary medicine and fluorine-containing fine chemicals main products are also in a leading position in the production capacity of subdivisions
.

　　In the veterinary medicine sector, Amproline Hydrochloride produced by Ocean Bio is a widely used animal anticoccidial drug on the market, mainly used for the prevention and treatment of poultry and other breeding
.

At present, the company is the only domestic enterprise that produces amproline hydrochloride, with an existing production capacity of 600 tons/year, and 80% of its products are for export

　　In the fluorine-containing fine chemicals segment, the company's main products are 2-chloro-6-fluorobenzaldehyde and 2-chloro-6-fluorochlorobenzyl
.

Among them, 2-chloro-6-fluorobenzaldehyde is mainly used in the field of medicine, as the main upstream raw material of the antibiotic flucloxacillin, the current production capacity is about 500 tons/year

　　"Although these two fluorinated products are not large in scale, only our company is producing them in China
.

The company is also building an annual production of 1,500 tons of 2-chloro-6-fluorobenzaldehyde and other aromatic hydrocarbons in Fujian, which has resource endowments and geographical advantages.

　　Remarkable technological innovation

　　"For so many years, many companies in the industry have been eliminated one after another, and the survival of our company is mainly due to the independent innovation of core technologies and the emphasis on the introduction and training of scientific and technological talents
.

" Chen Yanggui said

　　According to the research team's understanding, in the potassium carbonate and potassium bicarbonate manufacturing industry, the ion exchange closed loop system independently developed by Dayang Biotechnology to produce potassium carbonate has realized the complete recycling of production water; the ion exchange method low temperature self-carbonization production of potassium carbonate technology has realized the product Low-temperature self-carbonization production was recognized by the Ministry of Science and Technology as the "National Torch Program Industrialization Demonstration Project"
.

　　The research team also learned that ion exchange and ion-exchange membrane electrolysis-carbonization are the current mainstream production processes for potassium carbonate and potassium bicarbonate, and both use potassium chloride as the main raw material.
The two methods have their own merits and are difficult to replace each other
.

However, under the goal of carbon peak and carbon neutrality in the future, the ion exchange method adopted by Ocean Biology has certain advancement in saving energy consumption

　　The key to technological innovation lies in talents
.
Dayang Biology has always attached great importance to technology research and development and independent innovation, and puts the introduction and training of talents as the top priority of its work
.

　　At present, Dayang Bio has more than 50 full-time R&D personnel, and has established Zhejiang Postdoctoral Workstation, Dayang Nanomaterials Provincial High-tech Research and Development Center, Provincial Enterprise Technology Center and Zhejiang Dayang Science and Technology Potash Research Institute
.
The company cultivates R&D teams by introducing domestic and foreign postdoctoral fellows and co-training with their mentors
.
In addition, the company has established close cooperation with Zhejiang University, Zhejiang University of Technology, and Dalian University of Technology
.

　　"Now the company's products are in a leading position, coupled with a good platform for listed companies and convenient and superior living conditions, attract high-level talents to join, and inject a source of power for the company's development
.
" Chen Yanggui said
.

　　Focus on dual-carbon transformation and upgrading

　Focus on dual-carbon transformation and upgrading　focus on dual-carbon transformation and upgrading

　　This year is the first year of the "14th Five-Year Plan".
Despite the impact of foreign epidemics, Dayang Biotechnology has achieved steady growth in its production and operations
.

　　Next, how should the enterprise develop its layout? In this regard, Chen Yanggui believes that the implementation of carbon peaking and carbon neutral strategy will put forward new requirements for the industry, and in the future, it will rely on technological innovation to achieve carbon emission reduction
.

　　In terms of production, the company focuses on "mechanization substitution, automation to reduce personnel", and continuously improves labor efficiency
.
In the later period, it will be implemented through fund-raising projects to carry out automation transformation, and strive to improve the company's production and operation automation and informatization to a new level, so as to greatly reduce labor costs
.

　　"The Hangzhou area where we are located requires higher levels of safety and environmental protection
.
Especially under the strategic background of carbon peaking and carbon neutrality, the company will accelerate technological innovation in the later stage, increase development and introduction of technology and equipment, and increase carbon dioxide Potassium and other processes have been further optimized, and ammonium chloride devices have adopted modern processes, and strive to further reduce energy consumption indicators
.
" Chen Yanggui said that the company’s closed-circuit technology and the original four-effect belt heat pump, DC falling film low-temperature continuous evaporation and crystallization technology to recover ammonia nitrogen Waste water is a domestic initiative
.
At present, the company’s first more advanced fourth-generation technology has been put into use in March this year, and it is running well.
The steam consumption per ton of product is only 1/10 of that of the third-generation technology.
The steam saving effect is obvious.
The second set of equipment will be launched this month.
Put into use to provide steam guarantee for the expansion of potassium carbonate production capacity under the carbon peak target
.
In the next 3 to 5 years, energy saving and consumption reduction will be an important starting point for enterprises
.

　　In addition, in terms of industrial layout, the company will continue to strengthen the extension of the potassium carbonate industry chain, not only in terms of upstream raw materials, but more importantly, to strengthen cooperation with downstream companies to realize resource utilization and form a large cycle of potassium carbonate industry and its downstream industries.
