引言
中昊（大连）化工研究设计院有限公司 (China Haohua (Dalian) Research & Design Institute of Chemical Industry Co., Ltd.), usually abbreviated as Dalian Institute or Dalian Chemical Research and Design Institute, is a research-oriented chemical enterprise located in Dalian City, Liaoning Province, China. It integrates chemical research and development, process and engineering design, technical services, production, technology transfer, and specialty chemical sales.
The institute is the successor to the former Ministry of Chemical Industry Soda Ash Industry Research Institute, established in 1959 with support from renowned soda ash expert Hou Debang. Its historical foundation lies in inorganic chemical engineering and soda ash production, while current operations have expanded to fine chemicals, polymer-related additives, water-soluble polymers, chemical intermediates, corrosion protection, cleaning technologies, and custom chemical development.
The company belongs to China Haohua Chemical Group and sits within the broader chemical industry structure of Sinochem Holdings Co., Ltd. Its positioning is unique as it operates simultaneously as a research institution, engineering organization, specialty chemical manufacturer, and technical service provider. It is not merely a commodity polymer manufacturer or plastics processor but participates in the plastics value chain through additives, polymer materials and intermediates, formulation-related technologies, and chemical production engineering services.
History and Development
Establishment and Soda Ash Research
The institute was founded in 1959 as the Ministry of Chemical Industry Soda Ash Industry Research Institute. Its establishment reflected the strategic importance of soda ash, a key inorganic chemical used in glass, detergents, chemicals, metallurgy, and other industrial sectors.
Early work focused on soda ash production process research, technical information, engineering design, and industrial support. This foundation shaped its ongoing role in chemical process development and engineering rather than purely laboratory research.
Institutional Restructuring
In 1999, the institute joined the Haohua Chemical Technology Group structure. It subsequently became part of the broader state-owned chemical enterprise system linked to China National Chemical Corporation and later Sinochem Holdings.
In June 2012, the organization was restructured and adopted its current name China Haohua (Dalian) Research & Design Institute of Chemical Industry Co., Ltd. This change formally established its development as an integrated enterprise combining research, design, manufacturing, and technical services.
Expansion into Specialty Chemicals and Polymers
Over time, the institute expanded its scope from soda ash technology to fine chemicals, polymer additives, water-soluble polymers, chemical intermediates, and custom products. Publicly described development milestones include:
- Recognition as a National High-Tech Enterprise.
- Establishment of a provincial-level enterprise technology center.
- Creation of the National Water-Soluble Polymer Technology Development Center.
- Participation in the Water-Soluble Polymer Strategic Industry Technology Innovation Alliance.
- Recognition as an organization involved in national technology transfer and commercialization activities.
These developments reflect China's chemical industry's broader shift from process replication and basic chemical capacity toward specialty materials, proprietary formulations, and industrial technical services.
Business Operations and Segments
The institute's activities can be divided into several closely related operational areas.
| Operational Area | Main Activities |
|---|---|
| Research & Development | New chemicals, polymer-related materials, additives, intermediates, process technologies, and custom chemical solutions |
| Engineering Design | Chemical process design, feasibility studies, engineering consulting, plant and equipment design, and project support |
| Specialty Chemical Production | Manufacturing and sales of selected fine chemicals, additives, intermediates, and related products |
| Technical Services | Technology transfer, process optimization, analytical testing, corrosion protection, chemical cleaning, and industrial support |
| Industry Information & Publishing | Technical information, professional journals, standards-related communications, and industry knowledge services |
This combination enables the company to support projects across multiple stages, from laboratory development and pilot testing to process design, plant implementation, production, and technical improvement.
Research & Development
Research activities focus on chemical synthesis, process development, formulation, polymer-related materials, and industrialization of laboratory results. The institute's model is application-oriented, meaning projects are typically tied to manufacturing requirements, process economics, product performance, or specific customer needs.
Engineering & Consulting
The organization provides engineering and consulting services for chemical facilities. Its publicly listed capabilities include chemical engineering consulting and design, pressure vessel design, pressure piping design, project management, and related technical services.
These capabilities are relevant to plastics and polymer producers because additive and intermediate manufacturing requires controlled reaction systems, separation equipment, storage facilities, utilities, environmental systems, and process safety infrastructure.
Production & Commercialization
The institute also operates as a production enterprise. Its commercial activities include manufacturing and sales of specialty chemicals, polymer additives, UV absorbers, antioxidants, and related products. Its production role provides a direct avenue to validate technologies under industrial conditions and commercialize research outcomes.
Products & Technologies
Polymer Additives
The institute is involved in the development and production of light stabilizers, UV absorbers, and antioxidants. These materials are important for plastics because polymers degrade under UV radiation, heat, oxygen, and long-term environmental exposure.
Typical functions include:
- Reducing photochemical degradation caused by UV radiation.
- Limiting discoloration and mechanical property loss.
- Improving resistance to thermal oxidation during processing and service.
- Extending the service life of plastic products.
- Supporting performance in coatings, elastomers, fibers, and polymer compounds.
Such additives are used at relatively low concentrations but can have a significant impact on product durability. Their performance depends on compatibility with the matrix polymer, migration resistance, processing temperature, exposure conditions, and interactions with other additives.
Water-Soluble Polymers
Water-soluble polymers represent another major technology area. Such materials find use in water treatment, industrial processing, mining, papermaking, textiles, construction materials, and chemical formulations. Performance depends on molecular weight, charge density, solubility, rheology, and resistance to the intended chemical environment.
The institute's establishment of a national water-soluble polymer technology development platform indicates its emphasis on applied polymer research and industrial technology transfer. This area connects the organization to the broader specialty polymers sector, where performance is often determined by formulation and application rather than production volume alone.
Chemical Intermediates
The institute develops and supplies chemical intermediates used in the manufacture of fine chemicals, pharmaceuticals, agrochemicals, dyes, polymer additives, and other products. Intermediates may be produced via batch or continuous chemical processes, depending on reaction kinetics, scale, hazard profile, and required product quality.
For markets related to plastics, intermediates can support the manufacture of stabilizers, modifiers, coating ingredients, and other functional materials. The company also engages in custom chemical development, including adjusting synthetic routes, improving purity, or preparing products to customer specifications.
Soda Ash & Inorganic Chemical Technology
The institute retains capabilities related to soda ash and the broader inorganic chemicals sector from its historical roots.
