Human production and life are inseparable from polymer materials, ranging from household appliances to aviation. Polymer materials are widely used in communications, electronics, electrical, medical, chemical, aviation, aerospace, automotive, information, life sciences, etc. Many fields, so the research and application of polymer materials are of great significance. The construction of a polymer material laboratory is different from ordinary construction projects. Regardless of the scale, it is a comprehensive, professional, and systematic scientific building. If we can achieve unified deployment, overall coordination, and centralized construction in construction, project risks can be better controlled. CEIDI Xidi applied the EPC laboratory general contracting construction model to major clean engineering projects, which was well received by the project parties.

Saint-Gobain (China) Investment Co., Ltd. is a subsidiary of Saint-Gobain Group. It was established in China in 1996 and has a number of production plants. Its business includes providing automotive glass, architectural glass, abrasives, ceramic materials, refractory materials, high-performance plastics, The overall solution for gypsum building materials, industrial mortar and ductile iron pipes.

CEIDI Xidi also successfully implemented the EPC model in the construction of the 8,000 square meters Saint-Gobain R&D base plant area. Designed and constructed a purification plant in one of its production bases including a central laboratory of polymer materials. The main construction points of CEIDI in this project are:

1. The process layout is reasonable in the design. With 2 standardized polymer chemistry laboratories as the center, the building area is 80m2×2. The building size of each laboratory is approximately 12(L)×7(W) or 10(L)×8(W). At the same time, designers set up dressing, air shower and buffer rooms according to production needs to ensure that the flow of people, logistics, and sewage are clear to avoid cross-infection.

2. Matching selection of decoration materials in decoration. Decorative materials should be easy to clean and disinfect, corrosion-resistant, dust-free, non-cracking, smooth and waterproof, and the intersections should be treated with arcs for seamless joints;

3. Reasonable configuration of HVAC purification system. The configuration should be conducive to the disinfection and sterilization of the laboratory, the setting of the automatic control system and the energy-saving operation.

4. The ventilation and exhaust system is set as a full exhaust system. This project uses a full exhaust system because it involves experimental operations such as toxic, harmful, volatile solvents and chemical agents, and radioisotopes. Individual laboratories can organize the airflow (negative pressure) of the laboratory when necessary, so that the laboratory air can form a one-way airflow, and keep the airflow from the clean area to the polluted area to ensure that pathogenic biological factors will not escape from the laboratory to the surrounding environment.

CEIDI believes that when servicing customers whose main business is the development and production of high-tech products (polymer materials), the planning and design of laboratories and production areas, and the configuration of purification systems must be designed to protect the safety of experimenters. Prevent infection of bacteria and viruses, protect the safety of experimental samples, and ensure the accuracy of experimental results as a prerequisite. At the same time, many polymer material products are more harmful to the human body. EPC companies, which are specialized in the decoration of laboratories and production workshops, will also be more professional in the treatment of three wastes.

1. Exhaust gas, waste, and wastewater should be stored separately. Substances that may cause fire, explosion, or release flammable or toxic gas due to chemical reactions with other substances must be stored separately.

2. The gas discharged from the laboratory not only endangers people's health, but also causes environmental problems such as acid rain when discharged directly into the air. Therefore, the laboratory also needs to deal with the problem of exhaust gas. A number of exhaust gas purification treatment devices are installed on the top platform of the plant. The exhaust gas first passes through a reactor containing inorganic or organic raw materials to absorb most of the gas through dry adsorption, and then passes through a small tap water spray device to further absorb the soluble gas in the exhaust gas. . Through the above two-step purification process, the residual gas can basically meet the emission standard.
