Technical Analysis of the Entire Process of Material Laboratory Construction: Professional Construction Strategies from Design to Construction

Against the backdrop of the intertwined new round of technological revolution and industrial transformation, materials science is undergoing a profound transformation from traditional experience-driven to precision technology innovation. Materials experiments, as the core means of revealing material properties and exploring preparation processes, place higher demands on the functionality and professionalism of laboratories. The construction of materials laboratories is not simply a matter of space construction, but a systematic project covering multiple technical aspects such as materials laboratory design, materials laboratory decoration, and materials laboratory construction.

I. Materials Laboratory Design: Building a Scientific Functional System with Technological Innovation

Materials laboratory design is the first step in technology implementation, and it needs to achieve dual optimization of function and performance through a systematic technical architecture. In terms of spatial planning, modular design technology is adopted to divide the laboratory into functional units such as pre-treatment area, precision detection area, high-temperature/high-pressure test area, and sample storage area according to the experimental type. The ventilation efficiency of each area is ensured by airflow organization simulation technology. For example, a universal exhaust hood and a variable air volume ventilation system (VAV) are set up in the chemical analysis area to achieve a clean standard with an air exchange rate ≥12 times/hour. For the precision instrument room, constant temperature and humidity control technology is introduced, and a high-precision air conditioning system is used to control the temperature and humidity fluctuations within ±0.5℃ and ±2% RH. At the same time, an electromagnetic shielding network and grounding system design are adopted to reduce the electromagnetic interference intensity to below 50dB, ensuring the stable operation of precision equipment such as X-ray diffractometer (XRD) and scanning electron microscope (SEM).

In terms of safety technology design, nano-aerogel insulation materials are used for the high-temperature test area, together with an automatic sprinkler system and a gas leak monitoring device, to achieve a fire warning response time <10 seconds; the walls of the high-pressure test area are made of explosion-proof concrete, combined with explosion pressure calculation technology, to ensure that the structure can withstand ≥0.5MPa instantaneous impact pressure. In addition, intelligent design technology runs through the entire process. Through the laboratory management system (LIMS), equipment control, environmental monitoring, and security alarm functions are integrated to achieve digital management of experimental processes and real-time risk warning.

II. Materials Laboratory Decoration: Technological Implementation of Special Materials and Processes

Materials laboratory decoration is the concrete process of design concepts, and the core lies in the selection of special functional materials and the technical control of construction processes. The floor decoration adopts a combination of epoxy self-leveling mortar (compressive strength ≥70MPa) and polyvinyl chloride (PVC) homogeneous permeable floor. The former is suitable for heavy equipment areas, while the latter has excellent acid and alkali resistance (resistant to 98% sulfuric acid and 30% sodium hydroxide) in chemical test areas. The walls use magnesium oxide fireproof board (fire rating A1) and stainless steel anti-bacterial board. The former meets laboratory fire protection standards, while the latter achieves ≥6H surface hardness and easy cleaning characteristics in high-frequency contact areas such as equipment corridors.

The technical standards of laboratory furniture directly affect the user experience. The central laboratory bench adopts an all-steel frame structure, and the countertop uses solid phenolic resin board (impact resistance ≥50kg·cm). The edges are rounded to eliminate safety hazards; the fume hood is equipped with a variable air volume speed control system to ensure that the face velocity is stable at 0.5±0.1m/s. Combined with optimized design of the flow guide plate, the pollutant collection efficiency is increased by 30%. The lighting system adopts LED anti-glare lights (illuminance ≥500lux) and intelligent dimming technology, combined with a natural light collection system, saving 30% energy while avoiding glare interference with fine operations such as microscopic observation.

III. Materials Laboratory Construction: Full-Process Technical Control to Ensure Quality Implementation

Materials laboratory construction is a complex process involving the coordination of multiple professional technologies, and it requires fine-grained management to accurately reproduce the design intent. In the early stage of construction, building information modeling (BIM) technology is used for 3D modeling to simulate the spatial layout of ventilation pipes and electrical pipelines in advance, solving the problem of pipeline collisions in traditional construction and improving space utilization by more than 15%. In the foundation construction stage, a suspended floor vibration reduction technology is used for high-precision equipment areas. By combining spring vibration isolators and damping pads, the vibration transmission rate is controlled below 10%, meeting the installation requirements of ultra-precision instruments such as atomic force microscopes (AFM).

The water and electricity installation links follow strict technical standards: the electrical system adopts the TN-S grounding system, with grounding resistance ≤1Ω, and the precision equipment lines are laid separately and use metal shielded conduits; the water supply and drainage system distinguishes between ordinary water and deionized water pipelines. The latter uses 316L stainless steel pipes and compression fitting technology to avoid water pollution, and an online conductivity monitor (accuracy ±0.1μS/cm) is configured in the pure water preparation room. In terms of construction quality control, a full-process detection system is established to conduct air volume balance tests and airtightness tests (leakage rate ≤5%) on the ventilation system, and dust particle counting (≥0.5μm particle count ≤35200/m³) on the clean room to ensure that all technical indicators meet the relevant laboratory certification requirements.

IV. Technological Integration Empowers the Full Life Cycle Value of the Laboratory

The core competitiveness of materials laboratory construction lies in the integration ability of the technology chain. As a professional laboratory EPC service provider, it is necessary to integrate cutting-edge technological concepts into materials laboratory design, achieve precise application of functional materials in materials laboratory decoration, and implement process standards and quality control in materials laboratory construction, forming a full-process closed loop from technical scheme design to on-site implementation. By organically combining ventilation control technology, intelligent monitoring technology, and vibration and noise reduction technology, it can not only create a safe and efficient experimental environment, but also provide researchers with a sustainable upgrade innovation platform—for example, reserving modular expansion space and intelligent system compatible interfaces to meet the needs of laboratory equipment iteration and functional expansion in the next 5-10 years.

Materials laboratory construction is a technology-intensive systematic project, and every link carries the dual requirements of professionalism and scientificity. From the functional technical architecture of materials laboratory design, to the special process application of materials laboratory decoration, and to the fine-grained control of materials laboratory construction, only by driving technological innovation can a modern materials laboratory integrating functionality, safety, and forward-looking vision be built. We always adhere to combining engineering experience with technological research and development to provide customers with full-process technical solutions, helping materials science research to continuously advance on the road of precision and efficiency, and injecting strong technological impetus into industrial upgrading.
