Why choose professional cleanroom construction?

Cleanroom By precisely controlling parameters such as particulate concentration, temperature, humidity, and pressure difference in the air, it provides dust-free, sterile, and constant environmental support for high-precision experiments and production. Its application scenarios cover:

Semiconductor manufacturing ：The chip lithography process requires a cleanliness level of ISO class 3, temperature fluctuation ≤±0.5℃, humidity fluctuation ≤±2%RH, and minor deviations will directly affect the yield.

Biomedicine ：Vaccine research and cell culture require strict control of the microbial concentration in the cleanroom to ensure the reliability of experimental data.

Optical instruments ：Lens coating requires an ultra-clean environment (dust particles ≤0.1μm) to avoid dust reducing optical performance.

New energy and aerospace ：Precision parts processing relies on a clean space with anti-vibration and constant temperature and humidity to ensure the accuracy of material performance testing. 。

If the cleanroom environment does not meet the standards, it will lead to product defects and experimental failures, or even safety hazards. Therefore, professional design and construction are the core guarantee of cleanroom efficiency.

Nanjing Expansion Technology's four core advantages in cleanroom construction

1. Precise design: Scientific planning, matching international standards

We are based on ISO 14644, GMP and other standards, combined with process flow to customize cleanroom solutions. Through CFD airflow simulation to optimize the layout, ensure reasonable airflow, uniform temperature and humidity (±0.3℃/±1.5%RH accuracy), and integrate anti-static and anti-vibration design to meet the stringent needs of semiconductors, biosafety laboratories, etc.

2. Cutting-edge technology: Independent research and development, breaking industry limits

High-precision environmental control system: Using high-efficiency filtration ( HEPA/ULPA), electrostatic dust removal, chemical adsorption and other multi-technology integration, the cleanliness can reach Class 10 and above, particle filtration efficiency ≥99.99%.

Intelligent temperature and humidity control: Independently developed precision air conditioning units, temperature fluctuation ≤±0.005℃, humidity fluctuation ≤±1%RH, suitable for electronic display screen manufacturing, aerospace material testing and other ultra-precision scenarios.

Anti-vibration solution: Through elastic vibration isolation foundation and damping material application, the vibration value is reduced to below the equipment's allowable threshold, successfully applied to major projects such as the Wuhan Light Source.

3. Strict construction: Quality first, details win

Material selection: Using anti-static color-coated steel plates, epoxy self-leveling floor, and aluminum alloy sealing structure to ensure airtightness and durability.

Construction capacity: 6000㎡ cleanroom delivered in 40 days; sealed construction eliminates cold bridge effect, energy saving rate increased by 30%.

4. Full-process service: Worry-free operation and maintenance, long-term empowerment

Provide 24-hour intelligent monitoring, regular calibration, and equipment maintenance services, and equipped with an emergency response mechanism to ensure the stable operation of the cleanroom 24/7. We also launched the "integrated laboratory" general contracting model, integrating ventilation, fire protection, wastewater treatment and other subsystems to eliminate the hidden dangers of cross-professional cooperation.

Successful cases: Defining industry benchmarks with technological strength

A certain international chip giant: A Class 100 cleanroom project, achieving temperature control of ±0.1℃ and humidity control of ±1%RH, helping to improve chip yield by 20%.

A certain light source laboratory: Overcoming the challenges of precise temperature control and anti-vibration in the constant temperature room, becoming a model for light source laboratories.

A certain large scientific device: Achieved a temperature control fluctuation index of up to ±0.1℃, relative humidity ≤60%, cleanliness ISO4~ISO7, noise ≤60dB(A)~65dB(A).
