With the rapid development of high-tech industries such as semiconductors, biomedicine, and precision manufacturing, clean space technology has become a core element in ensuring product quality and improving production efficiency. Shenzhen Huajianjing Construction Engineering Co., Ltd. (referred to as Huajianjing), as a leading clean space service provider in China, has formed a comprehensive solution covering all scenarios such as dust-free workshops, clean rooms, purification workshops, and sterile workshops with more than 20 years of industry experience, providing one-stop services from design to construction for high-end manufacturing industries. This article will deeply analyze how Huajianjing drives clean space construction to new heights through innovation from four dimensions: technological system, industry application, service advantages, and future trends.
1、 Technical system: Integration of standardization and intelligence throughout the entire process
Huajianjing's Clean Space Solution; Three level purification system; As the core, it covers three major technical modules: air purification, temperature and humidity control, and microbial inhibition. In the air purification process, the company adopts a three-stage filtration system of primary efficiency, medium efficiency, and high efficiency (HEPA), which is dynamically adjusted with FFU (fan filtration unit) to achieve precise control of ISO 1-9 cleanliness levels. For example, in a semiconductor wafer fab project, thousands of FFUs are deployed in conjunction with intelligent control systems to maintain a stable particle concentration below 0.1 μ m in the workshop, meeting the requirements of a 12 inch wafer production environment.
In terms of temperature and humidity control, the Intelligent Environmental Management System (IEMS) developed by Huajianjing collects real-time data through sensor networks and dynamically adjusts the operating parameters of air conditioning units using AI algorithms. In the biopharmaceutical aseptic workshop project, the system can control temperature fluctuations within a certain range; 0.5 ℃, humidity fluctuation controlled within± Within 3% RH, while maintaining positive pressure to prevent external contamination from entering, ensuring that the drug production environment meets GMP standards.
Microbial inhibition technology is another major breakthrough of Huajianjing. The company's original; Photocatalysis+Electrostatic Adsorption; Composite sterilization technology, through the synergistic effect of UVC ultraviolet light and nano titanium dioxide coating, can achieve a 99.99% bacterial inactivation rate. In the application of sterile medical equipment workshops, this technology reduces the concentration of planktonic bacteria from the conventional scheme of 100 CFU/m³ Reduce to 10CFU/m³ The following significantly improves the product qualification rate.
2、 Industry application: Customized solutions empower high-end manufacturing
Huajianjing's services cover four core areas: semiconductors, biomedicine, food processing, and precision electronics, providing differentiated solutions tailored to the characteristics of different industries. In the semiconductor industry, the company designed a Class 1000 clean room for a 12 inch wafer fab. By using special materials such as anti-static PVC flooring, sealed clean lighting fixtures, airtight doors and windows, and strict wall through pipe sealing technology, the workshop's ESD (electrostatic discharge) protection level reached Class 100 standard, effectively reducing chip yield loss.
In the field of biomedicine, Huajianjing has created a 10000 level sterile workshop for a vaccine production enterprise, which innovatively adopts the "; Double corridor+airlock room” Design and implement strict separation of character flow. By setting up transition areas such as buffer rooms and transfer windows, combined with automatic access control systems and air shower rooms, the risk of cross contamination is reduced to less than 0.01%. This project has passed the Chinese GMP certification and the EU EDQM certification, helping the company's products export to the European market.
In the food processing industry, Huajianjing designed a 300000 level purification workshop for a dairy enterprise. The workshop adopts 304 stainless steel walls, epoxy self leveling floors, and food grade sealant, combined with ozone disinfection system and air circulation purification device, to achieve better microbiological indicators than the requirements of GB 14881-2013 standard. After the project is put into operation, the product shelf life is extended by 30% and the market complaint rate decreases by 75%.
3、 Service advantage: Full lifecycle management capability
Huajianjing's services run through the entire lifecycle of the project, forming a '; Requirement analysis - scheme design - construction management - acceptance and delivery - operation and maintenance services; The closed-loop management system. In the requirements analysis stage, the company forms a multidisciplinary team consisting of clean technology experts, process engineers, and equipment suppliers. Through CFD (Computational Fluid Dynamics) simulation and BIM (Building Information Modeling) technology, key parameters such as airflow organization and pressure gradient are predicted in advance to optimize the design scheme.
In the construction management process, Huajianjing strictly implements the ISO 9001 quality management system, adopts modular installation technology and precision instruments such as laser level to ensure the airtightness of the enclosure structure at 0.05Pa/m; The ground flatness error is 2mm/2m. In the construction of a certain optoelectronic display project, the company shortened the construction period by 40% and achieved zero rework rate through prefabricated wall panels and prefabricated pipeline systems.
In terms of operation and maintenance services, Huajianjing has developed an intelligent operation and maintenance platform (IOT-FM), which deploys thousands of sensors to monitor real-time parameters such as cleanliness, temperature and humidity, and pressure difference, and combines predictive maintenance algorithms to warn of equipment failures in advance. After applying the platform, a pharmaceutical company reduced equipment downtime by 60% and annual operation and maintenance costs by 25%.
4、 Future trend: Green and digital dual wheel drive
Facing“ Dual carbon; Facing the dual challenges of goals and Industry 4.0, Huajianjing is accelerating the layout of green and clean technologies and digital solutions. In terms of greening, the company's research and development; Heat recovery air conditioning unit; The energy recovery rate of exhaust can be increased to 75%, and with the cooperation of photovoltaic power generation system, the comprehensive energy consumption of a clean workshop in an electronics factory can be reduced by 30%. At the same time, the company is exploring the use of biobased materials to replace traditional epoxy resins, reducing VOC emissions by over 90%.
In the field of digitalization, Huajianjing collaborates with companies such as Huawei and Siemens to develop; Digital Twin Cleanroom; By using 3D modeling and real-time data mapping, dynamic optimization of production environment and process parameters can be achieved. In a pilot chip packaging project, this technology increased product yield by 5% and overall equipment efficiency (OEE) by 12%.
Looking ahead to 2026, Huajian Net will continue to deepen; Technology+Service; The dual wheel drive strategy aims to build an open innovation ecosystem, collaborate with universities and research institutions to conduct cutting-edge technology research, promote the development of clean space technology towards higher cleanliness, lower energy consumption, and greater intelligence, and provide Chinese solutions for the global high-end manufacturing industry.
As a benchmark enterprise in the field of clean space, Huajianjing is using technological innovation as the engine and customer demand as the guide. Through standardized services throughout the entire process and forward-looking technological layout, it is helping China's manufacturing to transform and upgrade to China's intelligent manufacturing. Under the national strategic background of domestic substitution in the semiconductor industry and research and development of innovative biopharmaceuticals, Huajianjing's solutions will continue to release value and contribute to building a safe, efficient, and sustainable modern industrial environment.
