The deformable nature and multi-functional adaptability of industrial flexible doors make them valuable in innovative scenarios. Below are key application：
Industrial Factories
In aircraft manufacturing or heavy machinery plants, the ultra-wide design of automatic PVC roll up door accommodates oversized components such as jet engines and industrial turbines. Multi-layered sealing structures effectively isolate metal dust and cutting fluid mist generated during precision machining, maintaining cleanroom standards. For example, doors coated with polyurethane resist corrosion from cutting fluids, while electric roller shutter systems integrated with AGV navigation systems enable precise alignment between transport vehicles and doors, minimizing errors caused by manual intervention.
Logistics Warehouses
For storage facilities housing heavy machinery, containers, or industrial equipment, reinforced anti-collision designs are critical. Thick rubber edges and steel frames absorb impacts from forklifts traveling at high speeds, while wear-resistant sliding rails at the base minimize floor friction. In typhoon-prone coastal regions, doors are embedded with pre-installed wind cables anchored via ground anchors, enabling resistance to 12-level typhoons. Wind speed sensors automatically lower doors and activate hydraulic locking mechanisms during extreme weather.
Sports Stadiums
During international football matches or concerts, the rapid-opening capability of flexible high speed roll up door shortens crowd entry intervals. For instance, segment-folded door systems (50 meters wide) can fully open in 5 minutes to create evacuation pathways. Customizable surface printing with embedded LED light strips delivers dynamic visual effects during nighttime events. When closed, airtight seals integrated with negative pressure ventilation systems prevent rainwater ingress.
Exhibition Centers
For automotive or aerospace exhibitions, heavy-duty doors support direct entry of transport vehicles carrying large exhibits. Modular panel structures (each panel 3 meters wide) adapt to exhibition layouts. When closed, doors seamlessly integrate with architectural facades, while built-in anti-theft sensors monitor intrusions in real time. High-end venues employ electrochromic glass doors to adjust light transmission, balancing exhibit protection with natural illumination.
Specialized Functional Extensions
Industrial Factories: Integrated temperature/humidity control systems (e.g., mist humidifiers on door frames) prevent static electricity during transport of sensitive equipment.
Warehouses: RFID modules on doors sync with warehouse management systems to log goods in real time.
Stadiums: Flame-retardant aluminum door frames comply with fire safety codes; emergency detachable designs enable rapid access during rescue operations.
Exhibition Halls: Magnetic decorative panels allow quick reconfiguration for different themes.

With the tightening of global environmental protection policies and the awakening of consumers' health awareness, water-based epoxy floor paint is standing out from traditional floor coatings with its low VOC, non-toxic and environmentally friendly characteristics.
Policy dividends continue to be released
China's "dual carbon" goals and global environmental protection policies such as the EU REACH regulations force the paint industry to reduce VOC emissions. The VOC content of waterborne epoxy floor paint is only 1/10 of that of traditional solvent-based products, making it a key target of policy support.
Many places in China impose consumption taxes on high-pollution coatings (such as a tax rate of 4% for coatings with a VOC content of ＞420g/L), which further accelerates the replacement process of waterborne products.
Under the dual waves of smart cities and sustainable development, waterborne epoxy floor paint is no longer limited to ground protection, but has become an important carrier of intelligent and ecological building space. This article analyzes its future potential from the perspective of application scenario expansion and industrial chain collaboration.
"Breaking the Boundary" and Deepening of Application Scenarios
1.Supporting Upgrades of Industry 4.0
The high-voltage and anti-static requirements of smart factories for floors have spawned customized solutions. For example, semiconductor workshops use conductive waterborne epoxy paint, and the electrostatic dissipation efficiency reaches 10^6-10^9Ω, ensuring the safety of precision instruments.
In the field of warehousing and logistics, high wear-resistant coatings (hardness above 5H) are combined with AGV robot navigation systems to achieve seamless connection between floor functions and automated equipment.
2 .Green transformation of urban public spaces
Subway stations, hospitals and other places use anti-slip and antibacterial waterborne epoxy paint to reduce public safety accidents. In a renovation project of a tertiary hospital in Hangzhou, the construction period of water-based paint was shortened by 30%, and it can be put into use 7 days after the operation.
The commercial complex improves the aesthetics of the space through color customization (such as Morandi color system), and uses high-gloss topcoat to reduce lighting energy consumption, which meets the requirements of green building certification.
Industry chain collaboration: full-chain innovation from raw materials to services
1. Green revolution of upstream raw materials
Biological-based epoxy resin replaces petroleum-derived ingredients to reduce carbon footprint. The corn stalk extract-based resin developed by a certain company has a bio-based content of 30% and has been certified by the EU Ecolabel.
The addition of nanofillers (such as graphene) improves the thermal conductivity and UV resistance of the coating, extending the outdoor service life to more than 15 years.
2 .Digital transformation of downstream services
AR simulation technology is introduced on the construction end, and customers can preview the floor effect in real time and adjust the design plan to reduce the rework rate. A certain platform optimizes the material ratio through AI algorithm and reduces construction loss by 20%.
The operation and maintenance end relies on the Internet of Things platform to provide floor health monitoring and preventive maintenance services, forming a new "product + service" profit model.
Future challenges and strategic choices
1 .Balance between cost and performance
Price fluctuations of raw materials for water-based epoxy floor paint (such as epoxy resin) affect profit margins, and companies need to control costs through large-scale production and supply chain optimization.
In terms of performance, further improve weather resistance (such as -30℃ to 80℃ temperature difference adaptation) to expand outdoor applications49.
2. Standardization and brand internationalization
Domestic industry standards are not yet unified, and it is necessary to learn from European and American ASTM standards to establish a mandatory certification system to eliminate market chaos.
Brands going overseas need to break through technical barriers, such as entering the North American market through UL certification, or cooperating with local contractors to provide localized services.
