Due to the special nature of acrylic cold baths and the harsh operating environment, their construction must adhere to strict engineering standards to ensure structural stability, reliable function, safe use, and extended service life. Construction standards cover the entire process, from foundation preparation and installation techniques to sealing and protection, system commissioning, and acceptance. Each step must be based on material characteristics and the requirements of the cold therapy environment, forming a replicable and traceable quality assurance system.
In the foundation preparation stage, precise lines should be laid out according to the design drawings to confirm the flatness and load-bearing capacity of the ground where the cold bath will be placed. The ground must be waterproofed and leveled, and drainage slopes and collection ditches should be installed to prevent water leakage or retention that could damage the building structure. For large or irregularly shaped cold baths, a steel frame or concrete base must be prefabricated to ensure resistance to deformation under long-term loads. Buffer pads should be added at the contact points with the acrylic cylinder to avoid stress concentration caused by hard contact.
The installation process must emphasize the protection of the acrylic sheet and precise positioning. During transportation and hoisting, acrylic cylinder bodies should be slinged with flexible straps to prevent surface scratches or microcracks caused by excessive localized stress. When positioning, they should be aligned with the pre-set baseline, ensuring uniform gaps to avoid seal failure due to misalignment. Joints should preferably use welding rods or specialized adhesives of the same material. Before applying adhesive, ensure the joint surfaces are clean and dry, and control the ambient temperature and humidity to guarantee bonding strength and durability. Large components can be supplemented with mechanical fastening and structural adhesive composite connections to improve overall rigidity.
Sealing and protection are key control points during construction. All water contact surfaces and joints must use food-grade, low-temperature resistant, and mildew-proof sealing materials to ensure long-term watertightness and prevent detachment. Waterproof sleeves and redundant seals should be installed where electrical and refrigeration pipelines pass through the cylinder to prevent moisture intrusion and potential electrical safety hazards. The outer surface can be treated with an anti-UV coating to reduce the risk of photoaging and yellowing. During construction, the details of anti-slip surfaces and gentle slope edges should be completed simultaneously to improve safety.
System commissioning must be carried out after the main structure is completed and cleaned. The temperature control, circulation filtration, sterilization, and drainage systems should be started sequentially. The accuracy of water temperature maintenance, circulation flow rate, filtration efficiency, and the operating status of the sterilization device should be checked, and the consistency of sensor and actuator responses should be verified. Insulation and grounding tests should be performed on the electrical system to ensure compliance with safety standards for humid environments. Commissioning data should be recorded and archived as acceptance data.
The acceptance process should adhere to relevant national and industry standards, verifying structural stability, sealing, functional parameters, safety protection, and appearance quality item by item. Only after passing these checks can the system be put into use. Routine maintenance requires periodic checks of seals, electrical connections, and temperature control accuracy, and timely addressing of any potential hazards.
In summary, the acrylic cold bath construction standard is based on structural safety, aims for functional reliability, and guarantees protective durability. Through standardized operation throughout the entire process, the cold bath facility maintains stable performance and an excellent user experience in various application scenarios, providing a technical reference for industry quality improvement.
