The shell is entirely made of 1 mm cold-rolled steel plate, and the cabinet base is made of 2.0 mm cold-rolled steel plate. The inner and outer surfaces are coated with acid washed phosphating epoxy resin powder and subjected to baking and curing treatment.
The inner liner of the fireproof chemical cabinet (upper, lower, left, and right inner lining panels) is all made of porcelain white PP (polypropylene resin) board; On the right side of the cabinet bottom, there is a PP adjustable air inlet with a PP adjustable air valve; The bottom layer inside the cabinet has a landfill chamber (leakage tank) that can store no less than 120 mm thick yellow sand, used for burying flammable materials such as metallic sodium and yellow phosphorus (white phosphorus). The baffle should be connected to the cabinet as a whole; The bottom of the cabinet is equipped with four mobile Silent nylon wheels with a diameter of 50 mm, which facilitates the movement of flammable and toxic materials storage cabinets; The front wheel has two manually adjustable levers, which facilitate the positioning of flammable and toxic storage cabinets.
The fireproof chemical cabinet is equipped with three three-layer stepped PP resin movable shelves, which are made of corrosion-resistant porcelain white PP and have 10 mm ventilation holes.
Fireproof material: The chemical safety cabinet is filled with ceramic fibers, a fireproof material with insulation and heat preservation properties. It is lightweight, heat-resistant, and has excellent thermal stability, making it non-toxic and environmentally friendly.
Hinge: Seamless piano hinge, ensuring that the door can open 180 degrees. Fireproof expansion seals should be installed between the cabinet door and the cabinet, and the seals should comply with the requirements of GB 16807-2009. (An environmentally friendly thermal expansion sealing strip should be installed between the cabinet door and the cabinet. When the temperature is between 150–180 ℃, the sealing strip will expand locally, and when the temperature reaches 750 ℃, the sealing strip will expand completely. The expansion ratio is 1:5 to ensure the safety of stored drugs.)
The top of the chemical safety cabinet has a detachable function for easy maintenance and repair.
Mechanical locks: Install magnetic locks, mechanical password locks, and other mechanical locks on the storage cabinet. The confidentiality performance of locks should comply with the standard requirements of "Security and Prevention Requirements for Storage Places of Explosive Hazardous Chemicals" (GA 1511-2018). (Mechanical anti-theft locks should comply with the standard of GA/T 73).
7-inch LCD touch screen microcomputer control system, real-time temperature and humidity environmental monitoring, fan monitoring, VOC concentration environmental monitoring system, and integrated alarm system.
Temperature and humidity digital display setting and measurement value, high-precision sensor, and immediate alarm prompt when the temperature and humidity inside the cabinet exceed the set measurement value.
PSC fan imported from the United States, with a current of 24 volts, stable performance, ultra quiet, and no spark or static electricity.
Efficient filtration system, arranged and distributed according to particle size, following ASTM standards, effectively targeting acidic and organic gases, with strong adsorption capacity. For particle filters, high-efficiency HEPA filters are used, achieving a filtration efficiency of 99.995% for particles larger than 0.3um.
Special security requirements: The mechanical lock key and electronic password lock password should be kept separately by two people, and both people should be present when opening.
7-inch large screen display, IoT intelligent HMI human-machine interface, resolution: 1024×600, perfect visual system;
Supports SIM card 4G communication, and the 4G communication module has a national mandatory product certification certificate;
With chemical management function, it can manage the inventory list of chemicals and support the display of no less than 100 types of chemical lists, including serial numbers, chemical names, quantities, units, etc; Inventory addition, deletion, and modification can be performed on the device side; Data synchronization to cloud backend servers; The WeChat client can view the current inventory list.
Through the WeChat client, remote management can be carried out, and historical VOC data, temperature and humidity environmental data can be viewed and presented in a curved manner; Historical alarm records can be viewed, and fans and alarm lights can be remotely controlled.
API interfaces can be provided to support third-party platform docking functionality.
The software control system has received a test report from the China Software Evaluation Center.
