Leak proof trays (also known as spill proof trays, liquid receiving trays, or leak containment trays) are critical equipment used in industrial, laboratory, medical, and storage environments to prevent liquid leakage and contamination. Its core function is to contain leaked liquids and prevent diffusion, so capacity design is one of the key parameters to pay attention to when selecting trays. This article will systematically sort out the capacity classification, selection criteria, and typical application scenarios of anti leakage trays to help users make reasonable selections.
1、 Common classification of anti leakage tray capacity
According to the requirements of different application scenarios, the capacity of anti leakage trays is usually divided into the following categories:
Small tray (20-50 liters)
Applicable scenarios: laboratory countertops, under small equipment, and at the bottom of chemical reagent storage racks.
Features: Compact in size, easy to move, suitable for handling trace leaks or temporarily placing small containers (such as reagent bottles, oil pots).
Example: A leak proof tray used in the laboratory to place a separating funnel and prevent experimental liquids from dripping.
Features: Balancing capacity and flexibility, it can accommodate liquids with large single leakage volumes (such as engine oil and coolant).
Example: A tray used in a 4S car dealership to hold and repair vehicle oil leaks to prevent ground contamination.
Large pallets (200-500 liters and above)
Applicable scenarios: Chemical plant storage tank area, oil depot, and base area of large mechanical equipment.
Features: Large capacity, sturdy structure, capable of handling sudden large-scale leaks or long-term storage of multiple hazardous liquid containers.
Example: A chemical enterprise uses a leak proof tray set to store multiple 200 liter chemical drums, meeting the compliance requirements for hazardous chemical storage.
2、 Key influencing factors of capacity design
The capacity of the anti leakage tray is not an isolated parameter and needs to be comprehensively considered in conjunction with the following factors:
Volume and quantity of storage containers
The tray capacity should be able to accommodate at least 110% of the maximum capacity of the storage container (if storing a 200 liter oil drum, the tray capacity needs to be ≥ 220 liters) to cope with accidental overturning or leakage. High risk scenarios with leakage risk level (such as highly corrosive liquids) require the selection of trays with larger capacity to avoid liquid overflow and secondary accidents.
Tray structure and material
Large capacity pallets are usually made of high-density polyethylene (HDPE) or steel, and reinforced with ribs to improve load-bearing capacity.
Some trays support multi-layer stacking or combination expansion (such as modular splicing), flexibly adapting to different needs.
Considering extreme conditions (such as external water inflow caused by rainstorm), the capacity needs to be increased by 20% -30%.
The capacity selection of anti leakage trays needs to balance actual needs, safety redundancy, and cost efficiency. Small pallets are suitable for precise control of leaks, while large pallets are the "safety cornerstone" for hazardous chemical storage. Users should choose trays with suitable capacity based on the specific liquid type, container specifications, and regulatory requirements of the scene. If necessary, they can consult professional suppliers for customized design to achieve a win-win situation of safety and economy.
