Container House Leakage Test

Container house leakage tests can be conducted through methods such as professional equipment spraying, pre-delivery water spray tests, and simulated rain tests. Details are as follows:

Spraying Operations by Professional Waterproof Testing Agencies

Shanghai Yuechang Container Technical Services Co., Ltd. has obtained a patent for a "container waterproof testing agency", which includes components such as wireless remote control devices, electric linear slide tables, support columns, and spray pipes. Staff members do not need to climb high; they can control the nozzle angle wirelessly on the ground through wireless remote control devices and wireless receiving circuits, rotating the nozzles to the left and right ends, front and back ends, and top of the container. They can also adjust the nozzle height within a certain range to perform water spray operations on these parts, thereby detecting whether the container house leaks. This brings convenience to staff while reducing the safety risks of falling from heights.

Pre-delivery Water Spray Tests

During the custom production of container houses by Zhongye Zhichuang, special attention is given to easily leaking positions such as roof welds, container body splicing seams, and areas around doors and windows. Multi-layer waterproofing techniques are used, combined with weather-resistant waterproof adhesives and waterproof membranes. A water spray test is conducted before delivery to inspect the waterproofing effect, ensuring that the container house has good waterproof performance before being put into use and avoiding leakage problems later on.

Simulated Rain Tests

For container energy storage cabinet battery compartments and the like, there are dedicated rain test chambers for waterproof testing. Taking IPX5 and IPX6 tests as examples, the IPX5 test uses a 6.3mm nozzle with a spray flow rate of 12.5 ± 0.625 L/min, a water pressure of 30 kPa, a spray distance of 2.5 - 3 m, and an adjustable angle of 0 - 60°. It performs full-coverage, dead-zone-free spraying on the top and four sides of the container, with a duration of no less than 1 minute per square meter. The IPX6 test uses a 12.5mm high-flow nozzle with a spray flow rate of 100 ± 5 L/min, a water pressure of 100 kPa, and the same spray distance, angle, and range as the IPX5 test, with a spray duration of no less than 1 minute per square meter to simulate continuous heavy rain conditions. After the test, if there is no water ingress, no accumulated condensation, normal insulation performance, and no water seepage at welds, sealing strips, wiring holes, etc., the test is considered qualified.
