The sand and dust test chamber simulates the natural sandstorm environment through built-in dust, and tests the IP5X and IP6X dustproof performance of the product casing.
During normal use, we will find that the talcum powder in the sand and dust test box is lumpy and damp. In this case, we need to turn on the heating device to fully dry the talcum powder before normal use. However, talcum powder also has a service life. Under normal circumstances, the talcum powder needs to be replaced after 20 reuses.
How to correctly replace the talcum powder in the sand and dust test box?
Several steps:
1. Open the door of the sand and dust test box, use a brush to clean all the talcum powder in the inner box, and sweep it to the bottom of the inner box. Pay attention to the talcum powder on the door, screen, sample power supply, vacuum tube, etc. to be cleaned.
2. Open the cover on the left side of the sand and dust test box, place a box at the bottom of the cone to hold the used talcum powder, and then use a large wrench to open the bolts at the bottom of the sand and dust test box, and tap the bottom so that all the talcum powder can fall into the box.
3. Tighten the bottom bolts, close the cover on the left side of the sand and dust test box, and pour 2 kg of new talcum powder into the inner box of the sand and dust test box to complete the work of replacing talcum powder.
Pay special attention when using the sand and dust test box. After the dust is generated, please let it stand for half an hour to allow the talcum powder to fall freely before opening the box door to take out the sample.
