Several Maintenance Points of PP Hood Cannot Be Ignored
PP fume hoods are an integral part of laboratory ventilation design. In order to prevent laboratory workers from inhaling or swallowing toxic, pathogenic, or toxic chemicals and organisms, the laboratory should have good ventilation. In order to prevent the absorption of some vapors, gases and particles (smoke, soot, dust and aerosols), the pollutants must be removed by means of fume hoods, hoods or partial ventilation.
The PP fume hood has a great improvement effect on the environment in the laboratory. Although the material of the fume hood is very innovative, we still need to consider the maintenance and other issues during the use. Then the biggest role of the fume hood is to eliminate harmful gases, so before installing the fume hood, we must consider whether the installation location is reasonable. Secondly, in order to prolong the service life of the fume hood, we also need to regularly clean and maintain the fume hood. The following Xiao Bian will introduce the four maintenance points that should not be overlooked when using laboratory fume hoods.
1. When the fume hood is in use, the operation window must be taken into account. Especially when conducting some chemical experiments, there are many harmful gases. Therefore, if the operation window is too small, some harmful gases will be spilled.
2. Next, the fume hoods often come into contact with various harmful gases during use. Therefore, we must regularly clean the fume hoods so that the surface of the fume hoods can be kept clean and harmful gases can be prevented from affecting the fume hoods.
3. After the fume hood is used, it must not be closed immediately because some of the harmful gases are still in the fume hood. If we suddenly shut down, these harmful gases will stay in the fume hood, not only the fume hood. Impact, but also may lead to the spillage of harmful gases, etc.
4. In the process of designing and processing the fume hood, its parts and components are very numerous. In order to ensure the normal operation of the fume hood, we must test and adjust the fume hood on a regular basis so that we can promptly find ventilation. Some problems occurred when the cabinet was used.
