At the same time should pay attention to see the gauze screens, frames, bearings, springs and other materials. Poor-quality glass fiber gauze can only withstand a few thousand push-pulls, while plastic gauze is easy to expand and contract, with a high probability of deformation. It is recommended to purchase high-quality chemical fiber gauze as much as possible. This type of gauze can be pushed and pulled tens of thousands times without friction. The screen frame should not be too thin, because if it is less than 1.0mm, it may be deformed in five to six months, which will affect the normal use. If the open bearing enters the dust, the operation will be unfavorable, and it is better to choose a fully closed silent bearing. Screen springs are generally not visible. You can use hand-pulling to see the rewinding effect before buying. If the rewinding is too loose, do not buy it.
