First ancestor
Fixed screens---Fixed screens are actually the old-fashioned screens we used in small homes, and the four-frame intermediate yarn. Its advantage is that it is durable and durable. Nowadays, many old houses still use such screens, which are still sought after by many old users. Nowadays, there are still such screens on the market.
Its shortcoming is that it looks old from the appearance, it is not suitable for those new buildings, it should be unloaded when it is not used in winter, and the lighting effect is not very good. At present, there are many such screens on the market, which are not mainstream. Products, some outdated, but affordable, and relying on its solid structure are also favored by some consumers.
Evolutionary level
Magnetic strip screens---The so-called soft magnetic strip screens are attached with magnetic strips around the window frame. Magnetic strips are also placed around the gauze. When used, the gauze is sucked on the window frame. When not in use, the yarn is used. The net was taken down, and this screen window was very sought after in the past few years. Although it is more robust and sealed than the invisible screens on the market today, the lighting is not convenient, and it cannot be folded when stored, and requires a large storage space. Another fatal weakness is that the life of the magnetic strip is limited. The magnetic strip is usually replaced once every three years. If the yarn is broken, it needs to be replaced with the magnetic strip. The cost per fan is 30-40 yuan. .
Sublimation
Invisible screens (rolling screens) are currently popular in the market for screens. Generally, invisible screens can adjust the spring force inside the yarn box. Some yarn boxes can be removed to reduce the force, and some can also automatically remove the dust. It has been suggested that such new screens are prone to be bad, because you are ordering inferior invisible screens, and the universal invisible screens are very mature.
Folding screens---There have been folding screens on the market these years, and the folding screens are more beautiful because they are folded like fans. Mosquitoes may enter from folding screens more than invisible screens. Moreover, the windproof effect of the folding screen window is not good, and the invisible screen window screen can make a fuss in the track to ensure a certain wind resistance, but the folding type is more difficult. The biggest disadvantage of the folding screen window is that the gauze is damp and exposed to the sun. After the fold, I can't take it back, and the rope is also broken. Therefore, it is recommended that you do not use folding screens.
