Invisible screen window is a kind of screen window which can automatically rewind gauze. Mainly used for ventilation and mosquito prevention. The window frame is tightly attached to the window frame. When it is used, the gauze will be pulled down, and when it is not used, the gauze will be automatically rolled back into the gauze box. Does not occupy space, but also has strong sealing performance. Coordinate with high-end home improvement. Working principle of drum: gauze is collected through the drum. Opening mode: manual, electric and chain bead. Opening direction: vertical or horizontal. Working principle of folding: collect gauze through its folds (like an accordion). Some people like to use mosquito-repellent incense or electric mosquito-repellent incense, while others like to use spray. In any case, using invisible screen window is the most natural, healthy, environmentally friendly and economical way. Invisible screen window can not only prevent mosquitoes, but also prevent outdoor dust from entering the home, thus protecting our health. A certain amount of gauze is wound in a container by using a torsion spring roller shutter mechanism, which can be pulled out when in use and retracted when not in use, thus preventing mosquitoes and flies from entering and leaving, and is a beautiful and practical screen window.
Invisible screen window is not "invisible" in the true sense. The design principle of invisible screen window is only that the line diameter of the material is extremely thin (one thousandth of a millimeter) and the light transmittance is extremely high (96%). If you don't observe carefully, it seems that there are almost no screens: the materials that can be used to make invisible screens require high tensile strength, transparency, corrosion resistance, weather resistance, stability and low refractive index. Transparent monofilaments must be used. The weaving density is high, which can form the diffraction phenomenon of light and form "high-grade white". A chemical coating that increases light transmittance. Gauze can be rewound automatically.
