結構與設計影響透光效果

　　Structure and design affect the transparency effect

　　（一）傳統卷軸式結構

　　（1） Traditional scroll structure

　　傳統的卷軸式卷簾門在關閉狀態下，門板緊密貼合，若采用不透光材質，如金屬門板，幾乎完全阻擋光線。但即便使用透光材質，由于卷軸式卷簾門在卷動過程中，門板之間會存在一定的縫隙，這些縫隙會導致光線的不均勻透過，在地面或墻面上形成光影條紋，影響整體的透光均勻性。而且，隨著使用時間的增加，門板之間的縫隙可能會因磨損而變大，進一步降低透光效果。

　　Traditional roller shutter doors have tightly fitted door panels when closed. If opaque materials such as metal door panels are used, they almost completely block light. But even if transparent materials are used, there will be certain gaps between the door panels during the rolling process of the roller shutter door, which will cause uneven light transmission and form light and shadow stripes on the ground or wall, affecting the overall uniformity of light transmission. Moreover, as the usage time increases, the gaps between the door panels may become larger due to wear, further reducing the light transmission effect. 

　　（二）折疊式結構

　　（2） Folding structure

　　折疊式卷簾門在打開和關閉過程中，門板以折疊的方式收納或展開。這種結構在關閉時，門板之間的連接相對松散，即使采用透光材質，也會因為縫隙較大而使得光線透過率不穩定。不過，其優勢在于可以根據實際需求靈活調整打開的程度，當需要更多光線進入時，可以將卷簾門部分打開，讓光線從折疊縫隙中透入，從而在一定程度上滿足對光線的需求。

　　Folding roller shutter doors are stored or unfolded in a folded manner during the opening and closing process. When this structure is closed, the connection between the door panels is relatively loose, and even if transparent materials are used, the light transmittance will be unstable due to large gaps. However, its advantage lies in the ability to flexibly adjust the degree of opening according to actual needs. When more light is needed to enter, the rolling shutter door can be partially opened to allow light to pass through the folding gap, thus meeting the demand for light to a certain extent. 

　　（三）特殊設計的卷簾門

　　（3） Specially designed rolling shutter doors

　　一些具有特殊設計的卷簾門在透光性上有獨特表現。例如，帶有百葉窗設計的卷簾門，通過調整百葉的角度，可以控制光線的進入量和方向。當百葉完全打開時，能夠實現較大程度的透光；而當百葉關閉時，則可以阻擋光線，同時還能保證一定的通風效果。還有一些卷簾門在門板上設置了透明視窗，這些視窗可以讓使用者在不打開卷簾門的情況下觀察外部情況，同時也能增加光線的進入，適用于對性和透光性都有一定要求的場所，如便利店、小型倉庫等。

　　Some specially designed rolling shutter doors have unique performance in terms of transparency. For example, a rolling shutter door with a louver design can control the amount and direction of light entering by adjusting the angle of the louvers. When the blinds are fully opened, a greater degree of light transmission can be achieved; When the blinds are closed, they can block light while ensuring a certain ventilation effect. Some rolling shutter doors are equipped with transparent windows on the door panel, which allow users to observe the external situation without opening the rolling shutter door, and also increase the entry of light. They are suitable for places that have certain requirements for safety and transparency, such as convenience stores, small warehouses, etc.

　　材質決定透光基礎

　　The material determines the transparency foundation

　　（一）金屬材質卷簾門

　　（1） Metal material rolling shutter door

　　金屬材質是卷簾門常用的材料之一，如不銹鋼、鋁合金等。以不銹鋼卷簾門為例，其表面光滑堅硬，具有良好的防盜、防火性能，但由于金屬本身的不透明特性，這類卷簾門幾乎完全不透光。在濟南的倉儲物流中心、車庫以及對防護要求較高的商鋪中，不銹鋼卷簾門被廣泛應用，它在為場所提供保障的同時，也完全隔絕了光線，滿足了內部空間對私密性和避光性的需求。

　　Metal materials are one of the most commonly used materials for rolling shutter doors, such as stainless steel, aluminum alloy, etc. Taking stainless steel rolling shutter doors as an example, their surface is smooth and hard, with good anti-theft and fireproof performance. However, due to the opaque nature of the metal itself, these rolling shutter doors are almost completely opaque. Stainless steel rolling shutter doors are widely used in storage and logistics centers, garages, and shops with high security requirements in Jinan. While providing security for the venue, they also completely isolate light and meet the needs of privacy and light avoidance in internal spaces. 

　　鋁合金卷簾門雖然質量較輕，且具有一定的耐腐蝕性能，但同樣不具備透光性。不過，部分鋁合金卷簾門會在門板上進行特殊處理，例如采用鏤空雕花設計，這種設計在一定程度上增加了美觀性，但由于鏤空部分較小且主要作用并非透光，所以整體的透光效果依然微乎其微，僅能透過少量散射光線，無法滿足對光線有較高需求的場景。

　　Although aluminum alloy rolling shutter doors are lightweight and have certain corrosion resistance, they also do not have transparency. However, some aluminum alloy rolling shutter doors will undergo special treatment on the door panel, such as using hollow carved designs, which to some extent increase aesthetics. However, due to the small size of the hollow parts and their main function not being light transmission, the overall light transmission effect is still minimal, only able to transmit a small amount of scattered light, and cannot meet the high demand for light in scenes. 

　　（二）塑料材質卷簾門

　　（2） Plastic material rolling shutter door

　　塑料材質的卷簾門在透光性上與金屬材質形成鮮明對比。聚碳酸酯（PC）材質的卷簾門是典型代表，它具有極高的透光率，可達 89% 左右，近乎于玻璃的透光效果，能夠讓大量光線透過，使室內保持明亮。在濟南的一些花卉市場、蔬果等場所，PC 材質的卷簾門十分常見，商家利用其透光特性，既能保證店鋪在關閉狀態下仍有一定的光線展示商品，又能起到防護作用，同時還能營造出通透、整潔的視覺效果，吸引顧客目光。

　　Plastic roller shutter doors form a sharp contrast with metal materials in terms of transparency. Polycarbonate (PC) material roller shutter doors are a typical representative, with extremely high light transmittance of about 89%, almost the same as glass, which can allow a large amount of light to pass through and keep the interior bright. In some flower markets, vegetable and fruit supermarkets and other places in Jinan, PC material rolling shutter doors are very common. Merchants use their light transmission characteristics to ensure that the store still has a certain amount of light to display products even when it is closed, while also playing a protective role. At the same time, they can create a transparent and clean visual effect, attracting customers' attention. 

　　此外，PVC 材質的卷簾門也具有一定的透光性，不過相較于 PC 材質，其透光率略低，大約在 60%-70% 之間。這種卷簾門通常用于對透光需求不是特別高的場所，如小型商鋪、倉庫出入口等，它在保證一定光線進入的同時，還具備良好的柔韌性和防水性，能夠適應濟南多變的天氣環境。

　　In addition, PVC material roller shutter doors also have a certain degree of transparency, but compared to PC material, their transparency is slightly lower, about 60% -70%. This type of rolling shutter door is usually used in places where the demand for light transmission is not particularly high, such as small shops, warehouse entrances, etc. It not only ensures a certain amount of light enters, but also has good flexibility and waterproofness, which can adapt to the changing weather environment in Jinan.
