在濟南的街頭巷尾，舊卷簾門就像默默見證歲月變遷的 “時光守護者”。但隨著時間推移，風吹日曬、雨淋霜打，這些卷簾門難免 “容顏老去”，出現漆面剝落、銹跡斑斑、開關卡頓等問題。別擔心，掌握一套翻新秘籍，就能讓舊卷簾門實現 “逆齡重生”，重新為商鋪、倉庫等場所增添光彩。在濟南四季分明的氣候條件下，更要因地制宜，科學翻新，讓卷簾門煥發新活力。

　　On the streets and alleys of Jinan, old rolling shutter doors are like "guardians of time" silently witnessing the changes of time. But with the passage of time, exposure to wind, sun, rain, and frost, these rolling shutter doors are inevitably "aging in appearance", with problems such as paint peeling, rust stains, and lagging switches. Don't worry, mastering a set of renovation tips can help old rolling shutter doors achieve a "reverse aging rebirth" and add luster to places such as shops and warehouses. Under the distinct climate conditions of four seasons in Jinan, it is even more important to adapt to local conditions and carry out scientific renovations to bring new vitality to rolling shutter doors.

　　深度清潔，褪去歲月 “塵衣”：翻新的步，就是給舊卷簾門來一次徹底的清潔，去除表面的灰塵、污垢和老化涂層。濟南春季風沙較大，卷簾門表面往往附著大量沙塵，夏季雨水頻繁，還可能殘留水漬和泥污。先用高壓水槍或軟毛刷，配合中性清潔劑，對卷簾門表面進行初步沖洗和刷洗，將頑固污漬和灰塵清理干凈。對于油污較重的區域，可以使用專用的油污清洗劑，等待幾分鐘讓其充分溶解油污后，再用刷子刷洗。清潔完成后，用干凈的抹布或吹風機將卷簾門徹底擦干，確保表面無水分殘留。若卷簾門表面有貼紙、廣告殘留，可使用鏟刀小心鏟除，再用去膠劑去除殘留的膠水痕跡，讓卷簾門恢復干凈整潔的 “素顏”。

　　Deep cleaning, shedding the "dust coat" of time: The first step in renovation is to thoroughly clean the old rolling shutter door, removing surface dust, dirt, and aging coatings. Jinan has strong sandstorms in spring, and the surface of rolling shutter doors often adheres to a large amount of sand and dust. In summer, there is frequent rainfall, and there may be residual water stains and mud stains. First, use a high-pressure water gun or soft bristled brush, combined with a neutral cleaning agent, to preliminarily rinse and scrub the surface of the rolling shutter door, removing stubborn stains and dust. For areas with heavy oil stains, specialized oil cleaning agents can be used. Wait for a few minutes for the oil stains to fully dissolve before brushing with a brush. After cleaning, use a clean cloth or hair dryer to thoroughly dry the rolling shutter door, ensuring that there is no residual moisture on the surface. If there are stickers or advertising residues on the surface of the rolling shutter door, a scraper can be used to carefully remove them, and then a glue remover can be used to remove the remaining adhesive traces, restoring the rolling shutter door to a clean and tidy "bare face".

　　修復損傷，重塑堅固 “筋骨”：清潔完畢后，仔細檢查卷簾門的結構和表面，對發現的損傷進行修復。如果卷簾門存在變形問題，對于輕微變形，可以使用橡膠錘輕輕敲打矯正；若變形較為嚴重，則需要借助的矯正工具，如千斤頂等，緩慢施加外力使其恢復原狀。對于出現裂縫或孔洞的部位，可采用焊接的方式進行修補。選用與卷簾門材質相匹配的焊條，將裂縫或孔洞焊接牢固，焊接后使用角磨機將焊縫打磨平整，使其與周圍表面平齊。若卷簾門的導軌、滑輪等部件出現磨損、卡頓現象，要及時更換損壞的部件，并涂抹適量的潤滑油，保證卷簾門開關順暢。此外，檢查卷簾門的螺絲、鉚釘等固定件，如有松動或缺失，要及時擰緊或補齊，確保卷簾門結構穩固。

　　Repair damage and reshape sturdy "bones": After cleaning, carefully inspect the structure and surface of the rolling shutter door and repair any damages found. If there is a deformation problem with the rolling shutter door, for slight deformation, a rubber hammer can be used to gently tap and correct it; If the deformation is severe, professional correction tools such as jacks need to be used to slowly apply external force to restore it to its original state. For areas with cracks or holes, welding can be used for repair. Select welding rods that match the material of the rolling shutter door, weld the cracks or holes firmly, and use an angle grinder to polish the weld seam flat after welding, making it flush with the surrounding surface. If the guide rails, pulleys, and other components of the rolling shutter door are worn or stuck, the damaged parts should be replaced in a timely manner and an appropriate amount of lubricating oil should be applied to ensure smooth opening and closing of the rolling shutter door. In addition, check the screws, rivets and other fixing parts of the rolling shutter door. If they are loose or missing, they should be tightened or supplemented in a timely manner to ensure the stability of the rolling shutter door structure.

　　涂裝煥新，賦予亮麗 “新衣”：涂裝是讓舊卷簾門煥然一新的關鍵步驟。在濟南夏季高溫、冬季寒冷的環境下，選擇合適的涂料尤為重要。優先選用耐候性好、防腐防銹能力強的涂料，如丙烯酸漆、聚氨酯漆等。在涂裝前，為了增強涂料的附著力，可對卷簾門表面進行打磨處理，使用砂紙或打磨機將表面打磨粗糙，去除殘留的氧化層。打磨完成后，用干凈的抹布或吹風機將表面的灰塵清理干凈。涂裝時，可采用噴涂或刷涂的方式，噴涂效率高、涂層均勻，刷涂則更適合處理細節部位。一般需要涂裝 2 - 3 遍，每一遍涂裝都要等待前一遍涂料完全干燥后再進行，干燥時間根據涂料的特性和環境溫度而定。在濟南夏季高溫時，涂料干燥速度較快，可能幾小時就能干燥；而冬季低溫時，可能需要延長十幾小時甚更長時間。涂裝過程中，要注意保持涂層厚度均勻，避免出現流墜、漏涂等現象。待涂料完全干燥后，舊卷簾門就穿上了一件亮麗的 “新衣”，色彩鮮艷，質感如新。

　　Painting is a key step in revitalizing old rolling shutter doors, giving them a bright new look. Choosing the appropriate coating is particularly important in Jinan's hot summer and cold winter environment. Prioritize the use of coatings with good weather resistance and strong anti-corrosion and rust prevention capabilities, such as acrylic paint, polyurethane paint, etc. Before painting, in order to enhance the adhesion of the coating, the surface of the rolling shutter door can be polished by using sandpaper or a polishing machine to roughen the surface and remove residual oxide layer. After polishing, clean the surface dust with a clean cloth or hair dryer. When painting, spraying or brushing can be used, with high spraying efficiency and uniform coating, while brushing is more suitable for handling details. Generally, 2-3 coats of paint are required, and each coat should wait for the previous coat of paint to completely dry before proceeding. The drying time depends on the characteristics of the paint and the ambient temperature. During the high temperatures of summer in Jinan, the drying speed of coatings is relatively fast, and it may take a few hours to dry; In winter, when the temperature is low, it may need to be extended to more than ten hours or even longer. During the painting process, attention should be paid to maintaining uniform coating thickness and avoiding phenomena such as sagging and missed coating. After the paint is completely dry, the old rolling shutter door puts on a bright "new clothes" with bright colors and a texture like new.

　　細節完善，增添實用 “亮點”：除了外觀翻新，還可以對卷簾門的一些細節進行完善，提升其使用便利性和性。例如，為卷簾門安裝新的把手、鎖具，選擇款式新穎、質量可靠的產品，不僅方便開關門，還能增強防盜性能。在卷簾門底部加裝密封條，能有效阻擋灰塵、雨水進入室內，在濟南多風多雨的季節，這一舉措尤為實用。此外，還可以在卷簾門上添加個性化的裝飾元素，如彩繪、貼紙等，讓卷簾門更具特色，與商鋪風格相匹配，吸引顧客目光。

　　Refined details, adding practical "highlights": In addition to exterior renovation, some details of the rolling shutter door can also be improved to enhance its usability and safety. For example, installing new handles and locks for rolling shutter doors, choosing products with innovative styles and reliable quality, not only facilitates door opening and closing, but also enhances anti-theft performance. Installing a sealing strip at the bottom of the rolling shutter door can effectively prevent dust and rainwater from entering the room. This measure is particularly practical during the windy and rainy season in Jinan. In addition, personalized decorative elements such as paintings, stickers, etc. can be added to the rolling shutter door to make it more distinctive and match the style of the shop, attracting customers' attention.

　　只要按照清潔、修復、涂裝、完善細節這些步驟，就能讓濟南的舊卷簾門成功實現 “逆齡重生”。經過翻新的卷簾門，不僅外觀煥然一新，性能也得到提升，能夠繼續在歲月中堅守崗位，為建筑遮風擋雨，成為街頭一道亮麗的風景線。

　　As long as the steps of cleaning, repairing, painting, and perfecting details are followed, the old rolling shutter doors in Jinan can successfully achieve a "reverse aging rebirth". The renovated rolling shutter door not only has a brand new appearance, but its performance has also been improved. It can continue to hold its position in the years, providing shelter from wind and rain for buildings and becoming a beautiful scenery on the streets.
