卷簾門早起源于歐洲，八十年代開始在普及，由于它結構簡單，收放自如，既適合安裝在空間有限的私家車庫、店鋪，也適合安裝在大跨度、超挑高的工業廠房，因此無論在工作中還是生活中，到處都可以看到卷簾門的身影。

　　Rolling shutter doors originated in Europe and became popular in China in the 1980s. Due to their simple structure and easy retraction, they are suitable for installation in private garages, shopping malls, and shops with limited space, as well as in large-span and super tall industrial plants. Therefore, whether in work or life, rolling shutter doors can be seen everywhere.

　　產品多，品質上就容易出現良莠不齊。有人覺得卷簾門無非是早上開一次晚上關一次，需要什么技術含量，能出什么大問題？好，那么今天我就一次性將這些問題說個清楚。

　　When there are many products, it is easy to have uneven quality. Some people think that rolling shutter doors are nothing more than opening once in the morning and closing once at night. What technical content is required and what major problems can arise? Okay, then today I will clarify these questions all at once.

　　低頻啟閉的使用場景

　　Low frequency opening and closing usage scenarios

　　對于那些早上開一次晚上關一次的使用場景，如臨街商鋪，電動、遙控、速度這些就不用過多關注了，需要關注的是防盜性、保溫性和開關的流暢性等。

　　For usage scenarios where it is turned on once in the morning and turned off once at night, such as street facing shops, electric, remote control, speed, etc., there is no need to pay too much attention. What needs to be paid attention to are anti-theft, insulation, and smooth switching.

　　高強度

　　high strength

　　既然要防盜，簾板的強度要高，才不于輕易被暴力破壞。市場上常見的S235鋼板強度不夠，需得S550硬鋼鋼板，強度高一倍有余，應對一般破壞自然游刃有余。

　　Since we want to prevent theft, the strength of the curtain board should be high first, so as not to be easily damaged by violence. The commonly seen S235 steel plate in the market has insufficient strength and requires S550 hard steel plate, which has more than twice the strength and can handle general damage with ease.

　　可鎖閉

　　Lockable

　　其次，要能鎖閉，特別是一些商鋪等民用場所，一旦失竊會造成一定的經濟損失。單靠卷簾門自身的結構重力鎖閉還不夠，額外配備一道機械鎖，確保萬無一失。

　　Secondly, it should be able to be locked, especially in civilian places such as shops, as theft can cause certain economic losses. Relying solely on the structural gravity locking of the rolling shutter door is not enough. It is best to equip an additional mechanical lock to ensure foolproof safety.

　　保溫性

　　Thermal insulation

　　隆冬的寒冷、盛夏的炎熱都是對門保溫性的考驗，市面上的卷簾門多數采用單層鋼板，即便是雙層，厚度也多在10 mm 以內，內部簡單穿插些巖棉條而已。好的卷簾門厚度在 20 mm 左右，內部填充均勻致密的聚氨酯發泡保溫材料，保溫系數可達3.8 W/m2.K。無論冬天還是夏天都可以省下一筆不菲的暖氣空調費用。

　　The cold of winter and the hot of summer are tests of door insulation. Most rolling shutter doors on the market use single-layer steel plates, and even if they are double-layer, the thickness is mostly within 10mm, with simple rock wool strips interspersed inside. A good rolling shutter door has a thickness of about 20mm and is filled with evenly dense polyurethane foam insulation material, with an insulation coefficient of up to 3.8 W/m2. K. Whether in winter or summer, you can save a considerable amount of heating and air conditioning costs.

　　卷簾門簾板厚度約為22mm，內部填充聚氨酯發泡保溫材料

　　The thickness of the rolling shutter door curtain panel is about 22mm, and it is filled with polyurethane foam insulation material inside

　　從簾板的形狀上看，流線型設計比直線型更合理，因為弧形簾板條卷繞在一起時可以更加自然緊湊，相較于直線型截面簾板，不僅減少了邊角位置對簾板表面的摩擦，而且簾卷體積更小，所需的頂部安裝空間更小。

　　From the shape of the curtain panel, the streamlined design is more reasonable than the straight type, because the curved curtain Flat noodles can be more natural and compact when rolled together. Compared with the straight section curtain panel, it not only reduces the friction between the edge and corner positions on the surface of the curtain panel, but also reduces the volume of the curtain roll and requires less top installation space.

　　高頻啟閉的使用場景

　　High frequency opening and closing usage scenarios

　　對于使用相對頻繁的電動卷簾門來說，電控系統的限位準確性和保護是重要的兩個方面。

　　For electric rolling shutter doors that are used relatively frequently, the accuracy of the electronic control system's limit and safety protection are the two most important aspects.

　　限位準確

　　Accurate limit

　　一樘電動卷簾門，電機應該在門開到什么位置的時候停，不停會怎樣？門關到什么位置停，不停又會怎樣？

　　When should the motor of an electric rolling shutter door stop when the door is opened, and what happens if it doesn't stop? Where does the door stop and what happens if it doesn't stop?

　　從上圖可知，電動卷簾門是在電機帶動下將簾板卷繞在門軸上，如果門開到位置，電機沒有及時停住，就會將簾板從門框中強制甩出，繼而發生墜落傷人危險。

　　From the above figure, it can be seen that the electric rolling shutter door is driven by a motor to wrap the curtain plate around the door shaft. If the door is opened to the highest position and the motor does not stop in time, the curtain plate will be forcibly thrown out of the door frame, which may cause a risk of falling and injuring people.

　　如果門關到位置（地面），電機沒有立即停住，而是繼續帶動簾板向下，簾板則會逐級向下擠壓，導致門板變形，久而久之將無法正常關門。如下圖這樘門。

　　If the door is closed to the lowest position (on the ground), the motor does not immediately stop, but continues to drive the curtain downwards. The curtain will gradually press downwards, causing the door panel to deform and eventually unable to close properly. The door is shown in the picture below.

　　下限位不準導致卷簾門損壞嚴重

　　Inaccurate lower limit caused serious damage to the rolling shutter door

　　霍曼卷簾門電控系統配備的數字式編碼器，在安裝時可自動進行門簾啟停位置學習，位置精準，長時間使用后也不會跑偏，確保卷簾門啟閉正常。

　　The Hohmann rolling shutter door electrical control system is equipped with a professional digital encoder, which can automatically learn the opening and stopping position of the door curtain during installation. The position is precise and will not deviate after long-term use, ensuring the normal opening and closing of the rolling shutter door.

　　保護

　　safeguard

　　除此之外，卷簾門的性也不容忽視，比如門簾墜落的問題，卷人、壓人的問題等等，近年來時常見諸于報端。

　　In addition, the safety of rolling shutter doors cannot be ignored, such as the problem of falling door curtains, rolling and pressing people, etc., which have become common in newspapers in recent years.
