一、什么是反光膜

反(fan)光(guang)(guang)膜，是利用(yong)光(guang)(guang)學原(yuan)理，能把光(guang)(guang)線(xian)逆反(fan)射回到光(guang)(guang)源處(chu)的一種(zhong)(zhong)反(fan)光(guang)(guang)材(cai)(cai)(cai)料(liao)，是應用(yong)最為廣(guang)(guang)泛(fan)的一種(zhong)(zhong)逆反(fan)射材(cai)(cai)(cai)料(liao)，主要(yao)利用(yong)玻(bo)璃(li)珠技(ji)術(shu)，微(wei)(wei)棱(leng)鏡技(ji)術(shu)、合成樹脂技(ji)術(shu)，薄膜技(ji)術(shu)和(he)涂敷技(ji)術(shu)和(he)微(wei)(wei)復(fu)制(zhi)(zhi)技(ji)術(shu)制(zhi)(zhi)成，廣(guang)(guang)泛(fan)應用(yong)于交通領域，其顏色鮮亮，夜間可以反(fan)光(guang)(guang)，從而(er)起到警示作(zuo)用(yong)。一般反(fan)光(guang)(guang)膜主要(yao)采用(yong)聚合物材(cai)(cai)(cai)料(liao)制(zhi)(zhi)成，常(chang)見(jian)的有PET、PC、PMMA、PVC四種(zhong)(zhong)材(cai)(cai)(cai)質，不同材(cai)(cai)(cai)質的反(fan)光(guang)(guang)膜在性能和(he)使用(yong)壽命方面有所差別。

二、反光膜多少錢一平方

一般來說，反光膜有Ⅰ到Ⅶ類七個等級，不同等級的反光膜價格有所不同，除此之外，反光膜價格還會受到其顏色圖案、尺寸規格、生產廠家、材質做工等因素的影響，一般在80~120元/㎡左右，如果需要特殊定制印字、貼字的話，價格可能更高，具體價格要咨詢商家。反光膜作為反光材料，在很多地方都可以買到，像五金店、建材市場、部分汽車用品店都有賣的，也可以網購；如果購買量比較大的話，建議聯系專門的反光膜生產廠家采購，批量采購價格會優惠一些，注意選擇好的反光膜品牌購(gou)買(mai)，購(gou)買(mai)時還(huan)可以通過看(kan)(kan)材質(zhi)、看(kan)(kan)亮度(du)、看(kan)(kan)厚度(du)、聞味道等(deng)方法判斷(duan)反光膜(mo)的質(zhi)量。

三、反光膜分類與級別

反(fan)(fan)(fan)(fan)光(guang)膜(mo)(mo)(mo)的(de)(de)分類(lei)方法有(you)很多，其中比較普遍接受(shou)的(de)(de)分類(lei)原則，是以逆反(fan)(fan)(fan)(fan)射單元的(de)(de)基(ji)本(ben)結(jie)構(gou)(gou)(gou)為(wei)(wei)(wei)(wei)(wei)基(ji)礎，根據反(fan)(fan)(fan)(fan)光(guang)膜(mo)(mo)(mo)正面(mian)光(guang)度性(xing)(xing)能的(de)(de)逆反(fan)(fan)(fan)(fan)射系數高(gao)低(di)為(wei)(wei)(wei)(wei)(wei)主的(de)(de)排序方法，按照《道路交(jiao)(jiao)(jiao)通(tong)(tong)(tong)(tong)反(fan)(fan)(fan)(fan)光(guang)膜(mo)(mo)(mo)》（GB/T 18833-2012）的(de)(de)規(gui)定，反(fan)(fan)(fan)(fan)光(guang)膜(mo)(mo)(mo)按照其光(guang)度性(xing)(xing)結(jie)構(gou)(gou)(gou)和(he)(he)(he)用(yong)(yong)途，分為(wei)(wei)(wei)(wei)(wei)7種類(lei)型(xing)(xing)：1、I類(lei)：通(tong)(tong)(tong)(tong)常為(wei)(wei)(wei)(wei)(wei)透鏡埋入式(shi)玻(bo)璃(li)珠(zhu)(zhu)型(xing)(xing)結(jie)構(gou)(gou)(gou)，稱(cheng)工程級反(fan)(fan)(fan)(fan)光(guang)膜(mo)(mo)(mo)，使用(yong)(yong)壽(shou)(shou)(shou)命一般(ban)(ban)為(wei)(wei)(wei)(wei)(wei)7年(nian)，可(ke)用(yong)(yong)于永久(jiu)性(xing)(xing)交(jiao)(jiao)(jiao)通(tong)(tong)(tong)(tong)標志(zhi)(zhi)和(he)(he)(he)作(zuo)(zuo)業(ye)(ye)(ye)(ye)區(qu)(qu)設施(shi)(shi)。2、II類(lei)：通(tong)(tong)(tong)(tong)常為(wei)(wei)(wei)(wei)(wei)透鏡埋入式(shi)玻(bo)璃(li)珠(zhu)(zhu)型(xing)(xing)結(jie)構(gou)(gou)(gou)，稱(cheng)超工程級反(fan)(fan)(fan)(fan)光(guang)膜(mo)(mo)(mo)，使用(yong)(yong)壽(shou)(shou)(shou)命一般(ban)(ban)為(wei)(wei)(wei)(wei)(wei)10年(nian)，可(ke)用(yong)(yong)于耐久(jiu)性(xing)(xing)交(jiao)(jiao)(jiao)通(tong)(tong)(tong)(tong)標志(zhi)(zhi)惡化作(zuo)(zuo)業(ye)(ye)(ye)(ye)區(qu)(qu)設施(shi)(shi)。3、III類(lei)：通(tong)(tong)(tong)(tong)常為(wei)(wei)(wei)(wei)(wei)密封膠囊式(shi)玻(bo)璃(li)珠(zhu)(zhu)型(xing)(xing)結(jie)構(gou)(gou)(gou)，稱(cheng)高(gao)強(qiang)級反(fan)(fan)(fan)(fan)光(guang)膜(mo)(mo)(mo)，使用(yong)(yong)壽(shou)(shou)(shou)命一般(ban)(ban)為(wei)(wei)(wei)(wei)(wei)10年(nian)，可(ke)用(yong)(yong)于永久(jiu)性(xing)(xing)交(jiao)(jiao)(jiao)通(tong)(tong)(tong)(tong)標志(zhi)(zhi)和(he)(he)(he)作(zuo)(zuo)業(ye)(ye)(ye)(ye)區(qu)(qu)設施(shi)(shi)。4、IV類(lei)：通(tong)(tong)(tong)(tong)常為(wei)(wei)(wei)(wei)(wei)微(wei)棱(leng)鏡結(jie)構(gou)(gou)(gou)，稱(cheng)超強(qiang)級反(fan)(fan)(fan)(fan)光(guang)膜(mo)(mo)(mo)，使用(yong)(yong)壽(shou)(shou)(shou)命一般(ban)(ban)為(wei)(wei)(wei)(wei)(wei)10年(nian)，可(ke)用(yong)(yong)于永久(jiu)性(xing)(xing)交(jiao)(jiao)(jiao)通(tong)(tong)(tong)(tong)標志(zhi)(zhi)、作(zuo)(zuo)業(ye)(ye)(ye)(ye)區(qu)(qu)設施(shi)(shi)和(he)(he)(he)輪(lun)(lun)廓(kuo)標。5、V類(lei)：通(tong)(tong)(tong)(tong)常為(wei)(wei)(wei)(wei)(wei)微(wei)棱(leng)鏡結(jie)構(gou)(gou)(gou)，稱(cheng)大角度反(fan)(fan)(fan)(fan)光(guang)膜(mo)(mo)(mo)，使用(yong)(yong)壽(shou)(shou)(shou)命一般(ban)(ban)為(wei)(wei)(wei)(wei)(wei)10年(nian)，可(ke)用(yong)(yong)于永久(jiu)性(xing)(xing)交(jiao)(jiao)(jiao)通(tong)(tong)(tong)(tong)標志(zhi)(zhi)、作(zuo)(zuo)業(ye)(ye)(ye)(ye)區(qu)(qu)設施(shi)(shi)和(he)(he)(he)輪(lun)(lun)廓(kuo)標。6、VI類(lei)：通(tong)(tong)(tong)(tong)常為(wei)(wei)(wei)(wei)(wei)微(wei)棱(leng)鏡結(jie)構(gou)(gou)(gou)，有(you)金屬鍍(du)層(ceng)，使用(yong)(yong)壽(shou)(shou)(shou)命一般(ban)(ban)為(wei)(wei)(wei)(wei)(wei)3年(nian)，可(ke)用(yong)(yong)于輪(lun)(lun)廓(kuo)標和(he)(he)(he)交(jiao)(jiao)(jiao)通(tong)(tong)(tong)(tong)柱，無金屬鍍(du)層(ceng)時也可(ke)用(yong)(yong)于作(zuo)(zuo)業(ye)(ye)(ye)(ye)區(qu)(qu)設施(shi)(shi)和(he)(he)(he)字符較少的(de)(de)交(jiao)(jiao)(jiao)通(tong)(tong)(tong)(tong)標志(zhi)(zhi)。7、VII類(lei)：通(tong)(tong)(tong)(tong)常為(wei)(wei)(wei)(wei)(wei)微(wei)棱(leng)鏡結(jie)構(gou)(gou)(gou)，柔性(xing)(xing)材質、使用(yong)(yong)壽(shou)(shou)(shou)命一般(ban)(ban)為(wei)(wei)(wei)(wei)(wei)3年(nian)，可(ke)用(yong)(yong)于臨時性(xing)(xing)交(jiao)(jiao)(jiao)通(tong)(tong)(tong)(tong)標志(zhi)(zhi)和(he)(he)(he)作(zuo)(zuo)業(ye)(ye)(ye)(ye)區(qu)(qu)設施(shi)(shi)。

四、反光膜的作用

反(fan)(fan)(fan)光(guang)(guang)膜(mo)(mo)是現代交(jiao)通工程中(zhong)常(chang)用(yong)(yong)的一種材(cai)料，具有良好(hao)的反(fan)(fan)(fan)光(guang)(guang)效果，用(yong)(yong)于制(zhi)作各類(lei)反(fan)(fan)(fan)光(guang)(guang)標志標牌(pai)(pai)、車輛號(hao)(hao)牌(pai)(pai)及(ji)安全(quan)設施等(deng)。反(fan)(fan)(fan)光(guang)(guang)膜(mo)(mo)顏色(se)鮮(xian)亮(liang)，在晚上(shang)或是燈光(guang)(guang)不足的情況下，反(fan)(fan)(fan)光(guang)(guang)膜(mo)(mo)能利(li)用(yong)(yong)其反(fan)(fan)(fan)光(guang)(guang)效果將光(guang)(guang)線反(fan)(fan)(fan)射(she)回來，提高在夜間(jian)和惡劣天氣下行車者(zhe)對交(jiao)通標志牌(pai)(pai)的識(shi)別度，讓人(ren)們更容易(yi)看到警(jing)示牌(pai)(pai)，從而起到警(jing)示作用(yong)(yong)，預防事(shi)故發生。除了(le)公(gong)路交(jiao)通標志牌(pai)(pai)上(shang)常(chang)見以外，在汽車車牌(pai)(pai)上(shang)、車身標識(shi)上(shang)、廠區指(zhi)(zhi)示系統、路牌(pai)(pai)、門(men)牌(pai)(pai)號(hao)(hao)、廣告(gao)標識(shi)、公(gong)益(yi)指(zhi)(zhi)示牌(pai)(pai)等(deng)方面也(ye)比較常(chang)見。
