一、什么是反光膜
反(fan)(fan)光(guang)(guang)膜(mo)(mo),是利用(yong)光(guang)(guang)學原理,能(neng)把光(guang)(guang)線逆反(fan)(fan)射回到光(guang)(guang)源處的一(yi)種反(fan)(fan)光(guang)(guang)材(cai)料(liao),是應用(yong)最為(wei)廣(guang)(guang)泛的一(yi)種逆反(fan)(fan)射材(cai)料(liao),主(zhu)要利用(yong)玻璃珠(zhu)技(ji)術,微(wei)棱鏡技(ji)術、合(he)成樹脂技(ji)術,薄膜(mo)(mo)技(ji)術和涂敷技(ji)術和微(wei)復制(zhi)技(ji)術制(zhi)成,廣(guang)(guang)泛應用(yong)于交通領(ling)域,其(qi)顏色(se)鮮亮(liang),夜間可(ke)以反(fan)(fan)光(guang)(guang),從而起到警示作用(yong)。一(yi)般反(fan)(fan)光(guang)(guang)膜(mo)(mo)主(zhu)要采用(yong)聚合(he)物材(cai)料(liao)制(zhi)成,常(chang)見的有PET、PC、PMMA、PVC四種材(cai)質,不同材(cai)質的反(fan)(fan)光(guang)(guang)膜(mo)(mo)在性能(neng)和使用(yong)壽命方面(mian)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買(mai),購買(mai)時還(huan)可以通過看(kan)(kan)材(cai)質、看(kan)(kan)亮度、看(kan)(kan)厚度、聞味(wei)道等方法(fa)判斷反光膜的質量。
三、反光膜分類與級別
反(fan)(fan)(fan)光(guang)(guang)膜的(de)(de)(de)分類(lei)方(fang)法有很多,其中比較普遍(bian)接(jie)受的(de)(de)(de)分類(lei)原(yuan)則,是以(yi)逆反(fan)(fan)(fan)射(she)單元(yuan)的(de)(de)(de)基本結構(gou)(gou)為(wei)(wei)(wei)(wei)(wei)(wei)基礎,根據反(fan)(fan)(fan)光(guang)(guang)膜正面光(guang)(guang)度性(xing)(xing)能的(de)(de)(de)逆反(fan)(fan)(fan)射(she)系(xi)數高(gao)低(di)為(wei)(wei)(wei)(wei)(wei)(wei)主(zhu)的(de)(de)(de)排序方(fang)法,按照(zhao)《道路交(jiao)通(tong)(tong)(tong)(tong)反(fan)(fan)(fan)光(guang)(guang)膜》(GB/T 18833-2012)的(de)(de)(de)規定(ding),反(fan)(fan)(fan)光(guang)(guang)膜按照(zhao)其光(guang)(guang)度性(xing)(xing)結構(gou)(gou)和用(yong)(yong)(yong)(yong)(yong)(yong)途,分為(wei)(wei)(wei)(wei)(wei)(wei)7種類(lei)型(xing)(xing):1、I類(lei):通(tong)(tong)(tong)(tong)常(chang)(chang)為(wei)(wei)(wei)(wei)(wei)(wei)透(tou)鏡(jing)(jing)埋入式玻璃珠(zhu)型(xing)(xing)結構(gou)(gou),稱工程級反(fan)(fan)(fan)光(guang)(guang)膜,使用(yong)(yong)(yong)(yong)(yong)(yong)壽(shou)命(ming)一(yi)(yi)般為(wei)(wei)(wei)(wei)(wei)(wei)7年(nian),可(ke)(ke)用(yong)(yong)(yong)(yong)(yong)(yong)于(yu)(yu)永(yong)久(jiu)性(xing)(xing)交(jiao)通(tong)(tong)(tong)(tong)標(biao)(biao)(biao)志(zhi)和作(zuo)(zuo)業區(qu)設(she)(she)施(shi)(shi)。2、II類(lei):通(tong)(tong)(tong)(tong)常(chang)(chang)為(wei)(wei)(wei)(wei)(wei)(wei)透(tou)鏡(jing)(jing)埋入式玻璃珠(zhu)型(xing)(xing)結構(gou)(gou),稱超工程級反(fan)(fan)(fan)光(guang)(guang)膜,使用(yong)(yong)(yong)(yong)(yong)(yong)壽(shou)命(ming)一(yi)(yi)般為(wei)(wei)(wei)(wei)(wei)(wei)10年(nian),可(ke)(ke)用(yong)(yong)(yong)(yong)(yong)(yong)于(yu)(yu)耐久(jiu)性(xing)(xing)交(jiao)通(tong)(tong)(tong)(tong)標(biao)(biao)(biao)志(zhi)惡化作(zuo)(zuo)業區(qu)設(she)(she)施(shi)(shi)。3、III類(lei):通(tong)(tong)(tong)(tong)常(chang)(chang)為(wei)(wei)(wei)(wei)(wei)(wei)密封膠囊式玻璃珠(zhu)型(xing)(xing)結構(gou)(gou),稱高(gao)強級反(fan)(fan)(fan)光(guang)(guang)膜,使用(yong)(yong)(yong)(yong)(yong)(yong)壽(shou)命(ming)一(yi)(yi)般為(wei)(wei)(wei)(wei)(wei)(wei)10年(nian),可(ke)(ke)用(yong)(yong)(yong)(yong)(yong)(yong)于(yu)(yu)永(yong)久(jiu)性(xing)(xing)交(jiao)通(tong)(tong)(tong)(tong)標(biao)(biao)(biao)志(zhi)和作(zuo)(zuo)業區(qu)設(she)(she)施(shi)(shi)。4、IV類(lei):通(tong)(tong)(tong)(tong)常(chang)(chang)為(wei)(wei)(wei)(wei)(wei)(wei)微棱鏡(jing)(jing)結構(gou)(gou),稱超強級反(fan)(fan)(fan)光(guang)(guang)膜,使用(yong)(yong)(yong)(yong)(yong)(yong)壽(shou)命(ming)一(yi)(yi)般為(wei)(wei)(wei)(wei)(wei)(wei)10年(nian),可(ke)(ke)用(yong)(yong)(yong)(yong)(yong)(yong)于(yu)(yu)永(yong)久(jiu)性(xing)(xing)交(jiao)通(tong)(tong)(tong)(tong)標(biao)(biao)(biao)志(zhi)、作(zuo)(zuo)業區(qu)設(she)(she)施(shi)(shi)和輪廓(kuo)標(biao)(biao)(biao)。5、V類(lei):通(tong)(tong)(tong)(tong)常(chang)(chang)為(wei)(wei)(wei)(wei)(wei)(wei)微棱鏡(jing)(jing)結構(gou)(gou),稱大角度反(fan)(fan)(fan)光(guang)(guang)膜,使用(yong)(yong)(yong)(yong)(yong)(yong)壽(shou)命(ming)一(yi)(yi)般為(wei)(wei)(wei)(wei)(wei)(wei)10年(nian),可(ke)(ke)用(yong)(yong)(yong)(yong)(yong)(yong)于(yu)(yu)永(yong)久(jiu)性(xing)(xing)交(jiao)通(tong)(tong)(tong)(tong)標(biao)(biao)(biao)志(zhi)、作(zuo)(zuo)業區(qu)設(she)(she)施(shi)(shi)和輪廓(kuo)標(biao)(biao)(biao)。6、VI類(lei):通(tong)(tong)(tong)(tong)常(chang)(chang)為(wei)(wei)(wei)(wei)(wei)(wei)微棱鏡(jing)(jing)結構(gou)(gou),有金(jin)屬(shu)鍍(du)層(ceng),使用(yong)(yong)(yong)(yong)(yong)(yong)壽(shou)命(ming)一(yi)(yi)般為(wei)(wei)(wei)(wei)(wei)(wei)3年(nian),可(ke)(ke)用(yong)(yong)(yong)(yong)(yong)(yong)于(yu)(yu)輪廓(kuo)標(biao)(biao)(biao)和交(jiao)通(tong)(tong)(tong)(tong)柱,無金(jin)屬(shu)鍍(du)層(ceng)時(shi)也可(ke)(ke)用(yong)(yong)(yong)(yong)(yong)(yong)于(yu)(yu)作(zuo)(zuo)業區(qu)設(she)(she)施(shi)(shi)和字符較少的(de)(de)(de)交(jiao)通(tong)(tong)(tong)(tong)標(biao)(biao)(biao)志(zhi)。7、VII類(lei):通(tong)(tong)(tong)(tong)常(chang)(chang)為(wei)(wei)(wei)(wei)(wei)(wei)微棱鏡(jing)(jing)結構(gou)(gou),柔性(xing)(xing)材質(zhi)、使用(yong)(yong)(yong)(yong)(yong)(yong)壽(shou)命(ming)一(yi)(yi)般為(wei)(wei)(wei)(wei)(wei)(wei)3年(nian),可(ke)(ke)用(yong)(yong)(yong)(yong)(yong)(yong)于(yu)(yu)臨時(shi)性(xing)(xing)交(jiao)通(tong)(tong)(tong)(tong)標(biao)(biao)(biao)志(zhi)和作(zuo)(zuo)業區(qu)設(she)(she)施(shi)(shi)。
四、反光膜的作用
反(fan)光膜是現(xian)代交(jiao)通工程(cheng)中(zhong)常(chang)(chang)用(yong)的(de)(de)一(yi)種材料(liao),具有良好的(de)(de)反(fan)光效果,用(yong)于制作各類反(fan)光標(biao)志標(biao)牌(pai)、車(che)(che)輛號牌(pai)及安(an)全設施(shi)等。反(fan)光膜顏色鮮亮,在(zai)晚上或是燈光不(bu)足的(de)(de)情況下(xia),反(fan)光膜能利用(yong)其反(fan)光效果將光線反(fan)射回來,提高(gao)在(zai)夜間和(he)惡劣天氣下(xia)行(xing)車(che)(che)者對交(jiao)通標(biao)志牌(pai)的(de)(de)識別度,讓人們更容易看到(dao)警(jing)(jing)示(shi)(shi)牌(pai),從而起到(dao)警(jing)(jing)示(shi)(shi)作用(yong),預防事故發生(sheng)。除了公路(lu)交(jiao)通標(biao)志牌(pai)上常(chang)(chang)見以外,在(zai)汽(qi)車(che)(che)車(che)(che)牌(pai)上、車(che)(che)身(shen)標(biao)識上、廠區(qu)指(zhi)示(shi)(shi)系統、路(lu)牌(pai)、門牌(pai)號、廣告標(biao)識、公益指(zhi)示(shi)(shi)牌(pai)等方面也比較常(chang)(chang)見。
