　　反光型玻璃珠是道路標線涂料必備材料，主要用于道路標線，標志牌，護欄輪廓標識等。主要分為熱熔涂料預混合型和施工面撒型兩種。

　　我公司產品除達到中國JT/T446-2001外，還可以生產符合英國BS6088-A標準和英國BS6088-B標準，美國AASHO NO.I標準和美國AASHO NO.II標準，歐洲Drop ON Type EN 1423標準和Pre-MIX Type EN 1424標準，澳洲AS2009-B標準和澳洲AS2009-C標準，和韓國的KSL2521標準。還可以根據用戶需求提供850um（20目）-45um（325目）標準范圍之間的不同粒徑、不同配比的不同產品。

　　Reflective glass beads as the necessary material for the road marking line, mainly used for road marking line, denoter, and identification for the guardrail out line. It is divided into intermix glass beads, and drop on glass beads.

　　Our company products have achieved the standard JT/T446-2001 of china, we can also produce the products in according to the standard BS6088-A of England and BS6088-B of England, AASHO NO. I and AASHO NO. II of American, Drop ON Type EN 1423 and Pre-MIX Type EN 1424 of Europe, AS2009-B and AS2009-C of Australia and KSL2521 of Korea etc. At the same time, we can also supply from 850um（20mesh） to 45um（325mesh） different size, different proportion products according to the customer request.

　　預混型

　　在道路涂料生產過程中，將玻璃珠按照18-25%的重量比例（參照中國交通行業標準JT/T280-2004，不同國家和地區標準有所不同）混入涂料中，在涂料交付施工使用后，能夠經歷多次與車輪磨擦磨損也有反光性。按照中國國家標準GB/T24722-2009，此種玻璃珠的技術參數如下：

　　Intermix glass beads

　　During the production of marking paint, mix glass beads with paint based on the ratio of 18-25 %（ weight percentage）。 After application of such kind of paint on road work, the paint can still keep reflective after wear and friction of car wheels. The ratio is referring to the standard of Communication Industry Standard of People's Republic of China No.JT/T280-2004. Standards will be different in countries and areas.

　　According to the specification of Communication Industry Standard of People's Republic of China No.JT/T446-2001, the granulometry is shown as table below.

　　玻璃珠的比重：2.4-2.6g/cm3磁性顆粒含量：≤0.1%

　　Gravity: 2.4-2.6 g/cm3Content of magnetic particles: ≤0.1%

　　玻璃珠折射率：≥1.50  Reflective index: ≥1.50要求玻璃珠整體外觀為無色，松散球狀顆粒，清潔無雜質，不含有經輕度沖擊仍不崩散的結塊物。

　　玻璃珠的圓度：≥80% Roundness: ≥80%Glass beads should be colorless, loose and spherical particle, and should be free of cluster which can' t be loosen by slight impact.

　　面撒型

　　在涂料的施工的過程中，將熱熔型涂料加熱到一定溫度鋪在路面上未干時，隨即撒入玻璃珠，增強標線的反光性能。

　　Drop On Glass Beads

　　During the application of paint on road work, thermoplastic paint should be to a certain level and used on the road surface as marking line, drop on glass beads should be dropped on the surface of line while it is still wet to increase the reflectivity of road marking line.

　　According to the specification of Standard of Ministry of Transport of the People's Republic of China No. GB/T24772-2009, the granulometry of drop on glass beads are shown as table below, other parameters are the same as intermix glass bead.
