一、      道路标线反光玻璃微珠

Reflectivity glass beads for road marking

反光型玻璃珠是道路标线涂料必备材料，主要用于道路标线，标志牌，护栏轮廓标识等。主要分为热熔涂料预混合型和施工面撒型两种。

Reflectivity glass beads as the necessary material for the road marked line, mainly used for road marked line, denoter, and identification for the guardrail out line. It divide into intermix glass beads, and drop on glass beads.

我公司产品除达到中国JT/T446-2001外，还可以生产符合英国BS6088-A标准，美国AASHO NO.Ⅰ标准和美国AASHO NO.Ⅱ标准，欧洲Drop ON Type EN 1423标准和Pre-MIX Type EN 1424标准，澳洲AS2009 B3.2标准，和韩国的ＫＳ标准。还可以根据用户需求提供850um(20目)-43um(325目)标准范围之间的不同粒径、不同配比的不同产品。

  Our company products was achieved the standard JT/T446-2001 of chine, we also can produce the products in according to the standard BS6088-A of England, AASHO NO.Ⅰand AASHO NO.Ⅱ of American, Drop ON Type EN 1423 and Pre-MIX Type EN 1424 of Europe,  AS2009 B3.2 of Australia and KS of Korea etc. At the same time, we also can supply from 850um(20mesh) to 43um(325mesh) different size, different proportion products according to the customer required

l       预混型 （Intermix glass beads）

在道路涂料生产过程中，将玻璃珠按照18-25%的重量比例（参照中国交通行业标准JT/T280-2004，不同国家和地区标准有所不同）混入涂料中，在涂料交付施工使用后，能够经历多次与车轮摩擦磨损也有反光性。按照中国国家标准GB/T24722-2009,此种玻璃珠的技术参数如下：

    During the production of marking paint, mix glass bead into paint based on the ratio of 18-25 %( weight percentage). After application of such kind of paint on road work, the paint still can keep reflectivity 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.

 Gravity: 2.4-2.6g/cm3

Size scope (μm)	Alternative NO.（mesh）	content（%）
>600	>30	0
600-300	30-50	50-90
300-150	50-100	5-50
<150	<100	0-5

Reflective index:≥1.50

Roundness:≥80

Content of magnetic particles:≤0.1%

Glass bead should be colorless, loosen

and spherical particle, and should be free

of cluster which can’t be loosen by slight impact.

l       面撒型（Drop On Glass Bead）

在涂料的施工的过程中，降热烙型涂料加热到一定温度铺在路面上来干时，随即撒入玻璃珠，增强标线的反光性能。

按照中国交通行业标注JT/T280-2004的规定，面撒玻璃珠的粒度分布如下，其他参数与内混型玻璃珠保持一致。

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 bead should be dropped on the surface of line white 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 bead is shown as table below, other parameters are the same with intermix glass bead.

Size scope   (μm)	Alternative NO.（mesh）	Content         （%）
>850	>20	0
850-600	20-30	5-30
600-300	30-50	30-80
300-106	50-140	10-40
<106	<140	0-5

 

二、      镀膜玻璃微珠( Coated glass beads)

我们生产普通玻璃微珠的前题下，还拥有镀膜技术，镀膜玻璃微珠是近年发展起来的  璃微珠新品种，用于道路标线面撒，显示了优良的特性，受到了广大用户的重视。我厂生产的镀膜玻璃珠主要分为防潮型镀膜玻璃微珠，粘结型镀膜玻璃微珠和双涂层镀膜玻璃微珠。

Except the normal glass beads, we are also have the technique to produce the coated glass beads. Coated glass beads is a kind of new products, which was grow up in recent year. With it widely used for road marking drop on, it’s fine features was showed, so now more and more end users pay attention to the coated glass beads. Our coated glass beads was mainly include moisture resistance coated glass beads, conglutination coated glass beads, and both coated glass beads.

l       防潮型镀膜玻璃微珠（ moisture resistance glass beads）

在玻璃微珠的生产过程中，将它的表面镀上一种特殊涂层，增强玻璃微珠的憎水性能。在下雨或者有雾的情况下，水滴不易沾附在玻璃微珠的表面，从而减轻恶劣天气对玻璃微珠反光效果的影响。同时这种玻璃微珠具有流动性好，不结块，播撒均匀，容易施工，保证反光效果，实用证明节省用量15％左右。

During the producing, make the special coated on the surface of the beads, to increased the moisture resistance. Under the rain or fog condition, the water difficult attached on the surface of the beads, so it will reduce the affect of the heavy weather influence the glass beads reflectivity ability. At the same time, this kinds of glass beads have perfect mobility, no blocking, uniform planting, construct easy, can guarantee reflectivity ability,  save dosage about 15%. 

l       粘结型镀膜玻璃微珠(Conglutination coated glass beads)

利用一种高性能的有机材料对玻璃珠进行外处理，玻璃珠经过镀膜处理后使用表面存在的强极性基变成非极性基，使得玻璃珠表面吸附空气中的灰尘现象减弱。由于镀膜珠含有特定的偶联剂，改善了微珠和涂料的粘结力能防止部分细小玻璃珠沉积到涂料中。玻璃珠镀膜处理后性能更加优越。

Used a kind of high performance organic materials to deal with the surface of the bead. After coated, the polar group of the bead surface changed to nonpolar, reduce the dust adsorption of the bead. Because of the coated bead contain the specific coupling agent, it improved the cohesive force between the beads and the paint, avoid some small beads deposit in to the paint. After coated the performance of the beads will be more superior.

l       双涂层镀膜玻璃微珠(Both coated glass beads)

此型号玻璃微珠是在普通玻璃微珠的加工过程中，将它的表面上分别镀上以上两种不同的涂层，提高玻璃微珠的防潮性能和与涂料的连结性能，从而延长玻璃微珠的使用寿命及其反光效果。

This type of beads was coated with the above two kinds of coating, increased the moisture resistance and conglutination ability, to extend the service life and increase the reflectivity ability of the beads.
