| 先看一下旧规范（GB/T 18833-2002）中是如何“分级“的： Look at the "classification" in the old specification (GB/T 18833-2002). 1、反光膜按其不同的逆反射原理，可分为玻璃珠型和微棱镜型两类。 1, the reflective film can be divided into two types: glass bead type and microprism type according to their different reverse reflection principle. 2、 反光膜按其不同的结构，可分为棱镜埋入型、密封胶囊型和微棱镜型三类。 2, the reflective film can be divided into three types, which are prism burying, sealed capsule and micro prism according to their different structures. 3、反 光膜按其不同的你反射性能，可分为五个等级：一级反光膜为微棱镜型反光膜；二级反光膜为密封胶囊型反光膜，通常称高强级反光膜；三级反光膜为透镜埋入型反光膜，通常称超工程级反光膜；四级反光膜为透镜埋入型反光膜，通常称工程级反光膜；五级反光膜为透镜埋入型反光膜，通常称经济级反光膜。 3, according to the different reflective film your reflection performance, can be divided into five levels: a reflective film for micro prism type reflective film; two reflective film is a sealed capsule type reflective film, usually called high-strength reflecting film; three grade reflective film for lens embedded type reflective film, usually called super engineering reflective film; four grade reflective film for lens embedded type reflective film, usually called engineering grade reflective film; five grade reflective film for lens embedded type reflective film, usually called economic grade reflective film. 再来看一下新规范（GB/T 18833-2012）中是如何“分类“的： Look at the "classification" in the new specification (GB/T 18833-2012). 1、 一类——通常为透镜埋入式玻璃珠型结构，称工程级反光膜，使用寿命一般为7年，可用于永久性交通标志和作业区设施。（即类似原国标中的四级七年工程级反光膜，例如：国产通明TM7600系列工程膜、日本NCI EG-7系列等，原国标要求的四级反光膜耐候性是五年）。 1, a class -- usually lens embedded glass bead structure, called engineering reflective film, the service life is usually 7 years, it can be used for permanent traffic signs and operation area facilities. It is similar to the four grade and seven grade engineering reflective film in the original national standard, for example, the homemade TM7600 series engineering film and Japan NCI EG-7 series. The four grade reflective film required by the original national standard is weatherproof for five years. 另外，新国标一类膜与原国标四级膜的主要区别是： In addition, the main difference between the new national standard and the four grade membrane of the original national standard is: a）增加了橙色、灰色两个颜色； A) added orange and gray two colors; b）反光性要求改变：将观测角由原来的0.2°、0.33°、1°改0.2°、0.5°、1°，在个别颜色个别角度上上降低了反光性能要求（例如白色），目的是强调了反光膜的广角性、大角度性； B) the change of reflectivity requires that the viewing angle should be changed from 0.2 degrees, 0.33 degrees, 1 degrees to 0.2 degrees, 0.5 degrees, 1 degrees, and the reflective performance requirements (such as white) should be reduced on the individual angles of individual colors. The purpose is to emphasize the wide angle and large angle of reflective films. c）明确提出一类膜的使用寿命为七年，耐候性检测中的光度（逆反射系数）最大衰减度仍为不低于标准值的50%。 C) clearly proposed that the service life of a class of films is seven years, and the maximum attenuation of the photometric (reverse reflection coefficient) in the weatherability detection is still not less than 50% of the standard value. 2、二类——通常为透镜埋入式玻璃珠型结构，称超工程级反光膜，使用寿命一般为10年，可用于永久性交通标志和作业区设施。（即类似原国标三级反光膜，例如：国产通明TM7800系列、日本NCI SEG18000系列等）。另外，新国标二类膜与原国标三级膜的主要区别是： The 2 and the two category -- usually lens embedded glass bead structure, is called super engineering reflective film, the service life is generally 10 years, it can be used for permanent traffic signs and operation area facilities. (that is, similar to the original national standard three reflective film, for example: the homemade TM7800 series, the Japanese NCI SEG18000 series, etc.). In addition, the main differences between the two types of the new national standard and the original national standard three are: a）增加了橙色； A) added orange; b）观测角也将原来的0.33°改为0.5°，反光性能要求基本未变； B) the observation angle also changed the original 0.33 degrees to 0.5 degrees, and the performance of the reflective light was basically unchanged. c）明确提出二类膜的使用寿命为十年，耐候性检测中的光度（逆反射系数）最大衰减度为不低于标准值的65%，原国标为80%，要求有所降低。 C) clearly pointed out that the service life of the two kinds of membranes is ten years, and the maximum attenuation degree of photometry (inverse reflectance coefficient) is not less than 65% of the standard value, and the original national standard is 80%, which requires a reduction. 3、三类——通常为密封胶囊式玻璃珠型结构，称高强级反光膜，使用寿命一般为10年，可用于永久性交通标志和作业区设施。（即类似原国标二级反光膜，例如：国产通明TM1800系列、日本NCI F800系列等）。另外，新国标三类膜与原国标二级高强级膜的主要区别是： The 3 and the three category -- usually sealed capsule glass bead structure, is called high strength reflective film, the service life is generally 10 years, it can be used for permanent traffic signs and operation area facilities. (that is, similar to the original national standard two reflective film, for example: the homemade TM1800 series, the Japanese NCI F800 series, etc.). In addition, the main difference between the new national standard three kinds of film and the two grade high strength grade film of the original national standard is: a）增加了橙、灰、荧光黄绿、荧光黄、荧光橙五色； A) added orange, ash, fluorescent yellow green, fluorescent yellow, fluorescent orange five colors; b）观测角也将原来的0.33°改为0.5°，反光性能要求有一定程度的提高，特别是广角性方面； B) the observation angle also changed the original 0.33 degrees to 0.5 degrees, and the performance of the reflective light was improved to a certain extent, especially in the aspect of wide angle. c）明确提出三类膜的使用寿命为十年，耐候性检测中的光度（逆反射系数）最大衰减度仍为不低于标准值的80%，要求没变。 C) clearly pointed out that the service life of the three kinds of membranes is ten years, and the maximum attenuation degree of photometry (inverse reflectance coefficient) is still no less than 80% of the standard value. 4、四类——通常为微棱镜型结构，称超强级反光膜，使用寿命一般为10年，可用于永久性交通标志、作业区设施和轮廓标。（即类似原国标二级反光膜，例如：美国3M 超强级3930系列、美国艾利特强级T-6500系列、城市高强级T-3500系列、日本 NCI水晶级R600系列等）。 The 4 and four class -- usually micro prism structure, is called super strong reflective film. Its service life is generally 10 years, and it can be used for permanent traffic signs, operation area facilities and contour labels. (that is similar to the original two GB reflective film, for example: the United States 3M super 3930 series, T-6500 series, the American elite level city high strength grade T-3500 series, Japan NCI crystal R600 series etc.). 另外，新国标四类膜与原国标二级膜的主要区别是： In addition, the main differences between the four types of the new national standard and the original national standard two are: a）增加了橙、灰、荧光黄绿、荧光黄、荧光橙五色； A) added orange, ash, fluorescent yellow green, fluorescent yellow, fluorescent orange five colors; b）观测角也将原来的0.33°改为0.5°，强调广角性。这个类别是新增加的，与高强膜明确区分开，所以反光性能要求提高很大； B) the observation angle also changed the original 0.33 degrees to 0.5 degrees, emphasizing the wide angle. This category is newly added and is clearly separated from the high-strength film, so the performance of the reflective light is greatly improved. c）明确提出四类膜的使用寿命为十年，耐候性检测中的光度（逆反射系数）最大衰减度仍为不低于标准值的80%，要求没变。 C) clearly pointed out that the service life of the four kinds of membranes is ten years, and the maximum attenuation degree of photometry (inverse reflectance coefficient) is still no less than 80% of the standard value. 5、五类——通常为微棱镜型结构，大角度反光性能好，称大角度反光膜，使用寿命一般为10年，可用于永久性交通标志、作业区设施和轮廓标。（即类似原国标一级反光膜，例如：美国3M 钻石级4090系列、美国艾利星光级T-7500系列、智能全棱镜膜T-11500系列等）。 The 5 and the five type -- usually micro prism type structure, have large reflectivity and large angle reflective film. The service life is generally 10 years, which can be used for permanent traffic signs, operation area facilities and contour labels. (that is similar to the original national grade reflective film, such as: the United States 3M diamond 4090 series, American avery starlight T-7500 series, T-11500 series intelligent prism film etc.). 另外，新国标五类膜与原国标一级膜的主要区别是： In addition, the main difference between the five types of the new national standard and the primary film of the original national standard is: a）增加了橙、荧光黄绿、荧光黄、荧光橙四色； A) added orange, fluorescent yellow green, fluorescent yellow, fluorescent orange four colors; b）观测角也将原来的0.33°改为0.5°，并增加了1°的检测，强调广角性，对小角度的光度要求有所降低，对大角度的光度要求有所提高； B) the observation angle also changed from 0.33 degrees to 0.5 degrees, and increased by 1 degrees. The emphasis is wide angle, which reduces the photometric requirement for small angle and improves the photometric requirement for large angle. c）明确提出四类膜的使用寿命为十年，耐候性检测中的光度（逆反射系数）最大衰减度仍为不低于标准值的80%，要求没变。 C) clearly pointed out that the service life of the four kinds of membranes is ten years, and the maximum attenuation degree of photometry (inverse reflectance coefficient) is still no less than 80% of the standard value. 6、六类——这类膜是原国标中没有的，通常为有金属镀层的微棱镜结构，薄且软，易卷曲，防水性很好，光度性能很高，主要用于交通器材上，如警示柱、轮廓标等，也可作为施工区临时标志使用。该类反光膜的反光性很高，使用寿命较短，一般为3年，耐候性检测中的光度（逆反 6, six - this type of film is not the original standard, usually for micro prism structure, a metal coating Bo Qieruan, easy to curl, good waterproof performance, high luminosity, mainly used for transportation equipment, such as warning column, contour standard, also can be used as temporary signs used in construction area. The reflectivity of this kind of reflective film is very high, and the service life is shorter. It is generally 3 years, and the luminosity in the weather resistance detection is inverse. |
