玻纤土工格栅的涂层工艺

        近年来,玻纤土工格栅在处治旧路面反射裂缝中得到大量的应用,采用沥青涂层玻纤土工格栅以改善其拉伸性能。采用配方均匀设计分析涂层液中沥青、 乳化剂和水的zui佳配比,采用正交试验分析涂层的zui佳工艺。玻纤土工格栅的原料为玻璃纤维，而玻璃纤维的强度较高,超过了其它纤维和金属。同时它的模量很高，具有很高的抗变形能力,断裂延伸率小于3%。

In recent years, the glass fiber geogrid has been widely used in the treatment of old pavement reflection cracks. The asphalt coated glass fiber geogrid is used to improve its tensile properties. The optimum ratio of asphalt, emulsifier and water in coating solution was analyzed by uniform formula design, and the optimum coating process was analyzed by orthogonal test. The material of glass fiber geogrid is glass fiber, and the strength of glass fiber is higher than other fibers and metals. At the same time, its modulus is very high, it has a high deformation resistance, and its fracture elongation is less than 3%.

       沥青涂层对玻璃长丝柬的断裂gq有非常显著的影响,涂层后,断裂gq约提高60% ;涂层的zui佳工艺:沥青、乳化剂、水配比为0. 198:0. 745:0. 057,烘焙温度为110 C ,烘焙时间为30 min。

Asphalt coating has a very significant effect on the breaking strength of glass filament Cambodia. After coating, the breaking strength is increased by about 60%. The best coating technology: asphalt, emulsifier, water ratio is 0.198:0.745:0.057, baking temperature is 110 C, baking time is 30 min.

        玻纤土工格栅是以玻纤无碱无捻粗纱为主要原料,采用一定的编织工艺制成的网状结构材料.玻纤土工格栅可以对沥青混合料起到物理改性作用,亦可有效地防止由基层引起的反射裂缝,是一种用于路面增强的优良土工合成材料,当前被广泛应用于沥青路面、水泥路面及机场跑道等工程项目中.然而，当前针对玻纤土工格栅的研究往往侧重于其力学性能,对其层间抗剪性能关注较少。

Glass fiber geogrid is a kind of reticular structure material which is made of glass fiber non alkali roving as the main raw material and certain weaving technology. Glass fiber geogrid can play a role in physical modification of asphalt mixture and effectively prevent reflection cracks caused by base course. It is a kind of excellent geosynthetic material used for road reinforcement, At present, it is widely used in asphalt pavement, cement pavement, airport runway and other engineering projects. However, the current research on the glass fiber geogrid is often focused on its mechanical properties, and less attention is paid to its interlayer shear resistance.

        玻纤土工格栅因其理化性能稳定、强度大、模量高、耐磨性和耐寒性优异、热稳定性好,并且可提高沥青混合料的承重能力,被广泛用于城市道路中。为保护玻纤和提高整体使用性能，以玻纤无碱无捻粗纱为主要原料,采用一定的编织工艺制成的网状结构材料,经过特殊的涂覆处理工艺而形成新型优良的土工基材一玻纤土工格栅。 在城市道路中使用玻璃格栅，综合造价低，养护维修费用低,社会效益明显,施工工艺容易掌握,具有很大的应用价值。加入玻纤土工格栅的沥青混凝土道路结构层,能有效地减小沥青混凝土结构层的设计厚度，从而降低工程成本;同时能延长道路使用年限，降低道路的维护费用及使用成本。

Glass fiber geogrid is widely used in urban roads because of its stable physical and chemical properties, high strength, high modulus, excellent wear resistance and cold resistance, good thermal stability, and can improve the bearing capacity of asphalt mixture. In order to protect the glass fiber and improve the overall performance, the glass fiber non alkali roving is used as the main raw material, and the mesh structure material is made by certain weaving process. After special coating process, a new excellent geotechnical base material - glass fiber geogrid is formed. The use of glass grid in urban roads has the advantages of low comprehensive cost, low maintenance cost, obvious social benefits, easy to master construction technology and great application value. The asphalt concrete road structure layer with glass fiber geogrid can effectively reduce the design thickness of the asphalt concrete structure layer, thus reducing the engineering cost; at the same time, it can extend the service life of the road, reduce the maintenance cost and use cost of the road.

       在高碱环境下玻璃纤维将遭到严重腐蚀。从腐蚀原理看,一般可以通过3种途径降低其腐蚀程度和速度，一是从玻璃纤维的化学成分人手提高格栅的耐碱性，如使用抗碱玻璃纤维;二是从玻璃纤维的涂层人手，阻止混凝土的碱性对格.栅的腐蚀;三是降低水泥基体的碱性。

Glass fiber will be severely corroded in high alkali environment. According to the corrosion principle, there are three ways to reduce the corrosion degree and speed. One is to improve the alkali resistance of the grid from the chemical composition of the glass fiber, such as using alkali resistant glass fiber; the other is to prevent the corrosion of the grid from the alkali of the concrete from the coating of the glass fiber; the third is to reduce the alkali of the cement matrix.

      不同的涂层胶种对坯布的强度提高和强度耐碱保留率均有一定影响，因此应该选择合适的涂层胶料来提高玻璃纤维格栅的抗碱性能。想先大家看完以上内容以后，应该也了解涂层工艺对玻纤土工格栅的影响了吧，希望会对大家有所帮助吧。

Different kinds of coating glue have certain influence on the strength improvement and strength alkali resistance retention of grey cloth. Therefore, it is necessary to select appropriate coating glue to improve the alkali resistance of glass fiber grid. After reading the above content, you should also understand the influence of coating process on fiberglass geogrid. I hope it will help you.
