Generally speaking, before professional technical inspection, it is possible to easily distinguish the quality of geotextiles by sensory appearance. A Geotextile of the same quality and same specification, color is white and material is not point, it is a good geotextile. In the same color, a geotextile with high needle compaction is also a good geotextile. The quality detection method of scientific research is the laboratory test, which can detect the burst super-strength index value, elongation index value, and CBR bursting super-strength index value of short-filament geotextile. From the test data information of the quality inspection report, compared with the performance parameters of the quality specification, it is possible to distinguish whether the quality of short-filament geotextile is required for civil construction. Short-filament geotextile has structural mechanics, good water absorption, corrosion resistance, anti-aging, protection, anti-filtration, drainage pipeline, maintenance, stiffness, reinforcement, and other functions.
There are many quality grades of short-filament geotextiles. Most manufacturers divide into four to five grades. However, no matter how they are distinguished, the following types of methods allow you to quickly distinguish the quality of geotextiles. Come and find out the bar!
1. Surface observation
By observing the surface layer of short-filament geotextile, people with work experience can usually understand the advantages and disadvantages of product quality. The color of the same quality raw material is pure milk white without any color casting. , so that it can be distinguished as a high-quality staple fiber geotextile.
2. Touch
In addition to observing appearance, people can distinguish and feel the firmness of raw materials using touch. Generally speaking, the mass of needles with relatively high relative density will be greater than that of low relative density, and the relative density of geotextile needles significantly endangers its quality problem.
3. Test identification
It is also possible to take a sample and send it to a laboratory for testing. According to the experiment, the laboratory can establish the expansion index value and its various main parameter specifications in the break of the product. Customers can make relative regulations about their engineering project work responsibilities based on the quality of this index, which is naturally passable. The product is also very clear.
Short-filament geotextiles are not hand-woven and have excellent water absorption, filterability, durability, and anti-corrosion properties. It is widely used in the basic construction of the architectural profession, so no matter the type or quality, it is a more solid support for the safety of engineering projects. Then according to the above methods, I strongly believe that you already have a deep understanding of the texture detection layer of geotextiles.
