Question 2: What is the definition, material and function of geotextile? Geotextile is a new building material, and its raw materials are synthetic fibers of high molecular polymers such as polyester, polypropylene, acrylic fiber and nylon. According to the manufacturing method, it can be divided into woven geotextile and nonwoven geotextile. Nonwoven geotextiles are mainly used in general engineering. Geotextiles have many functions such as filtration, filtration, isolation, reinforcement, protection and sealing.
Question 3: What material is geotextile made of? According to the manufacturing method, it can be divided into woven geotextile and nonwoven geotextile. The varieties are divided into filament and short silk, and the main raw material is polyester yarn.
Question 4: What are the raw materials for maintaining geotextiles? What is polyester staple fiber made of? For maintenance, the requirements are generally not high, and the low price is not standard. Huazhi geotechnical material
Manufacturer's answer
Question 5: What is the geotextile for concrete curing? I probably understand what you mean by planting flowers and plants on it. Dexiang nonwoven geotextile can be used. I hope I can help you!
Question 6: What material is used to weave geotextiles? There are several kinds of geotextiles, long filament spunbonded needle-punched nonwoven geotextiles, as the name implies, are made of silk; Short fiber needle-punched nonwoven geotextile, made of the fibers used;
Question 7: How to use the raw materials of needle-punched nonwoven geotextile, and how many kinds are there? What specifications and raw materials are used. I really need it. Thank you. There are polyester short silk, polyester filament, polypropylene geotextile and filament woven geotextile. Our company specializes in producing geotextile, geomembrane and other geotechnical materials, and has a professional construction welding team. I wish you success!
Question 8: What are the specifications of geotextiles? Some people say that geotextile is a geotextile made of chemical materials. This statement has a certain foundation. It is a water-permeable or waterproof synthetic building material woven by crochet. The specifications of geotextiles we see are all rolled up with plastic sheets. The width is about five to six meters, and the length can be cut at will. In local specialty shops, it is generally 50 meters or 100 meters. Geotextiles can be divided into non-woven fabrics. The geotextile we are familiar with can not only seep and drain water, but also be used as a material for flood control dams. Used in sand control, sewage treatment and port use, it has the advantages of light weight, mild stretching, high temperature resistance, high service strength and long service life.
The geotextile produced by the manufacturer must have the material certificate of the national method before it can be applied in the construction process. The raw materials produced by geotextile are an important part of its forming performance, so manufacturers must show the performance and characteristic indexes of raw materials and the formal specifications and standards of geotextile when selling. After the construction team has formulated the commercial products of geotextile, it will also take a certain number of products to relevant departments for inspection, and put them into use only after all the data are qualified.
Before laying geotextile, the construction team must have made a detailed construction organization design, recorded and marked the construction position, methods and technical skills of geotextile specifications. In the process of laying, if the area is small, manual work can be used, but manual work must use flat shoes throughout the laying process to prevent the whole plane from being trampled. The whole paved plane should be tamped as many meters as it needs to be laid, and the construction of protective layer should complement each other to ensure the splicing of the whole project is foolproof. Another important link in the construction process is the upper and lower anchorage. After completion, the next construction operation can only be carried out after the acceptance of the supervisor and the appraisal of the relevant departments. During the inspection, the supervisor shall test all butt joints by inflation method, and check whether the air pressure rises or falls by vacuum gauge. If it rises, it is necessary to find out the cause of air leakage and rectify it in time. Finally, it is necessary to remind the construction personnel that the position of the joint cannot be selected at the crack mouth, otherwise the quality of the joint will be completely unqualified during quality inspection.
Question 9: What are the names of geotextiles? Polyester filament geotextile is also called filament nonwoven geotextile, polyester nonwoven geotextile, long filament spunbonded needle-punched geotextile and filament infiltrated geotextile; According to the purpose, it can also be called water permeable geotextile, and when combined with polyethylene for waterproofing, it can also be called-waterproof geotextile. The technical index of general waterproof geotextile only calculates the strength of cloth, ignoring the strength of membrane! National standard of waterproof geotextile (composite geomembrane) GB/T 17642- 1998. The technical parameters are the same! !
Woven filament geotextile, also known as woven filament geotextile or woven geotextile, can be divided into polypropylene woven fabric, polyester woven fabric and other fiber woven fabrics according to the different fibers used. The production process of woven fabric is similar to that of cotton spinning, but there are higher requirements for seam in construction-the national standard requires that the seam strength should not be less than 50% of the fabric strength, and the thread used for seam should have the same anti-corrosion and anti-aging effect as polyester or polypropylene fiber, and cotton ordinary fiber is not allowed to be used instead, which is very important for construction quality.
