Geosynthetic materials are a collective term for various products made from synthetic materials used in geotechnical and civil engineering construction. Because they are mainly used in geotechnical engineering, they are named "geosynthetic materials" after the word "geo" to distinguish them from natural materials. Testing scope: polyester staple fiber needle punched nonwoven geotextile, filament spunbonded nonwoven geotextile, staple fiber heat set nonwoven geotextile, filament machine woven geotextile, woven geotextile, composite reinforced geotextile Mechanical and mechanical properties of woven/nonwoven composite geotextile (filament woven/short fiber nonwoven composite geotextile, split film woven/short fiber nonwoven composite geotextile, short fiber nonwoven/filament woven/short fiber nonwoven composite geotextile) testing items: unit area mass, unit area mass deviation rate, thickness, thickness deviation rate, amplitude deviation rate, tensile fracture strength (longitudinal and transverse), fracture elongation rate, bursting strength Trapezoidal method tearing strength (transverse, transverse), acid and alkali resistance (strength retention rate, breaking elongation retention rate), abrasion resistance (strength loss rate), melting point, asphalt absorption, impregnation, effective pore diameter, aging resistance tensile strength retention rate, ultraviolet resistance, seepage resistance (hydrostatic pressure resistance, permeability coefficient), constant load elongation, equivalent pore diameter, dynamic perforation (cone fall) performance, friction coefficient, oxidation resistance Creep performance, splicing strength, peeling strength, longitude and latitude density deviation, vertical permeability coefficient, artificial climate aging fracture strength retention rate, artificial climate aging fracture elongation retention rate, flat water flow rate and other appearance quality: appearance defects (uneven fabric surface, creases, debris, edge defects, damage, etc.), etc Function of testing report:1. Project bidding: Issue authoritative third-party CMA/CNAS qualification report 2. Online e-commerce platform entry: Quality inspection report recognized by major e-commerce platforms 3. Used as a sales report: issuing legally effective testing reports to make consumers more confident 4. Papers and research: Provide professional personalized testing needs 5. Judicial services: providing scientific, fair, and accurate testing data 6. Industrial problem diagnosis: Verify the troubleshooting and correction of industrial production problems100% inspection and testing process:1. Telephone communication and confirmation of requirements 2. Recommend solutions and confirm quotations 3. Mail samples and arrange testing 4. Progress tracking and result feedback 5. Provide reports and after-sales service 6. If urgent or priority processing is requiredTesting and testing characteristics:1. The testing industry is fully covered, meeting different testing needs 2. Fully cover the laboratory and allocate localized testing nearby3. Engineers provide one-on-one services to make testing more accurate 4. Free initial testing, with no testing fees charged 5. Self service order delivery for free on-site sampling 6. Short cycle, low cost, and attentive service 7. Possess authoritative qualifications such as CMA, CNAS, CAL, etc 8. The testing report is authoritative and effective, and is generally used in China
