ሁላችንም እንደምናውቀው, ማገድ ቀበቶ (የመገደብ ገመድ በመባልም ይታወቃል) is one of the most important standards to measure the performance and quality of የጅምላ ቦርሳዎች products. የእገዳው ቀበቶው የመጫን አቅም በቀጥታ የምርቶችን ጥራት እና ደህንነት ይነካል. ስለዚህ የጭካኔ ቦርሳዎች የእስር ቤት እና የእገዳ ገመድ የመጫን አቅም እንዴት መፈተሽ እንደሚቻል? Hebei Wanhefeng Packaging Co., ሊሚትድ. explains the following test methods for the load-bearing performance test of space bag sling and suspension rope test methods, hoping to be useful to you:
- Sampling method
At least two suspension band specimens of appropriate length are randomly intercepted at የጅምላ ቦርሳዎች suspension rings.
- Elongation test
The specimens are mounted on a tensile testing machine. After applying a 196N tightening load, a 100 mm distance marking line is drawn. When the load reaches 30% of the tensile strength f, the distance between the marking lines is measured.
Elongation (%)=[(l-100)/100]*100%
“L” means the distance between the lines, ሚ.ሜ, when the load reaches 30% of the tensile strength.
- Tensile Strength Test
The specimens were fixed on the fixture of a tension tester with a distance of 220 ሚ.ሜ. Tensile strength was measured at a speed of about 100 mm/min.
Above are three steps of የጅምላ ቦርሳዎች sling and sling test. Without sampling, the overall quality of the product cannot be reflected. The elongation test is very important for lifting operation, and the tensile strength affects the safety of operators when lifting.
