Siç e dimë të gjithë, rrip pezullimi (i njohur edhe si litar i pezullimit) is one of the most important standards to measure the performance and quality of çanta me shumicë products. Kapaciteti mbajtës i rripit të pezullimit ndikon drejtpërdrejt në cilësinë dhe sigurinë e produkteve. Pra, si të testoni kapacitetin mbajtës të rripit të pezullimit të çantave me shumicë dhe litarit të pezullimit? Hebei Wanhefeng Packaging Co., Ltd. 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 çanta me shumicë 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, mm, 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 mm. Tensile strength was measured at a speed of about 100 mm/min.
Above are three steps of çanta me shumicë 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.
