1. Breaking Ahoɔden: Adesoa Tumi Metric

1.1 Dɛn ne Ahoɔden a Wɔbubu?

Ahoɔden a ɛbubu (a wɔsan frɛ no break force anaa tensile strength) ne ahoɔden a ɛsen biara a ahama betumi agyina ano ansa na abubu. Sɛnea ASTM D3950 kyerɛ no, wɔde susuw ahoɔden a ɛma wobubu denam twe a wɔtwe abɔso nhwɛsode bi kosi sɛ ɛbɛdi nkogu, na wɔkyerɛw ahoɔden a ɛsen biara a wɔanya no.

Wɔtaa da ahoɔden a wɔde bubu abubu adi wɔ:

2. Elongation: Ntrɛwmu Suban Metric

2.1 Dɛn ne Elongation?

Elongation (a wɔsan frɛ no elongation at break) yɛ dodow a ahama bi trɛw ansa na abubu, a wɔda no adi sɛ ne mfitiase tenten no ɔha biara mu nkyem 100. Sɛnea ASTM D3950 kyerɛ no, wɔsusuw elongation wɔ tensile test koro no ara a ɛkyerɛ ahoɔden a ɛma wobubu no mu.

Wɔ PET abɔso ho no, elongation wɔ break mu taa fi 10% kosi 18% , ɛba fam kɛse sen PP strap (12–20%) na ɛba fam kɛse sen nylon (30%+).
