Mfiri Ahoɔden & Dimensional Stability

1. Ahoɔden a Wɔde Tensile

Density Level a Ɛwɔ Hɔ	Ahoɔden a Wɔde Tensile	Adwinnade a wɔde yɛ adwuma
Density a ɛkorɔn sen biara	Mpɛn pii no, ɛkorɔn sen saa	Nhama pii kyɛ adesoa wɔ unit trɛw biara mu
Ɛkɔ soro dodo	Ebia ɛbɛyɛ asasetaw anaasɛ ɛbɛkɔ fam	Intensified yarn crimp ma fiber a wɔde di dwuma no so tew; ntama a ɛyɛ den

Hyɛ no nsow a mfaso wɔ so: Wɔ nnwuma a ɛhwehwɛ ahoɔden a ɛsen biara a wɔde twetwe nneɛma (sɛ nhwɛso no, conveyor belts a ɛtrɛw wɔ nhyɛso kɛse ase) ho no, fa si w’ani so sɛ wobɛma density a ɛkɔ fam kosi nea ɛkorɔn. Nanso kwati sɛ wobɛma wo ho ayɛ den dodo, a ɛma wobrɛ ntɛm wɔ adesoa a ɛyɛ den ase.

2. Tear Ahoɔden – U-Curve a Wɔadan no

Tear ahoɔden ne ade a ɛyɛ nwonwa sen biara a density nya so nkɛntɛnso. Bere a wɔde PTFE akata so akyi no, polymer resin to nhama a wɔanwene no mu wɔ nea ɛwɔ hɔ no mu. Abusuabɔ no di U-shaped curve a wɔadan no akyi :

Density Level a Ɛwɔ Hɔ	Tear Ahoɔden	Adwinnade a wɔde yɛ adwuma
Density a ɛba fam	Hia	Nsonsonoe akɛse a ɛda nhama ntam no ma asaawa no bubu nnidiso nnidiso; nhama ntumi nkɔ akuwakuw

Key takeaway: Wonya ahoɔden a ɛsen biara a wɔde tew no wɔ density a ɛkɔ fam mu , ɛnyɛ density a ɛkorɔn sen biara. Eyi taa yɛ nea ɛne nsusuwii bɔ abira.
