compression permanent deformation rate ye kilisi kɔrɔlenba ye min bɛ se ka taamasiyɛn ɲɛnamaya dɔn, walima hali "veto" jiralan.
An bɛ se ka baara kɛ ni misali ɲɛnama ye walasa ka faamuyali sɔrɔ: sigilan bɛ i n’a fɔ spring kantigi.A ka baara koloma ye ka to ka fanga seginlen (contact stress) kɛ kɛnɛma yɔrɔ la ni a digilen don (a bɛ sigi groove kɔnɔ). O fanga seginlen in bɛ digidigi kosɛbɛ dasirilan yɔrɔ la, o bɛ kɛ sababu ye ka fɛnɲɛnamafagalan (tulu, ji, gazi, a ɲɔgɔnnaw) bali.
Dɛsɛ sababu tilennen : Ni "Sɔn" sɛgɛnna ani ka kɔrɔbaya, a tɛ se ka segin kɔ tugun, wa degun min bɛ kɛ, o bɛ jigin yɔrɔ kɔrɔlen jukɔrɔ, taamasiyɛn bɛ dɛsɛ.
Compression permanent deformation rate ye taamasiyɛn ye min bɛ "spring" rebound seko bɔnɛnen jateminɛ k'a ɲɛsin a ma.
Mun na o ye "master key" ye?
1. Sariyabaju jɔnjɔn min bɛ tali kɛ sigida la .
Sigili kunba ye ko ɲɔgɔndan degun bɛ tɛmɛ degun kan min bɛ sɔrɔ medium fɛ. Ni degun hakɛ banbali hakɛ ka bon kojugu, sigilan tɛ se k’a cogoya fɔlɔ sɔrɔ a flakɛlen kɔfɛ, wa o kɔlɔlɔ bɛ sɔrɔ ɲɔgɔndan degun na, o bɛna jigin kosɛbɛ.

2. A ye "farikolo sɛgɛsɛgɛli jaabi dafalen" ye min bɛ kɛ ka fɛnw kɔrɔbaya .
Deformation permanent rate compression tɛ baarakɛcogo kelen ye, nka a bɛ kɛ ka fɛnw tiɲɛni banbali jira fɛnw na minnu bɛ kɛ ka kɛɲɛ ni funteni, ɔkisizɛni, cɛmancɛ, waati ani fɛn wɛrɛw ye. Kun min na a bɛ kɛ sababu ye ka fɛn caman tiɲɛ, o fana ye kɔrɔya sigili sababuba ye:
Polimɛri cakɛda kari ni ɲɔgɔn cɛ: funteni ni ɔkisizɛni caman ka baara kɔrɔ, lastikuw ka cakɛda molekilɛri bɛna kari (o bɛ na ni nɔgɔya ni nɔrɔli ye) walima crosslinking tɛmɛnen (o bɛ sɔrɔ gɛlɛya ni tiɲɛni na), o fila bɛɛ bɛna a ka rezo elastiki tiɲɛ ani ka a seko tiɲɛ ka segin kɔ.
Plastikiw/suwɛriw labɔli walima u bɔli: Ni sigilanw bɛ tulu walima kemikɛlifɛnw na waati jan kɔnɔ, plastiki misɛnninw bɛ se ka bɔ walima ka u wuli. O bɛ tali kɛ mugu bɔnɛni na, o bɛ gɛlɛya, ka dɔgɔya, ani ka sɛgɛn.
Yɛlɛma minnu tɛ se ka segin kɔ: Lastikuw dɔw bɛna kɛ ni kemikaliya ye min tɛ se ka segin kɔ cogo dɔw la (i n’a fɔ silikoni ka lastikuw "segin" funteniba la), minnu bɛ u ka sɔgɔli tiɲɛ kudayi.
O la, degun banbali sɛgɛsɛgɛli hakɛ sumani ye tiɲɛ na siginiden kɔrɔya taabolo ye baarakɛcogo yɛrɛ la, wa a bɛ a ka baarakɛcogo koloma (Elasticity) bɔnɛ hakɛ fɔ.
