1. So funteni, Lamini jalen
Fɛnɲɛnɛmafagalan minnu bɛ kɛ fɛn bɛɛ ye-, olu fanba (i n’a fɔ akirilati ni epokisi) bɛ baara kɛ ka ɲɛ sigidaw la, so funteni (20-25℃) ani nɛnɛ bɛ kɛ yɔrɔ minnu na. O sigidaw ka ca birow kɔnɔ, sow kɔnɔ, ani izini nɔgɔmanw lajɛyɔrɔw la, wa u bɛnnen don fɛnw sirili ma i n’a fɔ papiye, plastiki ani jiri. Nin nɔrɔ ninnu bɛ kɛnɛya joona, wa u kɛli ka nɔgɔn, nka ni u bilala nɛnɛ na ka mɛn, o bɛ se ka kɛ sababu ye ka u sirili fanga tiɲɛ.
2. Lamini min ka funteni ka bon
A ka c’a la, nɔrɔ minnu bɛ se ka funteni caman sɔrɔ-, olu de wajibiyalen don forow la i n’a fɔ izini minɛnw lajɛli ani mobili dilanni. Misali la, silikɔni nɛgɛw bɛ to ka sabati funteni na min bɛ daminɛ degere -50 na ka se degere 300 ma, o b’a to u bɛnnen don ka motɛri yɔrɔw datugu walima ka pibilikiw datugu minnu funteni ka bon. Faan wɛrɛ fɛ, fenɔli resin nɔrɔlanw bɛ se ka funteni caman muɲu (fo ka se degere 500 ma ) wa u ka teli ka kɛ ka nɛgɛ yɔrɔw siri ni funteni caman ye. O sigidaw bɛ nɔrɔfɛnw de wajibiya minnu sabatili ka ɲi kosɛbɛ funteni ni oksidan na.
3. Lamini minnu bɛ ji la walima minnu bɛ ji jukɔrɔ
Baara minnu bɛ kɛ i n’a fɔ sow jɔli rido kogow sigili ani kurun dilancogo, olu bɛ nɔrɔfɛnw de wajibiya minnu bɛ ji kɛlɛ ani minnu tɛ se ka don a kɔnɔ. Poliyuritani nɛgɛmafɛnw, k’a sababu kɛ u ka polar kulu barikamaw ye, u bɛ jɛɲɔgɔnya barikamaw kɛ fɛn ɲiginnenw kan, wa hali u bɛ se ka kɛ ji jukɔrɔla jɔli la. Epoyi-nɛgɛw caman sɛmɛntiyalenw, ni u bɛ fasa jibɔlanw fara u kan, u bɛ dɔ fara u ka kɔgɔ fiyɛli sɔgɔli kunbɛnni kan, o de kama u bɛnnen don kɔgɔjida la.
4. Lamini minnu bɛ kɛ ni kemikɛli ye
Laboratowariw walima kemikɛli iziniw kɔnɔ, nɛgɛw ka kan ka se ka sɔgɔsɔgɔ ka bɔ kemikɛlifɛnw na i n’a fɔ asidiw, alkaliw ani furajiw. Fluorroubber walima polyimide nɔrɔlanw, k’a sababu kɛ u ka kemikaliya baarakɛbaliya ye, u bɛ se ka muɲu ni fɛnw ye minnu bɛ sɔgɔsɔgɔ kosɛbɛ, wa u bɛ kɛ ka caya pibilikiw datuguli la walima u tangalanw na.
Kuma surun na, jagokɛla ka nɔrɔlanw bɛnnen don sigida suguya caman ma, wa u suguya bɛnnen ka kan ka sugandi ka da baarakɛcogo kɛrɛnkɛrɛnnenw kan. Fɛnw jateminɛni ka ɲɛ i n’a fɔ funteni, nɛnɛ ani fɛnɲɛnamafagalanw tali, o nafa ka bon kosɛbɛ walasa ka baara kɛ ni nɛgɛdaga in baarakɛcogo ye ka ɲɛ ani ka a to a kɛli ka kɛ cogo la min tɛ mɔgɔ tɔɔrɔ ani min bɛ mɛn.
