Design Principes Et Application Analyse De Structural Sealant

I n’a fɔ fɛnba min bɛ fara ɲɔgɔn kan bi jɔli ni izini na, jɔli sigilanw dilanni sariyakolow bɛ dɔnniya caman fara ɲɔgɔn kan ka bɔ fɛnw dɔnniya, mekaniki ani ɛntɛrinɛti baarakɛcogo la. U ka baara koloma ye ka jɛɲɔgɔnya sabatilenw sɔrɔ jɔli yɔrɔw ni ɲɔgɔn cɛ sirili ni u datugucogo fila bɛɛ fɛ, ka sɔrɔ ka sigida sɔgɔli ni masinw degun fana kɛlɛ.

 

Ni an y’a lajɛ fɛnw dilanni siratigɛ la, a ka c’a la, jɔli sigilanw bɛ sinsin polimɛri sigidaw kan, i n’a fɔ silikoni caman sɛmɛntiyalenw, poliyuritanw, walima polisulfide lastikuw. O basigifɛnw ka kan ka balansi ɲuman jira u ka wulicogo ni u fanga la-kɔrɔlen kɔfɛ, u bɛ kɛ nɔrɔlan ye min bɛ se ka ladamu joli lamagacogo la (i n’a fɔ funteni bonya ni u sɔgɔli) ka sɔrɔ ka doni jɔlenw ni doni fangamaw fana muɲu. Misali la, silikɔni sigilanw bɛ waati kunbɛnni sɔrɔ Si-O jɛɲɔgɔnyaw ka jɛɲɔgɔnya fanga caman fɛ, k’a sɔrɔ poliyuritanw bɛ u jigi da crosslink density kan walasa k’u gɛlɛya n’u gɛlɛya ladilan.

O dilancogo bɛ jatebɔ gɛlɛn de wajibiya nɔrɔlan ka masinko paramɛtiriw kan, i n’a fɔ sirili fanga, modulu ani jiginni seko. Ɛntɛrinɛti ɲɛmɔgɔw ka kan ka nɔrɔli kɛcogo latigɛ ka da joli bonya kan, substrat suguya, ani sigida cogoyaw (i n’a fɔ UV bɔli ani funteni jiginni).
