Analyse Du Moulding Processus Ka Da Ni Fenɛtiri Sealant

I n’a fɔ sow datugulanw yɔrɔ koloma dɔ, da ni finɛtiri sirilanw dilanni kɛcogo bɛ nɔ bila fɛn dilannen nɔrɔli la, a ka waati kunbɛncogo la, ani a datugucogo la. Dɔnniya siratigɛ la, fɛn dilanni kɛcogo tɛ dan sigilan ka jogo ɲuman dɔrɔn ma, nka a bɛ a sabatili sabati waati jan kɔnɔ fana sigida suguya caman na.

 

Da ni finɛtiri sirilanw dilanni taabolo bɛ kɛ ni fɛɛrɛ jɔnjɔn naani ye: fɛn fɔlɔw ɲagamini, fɛn basigilenw labɛnni, faralifɛnw jɛnsɛnni, ani fɛn dilanni laban. Fɔlɔ, basi polimɛri (i n’a fɔ silikoni, poliyuritan walima akirilati), fasafɛnw (i n’a fɔ karɔbɔni kalisiyɔmu, karɔbɔni nɛrɛma), ani faralifɛnw (i n’a fɔ plastiki ni crosslinkers) bɛ pese ka ɲɛ ka kɛɲɛ ni furakɛlicogo wajibiyalenw ye. O ɲagaminen kɛcogo ka kan ka kɛ teliyaba-filɛlan kɔnɔ walasa ka fɛnw tilatilali kɛ cogo kelen na ani ka sigida hakɛ danfara minnu bɛ nɔ bila baarakɛcogo la.

Basifɛnw labɛnni waati la, polimɛri bɛ kɛ ni kemikɛli ye walima ka fɛn dɔw sɛmɛntiya farikolo la walasa ka se ka viskoelasitiki ni kɛnɛyacogo ɲininenw sɔrɔ. Misali la, silikɔni sigilanw bɛ baara kɛ ni platini-catalyzed condensation reaction ye walasa ka polimɛriw sinsinni kɛ ka kɛ rezo jɔcogo ye, o la, u bɛ sigilan elastiki dɔ dilan. Fɛn minnu bɛ fara ɲɔgɔn kan, olu jɛnsɛnni nafa ka bon kosɛbɛ. Nanoscale fillers jɛnsɛnni cogo kelen na, o bɛ se ka kɛ sababu ye ka degun hakɛw sɔrɔ sigida la, o bɛ dɔ bɔ sealant ka muɲuli la.

Fɛn dilanni labanw ye extrusion, molding walima injection molding ye. A ka c’a la, boon da ni finɛtiri datugulanw bɛ dilan ni bɔli kɛcogo ye min bɛ to senna, o yɔrɔ la, fɛn min bɛ bɔ ni juru ye, o bɛ nɔrɔlan digi ka kɛ fɛn kelenw ye, o kɔfɛ, u bɛ nɛnɛ ka gɛlɛya walasa ka a cogoya sigi. Sigilan kɛrɛnkɛrɛnnen dɔw bɛ se ka kɛ ni degun-mugu ye walasa ka jogindaw sigicogo wajibiyalenw dafa minnu cogoya tɛ deli ka kɛ.

Sigilan min dilannen don, o fana bɛ vulcanization walima curing kɛ walasa k’a ka masinko labanw sɔrɔ. Misali la, so funteni vulkanize (RTV) silikoni sigilanw bɛ kɛnɛya ni ji ye min bɛ bɔ fiɲɛ na, ka sɔrɔ poliyuritan sigilan fila-fɛn bɛ kɛnɛya joona u ɲagaminen kɔfɛ.

Kuma surun na, da ni finɛtiriw sigicogo ye fɛn dilanni dɔnniya, kemikɛli ani fɛn dilanni fɛɛrɛw faralen ɲɔgɔn kan kosɛbɛ. Taabolo dantigɛliw ɲɛnabɔli nafa ka bon kosɛbɛ walasa ka sigicogo ɲuman sabati ani ka fanga sabatili jɔ.
