Silikoni jilama (LSR) bɛ ɲagami ni fomu ye (farikolo walima kemikɛli), ani funteni ni vulkanizasiyɔn sɛnɛcogo la mɔli kɔnɔ, fomu bɛ gazi bɔ, o bɛ kɛ sababu ye ka fomu mikorosɛrini kɛ cogo kelen na ani cogo ɲuman na.
1. Fɛn minnu bɛ kɛ ka fɛnɲɛnamafagalanw labɛn:
Aw bɛ baara kɛ ni fila{0}}Silikoni jilama ye (A&B yɔrɔw). A ka c’a la, basi lastikuw bɛ kɛ ka kɔn-A bɛ labɛn ka kɛɲɛ ni a feerela ye. A ka c’a la, a ka ca a la, katalisita bɛ sɔrɔ a la, ani yɔrɔ B bɛ sɔrɔ a la. Ka kɛɲɛ ni fɛn laban ka baarakɛcogo wajibiyalenw ye (i n’a fɔ density, gɛlɛya, ani kulɛri), a bɛ se ka kɛ ko a ka kan ka kulɛri pastes, thermal conductive fillers (i n’a fɔ alumina), walima tasuma-fanga-minɛnw ani farankan wɛrɛw kan basi-lastikuw la. A ka c’a la, o farankanw bɛ ɲagami ɲɔgɔn na ni yɔrɔ A walima yɔrɔ B ye ka kɔn o ɲɛ.
2. Foaming Agent Introduction (foaming agent introduction) .Nin ye ɲɔgɔndan ye min nafa ka bon kosɛbɛ. Ka kɛɲɛ ni fomu suguya ye, a tilalen don kosɛbɛ fɛɛrɛko sira fila ye:
Taabolo: A bɛ kɛ ni supercritique ye CO2 .: Co2 jilama bɛ sumaya ani ka degun sɔrɔ ka se supercritique (supercritique) cogoya ma minɛn kɛrɛnkɛrɛnnenw fɛ. Metering and Injection: ka tɛmɛ high-pressure metering pompe tigitigi fɛ, CO2 hakɛ dɔ bɛ pikiri kɛ supercritique la silicone rubber liquid silicone la. Static mixing: component A (SCCO2 bɛ sɔrɔ a la kaban) ani yɔrɔ B bɛ ɲagami kosɛbɛ ni aw bɛ tɛmɛ ni ɲagamilan ye. O waati kelen na, SCCO2 bɛ wuli cogo kelen na lastikuw la tansiyɔnba kɔrɔ, ka kɛ ni{4}}fase kelen-kelen ɲagaminen kelen ye. O kɛcogo bɛɛ bɛ mara degunba la walasa CO2 kana boli ka kɔn a waati ɲɛ.
b) Foaming foaming agent chimique:Aw bɛ baara kɛ ni fɛnɲɛnamafagalanw ye minnu bɛ se ka tiɲɛ ni funteni ye, i n’a fɔ azodikarbonamidi (ac foaming agent). Taabolo: Pre-Aw ka fomulen mugu ɲagami ɲɔgɔn na ni a yɔrɔ A walima a yɔrɔ B ye wulilan kɔnɔ. Walasa ka a jira ko fura in nafa ka bon-Fura, a ka c’a la, a bɛ kɛ ni vacuum deaeration ye ɲagamini kɔfɛ walasa ka fiɲɛ min donna a la, o bɔ a wulituma na.
3.Vulkanizasiyɔn ni fomu:
Fomu farikolo la: Lastikuw pikiri kɛlen kɔ nɔgɔbɔlan kɔnɔ, degun bɛ bɔ, ani Co2 min bɛ kɛ ka ɲɛ kosɛbɛ, o bɛ wuli joona, o bɛ kɛ ka bugun nukiliw kɛ. O waati kelen na, funteni caman bɛ kɛ sababu ye ka vulkanization ni cross-likes reactions kɛ silicone rubber kɔnɔ, ka bulon jɔcogo ni formation seliw datugu.
Kimikisɛ fomu: Nɔgɔ hakɛ caman bɛ kɛ sababu ye ka kemikɛli fomulen kɛ, ka gaziw bɔ (i n’a fɔ N3, CO2). O waati kelen na, silikoni lastikuw bɛ kɛ vulkan ye, ani gaziw bɛ don lastikuw labɛnni na, ka seliw da.
4. Ka dugukolo ci:Vulkanization foaming cycle (Vulkanizasiyɔn) dafalen kɔfɛ (a ka ca a la segin tan kɔnɔ ka se miniti damadɔ ma), aw bɛ mɔni da wuli ka sɔrɔ ka fura in bɔ. K’a sababu kɛ LSR ka sɔgɔli dɔgɔyali ye, a ka c’a la, furaw tɛ nɔrɔ nɔgɔ la wa u bɔli ka nɔgɔn kosɛbɛ.
5. Post-Kuran (Vulkanizasiyɔn filanan) .(post-fura) Fɛn minnu bɛ kɛ fomu ye, a ka c’a la, olu mago bɛ post-furakɛli la foro kɔnɔ funteni na min bɛ se degere 150 ma - 200 degere 1-2 kɔnɔ.
