Neoprene lastikuw ɲagaminen bɛ kɛ ni neoprene lastikuw ye, resin tackify, nɛgɛ ɔkisizɛni, furajiw, antioxydants, fillers, accelerators,
crosslinking agent ani a ɲɔgɔnnaw.
I. Kloroprene ka lastikuw .
Kuloroprene lastikuw, n’a bɛ fɔ fana ko polikuloroprene, o ye 2-kuloro-1,3 butadiyɛni ye i n’a fɔ fɛn fɔlɔ min bɛ kɛ ni polimɛri ye min bɛ kɛ ni emulsion ye ani a ye elastomer suguya dɔ sɔrɔ.
Elastomer. Kuloroprene lastikuw ye flakɛ finman walima jɛman ye walima u ka gɛlɛn, ni kristalɛ ye min bɛ se ka wuli, nɔrɔ ɲuman, fanga ka bon ani janya. Kɔrɔya ɲuman, funteni, tulu ani kemikaliya bɛ se ka kɛ. Weelekun ni ozɔni kɔrɔya kɛlɛli bɛ filanan kɛ ni etiliyɛn propilɛni lamini ni butili lastikuw ye. Funteni kunbɛncogo ani nitirili lastikuw. Asidi inorganique ni alkali corrosion (Asidi inorganique) ni alkali sɔgɔli bɛ se ka kɛ. A bɛ ni tasuma-fanga-ko ye. Funteni min ka jugu dɔɔni, kuran insulasi man ɲi.
2, resin tackify .
Tackifier resin ye fɛn nafama ye min bɛ sɔrɔ solvent-based neoprene adhesive la, min bɛ se ka jɛɲɔgɔnya fanga, nɛgɛmafɛnw, funteni kunbɛn, ji kunbɛncogo ani kɔrɔya kunbɛncogo ɲɛ.
Cɛnimusoko ni kɔrɔya kɛlɛli. Tackifier resin minnu bɛ kɛ, olu ye alikili fenɔliki resinw ye minnu bɛ se ka wuli, petoroli resinw, terpene fenɔli resinw, terpene resinw, rosiniw ka resinw, gumarone resinw, rosini ɛsitɛriw, poli a-methylstystyne ani o cogo la. Olu la, tert-butylphenol formaldehyde resin (2402 resin) de bɛ nɔ ɲuman bila. Tackifier resin bɛ se ka nɔ bila neoprene lastikuw ka kristalini na. Terpene fenɔli rezɛn ye resin ye min tɛ se ka a yɛrɛ minɛ, o bɛ se ka nɔrɔli waati janya, ani ka adhesive layer kɛ soft, gumarone resin ye fana ka neoprene adhesive kɛ .
Gumarone resinw fana bɛ dɔ fara neoprene nɛgɛw ka jɛɲɔgɔnya fanga kan. Kuloroprene rubber AF ye asidi karɔkisiliki CR ye, min ni nɔrɔli sirili fanga sigilen bɛ sigi senkan funteni teliya la, delaminasiyɔn kɛlɛli ka bon, nka, k’a sababu kɛ a bɛ se ka kɛ, nɛgɛtigɛbana bɛ wuli ka bɔ a maracogo la, o bɛ sɔrɔ oksizɛni magnɛsimu ka ɲɔgɔndan nɔ fɛ. O la, AF neoprene nɔrɔlen labɛnni na walasa ka sɔgɔsɔgɔninjɛ sabatili ɲuman sɔrɔ ani ka baara kɛcogo ɲuman sɔrɔ, o ka kan ka fara 2402 resin hakɛ kan, ani oksizɛni magnɛsimu ka kan ka kɛ ka kɔn ka rezɛn sɔrɔ walasa ka kelatew sɔrɔ, o bɛ se ka oksizɛni magnɛsimu ni hidrɔzili tilennen bali ani ka dɔ fara viscosité sabatili kan ani ka sigida sumaya.
3, nɛgɛ ɔkisizɛniw .
Nɛgɛ ɔkisizɛni minnu bɛ sɔrɔ nɛgɛw la minnu bɛ kɛ ni nɛgɛ ye, olu jɔyɔrɔ naani bɛ u la: asidi absorber, anti-scorch agent, vulcanizing agent, resin reactant. Waati tɛmɛnen kɔfɛ, neoprene lastikuw bɛna kuloridi idɔrɔji hakɛ nɔfɛta bɔ, o bɛ se ka polimɛriw tiɲɛni wɛrɛw sabati, wa u bɛna nɛgɛw ni fiɲɛ nafamaw tiɲɛ, ka nɛgɛ ɔkisizɛni fara a kan, o bɛ se ka kuloridi idɔrɔji minɛ walasa a kana tiɲɛ. Nɛgɛ ɔkisidi minnu bɛ kɛ caman na, olu ye ɔkisizɛni zinki ni magnɛsimu ye. Magnesium oxide ka baara ye ka asidi minɛ, ka kɔn ka a yɛrɛ minɛ, ka anti-scorch, vulcanization, etc. A ye neoprene adhesive yɔrɔ ye min nafa ka bon kosɛbɛ. Manje ɔkisizɛni ni resini sani a ka kɛ, o bɛ se ka funteni kunbɛncogo ɲɛ ani ka delamination sanji bali, magnɛsi ɔkisidi tata hakɛ min bɛ kɛ ka kɔn furakɛli ɲɛ ani a nɔrɔli nafa bɛ nɔ bila, ni oksizi hakɛ bɛ caya, nka funteni fanga ka bon, nka ji nɔrɔlen sabatili bɛ dɔgɔya. Oksizɛni magnɛsimu farali bɛ se ka filimu nɔrɔlen teliya kosɛbɛ ka ja, wa a bɛ se ka jɛɲɔgɔnya fɔlɔ fanga bonya kosɛbɛ, o bɛ se ka kɛ sababu ye ka a sababu kɛ manje yeelenma ye min bɛ kɛ ni ɔkisizɛni ye min bɛ kɛ ni manje ye walima ni oksizɛni magnɛsi ye min bɛ baara la. Okisizɛni yeelenma ye mugu finman ye min tɛ ali ye, a kasa tɛ bɔ ani a tɛ diya. Densité relative 3. 58, Melting Point 28520C, tobilikɛyɔrɔ 36000C fiɲɛ kɔnɔ bɛ se ka gazi ɲuman ni ji minɛ dɔɔni dɔɔni walasa ka magnesium carbonate basigilen sɔrɔ Zɛnki ɔkisizɛni faralen kuloropɛrɛni nɔrɔlen kan, o bɛ se ka jɔyɔrɔ ta asidi tali la, nka o ye fɛn ye min bɛ kɛ ka fɛnɲɛnamafagalanw ta, o tɛ ko ye min bɛ kɛ ni kuntilenna ye barisa kuloroprene nɔrɔli fanba ye kɛnɛma funteni ye ni nɛnɛ ye ka da a kan a furakɛli tɛna kɛ ni fɛnɲɛnamafagalanw ye, nka a bɛ kɛ sababu ye fana ka a kɛ sababu ye ka a kɛ sababu ye ka a kɛ ka a kɛ cogo min na. O waati kelen na, zinki ɔkisidi bɛ se ka ji nɔrɔlen kɛ fɛn ye min bɛ kɛ fɛn ye min bɛ kɛ fɛn ye min bɛ kɛ fɛn ye min bɛ kɛ fɛn ye min bɛ kɛ fɛn ye min bɛ kɛ fɛn ye min bɛ kɛ fɛn ye min bɛ kɛ fɛn ye min bɛ kɛ fɛn ye min bɛ kɛ fɛn ye min bɛ kɛ fɛn ye min bɛ kɛ fɛn ye min bɛ kɛ ka a kɛ fɛn ye min bɛ kɛ ka a kɛ fɛn ye min bɛ kɛ ka a kɛ fɛn ye min bɛ kɛ ka fɛn dɔ kɔrɔ, zinki bɛna kɛ ka a tigi ka kɔrɔya sabati. Ka da o kunw kan minnu fɔra sanfɛ, olu bɛ se ka zinki ɔkisizɛni tiɲɛ tiɲɛ na, jamana wɛrɛw ka kuran minɛnw ni CR nɛgɛ ye, o ma zinki ɔkisizɛni fara a kan, kola bɛ kɛ kɛnɛ kan, a tɛ kɛ layɛrɛ ye. Ni zinki ɔkisizɛni fana tɛ se ka sirili fanga wajibiyalen sɔrɔ, nka a bɛ se ka kɛ fana ka a yɛrɛ tanga nɛgɛmafɛnw ma minnu bɛ nɔrɔ a la, walasa ka nɛgɛ bali ka don a la waati jan kɔnɔ .
Aw bɛ jeli ni sanji bɔ, wa a tɛna kɛ sababu ye ka kola ka fasa fara ɲɔgɔn kan. Ni neoprene adhesive jɛɲɔgɔnya min bɛ kɛ funteni caman na, aw bɛ o hakɛ fitinin (1~3 kopi) fara a kan ultra-fine zinc oxide active nafa ka bon.
