Rezini bɔgɔ furakɛcogo
Rezinɛ bɔgɔ furakɛcogo (min ka ca a la, a be kuma bɔgɔ filili kan ni nɔrɔnanw ye i n’a fɔ furan bɔgɔ wala alkaline phenolic resin) ye fɛɛrɛ jɔnjɔnw dɔ ye bi tile bɔgɔ bɔyɔrɔw la. A ka laɲinita jɔnjɔn ye ka bɔgɔ kɔrɔw labɛn kokura, k’u lakuraya ani ka baara kɛ n’u ye tugun cogo ɲuman na walisa ka dɔ bɔ musakaw la, ka bɔgɔ bɔcogo ɲuman lajɛ ani ka lamini nɔgɔ dɔgɔya.
A tɛ i n’a fɔ silika zɛli bɔgɔ, bɔgɔ min be nɔrɔ ɲɔgɔn na ni fɛnɲɛnamafagalanw ye, o bena sɔgɔ ani ka nɔgɔ bɔn kɔ, nka a tɛ tunu pewu. O kama, furakɛli kɛcogo jɔnjɔn ye ka bɔgɔ kɔrɔw ka fɛnɲɛnamafagalanw ni nɔgɔw bɔ u kan.
Nin ye furakɛcogo dafanin ani minan jɔnjɔnw ye minw be kɛ ka bɔgɔ nɔgɔ (an ka furan nɔgɔ self-hardening sand min be ta ka caya, o ta k’o kɛ misaliya ye):
1. Core baarakɛcogo: A dafanin "sand cycle"
Bɔgɔ furakɛli sira dɔ ye -datugunin ye, i n'a fɔ nin cogo la:
Bɔgɔ kɔrɔ → Bɔgɔ kɔrɔ → Bɔgɔ → Bɔgɔ bɔli → Sɛgɛsɛgɛli → Lakuraya fɔlɔ → Lakuraya filanan → Bɔgɔ funteni labɛnni → Ɲagamini → Bɔgɔ fili → Bɔgɔ bɔli → Bɔgɔ kɔrɔ
2. A be baara kɛcogo kelen kelen bɛɛ ani baarakɛminan jɔnjɔnw ɲɛfɔ ka gwɛ .
