Nin barokun bɛna grafite pakew sɛgɛsɛgɛli kɛcogo ɲɛfɔ, ka fɛɛrɛ jɔnjɔnw ɲɛfɔ i n’a fɔ sɛgɛsɛgɛli, farikolo yɔrɔw sɛgɛsɛgɛli, kemikoro kɛcogo sɛgɛsɛgɛli, ani sigili baarakɛcogo sɛgɛsɛgɛli.
1. Sampling ani misali labɛnni .
Kɔrɔbɔli kɛcogo fɔlɔ ye misali tacogo ye walasa ka mɔgɔ jiralenw ka misaliw sɔrɔ. Fɔlɔ, ka da grafite pakew pakecogo kan (misali la, rolls, blocks, walima granules), misali tacogo bɛ latigɛ ka kɛɲɛ ni sariyaw ye minnu bɛ tali kɛ o la (misali la, GB/T 18341 walima ASTM D297). A ka c’a la, misaliw bɛ sugandi k’u kɛ k’a sɔrɔ u ma kɛ cogo la min tɛ kelen ye, ka bɔ kuluw walima yɔrɔw la minnu tɛ kelen ye walasa ka sigida cogoyaw bali ka nɔ bila jateminɛ bɛɛ lajɛlen na. Sɛgɛsɛgɛli kɛlen kɔfɛ, fɛnw ka kan ka mara yɔrɔ jalen na walasa ka ji minɛcogo ni a nɔgɔli bali.
O kɔfɛ, misali labɛnni, i n’a fɔ tigɛ, sɔgɔli, walima digili, o bɛ kɛ walasa ka sɛgɛsɛgɛli kɛrɛnkɛrɛnnen ka ɲininiw dafa. Misali la, farikolo yɔrɔw sɛgɛsɛgɛli bɛ se ka kɛ ni fɛnw ye minnu bɛ se ka kɛ fɛn kɛrɛnkɛrɛnnenw ye, ka sɔrɔ kemikaliya sɛgɛsɛgɛli bɛ kɛ ni mugu sɛgɛsɛgɛli kelen ye.

2. Farikolo yɔrɔw sɛgɛsɛgɛli .
Graphite fillers farikolo cogoyaw ye u ka baarakɛcogo jusigilan ye, kɛrɛnkɛrɛnnenya la, density (dansi), gɛlɛya, compression rebound (damatɛmɛni), ani thermal conductivity (sumalabɔli).
1.Density testing: Density bɛ jate ni sɛgɛsɛgɛli dɔ girinya ni a hakɛ sumani ye, a ka c’a la, a bɛ baara kɛ ni jiginni fɛɛrɛ ye walima jateminɛ sumanikɛcogo ye. Density bɛ nɔ bila pakew sigili nafa la k’a ɲɛsin u ma; Ni density (dansi) ka bon kojugu walima a ka dɔgɔn, o bɛ se ka kɛ sababu ye ka faratiw lase mɔgɔw ma.
2.Sɛgɛsɛgɛli gɛlɛn : Kɔgɔjida gɛlɛya sɛgɛsɛgɛlikɛla walima microhardness tester bɛ kɛ ka pakew ka degun fanga jateminɛ walasa a ka se ka sɛgɛnbaliya kunbɛn degunba la.
3.compression rebound: Simulasiyɔn baarakɛcogo lakikaw la, degun bɛ kɛ misali la ani a degun hakɛ ni a kɔsegincogo bɛ suman walasa k’a janya jateminɛ-term.
4.Thethermal conductivity testing: Graphite fillers ka funteni-taama-cogo bɛ suman ni laser flash fɛɛrɛ ye walima steady-state heat flow method. O nafa ka bon kɛrɛnkɛrɛnnenya la baarakɛminɛnw na minnu bɛ baara kɛ sanfɛ-Furakɛcogo cogoyaw la.
3. Kimiw ka ɲɔgɔn sɔrɔcogo sɛgɛsɛgɛli .
Graphite packing sabatili kemikaliya ye a ka sɔgɔli kunbɛncogo kunba ye, o la, kemikorow ka ɲɔgɔnfaamu sɛgɛsɛgɛli tigitigi de ka kan. Kɔrɔbɔlifɛn jɔnjɔnw ye karɔbɔli hakɛ ye, a bɛ kɛ ni bɔgɔ ye, a bɛ kɛ ni kisɛ ye, ani nɛgɛ nɔgɔlenw.
1.Carbon content determination: jenini-infrarouge absorption fɛɛrɛ walima titration fɛɛrɛ bɛ kɛ walasa grafite pake ka bɛn saniya sariya ma (a ka c’a la, kabon hakɛ min ka bon ni 90% ye, o de wajibiyalen don).
2.Ash Content Test: A sɛgɛsɛgɛli bɛ jeni funteni caman na walasa ka fɛnɲɛnama tolenw hakɛ jateminɛ. Ash hakɛ caya kojugu bɛ se ka nɔ bila pakew ka sɛgɛnbaliya la.
3.Sulfur kɔnɔkow sɛgɛsɛgɛli: A ka bon-Frequency infrared carboned carbon-sulfur analyzer walima chimique titration fɛɛrɛ bɛ kɛ ka kisɛkisɛ hakɛ kɔlɔsi walasa ka dɔ bɔ a sɔgɔli farati la minɛnw na.
4.Nɔgɔ nɔgɔ dɔnni: Spectroscopic Analysis (i n’a fɔ XRF walima ICP-OES) bɛ kɛ ka nɛgɛmafɛnw kɔnɔkow dɔn i n’a fɔ nɛgɛ ni nikɛri walasa u kana a dɔn ko u tɛ se ka kɛ ni kunnafonidilanw ye.
4. Sealing baarakɛcogo sɛgɛsɛgɛli .
Graphite packing ka baara laban ka kan ka sɛgɛsɛgɛ ni dasiri sɛgɛsɛgɛliw ye. Fɛɛrɛ minnu bɛ kɛ tuma caman na, olu ye degunw lafiyali sɛgɛsɛgɛliw ye ani bɔgɔbɔli hakɛ sɛgɛsɛgɛliw.
1.compression stress relaxation test: Nin sɛgɛsɛgɛli in bɛ pakew ka degunw cogoya ladege- waati kɔnɔ sigilan kɔnɔ ani ka degunw toli suman waati kɔnɔ walasa k’a janya jateminɛcogo jateminɛ.
2.Leakage Rate Test: Paki bɛ sigi sigilan kan min bɛ kɛ ka kɛɲɛ ni sariya ye, gazi walima ji bɛ don a kɔnɔ, ani degun bɛ kɛ walasa k’a lajɛ ni ji bɔli hakɛ bɛ bɛn izini sariyaw ma (i n’a fɔ API 622).
5. Kɔrɔbɔli rapɔɔri ani jogoɲini .
Kɔrɔbɔli fɛnw bɛɛ dafalen kɔfɛ, kunnafoniw ka kan ka lajɛ ani sɛgɛsɛgɛli rapɔɔri camanba dɔ min bɛ sɔrɔ, i n’a fɔ misali kunnafoniw, sɛgɛsɛgɛli fɛɛrɛw, jaabiw sɛgɛsɛgɛli, ani dantigɛliw. Fɛn minnu tɛ sariyaw dafa, kunw ka kan ka sɛgɛsɛgɛ ani ɲɛtaa ladilikanw ka kan ka di. Ka fara o kan, tɔnw bɛ se ka spot sɛgɛsɛgɛli basigilenw fara ɲɔgɔn kan ni sabanan-party testing ye walasa ka grafite pakew cogoya n’u sabatili sabati ka taa a fɛ.
