Jateminɛ kɛcogo jumɛnw bɛ PTFE-dalen fibreglasi fini na min bɛ se ka nɔrɔ ani ka saniya nɔgɔya la ka ɲɛsin tulu nɔgɔw ni buguri ma?

1. Kɔrɔɲɔgɔnmaya ni dugukolo fanga sɛgɛsɛgɛli (Wettability Basics) .

 

- Static Contact Angle : A bɛ suman ni ji ni diyodomethane (walima hexadecane) ye u danma. A ka c’a la, ji bɛ ɲɔgɔn sɔrɔ yɔrɔ min na, o bɛ tɛmɛ 110° kan. Tumu ni ɲɔgɔn cɛ yɔrɔ min ka bon, o b’a jira ko a bɛ se ka tulu nɔgɔli ni a nɔrɔli kɛlɛ.

- Rolling/Sliding Angle : Kɛrɛ min na, hakɛ kɛrɛnkɛrɛnnen dɔ jikuru dɔ bɛ daminɛ ka sɛgɛn ka bɔ yɔrɔ la min bɛ kɔrɔta dɔɔni dɔɔni. Ni a wulicogo ka dɔgɔn, o b’a jira ko a bɛ se ka sɔgɔsɔgɔ ka ɲɛ ani ka saniya nɔgɔya, o min nafa ka bon kɛrɛnkɛrɛnnenya la tulu nɔgɔ sɛgɛsɛgɛli la.

- Surface Free Energy Calculation:Polari ni dispersive yɔrɔw jate bɛ kɛ ni fɛɛrɛw ye i n’a fɔ Owens-Wendt. Ni dugukolo sanfɛla fanga dɔgɔyara (PTFE nafa ɲuman bɛ se 18–20 mN/m ma), a bɛ gɛlɛya ka taa a fɛ nɔgɔ gɛlɛnw ni jilamaw ka jigin ani ka jɛnsɛn.

 

2. Masina ka jateminɛ kɛ ni fɛnw ye minnu bɛ se ka sɔgɔsɔgɔ (Peel Force/Adhesion Force) .

 

- Standard Pressure-Sensitive Tape Peel Test : Kase standard kɛrɛnkɛrɛnnen dɔ (misali la, 3M 810 walima kaseti dantigɛlen min bɛ tansiyɔn sɛgɛsɛgɛli kɛ) bɛ digi PTFE kaseti sanfɛ ni rollo standard ye. Ni aw bilala ka jɔ waati latigɛlen kɔnɔ, aw bɛ 180° sɔgɔli sɛgɛsɛgɛli kɛ ni sɔgɔsɔgɔninjɛ sɛgɛsɛgɛli masin ye (aw ye sɛbɛn ɲɛ GB/T 2792 lajɛ). Ni sɔgɔsɔgɔninjɛ fanga dɔgɔyara, a bɛ barika sɔrɔ ka nɔrɔli kɛlɛ, ni a nafa ɲuman bɛ 0,1 N/25 mm duguma.

- Kɛrɛnkɛrɛnnenya la, nɔrɔli sɛgɛsɛgɛli cɛmancɛ la : Nɔrɔlifɛn minnu bɛ sɔrɔ tiɲɛ na baara la, i n’a fɔ nɛgɛso, yɛrɛnɔrɔlanw, walima nɔrɔlanw minnu bɛ wuli ni funteni ye, olu bɛ kɛ ka fanga suman min ka kan ka kɛ walasa k’u bɔ u sanfɛla la.

 

3. Sɛgɛsɛgɛli simulatigɛlenw walasa ka tulu kunbɛn ani ka saniya nɔgɔya

 

- Tulu nɔgɔw Sliding/Residue Fɛɛrɛ : Motɛri tulu hakɛ latigɛlen, tobilikɛtulu, walima tulu dilannen bɛ kɛ fɛn dɔ kan min kɔrɔtalen don yɔrɔ dɔ la. Tumu nɔgɔ janya jiginni janya walima yɔrɔ tolen kɛmɛsarada la a sanfɛla la, o bɛ suman.

- Saniyacogo ɲuman min bɛ kɛ ni wiping quantitative ye :

    - Dugukolo dilannen min bɛ kɛ ka kɛɲɛ ni sariya ye (karɔbɔni, tulu, ani asidi olɛki ɲagaminen) bɛ kɛ a la cogo kelen na ka ja. Fini min tɛ sɔgɔsɔgɔ, n’a ɲiginnen don ni ji ye ani safinɛ min tɛ fɛn kɛ, o bɛ kɛ ka a ko ka taa ɲɛfɛ ka segin ka segin ka kɛ siɲɛ hakɛ latigɛlen dɔ kɔnɔ doni sigilen dɔ kɔrɔ.

    - Jiangsu, fibreglasi fini minnu datugulen don ni PTFE ye, olu dilannikɛlaw bɛ baara kɛ ni kulɛri danfaralan ye walasa ka kulɛri danfara ΔE suman ka kɔn u ko ɲɛ ani u ko kɔfɛ, walima ka saniya nafa hakɛ jateminɛ ni dugukolo hakɛ tolen ye (gravimetric method). ΔE ka dɔgɔn ani a girinya tolen dɔgɔyali bɛ saniya nɔgɔya baarakɛcogo ɲuman jira. Kɔnɔnafili yɔrɔ min bɛ yɔrɔ saniyalen kan, o seginni hakɛ fana bɛ se ka suman.

- Quick Qualitative Test ni tulu taamasiɲɛ ye : Tumu taamasiyɛn bɛ kɛ ka tigɛli kɛ a sanfɛ. Aw bɛ a kɔlɔsi ni tintin bɛ dɔgɔya ka kɛ jikuruw ye minnu tɛ taa ɲɛ walima ni a bɛ jɛnsɛn tuma bɛɛ, o kɔ aw bɛ a ko ni fini jalen ye walasa ka a dɔn ni a bɛ bɔ nɔgɔya la. Ni a dɔgɔyara kosɛbɛ ani ni a bɔli nɔgɔyara, o b’a jira ko a bɛ se ka nɔgɔ kɛlɛ ani ka saniya nɔgɔya.

 

4. Bugun kɛlɛli ni fɛnɲɛnamafagalanw nɔrɔli sɛgɛsɛgɛli

 

- Bugun sigicogo : Kɔrɔbɔli buguri basigilen (misali la, ISO 12103-1 A2 buguri finman) bɛ to ka sigi a yɛrɛ la misali yɔrɔw kan minnu bɛ jɔ walima minnu bɛ 45° la, so datugulen kɔnɔ. Ni aw ye a gosi nɔgɔya la walima ka a fiyɛ ni gazi tansiyɔn dɔgɔman ye, buguri yɔrɔ/masa tolen bɛ suman ni ja sɛgɛsɛgɛli walima girinya jateminɛ fɛɛrɛw ye.

- Bugun bɔli fiɲɛbɔ fɛɛrɛ fɛ : Buguri hakɛ dɔnta bɛ seri ka kɛ kelen ye fɛn dɔ kan min bɛ jɛgɛn. Azote jibɔyɔrɔ dɔ jibɔ hakɛ bɛ bonya dɔɔnin dɔɔnin, wa fiɲɛbɔ teliya hakɛ fitinin min ka kan ka kɛ walasa ka buguri fiyɛ pewu, o bɛ sɛbɛn. Ni teliya bɛ dɔgɔya, buguri kɛlɛli nɔrɔli nafa ka fisa.

- Kuran sɔgɔli nɔw jateminɛni : Ikomi buguri sɔgɔli bɛ juguya tuma caman na ni kuran jɔlen ye, o la, a sanfɛla rezisti ni kuran sɔgɔli waati fana ka kan ka sɛgɛsɛgɛ walasa ka danfara don ni o nɔ bɛ bɔ kemikaliya kɛlɛli la walima kuran sɔgɔli la.

 

5. Ka dɛmɛ don Muɲuli jateminɛ na

 

- Kɔrɔya kɔfɛ funteni caman na (misali la, 260°C walima 300°C la) walima sɔgɔsɔgɔninjɛ/sɔgɔli kɔfɛ (Taber abrasion), ɲɔgɔnkanu yɔrɔ min fɔra sanfɛ, a ɲɛci fanga, ani saniyacogo ɲuman sɛgɛsɛgɛliw bɛ segin u kan walasa ka a jira ko baarakɛcogo kana tiɲɛ kosɛbɛ baara kuntaalajan waati.
