• Alkali funtenimanw – bɛ bin gilasi kan

O de kama, ka finimugu dafalen mara, o nafa ka bon kosɛbɛ kemikɛli baara la. Ni aw bɛ baara kɛ ni HF ye, aw bɛ PTFE filimu saniyalen jateminɛ o nɔ na.

Funteni nɔ min bɛ sɔrɔ kemikaliw ka rezisti la

Funteni bɛ kɛ i n’a fɔ fɛn nafamaba min bɛ kemikɛli kɛlɛli ɲɛminɛ. A ka baarakɛcogo kuntaalajan funteni hakɛ kɔnɔ (a ka c’a la -70°C fo 260°C), PTFE ka kemikaliya sabatili tɛ nɔ bila a la kosɛbɛ.

Nka, ni funteni basigilen tɛmɛna 260°C kan, o bɛna kɛ:

• Aw bɛ PTFE ka kemikaliya baarakɛbaliya dɔgɔya dɔɔni dɔɔni
