PTFE fini min bɛ funteni caman na, o ka ozɔni kɔrɔya kunbɛnni

Jiangsu Aokai New Materials, n’o ye PTFE fini funteniman dilannikɛla ŋana ye ani a sɔrɔyɔrɔ izini ye, o bɛ daminɛkuma caman di aw ma. Fibre de verre fini min dilannen don ni politetrafluoroéthylène (PTFE) ye, o bɛ kɛ ni kemikaliya baarakɛbaliya ɲuman ye, wa a ka c’a la, a bɛ ozɔni kɔrɔya kunbɛncogo ɲuman di.

A ka molekiyɔmu jɔcogo kɛrɛnkɛrɛnnen kosɔn, PTFE bɛ ozɔni kɛlɛli barikama jira cogoya jɔnjɔnw na. Fluorin dafalen carbone-fluorine (CF) jɛɲɔgɔnya bɛ waso ni jɛɲɔgɔnya fanga ye min ka bon kosɛbɛ, o bɛ se 485 kJ/mol ɲɔgɔn ma. O waati kelen na, a ka molekiyɔmuw jɔcogo sɛrɛkili bɛ kɛ fluorine atomu lakanani lakananba ye, min bɛ oksidan barikamaw bali i n’a fɔ ozɔni ka bin kɔnɔna molekiyɔmu cakɛda kunba kan min bɛ wele ko carbone-carbone (CC).

O bɛɛ n’a ta, ozɔni bɛ se ka PTFE sanfɛla cogoya caman Changer ani ka fɛn caman wuli ka bɔ a la kemikoro ni farikolo ta fan fɛ. Kɔlɔsiliw y’a jira ko PTFE min bɛ ozɔni na, o ka sɔgɔsɔgɔ hakɛ bɛ caya siɲɛ saba ɲɔgɔn ka tɛmɛ fiɲɛ sigida la, o ni sɛgɛn taamasiɲɛ jɛlenw bɛ taa ɲɔgɔn fɛ. O bɛ sɔrɔ kosɛbɛ ozɔni fɛ dugukolo sanfɛla oksidan, molekiyɔmu jɛɲɔgɔnya kari ani fɛnw nɔgɔyali.

Ni ozɔni bɛ waati jan kɔnɔ, kɛrɛnkɛrɛnnenya la baarakɛyɔrɔ gɛlɛnw na i n’a fɔ funteni caman ani ozɔni hakɛ caman, PTFE fini min funteni ka bon, o bɛna bɔ dɔɔni dɔɔni ka bɔ tiɲɛni na min bɛ kɛ ni mikroskɔpi ye ka taa a bila baarakɛcogo dɛsɛ makɔrɔsikɔpi la, ni dɛsɛ jiracogo kɛrɛnkɛrɛnnenw ye nin cogo la:
