Ozone Aging Resistance na PTFE High-Temperature Cloth

Jiangsu Aokai New Materials, ƙwararrun masana'anta da masana'anta na PTFE babban zane mai zafi, yana ba ku cikakken gabatarwa. Polytetrafluoroethylene (PTFE) mai rufi fiberglass zane yana da kyakkyawan rashin aiki na sinadarai kuma gabaɗaya yana ba da ƙwararren juriyar tsufa na lemar sararin samaniya. Duk da haka, ba shi da cikakken kariya daga zaizawar ozone, kuma gabaɗayan aikinsa yana tasiri sosai ta hanyar tattarawar ozone, yanayin yanayi, ci gaba da bayyanar lokaci da sauran abubuwan waje.

Godiya ga tsarinsa na musamman na kwayoyin halitta, PTFE yana nuna juriya mai ƙarfi a ƙarƙashin daidaitattun yanayi. Cikakkiyar ƙorafin carbon-fluorine (CF) haɗin gwiwa yana alfahari da babban ƙarfin haɗin gwiwa na kusan 485 kJ/mol. A halin yanzu, tsarinsa mai karkata kwayoyin halitta yana samar da garkuwar kariya mai yawa na atom na fluorine, yana hana oxidants masu karfi irin su ozone daga kai hari kan babban sarkar kwayoyin carbon-carbon (CC).

Duk da haka, ozone na iya canza yanayin yanayin PTFE da haifar da jerin canje-canjen sinadarai da jiki. Nazarin ya nuna cewa PTFE da aka fallasa ga ozone yana da juzu'in juzu'i kusan sau uku fiye da wanda ke cikin yanayin iska na yau da kullun, tare da alamun lalacewa. Wannan yana faruwa ne ta hanyar iskar iskar oxygen da ta haifar da iskar oxygen, karyewar hadi da laushin kayan abu.

Tare da ɗaukar dogon lokaci zuwa sararin samaniya, musamman a ƙarƙashin yanayin aiki mai ƙarfi kamar yanayin zafi mai girma da haɓakar sararin samaniya, zane mai zafin jiki na PTFE a hankali zai haɓaka daga lalacewar microscopic zuwa gazawar aikin macroscopic, tare da takamaiman bayyanar gazawar kamar haka:

Karye sarkar kwayoyin halitta da lalacewa Ozone yana karya sarƙoƙi na CC na PTFE kuma yana samar da ƙananan gutsuttsuran kwayoyin halitta kamar carbon tetrafluoride (CF₄) da carbonyl fluoride (COF₂). Wannan yana haifar da raguwar nauyin kwayoyin halitta da lalata aikin kayan aiki na asali.

Tsagewar saman saman da ƙumburi Shi ne abin da ya fi dacewa da tsufa. Kayan yana rasa sassaucin sararin samaniya kuma yana haifar da fashe-fashe mai haske kamar cibiyar sadarwa a ƙarƙashin damuwa, wato fashewar ozone. Tufafin ya zama mai tauri kuma ya karye, kuma tsufa mai tsanani zai ƙara haifar da ɓarna da lalacewar tsarin.

Ragewa a cikin kayan aikin injiniya Rarraba kayan aiki yana ci gaba da rage ƙarfin ƙwanƙwasa, haɓakawa a lokacin hutu, elasticity da sauran mahimman alamun inji. Juyawar saman da ke gaba, kwasfa da rage kauri zai kara raunana juriya da kwanciyar hankali.

Lalacewar tsarin sinadari na sinadari yana canza mahimmin sigogi kamar makamashin saman da kusurwar wetting. Fasa-fatsin da ba a iya gani ba da pores da aka samu ta hanyar zaizawar ozone za su faɗaɗa girmansu, suna raunanan ainihin hatimi da aikin keɓewa.

Juriya na lemar sararin samaniya na PTFE babban zafin jiki ba abu ne kawai ya ƙaddara ta tushen kayan kanta ba. Yanayin zafin jiki, hadewar tasirin tsufa da sauran yanayin waje suma suna taka muhimmiyar rawa a rayuwar sabis ɗin sa.

Babban zafin jiki yana haɓaka lalacewar ozone sosai. Ƙarƙashin yanayin zafin jiki mai ƙarfi, iskar oxygen mai ƙarfi na ozone yana ƙara lalata sarkar kwayoyin halitta na PTFE. Saboda haka, da dogon lokacin da sabis zafin jiki iyaka kayayyakin PTFE saukad da sharply daga 260 ℃ a cikin al'ada iska zuwa 200 ℃-220 ℃ a cikin ozone da kuma karfi oxidizing gas muhallin.

Akwai tasirin tsufa na haɗin gwiwa  tsakanin ozone da hasken ultraviolet. A cikin al'amuran waje, haɗin UV radiation da ozone yana haifar da ingantaccen sakamako mai lalacewa fiye da na abu ɗaya.
