Teflon an fi saninsa da polytetrafluoroethylene (taƙaice teflon na Turanci ko [PTFE, F4]), wanda aka sani da/wanda aka fi sani da "sarkin filastik", kuma aka sani da "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon". "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon". Yana da wani fili na polymer wanda aka yi da tetrafluoroethylene ta hanyar polymerization, kuma tsarinsa yana da sauƙi kamar - [-cf2-cf2 -] n-.

Polytetrafluoroethylene, wanda aka fi sani da sutura maras sanda ko sauƙin tsaftacewa. Wannan abu yana da halaye na acid da alkali juriya, juriya ga daban-daban kwayoyin kaushi, kuma kusan insoluble a duk kaushi. A lokaci guda, polytetrafluoroethylene yana da halaye na tsayin daka na zafin jiki, ƙimar sa na gogayya yana da ƙasa sosai, don haka ana iya amfani da shi don lubrication, amma kuma ya zama shafi mai kyau don sauƙaƙe tsaftace ciki na bututun ruwa.

Teflon plating yafi dogara ne akan wane irin tsari kuke son sanin yadda ake fesa. Abu mafi mahimmanci shi ne cewa murfin Teflon yana buƙatar gasa a yanayin zafi mai zafi kafin a iya amfani dashi.

Halayen Teflon:

Mara mannewa: Kusan dukkan abubuwa ba sa haɗuwa da murfin teflon.

Low zafin jiki juriya: mai kyau inji taurin; Ko da zazzabi ya faɗi zuwa -196 ° C, 5% elongation za a iya kiyaye. Har yanzu yana da taushi a -100 digiri.

High zafin jiki juriya: polytetrafluoroethylene shafi yana da kyau kwarai zafi da low zazzabi juriya. Yana iya jure babban zafin jiki zuwa 300 ° C na ɗan gajeren lokaci, gabaɗaya za'a iya amfani dashi akai-akai tsakanin 240 ° C da 260 ° C, kuma yana da kwanciyar hankali na thermal, yana iya aiki a yanayin daskarewa ba tare da haɓaka ba, kuma baya narke a yanayin zafi mai yawa. .

High lubrication: Shi ne mafi ƙasƙanci juzu'i coefficient a cikin m kayan. Yana da mafi ƙarancin ƙima na gogayya (0.04) tsakanin robobi. Mai laushi fiye da kankara.

Juriya na danshi: fuskar PTFE ba ta da ruwa da man fetur, kuma ba shi da sauƙi don tsayawa ga bayani yayin aikin samarwa. Idan akwai datti kadan, ana iya cire shi ta hanyar shafa kawai. Wani ɗan gajeren lokaci yana adana lokaci kuma yana inganta aikin aiki.

Wear juriya: Yana da kyakkyawan juriya na lalacewa a ƙarƙashin babban kaya. Ƙarƙashin wani kaya, yana da fa'idodi biyu na juriya da rashin mannewa.

Lalata juriya: polytetrafluoroethylene ne kusan free daga miyagun ƙwayoyi harin, kuma zai iya jure duk karfi acid (ciki har da aqua aqua), da karfi oxidants, rage jamiái da daban-daban Organic kaushi ban da narkakkar alkali karafa, fluorinated kafofin watsa labarai da sodium hydroxide sama da 300 ° C, da kuma zai iya kare sassa daga kowane irin lalatar sinadarai.

Juriya na tsufa: juriya na radiation da ƙarancin haɓakawa: ɗaukar lokaci mai tsawo zuwa yanayi, farfajiya da aikin ba su canzawa.

Incombustible: Oxygen iyaka index yana ƙasa da 90.

Acid da alkali juriya: wanda ba a iya narkewa a cikin acid mai ƙarfi, tushe mai ƙarfi da abubuwan kaushi na halitta (ciki har da acid sihiri, wato, fluoroantimonic acid).

Juriya na Oxidation: mai jurewa ga lalata ta masu ƙarfi masu ƙarfi.

Insulation: Kyakkyawan aikin lantarki, shine madaidaicin kayan kwalliyar C-class, Layer na kauri na jarida zai iya toshe babban matsin lamba 1500V. Zazzabi ba ya shafar rufin wutar lantarki. Dielectric akai-akai da asarar dielectric suna da ƙasa a cikin kewayon mitar mita, kuma raguwar ƙarfin lantarki, ƙarfin juriya da juriya na baka suna da girma.

Acid-base: tsaka tsaki.
