Emkhakheni wezinto zepulasitiki,I-PTFE(i-polytetrafluoroethylene) ivelele njengesixazululo esihle kakhulu nesiguquguqukayo sezinhlelo zokusebenza ezahlukahlukene. Ngezakhiwo zayo ezinhle kakhulu kanye nohlu olubanzi lwezinhlelo zokusebenza, isibe yinto ebalulekile ezimbonini ezahlukahlukene. Kulesi sihloko sebhulogi, sizohlola izakhiwo kanye nezinzuzo zezinduku ze-PTFE, ezitholakala kokubili ngezindlela ezikhishwe kanye nezibunjiwe.
Kusukela ngezinhlobo ezikhishwe ngaphandle, lezi zinduku zenziwa ngosayizi abajwayelekile, kusukela ku-1/8" ububanzi kuya ku-8". Ubude obujwayelekile benduku ekhishwe ngaphandle ye-PTFE bungaba ngu-1000mm, okwenza kube lula kakhulu. Ngakolunye uhlangothi, ezikhishwe ngaphandleInduku ye-PTFEAma-s atholakala ngobubanzi obufika kuma-intshi angu-16 kanye nobude obuphezulu obungu-300 mm. Izinketho eziningi zosayizi ziqinisekisa ukuthi amakhasimende angathola umkhiqizo ofanelana kahle nezidingo zawo ezithile.
Enye yezinzuzo ezibalulekile ze-Induku ye-PTFEI-s iwukusebenza okuthuthukisiwe ngokusebenzisa izinto zokugcwalisa (ukuqinisa). Lezi zinduku zingenziwa ngezinto ezahlukene zokuqinisa ezifana ne-fiberglass, i-graphite kanye ne-bronze. Lezi ziqinisekiso zithuthukisa kakhulu izakhiwo ze-PTFE, okwenza kube ukukhetha okufanele kwezicelo ezidinga amandla.
Ukumelana nesimo sezulu kungenye yezimpawu eziyinhloko zezinduku ze-PTFE, le nto inempilo engcono kakhulu yokuguga phakathi kwepulasitiki. Lokhu kusho ukuthi izinduku ze-PTFE zingamelana nezimo zezulu ezinzima ngaphandle kokulahlekelwa yizimfanelo zazo noma ukonakala ngokuhamba kwesikhathi. Ngaphezu kwalokho,Induku ye-PTFEAma-s anokumelana okuhle kakhulu nokugqwala, okwenza afaneleke kakhulu ekusetshenzisweni okuhlanganisa ama-asidi aqinile, izisekelo, amanzi, kanye nezinyibilikisi ezahlukahlukene zezinto eziphilayo.
Esinye isici esiphawulekayo sezinduku ze-PTFE ukuthamba kwazo okuphezulu, okubhekwa njengokuthamba okuphansi kakhulu phakathi kwamapulasitiki. Njengoba i-coefficient yokuthamba iphansi njengo-0.04, izinduku ze-PTFE zinikeza ukuthamba okuhle kakhulu, kunciphisa ukuguguleka futhi kuqinisekiswe ukusebenza kahle ezinhlotsheni ezahlukene zokusebenza.
Enye yezindawo lapho i-PTFE ikhanya khona ngempela yikhono layo lokubekezelela amazinga okushisa aphezulu.Induku ye-PTFEAma-s angamelana namazinga okushisa esikhathi eside angama-degree Celsius angama-200 kuya kwangu-260, okwenza afaneleke ukusetshenziswa ezindaweni ezishisa kakhulu. Lokhu kumelana nokushisa okuphezulu kuthuthukisa ukuthembeka nokuqina kwezinduku ze-PTFE.
Ngokuphambene nalokho, izinduku ze-PTFE nazo zibonisa ukusebenza okuhle kakhulu emazingeni okushisa aphansi. Ngisho noma izinga lokushisa lehla liye kuma-degree Celsius angu-196, induku ye-PTFE isakwazi ukugcina ubude obungu-5%, ikhombisa ukuguquguquka kwayo okuhle kakhulu kanye nokunwebeka ngaphansi kwezimo ezibandayo kakhulu.
Ngaphezu kwalokho, izinduku ze-PTFE zingaqoshwa ngezinjongo zokubopha, okuvumela ukuxhumana okuphephile kanye nokuguquguquka kwesicelo okwandisiwe. Lesi sici senza izinduku ze-PTFE zilungele amaphrojekthi ahlukahlukene esakhiwo kanye nobunjiniyela.
Ekuphetheni, izinduku ze-PTFE ziyisisombululo esiguquguqukayo nesithembekile esinezakhiwo ezimangalisayo. Zitholakala kokubili ngezindlela ezikhishwe kanye nezibunjiwe, kanye nezinketho ezahlukene zosayizi, okuvumela ukuguquguquka ukuhlangabezana nezidingo ezahlukene zohlelo lokusebenza. Ukusebenza okuthuthukisiwe okufezwa yizinto zokuqinisa kwandisa ububanzi bokusetshenziswaIzinduku ze-PTFEKusukela esimweni sezulu kanye nokumelana nokugqwala kuya ekugcobeni okuphezulu, ukumelana nokushisa kanye nokusebenza okukhanyayo, izinduku ze-PTFE zinikeza inhlanganisela yezimfanelo ezingenakuqhathaniswa. Ngakho-ke noma ngabe udinga izinto ezithembekile zokusetshenziswa kwesakhiwo, imboni yamakhemikhali, noma okunye, cabanga ngezinduku ze-PTFE ngokusebenza kwazo okuhle kakhulu kanye nokuqina okuhlala isikhathi eside.
