Imboni Yensimbi kanye Nemboni Yokucubungula Amakhemikhali ibisebenzisa imikhiqizo yamashubhu e-fluoropolymer evela ezintweni ezifana ne-PTFE namapayipi iminyaka eminingi ukuze kudluliswe amakhemikhali adala kakhulu noma abolayo.Ngokuqhubekayo, ishubhu le-PTFE lithatha isikhundla sekhabhoni nokunye ukubhobhoza kwensimbi okuwohlokayo ngokushesha.Manje nasesikhathini esizayo, i-PTFE izoqhubeka nokusebenzela imboni ngezicelo ezibalulekile.
Izimfanelo Zamakhemikhali*: I-PTFE ayisebenzi kula makhemikhali alandelayo
| Amakhemikhali Angaphili | Amakhemikhali Aphilayo | Okunye |
| I-Aqua Regia | Utshwala | Uketshezi Lwebhayoloji |
| I-Hydrofluoric Acid | Esters | Amakha |
| I-Sulfuric Acid evuthayo | Ama-ketones | Ukudla |
| I-Chlorosulfuric Acid | I-Halogenated Organics ephezulu | Oyinki Wokuphrinta Nodayi |
| Ukubilisa iSodium Hydrooxide Solution | Izincibilikisi Ezimnandi | I-Low Level Radioactive Substances |
| I-Chlorine Gas | Ama-amines | Ama-oxidizers |
| I-hydrogen peroxide | Amafutha Ezimboni | |
| I-Acid Chlorides | ||
| Kuyashisa, I-Nitric Acid Evuthayo |
*Phakathi kwamakhemikhali kuphela aziwa ukuthi ahlasele i-PTFE izinsimbi ze-alkali ezincibilikisiwe nezisombululo zazo, i-chlorine trifluoride, ne-gaseous fluorine emazingeni okushisa aphakeme nezingcindezi.
Izimfanelo Zokushisa:
Amashubhu e-PTFE angakwazi ukumelana namazinga okushisa afika ku-680 °F isikhathi esilinganiselwe.* Ngaphansi kwezimo ze-cryogenic, i-PTFE ihlala iqinile kuze kube -320 °F.
*Ngaphezu kuka-500 °F, izakhiwo eziwumshini ziba isici esikhawulelayo
Izimfanelo zikagesi:
Ishubhu ye-PTFE inezinto zikagesi ezinhle kakhulu, eziboniswa ukungaguquguquki kwe-dielectric okuphansi okungu-2.1 phakathi -40 °F no-480 °F phakathi kwebanga lefrikhwensi lika-5 Hz kuya ku-10 GHz.
Ishubhu ye-PTFE iphinde ibe isivikelo esingcono kakhulu esinokumelana nendawo okungaphezulu kuka-3.6 X 1012 ohms (ngisho naku-100% umswakama ohlobene).
Amandla e-dielectric esikhathi esifushane asukela ku-500 volts/mil (1 mil = 10-3 in) ogqinsi olungaphezu kuka-100 mils ukuya ku-4000 volts/mil kumafilimu azacile kakhulu.
Izimfanelo ze-UV kanye Nemisebe*:
Ishubhu ye-PTFE inokumelana okuhle kakhulu kwe-UV kanye nesimo sezulu, enomkhawulo wethamo lemisebe ye-PTFE ku-2 – 7 X 104 rads.Ukungabikho komoyampilo kukhulisa ukumelana nemisebe ngesici okungenani esingu-10.*Ukumelana nemisebe ye-electron ne-gamma kubi kakhulu
Izimfanelo Zokugqoka Nezingxabano:
Ishubhu ye-PTFE inendawo eshelelayo futhi ebushelelezi, ene-coefficient emile yokungqubuzana okungu-0.08 no-500 psi load.
Izakhiwo ze-PTFE ziyenza ifaneleke ikakhulukazi ukusetshenziswa njengamaphedi okuthwala, ngaphansi kwezimo zomthwalo wejubane eliphezulu.Izibonelo amaphedi anamabhuloho, amaphedi asekela amapayipi, namaphedi okukhweza okukhiqiza izinto ezinzima.
