Kwimitha yokuhamba kwe-electromagnetic, zeziphi iimeko zokusebenza ezifanelekileyo ngokulandelelana kwi-lining yerabha, i-lining ye-PTFE kunye ne-lining ye-PFA?

1. Irabha (Yendalo/I-Neoprene/CR)
Eyona ilungele: Ukusetyenziswa ngokubanzi, ukugqwala okuphantsi ukuya kokuphakathi, imithombo yamanzi, kunye nodaka olunokugqwala okuncinci.
Ubushushu: Ngokwesiqhelo - 10 °C ukuya ku +80 °C (uhambo olufutshane ukuya ku-90 °C).
Ukugqwala: Iyamelana namanzi acocekileyo, amanzi amdaka, amanzi olwandle, amanzi amdaka, ii-acids/bases ezibuthathaka (pH 4–10), kunye neeoyile.
Ukurhawuzelelwa: Kuphakathi; kufanelekile kwi-slurry ethambileyo, i-pulp yephepha, i-mine tailings (izinto eziqinileyo eziphantsi).
Uxinzelelo: Ukuya kuthi ga kwi-PN16–PN25 (1.6–2.5 MPa).
Imida: Ayizizo ii-asidi ezinamandla, iziseko ezinamandla, izinyibilikisi, okanye ubushushu obuphezulu; ziyadumba kwii-hydrocarbons.
Amashishini: Amanzi/amanzi amdaka, oomasipala, i-HVAC, inkqubo ngokubanzi, ukumbiwa kwemigodi (ukuguguleka okuncinci).
2. I-PTFE (iPolytetrafluoroethylene, iTeflon®)
Eyona ilungele: Imithombo yeendaba edla ngokuba yingozi kakhulu, ubushushu obuphezulu, kunye nolwelo olungarhawuzeliyo.
Ubushushu: ‑40 °C ukuya ku-+130 °C (eqhelekileyo); ‑200 °C ukuya ku-+200 °C (ixesha elikhawulezileyo, elilinganiselweyo).
Ukubola: Igqwesile—imelana nee-asidi ezixineneyo (HCl, H₂SO₄, HNO₃), iziseko eziqinileyo (NaOH, KOH), ii-oxidizers (NaClO, H₂O₂), kunye nezinye izinyibilikisi ezininzi zendalo.
Ukurhawuzelelwa: Kubi—kuphephe izinto eziqinileyo, isanti, okanye amasuntswana aqinileyo.
Uxinzelelo: Ukuya kuthi ga kwi-PN25 (2.5 MPa); hayi uxinzelelo olungenasikhephe/olungelulo (umngcipheko wokuwa).
Imida: Ukubhitya, ukumelana nokukrweleka okuphantsi, ukunganyamezelani kakuhle ne-vacuum; ihlaselwa ziintsimbi ze-alkali ezinyibilikisiweyo, igesi ye-fluorine, i-ClF₃.
Amashishini: Ukucubungula iikhemikhali, i-petrochemical, amayeza, i-plating, amanzi amdaka (agqwala kakhulu).
3. I-PFA (i-Perfluoroalkoxy, “i-PTFE eguquliweyo”)
Eyona ilungele: Ubunyulu obuphezulu, ubushushu obuphezulu, kunye nokusetyenziswa okutsha kakhulu (phucula ngaphezulu kwe-PTFE).
Ubushushu: -40 °C ukuya ku +180 °C (okuqhubekayo); iincopho ezimfutshane ukuya kuma-200 °C.
Ukugqwala: Ilingana ne-PTFE—imelana nazo zonke izixhobo ezihambelana ne-PTFE; ukuvuza kwe-ion yesinyithi ephantsi kakhulu (<1 ppb).
Ukukrala: Ingcono kune-PTFE (isephakathi); ifanelekile kwizinto eziqinileyo eziphantsi ukuya kweziphakathi.
Uxinzelelo: Ukuya kuthi ga kwi-PN40 (4.0 MPa); ukumelana okuhle kakhulu koxinzelelo lwe-vacuum/negative.
I-Mechanical: Iguquguquka, iqinile, ayishukumi; inokubotshelelwa kubushushu kwityhubhu (akukho kususwa kwe-demination); ukhetho olucacileyo/olukhanyayo luyafumaneka.
Ukuthobela imithetho: i-FDA, i-3‑A, i-EHEDG, i-ASME BPE (imigangatho yococeko/yobunyulu obuphezulu).
Imida: Ixabiso eliphezulu (3–5× PTFE); iikhemikhali ezifanayo nezingafaniyo nePTFE.
Amashishini: I-Semiconductor (amanzi/iikhemikhali ezicocekileyo kakhulu), i-biotech/amayeza (angenazintsholongwane/i-CIP/SIP), ukutya/isiselo (ukucoca ulwelo olushushu kakhulu), ii-solar, kunye neenkqubo zeekhemikhali eziphambili.
