Ptfe coating ngensimbi engenasici

Ukuqalisa

I-PolytetraFbuoroethylene (PTFE) Coating, edume ngokumelana kwayo okuhlukile kwamakhemikhali, izakhiwo ezingezona izinti, kanye nokuqina okushisayo, kuya ngokuya kufakwa kwi-mesh engenasici ukuthuthukisa ukusebenza kwezimboni. Le nhlanganisela ifaka amandla enhlaka yensimbi engenacala nge-PTFE engaphezulu kokusebenza komhlaba, okunikeza isisombululo esiguquguqukayo sokuhlunga, ukwahlukana kanye nokuvuka-okubonakalayo.

Inqubo yokuhlanganisa

1.Ukulungiselela okungaphezulu

I-mesh engagqwali iqhuma ukuqhuma noma ukugcwala kwamakhemikhali ukuqinisekisa ukunamathela okuphelele.

Ukuhlanza kususa uwoyela, oxides, kanye nokungcola.

2.Ukufafaza kwe-PTFE

Inqubo: Ukufafaza nge-electrostatic noma ukumiswa kwe-coating kufakwa ungqimba lwe-ptfe olufanayo (ngokuvamile 10-50 μm).

Ukwelapha: Ukwelashwa kokushisa ku-350-400 ° C.

Ukulawulwa kwamalungiselelo

Ukulinganisa kokuqina, ukuhlolwa kokunamathela (isib.

Izinzuzo ezibalulekile

1.Ukuthuthukiswa kwamakhemikhali okuthuthukisiwe

Ibekezelela ama-acid, ama-alkali, nama-solvents (isib. Hl, HCL, NAOH), elungele ukuhlunga kwamakhemikhali nokuphathwa koketshezi okulimazayo.

I-2.Non-stick ebusweni

Kuvimbela ukuvela ezintweni ezinama-viscous (uwoyela, anamathela), kunciphisa ukulungiswa ezinhlelweni zamanzi okuhlukanisa amanzi.

3.Ukuqina okushisayo

Isebenza ngokuqhubekayo ukusuka ku-200 ° C kuya ku- + 260 ° C, ilungele ukuhlunga okushisa okuphezulu (isib. Izinhlelo zokuphelelwa amandla, oveni wezimboni).

4.Ukuqina okuthuthukisiwe

I-PTFE ivikela ngokumelene nokuwohloka kwe-abrasion kanye ne-UV, yandisa i-Mesh LifeSpan ngo-3-5 × uma iqhathaniswa nokuhlukahluka okungagunyaziwe.

5.Izakhiwo zeHydrophobic

Ukhipha amanzi ngenkathi evumela ukufundisa uwoyela, ukwenza kahle izinhlelo zokusebenza zophethiloli / wamanzi.

Izinja

1.Ukuhlukaniswa kwamanzi

Izihlungi ze-PTFE-Cated ezihlungi zama-coalescing zithuthukisa ukusebenza kahle kokuhlukanisa (> 95%) kwizimboni zasolwandle, zezimoto, kanye ne-wastewater.

2.Ukuhlunga kwamakhemikhali

Yenqaba imithombo yezindaba enolaka ekukhiqizweni komkhandlu, kwe-petrochemical, kanye nokwenziwa kwe-semiconductor.

3.Ukusebenza kokudla

Ama-Coatings ahambisana ne-FDA avimbela ukunamathela kwezithako ezinamathelayo (isib.

4.I-Aerospace & Energy

Isetshenziswa ku-Fuel Cell Mempranes kanye nokuphelelwa amandla igesi ngenxa yokuqina okushisayo nangokwekhemikhali.

Isifundo secala: Ukusebenziseka kahle kwezimboni

Iklayenti emkhakheni we-biodiesel lisebenzisa i-PTFE-cameras 316l yensimbi mesh (80 μm) ukubhekana nokuhlukaniswa kwamanzi ama-methanol. Imiphumela ye-post-coating ifakiwe:

Izikhathi ezi-30% ezinde zokusebenzela(inciphise i-fouling).

I-20% ephakeme ephakeme(Ukuthembeka kwe-Pore Ubuqotho).

Ukuhambisana namazinga we-ASTM F719 wokuvezwa kwamakhemikhali.

Ukucatshangelwa Kwezobuchwepheshe

Mesh Ukuvumelana: Ilungele ama-apertures angama-50-500 ama-micron; ukumbona okukhulu kunganciphisa amanani okugeleza.

Ukwenza ngokwezifiso: Imbobo ye-gradient noma izinto ezi-hybrid (isib.

Ukugcina

I-PTFE-CAED MET MESW Mesh ihlanganisa ukuqina kwemishini ngezakhiwo ezisezingeni eliphakeme, ukuletha izixazululo ezingenziwa eziyazindleko, isikhathi eside sezindawo ezinzima zokusebenza. Ukuzivumelanisa nezimo zayo ezimbonini kugcizelela indima yayo njengokuqamba izinto ezibalulekile ekwakhekeni kwanamuhla.
