PTFF wophatikiza ndi chitsulo chosapanga dzimbiri

Chiyambi

Polytetrafluoro solmblene (PTF) akukutira, kutchuka chifukwa cha kukana kwa mankhwala, osakhazikika, komanso kukhazikika kwamatenthedwe, ndi kukhazikika kwa matenthedwe, kumagwiritsidwa ntchito kwambiri pamwambo wosapanga dzimbiri. Kuphatikiza uku kumalepheretsa chitsulo chosapanga dzimbiri ndi magwiridwe antchito a Ptyfe, kupereka yankho losinthasintha kufesa, kudzipatula, komanso kugwiritsa ntchito kolowera.

Njira Zokutira

1.Kukonzekera Komka

Miphika yosapanga dzimbiri yomwe ili pansi yophulika kapena yopanga mankhwala kuti iwonetsetse zomatira zabwino.

Kuyeretsa kumachotsa mafuta, oxides, ndi zodetsa nkhawa.

2.PTFF akupopera

Njira: Kuchulukitsa kwa magetsi kapena zolumikizira zolumikizira zimayika osanjikiza a PTF (nthawi zambiri 10-50 μm).

Kuchiritsa: Chithandizo cha kutentha nthawi ya 350-400 ° C wochimwa, ndikupanga filimu yonyowa.

3.Kuwongolera

Kukula kwa makulidwe, kuyesa kwa Adeteion (mwachitsanzo, kudutsa a ASTM D3359), komanso kuyendera kopepuka kuwonetsetsa kuti kudalirika.

Ubwino Wofunika

1.Kukulitsa mankhwala kukana

Tikuthamangitsa acid acid, alkalis, ndi ma sol sol (mwachitsanzo, HCL, Naoh), yabwino kusokoneza mankhwala ndi madzi osokoneza bongo.

2.non-ndodo

Imalepheretsa kufooka kuchokera ku zinthu za ma viscous (mafuta, zomatira), kuchepetsa kusamalira m'madzi olekanitsidwa ndi madzi.

3.Kukhazikika kwa mafuta

Imagwira ntchito mosalekeza kuchokera -200 ° C kuti + 260 ° C, yoyenera kusefa (mwachitsanzo, njira zolimbikitsira, uvuni wa mafakitale).

4.Kukhazikika Kwabwino

PTF imateteza ku Abrasion ndi UV kuwonongeka, kufalitsa mitu yopatsa anthu 3-5 ng × poyerekeza ndi kusiyanasiyana kosavomerezeka.

5.Mphamvu ya Hydrophobic

Imabweza madzi ndikulola kulolera kwa mafuta, kukwaniritsa bwino kwa mafuta / madzi olekanitsa.

Mapulogalamu

1.Kupatukana kwamadzi

Ma mesani okhala ndi ma ptfe okhala ndi zosefera zowoneka bwino amasintha mphamvu yolekanitsa (> 95%) ku Marine, maoto automive, ndi mafakitale.

2.Kusamba kwa Chemical

Imaletsanso media yazambiri mu mankhwala ogulitsa, petrochemical, ndi kupanga semiconduc.

3.Kukonza chakudya

Zovala za FDA - Zogwirizana zimalepheretsa zomata za zosakaniza (mwachitsanzo, mtanda, shuga) mu malamba kapena misampha.

4.Aerospace & Mphamvu

Amagwiritsidwa ntchito mu membranes ya mafuta ndi mafuta otulutsa mpweya chifukwa cha mphamvu yamafuta ndi mankhwala.

Phunziro la Mlandu: Kutsatsa kwa mafakitale

Kasitomala mu gawo la biodiesel adagwiritsa ntchito katatu wa PTFE 36L Dongosolo la Chitsulo (80 μm) kuti atchule zolekanitsa m'madzi a methanol. Zotsatira zokutira pambuyo pake zophatikizidwa:

30% yayitali nthawi zonse(ochepetsedwa).

20% Okwera(Kulimbikitsidwa kukhulupirika).

Kutsatira ndi miyezo ya ASM F719 ya kuwonekera kwa mankhwala.

Maganizo aluso

Kuphatikizika kwa ma mesh: Zoyenera za ma perter a 50-500 micron; Kukumba kwamphamvu kumachepetsa mitengo.

Kusinthasintha: Zovala za Gradient kapena zida za hybrid (mwachitsanzo, PTF + PFA) imatha kuthana ndi zosowa zapadera kapena zamagetsi.

Mapeto

Misambo yophika yopanda dzimbiri imabalakira mofatsa yamagetsi yokhala ndi malo okwera kwambiri, kupereka njira zokwanira, zothetsera mavuto, njira zazitali za malo ankhanza ogwira ntchito. Mafakitale awo kudutsa ma mafakitale amatsikira gawo lake monga njira yovuta kwambiri yaukadaulo yamakono.
