Zida zapamwamba zazitsulo zazitsulo za PTFE zokhala ndi mapaipi

Teflon alimbane chitoliro zovekera ndi zitsulo PTFE mtundu gulu gulu chitoliro zovekera, amene akhoza kukana asidi amphamvu ndi zamchere.
Chitoliro choyamba: PTFE alimbane odana ndi dzimbiri chitoliro zovekera pambuyo zaka ntchito kwenikweni, mwachindunji zimakhudza moyo wake utumiki ndi zinthu khola ntchito ndi kutentha, kuthamanga, TV, etc., zipangizo zabwino kwambiri ndi patsogolo kupanga ndondomeko ndi chitsimikizo cha khalidwe la PTFE alimbane mankhwala.
Mawonekedwe
1. Kutentha kwakukulu muzofalitsa zamphamvu zowononga, zimatha kukumana ndi kutentha kwa madigiri -60 ~ 200 madigiri, mumtundu uwu wa kutentha umatha kukumana ndi mankhwala onse.
2. Kukaniza kwa vacuum kungagwiritsidwe ntchito pansi pazimenezi, popanga mankhwala, nthawi zambiri chifukwa cha kuzizira, kutuluka kwa nthawi yaitali, valavu yapampu sikugwirizana ndi momwe zinthu zimayendera chifukwa cha chikhalidwe cha vacuum.
3. Kukaniza kwakukulu pakugwiritsa ntchito kutentha kwa kutentha, kumatha kupirira mpaka 3MPA yogwiritsira ntchito kupanikizika
4. Anti-permeation ntchito zabwino kwambiri PTFE utomoni, kupyolera patsogolo akalowa ndondomeko mu kachulukidwe mkulu, makulidwe okwanira a PTFE akalowa wosanjikiza, kuti mankhwala ali apamwamba odana permeability.
5. Njira yonse yopangira ndi sintering yazitsulo imathetsa vuto la kutentha ndi kuzizira kukulitsa chitsulo ndi fluorine, ndikupangitsa kuti ikwaniritse kukula kwa synchronous
6. Miyeso yokhazikika imatengedwa, makamaka kwa mapaipi ndi zida zomwe zimagwiritsidwa ntchito m'mapaipi a mankhwala, omwe amasinthasintha kwambiri ndipo amapereka mwayi waukulu woikapo ndi zina.
Ubwino wa anti-corrosion:
1. Kukana kutentha kwakukulu {gwiritsani ntchito kutentha kwa madigiri 260.
2. Asidi wamphamvu komanso kukana kwa alkali (pH 1 ~ 14)
3. Kumamatira kwabwino kwambiri {kupanikizika koyipa kumatha kufikira 0.09MPa, vacuum effect.
4. Moyo wautali wautumiki {Pansi pazikhalidwe zomwe zingagwiritsidwe ntchito kwa zaka 8 mpaka 10, ndipo nthawi ya chitsimikizo nthawi zambiri imalonjeza kukhala 1 chaka.
5. Kukana mwamphamvu kulowa {hydrofluoric acid.Mpweya wa chlorine.Bromofluoric acid ndi mpweya wina uli ndi mphamvu yokana kulowa mkati
Kachitidwe:
Magwiridwe: ntchito sing'anga -100 ℃ ~ -250 ℃
Kuthamanga kwapakatikati: kuthamanga kwabwino: -2.5MPa, kukana kwapakatikati pa kutentha kwa 70KPa
Kukana dzimbiri: zitsulo polytetrafluoroethylene gulu gulu chitoliro zovekera, kuwonjezera zitsulo zitsulo lifiyamu, potaziyamu, sodium, chlorine trifluoride, mpweya trifluoride pa kutentha, mkulu otaya mlingo wa fluorine madzi, akhoza kukana pafupifupi onse mankhwala TV, kuphatikizapo anaikira nitric asidi ndi aqua regia dzimbiri, akhoza kugwira ntchito pa 230 ℃ - 250 ℃ kutentha kwa nthawi yaitali.Chitsulo polyvinylidene fluoride kalasi kapena vinylidene fuloride gulu gulu chubu, kuti halogen, halogenated hydrocarbons, amphamvu okosijeni, otentha asidi, alkali, zosiyanasiyana zosungunulira organic ndi zabwino dzimbiri kukana, koma osati fuming sulfuric acid, anaikira otentha sulfuric acid ndi asidi nitric, 90 ℃ pamwamba pa ketone, ester, amine ndi kutentha kwa sulfonated wothandizira dzimbiri.
Ubwino:
Kukana kutentha kwakukulu - gwiritsani ntchito kutentha mpaka 250 ℃.
Kukana kutentha kwapansi - kulimba kwa makina abwino;ngakhale kutentha kutsika mpaka -196 ° C, kutalika kumatha kusungidwa pa 5%.
Kulimbana ndi dzimbiri - kusagwirizana ndi mankhwala ambiri ndi zosungunulira, kugonjetsedwa ndi asidi amphamvu ndi alkalis, madzi ndi zosungunulira zosiyanasiyana zamoyo.
Kulimbana ndi nyengo - imakhala ndi moyo wokalamba wabwino kwambiri kuposa pulasitiki iliyonse.
Wothira mafuta kwambiri - chotsitsa chotsika kwambiri cha kukangana kwa chinthu chilichonse cholimba.
Zosamatira - zimakhala ndi kupsinjika kwapansi kwambiri kwa zinthu zilizonse zolimba ndipo sizimamatira kuzinthu zilizonse.
Zopanda poizoni - zopanda poizoni kwa zamoyo
Kugwiritsa ntchito mankhwala:
Chitsulo alimbane PTFE chitoliro zovekera ntchito: oyenera mpweya zikuwononga kwambiri ndi zakumwa pa kutentha, mitundu ina ya zitsulo-pulasitiki gulu mapaipi ndi mipope zitsulo si oyenera kunyamula TV, zitsulo PTFE gulu.Chitoliro chophatikizika chikugwiritsidwa ntchito, chitsulo cha polyvinylidene fluoride kalasi yophatikizika chitoliro choyenera kunyamula media zowononga pa kutentha kwa -40 ℃ ~ +150 ℃.
Zitsulo zokhala ndi zitoliro za PTFE zophatikizika, pogwiritsa ntchito njira zolimba zolimba, zosagwirizana ndi kukakamiza koyipa ndi vacuum, kuumba kopanda nsonga, kosalala komanso kolimba, kopanda kozungulira.Kuphatikiza sikugwa.Amagwiritsidwa ntchito kwambiri mumagetsi, makampani opanga mankhwala, zinthu za petrochemical, kuteteza chilengedwe ndi mafakitale ena.
