Polytetrafluoroethene,mwachidule:PTFE
Dzina lina: PTFE, tetrafluoroethylene, pulasitiki mfumu, F4.
Ubwino wa PTFE
PTFEndi mapulasitiki apadera a uinjiniya, pakali pano ndi zida zolimbana ndi dzimbiri, zomwe zimadziwika kuti "mfumu ya pulasitiki".Zinthu zazikuluzikulu ndizokwera komanso kutsika kwa kutentha, kukana kwa dzimbiri, kutsekemera kwakukulu, kukana kukalamba, kudzipaka mafuta.
Amagwiritsidwa ntchito muzamlengalenga, zamagetsi ndi zida zamagetsi, makampani opanga mankhwala, makina ndi zida, chakudya ndi zamankhwala, mapampu, mavavu ndi mapaipi, magalimoto ndi zombo, ma compressor a mpweya, ndi zina zambiri, ndipo wakhala chinthu chofunikira kwambiri pakuthana ndi matekinoloje ambiri amakono. makampani.
PTFE molekyulu inert F maatomu kutchinga ndi kuteteza CC chomangira, ndi CF kugwirizana mphamvu makamaka khola, unyolo maselo n'zovuta kuwonongedwa, ndi dongosolo khola kwambiri.Kapangidwe ka maselo kameneka kamafotokozanso zinthu zotsatirazi zabwino kwambiri za PTFE.
Kulimbana ndi corrosion:Kuphatikiza pa zitsulo zosungunula za alkali ndi zosungunulira zochepa monga ma alkane hydrocarbons opitilira 300 digiri Celsius, imalimbana ndi dzimbiri kwanthawi yayitali ndi mankhwala ena aliwonse.
Kukana kutentha kwambiri ndi otsika: angagwiritsidwe ntchito kwa nthawi yaitali pa -60+260 ℃.
Kupaka mafuta kwambiri:kagawo kakang'ono kwambiri ka mikangano pakati pa zinthu zolimba, ngakhale ayezi sangafanane nawo.
Kusamamatira:Kukakamira kochepa kwambiri pakati pa zinthu zolimba, sikumamatira ku chinthu chilichonse.
Kukaniza Nyengo:Moyo wokalamba kwambiri pakati pa mapulasitiki.
Zopanda poizoni:zinthu angagwiritsidwe ntchito ngati yokumba Mitsempha, sanali poizoni ndi sanali matupi awo sagwirizana zochita ndi zina chokhwima, chakudya ndi mankhwala kalasi zipangizo.
Insulating katundu:filimu yokhuthala ngati nyuzipepala ndiyokwanira kukana magetsi okwera kwambiri a 1500V.
Komanso, PTFE komanso alibe mayamwidwe chinyezi, sanali flammability, ndipo kwambiri kwa mpweya, ultraviolet kuwala.
Zoyipa za PTFE
Ngakhale PTFE ali ndi ntchito zabwino kwambiri mabuku, koma otsika mphamvu mawotchi, coefficient lalikulu la kukula liniya, osauka kuvala kukana, osauka chikwawa kukana, osauka matenthedwe madutsidwe ndi zofooka zina.Mu mphamvu zamakina ndi zovuta zina, monga kugwiritsidwa ntchito pamakampani osindikizira ma valve ndi malire ake enieni ogwiritsira ntchito kutentha nthawi zambiri amakhala mkati -70 ~ +150 ℃.Pofuna kuthana ndi zophophonya izi, PTFE utomoni akhoza kudzazidwa ndi kulimbikitsa wothandizila kusintha makina katundu wa zinthu, pofuna kukulitsa kukula kwa ntchito zipangizo zake.
Chiyambi cha zida zamtundu wa PTFE
Mtundu wapachiyambi wa PTFE ndi wamkaka woyera, pamene wachikuda PTFE ndi chifukwa PTFE m'munsi zakuthupi ndi wodzazidwa ndi zipangizo wothandiza.Zida zothandizira zitha kugawidwa m'magulu awiri molingana ndi kugwiritsa ntchito: zowonjezera zowonjezera ndi mtundu wa ufa.
Mtundu ufa wothandizira kalasi: wodzazidwa ndi mtundu ufa PTFE, akhoza momasuka wakuda, wachikasu, wofiira, wobiriwira, buluu ndi zina zotero.Mtundu ufa wothandizira ndi kokha kusintha mtundu wa PTFE, chiŵerengero cha filler ndi pang'ono kuti zotsatira za ntchito PTFE choyambirira akhoza kunyalanyazidwa.Mwachidziwitso, mtundu wa ufa wothandizira uyenera kukhudza kukhazikika kwa mankhwala a PTFE, kusungunula, mphamvu zamakina ndi zina zamakina.Chifukwa chake, zochitika zina zapadera ziyenera kuzindikila.Wakuda PTFE amakwaniritsa zofuna za makasitomala omwe ali ndi zofunikira pamitundu yowoneka.
Kugula machubu olondola a PTFE sikuti amangosankha mitundu yosiyanasiyana yamapulogalamu osiyanasiyana.Zambiri kusankha wopanga wodalirika.BesteflonFluorine plastic Industry Co., Ltd. imakhazikika pakupanga kwapamwamba kwambiriZithunzi za PTFEndi machubu kwa zaka 20.Ngati aliyense ptfe chubu mafunso ndi zosowa, chonde omasuka kutifunsa kuti mudziwe zambiri akatswiri.
