Chifukwa chiyani amatchedwa ptfe chubu?Kodi limatchedwa bwanji ptfe chubu?
Polytetrafluoroethylene chubu amatchedwansoPTFE chubu, yomwe imadziwika kuti "Pulasitiki King", ndi polima wapamwamba kwambiri wokonzedwa ndi polymerizing tetrafluoroethylene ngati monomer.Waxy woyera, translucent, kutentha kwambiri ndi kukana kuzizira, angagwiritsidwe ntchito kwa nthawi yaitali pa -180 ~ 260ºC.Nkhaniyi ilibe inki kapena zina, ali makhalidwe kukana asidi, zamchere, ndi zosiyanasiyana zosungunulira organic, ndipo pafupifupi insoluble mu zosungunulira zonse.Pa nthawi yomweyo, PTFE ali makhalidwe a mkulu kutentha kukana, ndi mikangano koyefilanti ndi otsika kwambiri, choncho angagwiritsidwe ntchito kondomu ndi kukhala ❖ kuyanika abwino kuyeretsa mosavuta wosanjikiza wamkati wa mipope madzi.
Njira yopangira:
The zopangira PTFE chubu ndi ufa ndipo akhoza kupangidwa ndi psinjika kapena extrusion processing
Mtundu wa chubu:
1.Smooth bore chubing amapangidwa kuchokera kwa namwali 100% PTFE utomoni wopanda pigment kapena zowonjezera.Ndizoyenera kugwiritsidwa ntchito mu Aero space & Transportation Technology, Electronics, Components & Insulators, Chemical & Pharmaceutical Manufacturing, Food Processing, Environmental Sciences, Sampling Air, Fluid Transfer Devices ndi Water Processing Systems.Anti-static(Katoni) kapena mitundu yamitundu yamachubu onse ilipo.
2.Convoluted chubu amapangidwa kuchokera namwali 100% PTFE utomoni popanda pigment kapena zowonjezera.Imakhala ndi kusinthasintha kwabwino komanso kukana kwa kink kuti igwire bwino ntchito pomwe mapindikidwe opindika ocheperako, kupatsirana kowonjezereka kapena kukana kumafunikira.Machubu opindika amatha kuyatsidwa ndi ma flares, flanges, cuffs, kapena kuphatikiza kopitilira imodzi Optimized Tubing Solution.Mitundu ya anti-static (carbon) yamachubu onse ilipo.
3.Capillary chubu Makhalidwe a kutentha ndi kukana kwa dzimbiri kwa machubu a capillary akhala akugwiritsidwa ntchito kwambiri m'mafakitale oletsa kutupa, monga mafakitale a mankhwala, pickling, electroplating, mankhwala, anodizing ndi mafakitale ena.Chubu cha capillary chimakhala ndi kukana bwino kwa dzimbiri, kukana kwabwino, kukana kukalamba bwino, kusuntha kwabwino kwa kutentha, kukana pang'ono, kukula kochepa, kulemera kopepuka komanso kapangidwe kake.
Katundu ndi kukhazikika:
1.Kutentha kwakukulu kukana, osasungunuka muzitsulo zilizonse.Imatha kupirira kutentha kwambiri mpaka 300 ℃ pakanthawi kochepa, ndipo itha kugwiritsidwa ntchito mosalekeza pakati pa 240 ℃ ~ 260 ℃, ndipo imakhala ndi kukhazikika kodabwitsa kwamatenthedwe.Kuphatikiza pa kuchitapo kanthu ndi zitsulo zosungunuka za alkali, sizimawonongeka ndi zinthu zilizonse, ngakhale zitawiritsidwa mu hydrofluoric acid, aqua regia kapena fuming sulfuric acid, sodium hydroxide, sizisintha.
2.Low kutentha kukana, zabwino makina kulimba pa kutentha otsika, ngakhale kutentha akutsikira -196 ℃ popanda embrittlement, akhoza kusunga 5% elongation.
3.Corrosion resistance, inert kwa mankhwala ambiri ndi zosungunulira, kugonjetsedwa ndi zidulo amphamvu ndi alkalis, madzi ndi zosiyanasiyana zosungunulira organic, ndipo akhoza kuteteza mbali ku mtundu uliwonse dzimbiri mankhwala.
4.Anti-aging, pansi pa katundu wambiri, ali ndi ubwino wapawiri wa kukana kuvala ndi kusamata.Ili ndi moyo wokalamba wabwino kwambiri mu mapulasitiki.
5.Kupaka mafuta, komwe kumakhala kocheperako kocheperako pakati pa zinthu zolimba.Mkangano wa coefficient umasintha pamene katundu akutsetsereka, koma mtengo umangokhala pakati pa 0.05-0.15.
6. Kusamamatira, komwe kumakhala ndi kugwedezeka kochepa kwambiri pamtunda pakati pa zinthu zolimba, ndipo sikumamatira ku chinthu chilichonse.Pafupifupi zinthu zonse sizimamatira kwa izo.Mafilimu oonda kwambiri amasonyezanso zinthu zabwino zopanda ndodo.
7.Ndi yoyera, yopanda fungo, yosakoma, yopanda poizoni, komanso yopanda physiologically.Monga chotengera chamagazi chochita kupanga ndi chiwalo choyikidwa m'thupi kwa nthawi yayitali, sichikhala ndi zotsatirapo zoyipa.
8.Kulemera kwakukulu ndi kusinthasintha kwamphamvu.Ikhoza kuchepetsa kwambiri mphamvu yogwira ntchito ya wogwiritsa ntchito.
9.Comprehensive ubwino wa mankhwala, kuti moyo utumiki kwambiri kuposa alipo mitundu yosiyanasiyana ya payipi nthunzi, ntchito nthawi yaitali safuna m'malo, kuchepetsa kwambiri mtengo ntchito, kusintha ntchito Mwachangu, zachuma ndi zothandiza.
Malo ofunsira:
Amagwiritsidwa ntchito m'makampani amagetsi
muzamlengalenga, ndege, zamagetsi, zida, makompyuta ndi mafakitale ena monga kutchinjiriza wosanjikiza wa mphamvu ndi mizere chizindikiro, dzimbiri zosagwira ndi kuvala zosagwira zipangizo angagwiritsidwe ntchito kupanga mafilimu, mapepala chubu, fani, washers, mavavu ndi mapaipi Chemical , zovekera chitoliro, zida chidebe linings, etc
Amagwiritsidwa ntchito pazida zamagetsi
makampani mankhwala, ndege, makina, etc. m'malo quartz glassware, ntchito kopitilira muyeso-woyera mankhwala kusanthula ndi kusunga zidulo zosiyanasiyana, alkali, ndi zosungunulira organic mu mphamvu atomiki, mankhwala, semiconductor ndi mafakitale ena.Itha kupangidwa kukhala zida zamagetsi zokhala ndi zotsekemera kwambiri, waya wothamanga kwambiri komanso kukhetsa chingwe, ziwiya zamankhwala zosagwira dzimbiri, mapaipi amafuta ozizira kwambiri, ziwalo zopangira, etc. zitha kugwiritsidwa ntchito ngati zowonjezera mapulasitiki, mphira, zokutira, inki, mafuta, mafuta, etc
Izi zimagonjetsedwa ndi kutentha kwakukulu ndi dzimbiri
ili ndi zotchingira bwino kwambiri zamagetsi, kukana kukalamba, kuyamwa kwamadzi pang'ono, komanso ntchito yabwino yodzipaka mafuta.Ndi ufa wapadziko lonse wothira mafuta oyenerera pazofalitsa zosiyanasiyana ndipo ukhoza kugwiritsidwa ntchito mwachangu kupanga filimu yowuma , Kuti agwiritsidwe ntchito m'malo mwa graphite, molybdenum ndi mafuta ena osakhazikika.Ndiwotulutsa nkhungu yoyenera ma polima a thermoplastic ndi thermosetting okhala ndi mphamvu yabwino yonyamula.Amagwiritsidwa ntchito kwambiri mumakampani a elastomer ndi labala komanso anti-corrosion
Imagwiritsidwa ntchito ngati chodzaza ndi epoxy resin kuti ipititse patsogolo kukana kwamphamvu, kukana kutentha komanso kukana kwa dzimbiri kwa zomatira za epoxy.
Amagwiritsidwa ntchito makamaka ngati chomangira ndi chodzaza ndi makeke a ufa
