Kodi ptfe hose ndi chiyani |Malingaliro a kampani BESTEFLON

Kodi mudamvapo za PTFE ndiPTFE hose?Chabwino, tiyeni tione ngati tingayankhe mafunso ena okhudza izo.

Polytetrafluoroethylene (polytetrafluoroethylene) ndi chidule cha PTFE, chomwe chimadziwika kuti "pulasitiki mfumu", ndipo dzina lake la malonda ndi Teflon.Ku China, chifukwa cha matchulidwe, "TEFLON" amadziwikanso kuti Teflon, onse omwe amamasulira Teflon.Polytetrafluoroethylene amadziwika kuti "mfumu ya mapulasitiki", bambo wa fluororesin Roy Planck 1936 DuPont kampani ku United States anayamba kuphunzira m'malo Freon.Anasonkhanitsa tetrafluoroethylene ndikusunga mu masilindala kuti adzayeserenso tsiku lotsatira.Komabe, pamene valavu yochepetsera mphamvu ya silinda inatsegulidwa tsiku lotsatira, palibe mpweya umene unasefukira.Iwo ankaganiza kuti watha, koma poyeza silindayo, anapeza kuti silindayo sinaonde.Anawona kupyolera mu silindayo ndipo adapeza ufa wambiri woyera, womwe ndi polytetrafluoroethylene.Adapeza kuti polytetrafluoroethylene ili ndi zinthu zabwino kwambiri ndipo imatha kugwiritsidwa ntchito ngati anti melting sealing gasket pama bomba a atomiki ndi zipolopolo.Chifukwa chake, asitikali aku US adasunga chinsinsi chaukadaulo pa Nkhondo Yachiwiri Yapadziko Lonse.Sizinali mpaka kumapeto kwa Nkhondo Yachiwiri Yadziko Lonse pomwe idasinthidwa ndikusinthidwa kukhala mafakitale mu 1946.PTFE mzere wa hose, PTFE malata paipi

Polytetrafluoroethylene akhoza kupangidwa ndi psinjika kapena extrusion;itha kupangidwanso kukhala madzi amwazikana kuti azitikita, kulowetsedwa kapena ulusi.Polytetrafluoroethylene (PTFE) chimagwiritsidwa ntchito m'mafakitale a atomiki mphamvu, chitetezo dziko, zamlengalenga, zamagetsi, magetsi, mankhwala zomangamanga, makina, zida, zida, zomangamanga, nsalu, zitsulo pamwamba mankhwala, mankhwala, mankhwala, nsalu, chakudya, zitsulo ndi mafakitale osungunula, ndi zina zotero, zomwe zimapangitsa kukhala chinthu chosasinthika.

PTFE ndiye chidule cha polytetrafluoroethylene - ndi liwu lalitali, koma lalitali liyenera kutanthauza kuti ndilabwino!Dzina lachizindikiro cha polytetrafluoroethylene ndi dzina lodziwika kwambiri la polytetrafluoroethylene.

Chifukwa chiyani payipi ya polytetrafluoroethylene (PTFE) imagwiritsidwa ntchito mu chitoliro cha inkjet cha chosindikizira cha 3D, chitoliro chodyetsera cha makina a khofi, chitoliro choziziritsa madzi ndi chitoliro cha chitoliro cha brake?

1) PTFE chubu ali mkulu mankhwala bata ndi kupirira zochita za zidulo amphamvu onse, kuphatikizapo aqua regia, hydrofluoric acid, anaikira hydrochloric asidi, asidi nitric, fuming sulfuric acid, organic acid, m'munsi amphamvu, amphamvu oxidant, kuchepetsa wothandizila ndi zosiyanasiyana organic. zosungunulira.Amagwiritsidwa ntchito kwambiri popereka madzi amadzi osiyanasiyana.

2) Itha kugwiritsidwa ntchito kwa nthawi yayitali - 80 ℃ - + 280 ℃.Ikhoza kugwira ntchito pa kutentha kwachisanu popanda kusungunuka ndi kusungunuka pa kutentha kwakukulu.

3) Kuwoneka bwino kosawoneka bwino komanso kukhathamiritsa kwa anti ndikwabwino, ndipo khoma lamkati la chitoliro silimamatira ku colloids ndi mankhwala, kotero silingapange dothi mu chitoliro.

4) Ntchito yabwino kwambiri yamagetsi yamagetsi Teflon ndi zinthu zopanda polar zomwe zimakhala ndi dielectric zabwino, kukana kwambiri komanso kukhazikika kwa dielectric pafupifupi 2.0, yomwe ndi yaying'ono kwambiri pakati pa zida zonse zotchinjiriza magetsi, ndipo kusintha kwa kutentha ndi ma frequency sikumakhudza iwo. .

5) Kukana kukalamba kwabwino komanso kukana kwa radiation, kumatha kugwiritsidwa ntchito panja kwa nthawi yayitali.

6) Kukhazikika kwabwino kwamafuta, Teflon ili ndi incombustibility yamtengo wapatali kwambiri, index yake ya oxygen malire ili pamwamba pa 95, imatha kusungunuka pamoto, simapanga madontho, ndipo imatha kukhala carbonized.

7) Kufewa kwakukulu ndi kukana kupindika.

8) kukana chinyezi: pamwamba pa filimu ya Teflon ilibe madzi ndi mafuta, ndipo sikophweka kuti ikhale yodetsedwa ndi yankho panthawi yopanga ntchito.Ngati pali dothi laling'ono lotsatiridwa, likhoza kuchotsedwa ndi kupukuta kosavuta.Lili ndi ubwino wa nthawi yochepa yopuma, kupulumutsa ola la munthu komanso kuwongolera bwino ntchito.

9) Valani kukana: kukana kwambiri kuvala pansi pa katundu wambiri.Pansi pa katundu wina, ili ndi ubwino wa kukana kuvala komanso kusamata.

Polytetrafluoroethylene hose ili ndi zabwino zina kuposa payipi wamba wokhala ndi mphira.

Choyamba, polytetrafluoroethylene (PTFE) payipi amachita ngati nthunzi chotchinga, amene si zomata pa nthawi yomweyo kutentha kukana mkulu, ndipo akhoza kukwaniritsa zofunika za makina amenewa ndi zipangizo ntchito mipope.

Chachiwiri, PTFE ali pamzere payipi ali apamwamba kwambiri kukana mankhwala ndipo amathandiza osiyanasiyana magalimoto zamadzimadzi kuti mphira wamba sangathe kupereka, ambiri kukhala mafuta zikuphatikiza munali Mowa.Paipi ya rabara wamba imawola ikakumana ndi mtundu wotere wa petulo ndipo pamapeto pake imatsika mpaka imayamba kutsika kapena kubaya mafuta, zomwe ndi zowopsa.

Chachitatu, payipi ya Teflon imakhala ndi kutentha kwakukulu kwambiri - kwenikweni, kutentha kwa kutentha kwa payipi yogulitsidwa ndi machubu a PTFE ndi - 65 ° C mpaka + 260 ° C. Ndizoyenera kwambiri kugwiritsa ntchito zipangizozi.

Chachinayi, payipi ya Teflon chubu ya Teflon imakhala ndi kuthamanga kwambiri, ndikuwonetsetsanso kuti mutha kugwiritsa ntchito mitundu yonse yamagalimoto ndi ndodo zotentha.Kukula kwa An6 kwa 2500psi, kukula kwa an8 kwa 2000psi, ngakhale ntchito zovuta kwambiri, kupanikizika kwake ndikokwanira.

zina?Inde, kwenikweni - zolukidwa mu payipi yathu zimatsimikizira moyo wautali wautumiki komanso mawonekedwe akuthwa pakuyika.Mukasankha chitsulo chosapanga dzimbiri, chimakhala chowoneka chakuthwa ndipo chimakupatsirani katswiri wamapaipi otenthetsera ndodo.Nayiloni yakuda ngati mukufuna mawonekedwe ofewa.Koma mukudziwa, nayiloni wakuda akadali ndi chitsulo chosapanga dzimbiri.Timangofunika kuvala chitsulo chosapanga dzimbiri ndi nayiloni wakuda kuti tiwoneke mosiyana.

Tsopano ikupezeka - yabuluu ndi yofiyira Nayiloni Yolukidwa PTFE yokhala ndi payipi yotentha yamafuta amtundu wa an6.

Chifukwa chake payipi ya PTFE ikumveka bwino - chavuta ndi chiyani?

Nthawi zambiri, chubu la PTFE limatha kulowa m'malo ambiri amtundu wa rabala.Choyipa chokha cha PTFE chubu ndikuti kusinthasintha kwake sikuli bwino ngati chubu la rabara.Komabe, ma bellows angapo a PTFE chubu ali ndi kusinthasintha kwina, komwe kumatha kuthana ndi vuto laling'onoli.Koma pali zinthu zina zomwe muyenera kuzidziwa.

1 - kwa PTFE payipi payipi, muyenera kugwiritsa ntchito zovekera yoyenera kuchokera kwa wopanga yemweyo kuonetsetsa kusindikiza bwino pa zozolowera.Popeza kuti chisindikizocho chimapangidwa ndi ferrule m'malo mwa kuika pa payipi ya rabara, chisamaliro chiyenera kuchitidwa podula.Kuti mudziwe zambiri, onani malangizo athu oyika.

Kupindika kwa payipi ya 2-ptfe kumakhala kolimba kwambiri chifukwa kumakhala kosavuta kuyimba ngati kupitilira zomwe zafotokozedwa.Kuti mumve zambiri, onani nkhani yathu pa bend radius.

Sizili choncho ndi payipi yamafuta otentha, koma ngati mumagula zinthu,PTFE hosenthawi zambiri imakhala yokwera mtengo kuposa payipi yokhala ndi mphira - mtengo wa payipi yotentha yamafuta ndi yabwino kwambiri, nthawi zambiri mtengo wa payipi ya rabara, ndipo umakhala kwa nthawi yayitali.
