Kodi payipi ya ptfe ndi chiyani | BESTEFLON

Kodi mwamvapo za zinthu za PTFE ndipayipi ya PTFETiyeni tiwone ngati tingayankhe mafunso ena okhudza nkhaniyi.

Polytetrafluoroethylene (polytetrafluoroethylene) ndi chidule cha PTFE, chomwe chimadziwika kuti "mfumu ya pulasitiki", ndipo dzina lake lamalonda ndi Teflon. Ku China, chifukwa cha katchulidwe kake, "TEFLON" imadziwikanso kuti Teflon, zonse zomwe ndi Teflon. Polytetrafluoroethylene imadziwikanso kuti "mfumu ya pulasitiki", bambo wa kampani ya fluororesin Roy Planck 1936 DuPont ku United States anayamba kuphunzira za zinthu zolowa m'malo mwa Freon. Anasonkhanitsa tetrafluoroethylene ndikuzisunga m'masilinda kuti akayesere tsiku lotsatira. Komabe, pamene valavu yochepetsera kuthamanga kwa silinda inatsegulidwa tsiku lotsatira, palibe mpweya wodzaza. Anaganiza kuti ndi kutuluka kwa madzi, koma atayeza silinda, adapeza kuti silindayo sinachepetse kulemera. Anayang'ana silindayo ndipo adapeza ufa woyera wambiri, womwe ndi polytetrafluoroethylene. Anapeza kuti polytetrafluoroethylene ili ndi mphamvu zabwino kwambiri ndipo ingagwiritsidwe ntchito ngati gasket yoteteza kusungunuka kwa mabomba a atomiki ndi zipolopolo. Chifukwa chake, asilikali aku US adasunga ukadaulowu chinsinsi panthawi ya Nkhondo Yachiwiri Yapadziko Lonse. Sizinali mpaka kumapeto kwa Nkhondo Yachiwiri Yapadziko Lonse pomwe idachotsedwa m'gulu la mafakitale ndikukhala ndi mafakitale mu 1946. Zofufuza Zofanana:Paipi yolumikizidwa ndi PTFE, payipi ya PTFE yozungulira

Polytetrafluoroethylene imatha kupangidwa mwa kukanikiza kapena kutulutsa; imathanso kupangidwa kukhala madzi ofalikira kuti iphimbe, impregnation kapena ulusi. Polytetrafluoroethylene (PTFE) imagwiritsidwa ntchito kwambiri m'mafakitale a mphamvu ya atomiki, chitetezo cha dziko, ndege, zamagetsi, zamagetsi, zamagetsi, uinjiniya wa mankhwala, makina, zida, zida, zomangamanga, nsalu, chithandizo cha pamwamba pa zitsulo, mankhwala, zamankhwala, nsalu, chakudya, zitsulo ndi mafakitale osungunula, ndi zina zotero, zomwe zimapangitsa kuti ikhale chinthu chosasinthika.

PTFE ndi chidule cha polytetrafluoroethylene - ndi mawu ataliatali, koma long ayenera kutanthauza kuti ndi labwino! Dzina la chizindikiro cha polytetrafluoroethylene ndi dzina lodziwika bwino 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 cha makina oziziritsira madzi ndi chitoliro cha mabuleki?

1) Chubu cha PTFE chili ndi kukhazikika kwa mankhwala ndipo chimatha kupirira mphamvu zonse za asidi amphamvu, kuphatikizapo aqua regia, hydrofluoric acid, concentrated hydrochloric acid, nitric acid, fuming sulfuric acid, organic acid, strong base, strong oxidant, reducing agent ndi zinthu zosiyanasiyana zachilengedwe. Chimagwiritsidwa ntchito kwambiri popereka madzi amphamvu osiyanasiyana.

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

3) Kusakhuthala bwino komanso kukana kukhuthala ndi kwabwino kwambiri, ndipo khoma lamkati la chitoliro siligwirizana ndi ma colloid ndi mankhwala, kotero silipanga dothi mu chitolirocho.

4) Kugwira ntchito bwino kwambiri poteteza magetsi Teflon ndi chinthu chosakhala cha polar chomwe chili ndi mphamvu zabwino za dielectric, cholimba kwambiri komanso chosasinthasintha cha dielectric cha pafupifupi 2.0, chomwe ndi chaching'ono kwambiri pakati pa zipangizo zonse zoteteza magetsi, ndipo kusintha kwa kutentha ndi ma frequency sikukhudza kwambiri.

5) Kukana ukalamba bwino komanso kukana kuwala kwa dzuwa, kungagwiritsidwe ntchito panja kwa nthawi yayitali.

6) Kukhazikika kwa kutentha kwabwino kwambiri, Teflon ili ndi mphamvu yosayaka kwambiri, index yake ya mpweya wokwanira ndi yoposa 95, imatha kusungunuka mu moto wokha, siimatulutsa madontho, ndipo imatha kusinthidwa kukhala kaboni.

7) Kufewa kwambiri komanso kukana kupindika.

8) Kukana chinyezi: pamwamba pa filimu ya Teflon palibe madzi ndi mafuta, ndipo sikophweka kupakidwa utoto ndi yankho panthawi yopangira. Ngati pali dothi laling'ono lomwe lamatiridwa, likhoza kuchotsedwa pongopukuta mosavuta. Lili ndi ubwino wokhala ndi nthawi yochepa yopuma, kusunga maola ogwira ntchito komanso kukonza magwiridwe antchito.

9) Kukana kuvala: kukana kuvala bwino kwambiri mukanyamula katundu wambiri. Mukanyamula katundu winawake, ili ndi ubwino wokana kuvala komanso kusagwira ntchito.

Paipi ya polytetrafluoroethylene ili ndi ubwino wina kuposa paipi wamba wokhala ndi rabara.

Choyamba, payipi ya polytetrafluoroethylene (PTFE) imagwira ntchito ngati chotchinga nthunzi, chomwe sichimamatira panthawi yomweyi chifukwa cha kutentha kwambiri, ndipo imatha kukwaniritsa zofunikira za makina ndi zida izi kuti igwiritse ntchito mapaipi.

Chachiwiri, payipi ya PTFE yokhala ndi mankhwala oletsa kwambiri mankhwala ndipo imathandizira mitundu yosiyanasiyana yamadzimadzi agalimoto omwe mphira wamba sungapereke, omwe nthawi zambiri amakhala mafuta osakaniza okhala ndi ethanol. Paipi wamba ya rabara imawola ikakumana ndi mafuta amtunduwu ndipo pamapeto pake imawonongeka mpaka kufika poti ingayambe kutuluka kapena kulowetsa mafuta, zomwe ndi zoopsa kwambiri.

Chachitatu, payipi yolumikizidwa ndi Teflon ili ndi kukana kutentha kwambiri - kwenikweni, kutentha komwe payipi yogulitsidwa ndi machubu a PTFE imagwiritsa ntchito ndi - 65°C mpaka + 260°C. Ndi yoyenera kwambiri kugwiritsidwa ntchito pazida izi.

Chachinayi, chubu cha Teflon payipi ya Teflon ili ndi kuthamanga kwambiri kwa ntchito, zomwe zimatsimikiziranso kuti mutha kuigwiritsa ntchito pamitundu yonse ya magalimoto ndi ma hot rod. Kukula kwa An6 kwa 2500psi, kukula kwa an8 kwa 2000psi, ngakhale ntchito zovuta kwambiri, kuthamanga kwake ndikokwanira.

china? Inde, kwenikweni - cholukidwa mu payipi yathu chimatsimikizira kuti chimagwira ntchito nthawi yayitali komanso chimawoneka bwino kwambiri poyika. Mukasankha chitsulo chosapanga dzimbiri, chimakhala ndi mawonekedwe akuthwa ndipo chimakupatsani mawonekedwe a hot rod aukadaulo waukadaulo. Nayiloni wakuda ngati mukufuna mawonekedwe ofewa. Koma mukudziwa, nayiloni wakuda akadali ndi mkati mwa chitsulo chosapanga dzimbiri. Timangofunika kupaka chitsulo chosapanga dzimbiri ndi nayiloni wakuda kuti tipeze mawonekedwe osiyana.

Tsopano ikupezeka - payipi yabuluu ndi yofiira ya Nayiloni yoluka ya PTFE yokhala ndi payipi yamafuta ya hot rod kukula kwa payipi ya an6.

Kotero payipi ya PTFE ikumveka bwino - vuto lake ndi chiyani?

Kawirikawiri, chubu cha PTFE chingalowe m'malo mwa zinthu zambiri za chubu cha rabara. Vuto lokhalo la chubu cha PTFE ndilakuti kusinthasintha kwake sikwabwino ngati kwa chubu cha rabara. Komabe, chubu cha PTFE chokhala ndi bellows chili ndi kusinthasintha kwina, komwe kumatha kuthetsa vuto laling'onoli. Koma pali zinthu zina zomwe muyenera kudziwa.

1 - pa payipi yolumikizidwa ndi PTFE, muyenera kugwiritsa ntchito zolumikizira zoyenera kuchokera kwa wopanga yemweyo kuti muwonetsetse kuti zolumikizirazo zatsekedwa bwino. Popeza chosindikiziracho chimapangidwa ndi ferrule m'malo mwa choyikapo pa payipi ya rabara, muyenera kusamala kwambiri podula. Kuti mudziwe zambiri, onani malangizo athu oyika.

Utali wopindika wa payipi ya 2-ptfe ndi wokhwima kwambiri chifukwa udzakhala wosavuta kuukanda ngati upitirira muyezo. Kuti mudziwe zambiri, onani nkhani yathu yokhudza utali wopindika.

Sizili choncho ndi payipi yamafuta otentha, koma ngati mukuyang'ana malo osiyanasiyana,payipi ya PTFEnthawi zambiri zimakhala zodula kuposa payipi yokhala ndi rabara - mtengo wa payipi yamafuta otentha ndi wabwino kwambiri, nthawi zambiri mtengo wake ndi wokwera kangapo kuposa payipi ya rabara, ndipo udzakhalapo kwa nthawi yayitali.
