Chii chinonzi ptfe hose | BESTEFLON

Wakambonzwa here nezvezvinhu zvePTFE uyeHosipa yePTFENgationei kana tichigona kupindura mimwe mibvunzo nezvazvo.

Polytetrafluoroethylene (polytetrafluoroethylene) inopfupikiswa sePTFE, inowanzozivikanwa se "plastic king", uye zita rayo rekutengeserana ndiTeflon. MuChina, nekuda kwemataurirwo ayo, "TEFLON" inozivikanwawo seTeflon, iyo yose inoshandurwa kubva kuTeflon. Polytetrafluoroethylene inozivikanwa se "mambo wepurasitiki", baba vekambani yefluororesin Roy Planck 1936 DuPont muUnited States vakatanga kudzidza nezvezvinotsiva Freon. Vakaunganidza tetrafluoroethylene ndokuichengeta mumasilinda kuti vaedze zuva rinotevera. Zvisinei, apo vharuvhu yekumanikidza yesilinda yakavhurwa zuva rakatevera, hapana gasi rakazadzwa. Vakafunga kuti kwaive kudonha, asi pavakayera silinda, vakaona kuti silinda haina kudzikira huremu. Vakaona kuburikidza nesirinda ndokuwana hupfu hwakawanda hwechena, hunova polytetrafluoroethylene. Vakaona kuti polytetrafluoroethylene ine hunhu hwakanaka uye inogona kushandiswa segasket rekudzivirira kunyunguduka kwemabhomba eatomu nemagoko. Saka, mauto eUS akachengetedza tekinoroji iyi chakavanzika panguva yeHondo Yenyika II. Zvakatozobviswa muzvikamu zvebhizinesi uye zvakawedzerwa maindasitiri muna 1946 kusvika pakupera kweHondo Yenyika II.Hosipaipi yePTFE yakarukwa, Hosipaipi yePTFE yakakombama

Polytetrafluoroethylene inogona kugadzirwa nekudzvanywa kana kubudiswa; inogonawo kugadzirwa kuita kupararira kwemvura kuti ifukidzwe, impregnation kana fiber. Polytetrafluoroethylene (PTFE) inoshandiswa zvakanyanya mumaindasitiri esimba reatomu, dziviriro yenyika, ndege, zvemagetsi, zvemagetsi, zveinjiniya yemakemikari, michina, zvemidziyo, zvekushandisa, zvekuvaka, zvemachira, zvekurapa pamusoro pesimbi, zvemishonga, zvekurapa, zvemachira, zvekudya, zvesimbi uye zvekugadzira simbi, nezvimwewo, izvo zvinoita kuti ive chigadzirwa chisingatsiviwi.

PTFE ipfupiso ye polytetrafluoroethylene - izwi refu, asi refu rinofanira kureva kuti rakanaka! Zita rechiratidzo che polytetrafluoroethylene ndiro zita rinonyanya kuzivikanwa re polytetrafluoroethylene.

Sei pombi ye polytetrafluoroethylene (PTFE) ichishandiswa mu inkjet pombi ye 3D printer, pombi yekudyisa kofi muchina, pombi yekutonhodza mvura uye pombi yebhureki?

1) PTFE chubhu ine kugadzikana kwakanyanya kwemakemikari uye inogona kutsungirira kushanda kwemaacid ese akasimba, kusanganisira aqua regia, hydrofluoric acid, concentrated hydrochloric acid, nitric acid, fuming sulfuric acid, organic acid, strong base, strong oxidant, reducing agent uye organic solvents dzakasiyana-siyana. Inoshandiswa zvakanyanya mukutakura mvura dzakasiyana-siyana dzakaoma.

2) Inogona kushandiswa kwenguva yakareba pakati pe -80 ℃ - + 280 ℃. Inogona kushanda pakupisa kwechando isina kupwanyika kana kunyunguduka pakupisa kwakanyanya.

3) Kusanyanya kusimba uye kusasimba kwakanyanya, uye rusvingo rwemukati rwepombi harunamatire kune macolloid nemakemikoro, saka haruzove nevhu mupombi.

4) Kushanda zvakanaka kwazvo pakuputira magetsi Teflon chinhu chisina polar chine hunhu hwakanaka hwe dielectric, resistance yakanyanya uye dielectric constant inosvika 2.0, inova diki pane zvese zvemagetsi zvinoputira magetsi, uye kuchinja kwetembiricha uye frequency hakuna zvakunoita pazviri.

5) Inodzivirira kukwegura zvakanaka uye inodzivirira mwaranzi, inogona kushandiswa panze kwenguva yakareba.

6) Kugadzikana kwakanyanya pakupisa, Teflon ine simba risingatsve, chiyero chayo cheoxygen limit chiri pamusoro pe95, inogona kunyunguduka chete mumoto, haiburitse madonhwe, uye inogona kungoiswa carbon dioxide chete.

7) Kupfava kwakanyanya uye kuramba kukotama.

8) Kudzivirira hunyoro: pamusoro pefirimu reTeflon hapana mvura nemafuta, uye hazvisi nyore kusvibiswa nemushonga panguva yekugadzira. Kana paine tsvina shoma yakanamatira, inogona kubviswa nekupukuta zviri nyore. Ine zvakanakira zvekushanda kwenguva pfupi, kuchengetedza nguva yekushanda uye kuvandudza kushanda zvakanaka.

9) Kudzivirira kupfeka: Kudzivirira kupfeka kwakanaka kana paine mutoro wakawanda. Kana paine mutoro wakati, ine zvakanakira zvekusapfeka uye kusanamatira.

Hosipaipi yepolytetrafluoroethylene ine zvayakanakira pane hosipaipi yakajairwa yakagadzirwa nerabha.

Chekutanga, pombi yepolytetrafluoroethylene (PTFE) inoshanda sechidziviriro cheutsi, chisinganamire panguva imwe chete chinodzivirira kupisa kwakanyanya, uye inogona kusangana nezvinodiwa nemichina iyi nemidziyo yekushandisa mapaipi.

Chechipiri, hosipaipi yePTFE ine simba guru rekudzivirira makemikari uye inotsigira mvura dzakasiyana-siyana dzemotokari dzisingagone kupihwa nerabha, dzinowanzo shandiswa nemafuta ane ethanol. Hosipaipi yerabha inoora kana yaiswa mumhando iyi yepeturu uye inozopedzisira yaora zvekuti inogona kutanga kudonhedza mvura kana kuisa mafuta, izvo zvine njodzi huru.

Chechitatu, hosipaipi yeTeflon ine simba rekudzivirira kupisa kwakanyanya - kutaura zvazviri, tembiricha inoshandiswa yehosipaipi inotengeswa nemachubhu ePTFE ndeye - 65° C kusvika + 260° C. Yakakodzera kushandiswa pamidziyo iyi.

Chechina, chubhu yeTeflon Hosipu yeTeflon ine simba rekushanda rakanyanya, zvakare ichivimbisa kuti unogona kuishandisa kune ese marudzi ekushandisa mota uye hot rod. Saizi yeAn6 ye2500psi, saizi yean8 ye2000psi, kunyangwe mashandisirwo akanyanya kuoma, simba rayo rinokwana.

zvimwe? Ehe, kutaura chokwadi - simbi yakarukwa mupaipi yedu inoita kuti igare kwenguva refu uye ive nechitarisiko chakajeka chekuisa. Paunosarudza simbi isingatsvedzeri, ine chitarisiko chakajeka uye inoita kuti inzwe seyenyanzvi yekugadzira mapaipi. Nylon nhema kana uchida chitarisiko chakapfava. Asi unoziva, nylon nhema ichiri nejira resimbi isingatsvedzeri. Tinongoda kuputira simbi isingatsvedzeri nenylon nhema kuti iwane chitarisiko chakasiyana.

Iye zvino yava kuwanikwa - bhuruu netsvuku, nylon braided PTFE lined hose, hot rod fuel hose ine saizi an6.

Saka PTFE hose inonzwika zvakanaka - chii chiri kunetsa nayo?

Kazhinji, chubhu yePTFE inogona kutsiva akawanda emamiriro ezvinhu erubhu. Dambudziko rega rePTFE chubhu nderekuti kuchinjika kwayo hakuna kunaka sekwerubhu yerabha. Zvisinei, PTFE chubhu ine bellows series ine kuchinjika kwakati, izvo zvinogona kugadzirisa dambudziko iri diki. Asi pane zvimwe zvinhu zvaunofanira kuziva.

1 - pahosipaipi yakagadzirwa nePTFE, unofanirwa kushandisa zvigadziko zvakakodzera kubva kumugadziri mumwe chete kuti uve nechokwadi chekuti zvigadziko zvacho zvakavharwa zvakanaka. Sezvo chigadziko chacho chakagadzirwa neferrule pachinzvimbo chekuisa pahosipaipi yerabha, kungwarira kwakawanda kunofanira kuitwa pakucheka. Kuti uwane rumwe ruzivo, ona mirairo yedu yekuisa.

Radius yekukombama yehosipu ye2-ptfe yakanyanya kuoma nekuti zvichava nyore kuikwenya kana ikadarika zvinodiwa. Kuti uwane rumwe ruzivo, ona chinyorwa chedu pamusoro peradius yekukombama.

Hazvina kudaro nehose yemafuta inodziya, asi kana ukatsvaga-tsvaga,Hosipa yePTFEKazhinji inodhura kupfuura hosipaipi yerabha - mutengo wehosipaipi yemafuta inodziya zvakanaka, kazhinji mutengo wayo wakapetwa kakawanda kupfuura hosipaipi yerabha, uye inogara kwenguva refu.
