Kodi ptfe lined hose ndi chiyani |Malingaliro a kampani BESTEFLON

M'zaka zaposachedwa, polytetrafluoroethylene (Teflon) ndi mtundu wa anti fouling ndi anti fouling mankhwala mphamvu yamagetsi ndi makampani petrochemical.Komabe, mavuto otsatirawa ayenera kuperekedwa chisamaliro chapadera pamenePTFE ili pamzerepayipimzerewu ndi welded, apo ayi moyo wautumiki ndi chitetezo cha payipi ya PTFE idzakhudzidwa.

1. Poyeretsa msonkhano wa msonkhano, ndizoletsedwa kuwononga zitsulo zoyambira.Ndikoletsedwa kumenya arc pazitsulo zoyambira panthawi yowotcherera.

2. Mu gawo la fillet weld weld, kutalika kwa fillet weld kudzakhala kwakukulu kuposa 5mm, mbali yowonetsera idzakhala yayikulu kuposa kapena yofanana ndi 3mm, ndipo mbali yamkati idzakhala yayikulu kuposa kapena yofanana ndi 10mm.

3. Pamene kuwotcherera chipolopolo cha PTFE ali pamzere chitoliro, ndi bwino kutengera njira kuwotcherera iwiri kumbali matako kuwotcherera.Izi zimafuna luso mlingo wa antchito athu, kuwotcherera ayenera lathyathyathya (yosalala kapena yosalala kusintha), palibe pores, kuwotcherera msoko ndi slag kuphatikiza chodabwitsa, ndi kutalika kwa weld sayenera kukhala wamkulu kuposa 2mm.Pambuyo kuwotcherera, spatter yomwe imayambitsidwa ndi kuwotcherera idzachotsedwa kwathunthu.

4. kuwotcherera mosalekeza ayenera anatengera mu kuwotcherera wa PTFE alimbane chitoliro, ndi kuwotcherera msoko sadzakhala ndi ming'alu kapena mosalekeza undercut.Zosaka Zofananira:payipi ya PTFE yoluka, PTFE payipi convoluted

Polytetrafluoroethylene (PTFE) ndi amodzi mwa mayina omwe amagwiritsidwa ntchito kwambiri a polytetrafluoroethylene.PTFE payipi imagwiritsidwa ntchito muzitsulo zosapanga dzimbiri, motero moyo wautumiki wa payipi ndi wautali kwambiri kuposa payipi ya rabala kapena payipi ya rabala yokutidwa ndi chitsulo chosapanga dzimbiri.Lili ndi ubwino wambiri kuposa mankhwala a rabara.

Kalasi I: PTFE yokhala ndi mizere yowongoka ya chitoliro ndi zitoliro

Imadziwika kuti loose liner pipe.Pochita izi, PTFE imagwiritsidwa ntchito kutembenuza bar.Ndioyenera kukakamiza wamba komanso mapaipi oyendetsa bwino (monga mapaipi atatu ochotsa zinyalala, ndi zina zotero), ndipo sayenera kugwiritsidwa ntchito popanga payipi yokhala ndi katundu (monga polowera ndi potulutsa pompo ndi payipi yomwe imatha kutulutsa kupanikizika koyipa. mwa kugwa kapena kuziziritsa mwadzidzidzi).

M'mimba mwake mfundo: dn25-500mm

Kutentha kwa utumiki: - 40-180oc

Kuthamanga kwa Service: 1.6Mpa

Kalasi II: PTFE zolimba zokhala ndi mizere yowongoka ndi zitoliro

Amadziwika kuti chitoliro cholimba chokulungidwa ndi waya wachitsulo.

Kupanga ndondomeko: choyamba, zigawo zingapo za PTFE filimu anavulala pa nkhungu, ndiye chitsulo waya (Ø 0.5-1mm) ndi spiral bala pa PTFE filimu, ndiyeno zigawo zingapo za PTFE woonda filimu anavulala kunja kwa chitsulo. waya, ndipo pamapeto pake anakulungidwa mu ng'anjo kuti apange.Khoma lamkati la PTFE alimbane chitoliro chopangidwa ndi ndondomekoyi ndi yosalala, ndipo khoma lakunja ndi lopangidwa ndi corrugated chifukwa cha voliyumu ndi mphamvu zotanuka za waya wachitsulo.

Danga pakati pa khoma lakunja la PTFE alimbane chitoliro ndi mkati khoma la zitsulo chitoliro wodzazidwa ndi utomoni (popanda mpweya yotsalira).Utomoni wodzaza ukhoza kumangirizidwa mwamphamvu ku chitoliro chachitsulo.Nthawi yomweyo, imatha kukulungidwa mwamphamvu pakhoma lakunja la PTFE liner.Pambuyo pa kuchiritsa kwa utomoni wodzazidwa, phokoso lozungulira limapangidwa lomwe limatsekedwa ndi khoma lakunja lachitsulo.Kapangidwe kameneka kakufanana ndi kuphatikiza kwa mtedza ndi bawuti.Kumbali imodzi, imatha kuchepetsa ndikulipiritsa kukula kwamafuta ndi kuzizira kwa PTFE akalowa;Komano, zitsulo waya stiffness akhoza kwambiri kusintha zoipa kuthamanga kukana PTFE akalowa.

M'mimba mwake: dn25-200 mm

Ntchito kutentha: - 50-180oc

Kuthamanga kwa ntchito: 0.5-1.6mpa

Mtundu wachitatu: PTFE kukankha (finyani) chitoliro mwamphamvu alimbane ndi chitoliro molunjika

Imadziwikanso kuti kukankha (kufinya) mizere yowongoka, imagwiritsidwa ntchito kwambiri m'maiko otukuka m'ma 1990.

Njira yopanga: choyamba, PTFE ufa wotumizidwa kunja umagwiritsidwa ntchito kukankhira (extrude) chitoliro, ndiyeno amakakamizika mu chitoliro chopanda zitsulo (m'mimba mwake wakunja wa liner ndi wokulirapo pang'ono kuposa m'mimba mwake wamkati wa chitoliro chachitsulo ndi 1.5- 2mm) kuti apange mzere wosasunthika.Pofuna kuthetsa kupanikizika, amaikidwa mu ng'anjo ndikutenthedwa mpaka 180oC kuti athetse kutentha kwanthawi zonse, kuti athe kugwiritsidwa ntchito kutentha pansi pa 180oC.Pa nthawi yomweyi, kanikizani (finyani) tsinde la chitoliro

Kulimba kwamphamvu mwachiwonekere kuli bwino kuposa chubu lachilonda.Mapaipi ali ndi kukana koyenera kwa kukakamiza kwabwino komanso koyipa.

Kusiyana pakati pa PTFE lining ndi rabara

Lining tetrafluoroethylene imagwiritsidwa ntchito kukana kwa dzimbiri kwa fluorine, kukana kutentha kwambiri, kukana kwa asidi ndi alkali, kumamatira kwambiri, moyo wautali wautumiki komanso kukana kulowa mkati.The lonse kupopera mbewu mankhwalawa tetrafluoroethylene ndi ntchito chatekinoloje, kodi ndondomeko yake ikuyenda bwanji?1. Musanayambe kupopera mbewu mankhwalawa, pamwamba pake payenera kukhala mchenga ndi kuuma, ndipo wosanjikiza wa primer wapadera amapopera.2. Ndiye fuloroplastic ufa mlandu ndi mkulu-voteji electrostatic zida, ndi wogawana adsorbed pamwamba pa workpiece pansi zochita za kumunda magetsi.3. Pambuyo pophika kutentha kwakukulu, tinthu tating'onoting'ono ta clinker timasungunuka kukhala wosanjikiza wotetezera, womwe umamangirizidwa mwamphamvu pamwamba pa workpiece.Mwachitsanzo, filimu yopaka 1 mm wandiweyani iyeneranso kupopera ndikuphika mobwerezabwereza kwa 5-6.Nthawi zambiri, makulidwe apamwamba amatha kupopera mpaka 2mm.PTFE lining ndi ukadaulo wogwiritsidwa ntchito kwambiri masiku ano.Amagwiritsa ntchito mokwanira kukana kwa dzimbiri kwa fluorine, kuyera kwakukulu, ukhondo, kusamata, kusanyowetsa, kudzipaka mafuta, kukana kuvala, kukana kutentha kwambiri komanso kutsika, kusungunula, etc. malo abwino kukwaniritsa ❖ kuyanika zotsatira.Kupaka mphira kumatchedwanso mphira.Ndiko kumata mbale ya rabara yokonzedwa pamwamba pa zitsulo ndi zomatira kuti alekanitse sing'anga yowononga ndi matrix achitsulo ndi cholinga chotetezera.Labala wachilengedwe ndi mphira wopangira amagwiritsidwa ntchito poyala.Ambiri mwa mphira omwe amagwiritsidwa ntchito muzitsulo zazitsulo ndi mphira wachilengedwe.Chigawo chachikulu cha mphira wachilengedwe ndi cis polymer ya isoprene, yomwe imatenthedwa powonjezera sulfure.The vulcanized labala ali ndi kutentha kukana ndi mphamvu makina.Ikhoza kugawidwa mu mphira wofewa, mphira wovuta kwambiri ndi mphira wolimba mitundu itatu.Rabara yolimba imakhala ndi kukana kwa dzimbiri, kukana kukalamba komanso kulimba kolumikizana ndi chitsulo.Rabara yofewa imakhala ndi kukana kuzizira bwino, kukana kutentha ndi kukana kukhudzidwa, ndipo imakhala ndi mphamvu zina;mphira wa semi hard ndi pakati pa awiri.Kuphatikiza pa ma oxidants amphamvu ndi zosungunulira zina, mphira wolimba umatha kukana dzimbiri la ma acid ambiri, ma organic acid, alkali, mchere ndi mowa.Chifukwa chake, mphira wolimba umagwiritsidwa ntchito ngati chinthu chachikulu chosagwirizana ndi chitsulo.mphira Vulcanized akhoza kugawidwa mu chisanadze vulcanized mphira, yachibadwa kuthamanga madzi otentha vulcanized mphira ndi zachilengedwe vulcanized mphira.Labala yopangidwa ndi prevulcanized imagwiritsidwa ntchito pazida zazikulu zonyamula.
