Makhalidwe aPTFE makina omangira.
1. Teflon automatic akamaumba makina/ tetrafluoro akamaumba makina, ntchito wanzeru, 24 maola mosalekeza kupanga chingapezeke.
2. Kuyika pawokha, kutentha kwa mafuta, zinthu, kuyang'anira nthawi yeniyeni yogwira ntchito ya dipatimenti iliyonse ya zipangizo, ntchito yoyang'anira kutali ikupezeka, ndipo mbale ya makina a mkono imayikidwa bwino.
3. Ikhoza kupanga basi bar, chitoliro, zigawo zooneka bwino, zokhala ndi mitundu yosiyanasiyana ya nkhungu, makina amodzi okhala ndi nkhungu zambiri ndi magawo angapo, chitolirocho chikhoza kukwaniritsa makulidwe a khoma la 2mm.cholakwika cha kutalika kwa magawo opangidwa amatha kuwongoleredwa pa ± 0.02mm.
Chiyambi cha malonda.
Polytetrafluoroethylene imadziwika kuti tetrafluoro, Teflon, King Plastic, Teflon, ndipo makina opangira ndi makina apadera opangira zinthu za polytetrafluoroethylene.Zopangira za PTFE ufa zimawumbidwa, zimatenthedwa ndi kuziziritsa kudzera m'magawo angapo opangidwa ndi zida kuti apange zinthu zopangidwa molingana ndi mawonekedwe osiyanasiyana.Kutengera kugwiritsa ntchito, mawonekedwe, zosakaniza, zosowa za ogwiritsa ntchito ndi zinthu zina zofananira, mawonekedwe osiyanasiyana a makina omangira amatha kupangidwa ndikupangidwa.Zogulitsa za PTFE zomwe zimapangidwa zimagwiritsidwa ntchito kwambiri mumankhwala, zakuthambo, zida zamakina, kusinthanitsa kutentha ndi zina.
The ptfe akamaumba ndondomeko
Njira yopangira ptfe ndiyo njira yomwe imagwiritsidwa ntchito kwambiri.PTFE akamaumba angagwiritsidwe ntchito pokonza mbale, ndodo, manja, matepi, mphete zomata, diaphragms, ndi mbali zoikamo zitsulo.
The ptfe akamaumba njira kwenikweni imakhala ndi masitepe anayi: kusakaniza, preforming, sintering, ndi kuzirala.Preforming ndi ndondomeko yowonjezera ptfe ufa mofanana mu nkhungu ndikukankhira mu preform wandiweyani (ie, opanda kanthu) kutentha;sintering ndi njira yowotchera preform pamwamba pa malo osungunuka ndipo kuziziritsa ndi njira yochepetsera kutentha kwa sintering kutentha.
Ena ptfe mbamuikha mwakamodzi pamwamba kusungunuka kutentha, nkhungu akamaumba, amatchedwa otentha kukanikiza nkhungu, ndi lolingana PTFE nkhungu amatchedwa ozizira kukanikiza nkhungu.
Pamene ptfe akamaumba ayenera kulabadira psinjika chiŵerengero (a Yin PTFE kwa 4-6) ndi akamaumba shrinkage (nthawi zambiri PTFE kwa 2.6-4.5%) pa zotsatira za mankhwala.
Zabwino zopangira ndi kuyimitsidwa polymerization utomoni, tinthu kukula 20-500 microns wa lotayirira ufa wabwino kwambiri.Kukanikiza ndondomeko kuyenera kukhala "deflated", pre-forming pressure of 17-35 MPa, akugwira nthawi malinga ndi makulidwe akusowekapo, monga 100 mm wandiweyani akusowekapo, ayenera kukakamiza kwa mphindi 15.
