PTFE mtundu filimu ndi mtundu watsopano wa c-kalasi kutchinjiriza zakuthupi ndi ntchito kwambiri mabuku, amene ali oyenera zofunika zapadera, monga zida zamagetsi chizindikiro ndi mtundu kapena waya kutchinjiriza, etc. Ndi zofunika ndi zofunika chuma makampani wailesi, ndege. mafakitale ndi otsogola sayansi yamagetsi ndi ukadaulo.
PTFE mtundu filimundi mtundu watsopano wa c-grade kutchinjiriza zakuthupi ndi ntchito kwambiri mabuku, amene ali oyenera zofunika zapadera, monga zida zamagetsi chizindikiro ndi mtundu kapena waya kutchinjiriza, etc. Ndi zofunika ndi zofunika chuma makampani wailesi, makampani ndege ndi kudula. -Edge electronic science and technology.Kumayambiriro kwa ntchito ya PTFE pulasitiki insulated waya ndi chingwe, izo zinali kokha kwa mawaya amkati ndi mawaya otsogolera a zipangizo zamagetsi ndi zamagetsi m'dera la kutentha kwa ndege, zombo ndi zipinda zina za injini m'munda wa asilikali.Ndi Kukwezeleza luso kukonzekera, PTFE wakhala pang'onopang'ono anawonjezera kuti boma magetsi ndi zipangizo zamagetsi mizere unsembe zambiri mkulu-kutentha chilengedwe.M'mbuyomu, zoweta PTFE mafilimu anali ambiri mitundu zachilengedwe zipangizo (chifukwa mafilimu PTFE si zophweka kuti achikuda).Kuti tisiyanitse mizere yolowera ndi yotuluka ya ma siginecha osiyanasiyana opatsirana ndikupangitsa kuti ikhale yosavuta kuzindikirika, njira yokutira idayenera kugwiritsidwa ntchito popaka utoto.
Kupanga kwamakanema amtundu wa PTFE akufikira pamlingo wina, kudzera mukuwongolera njira, mayendedwe azinthu zomwe zimapangidwa nthawi zambiri zimafika pamlingo wazinthu zakunja zofanana.Komabe, pakali pano zoweta PTFE mtundu filimu mankhwala ndi zofooka zoonekeratu mu mtundu wa mtundu ndi mbali zina za maonekedwe, monga kugawa m'njira zosiyanasiyana mawanga mtundu ndi mavuto ena.Ndi chitukuko cha teknoloji yatsopano yokonzekera mafilimu amtundu wa PTFE ndi kupititsa patsogolo kopitilira muyeso kwa osuta 'lawi retardant amafuna mawaya ndi zingwe, PTFE mtundu film mawaya insulated mawaya ndi zingwe akhala akugwiritsidwa ntchito mochulukira mokulira mu nyumba okwera, magalimoto, kompyuta. maukonde amderali, njira zapansi panthaka ndi malo ena osatentha kwambiri.
Njira yopanga filimu yamtundu wa polytetrafluoroethylene:
(1) pretreatment wa PTFE utomoni zopangira
PTFE inaimitsidwa utomoni zabwino anaikidwa wowonjezera kutentha pa 20 ℃ ~ 23 ℃ kwa maola 24 kwa pretreatment.
(2) kupangira ma inki
Ikani inorganic pigment mu mbale yowumitsa ya 2O ℃ ~ 23 ℃ kwa maola opitilira 24 kuti mugwiritse ntchito.
(3) mtundu
Mulingo wina wa pre-ankachitira PTFE inaimitsidwa utomoni utomoni zabwino anawonjezedwa kwa rammer, ndi kuchuluka kwa chisanadze ankachitira mankhwala inorganic pigment anawonjezera kusakaniza pa liwiro lalikulu kumwazikana pigment wogawana, ndi utomoni anali lotayirira kuti atsogolere akamaumba ndondomeko. .
(4) nkhungu
Zida zabwino zamtundu wa PTFE zopaka utoto zidawonjezedwa mu nkhungu ndikukanikizira kozizira, ndipo utomoni wamtundu wa 40 000g PTFE unakanikizidwa pachopanda kanthu pamakina okakamiza a matani 100 pa 2O MPa kuumba kukakamiza kumodzi.Panthawi ya kukanikiza, chidwi chinaperekedwa kutulutsa mpweya kuti zisawonongeke zazinthu zopanda kanthu.
(5) kuyimba
Kupondereza mtundu wabwino mluza wa kutentha kutentha sintering ng'anjo, Kutentha pa mlingo wa 5 ℃ / ho kuti 330 ℃, kuteteza kutentha, 3 h, ndiye kukwera pa mlingo wa 25 ℃ / h pafupifupi 380 ℃, kutchinjiriza 10 ~ 14 h, ndiyeno kuzirala pa mlingo wa 20 ~ 25 ℃ / h kuti 320 ℃, kutentha kuteteza 3 ~ 4 h, kuzirala komaliza pa mlingo wa pafupifupi 5 ℃ o/h kuti 15 ℃, o kutseka magetsi zachilengedwe. kuzirala kwa kutentha kwa chipinda, kunja kwa zinthu zamtundu.
(6) kusandutsa filimu
Ma preforms a sintered azinthu zamitundu amasinthidwa kukhala ma preforms opyapyala ndi lathe yapadera.Nembanemba yopanda kanthu ndi 0.1 mm × 100 mm × wamkulu kuposa 300 m (kukhuthala × m'lifupi × kutalika).
(7) kutsata kalendala
The mtundu malangizo akusowekapo pambuyo kutembenuka ndi kukonzedwa ndi otentha mpukutu malangizo calender (onani MKULU. 3) ndipo amakhala Directional digiri ya 1.5 ~ 1.8, makulidwe 0.05 mm theka-mbali filimu, otentha mpukutu kulamulira kutentha pafupifupi 100 ℃.
(8) kuchepetsa
Tiyeni tipange makulidwe a 0.05 mm theka-directional mtundu filimu yokhala ndi makina apadera odulira mu filimu yamtundu wa 0.PTFE yokhala ndi 05 mm×90 mm× wamkulu kuposa 10m(kukhuthala × m'lifupi × kutalika).
(9) kuyendera ma CD
Kanema wamtundu wa PTFE wokonzedwa adzayesedwa kuti awonedwe kachitidwe ka mkati, ndipo kuyang'anira mawonekedwe ndi kukula kwa filimuyo kudzachitika nthawi yomweyo.Zogulitsa zoyenerera zidzaikidwa m'matumba amafilimu a PVC okhala ndi satifiketi yoyendera.
