Kapangidwe ka PTFE makamaka kumaphatikizapo njira zinayi zazikuluzikulu izi:
1. kaphatikizidwe ka monomer
PTFEndi polymerization wa tetrafluoroethylene (TFE) monomer polymerization wa polima mankhwala.monomer synthesis ya TFE ndiye sitepe yoyamba yopanga PTFE.Pakali pano, makampani makamaka amagwiritsa electrolytic fluorination njira kukonzekera TFE monoma, mwachitsanzo, anhydrous haidrojeni fluoride ndi ethylene pansi zinthu zina electrolysis anachita kupanga TFE monoma.
2.Polymerization reaction
TFE monoma pa kutentha ndi kuthamanga, kuwonjezera chothandizira ndi zosungunulira, polymerization anachita.Pa polymerization anachita, TFE monoma ndi mosalekeza polymerized kupanga mkulu maselo kulemera PTFE, kutentha, kuthamanga, chothandizira mtundu ndi ndende ya polymerization anachita ndi zinthu zina zidzakhudza maselo kulemera, kapangidwe ndi katundu wa PTFE.
3.Pambuyo pa chithandizo
Pambuyo polymerization anachita anamaliza, pambuyo mankhwala chofunika kupeza koyera PTFE mankhwala.Pambuyo pa chithandizo makamaka kumaphatikizapo kutsuka, kuyanika, kuphwanya, sieving ndi masitepe ena kuchotsa catalysts, solvents ndi zonyansa zina kuti atenge koyera PTFE utomoni particles.
4.Kuumba njira
PTFE utomoni particles amawumbidwa pansi zinthu zina kupeza zofunikaPZinthu za TFE.Kuumba njira monga extrusion, jekeseni akamaumba, calendering ndi zina zotero, malinga ndi zofunika zosiyanasiyana za mankhwala kusankha njira akamaumba yoyenera.Kuumba ndondomeko kutentha, kuthamanga, processing liwiro ndi zinthu zina zidzakhudza ntchito ndi khalidwe la mankhwala PTFE.
Zopangira za PTFE
Polytetrafluoroethylene (PTFE) utomoni anapeza mwangozi ndi American asayansi mu labotale mu 1936, ndipo tsopano dziko akhoza kutulutsa PTFE m'mayiko osachepera 20, ambiri mwa mayiko otukuka.China m'zaka za m'ma 60 kuti adziwe luso lopanga kupanga ndikuzindikira kupanga, wakhala wogula wamkulu wa PTFE, momwe zinthu zotsika mtengo zakhala zochulukirapo kuposa zomwe zimafunidwa, koma zinthu zambiri zapamwamba zimafunikirabe kudalira katundu wochokera kumayiko otukuka. .
Zopangira zamakono za PTFE zaku China zimatumizidwa makamaka kuchokera ku United States, Japan, ndi mayiko a ku Ulaya.Chifukwa cha mayendedwe mtengo ndi kaperekedwe kaperekedwe, China kuitanitsa Japan wamba, ndi ku Japan katundu PTFE wabwino kuti akwaniritse zofuna zapakhomo mkulu-mapeto.
Malinga ndi ndemanga yamakasitomala omaliza, zinthu zomwe zili mu mphamvu yamakina zomwe zikugwiritsidwa ntchito pazochitika zogwirira ntchito, kukana kukwawa komanso kukhazikika kwa kutentha komanso kutsika kwa kutentha, zida zotumizidwa kunja ndi zabwino kuposa zida zapakhomo.
Kugula machubu olondola a PTFE sikuti amangosankha mitundu yosiyanasiyana yamapulogalamu osiyanasiyana.Zambiri kusankha wopanga wodalirika.Besteflon Fluorine plastic Industry Co., Ltd. imakhazikika pakupanga mapaipi apamwamba a PTFE ndi machubu kwa zaka 20.Ngati muli ndi mafunso ndi zosowa, chonde omasuka kutifunsani kuti mudziwe zambiri zamaluso.
