Njira yopangira PTFE imaphatikizapo magawo anayi akuluakulu otsatirawa:
1. kupanga monomer
PTFEndi polymerization ya tetrafluoroethylene (TFE) monomer polymerization ya ma polymer compounds. Kupanga kwa monomer kwa TFE ndi gawo loyamba pakupanga PTFE. Pakadali pano, makampaniwa amagwiritsa ntchito njira ya electrolytic fluorination kukonzekera TFE monomer, mwachitsanzo, anhydrous hydrogen fluoride ndi ethylene pansi pa mikhalidwe ina kuti electrolysis reaction ipange TFE monomer.
2. Kuyankha kwa polymerization
TFE monomer pa kutentha ndi kupanikizika kwina, imawonjezera chothandizira ndi zosungunulira, polymerization reaction. Pa nthawi ya polymerization reaction, TFE monomer imapangidwa polymer mosalekeza kuti ipange PTFE yolemera kwambiri ya molekyulu, kutentha, kupanikizika, mtundu wa chothandizira ndi kuchuluka kwa polymerization reaction ndi zinthu zina zimakhudza kulemera kwa molekyulu, kapangidwe ndi katundu wa PTFE.
3. Pambuyo pa chithandizo
Pambuyo poti njira yopangira polymerization yatha, chithandizo chikufunika kuti mupeze zinthu za PTFE zoyera. Chithandizo chikatha chimaphatikizapo kutsuka, kuumitsa, kuphwanya, kutsekereza ndi njira zina zochotsera zinthu zoyambitsa, zosungunulira ndi zonyansa zina kuti mupeze tinthu ta PTFE toyera.
4. Njira yopangira zinthu
Tinthu ta PTFE tomwe timapangidwa timapangidwa pansi pa mikhalidwe ina kuti tipeze zofunikiraPZogulitsa za TFENjira zopangira utomoni zimaphatikizapo kutulutsa, kuyika jekeseni, kuyika kalendala ndi zina zotero, malinga ndi zofunikira zosiyanasiyana za zinthuzo kuti asankhe njira yoyenera yopangira utomoni. Kutentha kwa njira yopangira utomoni, kuthamanga, liwiro la kukonza ndi zina zidzakhudza magwiridwe antchito ndi mtundu wa zinthu za PTFE.
Zipangizo zopangira za PTFE
Utomoni wa Polytetrafluoroethylene (PTFE) unapezeka mwangozi ndi asayansi aku America mu labotale mu 1936, ndipo tsopano dziko lapansi likhoza kupanga PTFE m'maiko osakwana 20, ambiri mwa iwo ndi mayiko otukuka. China m'zaka za m'ma 60 kuti iphunzire ukadaulo wopanga ndikuzindikira kupanga, yakhala yogula kwambiri PTFE, momwe zinthu zotsika mtengo zakhala zikufunidwa kwambiri, koma zinthu zambiri zapamwamba zikufunikabe kudalira zinthu zochokera kumayiko otukuka.
Zipangizo ndi zinthu za PTFE zomwe zilipo ku China zimatumizidwa kuchokera ku United States, Japan, ndi mayiko aku Europe. Chifukwa cha mtengo woyendera komanso nthawi yoperekera, China yatumiza zinthu zodziwika bwino ku Japan, ndipo Japan yatumiza zinthu za PTFE zabwino kwambiri kuti ikwaniritse zosowa zapakhomo zamtengo wapatali.
Malinga ndi ndemanga za makasitomala omaliza, zinthu zomwe zili ndi mphamvu ya makina yogwiritsira ntchito mikhalidwe yogwirira ntchito, kukana kugwedezeka komanso kukhazikika kwa kutentha kwambiri komanso kotsika, zinthu zomwe zimatumizidwa kunja ndi zabwino kuposa zinthu zapakhomo.
Kugula chubu choyenera cha PTFE sikuti kungosankha zinthu zosiyanasiyana pa ntchito zosiyanasiyana. Pali zambiri zoti musankhe wopanga wodalirika. Besteflon Fluorine plastic Industry Co., Ltd. yakhala ikupanga mapayipi ndi machubu apamwamba a PTFE kwa zaka 20. Ngati muli ndi mafunso ndi zosowa, chonde musazengereze kutifunsa kuti mudziwe zambiri za akatswiri.
