Maitiro ekugadzira ePTFE anonyanya kusanganisira anotevera 4 matanho makuru:
1. monomer synthesis
PTFEndeye polymerization ye tetrafluoroethylene (TFE) monomer polymerization yepolymer compounds.monomer synthesis yeTFE ndiyo nhanho yekutanga mukugadzirwa kwePTFE.Parizvino, indasitiri inonyanya kushandisa electrolytic fluorination nzira kugadzirira TFE monomer, kureva, anhydrous hydrogen fluoride uye ethylene pasi pemamwe mamiriro e electrolysis reaction kuti ibudise TFE monoma.
2.Polymerization reaction
TFE monomer pane imwe tembiricha uye kumanikidza, wedzera catalyst uye solvent, polymerization reaction.Munguva yekuitwa kwepolymerization, TFE monomer inoramba iine polymerized kuti igadzire yakakwira molecular uremu PTFE, tembiricha, kudzvanywa, catalyst mhando uye kusungirirwa kwepolymerization reaction uye zvimwe zvinhu zvinokanganisa huremu hwemamorekuru, chimiro uye zvimiro zvePTFE.
3.Post-kurapa
Mushure mekuita kwepolymerization kwapera, kurapwa-pashure kunodiwa kuti uwane yakachena PTFE zvigadzirwa.Kurapa mushure kunonyanya kusanganisira kugeza, kuomesa, kupwanya, sieving uye mamwe matanho ekubvisa catalysts, solvents uye mamwe tsvina kuti uwane yakachena PTFE resin particles.
4.Molding process
PTFE resin particles inoumbwa pasi pemamwe mamiriro kuti uwane inodiwaPTFE zvigadzirwa.Nzira dzekuumba dzinosanganisira extrusion, jekiseni kuumba, calendering uye zvichingodaro, maererano nezvinodiwa zvakasiyana zvezvigadzirwa kusarudza nzira yakakodzera yekuumba.Molding process tembiricha, kumanikidza, kumhanya kwekugadzirisa uye zvimwe zvinhu zvinokanganisa mashandiro uye kunaka kwezvigadzirwa zvePTFE.
Raw zvinhu zvePTFE
Polytetrafluoroethylene (PTFE) resin yakawanikwa netsaona nemasayendisiti eAmerica murabhoritari muna 1936, uye zvino nyika inogona kuburitsa PTFE munyika dzisingasviki makumi maviri, zhinji dzacho inyika dzakabudirira.China mu60s yekuziva tekinoroji yekugadzira uye kuona kugadzirwa, yave mutengi mukuru wePTFE, umo zvigadzirwa zvakaderera zvave zvakanyanya kupfuura kudiwa, asi zvigadzirwa zvakawanda zvepamusoro-soro zvichiri kuda kuvimba nekutengesa kubva kunyika dzakabudirira. .
China yazvino PTFE midziyo uye zvigadzirwa zvinonyanya kutengwa kubva kuUnited States, Japan, uye nyika dzeEurope.Nekuda kwemutengo wekufambisa uye kutenderera kwekupa, China kuunza iyo Japan yakanyanya kuwanda, uye kuJapan kupinza zvigadzirwa zvePTFE zvemhando yepamusoro kuti zvizadzise kudiwa kwepamba kwepamusoro-magumo.
Zvinoenderana nemhinduro-yemutengi wekupedzisira, zvigadzirwa musimba remagetsi rekushandisa chaiko kwemamiriro ekushanda, zvinokambaira kuramba uye yakakwirira uye yakaderera tembiricha kugadzikana, zvinhu zvinotengeswa kunze kwenyika zviri nani pane zvemumba.
Kutenga iyo chaiyo PTFE tubing haisi yekungosarudza zvakasiyana siyana zvekushandisa zvakasiyana.Zvimwe kusarudza mugadziri akavimbika.Besteflon Fluorine plastic Industry Co., Ltd. inyanzvi mukugadzirwa kwemhando yepamusoro yePTFE hoses nemachubhu kwemakore makumi maviri.Kana paine mibvunzo uye zvinodiwa, ndapota inzwa wakasununguka kutibvunza kune mamwe mazano ehunyanzvi.
