Ndi chitukuko cha umisiri ndi chuma, ptfe wakhala ntchito m'minda zambiri, ndipo wakhala mfundo yofunika kwambiri kuthetsa umisiri ambiri kiyi mu kafukufuku wa sayansi, minda ya asilikali ndi boma ndi kusintha luso kupanga mlingo.Kuti mosalekeza bwino kupanga dzuwa la polima ptfe, tinayamba kutengera patsogolo kupanga ndondomeko, amene ali oyenera mkulu viscoelastic zakuthupi -- Ram-nkhonya extrusion.
Ndi chitukuko cha umisiri ndi chuma, ptfe wakhala ntchito m'minda zambiri, ndipo wakhala mfundo yofunika kwambiri kuthetsa umisiri ambiri kiyi mu kafukufuku wa sayansi, minda ya asilikali ndi boma ndi kusintha luso kupanga mlingo.Kuti mosalekeza bwino kupanga dzuwa la polima ptfe, tinayamba kutengera patsogolo kupanga ndondomeko, amene ali oyenera mkulu viscoelastic zakuthupi -- Ram-nkhonya extrusion.
Malinga ndi mfundo ya "forging", plunger stamping extruder makamaka imatenga plunger yokhala ndi gawo laling'ono lamtanda komanso kupondaponda pafupipafupi kwambiri kukankhira zinthu mumgolo wa extruder.Poyerekeza ndi chikhalidwe hayidiroliki mzati extruder, izo ali ndi makhalidwe a pafupipafupi mitundu mitundu, zabwino Sungunulani plasticizing tingati, zabwino mankhwala khalidwe, zida zosavuta ndi ndondomeko.
Malinga ndi kupanga makhalidwe aRam-nkhonya extruder, njira ya extrusion imawunikidwa ndikuphunziridwa.The thupi chitsanzo cha lonse extrusion ndondomeko ya plunger nkhosa extruder wakhazikitsidwa, amene lagawidwa zigawo zisanu: olimba kudya gawo, kusungunuka gawo, shunt gawo, kupanga gawo ndi kuzirala gawo.Chikoka cha kutalika kwa kufa ndi kugwedezeka kwamphamvu pafupipafupi panjira ya extrusion kudawunikidwa.Zotsatira za kusanthula zikuwonetsa kuti: ngakhale pali kusinthasintha kwakukulu kwapakhomo la kusungunula, koma kukakamiza konseko kuchokera pakulowera kupita kumaloko kunachepetsedwa pang'onopang'ono, motero kuwonetsetsa kuti kukakamiza kokwanira kukankhira zinthuzo, ndikuyandikira kwambiri. kumaliza kuthamanga nkhungu kutulutsa ndi kusinthasintha kwa liwiro ndikocheperako, kotero kumatha kuwonetsetsa kupitiriza kwa extrusion, potsiriza kupeza zinthu zabwino.Kutalika ndi kupondaponda pafupipafupi kwa kufa kumakhala ndi mphamvu zina pa kuthamanga kwa extrusion ndi liwiro.Chifukwa cha kukhuthala kwapamwamba kwa PTFE, kufa kwautali kuyenera kusankhidwa, ndipo kupondaponda pafupipafupi pakati pa 5-6hz ndikoyenera.
Ram plunger extrusion machining polima PTFE ndi njira yatsopano yopangira makina, koma m'kati mwazinthu zopangira zinthu, komanso sangasiye kutuluka kwa zinthu ndi mapindikidwe, khalidwe la rheological ndi lamulo, kumvetsetsa ndondomeko ya kuumba ndondomeko yosankhidwa bwino, ntchito ndi kukhathamiritsa kulamulira. ndi kukonza zida akamaumba ali zofunika kwambiri zothandiza tanthauzo.Kupondaponda kwa plunger si njira yokhazikika, ndipo pali kugwedezeka pakupondaponda.Ndikofunikira kwambiri kuphunzira momwe ma polima amayankhira pochita kugwedezeka, ndikukambirana momwe gawo la vibration lingakhudzire kukhazikika kwa kayendedwe kake, kuti muphunzire kusinthika kwa zida za polima ndikuwongolera kupanga.
