Obudde bw’okusiba (sintering time) bw’olugoye olwa PTFE olw’ebbugumu eringi bulina okufugibwa bitya?

I.OkutereezaOsipiidi y'Entambula y'Olugoye:Enkola y'Okufuga Omusingi

Enkolagana wakati w’embiro n’obudde: Sinteringtime(s)=obuwanvu bw’ekitundu ky’ebbugumu ekikola obulungi eky’oveni(m)÷sipiidi y’okutambula kw’olugoye (m/s).Okugeza, singa obuwanvu bw’ekitundu ekikola obulungi buba 15 era sipiidi ya layini eba 5m/mi n,obudde buba ddakiika ssatu.Ennyiriri z’okufulumya zikozesa ekikyusa frequency oba servomotors okutereeza obulungi sipiidi ya pull-rollers, okusobozesa enkyukakyuka z’obudde obw’amazima mu kiseera eky’okutambula.

Kulembeza okutereeza sipiidi: Ebbugumu lirina amalinertia.Mu kiseera ky'okufulumya emmeeza, ebbugumu lirina okuteekebwawo, era sipiidi ya layini erina okukola nga esinga okuddamu'mu kiseera.'Bwe kyetaagisa okulongoosa obulungi, okutereeza sipiidi kulina okukulembezebwa.

II.OkunnyonnyolaEnsengeka z’Ekiseera ky’Okusindika n’Ekitundu ky’Ebbugumu Ekikola

Kozesa350°Castheffectivesinteringthreshold: PTFEsaanuuka kumpi nga 327°C,naye amakoleroall levelyetaaga370–395°C.N’olwekyo,zone waggulu wa 350°Citegeezebwa nti ekikola ku interingzone.Ekiseera kyokka engoye ze zimala waggulu w’ebbugumu lino kibalirirwamu obudde obumala.

Engabanya y’ebbugumu mu bitundu ebingi: Preheatingzone(100–250°C)–eggyawo processsingidsandprevents bbugumu;Sinteringzone(360–395°C)–etuuka ku kusaanuuka;High-temperatureresettingzone(380–390°C)–ewummuza mu situleesi ey’omunda;Coolingzone(cooled wansi wa300°C)–tebabalibwamu intering time.

Okubala obudde bw’okubeera obulungi:Gabanya obuwanvu bwonna obw’ebitundu ebigwa ku ≥350°C ku sipiidi ya layini.Okugeza, singa obuwanvu bwonna obw’ebitundu buba waggulu wa 350°Cis10 era sipiidi eba 4m/min, obudde bw’okusiba obukola buba ddakiika 2.5.

III.Ebikwata ku BikozesebwaSsazaamuEkiseera ky’Ekigendererwa n’Ennongoosereza

Ebiwandiiko ebiseera by’okutabula(ku380–390°C): Ebika ebizito(0.08–0.13mm)–30–60seconds;Standardtypes(0.18–0.25mm)–1.5–3eddakiika;Ebika ebizito(0.35mmandawaggulu)–3–5 ddakiika oba okusingawo,nga kiragiddwa okuziyiza'okufumbibwa ebweru, ku mabbali g'empewo.'

Okuzuula n‟okutereeza: Obutamala kussa (amaanyi amatono, okuyiwa pawuda, enjatika entonotono)→kikendeeza ku sipiidi okutuuka ku budde;Okufukirira ekisukkiridde (okufuuka ekya kyenvu, okumenya, okunyiiza omukka omuzungu)→kyongera ku sipiidi okufunza ebbugumu eringi.

Okuwanyisiganya ebbugumu-obudde obwenkanankana: Okusiiba okw’ebbugumu eringi(395–405°C, makumi ga sikonda, akabi akasingako) oba ebbugumu eri wansi okuziika wansi(360–375°C, eddakiika 5–8,omutindo ogusinga okubeera omutebenkevu)byombi bisoboka.Omusingi gukuuma ebbugumu nga bwe lisinga okukulembeza era nga literedde sipiidi okusinziira ku.

Okukebera omutindo: Ebintu ebirina ebisaanyizo birabika nga byeru ng’amata era nga bitangalijja, nga biweweevu, ebitali bya mpeke;ebimyufu biraga nti bisukkiridde okufuumuuka, so nga butto w’ebitundu oba obuwunga obuyiwa biraga nti bifuuse wansi nteringtime.Singa amaanyi gano gamala naye ng’olugoye lufuuse bbugumu, kukulembeza okulongoosa obulungi ebbugumu ate nga mu ngeri esaanidde okendeeza ku budde.Kozesa ekipima ebbugumu erya frared okulondoola ebbugumu ly’emifaliso ku ngulu okukakasa nti obudde bwe bubeera waggulu wa 350°C butuukana n’ekyetaagisa.
