Txawm hais tias PTFE muaj ntau qhov zoo, nws txoj kev tsim khoom kuj txawv ntawm lwm cov yas.Teflon molded cov khoom siv Teflon ncua kev kawm resin nyob rau hauv ib tug hlau pwm, nias rau ntawm ib tug xovxwm los tsim ib tug dawb paug, thiab ces sintered.Cov txheej txheem molding yog raws li nram no.
Txawm hais tias PTFE muaj ntau qhov zoo, nws txoj kev tsim khoom kuj txawv ntawm lwm cov yas.Teflon molded cov khoom siv Teflon ncua kev kawm resin nyob rau hauv ib tug hlau pwm, nias rau ntawm ib tug xovxwm los tsim ib tug dawb paug, thiab ces sintered.Cov txheej txheem molding yog raws li nram no:
Kev ziab → hmoov → hnyav → nias → sintering → shaping
1. Qhuav: Nyob rau hauv tus txheej txheem ntawm kev thauj mus los thiab tuav, PTFE resin yog yooj yim damp vim yog kev tuav pov hwm tsis zoo (lub cev muaj kev cuam tshuam rau cov dej noo ntau dua thaum huab cua kub siab nyob rau lub caij ntuj sov), thiab cov hmoov resin muaj cov dej noo, uas tuaj yeem txo cov dej noo. noo noo thaum lub sij hawm high-temperature sintering txheej txheem.evaporation ua rau cov khoom pov tseg tau teev tseg.Yog li ntawd, PTFE resin hmoov yuav tsum tau qhuav nyob rau hauv ib hom qhuav ua ntej cov hmoov.
2. Cov khoom siv hmoov: qhuav cov hmoov resin nyob rau hauv chav tsev kub, sib tov cov hmoov agglomerated pov tseg nrog txoj kev qhuav, thiab siv nws thaum nias.
3. Kev hnyav: Kev hnyav kuj yog ib kauj ruam tseem ceeb.Yog tias qhov siab ntawm cov khoom lag luam yuav tsum ua kom zoo ib yam, nws yog qhov tsim nyog los xyuas kom meej tias cov khoom hnyav ntawm txhua yam khoom yog tib yam nyob rau hauv tib lub pwm thiab tib lub siab.
4. Nias: Muab cov khoom hnyav rau hauv cov kab noj hniav ntawm cov pwm, muab tso rau ntawm cov xovxwm, nias maj mam raws li qhov yuav tsum tau ua, thiab raws li qhov loj thiab tuab ntawm cov khoom, ua kom lub qhov cua kom zoo thaum lub sij hawm cov txheej txheem pressurization.Thiab tom qab ncav cuag lub siab, qhov loj ntawm cov khoom yog khaws cia kom zoo, feem ntau tsis pub dhau 0.5-15 feeb.
5. Sintering: Muab cov nias PTFE dawb paug rau hauv lub qhov cub sintering raws li qhov yuav tsum tau ua, kaw lub qhov cub qhov cub, thiab raws li ib qho txheej txheem sintering thiab qhov kub thiab txias, qhov sintered dawb paug yuav tsum tau ua.PTFE khoom.
6. Shaping: Thaum lub sij hawm shaping, ib tug tej yam txoj kev yog siv los kho cov qub duab ntawm cov khoom nrog ib tug loj deformation tom qab sintering.
