Nakuba i-PTFE inezinzuzo eziningi, indlela yayo yokukhiqiza nayo ihlukile kwamanye amapulasitiki.Imikhiqizo ebunjiwe ye-Teflon isebenzisa i-Teflon suspension resin esikhunjeni sensimbi, icindezelwe ngomshini ukuze yenze okungenalutho, bese i-sintered.Inqubo yokubumba imi kanje.

Ukomisa → impushana → ukukala → ukucindezela → ukucwilisa → ukubumba
1. Ukomisa: Ngesikhathi sokuthutha nokugcinwa, i-PTFE resin iba manzi kalula ngenxa yokugcinwa ngendlela engafanele (umzimba ungenwa kalula umswakama lapho izinga lokushisa lomoya liphezulu ehlobo), futhi i-resin powder iqukethe umswakama, onganciphisa umswakama. umswakama ngesikhathi senqubo ye-sintering ephezulu yokushisa.Ukuhwamuka kubangela ukuthi kufakwe udoti ohlwini.Ngakho-ke, i-PTFE resin powder kufanele yomiswe ngohlobo olomile ngaphambi kwempushana.
2. Impahla yempushana: yomisa impushana ye-resin ekamelweni lokushisa, hlanganisa imfucumfucu ye-agglomerated ngendlela eyomile, futhi uyisebenzise lapho ucindezela.
3. Ukukala: Ukukala futhi kuyisinyathelo esibalulekile.Uma ukuphakama komkhiqizo kufanele kuhambisane, kuyadingeka ukuqinisekisa ukuthi isisindo sempahla yomkhiqizo ngamunye siyafana ngaphansi kwesikhunta esifanayo kanye nokucindezela okufanayo.
4. Ukucindezela: Faka impahla enesisindo emgodini wesikhunta, uyibeke emshinini wokucindezela, cindezela kancane ngokuhambisana nokucindezela okudingekayo, futhi ngokusho kobukhulu nobukhulu bomkhiqizo, phuma kahle ngesikhathi senqubo yokucindezela.Futhi ngemva kokufinyelela ingcindezi ebekiwe, ubukhulu bomkhiqizo bugcinwa kahle, ngokuvamile phakathi kwemizuzu engu-0.5-15.
5. I-Sintering: Beka i-PTFE ecindezelwe ingenalutho esithandweni somlilo njengoba kudingekile, vala umnyango wesithando somlilo, futhi ngokuya ngenqubo ethile yokucwilisa kanye nezimfuneko zokushisa, okungenalutho okuhlanganisiwe kubaPTFE umkhiqizo.
6. Ukubunjwa: Ngesikhathi sokubunjwa, indlela ethile isetshenziselwa ukubuyisela isimo sangempela somkhiqizo nge-deformation enkulu ngemva kokucwiliswa.
