Nangona i-PTFE ineenzuzo ezininzi, indlela yayo yokuvelisa yahlukile kwezinye iiplastiki.Iimveliso ezibunjiweyo zeTeflon zisebenzisa i-resin ye-Teflon yokumiswa kwi-mold yensimbi, icinezelwe kwi-press ukuze yenze into engenanto, kwaye i-sintered.Inkqubo yokubumba ngolu hlobo lulandelayo.
Nangona i-PTFE ineenzuzo ezininzi, indlela yayo yokuvelisa yahlukile kwezinye iiplastiki.Iimveliso ezibunjiweyo zeTeflon zisebenzisa i-resin ye-Teflon yokumiswa kwi-mold yensimbi, icinezelwe kwi-press ukuze yenze into engenanto, kwaye i-sintered.Inkqubo yokubumba imi ngolu hlobo lulandelayo:
Ukomisa → umgubo → ubunzima → ukucofa → ukuthoba → ukubumba
1. Ukomisa: Kwinkqubo yokuthutha kunye nokugcinwa, i-PTFE resin ilula ngokulula ngenxa yokugcinwa ngendlela engafanelekanga (umzimba usengozini yokufuma xa ubushushu bomoya buphezulu ehlotyeni), kwaye i-resin powder iqulethe ukufuma, okunokunciphisa ukufuma. ukufuma ngexesha lobushushu obuphezulu benkqubo ye-sintering.Umphunga ubangela ukuba iimveliso zenkunkuma zidweliswe.Ke ngoko, i-PTFE resin powder kufuneka yomiswe ngohlobo olomileyo phambi komgubo.
2. Izinto zomgubo: yomisa i-resin powder kwiqondo lokushisa, xuba inkunkuma ye-agglomerated powder kunye nendlela eyomileyo, kwaye uyisebenzise xa ucinezela.
3. UkuWayisha: Ukuweyisha kwakhona linyathelo elibalulekileyo.Ukuba ukuphakama kwemveliso kufuneka kuhambelane, kuyimfuneko ukuqinisekisa ukuba ubunzima bezinto eziphathekayo kwimveliso nganye bufanayo phantsi kwesikhunta esifanayo kunye noxinzelelo olufanayo.
4. Ukucinezela: Faka izinto ezilinganisiweyo kwi-cavity ye-mold, uyibeke kwi-press, cinezela ngokucothayo ngokuhambelana noxinzelelo olufunekayo, kwaye ngokuhambelana nobukhulu kunye nobukhulu bemveliso, vula ngokufanelekileyo ngexesha lenkqubo yoxinzelelo.Kwaye emva kokufikelela kuxinzelelo oluchongiweyo, ubungakanani bemveliso bugcinwe ngokufanelekileyo, ngokuqhelekileyo ngaphakathi kwe-0.5-15 imizuzu.
5. I-Sintering: Beka i-PTFE ecinezelweyo ingenanto kwiziko lokutshisa njengoko kufuneka, vala ucango lwesithando somlilo, kwaye ngokwenkqubo ethile ye-sintering kunye neemfuno zobushushu, i-sintered blank iba yi-sintered blank.PTFE imveliso.
6. Ukubunjwa: Ngexesha lokubunjwa, indlela ethile isetyenziselwa ukubuyisela ubume bokuqala bemveliso kunye ne-deformation enkulu emva kokucoca.
