Kunyangwe PTFE ine zvakawanda zvakanakira, nzira yekugadzira yayo yakasiyanawo nemamwe mapurasitiki.Zvigadzirwa zveTeflon zvakaumbwa zvinoshandisa Teflon kuturika resin muforoma yesimbi, yakatsikirirwa pamuchina kuti iite isina chinhu, yobva yasiiwa.The molding process ndeiyi inotevera.
Kunyangwe PTFE ine zvakawanda zvakanakira, nzira yekugadzira yayo yakasiyanawo nemamwe mapurasitiki.Zvigadzirwa zveTeflon zvakaumbwa zvinoshandisa Teflon kuturika resin muforoma yesimbi, yakatsikirirwa pamuchina kuti iite isina chinhu, yobva yasiiwa.Iyo molding process ndeiyi inotevera:
Kuomesa → hupfu → kuyera → kudzvanya → sintering → kuumba
1. Kuomesa: Mukufambisa kwekutakura nekuchengetedza, PTFE resin inonyorova nyore nyore nekuda kwekuchengetedza kusina kunaka (muviri unonyanya kubatwa nehunyoro kana kutonhora kwemhepo kuchikwira muzhizha), uye resin powder ine unyoro, iyo inogona kuderedza unyoro panguva yekupisa-kupisa sintering process.Evaporation inokonzeresa kuti zvinoraswa zvinyorwe.Nokudaro, PTFE resin powder inofanira kuomeswa mumhando yakaoma pamberi pehupfu.
2. Hupfu hwezvinhu: omesa resin poda patembiricha yekamuri, sanganisa agglomerated poda tsvina nenzira yakaoma, uye shandisa kana uchidzvanya.
3. Kuyera: Kuyera idanho rinokoshawo.Kana kureba kwechigadzirwa kuchizoenderana, zvinodikanwa kuve nechokwadi kuti huremu hwezvinhu zvechigadzirwa chimwe nechimwe hwakafanana pasi pekuumbwa kumwechete uye kudzvanywa kwakafanana.
4. Kudzvanya: Isai zvinhu zvakayerwa mugomba remuumbi, zviise pamuchina, dzvanya zvishoma nezvishoma maererano nekumanikidza kunodiwa, uye maererano nehukuru uye hupamhi hwechigadzirwa, buda zvakanaka panguva yekumanikidza.Uye mushure mekusvika kumanikidziro akasarudzwa, ukuru hwechigadzirwa hunochengetwa zvakanaka, kazhinji mukati memaminitsi 0.5-15.
5. Sintering: Isa yakadzvanywa PTFE isina chinhu muchoto chekupisa sezvinodiwa, vhara gonhi rechoto, uye maererano neimwe nzira yekupisa uye tembiricha zvinodiwa, iyo sintered isina chinhu inovaPTFE chigadzirwa.
6. Kuumba: Panguva yekugadzira, imwe nzira inoshandiswa kudzorera chimiro chepakutanga chechigadzirwa nedeformation yakakura mushure mekupisa.
