Kugadzira iyo TFE
1 Vagadziri vePTFE vanotanga nekugadzira TFE.Izvo zvitatu zvinongedzo zveTFE, fluorspar, hydrofluoric acid, uye chloroform zvinosanganiswa mukamuri rekuita makemikari rinopisa kusvika pakati pe1094-1652 ° F (590-900 ° C).Gasi rinozobuda rinobva ratonhodzwa, uye rakanyungudutswa kubvisa chero tsvina.
Kumiswa Polymerization
2 Imba yekupindura inozadzwa nemvura yakacheneswa uye reaction agent kana initiator, kemikari inokonzeresa kuumbwa kwepolymer.Iyo TFE yemvura inopinzwa mukamuri yekupindura.Sezvo TFE inosangana neanotangisa, inotanga kuita polymerize.Iyo PTFE inoguma inoumba zviyo zvakasimba zvinoyangarara pamusoro pemvura.Sezvo izvi zviri kuitika, the reaction chamber inozununguswa nemichina.Kuita kwemakemikari mukati mekamuri kunopa kupisa, saka kamuri inotonhodzwa nekutenderera kwemvura inotonhora kana chimwe chinotonhorera mubhachi rakatenderedza kunze kwayo.Kudzora otomatiki kudzima kupihwa kweTFE mushure mekunge humwe huremu mukati mekamuri hwasvika.Mvura inodonhedzwa kunze kwekamuri, ichisiya tsvina yetambo PTFE inotaridzika senge kokonati yakagayiwa.
3 Tevere, iyo PTFE inoomeswa uye kudyiwa muguyo.Chigayo chinopwanya PTFE nemashizha anotenderera, ichigadzira chinhu chine kuenderana kwehupfu hwegorosi.Upfu hwakatsetseka hunonetsa kuumba.Iine "kuyerera kwakashata," zvichireva kuti haigone kugadziriswa nyore mumichina otomatiki.Kufanana nehupfu hwegorosi husina kupepetwa, inogona kunge iine mapundu uye homwe dzemhepo.Saka vagadziri vanoshandura iyi poda yakanaka kuita magranules akakura nemaitiro anonzi agglomeration.Izvi zvinogona kuitwa nenzira dzakawanda.Imwe nzira ndeyekusanganisa iyo PTFE poda ine solvent yakadai seacetone uye kuidonhedza mudhiramu rinotenderera.Iyo PTFE tsanga dzinonamatira pamwechete, dzichigadzira mapellet madiki.Mapellets anobva aomeswa muchoto.
4 Iyo PTFE pellets inogona kuumbwa kuita zvikamu uchishandisa nzira dzakasiyana siyana.Zvisineyi, PTFE inogona kutengeswa yakawanda yakatogadzirwa kare kuita anonzi mabheti, ari masilinda akasimba ePTFE.Mabhiridha anogona kunge akareba 5 ft (1.5 m).Izvi zvinogona kutemwa kuita masheets kana mabhururu madiki, kuti uwedzere kuumba.Kugadzira iyo billet, PTFE pellets inodururwa mune cylindrical Stainless simbi mold.Iyo mold inotakurwa pamuchina we hydraulic, chiri chinhu chakafanana nekabhati hombe ine huremu hwegondohwe.Gondohwe rinodonhera pasi muforoma uye rinoshandisa simba paPTFE.Mushure meimwe nguva yenguva, mold inobviswa kubva mukudhinda uye PTFE haina kuumbwa.Inobvumirwa kuzorora, yozoiswa muchoto kuitira nhanho yekupedzisira inonzi sintering.
5 The molded PTFE inodziiswa muchoto chinopisa kwemaawa akati wandei, kusvika yasvika zvishoma nezvishoma tembiricha inosvika 680°F (360°C).Izvi zviri pamusoro pekunyungudika kwePTFE.Iyo PTFE zvimedu zvinobatana uye zvinhu zvinova gel-senge.Zvadaro PTFE inotonhodzwa zvishoma nezvishoma.Billet rakapedzwa rinogona kutumirwa kune vatengi, vanozocheka kana kuveura muzvidimbu zviduku, kuti vawedzere kushandiswa.
Dispersion polymerization
6 Polymerization yePTFE nenzira yekuparadzira inotungamira kune yakatsetseka poda kana paste-yakafanana chinhu, iyo inonyanya kubatsira pakuputira uye kupera.TFE inounzwa mumvura yakazadzwa reactor pamwe chete nekemikari yekutanga.Panzvimbo yekuzununguswa zvine simba, sepakumiswa, iyo reaction chamber inongobvongodzwa zvinyoro nyoro.Iyo PTFE inoumba kuita mabeads madiki.Imwe yemvura inobviswa, nekusefa kana nekuwedzera makemikari anoita kuti PTFE bead dzigadzikane.Mhedzisiro yacho chinhu chine mukaka chinonzi PTFE dispersion.Inogona kushandiswa semvura, kunyanya mumashandisirwo akaita semachira ekupera.Kana kuti inogona kuomeswa kuita upfu hwakatsetseka hunoshandiswa kunaya simbi
