I. IiMfuno eziSisiseko zoMgangatho wokuPholisa
Ukudlula ngokukhawuleza kwindawo enovelwano lwecrystallization Indawo yokunyibilika ye-PTFE yi-327°C, kwaye iqondo lobushushu eliqhelekileyo le-sintering lisuka kwi-380°C ukuya kwi-400°C. Ngexesha lokunciphisa ubushushu, imfuno engundoqo kukuwela ngokukhawuleza indawo yokushisa malunga ne-310 ~ 315 ° C apho izinga le-crystallization liphezulu kakhulu.
Iindlela zokusebenza ezicetyiswayo Kwakamsinyane nje emva kokuphuma kwiziko lokutshisa, sebenzisa ukupholisa umoya ngenkani, ukupholisa umoya ocinezelweyo, okanye sebenzisa iirola zokupholisa / izixokelelwano zokupholisa amanzi ukuhlisa ngokukhawuleza ubushushu belaphu ngaphantsi kwama-250°C.
Izalathi zereferensi yezinga lokupholisa Ngokuxhomekeke kubukhulu bemveliso, izinga lokupholisa jikelele aliyi kuba ngaphantsi kwe-30~50°C/min. Kwilaphu elincinci lobushushu obuphezulu (0.08mm ~ 0.25mm), ukupholisa umoya kunokufezekisa izinga lokupholisa ngaphezu kwe-100 ~ 200 ° C / min, okwenza ukuba kudlule ngokukhawuleza kwindawo ebalulekileyo ye-crystallization.
ICrystallinity imisela iipropathi zemveliso ezingundoqo Iindlela zokupholisa zilawula ngokuthe ngqo ubukhazikhazi be-PTFE, obuyalela ngakumbi iimpawu eziphambili zokugquma ezibandakanya ukuguquguquka, ukuncamathela kunye nokusebenza okungabambekiyo.
Ukuthelekiswa koMsebenzi phakathi kokuKhawuleza kunye nokuPholisa okucothayo
Imo yokupholisa |
Ubukhazikhazi |
Ukwalekwa kokuziphatha koMsebenzi |
Ukupholisa ngokukhawuleza (Ukucima) |
Phantsi (malunga nama-45~50%) |
Ithambile, ukuqina okugqwesileyo, umphezulu ogudileyo, ukuncamathela olomeleleyo, ipropathi ephezulu engancamathelanga, imelana nedelamination kunye nokuqhekeka. |
Ukupholisa okucothayo (Ukupholisa iziko) |

Inkcazo yeMicrostructural Ukupholisa ngokukhawuleza kuthintela ukukhula kwee-spherulites ezinobungakanani obukhulu kwaye zenze isakhiwo esihle se-microcrystalline. Oku kunika ifilimu ye-PTFE i-denser kunye ne-ductile eninzi, ngelixa unciphisa uxinzelelo olushiyekileyo phakathi kwe-coating kunye ne-fiberglass substrate.
III. Amanqaku oLawulo aPhambili kwiMveliso yoMninzi
Ukuqinisekisa ukupholisa okufanayo Ukupholisa ukuhamba komoya okanye iirola zokupholisa kufuneka zigcine ubushushu obulinganayo kububanzi belaphu. Ukungalingani kwecrystallinity yendawo kuya kubangela umphezulu onamabala okanye iziphene ezishwabeneyo.
Kuphephe ukothuka okugqithisileyo kwe-thermal Kwilaphu elishinyeneyo elinobushushu obuphezulu (0.5mm nangaphezulu), ukutshiza ngokuthe ngqo kwamanzi okanye ukudibana kwangoko neerola ezibanda kakhulu kunokubangela uguquko olumandla olubangelwa kukushwabana kobushushu obungahambelaniyo phakathi kwesubstrate kunye nokugquma. Eyona ndlela ikhethwayo yokuhamba komsebenzi kukuphola komoya ongaphantsi kwe-250°C phambi kokupholisa ngakumbi.
Ulawulo olupholileyo lwe-multi-pass sintering Kwi-multi-impregnation kunye neenkqubo ezininzi ze-sintering, ukupholisa ngokukhawuleza okuphakathi kwamkelekile kumjikelo ophakathi we-sintering. Nangona kunjalo, inyathelo lokugqibela lokucoca umphezulu kufuneka lamkele ukupholisa ngokukhawuleza ukuze kukhuseleke ukusebenza okuphezulu komphezulu wokusebenza.
IV. Isishwankathelo esingundoqo
1. Ukupholisa okuKhawulezayo kunyanzelekile kwisithuba se-PTFE sokufaka ilaphu ukwenza i-PTFE etyhidiweyo itsibe indawo yobushushu obuphezulu becrystallization ngokukhawuleza.
2. Ukupholisa ngokukhawuleza kuvelisa i-low-crystallinity microcrystalline structure, eyona nto ingundoqo kwi-flexibility ebalaseleyo, ukuchasana nokugoqa kunye nokusebenza kwexesha elide lokungagungqi.
3. Lawula ngokungqongqo ukufana kokupholisa, ukuthintela ukothuka kwe-thermal, kunye nokulungelelanisa iishedyuli zokupholisa ze-multi-stage sintering ukuzinzisa umgangatho wemveliso ongaguqukiyo.
