I-Sintering linyathelo elibalulekileyo apho amasuntswana e-PTFE anyibilika, aqukuqela, kwaye adibanise kwifilimu eqhubekayo. Kodwa ikwalinqanaba apho ukucaba kulahleka ngokulula. Uxinzelelo olungalinganiyo, utshintsho olukhawulezayo lobushushu, okanye ukungakwazi kuzibamba ngokwaneleyo kunokubangela imibimbi engaguqukiyo, imiphetho yamaza, kunye ne-warpage engenakulungiswa emva koko.
Umgaqo ongundoqo wokugcina ukucaba lulawulo oluchanekileyo kuxinzelelo, ubushushu, kunye neendlela zokuzibamba -ukwenza ukubunjwa okulungelelanisiweyo kwe-fiberglass substrate kunye ne-PTFE etyhidiweyo yokwaleka.
Aokai PTFE (Ilaphu le-PTFE fiberglass ) liphuhlise iinkqubo zokuqina eziqinileyo zokuqinisekisa ukugcwala okungaguqukiyo. Esi sikhokelo sibandakanya amanqaku amahlanu olawulo olubalulekileyo lwe-flatness ezinzileyo kwimveliso yobuninzi.
Ukuthintelwa kweZixhobo - Umatshini weStenter unyanzelekile
Esi sesona sisombululo singundoqo sokuthintela ukushwabana kwe-weft kunye ne-wavy selveges. I -pin stenter (okanye i-clip stenter) kufuneka ifakwe ngaphakathi kwesithando somlilo.
1. Ukubunjwa ngokunqamlezayo
Iipleyiti zePin zigqobhoza imiphetho yelaphu. Ngokuhlengahlengisa ububanzi bomzila wamatyathanga okuhambisa, ukunyanzeliswa kwe-mild transverse kusetyenziswa - okanye ubuncinci, ububanzi belaphu lokuqala bugcinwa ukuchasana noxinzelelo lwe-thermal shrinkage ye-substrate phantsi kobushushu obuphezulu. Ngaphandle kwesi sithintelo, ububanzi belaphu buyancipha kwaye imiphetho ibe yi-wavy.
2. Ulawulo lwexesha elide
Umahluko wesantya esichanekileyo phakathi kweerola zangaphambili nezingasemva kunye nolawulo lokuxinezeleka oluvaliweyo luzisa uxinzelelo oluphezulu olusezantsi kunye noluzinzileyo lwelongitudinal:
INzululwazi yoBubushushu beNzululwazi-Ukufudumeza kweGradient kunye nokupholisa okucothayo
Igophe elithambekileyo lokufudumeza okuthambileyo, ukunyibilika okupheleleyo, kunye nokupholisa okucothayo kuyafuneka ukuze kupheliswe umothuko wobushushu kunye ne-warpage ebangelwa luxinzelelo.
1. Indawo yokufudumeza
Ubushushu bunyuka ngokucothayo malunga nenqanaba lokunyibilika kwe-PTFE (327°C) ukulungelelanisa ubushushu belaphu langaphakathi kunye nomphezulu. Ukushisa kwendawo okanye ukunyuka kweqondo lokushisa ngokukhawuleza kukhokelela ekunciphiseni okungalinganiyo kunye nokunyuka okusisigxina. Injongo kukuvumela ubushushu bungene ngokulinganayo kubunzima belaphu phambi kokuba kuqale ukunyibilika ngokupheleleyo.
2. Indawo yokubamba iSintering
Ubushushu obuqhubekayo bugcinwe kwi- 380-400 ° C ngexesha elaneleyo lokuhlala. Oku:
Inyibilikisa ngokupheleleyo amasuntswana ePTFE abe yifilimu eqhubekayo
Ikhupha uxinzelelo lwangaphakathi olushiyekileyo lwe-fiberglass phantsi kwemeko ethe tyaba
Iqinisekisa ukudibanisa okupheleleyo kunye noxinaniso
3. Indawo yokupholisa – isoloko ingahoywa, kodwa ibalulekile
Eli linqanaba apho i-warpage iqhele ukwenzeka. Ukupholisa okucothayo kuyadingeka ngelixa kugcinwa ukuthintela i-sterter de ubushushu buhla ngaphantsi kwe-PTFE crystallization point (malunga ne- 310 ° C ).
Umgaqo obalulekileyo: Ukupholisa umoya okunyanzeliswa ngokukhawuleza kudala ukushwabana okungahambelaniyo phakathi kokutyabeka kunye ne-substrate - okukhokelela ekujikeni okuzingileyo okanye ukugoba ama-curling angenako ukucaba emva koko. Gcina ilaphu lithintelwe de i-PTFE ikhazimle ngokupheleleyo kwaye itshixiwe kwimilo yayo yokugqibela.
I-Flatness ngexesha le-sintering ixhomekeke kwinto eyenzekayo ngaphambi kokuba ilaphu lingene eziko.
1. Ukuncipha kwangaphambili kwendwangu yesiseko
Phambi kokumiliselwa kwe-PTFE, ilaphu le-fiberglass lifumana i-dewaxing yobushushu obuphezulu kunye nokuncipha kwangaphambili ukususa uxinzelelo olushiyekileyo. Oku kunciphisa kakhulu i-shrinkage yesibini ngexesha le-sintering kwaye ibeka isiseko se-flatness ephezulu.
Inqaku le-Aokai PTFE: Ngaphandle kokunciphisa kwangaphambili, i-fiberglass iya kuzama ukwenza isivumelwano ngexesha le-sintering - ukulwa nokunqanda ukunqanda kunye nokubangela ukusabalalisa koxinzelelo olungalinganiyo.
Umaleko omilisiweyo we-PTFE kufuneka ubonise ubukhulu obuhambelanayo kulo lonke ilaphu. Ukwaleka okungalinganiyo kubangela ukwahlukana kwexesha lokunyibilika - iindawo ezibhityileyo zinyibilika ngokukhawuleza kuneendawo ezishinyeneyo - zivelisa amaqhuqhuva oxinzelelo afana nokuthungwa kwamaxolo e-orenji kunye nokonakalisa ukucaba.
Ukulawulwa ngokuchanekileyo kokukhulelwa, ukugquma i-blade kagqirha, kunye neenkqubo zokugoqa ziyimfuneko.
Nokuba ubungakanani obuncinci (0.01mm) bunokubangela iziphene ezibonakalayo kumphezulu.
ULungiselelo lokuhamba komoya kunye neeRola ezichanekileyo zeSikhokelo
1. Uyilo lokujikeleza komoya oshushu
I-Adopt counter-blow-top-and-bottom counter-blow okanye iyunifomu ejikeleza umoya oshushu ngaphakathi kwesithando somlilo ukunqanda ukuhamba komoya okunecala elinye elibetha ngokuthe ngqo ilaphu - elibangela amanqaku e-flutter. Inkxaso ye-cushion yomoya ezinzileyo kwii-oveni ezithe tyaba ithintela ukugoba kwelaphu phezu kobude obunqunyanyisiweyo.
2. Ukuhambelana okungqongqo kwee-rollers
Zonke iirola zesikhokelo kunye neeroli zoxinzelelo kufuneka zigcine ukuhambelana okuphezulu kakhulu kwaye zihlale zicocekile ngaphandle kweentsalela ezincangathi:
Ukuphambuka kwelaphu elincinci kukhokelela kuxinzelelo olungalinganiyo kumacala omabini kunye nemibimbi emacala omabini
Inkqubo yokulungiswa komphetho ozenzekelayo iya kuxhotyiswa
Ukucocwa rhoqo kuthintela ukwakhiwa kwe-adhesive ebangela ukuba utshintsho lwe-tension yendawo
Ukuthe tyaba okugqibeleleyo akuzuzwa ngamandla ocinezelo lwangaphandle. Endaweni yoko, phantsi kothintelo oluchanekileyo lweplani yomatshini we-stenter, ubushushu obufanayo kunye noxinzelelo nyibilika kwaye udibanise i-PTFE yokwambathisa kunye ne-fiberglass substrate ibe yimbumba egudileyo, kunye nalo lonke uxinzelelo olushiyekileyo lukhutshwe ngokupheleleyo ngokupholisa ngokuthe ngcembe.
Ukutenxa kulo naliphi na ikhonkco lenkqubo enye ekugqibeleni liyakubonakala njengomgangatho welaphu ongalinganiyo.
