Gqibezela inkqubo yeMveliso yoShishino ye-PTFE Emulsion Impregnated Fiberglass Ilaphu

I-Jiangsu Aokai Materials eNtsha, umenzi welaphu we-PTFE wobushushu obuphezulu, uthatha inkqubo epheleleyo.

Ilaphu le-PTFE elinobushushu obuphezulu, ngokwekhemikhali elaziwa ngokuba yi- polytetrafluoroethylene (PTFE) ilaphu le-fiberglass egqunyiweyo , yimathiriyeli ebalaseleyo edibeneyo yepolymer. Ukuveliswa kwayo akuyona inkqubo yokugqoka elula, kodwa inkqubo yonyango ye-thermal kunye neekhemikhali. Ukuvelisa umgangatho ophezulu we-PTFE welaphu lobushushu obuphezulu, inkqubo engqongqo yamanqanaba amane iyafuneka: ukulungiswa kwelaphu elisisiseko, ukulungiswa kwesisombululo sokufakelwa, ukufakelwa okungundoqo kunye ne-sintering, kunye nonyango lwasemva..

Inqanaba loku-1: Unyango lwangaphambili lweFabric yeSiseko

Eli nqanaba limisela amandla oomatshini kunye nokunyaniseka kolwakhiwo lwelaphu lokugqibela le-PTFE.

Ukucocwa kwe-Thermal (i-Dewaxing) Umsonto we-fiberglass osetyenziselwa ukuluka ilaphu le-PTFE uqulethe ii-agent ze-organic sizeng ngexesha lokwenziwa. Ukuba azisuswanga, ezi arhente zithintela kakhulu ukubambelela kwiingubo ze-PTFE ezilandelayo. Ngoko ke, isinyathelo sokuqala kukutya isiseko sesiseko kwisithando somlilo esiphezulu (malunga ne-350 ° C) ngokukhawuleza ukukhupha i-dewaxing ukuqinisekisa ukucoceka kwe-fiberglass substrate.

Ukuguqulwa koMphezulu Ukuphucula amandla okudibanisa phakathi kwe-fiberglass kunye ne-PTFE yokwambathisa intlaka, ilaphu elisisiseko liphathwa nge-arhente yokudibanisa i-silane. Eli nyathelo linyusa kakhulu amandla e-peel interlaminar kwaye lithintele i-delamination okanye i-coating peeling kwimveliso egqityiweyo.

Inqanaba 2: Ukulungiswa kwe-PTFE Impregnation Emulsion

Iimpawu ezibonakalayo kunye neekhemikhali zelaphu lokugqibela zigqitywa kakhulu kweli nqanaba.

· Ukuxuba i-Emulsion Eyona nto isetyenziswayo ekrwada igxile kwi-PTFE yokusasazwa . Ngokweemfuno ezahlukeneyo zesicelo - ezifana nokusebenza okuphezulu okungabambekiyo kwimpahla yokubhaka ukutya okanye ukuxhathisa okuphezulu kweempahla zokukhulula - iifayili kunye nezongezo zongezwa ngokuchanekileyo kwi-emulsion. Isisombululo sofakelo esenziweyo sibalulekile ekuchazeni umgangatho welaphu lePTFE eligqityiweyo.

Inqanaba lesi-3: Ukumitha okungundoqo kunye nokuSintering

Le yinkqubo ephambili enika ilaphu le-PTFE ukusebenza kwalo okungaqhelekanga, okukholisa ukubandakanya imijikelo ephindaphindiweyo.

I-Impregnations ezininzi Ngaphantsi kolawulo loxinzelelo oluqhubekayo, ilaphu elisezantsi elifakwe ngaphambili lidlula ngokuphindaphindiweyo kwitanki yediphu egcwele i-emulsion ye-PTFE. Ukufezekisa ubukhulu obufunwayo kunye noxinaniso, umgca wemveliso wamkela inkqubo ye-cyclic: ukukhulelwa → ukomisa → sintering . Umjikelo ngamnye ngokuchanekileyo ukwandisa ubunzima bokugquma.

Ukomisa Ilaphu elifakwe phakathi eligqityiweyo lidlula kwi-oven yobushushu obuphantsi (malunga ne-100 ° C) ukususa ngobunono ukufuma. Ulawulo olungafanelekanga kweli nqanaba lula lubangela amaqamza okanye imingxunya ngexesha lokuntywila, oko kuthoba ngokunzulu ukusebenza kwe-insulation.

I-High-Temperature Sintering Le yintliziyo yenkqubo yokuvelisa. I-coating emanzi i-sintered malunga ne-380 ° C, ivumela amaqhekeza e-PTFE ukuba anyibilike ngokupheleleyo kwaye ahambe, enze ifilimu ekhuselayo. Ikhono lelaphu le-PTFE lokumelana nenkonzo yexesha elide kwi-260 ° C livela kwi-polymer chain recrystallization kweli nyathelo. Ilaphu le-sintered elingaphelelanga lixhomekeke ekuqhekekeni kunye nokulahlekelwa kweempawu ezinganamatheli.

Inqanaba lesi-4: Emva koNyango kunye noHlolo lweMveliso egqityiweyo

Emva kwe-sintering, ilaphu liqhuba iinkqubo ezingakumbi zokugqiba.

I-Hot-Press Setting kunye ne-Surface Treatment I-High-end ye-PTFE amalaphu (afana nalawo amabhanti okuhambisa) afakwe kwi-calendered ngee-roller ezitshisayo ukuze alulaze umphezulu kunye nokunciphisa uxinzelelo lwangaphakathi. Kumalaphu e-PTFE asetyenziswa kwi-laminates ye-copper-clad ephezulu-frequency, unyango olukhethekileyo lwe-corona lusetyenziswa ukunyusa uburhabaxa bomphezulu.

Inkqubo yokuLamination Kwi-high-end filtration applications, umaleko obhityileyo we-polytetrafluoroethylene eyandisiweyo (ePTFE) inwebu ye-microporous i-laminated phezu komhlaba, idala i-medium composite filter medium kunye nokusebenza okuphezulu kokucoca.

I-Aokai New Materials iphumeza ukuhlolwa komgangatho ongqongqo. Iimveliso zokugqibela zivavanywa kusetyenziswa i-grammage tester, i-high-voltage tester, kunye ne-tensile tester. Kuphela ziimveliso ezinobunzima obufanayo, ezingenamingxunya, kwaye zithobela iimfuno zokumelana nombane zikhutshwa njengempahla efanelekileyo.

Olu lwazi lungasentla lunikezelwe nguJiangsu Aokai New Materials Technology Co., Ltd.

Ukufumana iinkcukacha ezicacileyo, iimeko zesicelo kunye nezisombululo ezilungelelanisiweyo zoluhlu olupheleleyo lweemveliso - kubandakanywa amalaphu e-PTFE aphezulu obushushu, i-PTFE i-tapes high-temperature tapes, i-PTFE high-temperature mesh belts, amabhanti angenamthungo omatshini wokuxubha, amalaphu e-PTFE asecaleni elinye, i-high-temperature-high-temperature resistant, i-glassware-conveyort-conveyor-conveyort-iglasi nceda uthinte ngakumbi
