Idityaniswa njani i-PTFE yokwambathisa kwilaphu le-fiberglass substrate kwilaphu le-Teflon lobushushu obuphezulu?

Njani iPTFECoatingonTeflonHigh-TemperatureLathInamathela kwiFiberglassFabric?

I-PTFE(ipolytetrafluoroethylene)inamandla aphantsi kakhulu phezu kobuso ayaziwa ngendlela engaziwayo'ayinantonga'izinto.Ngoko ke, ayinakudityaniswa ngokwekhemikhali ngokuthe ngqo kwifayibha yeglasi yefabriclikeyokuqhelekileyo.Ihlalutywe yiTeflonhigh-temperaturecl. umenzi we-othmanufacturer–JiangsuAokaiNewMaterialTechnologyCo.,Ltd., ukudityaniswa phakathi kwezi zinto zimbini zinendlela ephucukileyo ephunyeziweyo ngokusebenzisa umzimba wecalanchoring kunye nokutshixana ngoomatshini, kongezwe ngonyango lokuqala okanye ukunyibilika kwento ehlanganisiweyo.

Iindlela ezithe ngqo zokubamba ilaphu leTeflon lobushushu obuphezulu ziquka oku kulandelayo:

1.MechanicalInterlocking(PhysicalBonding) Le yeyona ndlela ingundoqo.Ifayibhas yeglasi esetyenzisiweyo.Xa i-PTFEemulsionordispersionisimileleyokokwekwekwelaphu yeglasi,i-PTFE ingena kwigaba kunye neendawo ezinqumlana phakathi kweefayibha.Emva kokomisa kunye nobushushu obuphezulu. intering(malunga ne-360–400°C), i-PTFE amasuntswana anyibilika kwifilimu eqhubekayo, ibambe ngokuqinileyo iinyanda zefibernjengezingabaleki'ii-anchorhooks.'Noko kunjalo, ukuthembela kuphela kule ndlela kusekho iziphumo zamandla okudibanisa okulinganiselweyo, kwaye ifuna imilinganiselo eyongezelelweyo ngokubanzi.

2.SilaneCouplingAgentPretreatment(ChemicalBridging)

Le iphantse ibeyeyona nkqubo iphambili kuzo zonke ezikumgangatho ophezuluPTFE iifayibha zegilasi ezikumgangatho ophezulu.

I-Theotherend,amaqela asebenzayo asebenzayo,i-cancross-linkorstronglyadsorbwiththheadhesive partsinthefluorinatedprimerixesha lokumitha kokulandelayo okanye icoating.Oku kwakha ngokufanelekileyo'i-molecularbridge' phakathi kwe-organicandinorganicinterfaces.

3.ChemicalPrimerTransitionLayer

Ukwaleka ngokuthe ngqoPTFEIziphumo zokunganyaniseki kokuncamathela emva kokudibanisa,okwakunikezelwe ngokuphambiliimeyidi idla ngokusetyenziswa okokuqala kwifayibha yeglasi.

I-Adhesiveresins: I-Sukaspolyamide-imide(PAI), i-polyphenylenesulfide(PPS), i-polyethersulfone(PES), okanye i-polyetheretherketone(i-PEEK), enezinto ezintle ezimanzi kwaye zomelele kwiifayibha zeglasi, kwaye ziyakwazi ukumelana nenkqubo elandelayo yobushushu obuphezuluPTFE.

PTFEmicropowder: Ukuqinisekisa ukuba eyokuqala kunye neyokugqibelaPTFEtoplayer canfuse together.

Olu luhlu lwangaphambili luneziphumezo zekhemikhali ibhondi kunye nokudityaniswa komzimba kunye nefayibha yeglasi edityanisiweyo, yenze isakhelo sokutshintsha kwelayile.

4.Hot-MeltAdhesiveFilmLamination(LaminationMethod) Le ndlela,iqeshwe yiJiangsuAokaiNewMaterialTechnologyCo.,Ltd.,isetyenziswa kwibondpre-formed,thickPTFEfilmstofiberglassfabric.BecausePTFEhasanextremelyhighmeltviscosity(iqikelelo) ately10⊃1;⁰–10⊃1;⊃2;Pa·s),ayiqukuqeleli kasixhenxe xa ishushu ngaphezu kwendawo yokunyibilika,sodirecthot-pressbondingingiakwenzeki.I-Amelt-processable'incamathelisi eshushu-enyibilikayo'kufuneka isetyenziswe, ngokwesiqhelo: FEP(fluorinatedethylenepropylene)orPFA(perfluoroalkoxy) films ,eneengongoma zokunyibilika ngaphantsi kunePTFE(malunga nama-260–310°C).Emva kokunyibilika,ziyakwazi ukumanzisa ifayibha yeglasi ngefabricandinter-diffuse/nyibilika ngePTFEfil msurface.Intheprocess,theFEP/PFAfilmsplaced betweenthePTFEfilmandthefiberglassfabric,heatedandpressed,andaftercooling,astrongbondisformed.

5.Ulwakhiwo lweGradient ngeMijikelo emininzi yokuKhulelwa kunye neSintering

Ubushushu obuphezulu obugqithisa amabhanti kunye nemembrane yezolwakhiwo zivelisa inkqubo yokumitha kaninzi: Ukukhulelwa kokuqala kusebenzisa idilutePTFE ukusasazwa okuqulathe izibophelelo kunye nezidibaniselwano, ivumela eyokuqala ukuba ingene kwimiqulu yefiber. Emva kokungena,ukukhulelwa okuninzi okulandelelanayo kunye ne-PTFEemiyelelo esulungekileyo kunye namanyathelo alandelayo adibanisa ayakhutshelwa ngaphandle, okukhokelela ekunyukeni kokunyuka kokucoceka okuphezulu kwePTFEemphezulu. Oku kudala isaleko esakhiwe ngokwendalo enoguqulo olunotshintsho ukusuka kwifayibha yeglasi yefabrictothepurePTFE,kunye noxinzelelo lwangaphakathi oluphantsi kunye nokunyanzeliswa okuqinileyo.

Ukuqukumbela

Isishwankathelo, ukudityaniswa phakathi kwePTFE yokugquma kunye nefayibha yeglasi yefabricinTeflonhigh-iqondo lobushushu ilaphu alithethi nje'ukuncamathelisa'-yenza intsonkothile(inkqubo yobunjineli yenkqubo):ngokudlula kwiphysicalanchoringtotakerootinthreefibers, ngokusebenzisacoucou iintsimbi kunye neeprimers ukuze kuphunyezwe iikhemikhali ibhondi kunye noguqulo, kunye nobushushu obuphezulu-ukudibanisa ukugqiba ukunyibilika-udibaniso lwezalethi zefilimu.Ibe kuphela ipurePTFE zityatyiswe ngokuthe ngqo, lonke uluhlu olunokwenziwa ipeeloff kunye neleyile enye.

Olu lwazi lungentla lunikezelwe nguJiangsuAokaiNewMaterialTechnologyCo.,Ltd. Ukuba ungathanda ukufunda ngakumbi malunga neeparitha ezineenkcukacha, iinkqubo zesicelo, kunye nezisombululo zokwenza ngokwezifiso kwiimveliso zethu ezipheleleyo-kuquka iTeflonhigh-temperaturecloth, Teflonhigh-temperaturetap e,iTeflonhigh-iqondo lobushushu beshbhanti,amabhanti angenamthungo omatshini wokulamisa,icala elinyePTFE ilaphu,amabhanti okuhambisa ubushushu obuphezulu,ilaphu leglasi yobushushu obuphezulu,kunye-ngaphezulu-nceda uzive ukhululekile ukufowunelwa: ~!phoenix_var143_1!~
