Iphethini yoshintsho emandleni ahlangene wesendlalelo sokunamathisela se-Teflon itheyiphu yokushisa okuphezulu ngemva kokuguga okuphezulu.

I.PatternofChangeinAdhesiveLayerCohesionUnderHigh-TemperatureAging

Isigaba sangemva kokuphulukisa: Isigaba sokuqala sokuchayeka emazingeni okushisa aphezulu(isb,200–260°C),iqembu elisele elisebenzayo liyaqhubeka nokunqamula isixhumanisi,okuholela ekubalulekeni okubalulekilekukhuphuka kokuhlanganisa.Ivela yokunamathisela iyabaqina,futhi imelane nokunamathelayokuminyanisa ukuphuphuma.

Isiteji sokulingana okuzinzile: Inkinga yokuhlangana isondela ekuqedeni, kanye nokuhlangana kusalokhu kuzinzile esikhathini esidlule.Kulesi sigaba, itheyipu ibonisa ukusebenza kahle futhi ingakwazi ukumelana nezinga lokushisa eliqhubekayo lokusebenza.

Ukuwohloka nokuwohloka kwesiteji: Isikhathi esingaphansi ngokweqile noma izinga lokushisa eliphansi kakhulu, iketango eliyinhloko lingaphansi kokuwohloka, okubangela ukuba kunciphe ngokuqhubekayo.Isivela esinamathelisi siyathambisa futhi sibe sishubile, okwenza kube lula ukubekezelelana ukuhlangana kwehluleke nokumpintsha.

II.I-RootCausesofcohesiveFailureandAdhesiveSqueeze-Out

Imbangela yokwehluleka okuhlangeneyo: Lapho amandla okuhlangana aqinile futhi asenhlokweni avela ngaphansi kokuqina kokunamathela kobuso obuhlangene, izinyembezi zangaphakathi zenzeka, zishiya insalela enamathelayo.

Imbangela yokuminyanisa ngaphandle: Amazinga okushisa ancibilikisiwe, imodulus iyehla, kanye nengxenye enamathelayo ngaphansi kokugeleza okubandayo, ikhishwe isuka emaphethelweni ngusisikazi oshisayo.

Ubudlelwano phakathi kwakho kokubili: Ukuwohloka kwesikhathi eside kubhebhethekisa lezi zindaba kanyekanye;ukunganele ukuxhumanisa okuphambene okuqondile kuholela ekuminyaniseni-ngaphandle kwesigaba sokuqala.

III.UkuvimbelaNgokwakhiwaNenqubo Yokunamathela

Ukwakheka kokuklama: Sebenzisa i-high-phenylsilicone, amasistimu okwelapha okokwengeza anokulawula ukuxhumanisa okuphambene, ibhalansi ye-MQresinratios, i-addreinforcingfillers, andeliminate low-molecular-weightplasticizers.

Ukwemboza nokuphulukisa: Sebenzisa ukwelashwa okuphelele kwangemuva kokuphulukisa susa izinto eziphansi ze-molecular-weightfuthi uvimbele ukuminyanisa-uphume ngesikhathi sokuchayeka kokuqala.

Isakhiwo sendawo yokunamathisela: Ubukhulu bokunamathisela kufanele kubebekeptthin(≤25μm), kanye ne-0.5–1mmadhesive-freesafety margin kufanele kuhlinzekwe emaphethelweni e-gestophysically blocksqueeze-out.

IV.Ukuvinjelwa Ngezimo Ezingaphansi Nezimo Zokusebenza

I-Substrateanchoring: Ifilimu ye-PTFE idinga ukwelapha noma ukwelapha i-plasma, ihlanganisa ne-primertomatchinterface kanye namandla ahlangeneyo,ukuvimbela i-anchoring eyeqile engaholela ekuhlulekeni okuhlangene.

Ukulawulwa kwezinga lokushisa: Landela ngokuqinile izicaciso zokushisa ezilinganisiwe zokusetshenziswa, sebenza kancane kancane ngokushisa, futhi ugweme ukuthuthumela okushisayo.

Isitoreji nokubamba: Isitolo flatukushisa okuphansi kwezinga lokushisa ukuze kuvikelwe ukugeleza okubandayo, vumela i-tapetore ukuthi ibuyele emazingeni okushisa egumbi ngaphambi kokusetshenziswa, futhi uqinisekise ukuthi ubuso obuboshiwe buhlanzekile futhi abukhululekile.

Ulwazi olungenhla luhlinzekwa nguI-JiangsuOKNewMaterialTechnologyCo., Ltd.

Uma ungathanda ukufunda okwengeziwe mayelana nemininingwane ecacisiwe, izimo zohlelo lokusebenza, kanye nokwenza ngendlela oyifisayo izinketho zemikhiqizo yethu egcwele-okuhlanganisa i-PTFEhigh-temperature tape,PTFEhigh-temperaturetape,Teflonhigh -amabhande anomeshi wezinga lokushisa,amabhande angenamthungo anamathelayo,indwangu yohlangothi olulodwa lwePTFE,amabhande okuhambisa ezinga lokushisa eliphezulu,nendwangu yengilazi enezinga lokushisa eliphezulu—sicela uzizwe ukhululekile ukuthintana ngalezi ziteshi ezilandelayo:
