Izinga lokushisa kanye ne-Viscosity Attenuation ye-PTFE High-Temperature Tape

I-Jiangsu Aokai New Materials, umkhiqizi ochwepheshe we-PTFE high-temperature tape, uchaza izinguquko zokusebenza kwe-PTFE tape ngemva kokusetshenziswa okuphindaphindiwe kwe-ovini.Ukunciphisa ukumelana nezinga lokushisa nokubamba i-viscosity ikakhulukazi ku- adhesive layer , kune-PTFE substrate. Isakhiwo samangqamuzana e-PTFE substrate izinzile ngokwedlulele futhi asikho iminyaka engaphansi kuka-260°C. Ngokuphambene, izendlalelo zokunamathela ezisezingeni eliphezulu ezifana ne-silicone ziguga ngaphansi kokushisisa okuphindaphindiwe, okugcina kunquma impilo yesevisi ye-PTFE itheyiphu yezinga lokushisa eliphezulu.

1. Umthetho Wokuncishiswa Wokumelana Nezinga lokushisa

Izinga lokushisa le-ovini elivamile (≤ 260°C) Okunamathelayo kudala kancane futhi ngokuqhubekayo, nokumelana nezinga lokushisa kwehla unyaka nonyaka. Ukuphila kwayo kwenkonzo yesikhathi eside cishe iminyaka engu-1-3.

Izinga lokushisa elingaphezulu kancane (260–300°C) Ukuguga okunamathelayo kushesha kakhulu, futhi impilo yesevisi yehla kakhulu isuka eminyakeni embalwa iye emavikini ambalwa kuphela.

Izinga lokushisa elibi kakhulu (°300°C) Ingcina iyathambisa, ibole futhi ikhiphe ngisho nekhabhoni ngokushesha, okuholela ekulahlekeni kwe-viscosity ngokushesha kanye nokuxebuka ngesikhathi esifushane.

Ukuhamba ngebhayisikili okushisayo okuphindaphindiwe Ukushisa okuvama ukushesha nokupholisa kudala umthelela wengcindezi yokushisa, kubangele ukubola okuncane phakathi kwe-adhesive ne-substrate, futhi kusheshise ukwehluleka ukumelana nezinga lokushisa.

2. Attenuation Law of Holding Viscosity

Ukwehla kancane kancane ngaphansi kwezimo ezijwayelekile zokusebenza Ngaphakathi kwebanga lokushisa elilinganiselwe, i-viscosity yokubamba iyancipha kancane kancane ngokukhula kwemijikelezo kahhavini, futhi ungqimba olunamathelayo luba lukhuni futhi lube lukhuni ngokuhamba kwesikhathi.

Ukuncipha okubukhali ngaphansi kwezimo ezishisa kakhulu nezinzima Uma sekushisa ngokweqile noma kuvezwe emithonjeni yamakhemikhali, amandla okubopha angase ehle ngaphezu kuka-50% ngemva kokupholisa.

Iphuzu elibalulekile lokwehluleka kokusebenza Ngisho noma itheyiphu ihlala ingashintshile ekubukeni kwayo, izakhiwo zayo ezingabambeki nokubamba zingase zehluleke kusenesikhathi, ezidinga ukushintshwa ngesikhathi.

3. Izinto Ezibalulekile Ezisheshisa Ukwehliswa Kwezinga Lokusebenza

I-adhesive yohlobo lwe -Silicone enamathela kungcindezi ifaka ukumelana nezinga lokushisa elifinyelela ku-260°C, liphakeme kakhulu kune-adhesive ye-acrylic (120-150°C kuphela).

Isakhiwo se-substrate itheyiphu ye-PTFE eqiniswe nge-Fiberglass iletha ukuqina okuhle kakhulu kobukhulu kanye nokumelana nokukhuphuka okushisayo, nempilo ende yesevisi kunetheyipu yefilimu ye-PTFE emsulwa.

Indawo yokusebenza Ukungqubuzana ngesikhathi sokusebenza kukahhavini, kanye nokuxhumana nezinyibilikisi noma ukugeleza, kuzobhebhethekisa ukuwohloka komzimba namakhemikhali.

Ikhwalithi yezinto ezibonakalayo Amateyipu ekhwalithi ephansi ngokuvamile anokumelana nezinga lokushisa okungelona iqiniso, ukuguga ngokushesha futhi ahluleke ngemva kwemijikelezo embalwa kahhavini.

4. Izincomo Zokusetshenziswa Zokunciphisa Ukuwohloka

Ukulawula izinga lokushisa okuqinile Gcina izinga lokushisa lesikhathi eside eliqhubekayo lokusebenza lingaphansi kuka-260°C futhi ugweme ukusebenza okungaphezu kwezinga lokushisa.

Ukukhetha imodeli okunengqondo Khetha itheyiphu ye-PTFE esekwe ku-silicone yekhwalithi ephezulu, engamelana nemijikelezo engaphezu kuka-500 ku-SMT nezinqubo ezifanayo.

Ukufakwa okujwayelekile Hlanza ngokuphelele indawo ebophayo nge-ethanol ngokuphelele ngaphambi kokucwenga ukuze uqinisekise ukucindezeleka okufanayo kanye nokulingana okuqinile.

Ukwenziwa ngcono kwenqubo Yehlisa imvamisa yokushaqeka okungadingekile okushisayo ukuze unciphise ukulimala kokucindezeleka okushisayo kwesendlalelo sokunamathela.

Isitoreji esifanele Gcina itheyipu engasetshenziswanga endaweni evalekile, emnyama, epholile futhi eyomile ukuze uvimbele ukuguga ngaphambi kwesikhathi kwe-adhesive.

Ukushintshwa okufika ngesikhathi Kudingeka ukushintshwa ngokushesha lapho ukucwecwa kwe-coating, ukubola kwe-carbonization, ukuwohloka konqenqema noma ukulahleka kokusebenza okungeyona induku kwenzeka, ukuze kuqinisekiswe ukukhiqizwa okuzinzile.

Okuqukethwe okungenhla kunikezwa i-Jiangsu Aokai New Material Technology Co., Ltd.

Uma udinga imingcele enemininingwane, izimo zohlelo lokusebenza kanye nezixazululo ezenziwe ngokwezifiso zomugqa wethu womkhiqizo ogcwele ohlanganisa izindwangu ze-PTFE ezishisa kakhulu, amateyipu e-PTFE okushisa okuphezulu, amabhande ane-mesh we-PTFE, amabhande e-fuser angenamthungo, indwangu ye-PTFE enohlangothi olulodwa, indwangu engamelana nokushisa okuphezulu ukuze uzizwe ukhululekile ingilazi ye-fiber:
