Kungani Indwangu Ye-Glass Fiber Ingaphansi Kokukhishwa Kwewaxing Ngaphambi Kokukhulelwa Nge-PTFE Emulsion? Siyini Isimiso?

Njengomkhiqizi ochwepheshe wezindwangu ze-PTFE ezishisa kakhulu, i-Aokai New Materials yenza ukwelashwa okunezinga lokushisa eliphezulu endwangu ye-fiber yengilazi. Ngaphambi kokukhulelwa nge-PTFE (Polytetrafluoroethylene) emulsion, indwangu ye-fiber yengilazi ikhishwa ngewaxing kanye ne-degumming ukuze isuse ama-sizing agents (izinsimbi zendwangu) endaweni yefayibha. Lezi zinsiza zisebenzela ukuhlanganisa, ukuthambisa kanye nokuvikela ngesikhathi sokudwetshwa kwefayibha kanye nokuluka. Kodwa-ke, uma zingasusiwe, zizolimaza kakhulu ikhwalithi eyinhlanganisela ye-PTFE ne-glass fiber. Izimiso ngokuyinhloko yilezi ezilandelayo:

1. Khipha Izinto Zamandla Asezindaweni Eziphansi futhi Uthuthukise Ukumanzisa

Upharafini, uwoyela wokugcoba nezinye izakhi ezilinganisweni zokulinganisa ziyizinto ezisezingeni eliphansi zamandla. Uma igcinwa, i-emulsion ye-PTFE (ene-high surface tension kodwa izidingo eziqinile) ayikwazi ukusabalala ngokulinganayo endaweni ye-fiber yengilazi, okuholela ekulimaleni okufana nama-craters namehlo ezinhlanzi. Ngokuhlanzwa kwezinga lokushisa eliphezulu noma ukuhlanzwa kwe-solvent, ukungcola kuyasuswa futhi amandla angaphezulu we-glass fiber ayanda, okuvumela ukumanzisa okugcwele nge-PTFE.

2. Vimbela I-Carbonization kanye Ne-Delamination Ngesikhathi Sokushisa Okuphezulu Kwe-Sintering

Izinga lokushisa elishisayo le-PTFE liphezulu njengo-360–380°C. Izinsalela zikapharafini noma izinamatheliso ze-epoxy endaweni ye-fiber yengilazi zizoba carbon kumazinga okushisa aphezulu kangako, zikhiqize izinhlayiya ezimnyama noma igesi. Lokhu akungcolisi kuphela okuphakathi (okuthinta izakhiwo ze-dielectric kuma-laminates agqoke i-copper-frequency high-frequency) kodwa, ngokujulile, ungqimba lwe-carbonized lwakha isikhombimsebenzisi esibuthakathaka, sinciphisa kakhulu amandla okubopha phakathi kwe-PTFE ne-glass fiber futhi kubangele i-delamination yezinto ezihlanganisiwe.

3. Misa Umphumela Oqinile 'Wokunamathisela Kwemishini'

Ikhwalithi ephezulu ye-dewaxing kanye ne-degumming (ikakhulukazi ukwelashwa kokushisa okusezingeni eliphezulu) kungaphezu 'ukuhlanza'. Njengoba izinto eziphilayo zisuswa, i-glass fibre surface iqoshwa kancane ukuze yakhe ama-micropores noma iveze amaqembu e-silanol amaningi (-OH). Lokhu kudala izimo zokulandelana kwe-ejenti yokuhlanganisa (isb, i-phenyl silane), okuvumela i-PTFE ukuthi yakhe amabhondi amakhemikhali noma amaphoyinti okubambelela aphathekayo nge-glass fiber ngokusebenzisa ama-coupling agents — ukuguqula 'ukunamathela' okulula kube 'ukubopha' okuqinile'.

4. Gwema Ukuwohloka Kwezakhiwo Ze-Dielectric Interfacial

Kuzicelo eziphezulu ezifana ne-high-frequency kanye ne-high-speed copper-clad laminates, izinto ezisele ze-polar eziphilayo (i-wax, i-gum) zandisa kakhulu ukulahlekelwa kwe-dielectric ngaphansi kokushisa okuphezulu kanye nemvamisa ephezulu. I-Dewaxing kanye ne-degumming iqinisekisa ukuthi i-glass fiber-PTFE composite igcina ukulahleka kwe-dielectric ephansi kakhulu kanye nokulahlekelwa kwe-dielectric.

Kafushane, inhloso eyinhloko yalokhu kwelashwa ukuqeda izendlalelo zesixhumi esibonakalayo esibuthakathaka nokuqinisekisa ukuthi i-PTFE, impahla yamandla engaphezulu ephansi, ifinyelela ukumanzisa okuphelele nokubopha okunamandla ku-fiber yengilazi ehlanzekile, ephezulu-eneji elingaphezulu.

Ulwazi olungenhla lunikezwe i- Jiangsu Aokai New Materials Technology Co., Ltd.

Ukuze uthole imingcele enemininingwane, izimo zohlelo lokusebenza nezixazululo ezenziwe ngokwezifiso zohlu oluphelele lomkhiqizo wethu - okuhlanganisa izindwangu ze-PTFE ezishisa kakhulu, amateyipu e-PTFE okushisa okuphezulu, amabhande anezikhala we-PTFE, amabhande angenamthungo emishini yokubopha, indwangu ye-PTFE enohlangothi olulodwa, ingilazi emelana nokushisa okuphezulu, ingilazi engavimbeli ukushisa futhi uzizwe ukhululekile ukuthintana. thina:
